Proceedings of 28th International Business Research Conference 8 - 9 September 2014, Novotel Barcelona City Hotel, Barcelona, Spain, ISBN: 978-1-922069-60-3 Trade Network and Cultural Distance in Cross-border Acquisitions: An Empirical Analysis with U.S. Acquiring Firms Seung Hun Han* and Eun Jin Jo** We examine trade networks and cultural distance in cross-border acquisitions. Using a sample of 938 cross-border acquisitions during 2000-2007, we found that cultural distance between acquiring nation and target nation negatively affects the post-performance of cross-border acquisitions. We mainly used the Greet Hofstede cultural distance score as the cultural distance proxy. We also measured the cross-national relationship with eigenvector centrality by using trade volume data. We found that acquisitions with stronger centrality give the higher abnormal return to acquiring firms. We conclude that the trade network measured by eigenvector centrality explains better the performance of acquiring firms than cultural distance measurement. JEL Codes: G34, G15 1. Introduction In recent decades, the trend in world economy is characterized by liberalization through deregulation and consequently the financial markets are globalized and opened to other countries(Helleiner 1995). Thus, not only financial markets but also product markets are integrated. In other words, through the world market globalization both the real economy (i.e., trade) and the financial economy (i.e., financial transactions) are integrated(Vo and Daly 2007). Accordingly, cross-border M&A’s have been increasing significantly and many previous literatures document the increasing trend of the cross-border acquisitions in terms of volume and frequency. Even though the global markets are integrated and cross-border acquisitions are prevalent in global markets, still there exist various variations in terms of both country-specific factors (i.e., culture, religion, language) and dealspecific components (i.e., payment methods) between the target nation and acquiring nations(Ahern, Daminelli et al. , Morosini, Shane et al. 1998, Rossi and Volpin 2004, Chakrabarti, Gupta-Mukherjee et al. 2008, Aybar and Ficici 2009). Therefore, in this study, we examine the impact of national trade connectivity using complex network analysis on the performance of cross-border acquisitions of the US firms. Studies in cross-border mergers and acquisitions, bilateral relationship such as cultural distance or trade openness has been the focus of successful transactions between target and acquiring nations. Because acquisition with target nations having stronger power in international connectivity or trade network may allow managers of acquiring firms to reinforce the efficiency of the post-merger integration process (Chakrabarti, Gupta-Mukherjee et al. 2008), investigating relationship between target and acquiring nations in international trade network contexts can provide valuable * Seung Hun Han, Business and Technology Management, Korea Advanced Institute of Science and Technology, Republic of Korea, Email: synosia@kaist.ac.kr ** Eun Jin Jo, Business and Technology Management, Korea Advanced Institute of Science and Technology, Republic of Korea, Email: eunjin.jo@kaist.ac.kr Proceedings of 28th International Business Research Conference 8 - 9 September 2014, Novotel Barcelona City Hotel, Barcelona, Spain, ISBN: 978-1-922069-60-3 insight in understanding the determinants of cross-border acquisitions returns. In addition to that, acquisitions with target nation which is more open to world trade can give a chance in global market expansions for acquiring companies. A few studies introduce the bilateral trade concepts in cross-border mergers and acquisitions research by using export and import trade volume data, and they empirically show positive and significant relationship between M&As performance and bilateral trade between target and acquiring nations (Rossi and Volpin 2004, Chakrabarti, GuptaMukherjee et al. 2008). However, the bilateral trade openness has a few limitations since they do not consider the complexity in world trade contexts. In other words, the trade openness measurement should be more than bilateral, because world economy is getting more integrated and more interconnected through globalizations. Long before financial research begins to focus on bilateral trade, studies regarding the international trade have been investigated in economics and social networks. De Benedictis and Tajoli (2011) argue that world trade should be considered as network and analyzed with various network analysis measurements such as closeness, betweenness centralities. Likewise, adopting a network analysis can complement bilateral relationship simply measured by trade volume from target to acquiring nations. Therefore, we use eigenvector centrality which is one of the most popular methods in social network filed instead of bilateral trade variables. In addition to trade network, we also focus on cultural distance between target and acquiring nations, because the cultural disparity has been the most popular variable in recent cross-border M&A studies(Ahammad, Tarba et al. , Chakrabarti, GuptaMukherjee et al. 2008, Reus and Lamont 2009, Erel, Liao et al. 