regional diversification and firm performance this study examines how regional diversification affects firm performance the results indicate that regional diversification has linear and curvilinear effects on firm performance regional diversification enhances firm performance linearly up to a certain threshold and then its impact becomes negative the results also show that firms of developed countries maximize their performance when they operate across a moderate number of developed regions and a strictly limited number of developing regions this explains why internationalization by most international firms is regional rather than global

capital flow controls international asset pricing and investors welfare a multi country framework this paper investigates the impact of capital flow restrictions on the pricing of securities on the optimal portfolio composition for investors of different nationalities and on their welfare under capital flow controls the equilibrium price of a security is determined jointly by its international and national risk premiums and investors acquire nationality specific portfolios along with a market wide proxy for the world market portfolio removal of investment barriers generally leads to an increase in the aggregate market value of the affected securities and all investors favor a move toward market integration introduction of different types of index funds in the world market generally increases world market integration and investor welfare in recent years the international capital markets have undergone numerous important changes that have increased the international linkage of national markets these changes include the creation of national index funds e g mexico korea taiwan india france and scandinavia and selective liberalization e g brazil india korea sweden and japan despite their potential impact on the national economies and global finance it is not clear what consequences these integrating changes entail for example is welfare increased by allowing cross border investment that is restricted to purchasing the entire national portfolio of which the national index fund is a class unfortunately with the exception of subrahmanyam 1975a who studies the pricing and welfare effects of fully integrating heretofore completely segmented markets other international asset pricing models that incorporate capital flow restrictions for instance black 1974 stulz 1981b lessard et al 1983 errunza and losq 1985 cooper and kaplanis 1986 and eun and janakiramanan 1986 analyze the pricing but not the welfare effects of investment barriers to analyze systematically the welfare implications of various structural changes in the current market environment this paper follows the lead of subrahmanyam and recasts the analysis in two important respects

a market performance comparison of u s firms active in domestic developed and developing countries direct foreign investment dfi may benefit investors through superior cash flows or lower risk relative to purely domestic firms this paper considers three groups of u s firms those without significant international operations those with international operations in developed countries and those with international operations in developing countries after performing risk return performance analysis on the three groups the findings show developing country dfi results in inferior performance but that there are no statistically significant differences in market performance among the three

optimal liberalization of financial markets abstract as financial markets become completely liberalized countries gain from improved risk sharing but less wealthy countries can no longer profit from borrowing abroad at the lower rate and reinvesting at home at the higher rate with decreasing rather than constant returns to capital the gain from risk sharing is more likely to dominate the loss of the difference between the borrowing rate abroad and the decreasing reinvestment rate at home complete liberalization is likely to be optimal for less wealthy countries unless their labor endowment is large their productivity is large or holdings by foreigners are small as in china

firm size and the nature of innovation within industries the case of process and product r d the effect of firm size on the allocation of r d effort between process and product innovation is examined it is hypothesized that relative to product innovations process innovations are less saleable in disembodied form and spawn less growth this implies that the returns to process r d will depend more on the firm s output at the time it conducts its r d than the returns to product r d incorporating this distinction in a simple model the authors derive and test predictions about how the fraction of r d devoted to process innovation varies with firm size within industries

measuring organizational downside risk despite widespread incorporation of risk measures in strategy research there is little consensus regarding the meaning and measurement of risk in contrast to the variability measures widely used in strategy studies this paper draws from behavioral decision theory finance and management theory to present an alternative perspective on organizational risk downside risk the paper explains three categories of organizational downside risk measures based on the concept of lower partial moments the latter sections of the paper present considerations involved in specifying operational measures of downside risk and an empirical comparison of alternative downside risk measures

top managerial prestige and organizational bankruptcy this paper extends earlier work on an alternative view of bankruptcy suggesting that bankruptcy occurs when creditors withdraw then support from a firm s top management team it further proposes that support for the top team depends upon the team s prestige five characteristics measuring the relative status of top teams were tested for their association with bankruptcy three of the characteristics focused on items commonly associated with membership in economic elites elite educational backgrounds board memberships and previous employment as officers in other corporations the fourth and fifth characteristics focused on membership in political and military elites the results indicated that political and board connections were negatively associated with bankruptcy in the year of failure even when financial factors and cooptive board linkages were controlled the results also showed that failing firms attempted to improve their managerial prestige three to four years before they failed they were how

