Reviewing Recent Developments on Research of Internationalization of Brazilian Firms Autoria: Mário Henrique Ogasavara, Gilmar Masiero The internationalization of Brazilian companies has received considerable attention by researchers seeking to understand the factors driving the increasing amount of investments made by Brazilian firms in world markets. This study attempts to review recent research on the internationalization of Brazilian companies based on an analysis of the 94 most recently published articles that have appeared in Brazilian academic journals, books, and in the conference proceedings of the EnANPAD. It seeks to provide a typology of the leading researchers and school affiliations, a characterization of the predominating theoretical and methodological approaches employed in these studies, as well as to undertake a citation analysis to identify the most cited scholars, research topics, and outputs from research on the internationalization of Brazilian multinationals (I-BM). We find that I-BM research is driven by a small number of leading institutions and researchers who tend to primarily utilize case studies as their research method. The most frequently used theoretical approaches are the Uppsala and Eclectic OLI models. Our citation analysis of a total of 2,583 references revels that there is a higher quantity of citations referring to foreign-origin publications produced in international journals and translated books. We also find that studies published in Brazilian journals are a relatively minor share of the total body of literature and that there are an insignificant number of cited papers published by Brazilian scholars in international outlets. We conclude by providing a set of recommendations to advance I-BM research stressing that studies should move beyond replicating approaches developed in other settings, employ qualitative and quantitative research with a larger sample of cases and target publication in leading peer-reviewed international journals. 1. Introduction Recently, the topic of internationalization process of multinationals from emerging countries, such as Brazil, has received considerable attention by both academics and entrepreneurs. The increasing interest in this theme is due to the rapid growth of outward foreign direct investment (OFDI) flows from firms based in emerging markets (Sauvant, 2008). Although foreign investment from these developing countries seems to be a new phenomenon, in fact, this movement is not recent. Indeed, the first registered case dates to 1890 when an Argentine firm undertook significant foreign direct investment (FDI) in Latin America (Katz and Kosacoff, 1983). In terms of academic publication, the subject had already received a considerable amount of attention in the late 1970s and early 1980s beginning with Lecraw (1977), Lall (1983) and Wells (1983) who together offered a theoretical explanation for the specific characteristics of “Third World” multinational enterprises. A first wave of investments was made in the early 1980s primarily by Latin American firms, while the second wave emerged in the early 1990s driven by the flows stemming from Asian Newly Industrializing Economies (Dunning et al., 1996; Chudnovsky and Lopez, 2000). Differently from the first wave of FDI, which was characterized mainly by investments directed at neighboring and other developing countries with similar or in earlier stages of economic development (Lall, 1983; Wells, 1983), the current wave has continued to direct resources to emerging markets and also expanded investments in developed countries including with a number of high-profile acquisitions. For instance, some Brazilian multinationals have gained attention in the business press by their successful merger and acquisition (M&A) deals of sizeable assets abroad. These huge deals include: Ambev, South America´s largest beverage company, acquired John Labatt Ltd (Canada) for US$ 7.8 billion in 2004 (Sauvant, 2005); JBS-Friboi, Latin America’s largest meat producer, acquired US-based Swift for US$ 1.4 billion in 2007 making the new company the most powerful force in the global beef business (Boston Consulting Group, 2007) and the Brazilian mining company Vale (formerly known as CVRD, Companhia Vale do Rio Doce) 1 took over Canadian-based INCO (International Nickel Company, Ltd.) in 2007 for US$ 16.7 billion (Sauvant, 2008). This pattern of internationalization driven by cross-border M&A has significantly impacted Brazil OFDI flows. With the exception of 2005, since year 2004 OFDI flows reached levels at least of US$ 7 billion and averaged US$ 13.6 billion in the last five years (2004-2008). Additionally, in 2006 for the first time ever Brazil FDI outflows (US$ 26 billions) surpassed FDI inflows. There have been a number of important summaries completed to synthesize the development of Brazilian academic research in the management field. Reviews have been completed on organization studies (Machado-da-Silva et al, 1990; Bertero and Keinert, 1994; Vergara and Carvalho, 1995; Rodrigues and Carrieri, 2001; Vergara and Pinto, 2001), marketing (Froemming et al., 2000a, 2000b; Botelho and Macera, 2001; Vieira, 2003), strategy (Gosling and Gonçalves, 2004; Bignetti and Paiva, 2002), finance (Leal et al., 2003), operation management (Arkader, 2003), corporate social responsibility (Jabbour et al., 2008), human resource management (Roesch et al., 1997; Siqueira, 1998; Caldas et al., 2003; Tonelli et al., 2003; Caldas and Tinoco, 2004), entrepreneurship (Paiva and Cordeiro, 2002), the non-profit sector (Izuka and Sano, 2004), and information systems (Hoppen, 1998, Lunardi et al., 2005; Meirelles and Hoppen, 2005). Surprisingly, however, a research review on international management with a focus on I-BM studies has yet to be undertaken. This paper aims at addressing this lacuna by reviewing the most recent articles that have been published on I-BM. The next section explains the methodology that was employed to select the sample of research reviewed for this study. After describing the sample, we present our findings based on the total sample of recently published book chapters, articles identified from the EnANPAD proceedings and Brazilian journals in five areas. We use these findings to provide a set of recommendations on how I-BM research should be advanced in the concluding section of this study. 