time orientation and asset prices we analyze a general equilibrium asset pricing model where a small subset of the consumers investors have a short run urge to save that is their attitude toward consumption in the long run is a standard one f they do place zero weight on consumption far enough out in the future f but their short run effective rates of discount may be negative our model which is an elaboration on the framework proposed by faruk gul and wolfgang pesendorfer does not feature time inconsistencies thus we view consumers as fully rational but subject to specific internal frictions in the form of temptation and self control problems the model nests the mehra prescott model and we use it as a way of interpreting the wealth and asset pricing data some aspects of these data we argue can possibly be better understood using our model than the standard one r 2002 published by elsevier science b v

temptation and social security in a dynastic framework abstract we investigate welfare and aggregate implications of a pay as you go payg social security system in a dynastic framework in which individuals have self control problems the presence of self control problems induces individuals to save less because of their urge for temptation towards current consumption individuals efforts to balance between the short term urge for temptation and the long term commitment for consumption smoothing result in self control costs in this environment payg social security works as a self control cost reducing device in contrast the presence of altruism induces individuals to save more this in turn mitigates the adverse effects of self control problems and payg social security on savings but magnifies the self control costs we find that in our environment the adverse welfare effects of a payg system are further mitigated relative to the environments that incorporate altruism and self control issues separately however the level of mitigation is quite modest

wealth accumulation over the life cycle and precautionary savings this article constructs and simulates a life cycle model of wealth accumulation and estimates the parameters of the utility function the rate of time preference and the coefficient of risk aversion by matching the simulated median wealth profiles with those observed in the panel study of income dynamics and in the survey of consumer finances the estimates imply a low degree of patience and a high degree of risk aversion the results are used to study the importance of precautionary savings in explaining wealth accumulation they imply that wealth accumulation is driven mostly by precautionary motives at the beginning of the life cycle whereas savings for retirement purposes become significant only closer to retirement

global value chain governance a relational perspective global value chain gvc governance is an established field within international business research yet the relational aspects of gvcs have to date garnered less scholarly attention than have efficiency considerations this conceptual study s objective is to explore the relational dynamics of gvc governance using an internalization theory perspective and by linking gvc research with insights from the business network literature gvcs are argued to be a distinct form of asymmetrical networks associated with economizing and capability creation features as well as costs the orchestrating firm can thus enhance efficiency outcomes of the gvc using social mechanisms similar to those adopted by core actors in a business network in the study six such mechanisms were identified 1 selectivity 2 inclusion of non business intermediaries 3 joint strategizing 4 relational capital 5 multilateral feedback and 6 rules for equitable value distribution while safeguarding the gvc s efficiency the above social mechanisms are associated with challenges and limitations and therefore do not guarantee international competitive success however deployed in an integrative fashion these social mechanisms facilitate coordination thus economizing on bounded rationality reduce the hazards of imperfect effort by partners thus economizing on bounded reliability and foster innovation and new capability development

overcoming the liability of outsidership for emerging market mnes a capability building perspective this paper develops and discusses a model describing how multinational enterprises from emerging economies emnes overcome the liability of outsidership in their internationalization from a capability building perspective our aim is to celebrate the important intellectual contribution of johanson and vahlne j int bus stud 40 9 1411 1431 2009 who introduced the liability of outsidership concept we first discuss learning from the local environment that can reduce outsidership and then explain how greater absorptive capacity can translate into better performance internationally finally we elaborate on how the institutional environment further conditions the process and the outcomes of learning we conclude with some suggestions for future research from five theoretical perspectives learning social network theory institutional theory resource dependence theory and mne structure and design

liabilities of regional foreignness and the use of firm level versus country level data a response to dunning et al 2007 we are pleased that dunning et al have provided macro country level data demonstrating the increased internationalization of many nations over the past decade we also appreciate their findings lending support to our perspective on the regional nature of world business our work was based solely on micro firm level data both country level data and firm level data have methodological problems which we attempt to reconcile in this commentary we also address the broader conceptual issues of how to interpret country level vs firm level data