an intertemporal model of international capital market segmentation this paper develops an intertemporal model of international capital market segmentation within the model under various forms of segmentation integration the equilibrium asset prices and allocations the risk free interest rate and the intertemporal consumption behavior and welfares of two countries are derived and compared it is shown that the equilibrium interest rate is increased on integration and that integrating markets may be significantly welfare decreasing for one of the countries conditions that may lead to a decrease in welfare are investigated the conclusions as to the effects of segmentation on asset prices in the mean variance model of the existing finance segmentation literature are also shown to break down in an intertemporal model

performance effects of added cultural distance in the path of international expansion the case of german multinational enterprises this paper contributes to the debate on the performance impact of added cultural distance in the multinational enterprise s mne s expansion path our research focuses on the ability of mnes to handle complexity associated with added cultural distance in international expansion and on the effect this may have on profitability we hypothesise that firms that make expansion moves involving a high level of added cultural distance per unit of time and those that expand in culturally distant countries in an irregular fashion that is with a higher variability will be less profitable we test these hypothesised relationships using detailed data on 2404 expansion moves undertaken by our panel of 91 german mnes whose expansion paths we tracked during periods ranging between 5 and 20 years

modelling cost structure the bell system revisited this paper analyses a recent public policy decision and the crucial role played by the choice of the functional form the break up of the bell system is indeed a classic case of anti trust settlement and constitutes one of the most prominent and controversial applications of microeconomics to public policy it is argued that demanding multi output cost properties such as economies of scope for this is the considerable robustness problem displayed by the tranlog cost functional form the reason for this is the considerable able to robustness problem displayed by the translog cost function which is the source underlying many of the expert disagreements it is suggested that the non robustness is due to what ils termed the flip flop property and it is shown that the available empirical evidence from the pre divestiture bell system supports this argument to obtain robust results we propose that the analysis is constrained to the proper region of the cost function we propose that the analysis is con

the role of american depositary receipts in the development of emerging markets using a sample of 28 stock markets this chapter presents an empirical exploration of the effect of american depositary receipts adrs on emerging market development we examine the role of adrs on three aspects of market development openness defined as the degree of market transparency and reliability liquidity a measure of market activity and growth which attempts to measure the market s ability to foster the formation of new enterprises and encourage economic growth the preliminary evidence from the study is mixed adrs are instrumental in increasing openness but negatively impact both liquidity and the ability of the local market to foster economic growth also the effect of large firms listing adrs is detrimental to the development of the local market

multinational corporations vs domestic corporations financial performance and characteristics the analysis in this paper is composed of two segments first the financial performance of a sample of multinational corporations mncs is compared with that derived for a control group of domestic corporations dmcs using market based performance measures then the paper presents a comparison of selected financial characteristics of the firms in the two groups the results suggest the dmcs appear to have a significantly superior risk adjusted market based performance are significantly less capitalized and have higher total risk as well as higher systematic risk the fact that mncs are substantially larger than dmcs is not found to be a significant factor in explaining the observed difference between the two groups performance

on the effects of barriers to international investment a simple model is presented in which it is costly for domestic investors to hold foreign assets the implications of the model for the composition of optimal portfolios at home and abroad are derived it is shown that all foreign assets with a beta larger than some beta plot on either one of two security market lines some foreign assets with a beta smaller than are not held by domestic investors even if their expected return is increased slightly while it is obviously not true that asset markets are completely segmented between countries there is evidence of barriers to international investment although reality seems to lie in that grey area between complete segmentation and no segmentation at all most international asset pricing models are concerned with the extreme case of no barriers to international investment no effort seems to have been made to study the effect on portfolio choice of such barriers which make it costly to hold foreign securities as opposed to domestic securities but which do not in general render international diversification so onerous that investors avoid foreign securities completely casual empiricism suggests that models without barriers to international investment should be suspect those models cannot explain why it appears that in every country investors on average hold more domestic securities than would be required if they held the world market portfolio 2 this paper constructs a model of international asset pricing in which there is a cost associated with holding either long or short risky foreign securities for the sake of simplicity in most of the paper we assume that while domestic investors face barriers to international investment foreign investors face no such barriers it turns out that nothing significant is lost with such an assumption the main conclusions of this paper for the case in which foreign investors face no barriers to international investment are 1 in the presence of barriers to international investment some risky foreign