2. Methodology In order to select the sample of I-BM research for this study, an extensive bibliographic search was undertaken of academic papers and the catalogs of the most respected commercial and university publishers. Seven books published since 2000 were identified (Rocha, 2002, 2003; Fleury and Fleury, 2007a; Almeida, 2007; SOBEET, 2007; Vasconcelos, 2008a, 2008b). In addition, the study selected papers that were presented and published in the last five years (2004-2008) as part of the EnANPAD (Encontro Nacional da Associação Nacional de Pós-Graduação e Pesquisa em Administração) proceedings. Since 1976, the National Management Association (ANPAD) has organized annually an academic meeting (EnANPAD) where professors, researchers and graduate students present and discuss a variety of subjects in the fields of management and accounting. The international business field of study has been considered as a sub-area in the Strategy in Organizations Academic Division since 2005. Finally, this review considered papers on IB-M that were published in most relevant Brazilian academic journals classified as Qualis Capes “A”. As the phenomenon of the second wave of the internationalization of the Brazilian companies is quite recent, the sample is representative of research efforts that have been undertaken in the field. Once the sample was collected, a second step was undertaken to ensure that only the set of articles directly related to I-BM would be analyzed for this study. It should be noted that this study departs from the premise that the internationalization process is defined by whether a multinational company engages in investing outside its borders. Therefore, articles that contain cases and information of Brazilian firms that acquired assets abroad by buying existing companies, as well as those who established greenfield or joint venture (JV) investments were included. Studies limited to research on the exporting activities of these firms, however, were not considered with the exception of those articles that also included findings related to how the same firm also invested abroad. 2 Lastly, a careful examination of each article was performed to identify the state of the art of I-BM studies with the aim of identifying the contributions of specific authors and leading institutions, as well as to categorize the sample, methodologies and theories used in each study. Two methods were employed to construct total and adjusted count measures for the contributions of authors and institutions. A more detailed explanation of these measures is presented in the results section. Finally, the reference literature of I-BM research was identified by performing a citation analysis. The citations of national and foreign scholars and self-citations were tabulated with controls made to track the language of the cited reference and the most frequently used outlets for I-BM research. As a result of these efforts, a ranking of the most cited authors and research used by Brazilian scholars was developed. 3. Sample The “boom” of international business research in Brazil or of the internationalization process of Brazilian multinationals is quite recent, at least, in its second phase characterized by large amounts of FDI being allocated in developing as well as developed countries or markets. A total of 94 articles were considered for this first I-BM review: 39 derived from books (book chapters), 41 from EnANPAD proceedings, and 14 from academic journals. The majority of book-related chapters are included in edited volumes, in other words, authors that organized the manuscript by gathering a number of articles from different authorships. As mentioned earlier, seven books were identified for this research review. Rocha (2002, 2003) organized two volumes based on the studies developed in the Research Center of Firm Internationalization at the Federal University of Rio de Janeiro (Universidade Federal do Rio de Janeiro,UFRJ). Most of the articles were written based on theses and dissertations previously presented at the COPPEAD Graduate Business School at UFRJ to obtain the Master’s or Doctoral degrees. For this review, we selected four articles from Rocha (2002) and six from Rocha (2003). Fleury and Fleury (2007a) edited a book based on papers presented at the International Workshop in Firm Internationalization organized in 2003 to celebrate the 60th anniversary of the School of Economics, Business Administration and Accountancy in the University of Sao Paulo (Faculdade de Economia, Administração e Contabilidade,USP). Eight papers from the edited version of Fleury and Fleury (2007a) qualified and were included in our review. More recently, Vasconcellos (2008a, 2008b), also at USP, structured two books based on articles developed by scholars linked to the Research Center of Policy and Technology Management (Núcleo de Política e Gestão Tecnológica – NPGT/USP) who have been involved on the thematic project called GINEBRA - Enterprise Management for Internationalization of Brazilian Companies (Gestão para Internacionalização de Empresas Brasileiras). We included seven articles were considered from Vasconcellos (2008a) and five from Vasconcellos (2008b). Almeida (2007) gathered a range of articles from a specialist team of the International Business Center of Dom Cabral Foundation (Fundação Dom Cabral) located in Minas Gerais State (Southeast region). We selected seven articles from the volume edited by Almeida (2007). SOBEET (2008), which is the Brazilian Society of Studies on Transnational Companies and Economic Globalization (Sociedade Brasileira de Estudos de Empresas Trasnacionais e da Globalização Econômica) located in Sao Paulo, prepared a book based on the findings obtained from a thematic study focused on the internationalization of Brazilian companies. This thematic study was promoted as main discussion topic for the 2005/2006 Leaders Forum (Fórum de Líderes), a non-profit organization formed by businessmen (CEOs, directors, VP, etc.) from all industry sectors in Brazil. We included two chapters from this edited volume. For the EnANPAD proceedings, most of the articles were picked from the Academic Division of Strategic in Organization, particularly from the International Management area, which is the academic field related to the discussion of internationalization process, multinationals, exporting activities, expatriates, etc. It should be noted, however, that some 3 articles from other Academic Divisions that are associated with the I-BM field were also taken into account from fields such as international marketing, agribusiness, public administration, finance, and entrepreneurship. Our total sample comprises four papers from 2004, four from 2005, seven from 2006, eleven from 2007, and fifteen from 2008. It should be noted that the majority of the sample distribution (63%) for the papers published in the EnANPAD proceedings are from studies produced in the last two years. The growing interest in I-BM subject might be related to the surge of Brazil OFDI flows since 2006 leading to record levels. For Brazilian academic journals, the sample is based on articles published in outlets evaluated by Qualis Capes. This is publication ranking index conducted since 1998 by the Coordination for the Improvement Higher Education Personnel (Coordenação de Aperfeiçoamento de Pessoal do Nível Superior, Capes), which is the government entity that evaluates the intellectual production of graduate schools in Brazil. Qualis Capes provides a list of academic journals/events and classifies them based on a quality index comprised of “A”, “B”, and “C” levels, and whether the particular activity/publication has an international, national or local impact. A classification of Qualis “A” means a high quality outlet/event. Since March 2009, Capes changed the Qualis classification by excluding international, national and local impact classification and expanding the three to eight categories (A1, A2, B1, B2, B3, B4, B5, and C). Since the data collection was carried prior to March 2009, this paper adopts the initial Qualis Capes classification and only reviewed articles published by journals that were classified as Qualis “A”, which represents the most relevant academic journals in the business field. A total of fourteen papers were identified from seven different journals: 3 articles from RAE (Revista de Administração de Empresas da Fundação Getúlio Vargas); 2 papers from RAC (Revista de Administração Contemporânea); 5 articles from ReAD (Revista Eletrônica de Administração); and 1 paper from each of the following journals RAUSP (Revista de Administração da USP), RAM (Revista de Administração Mackenzie), BAR (Brazilian Administration Review), and BBR (Brazilian Business Review). 4. Results and discussion In this section, we present our findings on the total sample of recently published book chapters and articles identified from the EnANPAD proceedings and Brazilian journals. First, we present a summary of the leading authors and their institutional affiliation in our total sample of 94 articles. Given the large number of studies that were the product of joint authors, we summarize the types of collaborations that most often led to collaborative publications. Secondly, we provide a typology of the dominant methodological and theoretical approaches used in I-BM research, as well as the companies that have most often been the subjects of study. Thirdly, we present the results of the citation analysis of the 2,583 references cited by the sample of 94 articles we reviewed for this study. Fourth, we summarize the types of references (books, peer-reviewed articles, etc.) most often cited by national and international-origin publications showing that there are marked differences in the body of literature cited by a study depending on its publication outlet (foreign or domestic). Finally, we report the top 22 authors that were most-often cited in the references. 4.1. Authors and institutional affiliation The number of authors per article in book chapters, EnANPAD proceedings, and academic journals is presented in Table 1 and the distribution follows a similar pattern. Of the total 94 articles that were analyzed, 81.9% were written by multiple authors (54.3% by two authors), while 18.1% of selected papers had a single author. The preference for writing research papers as part of collaboration with another person(s) is confirmed by this analysis. The fact that articles have more than one author could be due to two reasons. On the one hand, this type of article could be the result of collaborative research undertaken by scholars from the same or different institutions to develop research projects and work in teams as means for 4 producing critical insights and interactions that multiply with the exchange of knowledge and ideas in teams. On the other hand, this article could be the result of the relationships forged between academic advisors and their graduate students.