2012). Studies in cultural distance empirically show the significant relationship with M&A performance. However, there are also a few controversies whether cultural factors positively or negatively affect the M&A returns. Some researches show the positive relationship between cultural difference and post-performance returns since cultural disparity can provide a variety of routines and repertories (Morosini, Shane et al. 1998, Chakrabarti, Gupta-Mukherjee et al. 2008). However, there are also contradicting results. Since cultural distance can be a cost for acquiring companies in post integration process and cause cultural clashes, cultural distance is negatively related with short-term performance of cross-border M&A (Datta and Puia 1995, Stahl and Voigt 2008). In this research, we focus on short-term performance with two days period window and Pragmatic versus Normative(PRA) and Indulgence versus Restraint (IND) which have not studied in previous studies). In addition, Stulz and Williamson (2003) argue that countries can stand to benefit from the bilateral trade, and it is important to consider not only cultural effect but impact from other countries. So this examine the moderating effect of openness measured by trade network with cultural distance. Therefore, this study hypothesizes the negative relationships between cultural distance and acquisition performance and moderating effect of trade network. In this research, we use the 909 acquisitions from 43 different target nations and U.S. acquiring firms during 2000-2007. With the event study methodology and network analysis measurements, we investigate the impact of centrality in world trade network and cultural distance measured by Greet Hofstede on the performance of M&As and control for firm specific factors such as firm size, profitability, and financial leverage. We find that acquisitions with target nations having more centrality in Proceedings of 28th International Business Research Conference 8 - 9 September 2014, Novotel Barcelona City Hotel, Barcelona, Spain, ISBN: 978-1-922069-60-3 cross-border trade network give higher returns for acquiring companies. This result strongly supports our hypothesis and consistently significant after adding the cultural distance variables and controlling firm specific variables and deal specific variables. Also, our empirical evidence shows that cultural distance variables are negatively related with performance of M&As. These results are consistent with previous literatures which short-term performance of cross-border acquisitions is negatively related with cultural distance due to cultural clashes (Datta and Puia 1995). We contribute to the previous literatures with introduction of network analysis in financial studies, which are more elaborated measurements for bilateral trade. Also we capture trade relationship between target and acquiring nation in the contexts of world trade network rather than simple bilateral transactions. In addition, we confirm the negative effect of cultural distance in short-term returns of cross-border acquisitions with Hofstede measurements. In cultural distance measurements, we use six-dimensional distances rather than four-dimensional measurements which widely-adopted in previous literatures. The rest of the paper is organized as follows. The next section describes the previous literatures. Next section presents the sample selection and applied methodologies. This is followed by a discussion of the effect of trade network and cultural distance to post performance of cross-border acquisitions. This paper concludes with summarized results and several suggestions for the future research in this area. 2. Literature Review and Hypothesis Development Since early 1990, the international mergers and acquisitions (M&As) begin to prosper along with the increase in economic globalization (Martynova and Renneboog 2008). Since domestic transactions are dominated in M&As market up till then, the globalization of M&A is the most striking features in recent M&As studies. Unlike domestic deals, international deals give an important way for multinational companies to achieve global market power. Yet, there are some studies examining the determinants of cross-border takeover gains in bidder and target firms. In addition to the various factors which affecting the M&As performance such as firm specific or deal specific factors, cultural distance between acquirer and target firms come to the fore in recent literature(Ahern, Daminelli et al. , Morosini, Shane et al. 1998, Rossi and Volpin 2004, Chakrabarti, Gupta-Mukherjee et al. 2008, Aybar and Ficici 2009). A substantive theory and research examining the determinants of success in crossborder mergers and acquisitions have done for the past few decades, however, there does not exist deterministic conclusions in this area. Also, cultural difference between two parties in M&As is the focus of international studies. Although many recent studies already discuss the effects of cultural disparity on the cross-border M&As returns, there are some controversial or contentious about this issue. Morosini, Shane et al. (1998) posit both positive and negative effect of cultural distance on cross-border acquisitions since cultural