restructuring enterprises in eastern europe eastern europe s enterprises are undergoing fundamental reform this paper evaluates alternative forms of corporate restructuring emphasizing different sequences in which reforms can be organized in some countries restructuring is undertaken by the state prior to privatization in some restructuring is delegated to private sector institutions before shares are offered to the public at large and in some public share offerings are preceding restructuring the paper develops a general framework for evaluating sequencing drawing on recent literature on corporate ownership and vertical integration it points to market failures that are particularly acute during the initial stages of transition these discourage privatization through wide share ownership and explain why privatization has in practice progressed slowly the paper examines in some detail restructuring in the one country in which reform has been rapid east germany the paper discusses the role of the government the treuhandanstalt the banks the incumbent management and western firms in the reform process it uses the theoretical framework to explain the contributions of public and private sector institutions and considers whether any lessons can be drawn for the design of institutions elsewhere

cooperative and noncooperative r d in duopoly with spillovers contrary to the usual assumption made in most oligopoly models relations among firms are seldom of a wholly cooperative or noncooperative type in many situations they compete in some fields while they cooperate in others an important example is the case of cooperative research efforts bringing fierce competitors together two types of agreement are observed first r d cooperation can take place at the so called precompetitive stage companies share basic information and efforts in the r d stage but remain rivals in the market place 1 a second type of agreement involves an extended collusion between partners creating common policies at the product level the usual justifications of this extension are the difficulties of protecting intellectual property the idea is then to allow partners who have achieved inventions together to also control together the processes and products which embody the results of their collaboration in order to recuperate jointly their r d investments 2 what could be expected from these types of agreement is a reduction in r d expenditures because of less wasteful duplication and a reduction of total production because of more reprinted from the american economic review 78 5 1133 1137 1988 center for operations research econometrics 1348 louvain la neuve belgium we are grateful to jean

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

does privatization remove restrictive working practices evidence from uk establishments this study investigates the links between privatization and changes in working practices using data from the uk 1990 workplace employees relations survey privatization raises the probability of an establishment of experiencing reduced job demarcation and or increased flexibility in the use of the workforce by managers after exploration no clear association is found between ownership and the level of restrictive working practices

a test for moral hazard in the labor market contractual arrangements effort and health moral hazard plays a central role in many models depicting contractual relationships involving worker effort the authors show how time series information on worker health consumption and work time can be used to measure the effort effects of payment schemes estimates from longitudinal data describing farming rural households indicate that time wage payment schemes and share tenancy contracts reduce effort compared to piece rate payment schemes and on farm employment the evidence also indicates consistent with moral hazard that the same workers consume more calories under a piece rate payment scheme or in on farm employment than when employed for time wages copyright 1994 by mit press

incentives and the efficiency of public sector outsourcing contracts abstract outsourcing the provision of traditionally publicly provided services has become commonplace in most industrialized nations despite its prevalence there still is no consensus in the academic literature on the magnitude and determinants of expected cost savings to the government nor the sources of those savings this article considers the arguments for and against outsourcing and then examines the empirical evidence pertaining to whether any observed savings occur and whether they persist over time in addition we examine the existing evidence for the redistribution hypothesis and the quality shading hypothesis which critics have used to argue that outsourcing lowers government expenditure by lowering wages and conditions and or lower quality services finally we consider the impact of contract design on outsourcing outcomes while the power of incentives is a strong theme in economics recent work has suggested that high powered incentives may be suboptimal for many public sector services because they may crowd out intrinsic motivation particularly in instances where agents are highly motivated we discuss the implications of this insight for the efficiency of public sector outsourcing

endogenous structures of association in oligopolies the formulation of associations of firms in an oligopoly with linear demand is analyzed as a two stage noncooperative game in the first stage firms form associations in order to decrease their costs and in the second stage they compete on the market examples of associations include r d joint ventures and groups of firms adopting common standards in equilibrium the associations formed exhibit two general features they are asymmetric and inefficient

