money and capital abstract the effects of money anticipated inflation on capital formation is a classic issue in macroeconomics previous papers adopt reduced form approaches putting money in the utility function or imposing cash in advance but using otherwise frictionless models we follow instead a literature that tries to be explicit about the frictions making money essential this introduces new elements including a two sector structure with centralized and decentralized markets stochastic trading opportunities and bargaining these elements matter quantitatively and numerical results differ from findings in the reduced form literature the analysis also reduces a gap between microfounded monetary economics and mainstream macro

labor force participation interest rate shocks and unemployment dynamics in emerging economies abstract emerging economies emes have highly volatile unemployment and real wages standard models with interest rate shocks can generate higher unemployment volatility but still fall quantitatively short of matching the empirical volatility of unemployment a small open economy search model with endogenous participation and self employment a feature of emes generates 90 percent of the volatility of unemployment in the data highly volatile wages and quantitatively consistent cyclical aggregate dynamics amid productivity and interest rate shocks of plausible magnitudes endogenous participation amplifies shocks and plays a critical role in overcoming a key limitation of standard search models for emes

opening the grey box social communities knowledge and culture in acquisitions international acquisitions are today the most important foreign direct investment vehicle and the ensuing integration processes are notoriously fraught with problems we situate discuss and develop the main results of an early study in the knowledge based view tradition the award winning bresman birkinshaw and nobel 1999 article to enhance and develop the central contributions regarding social communities knowledge and culture we use the metaphor of unpacking the grey box we argue that heavy socialization is a rational learning strategy even if the acquirer aims at appropriating the target s technology or wishes to impose its dominant logic

debt leases taxes and the endogeneity of corporate tax status we provide evidence that corporate tax status is endogenous to financing decisions which induces a spurious relation between measures of financial policy and many commonly used tax proxies using a forward looking estimate of before financing corporate marginal tax rates we document a negative relation between operating leases and tax rates and a positive relation between debt levels and tax rates this is the first unambiguous evidence supporting the hypothesis that low tax rate firms lease more and have lower debt levels than high tax rate firms many theories of capital structure imply that all else equal the incentive to use debt financing increases with a firm s marginal tax rate due to the tax deductibility of interest expense e g modigliani and miller 1963 deangelo and masulis 1980 conversely leasing models generally predict that firms with low marginal tax rates employ relatively more leases than do firms with high marginal tax rates the logic behind the leasinlg prediction is that leases allow for the transfer of tax shields from firms that cannot fully utilize the associated tax deduction lessees to firms that can lessors e g myers dill and bautista 1976 smith and wakeman 1985 ross westerfield and jaffe 1996 despite these straightforward predictions empirically testing for tax effects is difficult because a spurious relation exists between the financing decision and many commonly used tax proxies specifically both interest expense and lease payments are tax deductible thus a firm that finances its operations with debt or leases reduces its taxable income potentially lowering its expected marginal tax rate if not properly addressed this endogeneity of the tax rate can bias an experiment in favor of finding a negative

optimal regulation under fixed rules for income distribution abstract it is by now well known that if arbitrary lump sum transfers are feasible then the optimal regulation of firms involves marginal cost pricing here we consider optimal regulation in an economy in which lump sum taxation is possible but the income distribution is in some sense fixed we show that under certain conditions production efficiency and marginal cost pricing are desirable in general however this need not be the case in an economy with increasing returns it is possible that the second best utility possibility frontier is strictly dominated by the pareto frontier and none of the marginal cost pricing equilibria lie on the second best frontier

dynamic inefficiency in decentralized capital markets abstract we study the efficiency implications of bargaining in frictional capital markets in which firms match bilaterally with dealers in order to buy or sell capital we show how two of the distinguishing characteristics of capital ownership and the intertemporal nature of investment give rise to a dynamic inefficiency firms that anticipate buying capital in the future overinvest because this increases their outside option of no trade in negotiations with dealers in the future thereby lowering the bargained purchase price vice versa firms that anticipate selling capital in the future strategically underinvest because this increases the bargained sale price if the only motive for trade is capital depreciation there is overinvestment with stochastic productivity high productivity firms underinvest and low productivity firms overinvest in equilibrium the inefficiency interacts with the externality from dealer entry and implies that no bargaining power achieves the constrained efficient allocation we propose a regressive tax on capital that can restore efficiency finally we calibrate the model to data on physical capital markets and show that depending on bargaining power the welfare loss from the inefficiency can be large

the effects of oil price shocks in a new keynesian framework with capital accumulation the economic implications of oil price shocks have been extensively studied since the 1970s despite this huge literature no dynamic stochastic general equilibrium model was available that captures two well known stylized facts 1 the stagflationary impact of an oil price shock together with 2 the influence of the energy productivity of capital on the depth and length of this impact we build estimate and simulate a new keynesian model with capital accumulation which takes the case of an economy where oil is imported from abroad and where these stylized facts can be accounted for moreover the bayesian estimation of the model on the us economy 1984 2007 suggests that the output elasticity of oil might have been above 10 stressing the role of oil use in us growth at this time finally our simulations confirm that an increase in energy efficiency significantly attenuates the effects of an oil shock a possible explanation of why the third oil shock 1999 2008 did not have the same macro economic impact as the first two ones

national cultural distance and cross border acquisition performance previous theoretical research has argued that national cultural distance hinders cross border acquisition performance by increasing the costs of integration this article tests the alternative hypothesis that national cultural distance enhances cross border acquisition performance by providing access to the target s and or the acquirer s diverse set of routines and repertoires embedded in national culture using a multi dimensional measure of national cultural distance and controlling for other effects we examine a sample of 52 cross border acquisitions that took place between 1987 and 1992 and find a positive association between national cultural distance and cross border acquisition performance

learning from failure towards an evolutionary model of collaborative ventures this paper reports on a longitudinal case study of the interaction between two partners to a failed international joint venture we develop a model of the collaboration process in partnership and alliances based on earlier work by ring and van de ven 1994 and by doz 1996 we employ a series of events that occurred in the course of the relationship as the unit of analysis in order to trace the interactions between the partners and to explicate the impact that external shocks have on their perceptions of efficiency and equity the impact of these events as well as the responses they elicit on the quality of the relationship and vice versa are also considered we find that the partners assessments cause them to either engage in renegotiation of the terms of the contract or to modify their behavior unilaterally in an attempt to restore balance to the relationship the process feeds back until a new mutual understanding of equity is restored or else the relationship deteriorates gradually until a point when the venture is dissolved we conclude that positive feedback loops are critical in the evolutionary process that relationship quality is both an outcome and a mediating variable and that procedural issues are critical from the start in fostering a climate for positive reinforcement and the building of mutual trust and confidence in the relationship

