technological specialization and the decline of diversified firms we document a strong decline in corporate diversification activity since the late 1970s and we develop a dynamic model that explains this pattern both qualitatively and quantitatively the key feature of the model is that synergies endogenously decline with technological specialization leading to fewer diversified firms in equilibrium the model further predicts that segments inside a conglomerate should become more related over time which is consistent with the data finally the calibrated model also matches other empirical magnitudes well output growth rate market to book ratios diversification discount frequency and returns of diversifying mergers and frequency of refocusing activity

financial intermediary coalitions abstract in this article an environment in which the investment opportunities of agents are private information is studied and it is shown that financial intermediaries arise endogenously within that environment it is established that financial intermediaries are part of an efficient arrangement in the sense that they are needed to support the authors private information core allocations these intermediaries which are coalitions of agents exhibit the following characteristics in equilibrium they borrow from and lend to large groups of agents they produce information about investment projects and they issue claims that have different state contingent payoffs than claims issued by ultimate borrowers

child labour use and economic growth an econometric analysis we present a simple dynamic theory of child labour human capital formation and economic growth that is consistent with some of the main features of child labour and economic development the model supports a number of testable hypotheses which we investigate econometrically in a systems approach using panel data from 64 countries in the period 1960 1980 the econometric results match the theory well the incidence of child labour is negatively related to parental human capital and education quality but is positively correlated with education cost further countries with higher amounts of child labour tend to have lower stocks of human capital in the future there is also a convergence phenomenon between the level and growth of human capital the lower the current stock of human capital the higher is current child labour use and the faster is the growth rate of human capital

internal capital markets and the competition for corporate resources this article examines the role of corporate headquarters in allocating scarce resources to competing projects in an internal capital market unlike a bank headquarters has control rights that enable it to engage in winner picking the practice of actively shifting funds from one project to another by doing a good job in the winner picking dimension headquarters can create value even when it cannot help at all to relax overall firm wide credit constraints the model implies that internal capital markets may sometimes function more efficiently when headquarters oversees a small and focused set of projects this article analyzes the process by which internal capital markets channel limited resources to different uses inside a company in so doing it seeks to address two related sets of questions first what is the fundamental economic rationale for creating an internal capital market that is under what circumstances can it make sense to combine several technologically distinct projects under one roof and have them seek funding from corporate headquarters as opposed to setting them up as stand alone companies that each raise external financing on their own second given this rationale what is the optimal size and scope of an internal capital market should headquarters be involved in funding a large number of projects or just a few and should these projects be unrelated to one another or in similar lines of business the answers to both sets of questions flow from the insight that in a credit constrained setting where not all positive npv projects can be financed headquarters can create value by actively reallocating scarce funds across projects for example the cash flow generated by one division s activities may be taken and spent on investment in another division where the returns are higher or alternatively one division s assets may be used as collateral to raise financing that is then diverted to the other division simply put individual projects must compete for the scarce funds and headquarters job is to pick the winners and losers in this competition

public versus private investment in human capital endogenous growth and income inequality in this paper we present an overlapping generations model with heterogeneous agents in which human capital investment through formal schooling is the engine of growth we use simple functional forms for preferences technologies and income distribution to highlight the distinction between economies with public education and those with private education we find that income inequality declines more quickly under public education on the other hand private education yields greater per capita incomes unless the initial income inequality is sufficiently high we also find that societies will choose public education if a majority of agents have incomes below average

revisiting the bright and dark sides of capital flows in business groups prior studies report that the business group structure and the associated intra group capital flows are prone to conflicts of interest between controlling shareholders and minority investors yet business group is a prevalent and stable structure around the globe particularly where capital markets are underdeveloped using data from china this paper empirically studies the trade off between the negative and positive roles played by intra group capital flows and tests the efficiency implications of such trade off we find that from the perspective of the whole group intra group capital flows are most efficient when the groups are least subject to conflicts of interest between controlling shareholders and minority shareholders and when they face strong external financing constraints

the economics of child labor if child labor as a mass phenomenon occurs not because of parental selfishness but because of the parents concern for the household s survival the popular argument for banning child labor loses much of its force however this assumption about parental decision making coupled with the assumption of substitutability in production between child and adult labor could result in multiple equilibria in the labor market with one equilibrium where children work and another where adult wage is high and children do not work the paper establishes this result and discusses its policy implications copyright 1998 by american economic association

