control rights in complex partnerships this paper develops a theory of the allocation of authority between two players who are in a complex partnership that is a partnership which produces impure public goods we show that the optimal allocation depends on technological factors the parties valuations of the goods produced and the degree of impurity of these goods when the degree of impurity is large control rights should be given to the main investor irrespective of preference considerations there are some situations in which this allocation is optimal even if the degree of impurity is very low as long as one party s investment is more important than the other party s if the parties investments are of similar importance and the degree of impurity is large shared authority is optimal with a greater share going to the low valuation party if the importance of the parties investments is similar but the degree of impurity is neither large nor small the low valuation party should receive sole authority we analyze an extension in which side payments are infeasible we check for robustness of our results in several dimensions such as allowing for multiple parties or for joint authority and apply our results to interpret a number of complex partnerships including those involving schools and child custody jel d02 o23 h41 l31

children as collective goods and divorce settlements the failure of many divorced fathers to comply with court mandated child support awards has been identified as a major reason why a growing number of children live in poverty in female headed households this paper presents a model that seeks to explain why so many divorced fathers allow their children s welfare to suffer as a consequence of divorce the point of departure is the recognition that children are collective consumption goods from the point of view of the father and mother within marriage proximity and altruism serve to overcome the free rider problem associated with the provision of public goods however on divorce the noncustodial parent suffers a loss of control over the allocative decisions of the custodial parent and it is not feasible for the couple to achieve a pareto optimal allocation of their joint resources a model of optimal marriage contracts is constructed in which a couple decides on the allocation of resources within marriage and on the terms of a settlement in the event

royalty sharing and technology licensing in universities using data for 102 u s universities we show that royalty sharing arrangements cash flow rights vary substantially across universities and that they are largely unrelated to most observed university characteristics including faculty size quality research funding technology mix of the faculty and size of the technology licensing office however higher inventors royalty shares are associated with higher licensing income at the university controlling for other factors the results suggest that monetary incentives from inventions have real effects in the university sector jel o31 o34 l3 l01

the proper scope of government theory and an application to prisons when should a government provide a service in house and when should it contract out provision we develop a model in which the provider can invest in improving the quality of service or reducing cost if contracts are incomplete the private provider has a stronger incentive to engage in both quality improvement and cost reduction than a government employee has however the private contractor s incentive to engage in cost reduction is typically too strong because he ignores the adverse effect on noncontractible quality the model is applied to understanding the costs and benefits of prison privatization

the effect of child support policies on visitations and transfers recent research on child support issues has been concerned with normative problems involvingthe distribution of welfare between divorced parents and their children as well as with the assess ment of the behavioral responses of parents to child support orders and custody arrangements see e g del boca and flinn 1995 gar nkel and klawitter 1990 bartfeldt and gar nkel 1996 del boca 1996 del boca and ribero 1998 and flinn 2000 while there is bynow an extensive literature analyzing the e ects of child support policies on monetary transfersof noncustodial parents and the extent of compliance with child support orders little researchhas been done on the relationship between monetary transfers between parents and the divisionof the child s time while income transfers to the custodial parent are no doubt importantfor the child s consumption and general well being there exists considerable empirical evidencesuggesting that the division of the child s time between the parents has important e ects on thechild s welfare beller and graham 1993 there have been few analyses of this relationship weiss and willis 1985 provide one theoretical motivation for the positive relationship betweenthe noncustodial parent s contact time with the child and their level of transfers they claimthat increased contact time allows better monitoring of the custodial parent s expenditures onthe child which induces higher levels of transfers to the custodial parent we have developed a model del boca and ribero 1999 in which visitations and childsupport are the outcomes of a negotiation process whereby the father exchanges income forvisitation time institutional agents such as judges state legislatures etc can impact thewelfareofthemembersofthenonintactfamilybyalteringtheendowmentsofeachofthe1

reputation and the allocation of ownership we show that allocation of ownership matters even in a long term relationship where problems of opportunism are less severe unless agents are very patient ownership structure is chosen to give the agents best incentives to cooperate the optimal control structure of the static game restricts the gain from deviation to be the lowest but also the punishment will be minimal the worst ownership structure of the one shot game is good in the repeated setting because it provides the highest punishment but bad because the gain from deviation is also highest we show that when investment costs are very elastic partnership and a hostage type solution arise in equilibrium while when costs are moderately elastic the results of the one shot game apply