investments holdup and the form of market contracts the authors analyze incomplete contracts to induce efficient investment with exogenous switching costs fixed price contracts are efficient generate some rigidity in prices are renegotiated intermittently by possibly small amounts and when inflation is positive generate asymmetric responses to shocks all consistent with evidence on prices and wages with two sided specific investments efficiency requires prices to have sufficient escalator clauses to avoid renegotiation as observed in many long term contracts a third case with one sided specific investments can generate take or pay contracts and explain why firms sometimes pay for specific investments that appear to benefit employees directly

organizational design and technology choice under intrafirm bargaining comment the authors consider a wide number of applications of an intrafirm bargaining game within organizations where employees and the firm engage in wage negotiations under their presumption that contracts cannot bind employees to the organization the resulting stable wage and profit profiles give rise to an objective function for the firm that places weight on inframarginal profits in an economically significant manner the authors in turn employ this methodology to explore applications of organizational design hiring and capital decisions training and cross training the importance of labor and asset specificity managerial hierarchies preferences for unionization responses to competition and internal capital budgeting copyright 1996 by american economic association

job destruction and propagation of shocks this paper considers propagation of aggregate shocks in a dynamic general equilibrium model with labor market matching and endogenous job destruction cyclical fluctuations in the job destruction rate magnify the output effects of shocks as well as making them much more persistent interactions between capital adjustment and the job destruction rate play an important role in generating persistence propagation effects are shown to be quantitatively substantial when the model is calibrated using job flow data incorporating costly capital adjustment leads to significantly greater propagation

existence of marginal cost pricing equilibria in economies with several nonconvex firms this paper considers a general equilibrium model of an economy where some firms may exhibit increasing returns to scale or more general types of nonconvexities the firms are instructed to follow the standard marginal cost pricing rule or to fulfill the first order necessary conditions for profit maximization a general existence theorem of equilibria is proved in the case of an arbitrary number of firms no assumption is made to imply the aggregate productive efficiency of equilibria a condition that must be excluded in the nonconvex case the failure of the competitive mechanism in the presence of increasing returns to scale has been recognized since marshall 1920 and the search for alternative mechanisms has resulted in the so called theory of marginal cost pricing this theory was developed by allais 1953 hotelling 1938 lange 1936 lerner 1936 pigou 1932 to remain in the thirties and forties but has a long history dating back to the discussion on public utility pricing by dupuit 1844 it states that an optimum of welfare corresponds to the sale of everything at marginal cost hotelling 1938 this statement of the second welfare theorem has since been formulated at a high level of generality starting with the work by guesnerie 1975 and more recently by bonnisseau and cornet 1988b cornet 1986 1988a b c khan and vohra 1987 1988 quinzii 1986 none of these papers however is concerned with the existence of equilibria this has been considered in the past ten years by beato 1979 1982 beato and mas colell 1985 brown and heal 1982 brown et al 1986 cornet 1982 dierker guesnerie and neuefeind 1985 mantel 1979 and more recently by bonnisseau bonnisseau cornet kamiya and vohra in the special issue of the journal of mathematical economics 1988 on general equilibrium theory and increasing returns the purpose of this paper is to provide a general existence theorem for an economy with an arbitrary number of convex and nonconvex producers which may exhibit increasing returns to scale or even more general types of nonconvexities in our model a the consumers maximize their preferences subject to their budget constraints b the convex producers maximize their profits while the nonconvex producers are instructed to follow the marginal pricing rule i e they

intra firm bargaining under non binding contracts we present a new methodology for studying the problem of intra firm bargaining based on the notion that contracts cannot commit the firm and its agents to wages and employment we develop and analyse a general non cooperative multilateral bargaining framework between the firm and its employees and consider outcomes which are immune to renegotiations by any party equilibrium firm profits are characterizable as both a weighted average of a neo classical non bargaining firm s profits and a generalization of shapley value for a corresponding cooperative game furthermore the resulting payoffs induce economically significant distortions in the firm s input and organizational design decisions

connections to distant knowledge interpersonal ties between more and less developed countries less developed countries benefit from being connected to technologically and economically advanced countries the well documented mechanisms for this cross national flow of knowledge all involve interfirm connections such as trade foreign direct investment fdi and alliances we examine the potential of a different mechanism interpersonal ties abroad that has only recently become practicable owing to advances in communication and transportation technologies globalization and increased migration we investigate when business knowledge obtained from interpersonal ties in more developed countries is more useful than locally sourced knowledge using a sample of south african managers we find that knowledge from more developed countries is not always more useful rather overseas knowledge is preferable when novel and accessible that is when new to the industry knowledge is needed when there is already a strong tie and when the knowledge does not involve a long discussion conversely local knowledge is preferable when new to the industry knowledge is not needed when the interpersonal tie is a weak tie and when a longer discussion is warranted this study demonstrates the value of connections between individuals in countries at different levels of development as sources of useful knowledge and suggests that international business research will benefit from exploring further the networks of individuals in addition to those of firms

mars venus marriages culture and cross border m a using a sample of over 800 cross border acquisitions during 1991 2004 we find that contrary to general perception cross border acquisitions perform better in the long run if the acquirer and the target come from countries that are culturally more disparate we use mainly the hofstede measure of cultural dimensions to measure cultural distance but also examine alternative proxies the positive relationship of performance to cultural distance persists after controlling for several deal specific variables and country level fixed effects and is robust to alternative specifications of long term performance cash and friendly acquisitions tend to perform better in the long run there is also some evidence of synergies when acquirers are from stronger economies relative to the targets

a coasean general equilibrium model of regulation abstract although marginal cost pricing is necessary for welfare maximization firms that produce under conditions of decreasing average cost incur losses if they price at marginal cost in this paper the coase two part tariff is extended to several cases of common costs by assessing surplus in order to recover the losses of the regulated natural monopolist the existence of equilibria in these cases is demonstrated three models are considered in the context of an arrow debreu private ownership economy a model of the regulated monopolist who charges hookups to both households and firms who use the good a model of the regulated natural monopolist who is allowed to make positive economic profit and finally a model where two or more monopolists are under the control of a single regulator

r d co practice and reverse knowledge integration in multinational firms this paper contributes to the developing literature on the management of distributed innovation in multinational firms we focus on a specific organizational mechanism r d co practice which we believe is an important facilitator of knowledge integration in multinationals with global innovation strategies in our formulation r d co practice joint technical activities between units increases levels of absorptive capacity and social capital among participating units thus increasing the likelihood that they will share knowledge at future time periods we find strong support for this hypothesis through an empirical analysis of reverse subsidiary to headquarters knowledge integration in two sectors automotive and pharmaceuticals over a 21 year period