distance has both synergy and disruption to the acquirers And they empirically prove that cultural distance affects positively to the percentage of sales growth of acquiring firms since cultural distance provides variety of patterns and methods. However, this literature has limitations in using percentage of sales growth as dependent variable to show performance of the acquiring Proceedings of 28th International Business Research Conference 8 - 9 September 2014, Novotel Barcelona City Hotel, Barcelona, Spain, ISBN: 978-1-922069-60-3 company (Morosini, Shane et al. 1998). Also, more recent literature show that acquisitions with more culturally dispersed give higher returns in the long-term perspectives(Chakrabarti, Gupta-Mukherjee et al. 2008). On the other hand, some studies argue that cultural distance can affect negatively to the shareholders’ return of acquiring firms since cultural distance can be cost to the acquiring firms and there is also cultural risk in post-acquisition process(Ahern, Daminelli et al. ,Stahl and Voigt 2008). Also, Datta and Puia (1995) prove that negative side of cultural fitness on shareholders in cross-border acquisitions with the acquisitions undertaken by the U.S. acquirers. Since this study focus on announcement effect rather than long-term performance, they have a contribution to the previous literature. 𝐻1 : Cultural distance negatively affects returns of acquiring firms in cross-border acquisitions. As well as cultural difference measured by Hofstede (1984), other cultural factors such as language and religion are viewed as important variables in international finance studies (Ahern, Daminelli et al. , Stulz and Williamson 2003, Rossi and Volpin 2004, Chakrabarti, Gupta-Mukherjee et al. 2008). Stulz and Williamson (2003) argue that language can be a tool for communication and promote transferring the ideas among employees, so language plays a role in international acquisitions. Likewise, religion can be a route for innovation and plays a key role in finance (Stulz and Williamson 2003). Also other literature empirically shows that same language between two acquisition partners positively affects the propensity for cross-border acquisitions rather than domestic deals (Rossi and Volpin 2004). Therefore, language and religion can play a crucial role in cross-border mergers and acquisitions since these two factors affect values, resources allocation, institutions in a country (Stulz and Williamson 2003). 𝐻2 : Same language and religion are positively related with takeover returns in crossborder acquisitions. In addition to the cultural indexes, national economic factors can be critical factor for cross-border acquisitions since cross-border acquisitions are an important way for gaining international market power. Therefore, recent studies start to focus on economic difference between acquirer nation and target nation and openness of target nation to international trade market (Rossi and Volpin 2004, Chakrabarti, Gupta-Mukherjee et al. 2008). Rossi and Volpin (2004) show that the bilateral trade between two acquisition parties positively and significantly affects the propensity for cross-border deals. Although it gives reverse results for bilateral trade variables, Chakrabarti, Gupta-Mukherjee et al. (2008) prove that openness of target nation to international trade is also crucial part in cross-border acquisitions studies. Researchers in international economic studies consider international trade as a network structure for a long time (De Benedictis and Tajoli 2011). However, the methodology which they adopted does not consider international trade as network and does not capture the complexity of whole international trade network. Rather than adopting previous measurement, social network analysis can be a proper measurement for examining the international trade network. Since centrality, one of well-kwon methodology in network analysis, can capture the positions of a Proceedings of 28th International Business Research Conference 8 - 9 September 2014, Novotel Barcelona City Hotel, Barcelona, Spain, ISBN: 978-1-922069-60-3 node in the network structure. Social network methodology rapidly rises as tool for measuring complex relationships in broad areas in research such as marketing, economics (De Benedictis and Tajoli 2011, Yoganarasimhan 2012). Yoganarasimhan (2012) examines the positions of the writers in local network with connectivity, clustering, and centrality which are well-adopted tools in social network analysis. De Benedictis and Tajoli (2011) explore the world trade network with centrality measurement. They argue that utilization of centrality measurements can appropriately make up for other empirical tools in measuring the world trade network (De Benedictis and Tajoli 2011). 𝐻3 : Acquisitions with target nations having stronger power in international bilateral network give higher returns for acquiring companies. 