the nature of precautionary wealth abstract this paper uses the panel study of income dynamics to provide some of the first direct evidence that wealth is systematically higher for consumers with predictably greater income uncertainty however the apparent pattern of precautionary wealth is not consistent with a standard parameterization of the life cucle model in which consumers are patient enough to begin saving for retirement early in life wealth is estimated to be far less sensitive to uncertainty than implied by that model instead our results suggest that over most of their working life time consumers behave in accordance with the buffer stock models of saving described in carroll 1992 1997 or deaton 1991 in which consumers hold wealth principally to insulate consumption against near term fluctuations in income

buffer stock saving in retirement accounts abstract we use a dynamic programming model to explore the possibility and extent of precautionary saving in tax sheltered accounts such as the 401 k the main policy experiment examines the behavior of saving for different levels of unemployment insurance ui which is a perfect substitute for precautionary saving against job loss our results indicate that increasing the generosity of ui crowds out 401 k contributions made by younger workers who save primarily for precautionary reasons at the aggregate level we find that 401 k s increase national saving and that the magnitude of the effect depends on the generosity of ui

a perspective on regional and global strategies of multinational enterprises multinational enterprises mnes are the key drivers of globalization as they foster increased economic interdependence among national markets the ultimate test to assess whether these mnes are global themselves is their actual penetration level of markets across the globe especially in the broad triad markets of nafta the european union and asia yet data on the activities of the 500 largest mnes reveal that very few are successful globally for 320 of the 380 firms for which geographic sales data are available an average of 80 3 of total sales are in their home region of the triad this means that many of the world s largest firms are not global but regionally based in terms of breadth and depth of market coverage globalization in terms of a balanced geographic distribution of sales across the triad thus reflects a special and rather unusual outcome of doing international business ib the regional concentration of sales has important implications for various strands of mainstream ib research as well as for the broader managerial debate on the design of optimal strategies and governance structures for mnes journal of international business studies 2004 35 3 18 doi 10 1057 palgrave jibs 8400073

multidivisional vs metanational governance of the multinational enterprise the effective and efficient management of diversified business firms that supply multiple products and operate in multiple dynamic markets especially large multinational enterprises mnes builds upon a number of specific governance principles these governance principles allow the alignment of environmental characteristics strategy and organization given the rising need to learn from the world doz et al in their influential harvard business school press book entitled from global to metanational have proposed a new set of governance principles described under the metanational umbrella concept this paper revisits the metanational using a comparative institutional perspective here we contrast multidivisional and metanational governance principles a comparative institutional analysis suggests that the metanational s application potential in terms of actually improving the effectiveness and efficiency of mne governance may be subject to more qualification than suggested by doz et al senior mne management must therefore reflect carefully before substituting metanational governance principles for the more conventional multidivisional ones with established contributions to managerial effectiveness and efficiency

the role of intergenerational transfers and life cycle saving in the accumulation of wealth he purpose of this paper is to review what economists know at present about the following question how large a portion of the existing wealth is the result of a bequest motive that is of accumulation for the specific purpose of leaving bequests i will also endeavor to clarify why an answer to this question is of interest in the early keynesian period when the study of national saving first attracted wide interest relatively little attention was paid to what led people to save though it was generally understood that the main systematic reason was to leave bequests j m keynes in the famous chapter 9 of the general theory of employment interest and money 1936 had listed seven distinct motives for saving besides the leaving of bequests but five of these which include to increase one s future income or to insure one s independence and power implied that all or nearly all the accumulation would finally wind up as bequeathed wealth this in turn meant that most private wealth originated through bequests that is it either had been received through bequests or was destined to be bequeathed and indeed how else could society accumulate wealth however keynes 1936 p 107 also mentioned two further motives precaution that is to build up a reserve against unforeseen contingencies and foresight that is to provide for an anticipated future relation between the income and the needs of the individual or his family different from that which exists in the present as for example in relation to old age family education or the maintenance of dependents these motives in contrast to most of the previous ones have the