the underdetermined knowledge based theory of the mnc in this note we revisit two core propositions of the knowledge based view of the firm found in the seminal work of kogut and zander 1 that multinational corporations mncs exist because transfers and re combinations of knowledge occur more efficiently inside mncs than between mncs and third parties and 2 that the threat of opportunism is not necessary although it may be sufficient to explain the existence of the mnc their knowledge based view shifted the conceptualization of the firm from an institution arising from market failure and transaction costs economizing to a progeny of superior knowledge governance we question these conclusions arguing that firms are but one of the many types of epistemic communities possessing and nurturing procedural norms identity and the cognitive linguistic and reflexive attributes conducive to efficient exchange and re combination of knowledge among their members important insights may be gained by applying the concept of epistemic communities implicit in the knowledge based perspective beyond firm level hierarchies journal of international business studies 2011 42 427 435

knowledge market failure and the multinational enterprise a reply debate is an indication that an issue warrants discussion the comments of james love and donald mcfetridge in this issue are fine statements that articulate a received wisdom their comments differ with each other and these differences remind us that there is less consensus in our understanding of internalization and transaction costs than commonly supposed if we do not address all of the commentators specific points it is not for lack of appreciation but because it is our belief that a fuller vision of the terrain already mapped and that which is yet uncharted would provide a more useful basis for exploration and discovery a listing of issues is the task of a referee while a published debate might perform a useful task by laying out the contours of the research tradition and future

a search based theory of the on the run phenomenon we propose a model in which assets with identical cash flows can trade at different prices infinitely lived agents can establish long positions in a search spot market or short positions by first borrowing an asset in a search repo market we show that short sellers can endogenously concentrate in one asset because of search externalities and the constraint that they must deliver the asset they borrowed that asset enjoys greater liquidity a higher lending fee specialness and trades at a premium consistent with no arbitrage we derive closed form solutions for small frictions and provide a calibration generating realistic on the run premia

measuring innovative performance is there an advantage in using multiple indicators abstract the innovative performance of companies has been studied quite extensively and for a long period of time however the results of many studies have not yet led to a generally accepted indicator of innovative performance or a common set of indicators so far the variety in terms of constructs measurements samples industries and countries has been substantial this paper studies the innovative performance of a large international sample of nearly 1200 companies in four high tech industries using a variety of indicators these indicators range from r d inputs patent counts and patent citations to new product announcements the study establishes that a composite construct based on these four indicators clearly catches a latent variable innovative performance however our findings also suggest that the statistical overlap between these indicators is that strong that future research might also consider using any of these indicators to measure the innovative performance of companies in high tech industries

the revealed preferences of high technology acquirers an analysis of the innovation characteristics of their targets this paper investigates whether acquisitions involving public high technology firms are best understood in terms of acquirers taking over firms with superior innovation performance to access their assets or acquiring firms with inferior innovation performance to turn them around innovation performance is proxied by r d intensity r d expenditure over assets patent intensity patents per us million of assets i e the r d productivity of a firm s assets and the patent stock i e the accumulated r d output we find substantial overlaps between target and non acquired firm characteristics nevertheless targets have a relatively high r d intensity and a large patent stock which is consistent with acquirers targeting firms with a superior innovation performance however these targets have significantly lower pre acquisition patent intensity and hence a lower r d productivity the targets are also experiencing weak financial performance our results are consistent with a selection process in which acquirers seek out firms that have a superior past innovation performance but that are failing in terms of recent r d productivity and financial performance a comparison of the performance of the targets with their acquirers reinforces this conclusion

price discovery in illiquid markets do financial asset prices rise faster than they fall we study price discovery in municipal bonds an important otc market as in markets for consumer goods prices rise faster than they fall round trip profits to dealers on retail trades increase in rising markets but do not decrease in falling markets further effective half spreads increase or decrease more when movements in fundamentals favor dealers yield spreads relative to treasuries also adjust with asymmetric speed in rising and falling markets finally intraday price dispersion is asymmetric in rising and falling markets as consumer search theory would predict in a wide variety of consumer markets prices for retail goods rise faster than they fall 1 this asymmetric price adjustment referred to as rockets and feathers is generally understood by economists to be inconsistent with perfect competition between sellers sellers appear to exploit local market power due to the search frictions that their customers face we document asymmetric price adjustment in a major over the counter otc financial market using a comprehensive sample of all trades in municipal bonds over a 5 year period we provide evidence that the asymmetric price adjustment is associated with opportunistic timing by the broker dealers who intermediate trades in the market movements in fundamentals that increase spreads earned by broker dealers are reflected quickly in prices while prices respond more slowly to changes that reduce their spreads further the asymmetries are more pronounced in states where tax treatment of the bonds would induce market segmentation we also document asymmetries in withinday price dispersion as implied by theoretical models of rockets and feathers price adjustments based on costly consumer search and learning

two part marginal cost pricing equilibria with n firms sufficient conditions for existence and optimality the authors explore the interactions among firms with increasing returns regulated to break even by pricing with two part tariffs they provide conditions for existence and for efficiency of general equilibria with n firms this involves finding hookup fees that are voluntarily paid and cover the firms losses from marginal cost pricing a problem that because of both substitution and income effects is complicated by multiple firms using two part tariffs but that must be solved to ensure the continuity of demands necessary to prove break even equilibria exist copyright 1993 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

are the extent and effect of psychic distance perceptions symmetrical in cross border m as evidence from a two country study the concept of psychic distance has several entrenched assumptions that have not been put to sufficient systematic scrutiny we address this gap by investigating the assumptions of symmetry i e whether psychic distance from country a to country b is the same as that from country b to country a and discordance i e whether differences in psychic distance between two countries always lead to lack of fit of psychic distance in cross border mergers and acquisitions we propose a new framework which differentiates between the extent i e the degree to which two countries are perceived to be similar different and effects i e the degree to which distance perceptions create favorable or unfavorable attitudes and responses of psychic distance perceptions we argue that relative status positions affect extent and effects of psychic distance to test our predictions we collected data through policy capturing studies in sweden and china our findings reveal that both the extent and the effects of psychic distance perceptions are asymmetric we also found that psychic distance perceptions create unfavorable favorable attitudes among swedish chinese respondents toward chinese swedish acquirers our follow up examination confirms that relative status positions are a key driver of these results

