group lending repayment incentives and social collateral abstract in this paper we investigate the impact on repayment rates of lending to groups which are made jointly liable for repayment this type of scheme especially in the guise of the grameen bank in bangladesh has received increasing attention we set up and analyze the repayment game which group lending gives rise to our analysis suggests that such schemes have both positive and negative effects on repayment rates the positive effect is that successful group members may have an incentive to repay the loans of group members whose projects have yielded insufficient return to make repayment worthwhile the negative effect arises when the whole group defaults even when some members would have repaid under individual lending we also show how group lending may harness social collateral which serves to mitigate its negative effect

do we really need more entry mode studies this commentary s title is not meant to be a rhetorical question in congratulating brouthers 2002 for the jibs decade award we have an opportunity to assess where we are within this field of inquiry and what is our trajectory i believe that we have accomplished a lot in this area of study nevertheless i am concerned about its current trajectory so much so that i think we should seriously question whether we need more entry mode studies especially if we are going to get more of the same

union membership and employment dynamics with endogenous union density abstract based upon an intertemporal optimizing model of trade unions this paper proposes a plausible union density function and examines the relative level of employment between the intertemporal model and the conventional static model we find that endogenizing union density provides an incentive for the union that is concerned about its future membership level to hire a lower level of employment this opens the way to obtain the result that employment is lower in the intertemporal model than in the conventional static model we also find that the equilibrium employment level may not display a positive linkage with union membership after endogenizing union density

learning across geographic space pro market reforms multinationalization strategy and profitability building on economic geography and knowledge based theory i argue that pro market reforms augment the profitability of firms by increasing their competitiveness and market knowledge however i propose that this effect is greater for firms that operate internationally firms that operate in more advanced markets and firms that become multinationals before reforms are implemented this is because such firms acquire market knowledge abroad that they can use when responding to reforms at home giving them a head start advantage over other local firms the analyses of a panel of the largest 500 latin american companies from 1989 to 2008 provide support for these arguments

from the editors common method variance in international business research jibs receives many manuscripts that report findings from analyzing survey data based on same respondent replies this can be problematic since same respondent studies can suffer from common method variance cmv currently authors who submit manuscripts to jibs that appear to suffer from cmv are asked to perform validity checks and resubmit their manuscripts this letter from the editors is designed to outline the current state of best practice for handling cmv in international business research

capabilities as a mediator linking resources and the international performance of entrepreneurial firms in an emerging economy this study investigates an under researched topic the relationships between capabilities resources and international performance among entrepreneurial firms in an emerging economy we combine the resource based view of the firm and the capability building perspective of rent creation to shed light on the crucial role of firm specific capabilities that transform key resources into performance outcomes employing a large sample of chinese entrepreneurial firms our investigation demonstrates that while the resources of institutional capital and managerial ties are important in the internationalization effort their effects on international performance are channeled through each firm s adaptive capability this adaptive capability is the firm s ability to coordinate recombine and allocate resources to meet the different requirements of foreign markets specifically our research is able to demonstrate support for the mediating role of capabilities in the relationship between resources and international performance the implications of these findings for theoretical development and future research are discussed

asset specificity and foreign market entry mode choice of small and medium sized enterprises the moderating influence of knowledge safeguards and institutional safeguards according to transaction cost economics tce reasoning firms choose equity as opposed to non equity foreign market entry modes to safeguard specific assets the present paper contextualizes the well researched relationship between asset specificity and foreign market entry mode choice by introducing knowledge safeguards international experience host country networks and imitation and institutional safeguards property rights protection and cultural proximity as alternative mechanisms for securing a firm s specific assets testing our hypotheses on a sample of 206 small and medium sized enterprises we find that knowledge safeguards and institutional safeguards weaken the effect of asset specificity on the choice of equity foreign market entry modes contextualizing the relationship between asset specificity and foreign market entry mode choice helps to enhance our understanding of the scope conditions of tce based entry mode studies and beyond

the experience factor in foreign market entry behavior of service firms the paper examines the effect of international experience on service firms selection of foreign markets and entry modes the investigation utilizes survey date from 151 united states based service firms results on market selection suggest that as their experience increases and becomes geographically more diversified service firms tend to choose markets that are culturally less similar to their home country on entry mode choice the paper departs from traditional linear conceptualizations and hypothesizes a u shaped relationship between experience and propensity for integrated entry modes results generally support the hypothesis the paper explains these findings and describes how service firms resemble and differ from manufacturing firms in their foreign market entry behavior

host country corruption and the organization of hq subsidiary relationships multinational enterprises mnes operating in more corrupt host than home countries face actual costs related to processing information for decision making and lack of local legitimacy and potential reputation and legal costs in case of corruption scandals drawing on the organizational perspective of corruption we argue that greater subsidiary autonomy helps minimize these costs however headquarter hq subsidiary communication weakens the autonomy based advantages for minimizing legitimacy costs and mnes experience in relatively corrupt countries weakens the advantages for minimizing information processing costs our analysis of 261 italian foreign subsidiaries in 25 host countries confirms most of our arguments except the moderating effect of mne experience our findings contribute to research on corruption and fdi weak institutional contexts and mne strategies as well as the literature on hq subsidiary relationship

can social cohesion be harnessed to repair market failures evidence from group lending in guatemala the success of group lending in developing countries has been attributed to the ability of the institution to mitigate asymmetric information problems in credit markets previous research has offered a number of explanations for this phenomenon social ties between borrowing group members internal group pressure to repay loans and peer monitoring this research presents empirical tests on borrowing group data from guatemala which indicate that peer monitoring significantly effects borrowing group performance through stimulating intra group insurance group pressure is found to have a small effect in deterring moral hazard while the effect of social ties among members is statistically insignificant

extending the internationalization process model increases and decreases of mne commitment in emerging economies the internationalization process model suggests that firms internationalize by building positions in foreign markets and networks following iterative cycles of learning and changes in commitment however as subsidiaries evolve commitments may be decreased as well as increased a phenomenon that has rarely been studied moreover it remains an open question why strategic intentions at the outset of an investment project differ from the actual operations established we address these questions by extending the model and combining it with mintzberg and waters framework of strategy formation specifically we suggest that commitment decisions correspond to statements of intended strategy while network positions correspond to realized strategies the processes of learning opportunity creation and trust building triggered by commitment decisions are however moderated by institutional influences that lead to divergences between realized and intended strategies we test propositions derived from this framework on a survey data set of subsidiaries of multinational enterprises in hungary lithuania and poland and find that institutional voids and institutional uncertainty affect subsidiary strategy implementation but in opposing directions under high institutional uncertainty investors prefer low commitment but flexible modes that enable later commitment increases whereas institutional voids increase up front information search and adaptation costs that reduce the likelihood of early post entry adjustments our analysis reinforces the need for more differentiated theoretical analyses of how institutions affect business strategies over time