temptation and self control some evidence and applications this paper studies the empirical relevance of temptation and self control using household level data from the consumer expenditure survey we construct an infinite horizon consumption savings model that allows but does not require temptation and self control in preferences in the presence of temptation a wealth consumption ratio in addition to consumption growth becomes a determinant of the asset pricing kernel and the importance of this additional pricing factor depends on the strength of temptation to identify the presence of temptation we exploit an implication of the theory that a more tempted individual should be more likely to hold commitment assets such as individual retirement account ira or 401 k accounts our estimation provides empirical support for temptation preferences based on our estimates we explore some quantitative implications of this class of preferences for capital accumulation in a neoclassical growth model and the welfare cost of the business cycle

offshoring administrative and technical work new fields for understanding the global enterprise in this paper we introduce the journal of international business studies special issue on offshoring administrative and technical services ats in doing so we have attempted to locate the topic within the international business research tradition as well as suggest challenges and opportunities that the phenomenon offers to theoretical and empirical research in the field we examine the interplay of costs knowledge and innovation in the evolution of ats offshoring from modest beginnings to its current stature as an accepted business practice we suggest that understanding the continuing evolution of ats offshoring requires researchers to take into account not only the business imperative of cost saving but also a more complex set of underlying factors and potential outcomes we argue that the rapid growth of ats offshoring has brought about an accumulation of resources including financial flows knowledge infrastructure and human capital to create new platforms for knowledge creation and innovation low costs may characterize the initial conditions for offshoring but they also provide the basis for up market moves as firms increasingly pursue innovation based strategies we introduce the papers in the special issue as integral elements in our discussion contributing new ideas that stimulated our thinking and hopefully will do the same for others seeking to understand this emerging area of globalization and international managerial practice journal of international business studies 2009 40 887 900 doi 10 1057 jibs 2009 22

saving and liquidity constraints this paper is concerned with the theory of saving when consumers are not permitted to borrow and with the ability of such a theory to account for some of the stylized facts of saving behavior the models presented in the paper seem to account for important aspects of reality that are not explained by traditional life cycle models copyright 1991 by the econometric society

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

social security and self control preferences abstract we analyze the welfare effects of an unfunded social security system we do so using an overlapping generations economy wherein agents have self control preferences face mortality risk individual income risk and borrowing constraints given our specification of preferences unfunded social security helps reduce the agents temptation to consume in every period consequently the welfare costs it otherwise entails are substantially mitigated while both social security and self control when considered separately reduce welfare their combination renders this effect considerably less severe moreover if the cost of resisting temptation is very high the introduction of social security might even improve welfare

an evolutionary approach to understanding international business activity the co evolution of mnes and the institutional environment this paper examines the co evolution of mne activities and institutions external and internal to the firm we develop a theoretical framework for this analysis that draws on the more recent writings of douglass north on institutions as a response to complex forms of uncertainty associated with the rise in global economic interconnectedness and of richard nelson on the co evolution of technology and institutions we link historical changes in the character of mne activities to changes in the institutional environment and highlight the scope for firm level creativity and institutional entrepreneurship that may lead to co evolution with the environment we argue that the main drivers for institutional entrepreneurship are now found in the increasing autonomy of mne subsidiaries thus mne agency derives from more decentralized forms of experimentation in international corporate networks which competence creating nodes of new initiatives can co evolve with local institutions unlike most other streams of related literature our approach connects patterns of institutional change in wider business systems with more micro processes of variety generation and experimentation within and across individual firms this form of co evolutionary analysis is increasingly important to understanding the interrelationships between mne activities and public policy

measuring self control problems we develop a survey instrument to measure self control problems in a sample of highly educated adults this measure relates in the manner that theory predicts to liquid wealth accumulation and personality measures yet while self control problems are typically seen as resulting in overconsumption and low wealth we identify a significant group who underconsume and thereby accumulate high levels of wealth in addition self control problems are smaller in scale for older than for younger respondents those who put money aside in retirement accounts may be delaying access to a point at which self control problems are no longer important jel d12 d14

