risk private information and the family in the last fifteen years our understanding of the behavior of households in both highand low income countries has increased significantly econometric studies contributing to this body of knowledge concerned with the determinants of such behavior as labor supply fertility health and food consumption however have generally taken the structure of the household as exogenously given while some progress has been made concerning how changes in the legal structure alter patterns of family formation and breakup the wide variety of family organizations observed across countries of the world or the evolution of family structure within countries cannot be readily explained by existing models while some economists have suggested that organizations based on kinship can be understood in terms of transaction economies yoram ben porath 1980 robert pollak 1985 there are now few precise implications of this approach and little or no evidence of its usefulness for predicting or explaining the existence of any particular family structure in specific settings characterized by their natural endowments and or legal structure in this paper i discuss some recent studies of family and household organization in one specific context rural india that have sought to formulate a model of household structure based on the need for individuals in lowincome private information settings to protect themselves against intertemporal fluctuations in resources arising from the natural vagaries of water supply i also present some new evidence on the relationship between family arrangements and measured risk characteristics of the agricultural environment in these settings while many economists have highlighted risk and information consideration in the study of such formal rural institutions as sharecropping permanent servitude and contractual interlinking studies of these individual contractural arrangements have ignored the family itself as a risk mitigating institution moreover much of this literature has been solely concerned with ex ante measures to reduce risk contractual instruments or production factors that reduce the effects of variability in the exogenous production input rainfall on income mechanisms serving to preserve consumption stability ex post in the face of variability in realized income have been neglected

indirect effects of an aid program how do cash transfers affect ineligibles consumption cash transfers to eligible households indirectly increase the consumption of ineligible households living in the same villages this effect operates through insurance and credit markets ineligible households benefit from the transfers by receiving more gifts and loans and by reducing their savings thus the transfers benefit the local economy at large looking only at the effect on the treated underestimates the impact one should analyze the effects of this class of programs on the entire local economy rather than on the treated only and use a village level randomization rather than selecting treatment and control subjects from the same community

competition and corporate performance are people right to think that competition improves corporate performance my investigations indicate first that there are some theoretical reasons for believing this hypothesis to be correct but they are not overwhelming furthermore the existing empirical evidence on this question is weak however the results reported here based on an analysis of around 670 u k companies do provide some support for this view most important i present evidence that competition as measured by increased numbers of competitors or by lower levels of rents is associated with a significantly higher rate of total factor productivity growth

specific experience household structure and intergenerational transfers farm family land and labor arrangements in developing countries data from indian rural household survey was used to test th hypothesis that the coexistence in traditional rural societies of extended intergenerational families infrequent land sales and high reliance on family members as farm laborers is the result of the economic advantages which accrue from the knowledge gained by farming a particular ploy of land over a long period of time the land specific experience of elderly members of a intergenerational household who farmed the land as a child and then as an adult are expecially critical in adverse weather years most previous investigators attributed the existence of multigenerational households the use of family members rather than hired laboreds and the infrequency of land sales to deficiencies in the market i e labor market imperfections and an absence of capital insurance and asset markets in the present investigations these same characteristics are viewed as having an economic advantages a model for estimating the contribution of the experience of the elderly household members to agricultural profits was developed and applied to data from a 3 year panel study of 2900 indian rural farm households the data was collected between 1968 71 by the national council of applied economic research the survey collected information on farm profits farm inputs demographic characteristics and the effects of weather conditions on profits a major limitation of the study was a lack of information on the duration of land ownership age of household members was substituted as a proxy for duration of ownership findings were consistent withe the hypothesis in poor agricultural years gross returns for households which contained an elderly household member were greater than the gross returns for comparable households which did not contain an elderly member the economic advantages of specific knowledge embodied in the experienced elderly farmer were comparable to the economic advantages which accrued to households whose members were more educated the hypothesis cannot fully explain the existence of intergenerational families since there is a relatively large proportion of such families among nonfarm families in many countries including india findings suggest that intergenerational families may provide for more occupational diversity and thereby reduce income risks the specific experience hypothesis has policy implications if technological changes are introduced the value of specific experience may be lost and the frequency of intergenerational households may decline the hypothesis may also explain why farmers are reluctant to agree to land redistribution and consolidation schemes this reluctance may disappear after sufficient technological change has occurred

