some macroeconomic implications of alternative compensation systems a basic theme of this paper is the idea that some structural reform of employee compensation arrangements is necessary to make reasonable price stability compatible with reasonably full employment in this view even the best designed macroeconomic policies are much too aggregative to get at the heart of the stagflation problem the ultimate solution involves going inside the workings of a modern capitalist economy and correcting the underlying structural flaw directly on the level of the individual firm stagflation represents an especially intractable policy dilemma for macroeconomics without a decisive tendency of the economic system to remain near full employment there is a strong prima facie case for fighting recessions by exogenously stimulating aggregate demand but the usual keynesian expansionary policies tend to impart an inflationary inertia that is difficult to choke off and of course the basic strategy for fighting inflation is to cool down the economy by restrictive monetary and fiscal policy thereby increasing unemployment and closing the viscous circle because the practical macroeconomic policies for dealing with unemployment and inflation are so diametrically opposed stagflation is a pervasive structural problem when for whatever reason there is basically an unfavourable short run tradeoff between unemployment and inflation economic policy tends to vacillate between expansion of demand to fight unemployment and restriction of demand to fight inflation polarising the electorate and distracting society from dealing effectively with its underlying real economic problems even the difficulty of attaining external balance in foreign accounts is largely a spillover into the international payments arena of an inability to achieve an acceptable internal balance between full employment and price stability this paper takes what might be called a comparative systems approach to the problem of stagflation at the heart of modern industrial capitalism is an incredibly complicated system of overlapping monopolistic competitors 2 a starting point for the paper is the realisation that the coordination difficulty which can cause some systems to suffer involuntary unemployment is not inherent in laissez faire private enterprise per se it is closely tied to one particular property of a conventional wage payment system namely compensation of each firm s employees is stuck to an outside numeraire whether money or a cost of

efficient and durable decision rules with incomplete information we compare six concepts of efficiency for economies with incomplete information depending on the stage at which individuals welfare is evaluated and on whether incentive constraints are recognized an example is shown in which an incentive efficient decision rule may be unanimously rejected by the individuals in the economy we define durable decision rules which can resist such unanimous rejection and show that efficient durable decision rules exist

involuntary unemployment in economies with efficient risk sharing abstract we study economies where employment lotteries determine random layoffs and incomes for employed and unemployed agents allocate risk efficiently we ask for which specifications are unemployed agents worse off a situation we call involuntary unemployment we show unemployed agents are worse off iff an exogenous increase in wealth decreases aggregate unemployment in a monetary economy we show that in equilibrium the unemployed are worse off iff high inflation implies high unemployment our model also generates nominal wage stickiness as an equilibrium phenomenon but neither involuntary unemployment nor nominal stickiness implies these economies are operating inefficiently or are out of equilibrium

the effects of welfare and tax reform the material well being of single mothers in the 1980s and 1990s abstract the tax and welfare programs that provide income and in kind benefits to single mothers have changed dramatically in recent years these changes began as far back as the mid 1980s and culminated with the 1996 welfare law that ended welfare as we knew it these tax and welfare changes have sharply increased the employment of single mothers and cut welfare rolls however little is know about the effects of these policy changes on the material well being of single mothers and their children studies of those leaving welfare have found that a substantial percentage have problems paying rent purchasing enough food and paying utility bills other studies found a decline in income among the worst off single mothers after 1994 or 1995 the goal of this paper is to examine the material well being of single mothers and their families before and after recent welfare and tax reforms using data from two nationally representative household surveys we examine the consumption patterns of single mothers and their families from 1984 2000 we find that the material conditions of single mothers did not decline in recent years either in absolute terms or relative to single childless women or married mothers this pattern holds for the average single mother as well as for low educated single mothers at both the 15th and 25th percentiles of the consumption distribution in most cases our evidence suggests that the material conditions of single mothers have improved slightly

on success and dissolution of the labor managed firm in the capitalist economy labor managed firms lmfs in the developed capitalist economy exhibit an interesting life cycle pattern often they come into existence as a way of reorganizing insolvent entrepreneurial profit maximizing firms yet successful lmfs tend to be assimilated to the entrepreneurial modus operandi in the long run i propose a simple theoretical model that explains this lmf phenomenon as the outcome of the lmf s interaction with outside markets especially competitive spot labor markets the interpretations and limitations of the model are also discussed as the basic framework is extended to deal with imperfections in capital markets and with contractual labor markets

implicit contracts moral hazard and unemployment this paper considers a firm whose marginal revenue product of labor is a random variable we derive the form of an optimal long term contract between workers and the firm under the assumption that labor s marginal product is observed by the firm but not by the workers we show that the existence of asymmetric information causes unemployment to be greater than in a situation where information about labor s marginal product is public or where employment is determined in spot markets in particular unemployment can occur when the marginal product of labor exceeds the reservation wage