creditor rights and debt allocation within multinationals we analyze the optimal debt structure of multinational corporations choosing between centralized or decentralized borrowing we identify how this choice is affected by creditor rights and bankruptcy costs taking into account managerial incentives and coinsurance considerations we find that partially centralized borrowing structures are optimal with either weak or strong creditor rights for intermediate levels of creditor rights fully decentralized centralized borrowing structures are optimal if managers have strong weak empire building tendencies decentralized borrowing is more attractive for companies focussing on short term profitability credits are rather taken in countries with better creditor rights and more efficient insolvency systems

financing a portfolio of projects this article shows that investors financing a portfolio of projects may use the depth of their financial pockets to overcome entrepreneurial incentive problems competition for scarce informed capital at the refinancing stage strengthens investors bargaining positions and yet entrepreneurs incentives may be improved because projects funded by investors with shallow pockets must have not only a positive net present value at the refinancing stage but one that is higher than that of competing portfolio projects our article may help understand provisions used in venture capital finance that limit a fund s initial capital and make it difficult to add more capital once the initial venture capital fund is raised jel g24 g31 venture capital finance takes place in an environment of severe informational asymmetries and incentive problems venture capitalists not only must assess the quality of investment proposals submitted to them for funding but once the initial funding has taken place they must also give the right incentives to the entrepreneurs and monitor the performance of the portfolio companies on an ongoing basis this article departs from most of the existing literature by explicitly recognizing that venture capitalists manage a portfolio of projects the need for portfolio management arises if the amount of capital both financial and human available to a venture capital fund is limited implying that venture capitalists must carefully choose which projects to allocate their scarce financial and human resources to 1 by staging their investments venture capitalists retain the right to deny capital infusions to particular

is it inefficient investment that causes the diversification discount diversified conglomerates are valued less than matched portfolios of pure play firms recent studies find that this diversification discount results from conglomerates inefficient allocation of capital expenditures across divisions much of this work uses tobin s q as a proxy for investment opportunities therefore hypothesizing that q is a good proxy this paper treats measurement error in q using a measurement error consistent estimator on the sorts regressions in the literature i find no evidence of inefficient allocation of investment the results in the literature appear to be artifacts of measurement error and of the correlation between investment opportunities and liquidity diversif ied conglomerates appear to trade at a discount relative to matched portfolios of pure play firms studies documenting this stylized fact include lang and stulz 1994 berger and ofek 1995 comment and jarrell 1995 and servaes 1996 recent empirical work has sought to find the source of this diversification discount building on the theoretical work in milgrom and roberts 1990 stein 1997 and scharfstein and stein 2000 on the inefficiency of internal capital markets this literature has asked specifically whether diversified firms allocate their capital expenditures inefficiently across divisions the canonical answer has been yes and has been supported by two types of evidence first studies such as lamont 1997 shin and stulz 1998 shin and park 1998 and rajan servaes and zingales 2000 all find that internal capital markets in conglomerates transfer funds across divisions in a suboptimal manner second studies such as berger and ofek and scharfstein 1998 provide evidence suggesting that the divisions of conglomerates do not respond adequately to investment opportunities in comparison to single segment firms however these findings about divisional investment may be an artifact of measurement error most of these studies rely on tobin s q the market value of the capital stock divided by its replacement value as a proxy for investment opportunities and tobin s q is likely to be a poor proxy shin and stulz

south korean chaebols and value based management south korean industrial conglomerates chaebols are discussed in the context of value based management vbm recent economics and finance literature on the diversion of corporate resources from the firm to the controlling shareholders tunneling for which chaebols are notoriously known is discussed chaebols have engaged in empire building and expropriation of minority shareholders distorting the process of efficient resource allocation in south korea and became the root cause of the 1997 financial crisis we argue that the 1997 crisis should be viewed as a consequence of chaebols systematic deviation from the guiding principles of vbm we use tunneling within chaebols as an example of the need to directly address prohibition of the expropriation of minority shareholders as a primary postulate of vbm we argue that vbm should require that the value generated by the firm not be expropriated from minorities or any stakeholders by dominant shareholders we also examine moral and ethical considerations and present explanations as to why the unethical practice of tunneling has been tolerated by the south korean public we show that public opinion on tunneling is changing and that the treatment of minority shareholders by chaebols controlling families is becoming increasingly unacceptable to south koreans