agricultural household models extensions applications and policy this book presents the basic model of an agricultural household that underlies most of the case studies undertaken so far the model assumes that households are price takers and is therefore recursive the decisions modeled include those affecting production and the demand for inputs and those affecting consumption and the supply of labor comparative results on selected elasticities are presented for a number of economies the empirical significance of the approach is demonstrated in a comparison of models that treat production and consumption decisions separately and those in which the decisionmaking process is recursive the book summarizes the implications of agricultural pricing policy for the welfare of farm households marketed surplus the demand for nonagricultural goods and services the rural labor market budget revenues and foreign exchange earnings in addition it is shown that the basic model can be extended in order to explore the effects of government policy on crop composition nutritional status health saving and investment and to provide a more comprehensive analysis of the effects on budget revenues and foreign exchange earnings methodological topics primarily the data requirements of the basic model and its extensions along with aggregation market interaction uncertainty and market imperfections are discussed the most important methodological issues the question of the recursive property of these models is also discussed

the effect of child labor on learning achievement abstract this paper analyzes the effect of children s work on learning achievement its particular significance is that it goes beyond the analysis of the effects on school enrollment or attendance by using measures of skills learned in reading and mathematics the results show that work outside the household has a substantial effect on learning achievement although they confirm the accepted wisdom they introduce a new view of how that arises a large part of it is direct and not through school attendance the direct link could exist because of exhaustion or because of a diversion of interest away from academic concerns

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

the role of information sharing in cooperative research and development abstract this paper develops a model in which r d cooperation enables firms to increase the probability of discovering a new product by sharing information about research strategies and outcomes numerical computations of equilibrium show that cooperation tends to increase in the underlying probability of research success total surplus generally increases as more firms cooperate and cooperation in equilibrium never exceeds that which maximizes total surplus however when the probability of an innovation s success is relatively low no cooperation occurs nor will much be socially desired finally self imposed limits on membership in the cooperative entity tend to reduce total surplus

pay and employment determination in britain what are labour contracts really like the recent growth of unemployment in western economies has prompted new research on the workings of the labour market there has been much interest in particular in the questions what determines the level of real pay and why is it apparently so insensitive to changes in aggregate demand and unemployment european economists now find it hard to take seriously the notion still taught to many undergraduate that wages are determined by the intersection of demand and supply curves roughly half of all british employees belong to trade unions a much higher percentage have their pay fixed by some kind of collective bargain in this country it is negotiations not impersonal com petitive markets which decide what most of us will be paid the difficult problem is that of how to understand this process or to put it differently of how to think up the right model of the world

nash bargained household decisions reply pierre andre chiappori s 1988 claim that the nash bargaining model is of weak empirical relevance and neither convenient nor really restrictive is incorrect nash bargained household behavior implies a rich set of empirical implications extending well beyond the pareto efficiency of intrafamily distributions by systematically accounting for the impact of opportunities outside the family on resource distribution within the family nash bargained demand theory considerably expands the scope of neoclassical demand theory such expansion can elucidate issues ranging from the impact of alimony and child support laws in developed societies to the intrafamily distribution of nutrition in less developed countries copyright 1990 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

what has 20 years of public private pay gap literature told us eastern european transitioning vs developed economies this paper surveys the literature on public private sector pay differentials based on 20 years of research in transitioning countries of eastern europe ee and compares the results with estimates obtained from developed market economies the majority of empirical studies from ee economies found evidence of public sector pay penalties during the period of economic transition from a communist to market based economy in developed economies however the average differential is usually around zero or positive the public sector pay inequality reducing effect relative to the private sector is greater in transitioning economies than in developed economies nevertheless there is evidence that the sign of the public sector pay gap as well as the relative public sector pay distribution change with the progress of economic transition towards those usually observed in developed economies different pay setting arrangements between private and public sectors and competition for workers seem to be major arguments for the existence of systematic pay differences between the two sectors

productive efficiency in public and private firms abstract this paper compares the degree of x inefficiency which emerges as a consequence of the imposition of the optimal incentive contracts in public and private firms using a straightforward principal agent model with two possible states of the world it establishes the rather surprising result that in the good state of the world public ownership always results in a higher degree of productive efficiency