We therefore identified whether or not authors were undertaking collaborative research (e.g. researchers from the same or different institutions) or producing the results of research stemming from academic advising (e.g. academic advisor and graduate student). Table 2 shows that almost 60% of the multiple-authored articles were written together by an academic advisor and a graduate student. It should be noted that this finding confirms the expectations since graduate students normally present their research papers with his/her academic advisor in the EnANPAD meeting, which is the main association of management for graduate programs.

The methodology used to measure the author contribution is similar to that employed by Morrison and Inkpen (1991) and Inkpen and Beamish (1994). As can be seen in Table 3, two different measures were adopted to rank author’s appearance in order to avoid any kind of inconsistency about each author’s contribution, particularly because there are a large number of multiple-authored articles in our sample. The first measure “adjusted appearances” includes a factor to scale the total number of articles in those cases where papers were the result of multiple authorships and the second measure “total appearances” is the sum of the total number of articles for a particular author. For total appearance, the author receives one full credit as long as his/her name appears on the published article. If a paper was published by two or more authors, a weight based measure was 5 applied according to the number of co-authors. Articles with 2 authors were assigned a weight of one-half of a credit, while those papers with 3 authors received one-third, with 4 authors received one-fourth, and papers with 5 authors were assigned one-fifth of a credit. No distinction was made on the credit allocation between the first author and other co-authors. The review shows that there are a larger number of authors (a total of 130) who have contributed to I-BM. Due to space limitations, Table 3 only presents a ranking of authors with more than 1.0 credit in adjusted appearance measureii. The top 13 names (10% of the total number of authors) represent almost one-third of the total adjusted appearance indicator points. According to Table 3, Angela da Rocha with a total of 11 articles and a weighted score of 4.83 has the highest number of appearances. She was followed by Eduardo Vasconcellos with the same number of articles, but a weight of 4.58. It should be noted that each of them were editors of two books considered in this review and they have been pioneering scholars who have been responsible for the creation of research groups in the I-BM field in their institutions.

Of these 14 authors have 1.00 ADJ and 116 authors have 0.20 to 0.83 ADJ. b c Adjustments are made for multiple-authorships. Credit for an article with 2 authors is 0.5, 3 authors is 0.33, 4 authors is 0.25, and 5 authors is 0.20. Total appearances are the absolute number of articles. The author receives one full credit as long as his/her name appears on the published article. An analysis of the author’s affiliation was also conducted. If the author’s home institution was named in the article, this is the affiliation that was assigned a credit. When not available, the Lattes Database (Currículo Lattes,CNPq) was used to code for the author’s institution at the time of the publication of the specific study. The institutional appearance also uses a weight for those articles written by authors from different institutions. In this case, the same methodology considered by Lu (2003) was adopted. For “total appearance”, an institution takes one full credit as long as its name appears in the published article. It should be noted that the maximum credit received by an institution is one as only one credit is allocated in those articles with more than two authors from the same institution. In some cases, an author is affiliated with two different institutions at the same time. In this case, each institution was given one-half credit. There were 51 different institutions identified in the sample. Researchers affiliated with the University of Sao Paulo (USP) had the highest number of contributions to the development of I-BM research. This institution had 25.50 credits for total appearances and a weighted score of 20.34. The Federal University of Rio de Janeiro (UFRJ) follows the ranking with 15.50 credits in total appearances and 15.75 credits in adjusted appearances. Both institutions are public universities while the third, fourth and fifth top ranked institutions (FDC, Unisinos, and Unifor) are private. It is worth noting that the top 3 institutions in the ranking (USP, UFRJ and FDC) have already established research centers on I-BM research. It is evident that this effort has resulted in a higher number of publications from these centers. Most of the top institutional 6 contributors were from the Southeast and South region of Brazil. 