the development of an infrastructure for entrepreneurship abstract this paper takes a macroperspective of entrepreneurship and focuses on the issues and events involved in constructing an industrial infrastructure that facilitates and constrains entrepreneurship this infrastructure includes 1 institutional arrangements to legitimate regulate and standardize a new technology 2 public resource endowments of basic scientific knowledge financing mechanisms and a pool of competent labor as well as 3 proprietary rd numerous entrepreneurial actors in the public and not for profit sectors play crucial roles it motivates one to examine the different roles played by these actors and how their joint contributions interact to develop and commercialize a new technology this in turn makes it possible to understand how the risk time and cost to an individual entrepreneur are significantly influenced by developments in the overall infrastructure for entrepreneurship it also explains why the entrepreneurs who run in packs will be more successful than those that go it alone to develop their innovations

child labor cause consequence and cure with remarks on international labor standards although the literature on child labor is enormous it lacks a common theoretical foundation in this paper analytical survey of this field is provided keeping in mind that this is an area where the primary reason for theorizing is ultimately to influence policy overall it is noted that the literature on child labor is an illustration of abundance and anarchy although empirical writings on child labor are numerous they are not usually founded on theory it is argued that there is much that can be done in curbing the issue of child labor several theories were studied in this paper including collaborative intervention such efforts include public action which alters the economic environment such that the parents of their own accord prefer to withdraw the child from labor force another strategy involves the government a legal intervention is enforcing a total ban on the subject although such interventions have good intentions some of them may not be feasible in general it is better to take economy wide measures against child labor and if there is to be a sector specific ban it should be based on the working conditions of that sector rather than the destination of the goods

is child labor inefficient we build a model of child labor and study its implications for welfare we assume that there is a trade off between child labor and the accumulation of human capital even if parents are altruistic and child labor is socially inefficient it may arise in equilibrium because parents fail to fully internalize its negative effects this occurs when bequests are zero or when capital markets are imperfect we also study the effects of a simple ban on child labor and derive conditions under which it may be pareto improving in general equilibrium we show that the implications of child labor for fertility are ambiguous

foreign banks and credit stability in central and eastern europe a panel data analysis abstract we examine whether foreign and domestic banks in central and eastern europe react differently to business cycles and banking crises our panel dataset comprises data of more than 250 banks for the period 1993 2000 with information on bank ownership and mode of entry during crisis periods domestic banks contracted their credit base whereas greenfield foreign banks did not also home country conditions matter for foreign bank growth as there is a significant negative relationship between home country economic growth and host country credit by greenfields finally greenfield foreign banks credit growth is influenced by the health of the parent bank

intertemporal capital budgeting abstract this paper analyzes the optimal capital budgeting mechanism when divisional managers are privately informed about the arrival of future investment projects consistent with field study evidence an optimal allocation mechanism can include a stipulation that a capital request for discretionary investment will be declined with positive probability in the period after a significant investment was made even though this is ex post suboptimal the model derives a number of empirical predictions regarding capital budgeting and the investment of financially constrained firms

teaching versus research a multi tasking approach to multi department universities we study the possible implications of incentive schemes as a tool to promote efficiency in the management of universities in this paper we show that by designing internal financial rules which create yardstick competition for research funds a multi department university may induce better teaching quality and research as compared to the performance of independent departments

tobin s q and the importance of focus in firm performance using tobin s q as a measure of performance we seek to estimate the relative importance of industry focus and share effects in determining firm performance our methods are analogous to those of richard schmalensee and like him we find that industry effects account for the majority of the explained variance however we also find that firm effects exist in the form of focus effects that is narrowly diversified firms do better than widely diversified firms we interpret this finding as consistent with profit maximization by firms with different factor endowments

financial intermediation and delegated monitoring this paper develops a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders it presents a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary diversification within an intermediary serves to reduce these costs even in a risk neutral economy the paper presents some more general analysis of the effect of diversification on resolving incentive problems in the environment assumed in the model debt contracts with costly bankruptcy are shown to be optimal the analysis has implications for the portfolio structure and capital structure of intermediaries

a theory of yardstick competition in the typical regulatory scheme a franchised monopoly has little incentive to reduce costs this article proposes a mechanism in which the price the regulatedfirm receives depends on the costs of identical firms in equilibrium each firm chooses a socially efficient level of cost reduction the mechanism generalizes to cover heterogeneous firms with observable differences medicare s prospective reimbursement of hospitals by using diagnostically related groups is a scheme very similar to the one outlined here