on the inefficiency of two part tariffs the partial equilibrium literature on two part tariffs suggests that if a commodity is produced under increasing returns efficiency can be achieved through marginal cost pricing and a suitable choice of entry fees fixed charge which may vary from consumer to consumer we show that this partial equilibrium intuition cannot be extended beyond some special cases even with a consumer specific fixed charge it is possible that none of the equilibria yield pareto efficiency furthermore it may be impossible to achieve pareto efficiency through any specification of taxes which are levied solely to cover losses hotelling 1939 and lerner 1944 among others see for example the surveys by ruggles 1949 1950 argued that firms operating under increasing returns to scale should be regulated to equate their marginal cost to the price of the output and the resulting losses financed through lump sum taxes being concerned primarily with efficiency issues the proponents of the marginal cost pricing principle did not advocate any particular distribution of the lump sum taxes among the consumers after the ensuing debate see for example ruggles 1950 there seems to have been a general agreement that marginal cost pricing is necessary for efficiency while admitting this coase 1946 presented an illuminating analysis of the drawbacks of what he called the hotelling lerner solution and also proposed an alternative solution it will be useful to begin by briefly recalling coase s criticism of the hotelling lerner solution apart from the practical problem of collecting lump sum taxes he emphasized two distinct drawbacks of the hotelling lerner scheme he claimed that this solution would not necessarily guarantee efficiency in the sense that it might lead to a marginal cost pricing equilibrium in which a positive amount of the commodity was produced whereas it would be better not to produce the commodity at all this can be restated simply as the argument that in the presence of non convexities marginal conditions need not guarantee global optimality there may be several marginal cost pricing equilibria some efficient and some inefficient as such this phenomenon can hardly be ruled out coase s second objection to the hotelling lerner solution was that it could effectively alter the income distribution if for instance a lump sum tax was imposed on all the consumers but only some of them consumed the commodity produced by the firm operating under increasing returns to scale then there would effectively be a redistribution in favour of those who consumed this subsidized commodity it was natural to keep the issue of efficiency separate from that of equity and coase argued that the hotelling lerner solution

holdups and overinvestment in capital markets abstract this paper considers a decentralized capital market characterized by trading frictions in which firms and suppliers need to make investment decisions before meeting with each other and bargaining over the price of capital the resulting holdup problem provides firms with a strategic incentive to overaccumulate capital so as to reduce their marginal productivity and thus the bargained price in equilibrium this strategic incentive can outweigh the usual distortionary effects of holdup problems that on their own would lead to underinvestment thus resulting in the economy to overinvest in a setting with both capital and labor the holdup problem in capital markets interacts with holdup problems in labor markets this presents firms with a trade off that has non trivial equilibrium effects and that depending on the substitutability of capital and labor and the firm s bargaining power in each market can mitigate or exacerbate the overinvestment result

a knowledge based theory of the firm the problem solving perspective in this paper we develop a knowledge based theory of the firm while existing knowledge based theory focuses on the efficiency of hierarchy in economizing on knowledge exchange we develop a theory of the firm that focuses on the efficiency of alternative organizational forms ingenerating knowledge or capability our theory begins with the problem as the basic unit of analysis arguing that a problem s complexity influences the optimal method of solution search and the optimal means of organizing that search the distinguishing feature that differentiates among organizational alternatives is the different way each resolves conflict over the selection of solution trials that is the way it chooses the path of search our theory predicts that efficiency demands that these governance alternatives be matched in a discriminating way to problems based on their associated benefits and costs in governing solution search thus our theory is among the first to simultaneously treat both the boundary choice i e internal versus external and the choice among alternative internal approaches to organizing

knowledge transfer in international acquisitions this paper reports on a multimethod study of knowledge transfer in international acquisitions using questionnaire data we show that the transfer of technological know how is facilitated by communication visits meetings and by time elapsed since acquisition while the transfer of patents is associated with the articulability of the knowledge the size of the acquired unit and the recency of the acquisition using case study data we show that the immediate post acquisition period is characterized by imposed one way transfers of knowledge from the acquirer to the acquired but over time this gives way to high quality reciprocal knowledge transfer

money and capital as competing media of exchange we construct a model where capital competes with fiat money as a medium of exchange and we establish conditions on fundamentals under which fiat money can be both valued and socially beneficial when the socially efficient stock of capital is too low to provide the liquidity agents need they overaccumulate productive assets to use as media of exchange when this is the case there exists a monetary equilibrium that dominates the nonmonetary one in terms of welfare under the friedman rule fiat money provides just enough liquidity so that agents choose to accumulate the same capital stock a social planner would

distance without direction restoring credibility to a much loved construct in this commentary we build on shenkar s 2001 award winning critique of cultural distance arguing that most distance constructs in fact suffer the same flaws because they oversimplify the relationship between countries overlook their subjective and context specific nature and pay insufficient attention to the mechanisms through which distance operates the idea of distance however has intrinsic value moreover its considerable appeal and undeniable effectiveness have made it a well entrenched construct therefore we see merit in redressing its weaknesses and offer several suggestions for doing so these include allowing for the influence of firm level characteristics that either moderate the effects of distance or render distance at least in part subjective with varying consequences for different mnes maintaining directionality by distinguishing between distance and the tendency toward a particular characteristic and acknowledging asymmetry and conceptualizing the effects of distance and the mechanisms through which it operates more carefully by drawing on concepts and measures from a variety of disciplines by offering ways to strengthen both its theoretical foundations and measurement we hope to enhance the usefulness of one of international business theory s most central constructs

external technology sourcing through alliances or acquisitions an analysis of the application specific integrated circuits industry in today s turbulent business environment innovation is the result of the interplay between two distinct but related factors endogenous r d efforts and quasi external acquisition of technology and know how given the increasing importance of innovation it is vital to understand more about the alternative mechanisms such as alliances and acquisitions that can be used to enhance the innovative performance of companies most of the literature has dealt with these alternatives as isolated issues companies however are constantly challenged to choose between acquisitions and strategic alliances given the limited resources that can be spent on research and development this paper contributes to the literature because it focuses on the choice between innovation related alliances and acquisitions we focus on the question of how the trade off between strategic alliances and acquisitions is influenced by previous direct and indirect ties between firms in an industry network of interfirm alliances we formulate hypotheses pertaining to the number of direct ties between two companies their proximity in the overall alliance network and their centrality in that network in so doing we distinguish between ties that connect firms from the same and from different industry segments and those that connect firms from the same or from different world regions these hypotheses are tested on a sample of strategic alliances and acquisitions in the application specific integrated circuits asic industry the findings show that a series of strategic alliances between two partners increases the probability that one will ultimately acquire the other whereas previous direct contacts tend to lead to an acquisition this is not true of previous indirect contacts which increase the probability that a link between the companies once it is forged takes the form of a strategic alliance in the case of acquisitions firms that are more centrally located in the network of interfirm alliances tend to be acquirers and firms with a less central position tend to become acquired these findings underscore the importance of taking previously formed interfirm linkages into account when explaining the choice between strategic alliances and acquisitions as these existing links influence the transaction costs associated with both alternatives