rationalizing child support decisions the authors provide a framework within which the child support compliance decisions of noncustodial fathers and the child support awards set by institutional agents can be coherently interpreted the model of child support transfers is able to capture qualitatively the features of the monthly payment distribution estimated parental decision rules are used to infer the implicit weights given by institutional agents to the postdivorce welfare of parents and children the authors find that the weight attached to the combined welfare of the custodial mother and child is significantly less than the weight given to the father s welfare in most sample cases copyright 1995 by american economic association

a theory of firm scope the formal literature on firm boundaries has assumed that ex post conflicts are resolved through bargaining in reality parties often simply exercise their decision rights we develop a model based on shading in which the use of authority has a central role we consider two firms deciding whether to adopt a common standard nonintegrated firms may fail to coordinate if one firm loses an integrated firm can internalize the externality but puts insufficient weight on employee benefits we use our approach to understand why cisco acquired stratacom a provider of new transmission technology we also analyze delegation

remedying education evidence from two randomized experiments in india this paper presents the results of a two year randomized evaluation of a large scale remedial education program conducted in mumbai and vadodara india the remedial education program hires young women from the community to teach basic literacy and numeracy skills to children who reach standard three or four without having mastered these competencies the program implemented by a ngo in collaboration with the government is extremely cheap it cost 5 dollars per child per year and is easily replicable it has been implemented in 20 indian cities and reached tens of thousands of children we find the program to be very effective on average it increased learning by 0 15 standard deviations in the first year and 0 25 in the second year the gains are the largest for children at the bottom of the distribution children in the bottom third gain 0 2 standard deviations in the first year and 0 32 in the second year in math they gain 0 51 standard deviation in the second year the results are similar in the two grade levels and in the two cities at the margin extending this program would be up to 12 16 times more cost effective than hiring new teachers authors

environmental disclosure and stock market liquidity evidence from arab mena emerging markets abstractthe objective of this study is to examine the impact of environmental disclosure levels on the stock market liquidity of arab middle eastern and north african mena companies for that a self constructed disclosure index was applied to the annual reports for the years 2010 2011 and 2012 and the bid ask spread was used as a proxy for stock market liquidity results indicate that levels of environmental disclosure in mena companies are quite low in addition using a sample of 276 firm year observations multivariate analysis shows that the higher the level of environmental disclosure provided in the annual reports the lower the spread between the market bid and ask prices thereby indicating an increase in stock market liquidity

randomized evaluations of educational programs in developing countries some lessons this paper reviews recent randomized evaluations of educational programs in developing countries including programs to increase school participation to provide educational inputs and to reform education it then extracts some lessons for education policy and for the practice and political economy of randomized evaluations

optimal ownership of public goods reconsidered consider a non governmental organization ngo that can invest in a public good should the government or the ngo own the public project in an incomplete contracting framework with split the difference bargaining besley and ghatak 2001 argue that the party who values the public good most should be the owner we demonstrate the robustness of their insight when the split the difference rule is replaced by the deal me out solution our finding is in contrast to the private good results of chiu 1998 and de meza and lockwood 1998 who show that the optimal ownership structure crucially depends on whether the split the difference rule or the deal me out solution is used

not for profit entrepreneurs abstract entrepreneurs who start new firms may choose not for profit status as a means of committing to soft incentives such incentives protect donors volunteers consumers and employees from ex post expropriation of profits by the entrepreneur we derive conditions under which completely self interested entrepreneurs opt for not for profit status despite the fact that this status limits their ability to enjoy the profits of their enterprises we also show that even in the absence of tax advantages unrestricted donations would flow to non profits rather than for profit firms because donations have more significant influence on the decisions of the non profits

government versus private ownership of public goods there has been a dramatic change in the division of responsibility between the state and the private sector for the delivery of public goods and services in recent years with an increasing trend toward contracting out to the private sector and public private partnerships this paper analyzes how ownership matters in public good provision we show that if contracts are incomplete then the ownership of a public good should lie with a party that values the beneets generated by it relatively more this is true regardless of whether this party is also the key investor or other aspects of the technology