institutions transaction costs and entry mode choice in eastern europe the process of change from a centrally planned system to a market economy generates an institutional framework that is only partially reformed and therefore inconsistent and unstable this leads to high transaction costs for economic agents multinational enterprises entering transition countries have to adapt their strategies to the local institutions and reduce exposure to highly imperfect markets this paper analyzes how the costs of organizing business in transition environments influence entry mode choice the empirical results show that host country institutions in transition economies have an impact on the choice of entry modes moreover different mechanisms determine the internalization of managerial and technological knowledge

the construct of institutional distance through the lens of different institutional perspectives review analysis and recommendations this paper presents a review and critique of the 20 year old literature on institutional distance which has greatly proliferated we start with a discussion of the three institutional perspectives that have served as a theoretical foundation for this construct organizational institutionalism institutional economics and comparative institutionalism we use this as an organizing framework to describe the different ways in which institutional distance has been conceptualized and measured and to analyze the most common organizational outcomes that have been linked to institutional distance as well as the proposed explanatory mechanisms of those effects we substantiate our qualitative review with a meta analysis which synthesizes the main findings in this area of research building on our review and previous critical work we note key ambiguities in the institutional distance literature related to underlying theoretical perspectives and associated mechanisms distance versus profile effects and measurement we conclude with actionable recommendations for improving institutional distance research

group versus individual liability short and long term evidence from philippine microcredit lending groups abstract group liability in microcredit purports to improve repayment rates through peer screening monitoring and enforcement however it may create excessive pressure and discourage reliable clients from borrowing two randomized trials tested the overall effect as well as specific mechanisms the first removed group liability from pre existing groups and the second randomly assigned villages to either group or individual liability loans in both groups still held weekly meetings we find no increase in short run or long run default and larger groups after three years in pre existing areas and no change in default but fewer groups created after two years in the expansion areas

the microfinance promise in the past decade microfinance programs have demonstrated that it is possible to lend to low income households while maintaining high repayment rates even without requiring collateral the programs promise a revolution in approaches to alleviating poverty and spreading financial services and millions of poor households are served globally a growing body of economic theory demonstrates how new contractual forms offer a key to microfinance success particularly the use of group lending contracts with joint liability for the most part however high repayment rates have not translated into profits and studies of impacts on poverty yield a mixed picture in describing emerging tensions the paper highlights the diversity of innovative mechanisms beyond group lending contracts the measurement of financial sustainability the estimation of economic and social impacts the costs and benefits of subsidization and the potential to reduce poverty through savings programs rather than just credit the promise of microfinance has pushed far ahead of the evidence and an agenda is put forward for addressing critical empirical gaps and sharpening the terms of policy discussion

decision specific experience in foreign ownership and establishment strategies evidence from japanese firms in this paper we examine the importance of decision specific experience for a multinational firm s foreign ownership structure and establishment mode decisions a unique procedure to measure the decision specific experience construct is developed based on data for the period 1969 1991 we find strong empirical evidence from experiences of japanese firms to support the hypotheses that firms tend to select ownership structures and establishment modes based on their experiences with similar ownership structures and establishment modes in the past

entry mode deviation a behavioral approach to internalization theory we explore when and why decision makers choose international entry modes e g hierarchies or markets that deviate from internalization theory s predictions by applying a cognitive perspective on entry mode decision making we propose that the performance of prior international activities influences decision makers behavior in different ways than assumed in internalization theory more specifically due to a representativeness bias underperforming overperforming past ventures influence the decision to change continue using the previous entry mode choice which may result in an entry mode deviation in addition the propensity to deviate from theoretical predictions is stronger when the experience is recent and or salient due to an availability bias in conclusion we argue that internalization theory can benefit from incorporating more systematically important behavioral assumptions on how firms enter international markets in so doing we contribute to the recent conversation on how variations in human behavior influence internalization theory

legitimacy and multi level institutional environments implications for foreign subsidiary ownership structure in this study we examine from an institutional perspective the legitimacy rationale behind the choice of subsidiary ownership structure among multinational corporations mncs we suggest that when under a strong pressure to conform at the host country and local industry levels of their institutional environment mncs are likely to take a lower ownership stake in exchange for external legitimacy in the host country or local industry that their foreign subsidiaries are entering we also suggest that mncs are likely to take a higher ownership stake in response to strong internal pressure to sustain their internal legitimacy at the corporate level of their institutional environment we also propose that mncs are more likely to exchange ownership for legitimacy in local industries than in host countries and in local markets with a high level of political instability than in those with a low level of political instability these propositions are generally supported by our analysis of 4451 subsidiaries established by 898 japanese mncs that operated in 39 countries across 52 industries two digit sic between 1988 and 1999

the choice between joint venture and wholly owned subsidiary an institutional perspective the study of foreign entry mode choice has been based almost exclusively on transaction cost theory this theory focuses mainly on the impacts of firm and industry specific factors on the choice of entry mode taking the effects of country specific contextual factors as constant or less important in contrast the institutional perspective emphasizes the importance of the influence of both institutional forces embedded in national environments and decision makers cognitive constraints on the founding conditions of new ventures still this theoretical perspective has yet to provide insights into how institutional factors influence the choice of foreign entry mode the primary goal of the present study is to provide a unifying theoretical framework to examine this relationship we synthesize transaction cost and institutional perspectives to analyze a sample of 364 japanese overseas subsidiaries our results support the notion that institutional theory provides incremental explanatory power of foreign entry mode choice in addition to transaction cost theory in particular we found that multinational enterprises tend to conform to the regulative settings of the host country environment the normative pressures imposed by the local people and the cognitive mindsets as bounded by counterparts and multinational enterprises own entry patterns when making foreign entry mode choices