3. Data and Methodology Our empirical analysis of cross-border acquisitions is based on the sample occurred during 7-year period, 2001-2007. The acquisitions data is obtained from the SDC Platinum Mergers & Acquisitions database. Firstly, we get 8,767 observations from the U.S. acquirers excluding the targets or acquirers which industry sector is financial industry. From that, we select events with several steps. The sample selection criteria used in this paper are 1) acquirer is publicly traded; 2) the deal is completed; 3) target and acquiring nations have Hofstede cultural distance score; 4) target or acquirer industry is not utility industry, SIC codes from 4900-4999; 5) the acquirer owns 100% shares of target firms after transaction; and 6) non-U.S. target nations; 7) target nations have trade volume data. Finally, we have 899 samples with the U.S. acquirer nation from 42 different target nations. Table 1 shows the number of transactions for each target nations during 2001-2007. The majority of acquisitions with the United States as the acquirer are made by the top two target nations, United Kingdom and Canada. Proceedings of 28th International Business Research Conference 8 - 9 September 2014, Novotel Barcelona City Hotel, Barcelona, Spain, ISBN: 978-1-922069-60-3 Table 1 Breakdown of sample of target nations which conducted cross-border acquisitions during 2000-2007 Target nations No. of acquisitions United Kingdom 199 Canada 182 Germany 96 France 66 Australia 50 China 41 Netherlands 32 Italy 21 Switzerland 21 Mexico 18 Sweden 16 Brazil 15 Norway 13 Belgium 12 Spain 12 India 11 South Korea 10 Others 84 Total 899 We mainly use the ‘Eventus’ methodology for the event study to observe the stock price reaction to the announcement of acquisitions. This approach is widely used in finance research when seeing the returns of certain events, such as mergers and acquisitions, stock repurchase, stock split, and so on. Under the market-adjusted returns (MAR) model, we get the cumulative abnormal returns (CARs) of acquirer firms. Abnormal returns (AR) are computed by the subtracting the market index return for day t from the rate of return of j company at time t. As a result, the abnormal return of company i at time t is given by AR i,t = R i,t − R m,t (1) Cumulative abnormal returns (CARs) for window (𝑡1 , 𝑡2 ) is given by t2 CARsi (t1, t 2 ) = ∑T=t AR i,t 1 (2) We construct five windows, (-5, +5), (-3, +3), (-1, +1), (-1, 0), (0, +1) for cumulative abnormal returns (CARs) where t=0 is announcement date. We mainly use the CARs (-1, 0) as the dependent variable for multivariate regression models in this study. Deal specific characteristics are likely to affect the performance of acquiring firms. Therefore, deal specific variables are added in our regression models as independent dummy variables. From the SDC Platinum database, we also obtain deal specific variables regarding the deal type. With this information, we construct the dummy variable as friendly, hostile, and neutral. In our regression models, hostile equals one if the transaction is the hostile deal. Proceedings of 28th International Business Research Conference 8 - 9 September 2014, Novotel Barcelona City Hotel, Barcelona, Spain, ISBN: 978-1-922069-60-3 In addition to that, firm-level variables also have an impact on the acquisition returns and should be controlled to illuminate the impact of other major variables, such as network centrality and cultural factors. Therefore, we use three variables to control the firm specific characteristics such as firm size, financial leverage, and profitability. Required data are obtained from COMPUSTAT database. LN(Total asset) is the natural logarithm of total asset as proxy for firm size. Leverage is the debt ratio calculated as total debt divided by total asset as proxy for financial leverage. ROA is the return on asset (ROA) calculated as net income divided by total assets. In recent studies, cultural factors have been viewed as key factors determining the success of cross-border mergers and acquisitions. Therefore, we examine the cultural factors with several variables. Firstly, we use the cultural distance developed by Greet Hofstede (1980, 2001, 2010). They observe cultural disparity with sixdimensional factors, power distance index (PDI), individualism versus collectivism (IDV), masculinity versus femininity (MAS), and uncertainty avoidance (UAI), pragmatic versus normative (PRA), and indulgence versus restraint (IND). Each variable is calculated as the absolute difference between target and acquiring nations. To capture the impact of each variable, we run the regression with six variables separately. Also, we investigate the overall influence of cultural disparity with formula (3) (Morosini, Shane et al. 1998). In our regression model, we use the natural logarithm of aggregate cultural distance as ‘LN(Aggregate Cultural distance)’ to see the combined influence of Hofstede’s cultural distance. 