when does coordination require centralization this paper compares centralized and decentralized coordination when manag ers are privately informed and communicate strategically we consider a multi divisional organization in which decisions must be adapted to local conditions but also coordinated with each other information about local conditions is dispersed and held by self interested division managers who communicate via cheap talk the only available formal mechanism is the allocation of decision rights we show that a higher need for coordination improves horizontal com

the adaptive life cycle of entrepreneurial ecosystems the biotechnology cluster we propose an empirical framework for assessing the vibrancy and trajectory of regional entrepreneurial ecosystems we apply this framework to study the us national capital region s localized cluster of biotechnology related entrepreneurship by building our analysis around a set of indicators of ecosystem vitality proposed by stangler and bell masterson 2015 this application constitutes an initial attempt at mapping the dynamics of an industry cluster within the adaptive life cycle of a wider regional ecosystem we find that the biotechnology cluster in the national capital region entered a reorientation stage in the early 2000s building up stored energy capital and connectedness in non research oriented activities an increasing regional presence of large biotech firms in the past 5 years a highly active and diverse start up sector increasing merger and acquisition activity and declines in regional public funding for medical and clinical trials all suggest a transition of entrepreneurial activity in the region from a dynamic driven by federal research spillovers to one increasingly driven by private sector actors

reallocation of corporate resources and managerial incentives in internal capital markets abstract diversified firms often trade at a discount with respect to their focused counterparts the literature has tried to explain the apparent misallocation of resources with lobbying activities or power struggles we show that diversification can destroy value even when resources are efficiently allocated ex post when managers derive utility from the funds under their purview moving funds across divisions may diminish their incentives the ex ante reduction in managerial incentives can more than offset the increase in firm value due to the ex post efficient reallocation of funds this effect is robust to the introduction of monetary incentives moreover we show that asymmetries in size and growth prospects increase the diversification discount

the lineages of the entrepreneurial ecosystem approach in its most abstract sense an ecosystem is a biotic community encompassing its physical environment and all the interactions possible in the complex of living and nonliving components economics has always been about systems that explain differential output and outcomes however economics has generally ignored the role of entrepreneurship in economic systems just as entrepreneurship studies have largely overlooked the role of systems in explaining the prevalence and performance of entrepreneurship the entrepreneurial ecosystem approach has the promise to correct these shortcomings its two dominant lineages are the regional development literature and the strategy literature both lineages share common roots in ecological systems thinking providing fresh insights into the interdependence of actors in a particular community to create new value but studies of both regional development and strategic management have largely ignored the role of entrepreneurs in new value creation in this paper we will outline contributions to the entrepreneurial ecosystem approach and conclude with a promising new line of research to our understanding of the emergence growth and context of start ups that have achieved great impact by developing new platforms

the role of small firms in u s biotechnology clusters the biotechnology industry poses a particular challenge to analysis because its origins were poorly understood or even noticed at the time the purpose of this paper is to examine and make sense of recent developments in the u s biotechnology industry the pioneers and subsequent followers in biotechnology came from other fields they altered their career trajectories in sciences like genetics and medical research to enter an unknown and undefined field which only subsequently became labeled as biotechnology those regions exhibiting the greatest success in developing biotechnology clusters also possessed the greatest ability to unleash the potential commercialization latent in those scientists to generate a successful regional cluster the existence of world class scientific talent is a necessary condition however it is not a sufficient condition the ancillary or complementary factors must also be available to translate this knowledge into a commercialized product the complementary factors include the presence of venture capital and other forms of finance the existence of an entrepreneurial culture and transparent and minimal regulations fostering the start up and growth processes

managerial incentives and internal capital markets capital budgeting in multidivisional firms depends on the external assessment of the whole firm as well as on headquarters assessment of the divisions while corporate headquarters may create value by directly monitoring divisions the external assessment of the firm is a public good for division managers who consequently are tempted to free ride as the number of divisions increases the free rider problem is aggravated and internal capital markets substitute for external capital markets in the provision of managerial incentives the analysis relates the value of diversification to characteristics of the firm the industry and the capital market