strategic implications of darwinian economics for selling efficiency and choice of integrated or independent sales forces most managers when confronted with a difficult strategic decision would like to know what is the prevailing practice in their industry prevailing practice interests managers in part because it may indicate which decisions are good even best the rationale is darwinian economics which proposes that competitive markets operate to force at least an approximation of optimal behavior because wrong decisions are extinguished by the market mechanism if so the bulk of survivors make good business decisions and their collective practice is worth knowing meaning it should be difficult to improve upon this paper tests whether prevailing practice represents good decisions the context is the decision whether to fill a sales district with a company integrated sales force or with outside agents independents the outcome of the choice is the ratio of sales to the cost of running the sales force i e selling efficiency a model is described which summarizes industry decisions and two propositions are developed proposition 1 a simple version states that efficiency declines as firms depart from the industry rule as to when they should integrate proposition 2 a contingent version states that efficiency declines as firms depart from the industry rule in unpredictable selling environments but that conforming to the rule has no impact in predictable environments the rationale is that firms learn the environment well enough to know when to depart from the rule in predictable settings but not otherwise the relationship between efficiency and conformity to prevailing practice is examined for 93 sales districts of 11 recognized electronic component manufacturers the results support proposition 2 the most efficient sales forces conform to prevailing practice and the least efficient deviate but only in uncertain environments in more certain environments conformity and efficiency are unrelated implications such as when it pays to be different and suggestions for future research are discussed

an intertemporal general equilibrium model of asset prices this paper develops a continuous time general equilibrium model of a simple but complete economy and uses it to examine the behavior of asset prices in this model asset prices and their stochastic properties are determined endogenously one principal result is a partial differential equation which asset prices must satisfy the solution of this equation gives the equilibrium price of any asset in terms of the underlying real variables in the economy in this paper we develop a general equilibrium asset pricing model for use in applied research an important feature of the model is its integration of real and financial markets among other things the model endogenously determines the stochastic process followed by the equilibrium price of any financial asset and shows how this process depends on the underlying real variables the model is fully consistent with rational expectations and maximizing behavior on the part of all agents our framework is general enough to include many of the fundamental forces affecting asset markets yet it is tractable enough to be specialized easily to produce specific testable results furthermore the model can be extended in a number of straightforward ways consequently it is well suited to a wide variety of applications for example in a companion paper cox ingersoll and ross 7 we use the model to develop a theory of the term structure of interest rates many studies have been concerned with various aspects of asset pricing under uncertainty the most relevant to our work are the important papers on intertemporal asset pricing by merton 19 and lucas 16 working in a continuous time framework merton derives a relationship among the equilibrium expected rates of return on assets he shows that when investment opportunities are changing randomly over time this relationship will include effects which have no analogue in a static one period model lucas considers an economy with homogeneous individuals and a single consumption good which is produced by a number of processes the random output of these processes is exogenously determined and perishable assets are defined as claims to all or a part of the output of a process and the equilibrium determines the asset prices our theory draws on some elements of both of these papers like merton we formulate our model in continuous time and make full use of the analytical tractability that this affords the economic structure of our model is somewhat similar to that of lucas however we include both endogenous production and