4.2. Methodological and theoretical approaches Case studies have been the most commonly applied methodology in I-BM research (62.8% of the total). The same findings were found in other research reviews of the Brazilian management literature such as in strategy (Gosling and Gonçalves, 2004), human resource management (Tonneli et al., 2003), and corporate social responsibility (Jabbour et al., 2008). According to Robson (2002:178), a case study is a “strategy for doing research which involves an empirical investigation of a particularly contemporary phenomenon within its real life context using multiple sources of evidence.” As the I-BM issue is considered a “new” phenomenon, a number of authors in our sample have been applying this technique based on the collection of data from interviews, questionnaires, observation and document analysis. Together these case studies provide a rich body of information about the internationalization process of Brazilian multinationals. However, it should be noted that 62.7% of the case studies’ sample (37 papers) were based on a single firm. To perform hypothesis testing across different companies, Eisenhardt (1989) argues that case studies that include the experience of multiple companies are preferable to single firm case studies. Surveys were used by 21.3% of the studies in the sample. This method involves choosing a target group of companies and sending questionnaires. The larger the sample, the more precisely it reflects the target group. If the sample is small and the response ratio is low, it becomes more difficult to apply quantitative analysis using statistical tools. Of the 20 articles that used a survey design, only four used a sample of 100 or more companies, while seven studies were surveys with a sample of less than 25 companies. Hence, there are few published articles in I-BM research that have performed statistical analysis. The Uppsala and Eclectic Paradigm models have been the mainstream theoretical perspectives most commonly employed in I-BM. The first explains the internationalization process based on the knowledge acquisition (Johanson and Wiedersheim-Paul 1975, Johanson and Vahlne 1977, 1990). The model is based on the assumption that the lack of knowledge about international markets is the major obstacle to foreign operations, but this knowledge can be acquired by an evolutionary and sequential building-up of foreign commitments over time. Twenty-six articles used this model based on the proposition that the internationalization of Brazilian companies followed a process of increasing foreign commitments to international markets. Initially firms had a low commitment level to overseas investment (i.e. indirect and direct exporting) that was followed by the opening sales or representative offices. For these authors, it was only companies had accumulated international experience that they increased their involvement by establishing subsidiaries abroad (i.e. JV or greenfield) or even acquiring assets through cross-border M&A. It should be noted that the application of the Uppsala model in I-BM studies led to different results. While some articles reported findings to support the model (Barreto and Rocha, 2003; Mello and Rocha, 2003; Oliveira and Kovacs, 2007; Fleury et al., 2008; Freitag-Filho and Amal, 2008; Oliveira and Vasconcellos, 2008), others found only partial support (Sacramento et al., 2002). In addition, there are also some studies that argue that the model does not fit to the Brazilian context (Freire and Rocha, 2003; Veiga and Rocha, 2003; Ritossa and Bulgacov, 2008). Due to these contrasting findings, a deeper discussion of the usefulness of this model as a theoretical framework for the Brazilian context seems to be an interesting research question to be explored in future research. Dunning’s (1977, 1980, 1988) Eclectic Paradigm is the second most frequently applied model in I-BM studies with thirteen appearances. This framework is based on three components that determine which firms enter a foreign market that help to delineate the acronym of this theory commonly referred to as OLI: ownership, location and internalization advantages. More specifically, ownership advantages refer to firm-specific advantages related to the possession of asset power, control, and inter-firm relationships. Location advantages refer to the 7 particularities of the market including the availability and cost of resources. Internalization advantages concern the reduction of transaction and coordination costs. The OLI framework was applied and supported in articles related to the internationalization of Brazilian meat companies (Calabria and Pereira, 2008; Pozzobon, 2008). The other six models or theoretical approaches that are commonly used in the international business literature are less used by Brazilian researchers. “International entrepreneurship” - a theoretical base for the study of international new ventures, defined as business organizations that “derive significant competitive advantage from the use of resources and the sale of outputs in multiple countries” (Oviat and McDougall (1994:49) – and “Born global” – companies that start their activities by having a strong presence in international markets from the onset (Rennie, 1993; Knight and Cavusgil, 1996; Madsen and Servais, 1997) were the theoretical methodology of 12 papers. Rocha et al. (2005), Carvalho and Paes (2006), Honório (2007), Pereira et al. (2006), Dib and Rocha (2008), Mello et al. (2008), are examples of these two approaches. The famous Porter’s “competitive advantages” theory, like in Borini et al. (2008), was employed in five articles. Four other studies by Forte and Sette-Jr (2005), Forte and Moreira (2007), Penido and Cyrino (2007) and Fumagalli et al. (2008) adopted the “degree of internationalization” approach (Sullivan, 1994), while four other papers like Hexsel (2004), Forte et al. (2006), and Britto et al. (2008) used the “resource based view” (Barney, 1991; 1997). Three studies such as Borini et al. (2007) and Fleury and Fleury (2007b) used the late movers approach. Most of the findings of these 28 studies in general do not challenge the theoretical basis selected to develop them. Many studies examine the same experience in the still small sample