child fostering in africa when labor and schooling motives may coexist abstract the paper proposes a theoretical framework for understanding purposive child fostering in africa whereby a non orphaned child is sent to live temporarily with relatives in the model adults decide whether to foster in or out a child in conjunction with other household choices e g own time allocation between market and non market activities children s amount of work and schooling by allowing for positive externalities from fostering and thus asymmetric motives for fostering in labor and out human capital the proposed framework predicts that school age children are sent to better off households and that some families may foster in and out simultaneously the model identifies the conditions under which all actors involved children included may benefit from fostering arrangements but also points to situations where fostering may become an opportunity to marginalize a subset of children the paper aims to provide a sound theoretical foundation that sheds light on why there exists mixed empirical evidence on the effects of fostering on children s well being and cautions against demonizing non parent residence as unequivocally detrimental to children

alternative regulatory methods and firm efficiency stochastic frontier evidence from the u s electricity industry the use of incentive regulation and other alternative regulatory programs in u s electricity markets has grown during the past two decades within a stochastic frontier framework i investigate the effect of individual programs on the technical efficiency of a large set of coal and natural gas generation units i find that those programs tied directly to generator performance and those that modify traditional fuel cost pass through programs to provide a greater incentive to reduce fuel costs are associated with greater efficiency levels other programs have no statistical association with efficiency levels

ex ante and ex post labor supply response to risk in a low income area abstract this paper tests for ex ante and ex post labor supply responses to weather risk for rural indian farm households the analysis uses panel data on 2115 households spanning 13 states in rural india merged with a 22 year series of district level rainfall data ex ante households facing riskier distributions of rainfall are more likely to participate in the labor market ex post unexpectedly bad weather and low rainfall increase labor force participation

precautionary behavior migrant networks and household consumption decisions an empirical analysis using household panel data from rural china abstract we develop a test of precautionary behavior in the consumption decisions of rural agricultural households among surveyed households facing a median level of consumption risk 10 of savings can be attributed to a precautionary motive and this increases to 15 for households with consumption per capita below the poverty line we next use distant lags of local rainfall shocks uncorrelated with current consumption growth to identify the size of migrant networks outside the village and then present evidence that both poor and nonpoor households engage in less precautionary saving as the size of the village migrant network increases

sons as widowhood insurance evidence from senegal exploiting original data from a senegalese household survey we provide evidence that fertility choices are partly driven by women s needs for widowhood insurance we use a duration model of birth intervals to show that women most at risk in case of widowhood intensify their fertility shortening birth spacing until they get a son insurance through sons might entail substantial health costs since short birth spacing raises maternal and infant mortality rates

the crowding out effect of formal insurance on informal risk sharing an experimental study abstract this paper investigates the crowding out effect of formal insurance on informal risk sharing arrangements via theory and laboratory experiment our model and simulation predict that the crowding out of private transfers is often more than one for one and will reduce the total risk coverage furthermore the existence of a moderate degree of altruism exaggerates the crowding out effect especially when there is an ex ante income inequality these predictions are mostly supported by the laboratory experiment except that the crowding out effect is not more than one for one and hence the total risk coverage is not significantly reduced by formal insurance

generating efficiency economic and environmental regulation of public and private electricity generators in spain abstract economic regulation of firms with market power has placed increasing emphasis on incentive based regulation such as price caps we focus on the effect of regulation as distinct from ownership and identify the effect of two different regulatory schemes on both publicly and privately owned spanish electricity generators publicly owned generators were more efficient under cost of service regulation private but not public firms responded to incentive regulation by increasing efficiency bringing their productivity to similar levels we introduce some novelty in modelling efficiency including three pollutants and declared plant availability as outputs and we test for the effect of environmental regulation in reducing pollutants