a three stage theory of international expansion the link between multinationality and performance in the service sector it is generally assumed that the performance of a firm improves with greater multinationality yet recent empirical studies have shown both a u shaped relationship which suggests an initially negative effect of international expansion on performance before the positive returns of international expansion are realized and an inverted u shaped relationship which suggests that international expansion beyond an optimal level is again detrimental to performance and results in a negative slope this paper proposes a new unified three stage theory of international expansion that incorporates both concepts in a sigmoid hypothesis it then tests this on data from 11 service industries highlighting the difference between knowledge based and capital intensive service sectors

from m p to ma p multinationality alignment and performance rather than searching for a universal optimal level of multinationality for all firms we argue that firm specific attributes should result in firm specific optimal levels of multinationality specifically we draw upon transaction cost and internalization theory to argue that there will be different optimal levels of multinationality for individual firms and if firms internalize foreign operations to an extent less than or greater than their individual optimal levels transaction costs will increase and performance will decrease to test this idea we use transaction cost models in the context of large us law firms during the time period from 1986 through 2008 to estimate firm specific optimal multinationality next we test relationships between alignment with or deviations from firm specific optimal levels of multinationality and performance ma p consistent with the ma p hypothesis insufficient and excessive levels of multinationality are both negatively related to financial performance in addition excessive multinationality is positively associated with downside performance risk one key implication is that an ma p approach may offer greater theoretical validity and clarity than traditional multinationality and performance m p approaches

are multinational corporations safer the failure probabilities of a sample of multinational corporations mncs are derived and compared with those of a control group of domestic corporations dmcs the results suggest that the mean insolvency probability of dmcs is significantly higher than that of the mncs it is also observed that mncs are significantly more capitalized and the standard deviation of their equity as well as their average systematic risk are also significantly lower furthermore the average insolvency probability of the dmcs is more sensitive to changes in the values of the parameters than those of the mncs

unnatural monopolies in local telephone we attempt to overcome the serious data problems of past telecommunications cost studies by focusing on local exchange carriers lecs with enough degrees offreedom to yield precise estimates our global subadditivity tests show that the cost function is definitely not subadditive the results suggest that the benefits to breaking up the monopoly outputs of existing lecs substantially outweigh the potential losses in efficiency they also support permitting entry and increasing competition in local exchange markets furthermore given the competitive nature of long distance service it is doubtful that the predivestiture bell system was a natural monopoly

multinationality and performance among british manufacturing companies over the period 1972 84 profitability among 304 large british manufacturing companies was positively related to their degree of multinationality moreover increases in overseas production were strongly associated with increases in sales and profitability the profitability of multinational growth over the whole period was independent of its destination supporting the view that the primary source of the superior performance of multinationals was competitive advantage rather than the higher rate of profit in the industries of other countries

on the determinants of net foreign investment these models do not explain why investments in productive processes in any country exceed or fall short of the wealth of the residents of that country most existing models of portfolio choice and asset pricing make the key assumption of a given world market portfolio which implies that at any point in time net foreign investment itself is given 2 the present paper does not make this assumption this paper provides a simple model of net foreign investment in a world of perfect markets 3 the model has the useful property that production decisions are made simultaneously with portfolio choice decisions as in cox ingersoll and ross 1978 the central feature of the model is that technologies in use differ across countries it is assumed that pre existing capital can be shifted costlessly between countries production decisions in other words decisions about how the existing stock of capital is invested among available technologies determine net foreign investment in the home country however production decisions depend on the distribution of the returns to investments in various technologies whereas this paper analyzes an issue which has always been of considerable interest in the field of international finance it uses a different framework from that used in most of the literature on net capital flows it recognizes explicitly the role of risk as a determinant of net foreign investment 4 because political risk is not modeled explicitly this paper constitutes only a first attempt at understanding the determinants of net foreign investment political risk must play a significant role as a determinant of net foreign investment because net university of rochester i am grateful to the members of the international finance seminar at the university of rochester to jorge de macedo ron jones don lessard and especially pat reagan for useful conversations and comments and to the center for research in government policy and business for financial support net foreign investment in the domestic country is understood to mean the difference between total wealth invested in the domestic country and domestic wealth it follows that net foreign investment is a stock and not a flow international economists would call net foreign investment the