the effect of sibling sex composition on women s education and earnings this paper documents the impact of siblings on the education of men and women born in the united states between 1920 and 1965 we examine the effect of the number and sex composition of a boy or girl s siblings on that child s educational attainment we find that throughout the century women s educational choices have been systematically affected by the sex composition of her siblings and that men s choices have not women raised only with brothers have received on average significantly more education than women raised with any sisters controlling for household size since sibling sex composition affects women s educational attainment and plausibly may be unrelated to other determinants of earnings it may provide a useful instrument for education in earnings functions for women our results suggest that standard estimates significantly underestimate the return to schooling for women

work rules featherbedding and pareto optimal union management bargaining this article examines a model of semiefficient bargaining in which the union and the firm bargain over wages and various types of work rules the results are compared to the outcomes that are associated with fully efficient bargaining i e over wages and the level of employment and bargaining solely over wages

the role of competition for an x inefficiently organized firm abstract this paper presents a manager controlled firm which does not minimize long run costs even though the manager is the residual claimant maximizing a profit depending salary the inefficiency results because the employment contracts are not binding in the long run the manager is afraid of being replaced by a rival therefore he invests too much to strengthen his bargaining position in the contract renegotiation the inefficiency is reduced by competition in the output market

ownership versus competition efficiency in public enterprise certainly the introduction of product market competition into potentially competitive or at least contestable markets can improve performance to take just one example morrison and whinston 1986 1986 estimate that even in the imperfectly contestable u s airline industry the annual u s welfare gains from deregulation have been around 6 billion

the political economy of benefits and costs a neoclassical approach to distributive politics this essay offers a rational political explanation for the notorious inefficiency of pork barrel projects with an optimization model of legislative behavior and legislative institutions the model emphasizes the economically arbitrary from a welfare point of view importance of the geographic incidence of benefits and costs owing to the geographic basis for political representation we explore the implications of a legislator s objective function and derive conditions under which a representative legislature will select an omnibus of projects each of which exceeds the efficient scale

stakeholders relationships and product market competition abstractin this article we study the relationships between main stakeholders shareholders consumers and employees when firms are consumer oriented co in the sense of caring about consumers interests in the objective function we let these firms first bargain with labour union over their employees wages and then compete either in the quantity space cournot competition or in the price space bertrand competition our model shows that taking care of the consumers interests when determining product market strategies may reverse the traditional ranking between cournot and bertrand equilibria this implies that if shareholders in a co firm can choose either a quantity or a price strategy they will surprisingly choose the latter moreover we show that the conflicting interests between main stakeholders are attenuated under bertrand competition compared to cournot competition

child farm labor the wealth paradox this article is motivated by the remarkable observation that children of land rich households are often more likely to be in work than the children of land poor households the vast majority of working children in developing economies are in agricultural work predominantly on farms operated by their families land is the most important store of wealth in agrarian societies and it is typically distributed very unequally these facts challenge the common presumption that child labor emerges from the poorest households this article suggests that this apparent paradox can be explained by failures of the markets for labor and land credit market failure will tend to weaken the force of this paradox these effects are modeled and estimates obtained using survey data from rural pakistan and ghana the main result is that the wealth paradox persists for girls in both countries whereas for boys it disappears after conditioning on other covariates

intertemporal substitution in labor supply evidence from micro data the sensitivity of the supply of labor to intertemporal variation in the wage is an important issue in macroeconomics the analysis of social security and pensions and the study of life cycle patterns of work this paper explores two approaches to the measurement of intertemporal substitution that have appeared in the literature the first approach is to use consumption to control for wealth and unobserved expectations about future wages in the labor supply equation the second approach is to estimate a first difference equation for hours in which labor supply from the previous period serves as a control for wealth and wage expectations the results indicate that intertemporal substitution elasticity for married men is positive but small

gender agricultural production and the theory of the household virtually all models of the household assume that the allocation of resources is pareto efficient within many african households agricultural production occurs on many plots controlled by different members of the household pareto efficiency implies that factors should be allocated efficiently across these plots i find in contrast that plots controlled by women are farmed much less intensively than similar plots within the household controlled by men the estimates imply that about 6 percent of output is lost because of inefficient factor allocation within the household the paper suggests a new approach to modeling intrahousehold allocation consistent with the empirical results