assortative matching and risk sharing abstract this paper explores the sorting patterns in a two sided matching market where agents facing different risks match to share them when preference belongs to the class of harmonic absolute risk aversion hara the risk premium is perfectly transferable within each partnership thus a stable match minimizes the social cost of risk in the systematic risk model where agents are ranked by their holdings of a common risky asset the convexity of the joint risk premium in joint risk size leads to negative assortative matching nam in the idiosyncratic risk model where agents are ranked by their independent riskiness in the sense of second order stochastic dominance ssd nam arises when preference exhibits decreasing absolute risk aversion dara in the sense of ross and riskier background risk leads to more risk averse behavior however nam may fail to arise when riskier background risk leads to more risk tolerant behavior

insurance market efficiency and crop choices in pakistan this paper tests the efficiency of insurance markets in the pakistan punjab by examining how crop choices are affected by the presence of price and yield risk we estimate reduced form and structural models of crop choices although we cannot reject the hypothesis that village members efficiently share risk among themselves production choices are shown to depend on risk existing risk sharing and selfinsurance mechanisms thus imperfectly protect punjab farmers against village level shocks results also indicate that households respond to consumption price risk thereby suggesting that empirical and theoretical work on risk should avoid putting an exclusive emphasis on yield and output price risk

periodic high risk as a cause of fertility decline in a changing rural environment survival strategies in the 1980 1983 south indian drought in the attempt to explain persistent high fertility in much of the third world attention has been drawn both to current returns from child labor and to the mitigation or avoidance of future risks the latter can be subdivided into meeting emergencies while the parental generation is still of working age and providing for old age or even safeguarding the transmission of family property on parental death the problems of old age have recently received most attention and they may well be of paramount importance in many societies yet in a research program that we have conducted in rural south india since 1979 the reasons given for demographic behavior have more frequently emphasized the need to plan strategies to meet periodic crisis than to ensure old age support 2 nevertheless one should not underemphasize the latter merely because the problem is predictable and the solutions understood in the study area for the great majority of the aged the support system still worked well 3 in contrast in our investigations of marriage fertility control and education we repeatedly discovered that a fundamental consideration with regard to parental decisions in these areas was to strengthen the ability of the family to withstand periodic crises 4 by far the most important type of crisis in this dry drought prone area was recurrent famines resulting

on the economics of nonmarket transfers the role of altruism abstract we examine altruistically motivated consumption transfers in an effort to account for nonmarket transfers we find that altruistic linkages lead to autonomous negotiation free transfers and that such transfers positively respond to stronger altruism we also find that given fairly natural assumptions concerning the altruism parameters mutual altruism does not necessarily result in group social harmony even though its rise narrows the conflict range in spite of enhanced transfers prompted by such a rise both parties may end up worse off these results help explain why in some social environments a shift toward market oriented transfers and exchanges may be quicker than in others as the disadvantages decline in utility associated with intragroup altruistic linkages outweigh the advantages

the role of policy in energy transitions lessons from the energy liberalisation era the aim of this paper is to discuss the period of energy privatisation and liberalisation which began in the 1980s within its wider historical context the key issues are what has been learned from this recent period and how significant is it in the light of an energy transition to low carbon energy system by 2050 energy liberalisation has led to positive and globally widespread but modest efficiency gains but a lack of clearly visible direct benefits to households in many countries it has significantly improved the governance of monopoly utilities via independent regulators the prospects for competition and innovation and the quality of policy instruments for environmental emissions control through the emergence of trading mechanisms we conclude that it is not liberalisation per se that will determine the movement towards a low carbon energy transition but the willingness of societies to bear the cost which will be significant no matter what the extent of liberalisation

motivations to remit evidence from botswana in this article a theory of motivations to send remittances is described and tested with data from botswana altruism is one of the motivations tested and found to be an insufficient explanation for remittances among migrants in botswana a refinement of the model stipulates a modified altruism or enlightened self interest in this model the relationship between the migrant and family is tempered by an implicit understanding of mutual benefit the household strategy may be to encourage some members to migrate as a means of spreading risk and sharing gains the household strategy is similar to an insurance policy where migration is to places where market potential is high the risks incurred might be high the example is given of migration during a drought in botswana migrant remittances were greater in households with more cattle or households with more to lose drought alone was not statistically related to remittances increases in remittances were related to increased levels of education it is suggested that repayment was the motive for parents investment in migrants education migrants gains are identified as the potential for an inheritance the security of channeling investments through a trusted family member and security in having a home to return to it is pointed out that the altruism and family remittances from urban migration were strategies that bridged the simple dynamic of either urban development or rural development impacting on family welfare it is suggested that household models of economy adopt some measure to express the relationship of household wealth to remittances from urban migrants