of Brazilian multinationals. Not surprisingly, except for Datasul and Sadia, the most commonly examined firms in I-BM field (Embraer, Natura, Odebrech, CVRD, Gerdau, Petrobras etc.) were almost the same companies listed in the Top 20 Brazilian multinational enterprises ranking in terms of foreign assets released by the Fundação Dom Cabral and The Columbia Program on International Investment (FDC-CPII, 2007). This implies that research interest on a particular firm is positively related to the degree of its internationalization. Although the international spread of Brazilian multinationals has concentrated on resource-based activities (FDC-CPII, 2007), this review shows that authors have also demonstrated an interest in companies related to medium-to high-technology industries including Embraer, Natura, Weg, Marcopolo, Datasul, and Sabó. 4.3. Citation analysis In order to examine the most influential authors, studies, and outlets in I-BM research, a citation analysis was undertaken. We were interested in capturing the reference literature that serves as the foundation for Brazilians scholars working in the field of international business. A total of 2,583 citations were coded. Table 4 summarizes the portion of the studies that cite past research by its authors (self-citation), research published in Brazil and scholarship produced abroad. The first observation in Table 4 refers to the high percentage of citations of foreign scholars (73.9%) with the highest percentage found by studies published in academic journals (80%) followed by EnANPAD proceedings (74.7%) and book chapters (69.4%). This finding follows the same results of prior investigation in other management fields. For instance, Vergara and Pinto (2001) found that foreign citation represented 63.62% of the Brazilian organization studies’ literature, with the majority of sources referring to U.S.-based scholars. In the human resource management area, Caldas and Tinoco (2004) also identified similar outcome (63%) of citation from non-national scholars. More recently, Machado-da-Silva et al. (2008) conduct a bibliometric analysis and report that foreign citations are 52.4% of the studies cited in select Brazilian academic journals in management.

The concentration of citations on foreign sources is positive in the sense that it underscores that Brazilian scholars are in discussion with the international business literature. In other words, Brazilian authors are not isolated and are intensively learning from knowledge produced outside its borders. However, as we have noted earlier, this emphasis also demonstrates negative aspects in the sense that national research is predominantly focused on only describing and replicating foreign approaches. The I-BM literature is clearly recent and hence the advances of the Brazilian academy in this field are still incipient. At present, there is no consistent theory or model that provides support to explain the internationalization process of Brazilian enterprises. Additionally to the theoretical approaches mentioned in section 4.2 above, some scholars (Borini et al., 2007; Fleury and Fleury, 2007b; Rocha et al., 2007) have used the late movers framework (Bartlett and Ghoshal, 2000) as a way to compare the adopted strategies of internationalization of first movers (i.e. multinationals from developed countries) with the experiences of emerging multinationals (i.e. late movers). An interesting finding refers to the considerable number of foreign citations (i.e. books) translated to Portuguese. Of all of the references published in Portuguese, 26.5% were translations of research produced in a foreign language. This implies that some authors preferred to use a translated version rather than the original work. This is indicative of the trend in Brazilian research that has expanded the reading and understanding of foreign materials by their translation into Portuguese. This trend may also reveal that scholars in this area may be more familiar with the Portuguese-version of these studies and less familiar with the original research including terminologies. This pattern may also be a product of the fact that the cost of Portuguese language materials is cheaper and faster as compared to those of imported books. A small number of national scholars in international publications were cited as shown in Table 5. The figure is slightly better for self-citations where 16.5% of 83 references were published in a language other than Portuguese (total of 16 publications: 8 conference papers, 5 academic journals, 3 book chapters). When all citations of national scholars are considered, only 2.3% of the total is derived from research papers published in international outlets (total of 13 publications: 6 academic journals, 4 conference papers, 1 book chapter, 1 working paper, 1 report). This result has several possible explanations: (1) the authors in I-BM area were focusing on research published by foreign scholars; (2) the authors did not intend to cite and promote other national scholars who had published his/her work internationally; (3) there were only a few number of Brazilian scholars in I-BM field who had published academic papers in foreign outlets (i.e. English). Most probably, the explanation is related to this last item. Regarding this issue, Mesquita (2008) suggested a need for national scholars to insert themselves more intensively in the international community by publishing articles in a foreign language. Based on data of published research papers in English and the authors' nationality, he demonstrated that Brazilian scholars are far behind in terms of international publication compared to the performance achieved by researchers from the other members of the BRIC (i.e. China, India and Russia). 