are americans saving optimally for retirement we solve each household s optimal saving decisions using a life cycle model that incorporates uncertain lifetimes uninsurable earnings and medical expenses progressive taxation government transfers and pension and social security benefits with optimal decision rules we compare household by household wealth predictions from the life cycle model using a nationally representative sample we find making use of household specific earnings histories that the model accounts for more than 80 percent of the 1992 cross sectional variation in wealth fewer than 20 percent of households have less wealth than their optimal targets and the wealth deficit of those who are undersaving is generally small

extending the theory of the multinational enterprise internalization and strategic management perspectives this paper assesses the continued relevance of buckley and casson s 1976 book on the future of the multinational enterprise mne against a background of increasing criticism of transaction cost related scholarly work we demonstrate that the schism that can currently be observed in the field between international business and international management is misguided as the transaction cost internalization school may offer useful insights to both management scholars and managers for this to occur however it is necessary first to extend the empirical scope of transaction cost based reasoning to include the functioning of differentiated network mnes the paper suggests that buckley and casson s book still represents a beacon of clarity and a superb starting point for the study of the mne even if the complexity of this governance structure has grown far beyond what any international business scholar or even international management scholar could have predicted 25 years ago

measuring self control problems a structural estimation we perform a structural estimation of the preference parameters in a buffer stock consumption model augmented with temptation disutility we adopt a two stage method of simulated moments methodology to match our simulated moments with those observed in the us survey of consumer finances to identify the parameters we use liquid and quasi liquid retirement wealth holdings at different ages as target moments we find evidence of a significantly positive degree of temptation and estimates under the unrestricted model are more precise than estimates under the restricted model with no temptation overall a model with temptation preferences explains better the observed target moments

the entrepreneurial m form strategic integration in global media firms many researchers believe that bounded rationality prevents ceos in large complex multidivisional m form corporations from personally formulating division level strategies instead ceos are seen as guiding a bottom up process whereby division managers propose strategies for review and approval by the corporate office contrary to this view we argue that ceos in global media firms frequently drive strategy in a top down manner especially when their firms seek to expand by integrating the activities of two or more existing divisions we refer to such firms as entrepreneurial m forms and maintain that their reliance on an activist ceo offers benefits 1 in turbulent environments when the use of slow bottom up planning processes risks forfeiting first mover advantages and 2 when expansion entails major capital commitments and division managers may be reluctant to accept the career risks associated with sponsorship of bet the company projects

social security reform with self control preferences abstract this paper analyzes a fully funded social security system under the assumption that agents face temptation issues agents are required to save through individually managed personal security accounts without and with mandatory annuitization when the analysis is restricted to crra preferences our results are congruent with the literature in indicating that the complete elimination of social security is among the reform scenarios that maximize welfare however when self control preferences are introduced and as the intensity of self control becomes progressively more severe the social security elimination scenario loses ground very rapidly in fact in the case of relatively severe temptation the elimination of social security becomes the least desirable alternative under the light of the above findings any reform proposal regarding the social security system should consider departures from standard preferences to preference specifications suitable for dealing with preference reversals