group size and the efficiency of informal risk sharing this paper seeks to understand and test empirically the relationship between group size and informal risk sharing models of informal risk sharing with limited commitment and grim trigger punishments upon deviation imply that larger groups provide better insurance however when subgroups of households can credibly deviate so that sustainable informal arrangements ought to be coalition proof the relationship between group size and the amount of insurance is unclear building on genicot and ray 2003 we show that this relationship is theoretically ambiguous we then investigate it empirically using data on the size of the sibships of the household head and spouse in rural malawi to identify the relevant potential risk sharing group we exploit a social norm among the main ethnic group in our sample that the wife s brothers play a key role in ensuring her household s wellbeing we find that households where the wife has many brothers are poorly insured against crop loss events we fail to uncover a similar relationship for the wife s sisters ruling out that our findings are driven by wives with many siblings e g brothers simply having poorer extended family networks a simple calibration exercise indicates that the threat of coalitional deviations can explain our empirical findings

malmquist indices of productivity change in the uk gas industry before and after privatization the uk government s privatization programme was justified in terms of potential efficiency gains this paper concentrates on measures of technical efficiency in the regions of the uk natural gas industry before and after privatization and the associated regulatory changes it uses non parametric frontier analysis and malmquist indices to show that the rate of productivity growth increased significantly after privatization however the differences in technical efficiency amongst regions remain suggesting that failure to break up the industry has sacrificed potential gains from direct competition or indirect competition through yardstick regulation

the british electricity experiment the privatization of the electricity supply industry esi in britain which began 1990 is in itself an unremarkable event much of the esi is privately owned in several european countries and in the united states and the u k privatization program has embraced utilities since 1984 when british telecom was privatized the thing that is remarkable about recent policy toward the industry is the radical nature of the regulatory reform accompanying privatization a vertically integrated administered generation and transmission structure was replaced overnight on march 31 1990 by one that is deintegrated and market based generation and transmission have been separated and there has been an attempt to establish competition in generation a number of countries have been moving gradually in the direction of encouraging competition but nowhere else have such dramatic changes been implemented so quickly

no toilet no bride intrahousehold bargaining in male skewed marriage markets in india abstract haryana state in india is characterized by widespread discrimination against women including a severe population level sex imbalance in this context an innovative social marketing campaign which targeted pro sanitation messages to households active in local marriage markets was implemented with the goal of increasing toilet ownership this paper estimates the impact of this program known colloquially as no toilet no bride on household level latrine ownership private sanitation coverage in haryana increased by 21 specifically among households with boys active on the marriage market this effect is larger and concentrated in marriage markets where women are relatively scarce and absent when women are relatively abundant which together suggest the program operated by successfully linking sanitation outcomes with marriage market competition induced by local scarcities of women due to male biased sex ratios

a dynamic equilibrium model of imperfectly integrated financial markets abstract this paper analyzes the determination of global equity portfolios and stock returns in the context of imperfectly integrated stock markets we consider a continuous time two country endowment economy where the level of financial integration is captured by a proportional tax on foreign dividends despite the investor heterogeneity induced by this tax we obtain approximate closed form expressions for asset prices and characterize equity holdings and the joint process followed by country level stock returns in equilibrium our model is consistent with a broad range of empirical findings on international financial integration when the endogenous cross country return correlation is high small frictions in equity markets can generate a substantial home bias in portfolios in the baseline version of our model the cross country return correlation is driven by the fundamental correlation and portfolio rebalancing in a two good extension of the model the adjustment of relative good prices can generate a high stock return correlation even for a low level of fundamental correlation magnifying the impact of the financial friction on portfolios we assess the quantitative performance of the model in a calibration exercise using data from g7 countries