power in a theory of the firm transactions take place in the firm rather than in the market because the firm offers power to agents who make specific investments past literature emphasizes the allocation of ownership as the primary mechanism by which the firm does this within the contractibility assumptions of this literature we identify a potentially superior mechanism the regulation of access to critical resources access can be better than ownership because i the power agents get from access is more contingent on their making the right investment and ii ownership has adverse effects on the incentive to specialize the theory explains the importance of internal organization and third party ownership

hospital ownership and public medical spending the hospital market is served by firms that are private for profit private not for profit and government owned and operated i use a plausibly exogenous change in hospital financing that was intended to improve medical care for the poor to test three theories of organizational behavior i find that the critical difference between the three types of hospitals is caused by the soft budget constraint of government owned institutions the decision makers in private not for profit hospitals are just as responsive to financial incentives and are no more altruistic than their counterparts in profit maximizing facilities my final set of results suggests that the significant increase in public medical spending examined in this paper has not improved health outcomes for the indigent i introduction the hospital market is served by firms that are private for profit private not for profit and publicly owned and operated in this paper i examine how a hospital s type of ownership influences its response to profitable opportunities that are created by changes in government policy the policy change that i exploit was designed to improve the quality of medical care for lowincome individuals by significantly increasing hospitals financial incentives to treat them this program also substantially increased the revenues of those hospitals that had been serving a disproportionate share of the indigent i use this plausibly exogenous change in government policy to test three different theories of organizational behavior and then to assess the impact of hospital behavioral responses on health outcomes the response of organizations to changes in government policy will have an important impact on the consequences of these policies this is likely to be especially true in the medical sector in which the federal state and local governments contract directly

economics an emerging small world we study the evolution of social distance among economists over the period 1970 2000 while the number of economists has more than doubled the distance between them which was already small has declined significantly the key to understanding the short average distances is the observation that economics is spanned by a collection of interlinked stars a star is an economist who writes with many other economists most of whom have few coauthors and generally do not write with each other

family specific investments and divorce with dynamically inconsistent households marital contracts and policy abstract this paper bridges two distinct areas of inquiry the economic theory of the family and behavioral research on time inconsistent preferences motivated by anecdotal and survey evidence suggesting that present bias plays a role in intra household decision making we propose a model in which hyperbolic discounting couples engage in home production activities thereby accumulating family specific capital over time at any given point in time the gains to continued marriage depend on the accumulated stock of this capital and a temporary random shock to match quality couples whose match quality deteriorates may choose to divorce and this is more likely to happen if past investments in family specific capital have been low we obtain three main sets of results first present biased preferences induce couples to underinvest in family specific capital and to overdivorce second sophisticated couples but not naive ones may choose to enter marriage on terms which make divorce more costly to obtain third the inefficiencies in the behavior of time inconsistent couples can be completely undone by means of earnings and divorce taxes that vary over the marital life cycle

environmental disclosures regulatory costs and changes in firm value abstract union carbide s chemical leak in bhopal india during december 1984 resulted in approximately 4 000 deaths and 200 000 injuries this study examines the market reaction of chemical firms other than union carbide to this catastrophe evidence indicates that a significant negative intra industry reaction occurred however firms with more extensive environmental disclosures in their financial report prior to the chemical leak experienced a less negative reaction than firms with less extensive disclosures this result suggests that investors interpreted such disclosures as a positive sign of the firm managing its exposure to future regulatory costs

to bundle or not to bundle commodity bundling is studied in an environment where the dispersion of valuations unambiguously decreases when two or more goods are sold as a bundle only bundling is more likely to dominate separately selling the goods if marginal costs are low relative to the average valuation or if the distribution of valuations is very peaked around the mean

costly bargaining and renegotiation we identify the inefficiencies that arise when negotiation between two parties takes place in the presence of transaction costs first for some values of these costs it is efficient to reach an agreement but the unique equilibrium outcome is one in which agreement is never reached secondly even when there are equilibria in which an agreement is reached we find that the model always has an equilibrium in which agreement is never reached as well as equilibria in which agreement is delayed for an arbitrary length of time finally the only way in which the parties can reach an agreement in equilibrium is by using inefficient punishments for some of the opponent s deviations we argue that this implies that when the parties are given the opportunity to renegotiate out of these inefficiencies the only equilibrium outcome which survives is the one in which agreement is never reached regardless of the value of the transaction costs