household composition labor markets and labor demand testing for separation in agricultural household models this paper tests the separation of farm labor supply and labor demand decisions using the observation that household composition is an important determinant of farm labor use with nonseparation after assessing the conditions under which the test has power against several alternatives an empirical model is developed to test the proposition that farm employment is independent of family composition the model is estimated on a data set from rural java the null hypothesis that farm labor allocation decisions are independent of household structure is not rejected the results are robust to different specifications of the labor demand function copyright 1992 by the econometric society

do public ownership and lack of competition matter for wages and employment evidence from personnel records of a privatized firm do public sector firm ownership and lack of competition matter for wages and employment to address this question we consider a large public sector company that is privatized using personnel records we find employment contract liberalization to generate relative wage losses for older high tenure low skilled part time workers permanent residents and women employment reductions mostly affect the same groups experiencing a wage decline overall wage liberalization leads to an increase in wage inequality of between 6 and 9 which if applied to the whole public sector would lead to a 52 to 76 closure of the inequality gap between the private and public sectors in europe our results suggest that differences between public and private sector wage structures found in descriptive studies are to a large extent causal rather than the result of selection into these sectors and that public sector employment and career path regulations limit a firm s ability to maintain a competitive workforce

growth technological change and ict diffusion recent evidence from oecd countries in this paper we present an overview of gdp and productivity growth patterns in oecd countries over the past decade on the basis of harmonized data our evidence suggests that fast growing countries generally shared three characteristics improvements in labour utilization a generalized enhancement in human capital and rapid shifts in the composition of physical capital towards information and communication technology ict equipment particularly we show that technological change embodied in new ict capital goods has been a primary source of output and productivity growth in ict using sectors the international comparison allows relating growth patterns to institutional and policy indicators thereby offering some preliminary insights into the potential sources of growth disparities cross country evidence yields some tentative support to the idea that institutional factors affecting competition in the product market are likely to affect productivity patterns especially in a period of rapid diffusion of a general purpose technology such as ict copyright 2002 oxford university press

the relevance of standard estimates of rates of return to schooling for education policy a critical assessment abstract this paper examines the accuracy and usefulness of estimated rates of return to schooling based on the standard human capital model of becker and mincer regarding accuracy it investigates whether failure to account for differences in ability and school quality lead to significant biases estimates using ghanaian data confirm this possibility even when accurate estimated rates of return to additional years of schooling may have limited policy implications more useful for governments are rates of return to investments in school quality the paper uses data on cognitive skills to estimate rates of return to three types of school quality improvements

privatisation and x inefficiency a bargaining approach the usual analysis of privatization and x inefficiency uses agency theory to model managerial effort the authors model worker effort as determined by a bargain between firms and workers workers dislike effort because it lowers utility firms prefer high effort because it raises productivity public sector firms are assumed to be social welfare maximizers and therefore compared to private sector firms they bargain lower effort levels since they have the interests of consumers and workers at heart the authors model predicts that under certain conditions privatization should raise effort and so lower x inefficiency and that wages may increase or decrease copyright 1995 by blackwell publishing ltd

food for education versus school quality a comparison of policy options to reduce child labour in a model in which credit markets play a crucial role we examine two policy options for reducing child labour food for education and investment in education quality with an imperfectly elastic supply of credit an increase in food subsidy is more eective in reducing child labour than an income equivalent increase in expenditures in education quality the eectiveness of the latter policy improves and the optimal share of resources devoted to this policy increases at the expense of food subsidies as the supply of credit becomes more elastic

shadow wages and peasant family labour supply an econometric application to the peruvian sierra a striking feature of developing economies is the large proportion of the work force that is self employed lack of widespread labor market participation in the agricultural sector can pose a major obstacle to the empirical implementation of economic models of the peasant household whether because wage data are simply not available or because the assumptions required to make use of wage data stretch the bounds of credulity this paper develops a methodology for estimating a structural labor supply model for primarily self employed peasant households which holds under a general agricultural technology and set of labor market conditions the unique feature of the approach is that the opportunity cost of time or shadow wage of household workers is explicitly estimated from an agricultural production function and is subsequently used to identify a set of structural labor supply parameters recent household survey data from rural peru is employed to estimate and perform various diagnostic tests on the model the empirical findings lend support to the hypothesis that peasant households allocate their members time as if to maximize a family utility function and moreover demonstrate the tractability of the shadow wage methodology and its usefulness in estimating more elaborate time allocation models