income transfers of chinese rural migrants some empirical evidence from jinan this paper explores the determinants of migrant remittances to rural households using data on male migrant workers drawn from the jinan municipality in shandong province in the summer of 1995 the majority of migrants are found to retain close links with their rural households with 85 remitting some income in the 12 months preceding the survey date the transfers accounted for over a third of urban labour earnings a number of models are used to undertake the estimation of remittance functions no evidence of altruistic behaviour is uncovered and evidence for exchange and coinsurance theories is mixed labour earnings proved the most robust determinant of the level of remittance and the remittance wage elasticity calculated is found to be at the top end of the range of estimates obtained in the literature

dynamic equilibrium with two stocks heterogeneous investors and portfolio constraints we study dynamic equilibrium in a lucas economy with two stocks two heterogeneous constant relative risk aversion investors and portfolio constraints we focus on margin and leverage constraints which restrict access to credit we find a positive relationship between the amount of leverage in the economy and magnitudes of stock return correlations and volatilities tighter constraints generate rich patterns in correlations and volatilities make them less countercyclical increase risk premia proportionally to assets margins and increase prices of low margin assets more than prices of high margin assets we derive closed form solutions for the unconstrained case and the case of leverage constraints

technology market and community in contract choice rice harvesting in the philippines an attempt to incorporate institutional change as an endogenous factor in the economic system is a frontier of economics a perspective from new institutional economics is to view the evolution of institutions as having emerged from the efforts of individuals and groups who aimed to achieve more efficient resource allocation and to establish claims for larger income shares these efforts are mobilized in response to changes in economic variables such as resource endowments and technology under the constraints of existing social and cultural norms a massive body of literature has been accumulating in this field of research including game theories collective action principal agent contracting and transaction costs however the theoretical developments have not been paralleled by empirical analysis constrained by the difficulty of testing on purposively collected microeconomic data empirical studies have largely been based on broad historical observations with the results being rather conjectural in this article we attempt to fill this gap by a case study on changes in labor contracts that have been used for rice harvesting in the philippines for the three decades since the advent of the green revolution in the late 1960s the major hypotheses we test are as follows a dramatic changes in the labor contract arrangements were induced in order to reduce disequilibrium between labor s marginal costs and returns created by changes in rice production technology and market wage rates b villagers chose specific labor contract arrangements that were consistent with the norms of the particular rural village communities and c contract forms changed according to changes in community norms some results that pertain to the first decade of the green revolution had

migration risk and liquidity constraints in el salvador abstract this article utilizes panel data from el salvador to investigate the use of transnational migration as an ex post risk management strategy i show that adverse agricultural conditions in el salvador increase both migration to the united states and remittances sent back to el salvador i show that in the absence of any agricultural shocks the probability that a household sent members to the united states would have decreased on average by 24 26 i also show that the 2001 earthquakes reduced net migration to the united states a one standard deviation increase in earthquake damage reduced the average probability of northward migration by 37 11 the evidence suggests that the effects of the earthquakes had more to do with households retaining labor at home to cope with the effects of the disaster than with the earthquakes disrupting migration financing

the financial and operating performance of privatized firms during the 1990s this study compares the pre and postprivatization financial and operating performance of 85 companies from 28 industrialized countries that were privatized through public share offerings for the period from 1990 through 1996 we document significant increases in profitability output operating efficiency and dividend payments and significant decreases in leverage ratios for our full sample of firms after privatization and for most subsamples examined capital expenditures increase significantly in absolute terms but not relative to sales employment declines but insignificantly combined with results from two previous directly comparable studies these findings strongly suggest that privatization yields significant performance improvements during the past two decades the privatization of state owned enterprises has moved from being a radical almost desperate policy initiative of the thatcher government in britain to being an accepted economic policy for governments of all ideological stripes according to gibbon 1998 860 billion has been raised by governments worldwide through privatizations with the bulk of this total coming since 1987 and at least one commentator roche 1996 predicts that no less than 6 trillion will be raised through privatizations over the next two decades in 1997 alone sales of public enterprises totaled a record 161 billion worldwide with more than 110 billion of the total coming during the second half of the year and 1998 s total of almost 140 billion indicates that the pace shows no sign of slackening as we approach a new millennium