international acquisition success social community and dominant logic dimensions international acquisitions intended to achieve knowledge transfers and improvements of innovation capacity can only be successful if the acquirer devotes balanced attention to a building a unified social community and b achieving requisite commonality in dominant logic the balance between these two dimensions of success depends on the activity class considered in some activity classes imposing the acquiring firm s dominant logic will be dysfunctional and therefore the post acquisition managerial focus may need to shift towards social community building bresman birkinshaw and nobel s 1999 acclaimed jibs paper should be commended for identifying the social community dimension as a critical driver of international acquisition success

determinants of cross national knowledge transfer and its effect on firm innovation this study examines the determinants of international knowledge flow from a resource based perspective it evaluates the impact of cross national knowledge transfer on firm innovative performance based on 56 027 us patents owned by 53 selected firms in the us based pharmaceutical industry the results suggest that innovative performance is a curvilinear function of the international knowledge content used by a firm to innovate as hypothesized it was found that at 1 low and moderate levels of international knowledge content a firm s strategy to transfer international knowledge improves its innovative performance and at 2 higher levels of international knowledge content there are diminishing marginal returns to transferring knowledge from overseas

the macroeconomics of specificity specific quasi rents arise in a variety of economic relationships and are exposed to opportunism unless fully protected by contract rent appropriation has important macroeconomic consequences resources are underutilized factor markets are segmented production suffers from technological sclerosis job creation and destruction are unbalanced recessions are excessively sharp and expansions run into bottlenecks while depending on the shock expansions may require reinforcement or stabilization recessions should typically be softened in the long run institutions may evolve to alleviate the problem by balancing appropriation technology choice will also be affected with the appropriated factor partially excluding the other from production to reduce appropriation

capital reallocation and liquidity this paper studies the cyclical properties of capital reallocation and the frictions which inhibit such reallocation we show that the amount of capital reallocation and the benefits to reallocation vary at the business cycle frequency the amount of capital reallocation is procyclical in contrast the benefits to capital reallocation appear countercyclical we measure the amount of reallocation using data on flows of capital across firms and the benefits to capital reallocation using several measures of the cross sectional dispersion of the productivity of capital we then study a calibrated model of an economy where capital reallocation is costly and impute the cost of reallocation which is consistent with the amount of and benefits to reallocation in the data we find that the cost of reallocation needs to be substantially countercyclical to be consistent with the observed joint cyclical properties of reallocation and productivity dispersion the cyclical variation in this cost is interpreted as variation in the liquidity of capital broadly defined since physical costs are unlikely to vary countercyclically

joint r d in low carbon technology development in china a case study of the wind turbine manufacturing industry abstract china faces the dual challenges of climate change and increased energy demand these challenges in turn increase the demand for wind energy development along with rapid growth in manufacturing capacity chinese companies have aspired to increase their innovation capacity in order to enhance their competitiveness in the market joint research and development r d is an attractive path for chinese companies striving to advance their r d capacity this paper examines joint r d between chinese wind turbine manufacturing companies and foreign design firms assessing the performance of joint r d activities in china using the structure conduct performance scp framework the study found that joint r d has improved chinese companies technical capacity human resources and financial growth however the effect on chinese companies innovation capacity is still limited because of unequal technical capacities of the two sides in collaboration as well as their preference for augmenting profits rather than technical capacity current joint r d mode is only the extension of licensing mode in wind turbine manufacturing industry

a theory of wages and labor demand with intra firm bargaining and matching frictions this article provides a model of labor market equilibrium with search and within firm strategic bargaining we yield explicit closed form solutions with heterogeneous labor inputs and capital the solution exhibits overemployment we show that higher relative bargaining power for some groups of workers may lead to overemployment relative to other groups with such other groups being underemployed instead if they have a lower relative bargaining power similarly the hold up problem between capitalists and employees does not necessarily lead to underinvestment in physical capital beyond the neo classical analysis firms are the field of several strategic interactions between capital owners and labor between marginal employees and incumbents and more generally between different groups with various bargaining positions within the firm it is usually considered that the bargaining power of workers entails an employment level that is lower than in a competitive labor market and any increase in the bargaining power of workers raises unemployment these results are true for a wide class of models and notably in the now standard framework to analyze unemployment namely search and matching models of pissarides 2000 however stole and zwiebel 1996a 1996b show that the above results are totally changed in the intra firm bargaining model where employees engage in individual wage negotiation with the firm in fact under the assumption that contract incompleteness does not enable either party to commit to future wages and employment decisions they show that intra firm bargaining yields no rent for employees and gives rise to overemployment compared to a competitive labor market the basic idea of stole and zwiebel is that a firm with a diminishing marginal productivity of labor can decrease the bargained wage which increases in the marginal productivity of labor by raising employment in stole and zwiebel s setting firms overemploy strategically up to the point where workers get their reservation wage

knowledge transfer in international acquisitions a retrospective in this retrospective we summarise and discuss the findings of our 1999 jibs paper knowledge transfer in international acquisitions and we consider how research in this area has evolved over the last decade the paper s key contribution was to show how the post acquisition integration process in a sample of three international acquisitions led to the creation of a social community characterised by two way knowledge sharing between the acquirer and acquired companies we discuss how the timing of this publication as an early contribution to the knowledge based perspective on the firm helped its visibility and we consider the boundary conditions around our findings

the double edged sword of cultural distance in international acquisitions this study aims to bring together seemingly contradicting arguments in the literature about the role of cultural distance in international acquisitions we offer a model that postulates that cultural distance relates negatively to international acquisition performance because it taxes integration capabilities during international acquisitions but that cultural distance also elevates the positive association of integration capabilities and international acquisition performance because it provides more learning opportunities that can only be exploited with strong integration capabilities empirical tests with a sample of international acquisitions by 118 us multinational companies provide support for the proposed model on one hand we find that cultural distance impedes understandability of key capabilities that need to be transferred and constrains communication between acquirers and their acquired units bringing about a negative indirect effect on acquisition performance on the other hand we find that cultural distance enriches acquisitions by enhancing the positive effects of understandability and communication on acquisition performance acquirers that can overcome the impeding effects of cultural distance on understanding key capabilities and effective communication appear to reap significant performance gains our study provides initial support for a double edged sword effect of cultural differences on acquisition performance and illustrates the importance of integration capabilities