the sacrifices of micro borrowers in ghana a customer protection perspective on measuring over indebtedness this article measures the over indebtedness of micro borrowers it defines over indebtedness from a customer protection perspective based on the borrowers sacrifices we analyse the sacrifices borrowers experience and find that 30 per cent of borrowers are over indebted we then test risk management indicators of debt problems as predictors of over indebtedness over indebtedness is strongly related to delinquency and the debt to income ratio but not to debt amounts or to multiple borrowing although our model correctly predicts 72 6 per cent of cases even the best indicators identify only a few over indebted borrowers risk management is not enough to protect customers against over indebtedness but the industry needs to measure customer experiences directly

seeking commonalities or avoiding differences re conceptualizing distance and its effects on internationalization decisions past research established distance s key influence on internationalization however theoretical issues methodological challenges and inconsistent results hinder scholarship on why distance plays such an influential role to address these problems we draw from cognitive research on similarity comparisons to re conceptualize distance and test a model of internationalization decisions analyzing the verbal protocols of executives considering a series of internationalization opportunities we demonstrate that over and above objective distance indicators considerations that reduce distance commonalities and considerations that augment distance differences have distinct effects on decisions of where when and how to internationalize as such our study contributes new insights for understanding the nature and effects of distance across different dimensions of distance and internationalization decisions moreover internationalization theories have come to emphasize different theoretical rationales for explaining the influential role of distance on different decisions by integrating these rationales together with the notion that distance reducing commonalities and distance augmenting differences have distinct implications for internationalization decisions we introduce the notion that it is not only the addition of distance considerations that matters but also the directionality of such changes doing so our study points to new theoretical and methodological insights to help address prior criticisms and advance future research

union status of young men in britain a decade of change previous empirical studies of individual union status in britain have been cross sectional in contrast we use longitudinal data from the national child development study to estimate the determinants of male trade union membership over the period 1981 1991 as suggested by union theories we find that it is important to control for unobserved individual heterogeneity and our preferred model allows for correlation of individual heterogeneity with observable variables our estimates reveal that the observed decline in very large workplaces and the contraction of the public sector explain about one third of the predicted decline in union membership over the period

the codetermined firm in oligopoly abstract a simple duopoly model is considered where firm owners bargain with employees representatives about employment but not about wages as is the case for codetermined firms in germany it turns out that for some range of the bargaining power a prisoner s dilemma exists bargaining is the dominant strategy although joint profits would be maximized with unrestricted profit maximization

an organizational model for understanding internationalization processes we propose an organizational model for understanding internationalization processes we argue that these processes differ with the type of organization we compare the internationalization processes of three organization types the mass production organization the disaggregated production organization and the project based organization each organization type responds differently to critical elements of the internationalization process namely the focus of entry the degree of presence and physical presence requirements in the foreign market which in turn influence what modal forms are adopted as the process progresses consequently we observe different approaches to resource commitment in the foreign market over time

intra and inter organizational imitative behavior institutional influences on japanese firms entry mode choice this paper compares the predictions of transaction cost and institutional theories in an empirical study of the entry mode choice for 1 194 japanese foreign subsidiaries the findings indicate the institutional model adds significant explanatory power over and above the predictions of the transaction cost model using the concepts of frequency based trait based and outcome based imitation i find support for institutional isomorphism as later entrants tended to follow the entry mode patterns established by earlier entrants isomorphic behavior was also present within a firm as firms exhibited consistency in entry mode choices across time further a firm s investment experience moderated institutional influences on entry mode choice

causes of the difficulties in internationalization we study the causes of the difficulties faced by firms when they internationalize in search of new markets we build on the resource based theory to argue that the difficulties in internationalization can be separated into three main sets based on their relationship to advantage loss of advantage provided by resources transferred abroad creation of a disadvantage by resources transferred abroad and lack of complementary resources required to operate abroad in each set we further distinguish difficulties that are specific to a firm from those that are common to a set of firms we argue that only a few of the resulting types of difficulties of internationalization are exclusive to the cross border expansion and propose solutions that address the root cause of each type

entrepreneurial growth the role of international knowledge acquisition as moderated by firm age in line with repeated recent calls for research on specific forms of growth rather than on an undifferentiated notion of total growth our study contributes to the understanding of entrepreneurial growth by this we mean growth through expansion into new geographic markets and or via the introduction of new products or services building on penrose s theory of the growth of the firm and on the research streams she has in part inspired we investigate the impact of knowledge acquisition from international markets on entrepreneurial growth both at home and abroad we further suggest that the effects of international knowledge acquisition on entrepreneurial growth will vary with firm age utilizing longitudinal data on 138 small and medium sized enterprises smes we find that the acquisition of knowledge from international markets fuels growth through market development and that this effect is stronger for international expansion than domestic expansion our results also show that firm age negatively moderates the relationship between international knowledge acquisition and entrepreneurial growth via the introduction of new products or services specifically international knowledge acquisition has a positive effect on growth via new products services development in young firms but a negative effect in mature firms we assume this reflects changes over time in how international knowledge is managed

risk aversion and trade union membership if trade unions provide only their members with insurance against income variations as a private good this insurance will provide a stronger incentive for more risk averse employees to become union members using data from the german socio economic panel soep and various direct measures of individual risk attitudes we find robust evidence of a positive relationship between risk aversion and the likelihood of union membership for full time employees this association is particularly strong for males and in west germany

the impact of mobile financial services usage on microfinance delinquency abstractthis paper studies the impact of mobile financial systems usage on microcredit delinquency ratios in tunisia by using either a two part model or matching econometric procedures our large dataset contains all of the administrative registers that belong to the six branches of enda the incumbent institution leader in tunisia we find a significant reduction of 4 92 days of late repayment for an average user of mfs in an environment where 15 of loans have been paid late at least once we foresee a tremendous opportunity to improve the mfis repayment ratios and consequently provide microcredit customers with more financing for income generating activities

institutional cultural and transaction cost influences on entry mode choice and performance in this study we examine foreign market entry mode choice and firm performance for a sample of european union firms examining both financial and non financial performance measures we attempt to determine if firms that select their entry mode based on transaction cost institutional context and cultural context variables perform better than firms that make other mode choices we found that mode choice did matter firms whose mode choice could be predicted by the extended transaction cost model performed significantly better on both financial and non financial measures than did firms whose mode choice could not be predicted by the extended transaction cost model implications for future research are discussed