does asset ownership always motivate managers outside options and the property rights theory of the firm this paper studies the grossman hart moore ghm property rights approach to the theory of the firm under alternating offers bargaining when managers can pursue other occupations while negotiating over the division of the gains from cooperation the ghm results obtain if taking the best alternative job terminates bargaining outcomes are very different sometimes an agent with an important investment decision should not own the assets he works with sometimes independent assets should be owned together sometimes strictly complementary assets should be owned separately

nature of human capital technology and ownership of public goods abstract besley and ghatak 2001 show that a public good should be owned by the agent who values the public good the most irrespective of technological factors in this paper we relax their assumptions in a natural way by allowing the agents to be indispensable and we show that the relative valuations are not the sole determinant of an optimal ownership structure but also the nature of human capital and technology matter

the economics of child custody i develop a model of marriage in which spouses decide on investments in child quality during marriage and on the allocation of child custody should they divorce the custodial allocation determines the share of the marital surplus each spouse appropriates which in turn influences spouses investment incentives the custodial allocation therefore has both distributional and efficiency consequences i derive the equilibrium investments and optimal custodial allocation and identify three channels through which making divorce easier affects child welfare investments in child quality during marriage the likelihood of divorce and the allocation of custody if divorce occurs

government versus private ownership of public goods the role of bargaining frictions abstract the government and a non governmental organization ngo can invest in the provision of a public good who should be the owner of the public project in an incomplete contracting model in which ex post negotiations are without frictions the party that values the public good most should be the owner regardless of technological aspects however under the plausible assumption that there are bargaining frictions the optimal ownership structure depends on technological aspects and on the parties valuations we show that the differences between incomplete contracting models with public goods and private goods are thus smaller than has previously been thought

who owns the media the authors examine patterns of media ownership in 97 countries around the world they find that almost universally the largest media firms are controlled by the government or by private families government ownership is more pervasive in broadcasting than in the printed media government ownership is generally associated with less press freedom fewer political and economic rights inferior governance and most conspicuously inferior social outcomes in education and health the adverse effects of government ownership on political and economic freedom are stronger for newspapers than for television the adverse effects of government ownership of the media do not appear to be restricted solely to instances of government monopoly the authors present a range of evidence on the adverse consequences of state ownership of the media state ownership of the media is often argued to be justified on behalf of the social needs of the disadvantaged but if their findings are correct increasing private ownership of the media through privatization or by encouraging the entry of privately owned media can advance a variety of political and economic goals especially those of meeting the social needs of the poor

how to design infrastructure contracts in a warming world a critical appraisal of public private partnerships we analyze how long term uncertainty for example regarding future climate conditions affects the design of concession contracts and organizational forms in a principal agent context with dynamic moral hazard limited liability and irreversibility constraints the prospect of future uncertain productivity shocks on the returns on the firm s effort creates an option value of delaying efforts a course that exacerbates agency costs contracts and organizational forms are drafted to control this cost of delegated flexibility the possibility for the agent to delay investment in response to uncertainty and irreversibility also elicits preference for unbundling different stages of the project through short term contracts our analysis is relevant to infrastructure sectors that are sensitive to changing weather conditions and sheds a pessimistic light on the relevance of public private partnerships in this context

csr disclosure and sustainable supplier management a small to medium sized enterprises perspective the respective literatures on corporate social responsibility csr disclosure and sustainable supplier management have grown in recent years but little scholarly attention has been paid to the li

public goods and the hold up problem under asymmetric information an agent can make an observable but non contractible investment a principal then offers to collaborate with the agent to provide a public good private information of the agent about his valuation may either decrease or increase his investment incentives depending on whether he learns his type before or after the investment stage

the deviation of production prices from labour values some methodology and empirical evidence contrary to what is expected from indirect evidence and two commodity hypothetical examples the evdie nce provided in this paper supports david ricardo s empirical proposi tion that relative prices of production are mainly determined by labo r value ratios the results obtained indicate that a 1 percent change in profit rate will cause relative prices to change up to 2 percent and as the profit rate on gross capital is approximately 5 percent o ne ends up with a 90 percent labor theory of value the empirical evidence refers to the yugoslav economy but the factors that determ ine the deviations considered turn out to be of the same order of mag nitude as in other economies copyright 1987 by oxford university press