on marginal cost pricing with given tax subsidy rules we provide an existence proof for generalized marginal cost pricing with given tax subsidy rules the novelty is that our approach allows for economic environments where all the generalized marginal cost pricing equilibria are inefficient in the aggregate an example is recalled in order to suggest how non pathological these environments are

gross credit flows the paper estimates gross credit flows for the u s banking system between 1979 and 1999 and shows that sizable gross flows coexist at any phase of the cycle even within narrowly defined loan categories bank size categories and regional units to investigate the macroeconomic dimensions of gross credit flows the paper studies the cyclical behavior of aggregate credit flows and documents three key cyclical facts first excess credit reallocation is countercyclical for any given rate of change of net credit gross flows are larger in a recession than in a boom second gross credit flows are highly volatile with a cyclical volatility which appears more than an order of magnitude larger than gdp volatility third credit contraction is more volatile than credit expansion furthermore the behavior of gross flows over the 1991 recession suggests that persistent and historically high credit contraction is a key feature of the relatively mild cyclical downturn the results lends some support to aggregate models that emphasize the asymmetric behavior of credit expansion and credit contractions

technological effects of m as in spanish manufacturing this article explores whether mergers and acquisitions m as generate differentiated impacts on the acquiring firms r d expenditures patents granted and product innovations considering m as as a way of foreign expansion we examine whether the technological effects differ between domestic and foreign owned acquirers assuming that the effects on the technological efforts and performance may differ across industries the availability of statistical information for a stable sample of manufacturing companies in spain during the 1990s allows us to follow a dynamic approach to the issue our findings confirm the existence of differentiated effects on technological inputs and outputs across industries as well as diversity between domestic and foreign owned firms involved in m as copyright 2009 the author 2009 published by oxford university press on behalf of associazione icc all rights reserved oxford university press

the genealogy of modern theoretical public economics from first best to second best abstract the development of second best modelling in the seventies has shaped modern theoretical economics the paper discusses some key changes in the economists conceptions the first two sections examine the efficiency equity dilemma the study of non convexities has shown that counterintuitive efficiency enhancing income redistribution might occur the introduction of asymmetric information has shed doubts on virtues of lump sum compensation the last sections focus on the intricate geometry of second best optimisation and the ambiguous value of the signals provided by the price system outside a first best world

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

optimal monetary policy with countercyclical credit spreads we study optimal monetary policy in a new keynesian dynamic stochastic general equilibrium dsge model with a credit channel and relationship lending in banking we show that borrowers bank specific deep habits give rise to countercyclical credit spreads which in turn make optimal monetary policy depart substantially from price stability under both discretion and commitment our analysis shows that the welfare costs of setting monetary policy under discretion with respect to the optimal ramsey plan and of using simpler suboptimal policy rules are strictly increasing in the magnitude of deep habits in credit markets and market power in banking

the macroeconomics of labor and credit market imperfections labour market frictions are not the only possible source of high unemployment credit market imperfections driven by microeconomic frictions and influenced by macroeconomic factors could also be to blame to develop this idea in a simple and tractable macroeconomic model we treat credit and labour market imperfections in a symmetrical way accordingly we introduce specificity in credit relationships and assume that credit to potential entrepreneurs is rationed due to endogenous search frictions in the spirit of diamond 1990 these imperfections mirror job search frictions in the labour market we study the determination of equilibrium unemployment in the presence of credit market frictions both with exogenous and endogenous wages we explore a number of possible extensions endogenous destruction monetary policy and the short run effects of financial liberalization

merging without alienating interventions promoting cross cultural organizational integration and their limitations foreign direct investment particularly cross border mergers and acquisitions can spawn a range of individual level outcomes from cross cultural adjustment and synergistic learning on the positive side to work alienation on the negative unsuccessful navigation of these individual level outcomes leads to failed integration that can seriously affect the realization of desired organizational outcomes such as successful technology transfer knowledge sharing and the general realization of global growth by means of an iterative between methods triangulation the study surfaces cross cultural work alienation as a phenomenon that can limit the overall success of such ventures and identifies interventions that help to promote successful post merger integration

two part marginal cost pricing equilibria existence and efficiency two part tariffs are explored in a general equilibrium model with increasing returns to scale two part marginal cost pricing equilibria are not generally paretoefficient the second fundamental theorem of welfare economics may also fail we introduce a notion of consumer surplus as the willingness to pay for access to the increasing returns good the individuals s hookup charge is set to a fixed fraction of his consumer surplus if aggregate consumer surplus exceeds the losses of the regulated monopoly then exact two part marginal cost pricing equilibria exist further for efficient allocations having positive net surplus the second fundamental theorem of welfare economics holds

externalities and fundamental nonconvexities a reconciliation of approaches to general equilibrium externality modeling and implications for decentralization abstract starrett 1972 33 and boyd and conley 1997 7 approaches to externality modeling are unified by distinguishing between producible and nonproducible public commodities nonconvexities are associated with detrimental producible public commodities but not with nonproducible public commodities in boyd and conley 1997 7 disposability properties costly or costless imply that producible public commodities are either by products e g pollution or joint products e g national defense markets fail for both beneficial and detrimental by products nonconvexities imply that price based equilibria e g pigovian tax equilibrium may not be pareto efficient foley s 1967 1970 17 18 public competitive equilibrium combines price and quantity signals with a unanimity criterion and restores the equivalence between equilibrium and efficiency

holdups and efficiency with search frictions a natural holdup problem arises in a market with search frictions firms have to make a range of investments before finding their employees and larger investments translate into higher wages in particular when wages are determined by ex post bargaining the equilibrium is always inefficient recognizing that capital intensive production relations have to pay higher wages firms reduce their investments this can only be prevented by removing all the bargaining power from the workers but this in turn depresses wages below their social product and creates excessive entry of firms in contrast to this benchmark we show that efficiency is achieved when firms post wages and workers can direct their search toward more attractive offers this efficiency result generalizes to an environment with imperfect information where workers only observe a few of the equilibrium wage offers we show that the underlying reason for efficiency is not wage posting per se but the ability of workers to direct their search toward more capital intensive jobs

too much investment a problem of endogenous outside options this paper shows that when agents on both sides of the market are heterogeneous varying in their costs of investment ex ante investments by firms and workers or buyers and sellers more generally may be too high when followed by stochastic matching and bargaining over quasi rents the overinvestment is caused by the fact that low cost agents by investing more can increase the value of their outside option and thus shift rent away from high cost investors numerical simulations show that overinvestment can occur given parameter values calibrated to oecd labour markets