9 Table 5 – Language of the cited references in I-BM research National language Foreign language Total Type of citation # # %* %* # Citations %* Citations Citations Self-citation 81 9.3 (83.5) 16 0.9 (16.5) 97 3.8 Citation of national scholars 557 64.2 (97.7) 13 0.8 (2.3) 570 22.1 Citation of foreigner scholars 230 26.5 (12.0) 1,686 98.3 (88.0) 1,916 74.1 Total 868 100.0 (33.6) 1,715 100.0 (66.4) 2,583 100.0 Note: * The first information refers to column percentages, while the figures in parenthesis are the row percentages. 4.3.1. Reference sources and outlets Table 6 shows the types of references most commonly cited in I-BM studies. There is a significant difference in the top 5 sources referenced in domestic and international publications. Books represent the most frequently source of references (almost 40%) for domestic publication, which is similar to the results found in marketing by Vieira (2003) and human resource management by Caldas and Tinoco (2004). An important point to mention refers to the authorship of these books. While Caldas and Tinoco (2004) identified a number of non-academic authors for the books used in the field of human resource management, the majority of cited books were written by academics in the management area in the I-BM field. Reference sources Books Book chapters Web pages Conference Proceedings Academic Journals Others Total Table 6 – Reference sources in I-BM research Domestic Publication Reference sources # Citations % 336 38.7 Academic Journals 117 13.5 Books 87 10.0 Book chapters 86 9.9 Business Magazines 62 7.1 Conference Proceedings 180 20.8 Others Total 868 100.0 International Publication # Citations % 1,016 59.2 375 21.9 102 5.9 66 3.9 45 2.6 111 6.5 1,715 100.0 Book chapters were the second most commonly reference sources (13.5%) for domestic publication including some chapters from the selected books reviewed for this study. Others sources, such as web pages and conference proceedings, were also used. The former was generally based on the company’s homepage information that was used to develop case studies, while the latter relates to articles published in the EnANPAD proceedings. Although some books and book chapters were refereed materials, it should be noted that the majority of sources in these top 4 citations were not the result of a rigorous peer review process. In particular, conference papers are well-known as research that should be considered to be in progress (Bertero et al., 1999). The most frequently book cited as a reference source was a translated book on case study methodology. In fact, 108 (54.3%) of the 199 national published books that were cited were foreign materials translated to Portuguese. In terms of international publication, academic journals are the most influential source in I-BM research. The total number of citations of journal articles in international publications is three times higher than the number of citations of books (375 citations from 222 books). For international outlets, Brazilian researchers are more likely to refer to refereed academic materials in a variety of international journals (total of 1,016 citations from 181 outlets) rather than domestic journals (62 citations from 15 outlets). In the ranking list of the outlets for I-BM research, only Harvard Business Review is not an academic journal. The most influential outlet in I-BM study is the Journal of International Business Studies (JIBS). This sample presents almost three times more citations than the second in the list (Strategic Management Journal, SMJ). In reality, this is an expected and logic result since JIBS is the premier outlet for international business research (Dubois and Reeb, 2000; 10 Canabal and White III, 2008). JIBS and SMJ were also considered in the top list in a review of articles in mainstream management journals (Werner, 2002). In addition, only a few numbers of citations came from domestic academic journals. These were the only three domestic journals (RAUSP, RAC, and RAE) considered in the top 10 ranking of the most commonly outlet in I-BM study. Selected papers of these journals were selected in the sample of this research review and in part, these figures confirm the assumption that the three outlets generally were considered the leading academic journals in the Brazilian management area (Arkander, 2003; Tonelli et al., 2003; Vieira, 2003). 4.3.2. Most influential authors and research In order to create the list ranking the authors cited in I-BM field that are most influential, we followed the same procedures described earlier. For “total citations”, all authors received one full credit as long as its name appeared on the reference list, while for “adjusted citations” a weight measure was created according to the number of authors for each cited article. A total of 1,749 authors were cited in the 94 articles that comprise our sample. Of these authors, 477 were Brazilians and 1,287 were foreign authors. Not surprisingly, the top 2 in the ranking are foreign scholars who developed the two most commonly theories used in I-BM field. Jan Johanson was the most cited author with a total of 106 citations (adjusted citations = 52.00), following by John Dunning (adjusted citations = 47.50). Jan Johanson and Jan-Erik Vahlne (adjusted citations = 40.17) are researchers from a Nordic school who developed the called Uppsala model, while John Dunning from the University of Reading developed the Eclectic Paradigm framework at