the dynamics of organizational status this paper examines the growth and decline of organizational status it is argued that an organization s status is determined by two factors past performance outcomes and the status of the organization s affiliates the better the past performance outcomes and the higher the status of the affiliates the greater the organization s growth in status this basic proposition is tested in an examination of status changes among investment banks in the non investment grade market between 1981 and 1987 implications and extensions are discussed in the conclusion copyright 1996 by oxford university press

an empirical examination of the form of the relationship between multinationality and performance this paper reports findings from a study that systematically evaluated the form of the relationship between multinationality and performance in contrast to most of the prior conceptualizations that rely on linear monotonic models of the linkage this study examined a curvilinear model that addresses both the costs and benefits associated with multinationality it used time series techniques to capture both the static and dynamic components of the relationship results show that increasing levels of multinationality bring significant performance benefits up to a certain optimum level beyond which benefits begin to decelerate while costs accelerate

asset pricing in partially segmented markets evidence from the finnish market this paper analyzes asset pricing in a partially segmented market where citizens of a small country are allowed to hold only their domestic securities whereas the rest of the investors foreigners are essentially allowed to hold all securities in this market setting it may occur that the citizens of the small country are willing to pay less for their domestic securities than are the foreign investors the paper derives equilibrium required rates of return for different investors in this market setting which perfectly occurred in finland and tests this equilibrium model using data from the finnish stock market empirical results are consistent with the hypotheses derived from the model several studies see e g solnik 1974a and grauer and hakansson 1987 have shown that investors should diversify internationally as by so doing they can reduce the risk of their portfolio without lowering the expected return this implies that if the citizens of a certain country are by legal restrictions prohibited from holding foreign securities they may require a higher rate of return on the domestic securities than the foreign investors do this may happen because the domestic investors cannot diversify away the specific country risk in the same way that the foreign investors can thus if we could observe the prices which the foreign and domestic investors are willing to pay for these domestic securities we would expect them to differ because of this diversification effect the finnish law prohibited finnish investors from investing in foreign securities until 1986 while simultaneously allowing foreign investors to own up to 20 of the shares of any finnish company moreover since 1984 the helsinki stock exchange hse has separately quoted the prices for the unrestricted shares which can be owned both by foreign and domestic investors and for the restricted shares owned solely by domestic investors thus the market setting depicted in the previous paragraph occurred perfectly in finland during the years 1984 and 1985 in this paper our objective is to develop and test an asset pricing model which takes into account the legal restrictions in the finnish stock market in section i we specify the market structure in the finnish stock market in more detail by explaining the relevant legal restrictions affecting the market we also present some descriptive statistics on the prices of the restricted and the unrestricted on

from the editors explaining theoretical relationships in international business research focusing on the arrows not the boxes distinctive features of articles accepted by the journal of international business studies are that they are multidisciplinary in scope and interdisciplinary in content and methodology and they make a substantial theoretical contribution to international business studies failure to meet this last requirement is an often cited reason given by reviewers for article rejection sometimes reviewers mean that a manuscript does not conform to the dominant paradigm in that it is not the next logical step in the study of a phenomenon or they mean that there is little if any integration of several theories used to explain a phenomenon however perhaps the most common underlying meaning when reviewers cite lack of a theoretical contribution for rejection is that the nature of the relationships proposed is not well explained while the first two meanings may be influenced by the specific discipline or methodology involved this final one is not in this editorial we provide a set of guidelines that authors can use to ensure that their paper meets the standard of explaining the logic of the relationships they propose