internationalization as an evolutionary process the johanson and vahlne model of internationalization has been the main foundation of process research in international business since 1977 this model also known as the uppsala model provides a useful general framework for interpreting firm level processes increasing and occasionally decreasing resources committed to international operations however the model does not provide theoretical explanations of non linear and discontinuous dynamics of the process over time nor does it offer testable propositions we focus on the longitudinal dimension of internationalization specifically path breaking commitments that increase a firm s exposure to risk on this basis we examine the idea that the ip model represents an evolutionary process by emphasizing the role of novelty and introducing selection mechanisms we explain non linear and discontinuous dynamics of internationalization processes path breaking resource commitments create novelty and deviate from a gradual path of growth as firms take higher risks and hence face more intensive selection pressures in consequence firms are more likely to experience outstanding performance but are also more likely to experience failure this variation of outcomes is moderated by the resources a firm can draw upon in its ecosystem and by the volatility of its environment based on these ideas we develop testable propositions to advance the internationalization process model

international diversification and firm performance the s curve hypothesis a proposed theoretical framework for the study of multinationality and performance includes both benefits and costs of geographic expansion over different phases of internationalization data on 1 489 japanese firms over 12 years show a consistent horizontal x s shaped x relationship between multinationality and performance further firms investing more heavily in intangible assets such as technology and advertising achieved greater profitability gains from growth in foreign direct investment our framework and findings highlight complexity and temporal dynamics

modes of foreign entry a transaction cost analysis and propositions a frontier issue in international marketing is the appropriate choice of entry mode in foreign markets the objective of this paper is to offer a transaction cost framework for investigating the entry mode decision this framework provides 1 a theoretical basis for systematically interrelating the literature into propositions 2 propositions about interactions which resolve the apparently contradictory arguments advanced to date specifically the paper illustrates the feasibility of clustering 17 entry modes into the degree of control the mode provides the entrant proposes that the most appropriate i e most efficient entry mode is a function of the tradeoff between control and the cost of resource commitment advances testable propositions delimiting the circumstances under which each mode maximizes long term efficiency

limits to international entry mode learning in smes despite extensive research the literature is unclear about the circumstances under which a firm learns from its past foreign entry modes and how this experiential learning is related to future mode choices building on the internationalization process ip model and the idea that some experiential learning is location bound while other learning is non location bound we develop and test theory to explain how experiential learning about foreign operation modes and markets impact future mode choices in new foreign markets overall we argue that mode based experiential learning is limited through the repeated use of a specific operation mode firms develop routines and processes that are non location bound and can be replicated in new foreign markets leading to the use of this same mode type in new locations but when complemented by experiential learning about a target market region firms opt for operation modes with greater commitment in new foreign markets drawing on a sample of german smes and examining four different types of entry modes we find some support however we also identify a number of notable exceptions to our theory in this way we help provide unique new insights informing future ip model experiential learning and international entry mode research

organizational learning about new international markets exploring the internal transfer of local market knowledge this study examines the transfer of local market knowledge within the diversified firm as its divisions expand into a new host country within the u s based corporations in our sample both the nature of local market knowledge itself and differences in organizational structures significantly influence the extent of internal knowledge transfer among divisions the results suggest that as firms expand into new international markets their organizational learning processes differ significantly

peer group formation in an adverse selection model this paper develops an adverse selection model where peer group systems are shown to trigger lower interest rates and remove credit rationing in the case where borrowers are uninformed about their potential partners and ex post state verification or auditing by banks is costly peer group formation reduces interest rates due to a collateral effect namely cross subsidisation amongst borrowers acts as collateral behind a loan by uncovering such a collateral effect this paper shows that peer group systems can be viewed as an effective risk pooling mechanism and thus enhance efficiency notjust in the full information set up a well known family of adverse selection models in the stiglitz and weiss 1981 tradition demonstrates that when banks are imperfectly informed about the riskiness of borrowers projects and therefore cannot discriminate against risky borrowers interest rates become inefficiently high and worthy borrowers are driven out of the credit market the extent of this problem is substantially magnified when borrowers do not have adequate collateral to secure a loan typically adverse selection combined with lack of collateral leads to prohibitively high interest rates poorly endowed individuals e g students immigrants the unemployed and a vast majority of poor individuals in developing countries often face such high rates and therefore cannot take advantage of profitable investment opportunities a peer group formation system represents a possible solution to the above problem under this system a bank lends to borrowers without collateral on condition that the borrowers organise themselves into groups and that participant borrowers within each group accept to take joint responsibility for a loan thus in addition to repaying their own share of the loan each group member must accept to repay the obligations of their defaulting peers otherwise the entire group is denied access to future refinancing systems of this kind have been very successful in practice they have generated lower interest rates for the rural poor in for example bangladesh the philippines bolivia and the state of arkansas in the united states moreover group lending has also been successfully implemented in large urban areas such in the cities of dhaka and chicago 1

does privatization remove restrictive working practices evidence from uk establishments this study investigates the links between privatization and changes in working practices using data from the uk 1990 workplace employees relations survey privatization raises the probability of an establishment of experiencing reduced job demarcation and or increased flexibility in the use of the workforce by managers after exploration no clear association is found between ownership and the level of restrictive working practices

experiential knowledge and cost in the internationalization process using a behavioral approach this study identifies and delineates components of experiential knowledge in the internationalization process three hypotheses are developed and tested they center ar

impact of ownership on the international involvement of smes this paper analyses the relationship between the internationalisation strategies of smes and types of ownership different types of ownership affect firms and this in turn will influence the internationalisation strategy adopted using a sample of spanish smes our results show that internationalisation is negatively related to family ownership and positively related to corporate ownership we have also observed that the presence of a corporate blockholder in family firms encourages internationalisation these results support the idea that ownership type influences the decision to internationalise

closing knowledge gaps in foreign markets knowledge and learning are ascribed pivotal roles in firms internationalization processes perceived market uncertainties namely knowledge gaps related to business environments in foreign markets may curb firms inclinations to commit resources to these markets this study explores whether knowledge gaps tend to increase or decrease with time when operating in the foreign market and it discusses which learning components narrow or widen the perceived knowledge gap a theoretical model is developed based on the internationalization process view and the more recent organizational learning perspective including such concepts as overconfidence and absorptive capacity the theoretical model is tested on a set of primary data covering danish and swedish firms and their foreign market operations the results suggest a more subtle relationship between experience and perceived knowledge gaps than the mechanical relationship portrayed by the internationalization process view a relationship in which absorptive capacity and in particular overconfidence play important roles