the boundaries of the firm revisited why do firms exist what is their function and what determines their scope these remain the central questions in the economics of organization they are also central questions for business executives and corporate strategists the worldwide volume of corporate mergers and acquisitions exceeded 1 6 trillion in 1997 it is hard to imagine that so much time effort and investment bankers fees would be spent on adjusting firm boundaries unless there was some underlying economic gain indeed the exceptional levels of merger and acquisition activity over the past two decades are a strong indication that economically significant forces do determine organizational boundaries the study of firm boundaries originated with the famous essay by coase 1937 who raised the question of why we observe so much economic activity inside formal organizations if as economists commonly argue markets are such powerful and effective mechanisms for allocating scarce resources coase s answer was in terms of the costs of transacting in a world of imperfect information when the transaction costs of market exchange are high it may be less costly to coordinate production through a formal organization than through a market in large part thanks to the work of williamson 1975 1985 recent decades have seen a resurgence of interest in coase s fundamental insight that firm boundaries can be explained by efficiency considerations our understanding of firm boundaries has been sharpened by identifying more precisely the nature and sources of transaction costs in different circumstances in the process the focus of

general equilibrium when some firms follow special pricing rules in this paper we study the existence of a general equilibrium in an economy in which some of the firms behave competitively whereas others follow special pricing rules an even casual observation of economic reality confirms the need for the inclusion of price setting firms in the study of general equilibrium models and in fact this has been emphasized in the economic literature for some time we consider this a sufficient justification to present a general equilibrium model which allows for both types of behavior price setting as well as price taking behavior the model to be presented will account for a wide range of price setting rules we however find it appropriate to point out at the start that not all economically relevant price setting rules are covered although our model permits the drawing of useful conclusions for the general equilibrium theory of oligopolistic competition through prices it is not especially designed for that purpose in particular our results are not applicable to the general equilibrium analysis with price making monopolistic firms a subject on which there exists some literature 2 our motivation as well as our modelling options and assumptions are directed to two fields where an increased interest in the theoretical foundations recently could be noticed

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

cultural influences on national rates of innovation abstract the purpose of this research was to examine the effect of the cultural values of individualism power distance uncertainty avoidance and masculinity on national rates of innovation in 33 countries in 1975 and 1980 the study found that rates of innovation are most closely associated with the cultural value of uncertainty acceptance but that lack of power distance and individualism also are related to high rates of innovation this research suggests that nations may differ in their rates of innovation because of the cultural values of their citizens these findings have important implications for managers and policy makers first culture matters countries may not be able to increase their rates of innovation simply by increasing the amount of money spent on research and development or industrial infrastructure they also may need to change the values of their citizens to those that encourage innovative activity this concept in turn suggests that national rates of innovation are driven by more fundamental forces than economic conditions and that societal change may be necessary to make less innovative societies more innovative second the values associated with high national rates of innovation are those that many scholars have long argued are important at the firm level an acceptance of uncertainty appears to be necessary probably because innovation requires a tolerance for risk and change individualism seems to be important perhaps because of its association with autonomy independence and freedom lack of power distance appears important perhaps reflecting the role that tolerance of change in the social order and distribution of power play in the innovation process third the study indicates that the strength of the relationship between innovation and two cultural values individualism and lack of power distance were stronger in 1975 than in 1980 suggesting perhaps that these values are becoming less important in spurring the innovation process this finding supports the anecdotal evidence that many collectivist and hierarchical asian nations are becoming more innovative fourth this study shows that per capita income is a more important economic variable than industrial structure in determining national rates of innovation this finding confirms previous work that has shown that as nations become wealthier they become more innovative the reason may be that wealthier countries have more demand for innovations both because innovations are often laborsaving and because wealthier nations have greater demand for new and differentiated consumer goods

a retrospective on mnc knowledge transfer subsidiary absorptive capacity and hrm in this retrospective we revisit the goals of the original paper and we review the studies that have used our paper to discuss the concept and the development of absorptive capacity we also propose directions for future research stressing the need to develop thorough theoretical and empirical models of absorptive capacity as a multi level and dynamic construct that is contingent on the context in which it is embedded

search in asset markets market structure liquidity and welfare this paper investigates how market structure affects efficiency and several dimensions of liquidity in an asset market to this end we generalize the search theoretic model of financial intermediation of darrell duffie et al 2005 to allow for entry of dealers and unrestricted asset holdings

the cooperative venture formation process a latent variable structural modeling approach this article addresses management process issues for forming cooperative ventures with an increased likelihood of subsequent success based on roos 1989 the cooperative venture formation process is conceptualized in terms of three theoretical constructs the extent of sufficient internal push for the project the breadth and depth of analytical scope and the strength of key stakeholder support these constructs are related to subsequent perceived performance data from sixty seven firms were collected and analyzed via latent variable structural modeling a partial least square pls one key contribution of this article is the modeling approach to strategic formation process it contributes to an existing but not very well developed theory regarding strategy formation processes the pls method used in this study is quite unique within strategy research as such it contributes to methodology development in the strategy research field the main managerial implication is that the process by which a cooperative venture is formed should largely be seen as a step by step approach not a discrete decision if the three fundamentals discussed in the article are thoroughly addressed we can up the ante for success during implementation and therefore subsequent performance

knowledge acquisition from foreign parents in international joint ventures an empirical examination in the hungarian context in this paper we examine organizational characteristics structural mechanisms and contextual factors that influence knowledge acquisition from the foreign parent in international joint ventures ijvs we in turn relate assessments of knowledge acquisition to ijv performance the data come from a survey of ijvs in the hungarian context where learning and knowledge acquisition from the foreign parent is thought to be particularly critical adaptation mechanisms such as capacity to learn articulated goals and structural mechanisms such as the provision of training technology and managerial assistance by foreign parents all were positively associated with the degree to which ijvs reported acquiring knowledge from their foreign parents we also found limited support for the belief that cultural conflicts can impede knowledge acquisition but only for two party joint ventures with 50 50 equity arrangements we also looked at the relationship between knowledge acquisition and different dimensions for evaluating ijv performance the relationship between knowledge acquisition and performance was significant for all indicators of performance through knowledge acquisition from the foreign parent and the organizational characteristics hypothesized to enhance ijv knowledge acquisition affected assessments of some dimensions of performance more than others our findings contribute to advancing knowledge about the relationship between organizational characteristics and organizational knowledge acquisition in ijvs as well as the relationships between knowledge acquisition and different dimensions of ijv performance