6 Aggregate CD (T, U) = √∑(𝐻𝑖,𝑡 − 𝐻𝑖,𝑢 ) 2 (3) 𝑖=1 On the other hand, we also investigate the impact of language and religion on the acquisitions gains. We construct the language dummy variable which given score 1 if the target and acquiring nations share same the first language, and 0 otherwise. Also, we construct the religion dummy variable which given score 1 if the target and acquiring nations share the same primary religion, and 0 otherwise. All the data required is obtained from CIA World Fact Book. In recent international M&A studies, trade relationship between two acquisition parties measured by bilateral trade emerges as important factor (Rossi and Volpin 2004, Chakrabarti, Gupta-Mukherjee et al. 2008). With this trend, we also observe the international trade network. Besides countries’ own properties, network analysis investigates the relationship between countries and also gives emphasis on the power of flow in the bilateral trade (De Benedictis and Tajoli 2011). De Benedictis and Tajoli (2011) argue that the bilateral trade should be investigated as network and gives more priority on the interconnectedness rather than on countries’ attributes. Therefore, they analyze world trade network with network analysis such as degree, closeness, and betweenness centralities. In previous literature, degree, closeness, and betweenness centralities are widelyused in network analysis (De Benedictis and Tajoli 2011, Yoganarasimhan 2012). Centrality measurements used in the existing literature also have limitations that they are only useful in rigorously binary connections between nodes (Bonacich 2007). Different from those measurements, eigenvector centrality gives weights differently Proceedings of 28th International Business Research Conference 8 - 9 September 2014, Novotel Barcelona City Hotel, Barcelona, Spain, ISBN: 978-1-922069-60-3 depending on their centralities (Bonacich 1972). Eigenvectors, and Bonacich’s c(β) gives advanced measures with the power measurements in complex networks (Bonacich 2007). Therefore, we use eigenvectors, and Bonacich’s c(β) to investigate the world trade network. The centrality power of target nation in bilateral trade network can affect the acquisitions’ returns, we therefore measure centrality of target nations with eigenvectors, and Bonacich’s c(β). In this study, we only use annual bilateral ‘export’ volume data of 42 nations measured in US dollars from World Bank database. Although target nations are only 42 nations in this study, we collect all the data provided to capture the target nation’s centrality in entire world trade network. According to Bonacich (2007), eigenvector centrality, ‘x’ can be shown as two ways. One is defined as matrix form and the other is calculated as sum of path. In matrix form, λ is defined as the largest eigenvalue of A and ‘n’ is defined as the number of nodes or the number of nations in this research. And in the right equation, 𝑎𝑖𝑗 equals 1 if node i is connected to the node j, and 0 otherwise. Ax = λx, λ𝑥𝑖 = ∑𝑛𝑗=1 𝑎𝑖𝑗 ∙ 𝑥𝑗 , 𝑖 = 1, ⋯ , 𝑛 (4) According to the formula (4), we get the value of centralities for each year. In regression model, the eigenvector centrality of target nation is represented as ‘Centrality’ and used as major determinants to explain the determinants of takeover returns. Table 3 shows target nations’ eigenvector centralities in the world trade network, ranked in descending and ascending order for each year. In table 3, the order is fluctuating from year to year. And also, we add other economic variables such as gross domestic product (GDP) and growth rate of gross domestic product (GDP Growth). These variables are obtained from the World Bank database, and we use natural logarithm of GDP for this study, LN(GDP). In Table 3, we construct the descriptive statistics for dependent variables and control variables. First part of the table 3 shows the explanatory variables regarding the Hofstede’s cultural distance, and second part shows the explanatory variables such as openness using trade volume data, economic data, and last part shows the firm specific, control variables.

Empirical Results In this study, we use the CARs to measure the short-term performance of acquiring firms. Since we focus on announcement effect, we collect five windows for this event study on the basis of the announcement date. Five windows are CARs (-1, 0), CARs (0, +1), CARs (-1, +1), CARs (-3, +3), and CARs (-5, +5). Among them, we mainly use the one-day window from a day before and the event day, CARs (-1, 0). Since there can be information linkage in equity market, we can observe the abnormal returns of acquiring firms with observation period from one day before event day to event day(Chen and Young 2010). Table 4 shows the descriptive statistics of CARs (1,0) of acquiring firms. Although literature focusing on long-term performance of acquiring firms shows negative returns (Chakrabarti, Gupta-Mukherjee et al. 2008), we observe the positive abnormal returns. In this study, we use multiple linear regression models to test the impact of crossnational trade network and cultural distance to the performance of acquirers. Since we capture the heteroskedasticity in our models, we perform OLS regression with White’s MacKinnon and White (1985)’s heteroscedasticity consistent standard errors for both Table 5 and Table 6. In Table 4, we show the results of our regression models with independent variables and control variables. The dependent variable is CARs obtained from event study methodologies explained in above section. The main independent variables in this study are trade network centrality and several cultural factors. Also we use several variables to control the firm specific characteristics. The control variables are firm size (Natural logarithm of total asset), financial leverage (Debt ratio), and profitability (ROA).