managerial incentives and product market competition are imperfectly competitive leibenstein 1966 claims that there may be a substantial amount of x inefficiency where x inefficiency measures the degree to which actual profits depart from the maximum of profits that could be obtained if all operations in the firm were carried out at minimal costs he offers empirical evidence from case studies showing that the welfare loss due to organizational slack is of an order of magnitude bigger than the welfare loss due to monopolistic price distortions on imperfectly competitive markets these results support the common presumption that increasing competition reduces organizational and in particular managerial slack however this early literature does not offer a theoretical explanation for the link between competition and managerial incentives in particular it ignores the fact that managerial incentives can be affected by the design of an incentive scheme in this paper i derive the optimal incentive scheme for a manager as a function of the competitiveness of the environment in which his firm operates the basic impact of increased competition is that it reduces the profits of a firm this has two effects in the model first if a firm has high costs then the reduction of profits may be sufficient to render the firm unprofitable so the probability that it has to be liquidated goes up this unambiguously induces the manager of the firm to work harder for a cost reduction in order to avoid liquidation and to keep his job second the reduction in profits may affect

objectives and incentives evidence from the privatisation of great britain s power plants abstract does privatization increase plant productivity because the private owner s objective is different or because they are better able to control management and is privatization sufficient to improve productivity or is it only effective in combination with competition we answer these questions using the quasi experiment of great britain s electricity industry privatization to separate the effect of a change in objectives from a change in incentives we assume that the former only affects labor but not fuel productivity and assuming that effective competition was only introduced after privatization we are able to separately identify the effects of privatization and competition we find that privatization increased labor but not fuel productivity evidence for the importance of objectives there is no evidence that the introduction of effective competition after privatization increased labor or fuel productivity evidence that privatization increases productivity by itself

two trees with heterogeneous beliefs spillover effect of disagreement in a model where investors disagree about the fundamentals of two stocks the state price density depends on investor disagreements for both stocks especially the larger stock this implies that disagreement among investors in a large firm has a spillover effect on the pricing of other stocks owned by these investors the pricing effects of investor disagreements crucially depend on the average belief biases empirical findings support the novel model prediction of a disagreement spillover effect and help reconcile some mixed evidence in the literature

credit constraints job mobility and entrepreneurship evidence from a property reform in china this paper provides new evidence on the impact of private property rights on entrepreneurship i explore this issue in the context of a housing reform in urban china that allowed state employees renting state owned housing the opportunity to buy their homes at subsidized prices using the reform as an exogenous change in the capital constraints and mobility costs that inuence individuals entry

the lucas orchard this paper investigates the behavior of asset prices in an endowment economy in which a representative agent with power utility consumes the dividends of multiple assets the assets are lucas trees a collection of lucas trees is a lucas orchard the model generates return correlations that vary endogenously spiking at times of disaster since disasters spread across assets the model generates large risk premia even for assets with stable cashflows very small assets may comove endogenously and hence earn positive risk premia even if their cashflows are independent of the rest of the economy i provide conditions under which the variation in a small asset s price dividend ratio can be attributed almost entirely to variation in its risk premium

vertical and horizontal scope economies in the regulated us electricity power industry this paper investigates vertical economies between generation and distribution of electric power and horizontal economies between different types of power generation in the u s electric utility industry our quadratic cost function model includes three generation output measures hydro nuclear and fossil fuels which allows us to analyze the effect that generation mix has on vertical economies our results provide sample mean estimates of vertical economies of 8 1 and horizontal economies of 5 4 an extensive sensitivity analysis is used to show how the scope measures vary across alternative model specifications and firm types

partial privatization and firm performance most privatization programs begin with a period of partial privatization in which only non controlling shares of firms are sold on the stock market since management control is not transferred to private owners it is widely contended that partial privatization has little impact this perspective ignores the role that the stock market can play in monitoring and rewarding managerial performance even when the government remains the controlling owner using data on indian state owned enterprises we find that partial privatization has a positive impact on profitability productivity and investment widespread privatization in recent decades has generated a large empirical literature concerning the effect of ownership on firm performance most studies find that privatization has a positive impact on the profitability and efficiency of firms see megginson and netter 2001 for a recent survey 1 the firms in these studies have had a majority of their assets privatized and control rights have been transferred from the government to private owners surprisingly little is known about the effect of partial privatization where the government remains the controlling owner this paper seeks to address this gap in the literature by investigating whether the performance of state owned enterprises in india is affected by the sale of non controlling equity stakes on the stock market