loan officers gender and microfinance repayment rates this study examines the impact of loan officer characteristics on repayment rates of microfinance borrowers in mexico applying multilevel analyses with special attention to the impact of the gender of the loan officer on default rates the results strongly suggest that loan officers play a crucial role in improving repayment rates in microfinance and that male loan officers are better able to induce borrowers to repay than female loan officers this may be because men exert authority over women and face fewer problems working late travelling through unsafe places and combining a position as counsellor with enforcing repayment

co determination and innovation this paper examines the effect of the german co determination law of 1976 mitbestg on the innovative activity of german firms co determination applies to firms with 2 000 employees or more data from 1971 1976 and 1981 1990 on 148 firms are used to compare the number of patents granted to co determined firms before and after the introduction of the law several control variables are applied and in particular in order to avoid a possible bias from specific effects of firm size we compare the co determined firms with others before and after 1976 the results do not support the view that co determination slows down technological progress and reduces innovativity

how mncs choose entry modes and form alliances the china experience this study examine two dimensions of firms foreign market entry strategy mode of entry and formation of alliances based on the existing literature we propose a model that describes how host country home country and industry specific factors affect foreign firms decisions on how they enter the market and whether they will enter with a partner firm or not the model also describes how operation related factors i e the location and the level of local government affect these decisions seven major hypotheses were tested using a longitudinal sample of 2 998 foreign business activities in china between 1979 and 1993 our sample consists of foreign investing firms from the u s europe japan and other asian countries by choosing china as a host country the study offers insights into how firms of different regional groups adapted their strategies to a changing host environment

union membership and wage bargaining when membership is not compulsory this paper provides a formal model of union wage and membership determination where the union is recognized for bargaining purposes where membership of the union is not compulsory and where the union faces a budget constraint in its organization activities this simultaneous equation model is then used as the basis for estimation of manual wages and union density for the private sector using the 1990 workplace industrial relations survey copyright 1995 by royal economic society

internationalization and performance degree duration and scale of operations we assess the theoretical underpinnings and associated empirical findings of the three stage sigmoid curve relationship between degree of internationalization doi and performance by re examining the results reported in one of the prominent studies in the literature we further conduct our own analyses of 23 474 observations of 2 620 us manufacturing firms over the period 1976 2008 and account for self selection of firms into different degrees of internationalization by using a generalized propensity score estimator both sets of results show that the relationship between doi and performance conforms to a mostly negative sigmoid curve and does not support the three stage theorization further examination reveals that two major conceptual and empirical shortcomings underlie the disparity between the theoretical predictions of the three stage model and these empirical findings first whereas theory relies overwhelmingly on enhanced scale of operations as a causal mechanism through which internationalization contributes to performance empirical studies preclude proper identification of scale related benefits second theory and empirics tend to confuse temporary difficulties experienced upon entry into international markets with examining the benefits realizable at different levels of doi regardless of the firm s short term difficulties in realizing those benefits our empirical results show that correcting for each of these shortcomings contributes to diminishing the theory empirics gap

explaining the internationalization of ibusiness firms information and communication technologies have given rise to a new type of firm the ibusiness firm these firms offer a platform that allows users to interact with each other and generate value through user co creation of content because of this ibusiness firms face different challenges when they internationalize compared with traditional firms even those online in this article we extend existing internationalization theory to encompass this new type of organization we theorize that because ibusiness firms produce value through the creation and coordination of a network of users these firms tend to suffer greater liabilities of outsidership when expanding abroad and therefore concentrate on network and diffusion based user adoption processes as they internationalize based on a multi case investigation of a sample of ibusiness firms we develop new theory and testable hypotheses thus we make an important contribution by expanding internationalization theory to a new set of firms

the union membership wage premium puzzle is there a free rider problem economists have long suggested that labor unions suffer a free rider problem the argument is that since union set wages are available to all workers covered by unions irrespective of their union status and union membership entails costs workers will only join if they are coerced or are offered non wage goods that they value above membership costs yet u s and british empirical research has found a substantial union membership wage premium among private sector union covered workers implying that there is no free rider problem the authors of this study hypothesize that these findings arise due to selectivity problems associated with identifying the union membership effect their analysis which uses rich data from a new linked employer employee survey for britain and exploits the within establishment variation in wages as a function of individual union membership status demonstrates that the apparent wage premium for members is illusory hence a potential free rider problem remains author s abstract free full text download available at http digitalcommons ilr cornell edu ilrreview

microfinance in times of crisis the effects of competition rising indebtedness and economic crisis on repayment behavior this paper analyzes repayment determinants for loans from caja los andes a bolivian mi crolender the analysis focuses on the influence of recent changes in the bolivian microfinance market in particular we examine the effects of the rapidly growing supply of funds for micro loans the increasing competition a rising level of indebtedness among micro entrepreneurs and the recent economic crisis our results show a two fold influence structure of competition and indebtedness firstly clients with loans from multiple sources at the same time are found to be more likely to default than others secondly clients with given characteristics have an overall better repayment behaviour in areas with higher competition and a higher supply of micro loans

mimetic and experiential effects in international marketing alliance formations of us pharmaceuticals firms an event history analysis alliances are recognized as an indispensable tool for managers operating in a global business environment and as a fundamental stage of the internationalization process of the firm drawing on a co evolutionary framework this article investigates the mimetic and experiential effects in international alliance formation we focus on a critical unresolved issue in the literature what is the role of mimetic behavior and previous alliance experience in mitigating the uncertainty associated with engaging in cross border operations an event history analysis of 792 international marketing alliance formations initiated by 317 firms in the us pharmaceutical industry is employed to test the hypotheses the findings of two different hazard rate models reveal significant complex effects of density and cross border alliance experience on the propensity to engage in new international marketing alliances

customer involvement and service firm internationalization performance an integrative framework to overcome the costs of doing business abroad researchers have suggested either legitimacy or efficiency based solutions however both types of solutions still treat host country customers as external to the theory we highlight the role of customers in the international professional business service setting and argue that customer involvement is positively related to the perceived internationalization performance of multinational corporations mncs mncs with managers who perceive higher legitimacy pressures and greater needs for local knowledge tend to undertake greater efforts to build customer involvement furthermore we develop a configuration framework between perceived strategic needs and mncs capabilities specifically mncs that match relational capability with legitimacy needs and absorptive capacity with knowledge needs are more likely to engage in customer involvement our survey of 175 chinese mncs provides evidence that customer involvement is positively related to perceived internationalization performance when mncs relational capabilities are stronger the positive relationship between legitimacy pressure and customer involvement increases by contrast mncs with greater perceived market ambiguity improve customer involvement only when they have stronger absorptive capacity we conclude that mncs may simultaneously reduce legitimacy and efficiency costs through customer involvement after considering the fit between perceived environmental pressures and firm capabilities