The dependent variable in these models is CARs (-1, 0). The first model contains only centrality measurement as explanatory variable and do not include control variables. Although we do not control any firm specific variables, first model shows that trade network is positive and statistically significant at 1 % level. This result does not change even after controlling the firm specific variables. In Table 5, model (3), we include six-dimensional Hofstede’s cultural measurements. In this model, only one cultural distance factor, MAS, shows significant results and centrality is significant at 5% level. The trade network centrality shows consistent results in three models with cultural factors and firm specific characteristics considered. This result indicates that acquisitions with target nations having stronger power in trade network give higher returns in the short-term period. Since cultural distance might be related with each other, we run the regression separately with six different cultural dimensions in model (4) to (9) in Table 5. Among six different cultrual distnace measures, only one variale show statistical significance. The coefficient of MAS (Masculinity versus Femininity) is negative and significant at 5% level. Throughout the six models from (4) to (9), the Hofstede measurements are consistently negative to the acquring firm’s performance. Although other cultrual distance variables do not show significant results, results are consistent with previous literatures supporting that cultural distance can be a cost for an acquiring company and it gives negative effect on the returns of acquiring firms in the short run period (Ahern, Daminelli et al. , Chakrabarti, Gupta-Mukherjee et al. 2008).

Therefore, language and religion should be examined when exploring the cross-border researches. We include language and religion dummy variables in model (10) and (11) respectively. Language dummy variable does not show significant results, in model (10). However, Religion dummy variable is positive and significant at 10% level. This result indicates that acquisitions with target nations which the majority of people believe same religion with acquiring nation perform better in the short-run. In this case, target nations whose first religion is the Christian give higher returns. These results are consistent with the previous researches (Rossi and Volpin 2004, Chakrabarti, Gupta-Mukherjee et al. 2008). We analyze the effect of trade network, economic factors, deal-specific variable and cultural factors with ten models. Because of heteroskedasticity, we use same regression model with Table 5. In Table 6, we also mainly use CAR (-1, 0) to capture the meaningful factors affecting acquisitions’ returns. In model (1), we only run the regression with centrality variable and control variables. It shows that centrality significantly affects the acquisitions’ returns at 5% significance level. From the model (2) to (8), we add the hostile dummy variable and religion dummy variable. Hostile variable is negative and significant at 5% level, which means that hostile takeover negatively affects the returns after acquisitions. Therefore, takeovers which accomplished without agreement from the target company do not positively affect the post-acquisition performance. Also, religion dummy variable is positive and significant at 10% level in model (2) and (3), which means acquisitions which sharing same primary religion positively affects the abnormal returns of the acquirers. LN(GDP) variable is positive and significant throughout the eight models from model (4) to (11), which means acquisitions with target nations having larger GDP, or economic power gives positive affects to the acquisitions. And also, LN(Aggregate Cultural distance) variable is negative and significant in four models from (6) to (11) except model (8), this results are consistent with the previous studies (Ahern, Daminelli et al. , Chakrabarti, Gupta-Mukherjee et al. 2008). 5. Conclusion Previous studies argue that cultural distance can affect negatively to the acquiring firms since cultural distance is a cost for acquirers to integrate with target companies. Therefore, we hypothesize that cultural distance can affect negatively to the postacquisitions returns of acquiring companies. To test this hypothesis, we use a multiple-regression models and event study methodology with cultural distance variables developed by Greet Hofstede. In addition to that, economic variables which measure the openness of target nation with trade volume data and gross domestic nation (GDP) are focused on previously. Instead of using openness measurement suggested by previous literature, we apply the network analysis methodology with trade volume data. We expect that cross-national relationships measured by network measurement, eigenvector-centrality can explain better in cross-border acquisitions. Therefore, we add a centrality variable as main explanatory variable for this paper. And, we confirm that acquisitions with target nation which is more open to international trade network show positive and higher returns to the acquiring firms. 14 Proceedings of 28th International Business Research Conference 8 - 9 September 2014, Novotel Barcelona City Hotel, Barcelona, Spain, ISBN: 978-1-922069-60-3 We extend the cross-border merger and acquisitions literature on the role of crossnational trade network. We focus on the cross-relationships between acquiring and target nations whereas previous literature only focus on the openness to the international trade market of acquiring firms. Also, we confirm the cultural distance negatively affects the short-term returns of acquiring firms. However, further study is needed to explore the determinants of cross-border mergers and acquisitions by adopting other network methodologies. And also, we only gather the export volume data only. So, analyzing trade network with both export and import data is needed in future research. References Ahammad, M. F., et al. 2014.