on the valuation of long dated assets i show that the pricing of a broad class of long dated assets is driven by the possibility of extraordinarily bad news this result does not depend on any assumptions about the existence of disasters nor does it apply only to assets that hedge bad outcomes indeed it applies even to long dated claims on the market in a lognormal world if the market s sharpe ratio is higher than its volatility as appears to be the case in practice

differences of opinion and international equity markets we develop an international financial market model in which domestic and foreign residents differ in their beliefs about the information content in public signals we determine how informational advantages of domestic investors in the interpretation of home public signals affect equity markets we evaluate the ability of our model to generate four international finance anomalies i the co movement of returns and capital flows ii home equity preference iii the dependence of firm returns on home and foreign factors and iv abnormal returns around foreign firm cross listing in the home market their relationships with empirical differences of opinion proxies are consistent with the model received january 15 2011 editorial decision may 16 2016 by editor geert bekaert

a two season agricultural household model of output and price uncertainty abstract this paper presents a two season model of a household s production consumption labor supply and storage decisions in an environment of output and price risk the analytical results in this study are markedly different from those of models prevalent in the mainstream of the agricultural household literature the empirical analysis that uses panel data from a village in india provides support for the theoretical results and underscores the seasonal dimension of the farmers choice problems the results also show that ignoring risk or risk averse preferences may introduce substantial downward bias in optimal response estimates

a theory of privatisation public enterprises around the world have proved to be highly inefficient primarily because they pursue strategies such as excess employment that satisfy the political objectives of politicians who control them privatization of public enterprises can raise the cost to politicians of influencing them since subsidies to private firms necessary to force them to remain inefficient are politically harder to sustain than wasted profits of the state firms in this way privatization leads to efficient restructuring of firms moreover privatization is more effective when combined with a tight monetary policy and when the new owners of firms are profit maximizing investors rather than their employees or even managers copyright 1996 by royal economic society

determining the generalized discount rate for risky projects it is widely recognized that the evaluation of risky projects critically depends on how the riskiness of future benefits is treated standard discounting theories are based on the assumption that risks that are uncorrelated with aggregate risk are diversified so that projects idiosyncratic risk is not priced however this may not be true for long term risky projects such as those with persistent idiosyncratic shocks in this study we investigate the impact of both aggregate risk and nondiversifiable idiosyncratic risk on the discount rate for risky projects we extend the generalized discount rate to the case of persistent shocks a particular advantage of the generalized discount rate is that it can be applied in the setting of incomplete markets we show that nondiversifiable idiosyncratic risk reduces the discount rate and increases the present value of projects future uncertain benefits we further apply our findings to the evaluation of emissions reduction projects

contingent loan repayment in the philippines abstract using data from the philippines this article seeks to understand how households in the study area apparently manage to avoid falling into a debt trap in spite of frequent borrowing findings suggest that this is achieved via three institutional features first most informal debt carries no interest second for all debts repayment is postponed in case of a borrower s difficulty this is the only insurance feature of debt repayment third while debt principal is seldom forgiven or reduced interest bearing debt does not carry additional interest if debt repayment is delayed this prevents interest charges from accumulating and debt from snowballing

factor loading uncertainty and expected returns firm specific information can affect expected returns if it affects investor uncertainty about risk factor loadings we show that a stock s expected return is decreasing in factor loading uncertainty controlling for the average level of its factor loading when loadings are persistent learning by investors can induce time series variation in price dividend ratios expected returns and idiosyncratic volatility even when the aggregate risk premium is constant and fundamental shocks are homoscedastic consistent with our predictions we estimate that average annual returns of a firm with the median level of factor loading uncertainty are 400 to 525 basis points lower than a comparable firm without factor loading uncertainty the author 2012 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please e mail journals permissions oup com oxford university press