evaluating export promotion programmes uk overseas trade missions and export performance this paper examines the extent to which firms knowledge and structural characteristics as well as firms behaviour in foreign markets following trade mission participation impacts upon trade mission success and export performance the findings suggest that 1 a diversification strategy in terms of export markets benefits future expansion into new foreign markets 2 specific knowledge about the targeted markets should be acquired prior to participating in the trade missions 3 communication with potential business partners should be established prior to participating in the trade missions and 4 the business relationships established before and during the trade missions should be cultivated through regular contacts using not only communication technology but also regular visits in summary overseas trade missions contribute to the generation of incremental sales in foreign markets by enhancing the relationship building process between business partners

a note on the transnational solution and the transaction cost theory of multinational strategic management this article assesses the extent to which the results of bartlett and ghoshal s 1989 work can be incorporated in what has now become one of the core explanations of multinational strategic management i e the transaction cost based theory of international production we demonstrate that the transaction cost approach fully incorporates the empirical findings of bartlett and ghoshal s work to do so requires that we make a new distinction between location bound and non location bound firm specific advantages in addition three possible uses of country specific advantages by multinational enterprises need to be identified while the transnational solution as proposed by bartlett and ghoshal is not itself a new theory of multinational strategic management it is compatible with the transaction cost based model of multinational strategic management

peer monitoring and credit markets a major problem for institutional lenders is ensuring that borrowers exercise prudence in the use of the funds so that the likelihood of repayment is enhanced one partial solution is peer monitoring having neighbors who are in a good position to monitor the borrower be required to pay a penalty if the borrower goes bankrupt peer monitoring is largely responsible for the successful financial performance of the grameen bank of bangladesh and of similar group lending programs elsewhere but peer monitoring has a cost it transfers risk from the bank which is in a better position to bear risk to the cosigner in a simple model of peer monitoring in a competitive credit market this article demonstrates that the transfer of risk leads to an improvement in borrowers welfare

on the internationalization process of firms a critical analysis even though international marketing has been challenged because of theoretical and methodological shortcomings very few researchers have actually attempted to analyze the weaknesses based on principles of theory evaluation in this article the author examines two types of models addressing the individual firm s internationalization process a theory evaluation is performed based on the explanation and the falsification criteria in order to improve the internationalization models some measures are proposed

an institutional approach to cross national distance cross national distance is a key concept in the field of management previous research has conceptualized and measured cross national differences mostly in terms of dyadic cultural distance and has used the euclidean approach to measuring it in contrast our goal is to disaggregate the construct of distance by proposing a set of multidimensional measures including economic financial political administrative cultural demographic knowledge and global connectedness as well as geographic distance we ground our analysis and choice of empirical dimensions on institutional theories of national business governance and innovation systems in order to overcome the methodological limitations of the euclidean approach we calculate dyadic distances using the mahalanobis method which is scale invariant and takes into consideration the variance covariance matrix we empirically analyze four different foreign expansion choices of us companies to illustrate the importance of disaggregating the distance construct and the usefulness of our distance calculations which we make freely available to managers and scholars

experiential knowledge and costs in the internationalization process using a behavioral approach this study identifies and delineates components of experiential knowledge in the internationalization process three hypotheses are developed and tested they center around the lack of knowledge in the areas of foreign business foreign institutions and firm internationalization as well as the effect that this lack of knowledge has on managers perceived cost in the internationalization process with the help of a lisrel based structural model the three hypotheses are tested on a sample of 362 service firms the analysis shows that lack of internationalization knowledge has a strong impact on the lack of both business and institutionalization but there is no direct effect of lack of internationalization knowledge on perceived cost of internationalization

codetermination as a strategic advantage abstract a theoretical model of codetermination is considered where consistent with german institutions firm owners bargain with employees representatives about employment but not about wages a duopoly and a more general oligopolistic situation are analyzed for some range of bargaining power a prisoner s dilemma exists codetermination leads to increased profits if the other firm is a traditional profit maximizer bargaining is the dominant strategy although joint profits would be maximized with unrestricted profit maximization the theory is tested with data from 22 german firms who operate in the same markets over 23 years codetermined firms actually show a different behavior than other companies

yes we really do need more entry mode studies a commentary on shaver in a recent commentary published in this journal shaver raises the provocative question of whether we need more entry mode studies after assessing the reasons for shaver s doubts and further developing his broad research suggestions we conclude that this question should be answered affirmatively we derive three important questions for future entry mode research 1 what determines the evolution of operations resulting from suboptimal mode choices 2 what causes the replication of past mode choices 3 how is the entry decision process structured focusing on these questions should assure a bright future for entry mode research

experience imitation and the sequence of foreign entry wholly owned and joint venture manufacturing by south korean firms and business groups in china 1987 1995 the evolution of foreign entry in the form of joint ventures and wholly owned manufacturing operations is examined as a staged process shaped by experience and imitation dynamics at the firm group and industry levels of analysis the expansion of south korean firms into china between 1987 and 1995 lends support to the staged view of foreign entry over time technology intensive firms are more likely to abandon joint venture entry modes owing to contractual hazards firms in the same business group are found to imitate each other s choice of joint ventures and wholly owned plants firms in the same industry mimic each other s choice of wholly owned plants though not of joint ventures

foreign direct investment and local linkages this paper analyses the pattern of local linkages in foreign direct investment fdi treating such local linkages as an investment in local relationships using taiwanese manufacturing firms investing abroad as the sample for our case study we find that the local linkage intensity of a foreign subsidiary differs by fdi location entry mode firm size and the nature of the production network in which an investor is embedded more local linkages will be pursued by an investor if it is in search of distinctive and inimitable resources as opposed to homogeneous and reproducible resources investment in local linkages always begins with the linkage that carries the lowest risk to the original business network for manufacturing firms the sequence of such linkages is workers components and parts subcontracting and finally sources of r d