the strategic impact of resource flexibility in business groups we show that in business groups with efficient internal capital markets resources may be channelled to either more or less profitable units depending on the amount of internal resources a group may exit a market in response to increased competition or channel funds to the subsidiary operating in that market this has important implications for the strategic impact of group membership affiliation to a monopolistic subsidiary can make a cash rich poor firm more less vulnerable to entry deterrence also resource flexibility within a group makes subsidiaries reaction functions flatter thus discouraging rivals strategic commitments when entry is accommodated

creating a cluster while building a firm entrepreneurs and the formation of industrial clusters feldman m p francis j and bercovitz j 2005 creating a cluster while building a firm entrepreneurs and the formation of industrial clusters regional studies39 129 141 the objective of the paper is to provide a theoretical model of cluster development that is informed by an appreciative interpretation of case studies it argues that entrepreneurs are a critical element in the formation of clusters entrepreneurs are important actors in the development of clusters as complex adaptive systems where the external resources associated with clusters are developed over time entrepreneurs who adapt to both constructive crises and new opportunities create the factors and conditions that facilitate their business interests and in turn contribute to the development of external resources the paper examines the initial factors that influence the decision to become an entrepreneur and examine how external factors influence the formation and location of high technology clusters feldman m p francis j

commercial bank ownership and performance in china this study examines the determinants of bank performance based on proxy variables that assess the quality of assets profitability liquidity and overall performance using a sample of 111 chinese commercial banks over the period of 2000 2012 we find that foreign banks appear to have better asset quality and overall performance although lower profitability compared to domestic banks in contrast the state owned banks tend to be more profitable and have better liquidity position compared with other domestic banks and foreign banks at bank level equity liability ratio exerts significant influence on overall bank performance while at the macroeconomic level per capital gdp gdp growth inflation and unemployment rates appear to have a bearing on bank performance

will trade sanctions reduce child labour the role of credit markets abstract we examine the interaction between credit markets trade sanctions and the incidence of child labour in a two good two period model with unequally wealthy households both poverty and poor education quality inter alia are important determinants of child labour the incidence of child labour decreases as we move from the case of borrowing constraints to the case in which poor households can borrow freely from rich ones and then to the case of perfect international credit markets trade sanctions can increase child labour especially among poor households a possibility that decreases as their access to credit improves

internal versus external capital markets this paper presents a framework for analyzing the costs and benefits of internal versus external capital allocation we focus pritnarily on comparing an internal capital market with bank lending while both represent centralized forms of financing in the former case the financing is owner provided while in the latter ceise it is not we argue that the ownership aspect of internal capital allocation has three important consequences 1 it leads to more monitoring than bank lending 2 it reduces managers entrepreneurial incentives and 3 it makes it easier to efficiently redeploy the assets of projects that are performing poorly under existing management

bank ratings what determines their quality this paper examines the quality of credit ratings assigned to banks by the three largest rating agencies we interpret credit ratings as relative assessments of creditworthiness and define a new ordinal metric of rating error based on banks expected default frequencies our results suggest that on average large banks receive more positive bank ratings particularly from the agency to which the bank provides substantial securitization business these competitive distortions are economically significant and contribute to perpetuate the existence of too big to fail banks we also show that overall differential risk weights recommended by the basel accords for investment grade banks bear no significant relationship to empirical default probabilities harald hau sam langfield and david marques ibanez

an economic analysis of child labor abstract this paper shows how poverty in combination with credit constraints can give rise to the phenomenon of child labor in developing countries it further shows how banning child labor can reduce the welfare of the households intending to send their children to work and suggests some alternative policies

a theory of socialistic internal capital markets abstract we develop a model of a two division firm in which the strong division has on average higher quality investment opportunities than the weak division we show that in the presence of agency and information problems optimal effort incentives are less powerful and thus managerial effort is lower in the strong division this leads the firm to bias its project selection policy against the strong division the selection bias is more severe when there is a larger spread in the average quality of investment opportunities between the two divisions

a reexamination of the conglomerate merger wave in the 1960s an internal capital markets view one possible explanation for bidding firms earning positive abnormal returns in diversifying acquisitions in the 1960s is that internal capital markets were expected to overcome the information deficiencies of the less developed capital markets examining 392 bidder firms during the 1960s we find the highest bidder returns when financially unconstrained buyers acquire constrained targets this result holds while controlling for merger terms and for different proxies used to classify firms facing costly external financing we also find that bidders generally retain target management suggesting that management may have provided companyspecific operational information while the bidder provided capital budgeting expertise