the beginning of 1980s. As previously mentioned, the most frequently authors cited in I-BM research were represented by foreign scholars (18 out 22). Only four Brazilian scholars are among the top 22 most-cited authors (i.e. Angela da Rocha, Eduardo Vasconcellos, Maria Tereza de Leme Fleury and Afonso Fleury). These authors also are the editors of five books examined in this review and the main contributors to the I-BM field. The most cited researches used in I-BM study, which was derived from 2,583 citations of 94 articles considered in this review. The ranking list also reveals the 20 top most influential research published in academic journals (9), books (8), book chapters (2), and business magazine (1). For academic journals (all international), 5 of the 9 articles were related to the Uppsala Model (Johanson and Vahlne, 1977, 1990, 2003) and Eclectic Paradigm (Dunning, 1980, 1988) models. Seven of the eight books in the top 20 were volumes authored by foreign scholar and three of these were Portuguese translations of original works. In particular, Brazilian academics were frequent in using the translated and original book of Yin (1994, 2001) as the main reference source to develop the methodology of case studies. In terms of book chapters, all of the articles were from national publications written by Brazilian scholars. 5. Conclusion I-BM research is still in an embryonic stage. Most of the research done recently has been published as multiple-authored articles. These articles were mostly produced as part of the academic advising relationship that emerges from graduate study and research. The advisors and graduate students from the University of São Paulo and the Federal University of Rio de Janeiro, which are the top two ranked institutions in terms of published studies in this field, are responsible for almost 40% of the research published in the three data sources examined in this study. Case studies have been the most commonly used methodology in I-BM research. Surveys were employed in a few cases, but based on samples of 25 or less companies. There are only a few articles that have performed statistical analysis. The Uppsala model has been the most used theoretical approach employed in I-BM research that is twice the amount of the second most applied theory which is the OLI model. But independently of the theoretical 11 approach employed by Brazilian scholars, their research interest on a particular firm seems to be positively related to the size of the company and the degree of its internationalization process. Although the international spread of Brazilian multinationals has been concentrated in resource-based activities, it should be noted that some authors have investigated companies in the medium-to high-technology sectors. In this study, we have reviewed 94 articles citing a total of 2,583 articles written by 1,749 different authors: 477 Brazilians and 1,287 foreign authors. Our analysis shows that a large number of citations are referencing studies produced by foreign scholars. Not surprisingly, the top 3 authors that are cited in the ranking are foreign authors who have developed the two most commonly theories used in I-BM field. We conclude that this shows that Brazilian authors have based their research to explain the internationalization of Brazilian multinationals on theoretical approaches and models developed in other countries. This could imply that Brazilian authors are not isolated to their own environment and are intensively learning from foreign counterparts. However, while I-BM scholars may be aware of what has been done and published in the international business literature, they have also largely focused on describing and replicating foreign approaches. This research review has identified some important generalized findings on the scope and nature of I-BM research. In addition, the results provide some valuable insights for the types of research activities that should be prioritized in the medium-term. There has been a limited application of theoretical approaches and research methods in I-BM field. In order to build a stronger core of research and to undertaken more rigorous hypothesis testing, multi-case studies and the analysis of larger samples of companies should be priorities in the study of the internationalization of Brazilian multinationals. As remains a challenge in Brazil more generally, research efforts are also institutionally and regionally concentrated. The decentralization of scholarship to include a larger group of scholars and researchers and institutions from the Middle East and Northeast regions of Brazil in the research effort of I-BM could greatly enrich discussions by incorporating experiences of lesser known researchers in these areas. Finally, it should be noted that there are insignificant numbers of Brazilian research papers that have been published in international outlets. We believe that improving this percentage should be an obvious and reasonable goal for Brazilians researchers in the I-BM research field. “Internationalization” should not be restricted to the research topic investigated by Brazilian authors and also applied to the diffusion of this knowledge so it can be shared with the international academy. Our results also show that there is a need for increasing the number of publications by national scholars in international peer-reviewed journals with a high impact factor. For I-BM research to contribute significantly to the international business literature, it must strive to attain an internationalization of its academic production. 6. References ALMEIDA, A.