the uppsala internationalization process model revisited from liability of foreignness to liability of outsidership the uppsala internationalization process model is revisited in the light of changes in business practices and theoretical advances that have been made since 1977 now the business environment is viewed as a web of relationships a network rather than as a neoclassical market with many independent suppliers and customers outsidership in relation to the relevant network more than psychic distance is the root of uncertainty the change mechanisms in the revised model are essentially the same as those in the original version although we add trust building and knowledge creation the latter to recognize the fact that new knowledge is developed in relationships

can multinational enterprises light up developing countries evidences from the access to electricity in sub saharan africa summary this paper examines the role that multinational enterprises mnes and foreign direct investments fdi can have in enhancing the access to electricity for local communities in developing countries based on the quality of home and host institutions access to electricity is a marker for development but it is far from being universal in developing countries the shortage of electricity is mainly the consequence of inability of governments in planning financing and developing necessary electricity infrastructure in this context investments from other actors can be essential particularly we focus on the role of fdi and mnes we claim that when mnes invest in developing countries they are incentivized to solve the lack of electricity infrastructure mainly for two reasons to guarantee their business activities and to gain legitimacy with their local stakeholders in addition we argue that mnes and fdi from institutionally underdeveloped countries will be more prone to develop infrastructure for the provision of electricity to local population as generally they suffer from a negative stereotype for this study we rely on 1 547 observations composed of pairs of 83 home countries and 15 host countries in sub saharan africa observed from 2005 to 2011 due to the nature of the database we adopt panel data techniques i e system gmm and corrected least square dummy variable estimators we find that fdi promotes access to electricity in developing countries with weak institutions and this is more likely true when fdi come from institutionally underdeveloped countries these results are far from obvious as they controvert common idea among institutional scholars that a regulatory authority is essential in the provision of infrastructure in conclusion with this paper we partially rehabilitate the image of mnes investing in developing countries by demonstrating that under certain conditions they could contribute to energy poverty alleviation of local population

the effect of social capital on group loan repayment evidence from field experiments an important question to microfinance is the relevance of existing social capital in target communities to the performance of group lending this research presents evidence from field experiments in south africa and armenia in which subjects participate in trust and microfinance games we present evidence that personal trust between group members and social homogeneity are more important to group loan repayment than general societal trust or acquaintanceship between members we also find some evidence of reciprocity those who have been helped by other group members in the past are more likely to contribute in the future during the past decade exploring the role that social capital plays in economic behaviour has emerged as one of the most fascinating and fertile areas of economic research although precise definitions of social capital are notoriously difficult to pin down one of the early pioneers of the concept coleman 1988 defines social capital as social structure that facilitates certain actions of actors within the structure in his definition coleman specifically highlights the roles of mutual obligation expectations and trustworthiness social norms social sanctions and the transmission of information important studies in both developed and developing countries have analysed the impact of social capital in economic relationships putnam s celebrated work making democracy work civic traditions in modern italy 1993 and bowling alone america s declining social capital 1995 brought attention to the role that social capital plays in the development of the modern state udry s ground breaking 1994 work in nigeria illustrated how the social capital existing in traditional societies may allow for more efficient credit contracts than in developed economies with weaker social

unions and workers welfare in chinese firms based on a survey of 1 268 firms in 12 cities this article empirically studies unions effects on worker welfare in china regressions carried out on a rich set of specifications show that unionization is significantly associated with higher hourly wages and larger pension coverage and weakly associated with lower monthly working hours further econometric analysis finds that unions promote individual and collective contracts the effect of collective contracts vanishes when unions are present whereas individual contracts have independent and positive effects in addition unions have effects on workers welfare independent of collective and individual contracts

learning from age difference interorganizational learning and survival in japanese foreign subsidiaries this paper extends research on experiential learning of foreign subsidiaries by exploring the temporal conditions under which a foreign subsidiary can benefit from the experience of its sister subsidiaries building upon organizational evolution and learning literature we propose that differences in entry timing among sister subsidiaries provide structural conditions that bound the opportunities for inter subsidiary learning we argue that different entry cohorts of sister subsidiaries are beneficial to a focal subsidiary as they provide non redundant complementary experience from their different operational stages and ignite the motivation to learn our empirical analysis of japanese foreign subsidiaries provides strong evidence that survival is enhanced by the experience of different entry cohorts of sister subsidiaries but not by that of similar cohorts qualitative evidence also shows that multiple channels of experience exchange across sister subsidiaries lead to actual learning we further show that the survival benefit derived from different cohorts is contingent on the level of environmental change as well as on the level of experience of the focal subsidiary and its parent firm our research highlights the importance of temporal heterogeneity in the internationalization process and offers implications for the temporal strategy of multinational companies

internationalising in small incremental or larger steps we argue that companies may enter foreign environments either incrementally as suggested by long established theory or by taking larger steps that may result in lower initial performance but through learning and experience lead to increased performance in future expansions this idea is corroborated by the experience of dutch companies entering into central and eastern europe we also find that expansion steps may be too large thereby limiting the exploration of foreign environments our study suggests that sequential internationalisation strategies do still matter and that companies have to balance exploitation and exploration in internationalisation

the ownership structure contingency in the sequential international entry mode decision process family owners and institutional investors in family dominant versus family influenced firms extending our understanding of family firms and international business research with respect to entry mode decisions this study explains how entry mode choice is the product of a sequential decision making process with an important ownership structure contingency we propose that firms with a dominant family owner family dominant firms prefer low equity ownership as their entry mode for the purpose of preserving their socioemotional wealth their preference is persistent even when the institutional investors are the dominant shareholders in the firm family influenced firms this nuanced examination of the role family values play in the entry mode decision extends our understanding of how family firms enter international markets

the effect of national culture on the choice of entry mode characteristics of national cultures have frequently been claimed to influence the selection of entry modes this article investigates this claim by developing a theoretical argument for why culture should influence the choice of entry two hypotheses are derived which relate culture to entry mode choice one focusing on the cultural distance between countries the other on attitudes towards uncertainty avoidance using a multinomial logit model and controlling for other effects the hypotheses are tested by analysing data on 228 entries into the united states market by acquisition wholly owned greenfield and joint venture empirical support for the effect of national culture on entry choice is found