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

a bargaining model of farrell inefficiency abstract an enormous number of empirical papers have estimated technical efficiency the distance of firms inside a frontier following the model of farrell farrell 1957 the measurement of productive efficiency journal of the royal statistical society series a 120 3 253 290 we propose a theory that explains the distance these empirical papers seek to measure the theory is based on the idea that workers can bargain low effort high crew sizes etc if they and the firm have some monopoly power we provide simple theoretical expressions for the empirical measures of technical and allocative efficiency and compare them to those in the statistical literature we also consider the relation between competition and efficiency

household income and child schooling in vietnam the stronger are the associations between household income and child schooling the lower is intergenerational social mobility and the less equal is opportunity this study estimates the associations between household income and children s school success in vietnam the estimates indicate that these associations are considerable this article also investigates some ways in which policies relate to household incomes school fees are progressive but school fees are only about one third of what households pay directly to schools and are a much smaller proportion of a household s total school related expenditures total household expenditures paid directly to schools increase with household income less proportionately than do school fees alone so the overall structure of such payments is less progressive than is the structure of school fees because school enrollment is positively related to household income moreover the structure of school fees is less progressive for the entire population than for the selected subset that has children enrolled in school further the two school quality measures that have the strongest positive association with children s school success are much more available to higher income households meaning that higher income households have greater school expenditures in part because they are obtaining higher quality schooling and not because charges for the same quality schooling are progressive across income classes

using propensity matching estimators to evaluate the impact of privatization on wages whether the transfer of ownership rights to the private sector leads to a decline or increase in wage growth is theoretically ambiguous given that the outcome depends on the uncertain interaction between firms and workers using propensity matching techniques this article investigates the effects of privatization on wages in the portuguese banking industry the empirical results obtained from quadros de pessoal for the period between 1989 and 1997 generally show a negative positive short run long run effect of privatization on relative wage growth for both men and women retained in the privatized firms moreover the results show that the most educated and experienced oldest workers as well as those in the high skill occupational categories were more likely to experience a negative wage effect

increasing the profits of a subset of firms in oligopoly models with strategic substitutes consider an industry composed of n firms in a symmetric equilibrium designate a subset of s n firms and marginally reduce the strategic variables of the firms in the subset if the remaining firms simultaneously make the best reply to this exogenous displacement under what circumstances will profits of the firms in the designated subset increase we show that in the case of cournot competition among producers of perfect substitutes a marginal contraction is strictly beneficial strictly harmful if and only if the number of firms in the designated subset exceeds the adjusted number of firms outside it by strictly more strictly less than one the adjustment factor is unity when cost and demand functions are linear but more generally depends on the convexity of the cost and demand curves thus a marginal contraction of two firms in a triopoly has no effect on the profits of firms in the subset if cost and demand functions are linear if instead cost is linear but the inverse demand function is strictly concave strictly convex a marginal contraction will strictly decrease strictly increase profits the analysis is extended to the effects of nonmarginal exogenous changes in the outputs of the constrained firms this extension has implications for the relationship of stackelberg sequential move and nash simultaneous move equilibria our analysis has broad application to illustrate we show that it unifies results in the literature on export subsidies horizontal mergers and strikes the paper is organized as follows in section i our comparative static result is derived in section ii we present a wide range of applications in the conclusion and the appendix we generalize our analysis to other situations involving strategic substitutes

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

strategic alliances as stackelberg cartels concept and equilibrium alliance structure abstract this paper analyzes incentives of oligopolistic firms to form strategic alliances and the effects of the endogenously derived alliance structure on product market competition a three stage game is considered in the first stage firms decide about forming strategic alliances in the second stage each alliance designs a strategic contract and in the third stage alliance members and outsiders compete in the product market it is shown how contractual terms about transfer prices and profit sharing in a production joint venture for an intermediate product may serve as an appropriate commitment device profits of alliance members and outsiders under different alliance structures are then determined based on this profit structure the alliance formation process is analyzed in a linear cournot oligopoly with at most five firms only one alliance forms and industry output is reduced with more than five firms an alliance structure with at least two alliances results if an equilibrium of the alliance formation game exists and in this case competition is enhanced