land taxes output taxes and sharecropping was henry george right economists have generally argued that if a land tax is administratively feasible then to increase efficiency it should be used to the exclusion of output taxes this article shows that underlying this policy prescription is the assumption that institutions for pooling and spreading production risks are perfect when account is taken of the imperfections in those institutions some use of output taxes will be pareto superior to a pure land tax regime and may induce higher output as well henry george was wrong these results generally apply even when the land tax is indexed to regional output and when land is farmed under sharecropping even in these cases a move from a pure land tax to a mix of land and low output taxes will reduce pre existing distortions in both consumption and production arising from the imperfection in risk markets

the determinants of the cost efficiency of electric generating plants a stochastic frontier approach this article provides a detailed analysis of generation plant operating cost efficiency over the period 1988 1997 i estimate a stochastic frontier cost function together with a model of plant inefficiencies to measure the operating efficiencies of individual plants and identify factors that are associated with variations in plant efficiencies i find evidence that plant efficiencies are associated with capacity utilization of the plant the number of plants under utility management and ownership form i also find that regulatory restructuring activity in certain states is associated with improvements in plant operating performance the purpose of this article is to provide a detailed analysis of the operating cost efficiencies of electricity generating plants over the period 1988 1997 i estimate the operating efficiencies of fossil fueled steam generating plants and examine factors that influence plant operating performance i use the estimation procedure of battese and coelli 1995 to simultaneously estimate a stochastic frontier cost function and a function relating plant efficiency levels to plant specific factors and other explanatory variables a comprehensive data set allows me to investigate the influence of capacity utilization ownership form and utility experience on plant efficiency levels since significant regulatory change in the electricity industry had begun during this time period i also investigate the impact of state level regulatory change on plant operating efficiency a number of authors have analyzed the efficiencies of electricity generating plants relative to a best practice frontier including kopp and smith 1980 schmidt and lovell 1979 stevenson 1980 cote 1989 reifschneider and stevenson 1991 hammond 1992 pollitt 1995 and fire grosskopf and logan 1983 1985 these studies find considerable evidence of inefficiency in electricity generation during the 1960s and 1970s the present study provides more recent information regarding generating plant efficiencies during a period of significant regulatory and structural change studies investigating the determinants of power plant departures from the frontier have focused primarily on the effects of ownership mode pollitt 1995 provides a comprehensive review of these studies reifschneider and stevenson 1991 examine the impact on cost efficiency of a number of variables including the capacity utilization of the firm s generating facilities more recently knittel 2001 examines the impact of incentive regulation on plant efficiency levels steiner

consumption smoothing migration and marriage evidence from rural india a significant proportion of migration in low income countries particularly in rural areas is composed of moves by women for the purpose of marriage we seek to explain these mobility patterns by examining marital arrangements among indian households in particular we hypothesize that the marriage of daughters to locationally distant dispersed yet kinship related households is a manifestation of implicit interhousehold contractual arrangements aimed at mitigating income risks and facilitating consumption smoothing in an environment characterized by information costs and spatially covariant risks analysis of longitudinal south indian village data lends support to the hypothesis marriage cum migration contributes significantly to a reduction in the variability of household food consumption farm households afflicted with more variable profits tend to engage in longer distance marriage cum migration the hypothesized and observed marriage cum migration patterns are in dissonance with standard models of marriage or migration that are concerned primarily with search costs and static income gains

an exogeneity test for a simultaneous equation tobit model with an application to labor supply a test of weak exogeneity in the simultaneous equation tobit model is proposed and illustrated using a female labour supply model estimated using cross section data the test statistic can be simply output from any standard tobit maximum likelihood package and is asymptotically efficient the procedure provides consistent estimators for the simultaneous tobit model whose asymptotic covariance matrix is a simple extension of the usual tobit formula we also provide the lagrange multiplier test of weak exogeneity this abstract was borrowed from another version of this item

the relative efficiency of public and private firms in a regulated environment the case of u s electric utilities abstract the relative efficiency of privately owned and publicly owned electric utilities is investigated using theoretical and econometric models that allow for the effects of both ownership type and regulation the estimation results indicate that the two types of firms are equally cost inefficient in the united states the average effect of inefficiency is to increase the cost of production by 2 4 percent holding output constant inefficiency increases the average quantities demanded of capital and labor and decreases the average quantity demanded of fuel