outreach sustainability and leverage in monitored and peer monitored lending abstract i study the contract design problem facing microfinance lending organizations mfos that want to maximize the impact and outreach of their lending activities to a target population of poor borrowers while remaining financially sustainable tradeoffs between outreach sustainability and financial leverage are shaped by the endogenous monitoring and delegation costs that arise within a chain of agency relationships subject to moral hazard between borrowers loan staff mfo equity owners and outside investors all else equal sustainable mfos that target poorer borrowers must charge higher interest rates have higher staff costs per dollar loaned and are less leveraged analysis of data for 72 mfos tends to support the findings

from internationalization to evolution the uppsala model at 40 years abstract the original uppsala model that was published in 1977 explains the internationalization process of firms we have further developed the model several times in the intervening years the present article is our latest effort a general model of the evolution of the multinational business enterprise mbe from early steps abroad to being a global firm the updated augmented model explains mbe evolution in general not only characteristics of the internationalization process in a narrow sense we believe that the newest iteration anchored in process ontology will be useful in conducting longitudinal empirical studies

speed of the internationalization process the role of diversity and depth in experiential learning by analyzing internationalization as a dynamic process we attempt to explain the speed of international operations in terms of learning acquired in the course of past international activities we consider that the speed of the internationalization process depends on the type of experiential learning that results from decisions implicit in the internationalization process choice of location and modes of operation firms develop two types of learning activities with respect to the selection of foreign markets and modes of operation diversity and depth of accumulated international activities we propose that depth of international activities has an inverted u shaped impact on the speed of the internationalization process while diversity of international activities has a u shaped influence on the speed of internationalization process the results of our longitudinal study of 889 firms over 23 years 1986 2008 suggest that diversity of international activities promotes long term learning by exposing the firm to richer experiences although such learning only takes place over time depth of international activities may accelerate the internationalization process in the short term but it eventually restrains its potential for development in the long term our research highlights the short term vs long term consequences of different types of decisions related to the internationalization process

wait and see strategy risk management in the internationalization process model we interpret the wait and see strategy as a decision to maintain unchanged the firm s commitments to its business network relationships to explain why firms choose a wait and see strategy we propose an extension to the relationship commitment decisions aspect of the uppsala internationalization process ip model with this development we explain that the wait and see strategy can result from a change in the levels of risk assumed in the firm and not only from the decision to adjust the risk that the firm encounters by changing commitments to its network relationships this development enhances the ability of the ip model to accommodate contextual influences on relationship commitment decisions and to explain a more complete suite of internationalization trajectories extending the theoretical core of the ip model further confirms its efficacy its application to international strategy and its potential to be developed as a general process model of strategic change

trade unions v statistical discrimination theory and application to post apartheid south africa a simple model of statistical discrimination is analyzed which captures some stylized facts of the south african labor market it shows that this type of discrimination disappears when the wage rates are determined by efficient bargaining between a representative firm and a union with endogenous membership this may explain why the wage gap between black and white workers in post apartheid south africa is smaller among unionized workers than among non unionized ones

sme internationalization modes in the german biotechnology industry the influence of imitation network position and international experience in this article we reveal how network enabled imitation processes impact young small and medium sized enterprises smes internationalization and how a firm s network position as well as its experiential knowledge moderate imitative behavior in internationalization modes building on institutional network and organizational learning theory we suggest that firms imitate the internationalization modes of their peers in their network moreover we argue that a firm s imitation propensity depends on two important boundary conditions network position and past experience applying a longitudinal event history analysis to analyze the complete population of 977 german biotechnology firms between 1996 and 2012 largely supports our hypotheses our findings reveal that firms imitate the internationalization modes of their peers in a precise manner this implies that the imitation of others can initially serve as a presumably convenient low risk shortcut to a planned or experience driven internationalization process furthermore our results confirm that this imitation process is channeled through formal network relations and that central network positions that are associated with superior information access enhanced legitimacy and status may promote deviating behavior acknowledging the interplay of different learning sources our findings additionally show that initial internationalization mode choices of smes can have a lasting effect on subsequent internationalization behavior overall our study contributes to a more nuanced view of imitative behavior of internationalizing smes and its boundary conditions and highlights future research opportunities that exist for considering imitation and its implications in international business research

what s in a p reassessing best practices for conducting and reporting hypothesis testing research social science research has recently been subject to considerable criticism regarding the validity and power of empirical tests published in leading journals and business scholarship is no exception transparency and replicability of empirical findings are essential to build a cumulative body of scholarly knowledge yet current practices are under increased scrutiny to achieve these objectives jibs is therefore discussing and revising its editorial practices to enhance the validity of empirical research in this editorial we reflect on best practices with respect to conducting reporting and discussing the results of quantitative hypothesis testing research and we develop guidelines for authors to enhance the rigor of their empirical work this will not only help readers to assess empirical evidence comprehensively but also enable subsequent research to build a cumulative body of empirical knowledge

screening by the company you keep joint liability lending and the peer selection effect we look at an economic environment where borrowers have some information about the nature of each other s projects that lenders do not we show that joint liability lending contracts similar to those used by credit cooperatives and group lending schemes will induce endogenous peer selection in the formation of groups in a way that the instrument of joint liability can be used as a screening device to exploit this local information this can improve welfare and repayment rates if standard screening instruments such as collateral are unavailable

group lending sequential financing lender monitoring and joint liability abstract we develop a simple model of group lending based on peer monitoring and moral hazard we find that in the absence of sequential financing or lender monitoring group lending schemes may involve under monitoring with the borrowers investing in undesirable projects moreover under certain parameter configurations group lending schemes involving either sequential financing or a combination of lender monitoring and joint liability are feasible in fact group lending schemes with sequential financing may succeed even in the absence of joint liability though the repayment rate will be lower in the absence of joint liability however group lending with lender monitoring is unlikely to be feasible

from the editors experimental designs in international business research the question that motivated this editorial was where are the ib experiments the short answer is that experiments are largely absent from the ib literature and we argue that they shouldn t be experimental methods offer the opportunity to significantly improve the evidence for the causal relationships in international business research in a variety of ways in this article we highlight the value and limitations of experiments in ib research and explain the basic tenets of experimental design and thinking with the goal of encouraging the submission of more papers with an experimental design to jibs

open shop unions and product market competition in this paper we analyse the impact of changes in product market competition on wage outcomes in the presence of an open shop union with less than full union membership product market competition is shown to aect not only a unionised rm s pro ts but also its payoin the event of a dispute in contrast to the pre diction of the standard model increases in product market competition may now increase wage levels the model is therefore able to accommodate the mixed empir ical ndings regarding the impact of product market competition on union wages