corporate venture capitalists autonomy obstacles and performance abstract this report presents the results of a formal study of the corporate venture capital community in the united states and is based upon responses to a questionnaire completed by 52 corporate venture capitalists cvcs the central question addressed in this study involves which approach to corporate venture capital is most likely to produce successful results this question was addressed via cluster analysis which segregated the cvc community into two broad classes pilots which are marked by substantial organizational independence and copilots which are highly dependent on corporate management with respect to venture funding and decision authority pilots achieve equal or higher levels of performance and are plagued by far fewer obstacles than their highly dependent counterparts the results suggest the following 1 the corporate venture fund should be established as an independent entity and should have access to a committed separate pool of funds this will enable cvcs to respond aggressively to and manage investment opportunities with minimal corporate interference such an independent entity will defuse justifiable concerns on the part of entrepreneurs related to such interference 2 the fund should be managed by skilled venture professionals who may be drawn from the independent venture community or the small but growing pool of experienced cvcs corporate executives may comprise a part of the management team 3 if the corporate venture fund hopes to attract top quality managers it must be prepared to offer compensation and authority commensurate with their skill level in short corporate venture capitalists should be treated like independent venture capitalists by organizing the fund as an independent entity the political problem associated with establishing compensation levels above those of the corporation can be minimized 4 all cvcs should establish a primary focus on the realization of financial objectives i e return on investment strategic benefit objectives are not necessarily ill advised so long as they do not interfere with sound financial decision making when they do the corporate venture capital process is likely to become less effective for instance a corporate venture fund should only confine itself to investing in a few industries if there are sufficient high grade investment opportunities within those industries to ensure adequate deal flow the venture fund should not be pressured investments that appear exciting from a corporate perspective for technological or marketing reasons but are not financially attractive may well drain resources rather than produce opportunities 5 venture proposals failing on financial criteria might be referred to other parts of the corporation with the purpose of exploring an alternate relationship e g a development contract or joint venture if this is appealing to the corporation a mechanism such as a corporate liaison or reporting system might be established to facilitate the flow of information 6 a corporation should be willing to make a complete commitment of talent and capital if it establishes its own corporate venture fund the corporation should then be willing to accept a limited role if the corporation is unable to accept a limited role with respect to its own fund it may be best for it to participate as an investor in a traditional fund where such limitations will be enforced however this latter approach may significantly dilute or eliminate potential for strategic benefits

the fable of fisher body abstract general motors s gm s acquisition of fisher body is the classic example of market failure in the literature on contracts and the theory of the firm according to the standard account in 1926 gm merged vertically with fisher body a maker of auto bodies because of concerns over transaction specific investment and contractual holdup that account exhibits errors of historical fact and interpretation general motors acquired a 60 percent interest in fisher body in 1919 moreover the contractual arrangements and working relationship prior to the 1926 merger exhibited trust rather than opportunism fisher body s production technology did not exhibit asset specificity the merger reflected economic considerations specific to that time not some immutable market failure we demonstrate that vertical integration was directed at improving coordination of production and inventories assuring gm of adequate supplies of auto bodies and providing gm with access to the executive talents of the fisher bro

self control and the theory of consumption to study the behavior of agents who are susceptible to temptation in infinite horizon consumption problems under uncertainty we define and characterize dynamic self control dsc preferences dsc preferences are recursive and separable in economies with dsc agents equilibria exist but may be inefficient in such equilibria steady state consumption is independent of initial endowments and increases in self control increasing the preference for commitment while keeping self control constant increases the equity premium removing nonbinding constraints changes equilibrium allocations and prices debt contracts can be sustained even if the only feasible punishment for default is the termination of the contract

managerial governance adaptation in the multinational enterprise in honour of mira wilkins we propose an analytical business history approach informed by new internalisation theory to study managerial governance adaptation in the multinational enterprise mne we shed new light on the timing and the scale of managerial governance adaptation these two issues have remained largely unaddressed in mainstream international business theory we uncover the importance of delayed larger scale governance adaptation as a response to cumulative localised commitment failures we illustrate our new perspective on managerial governance adaptation by providing a short retrospective of wilkins and hill s american business abroad ford on six continents cambridge university press cambridge 1964 classic historical account of ford motor company s expansion across six continents between 1903 and 1963 our brief retrospective highlights the value of in depth historical analysis informed by umbrella behavioural assumptions such as those adopted in new internalisation theory based research to gain improved understanding of international strategy and governance trajectories of large mnes

tying odysseus to the mast evidence from a commitment savings product in the philippines we designed a commitment savings product for a philippine bank and implemented it using a randomized control methodology the savings product was intended for individuals who want to commit now to restrict access to their savings and who were sophisticated enough to engage in such a mechanism we conducted a baseline survey on 1777 existing or former clients of a bank one month later we offered the commitment product to a randomly chosen subset of 710 clients 202 28 4 percent accepted the offer and opened the account in the baseline survey we asked hypothetical time discounting questions women who exhibited a lower discount rate for future relative to current trade offs and hence potentially have a preference for commitment were indeed significantly more likely to open the commitment savings account after twelve months average savings balances increased by 81 percentage points for those clients assigned to the treatment group relative to those assigned to the control group we conclude that the savings response represents a lasting change in savings and not merely a short term response to a new product