decomposing technical change within the conventional neoclassical framework a distinction is sometimes made between productaugmenting and factor augmenting technical change a parallel distinction is commonly made between embodied and disembodied technical change with the former associated with factor and the latter with product augmentation disembodied change is commonly assumed to arise from increases in the stock of knowledge independently of the characteristics of the inputs used while embodied change relates to increases in the efficiency of inputs that is labor skills or the productivity of physical capital unfortunately this distinction is ambiguous changes in the efficiency of the inputs used are usually accompanied indeed made possible by increases in knowledge and conversely increases in the stock of knowledge often favor some inputs more than others including the capital goods of one vintage relative to those of another notwithstanding the ambiguity the concept of embodiment has intuitive appeal and this partly explains the focus on decomposing the sources of technical change that followed solow s 6 seminal paper but by the late 1960s a reader of the literature might have concluded that such decomposition was impossible for with merely time series data on inputs and output product augmenting and factor augmenting technical change are empirically indistinguishable in an important paper hall 3 showed that with data on used equipment prices and the interest rate embodied technical change and the deterioration function can in principle be calculated however the paucity of data on the price of used capital goods has allowed little progress in this direction the new longitudinal research database created by the u s bureau of the census now permits still another approach to the estimation of embodied technical change associated

labour and capital saving technical change in telecommunications the australian telecommunications sector is being improved and extended through substantial recent investment in intelligent technology such as digital switching fibre optics satellite and cellular transmission and the internet these technologies are being progressively integrated with technology from the broadcasting computer and electronics industries providing a unified information infrastructure for information transmission and processing technological progress embodied in new equipment has the effect of increasing the efficiency of the factors of production such efficiency increases can be biased towards a particular factor for instance the impact of labour augmenting technical change is a decline in the cost of labour per unit of production when such biases are apparent the relativity between the costs of labour and capital per unit of production is changed in the longer term technical change can impact on the rate of employment growth and also on the rate of capital accumulation in th

cultural diversity and the performance of multinational firms we test the hypothesis that culturally related international diversification will have a positive impact on firm performance and that the opposite will be true for culturally unrelated globalization cultural diversity for fortune 500 firms was used to predict performance over a ten year period 1985 1994 controlling for several organizational and industry characteristics regression tests using nine indicators of cultural diversity revealed no significant cultural effects alternate interpretations are offered

real options in multinational corporations organizational challenges and risk implications in this study we investigate how multinationality affects firms risk levels our investigation builds on the idea from real options theory that international operations offer switching options to multinational corporations yet we also emphasize different sources of coordination costs that can mitigate the benefits of operational flexibility the findings from tobit models accounting for self selection underscore the importance of unobserved heterogeneity in the relationships between international investments and risk levels consistent with the coordination costs surrounding international operations we find that the relationship between multinationality and downside risk is curvilinear risk first declines and then increases as a firm s portfolio of international investments becomes extensive in addition downside risk is an increasing function of the average cultural distance between a firm s home base and the host countries in which its foreign subsidiaries operate

cost structure and technological change of local public transport the kaohsiung city bus case this study has developed a translog cost function for the kaohsiung city bus kcb to analyse its cost structure and economic characteristics based on monthly data over the time period from january 1996 to december 2000 the empirical results reveal that economies of density in the provision of bus services in kaohsiung do prevail the estimated marginal cost which is less than the average cost but greater than the current bus fare indicates that the subsidy is necessary due to the existence of returns to density rtd the kcb could obtain cost saving benefits by extending its output scale the kcb production technology is also not neutral the effects of technological change on the kcb costs suggest that over the period 1996 2000 technological progress did lead to cost saving the pure productivity growth rate increased from 0 45 in 1998 to 3 in 2000

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

international investment barriers in general equilibrium abstract this paper examines quantitative international investment barriers in a general equilibrium model the constraints force otherwise similar agents to hold different portfolios of risky assets we show that this induces lending and borrowing this in turn instroduces a hedging motive against shifts in the interest rate the factors affecting agents portfolio choice the allocation of capital across countries as well as the interest rate are charcterized we conjure that the equilibrium world interest rate will be lower in the constrained situations than with free capital flows

growth accounting when technical change is embodied in capital this paper revisits the hypothesis that technical change is embodied in capital it extends old results to make them more relevant to the contemporary debates about the adjustment of investment goods for quality change and about the role of embodied technical change as a source of economic growth it is shown that the failure to adjust capital for quality change has the effect of suppressing the quality effects into the conventional total factor productivity residual and it is found that approximately 20 percent of the residual growth of quality adjusted output could be attributed to embodied technical change copyright 1992 by american economic association