on the existence of lindahl hotelling equilibria abstract we consider an economy characterized by the simultaneous presence of public goods and many increasing returns to scale firms we formalize a notion of equilibrium termed a lindahl hotelling equilibrium in which producer prices are marginal cost prices and the public goods are financed through lindahl prices sufficient conditions are provided for such an equilibrium to exist

microfoundations in international management research the case of knowledge sharing in multinational corporations microfoundations have become an important theme in recent macro management research however the international management im field is an exception to this we document the lack of attention on microfoundations in im research by focusing on knowledge sharing a key im research field which we investigate by means of a keyword based literature study of the leading im and general management journals we discuss possible reasons why microfoundations have so far met with less resonance in im research we point to the training and background of im scholars as possible reasons we also highlight the significance that im scholars place on context and structure in explanation these may be seen as contrary to a microfoundations perspective a view that we show is incorrect we end by identifying several microfoundational issues in im research calling for a sustained effort with respect to theory heuristics and empirics

a theory of the firm with non binding employment contracts this paper examines an employment relation in which individual workers enjoy some bargaining power vis a vis the firm although they are not unionized the main elements of the situations studied here are that the employment contracts are non binding across periods of production and that the firm has opportunities to replace workers the paper analyzes a dynamic model in which the processes of contracting and recontracting between the firm and its workers are intertwined with the dynamic evolution of the firm s workforce the analysis of the model is somewhat complicated because the employment level is a nondegenerate state variable that evolves over time and is affected by past decisions the main analytical results characterize certain important equilibria the profit maximizing and stationa ry equilibria the unique stationary equilibrium is markedly inefficient it exhibits inefficient over employment and the steady state wages coincide with the workers reservation wage it confirms earlier results derived by stole and zwiebel 1996a b in the context of a static model and shows that they are very robust even when the firm has nearly frictionless hiring opportunities in contrast in the profit maximizing equilibrium the outcome is nearly efficient and the wage exhibits a mark up over the reservation wage

liquidity a new monetarist perspective this essay surveys the new monetarist approach to liquidity work in this literature strives for empirical and policy relevance plus rigorous foundations questions include what is liquidity is money essential in achieving desirable outcomes which objects can or should serve in this capacity when can asset prices differ from fundamentals what are the functions of commitment and collateral in credit markets how does money interact with credit and intermediation what can and should monetary policy do the research summarized emphasizes the micro structure of frictional transactions and studies how institutions like monetary exchange credit arrangements or intermediation facilitate the exchange process

the existence of marginal cost pricing equilibria with increasing returns the competitive mechanism fails in economies with nonconvex technologies competitive equilibria do not exist in general and pareto optima are no longer equilibria the search for alternative mechanisms in economies with increasing returns was developed and resulted in the principle of marginal cost pricing modern economic theory has returned to the foundations of marginal cost pricing theory in a general equilibrium framework the existence of equilibria with marginal cost pricing in economies with increasing returns and a more general type of nonconvexities is analyzed in this paper the case of differentiable economies where all production sets are limited by smooth surfaces is developed the principles of the proof are also extended to the nondifferentiable case

public economics yesterday today and tomorrow public economics that is to say the study of public intervention in the economy 1 has emerged from public finance in the 1950s to reach its autonomy at the beginning of the seventies with in particular the creation of the journal of public economics in 1971 with some oversimplifications we are going to argue that modern public economics was born from taking into account more or less explicitly the informational constraints of the state in its role of production allocation and distribution of resources the criticism of the benevolent state by the virginia polytechnic institute and chicago schools followed today by a renewal of political economy constitutes the second major key to read the new developments of public economics this leads us to a presentation in four parts section 2 will overview the implications of the arrow debreu general equilibrium paradigm in public economics section 3 will present some essential results obtained in public economics when the informational constraints of the state are taken into account the paradigm of the benevolent state will be criticized in section 4 section 5 will briefly sketch our view of the immediate future for public economics

existence of marginal cost pricing equilibria the nonsmooth case in this article we report a general existence theorem of a marginal cost pricing equilibrium for an economy which may exhibit increasing returns to scale or more general types of nonconvexities in the production sector our model considers an arbitrary number of firms and no smoothness assumption is made on their production sets or on the aggregate production set in this article we report a general existence theorem of marginal cost pricing equilibria for an economy which may exhibit increasing returns to scale or more general types of nonconvexities in the production sector in our model which considers a positive finite numbers 1 of commodities m of consumers and n of firms a consumers maximize their preferences subject to their budget constraints b convex producers maximize profits while nonconvex producers are instructed to follow the marginal pricing rule i e they fulfill the first order necessary condition for profit maximization in a precise mathematical sense formalized with clarke s normal cone our treatment of convex and nonconvex producers will in fact be symmetric the technological possibilities of the jth producer j 1 n

cultural differences and capability transfer in cross border acquisitions the mediating roles of capability complementarity absorptive capacity and social integration this paper presents an integrative model of the impact of cultural differences on capability transfer in cross border acquisitions we propose that cultural differences affect the post acquisition capability transfer through their impact on social integration potential absorptive capacity and capability complementarity two dynamic variables the use of social integration mechanisms and the degree of operational integration of the acquired unit are proposed to moderate the effects of cultural differences on social integration and potential absorptive capacity the implications for acquisition research and practice are discussed

the effects of corporate restructuring on aggregate industry specialization it has been widely argued that the purpose of corporate restructuring during the 1980s was to produce a population of more industry specialized competitive firms in response to intensifying global competition a number of studies show that corporate restructuring resulted in increased corporate focus during the 1980s however no study has yet examined whether corporate restructuring resulted in increased specialization at the industry level during the 1980s this study examines this issue first we examine whether or not aggregate industry specialization increased during the 1980s that is we ask did the average firm in any given u s industry become more or less specialized to that industry during the 1980s second we examine whether corporate restructuring was a significant determinant of change in aggregate industry specialization during the 1980s using a sample of 686 four digit sic industries and 64 two digit industry groups this study finds that aggregate industry specialization declined very slightly at both the four digit and two digit level between 1981 and 1989 this study also finds that sell offs of establishments through corporate control transactions or interfirm asset sales had no significant effect on aggregate industry specialization

on a general existence theorem for marginal cost pricing equilibria abstract we report a generalization of recent results on the existence of marginal cost pricing equilibria mcpe in economies with an increasing returns to scale industry our result makes no ad hoc assumptions which force the equilibrium to be on the efficiency frontier of the aggregate production possibility set we also present an additional condition under which our mcpe are productively efficient in the aggregate