the end of the opportunism vs trust debate bounded reliability as a new envelope concept in research on mne governance modern transaction cost economics tce thinking has developed into a key intellectual foundation of international business ib research but the williamsonian version has faced substantial criticism for adopting the behavioral assumption of opportunism in this paper we assess both the opportunism concept and existing alternatives such as trust within the context of ib research especially work on multinational enterprise mne governance case analyses of nine global mnes illustrate an alternative to the opportunism assumption that captures more fully the mechanisms underlying failed commitments inside the mne as a substitute for the often criticized assumption of opportunism we propose the envelope concept of bounded reliability brel an assumption that represents more accurately and more completely the reasons for failed commitments without invalidating the other critical assumption in conventional tce and internalization theory thinking namely the widely accepted envelope concept of bounded rationality brat bounded reliability as an envelope concept includes two main components within the context of global mne management opportunism as intentional deceit and benevolent preference reversal the implications for ib research of adopting the bounded reliability concept are far reaching as this concept may increase the legitimacy of comparative institutional analysis in the social sciences

temptation driven behavior and taxation a quantitative analysis in a life cycle model i introduction a central research question in the dynamic fiscal policy literature during the last 30 years or so is whether under fairly general modeling choices the government should impose a positive tax on capital income in the long run the original answer to this question is negative and is due to the seminal papers by chamley 1986 and judd 1985 who established that in the context of a standard neoclassical growth model with infinitely lived individuals an optimal income tax policy entails taxing capital at confiscatory rates in the short run and setting capital income taxes equal to zero in the long run only labor income should be taxed in the long run since then several modeling choices that cast doubt on the validity of this result were identified in the literature imrohoroglu 1998 showed that the optimal capital income tax rate is strictly positive in an overlapping generations olg setting where individuals face idiosyncratic earnings risk borrowing constraints and life span uncertainty conesa kitao and krueger 2009 extended imrohoroglu 1998 by adding a labor leisure choice they demonstrated that the optimal capital income tax rate is equal to 36 and concluded that this high rate is mainly driven by the life cycle structure of the model in contrast krusell kuruscu and smith 2010 analytically showed that within a class of ramsey tax schemes the optimal capital income tax rate should be negative that is savings should be subsidized when agents have self control problems moreover in the special case where consumers succumb completely to temptation ramsey taxes deliver first best welfare outcomes and in contrast to the chamley judd result the optimum calls for a subsidy to savings however an integrated assessment of the combined effects of the relevant trade offs both along the dimension of differences in preferences and along the dimension of the scope of capital income taxation versus labor income taxation is missing from all previous studies in both social security and capital taxation literature and this paper aims to bridge the gap in the literature and contribute in this aspect to the best of our knowledge this paper is the first study that introduces temptation driven preferences in a quantitative model aiming to tackle the question on the optimal capital income tax before proceeding to specifically articulate this paper s contribution to the literature we consider critical to address a question that lies at the very core of our line of research namely why fiscal policy models with time inconsistent or self control preferences are relevant in the first place initially the literature pioneered by strotz 1956 and phelps and poliak 1968 corroborated evidence coming from both introspection and experiments that agents exhibit preference reversals as time passes different strands within this literature have suggested that these preference reversals could be induced by either time inconsistent preferences see laibson 1997 or self control preferences gul and pesendorfer 2004 time inconsistent preferences typically assume that agents have sequences of different selves each valuing consumption streams in a unique way in contrast gul and pesendorfer 2004 provide a dynamically consistent model suitable for addressing preference reversals that does not necessitate splitting up the consumer in multiple selves that is self control preferences these preferences describe an individual that in every period is tempted to consume his entire endowment when he consumes less than his endowment he incurs a disutility cost that stems from exercising self control that is self control cost optimal behavior trades off the temptation to consume vis a vis the long run self interest of the individual 1 alongside these theoretical underpinnings there is sound empirical and experimental evidence that agents suffer from self control problems