evaluating unemployment policies what do the underlying theories tell us the paper surveys unemployment policies for advanced market economies and evaluates them by examining the predictions of the underlying macroeconomic theories the basic idea is that for the most part different unemployment policy prescriptions rest on different macroeconomic theories and our confidence in the prescriptions should depend at least in part on theories ability to predict some salient stylized facts about unemployment behavior the paper considers four types of policies laissez faire demand management policies supply side policies and structural policies copyright 1995 by oxford university press

ranking alternative share contracts under rational expectations abstract this paper analyzes the price level and output stabilization properties of share contracts in a log linear rational expectations model profit sharing product wage and wage fund share contracts are compared to flexible and downwardly rigid nominal wage schemes we find that when the disturbances to the economy are nominal labor compensation schemes which reduce real variability exacerbate nominal variability when the disturbances are real compensation schemes which reduce real variability can also reduce nominal variability

equilibrium growth of the hierarchical firm shareholder employee cooperative game approach in recent years an implication of a classic paper by wassily leontief 1946 that is the possible inefficiency of the profit maximization principle within a certain bargaining framework has attracted the attention of economists faced with the increased possibility of such inefficiency due to the emergence of firm specific employment structures in large enterprises explorations into the possible modes of efficient and or equilibrium bargains over wage employment constellations have become a topic of recent research by economists most notably robert hall and david lilien 1979 and ian mcdonald and robert solow 1981 among others this paper investigates a similar and related problem supposing that the firm internalizes its own employment structure organized on the seniority principle is the value maximization rule for investment decision making efficient if it is not can we determine the proper rule for striking a balance between the time preference of the shareholder body and that of the employee body this problem will be dealt with in the framework of the cooperative game model of the firm as developed in my 1980 paper it will be shown that lower investment rationing of new jobs and higher pay rates are the consequences of a shift in the power balance within the firm in favor of the incumbent employees vis a vis the shareholder body this analysis will attempt to provide an integrated micro explanation of a widely observed macro phenomena in the 1970 s that is the negative relationship between the real wage and capital accumulation or between the real wage and employment see for example edmond malinvaud pentti kouri and jeffrey sachs the plan of the paper is as follows section i describes the model of the corporate firm internalizing employment structure hierarchically ordered upon the seniority principle section ii derives the coalitional equilibrium values of the endogenous variables of the model as a cooperative game solution it is shown that in the determination of the equilibrium growth rate of the firm gains from growth of the firm accruable to employees in the form of possible promotions must be taken into account to a degree determined by the power balance between the shareholders and the incumbent employees but under what types of institutional mechanisms can the time preference of employees be incorporated into the corporate policymaking section iii describes three highly stylized institutional models of shareholderemployee manager relationships with a view to their efficiency implications the appendix gives some technical results

internal bargaining and strategic innovation in the theory of the firm abstract the transaction cost analysis of the firm has identified asset idiosyncrasy and the risk of ex post opportunism as key determinants of organizational form simultaneously several writers have modeled the distribution of quasi rents among input suppliers as a bargaining game these complementary ideas are used to formalize the notion of strategic innovation where capital and labor attempt to redistribute firm income after specialized assets are in place through unilateral modifications in production technology because strategic behavior can enlarge the quasi rent component of fifirm income this process may persist in equilibrium asset idiosyncrasy therefore creates room for an autonomous theory of organizational dynamics partially insulated from events at the market level of analysis

bumping layoffs and worksharing this paper deals with an interesting but often neglected labor practice prevalent in large north american firms with well developed internal labor markets large north american firms typically respond to a decline in demand for their products by first reducing the number of hours worked or worksharing as the demand continues to fall however they begin to make skilled workers bump onto unskilled jobs displacing unskilled workers skilled workers are laid off only after a considerable number have bumped i develop an implicit contract model and explain the practice

unconditional cash transfers in china who benefits from the rural minimum living standard guarantee dibao program summary this paper analyzes china s rural minimum living standard guarantee dibao program one of the largest minimum income cash transfer schemes in the world and examines possible changes to the program design despite its size and central position in china s current poverty reduction strategy little is known about the rural dibao program s performance and targeting effectiveness our analysis uses annual household survey data from the china household income project matched with published administrative data for the years 2007 09 we find that the program provides sufficient income to poor beneficiaries but does not substantially reduce the overall level of poverty conventional targeting analysis reveals large inclusionary and exclusionary targeting errors propensity score targeting analysis yields smaller but still large targeting errors simulations of possible changes to the program design reveal that expanding coverage can potentially yield greater poverty reduction than increasing transfer amounts replacing locally diverse dibao lines and transfer amounts with a nationally uniform dibao threshold and transfer could in theory reduce poverty further but the potential gains are modest without improvements in targeting this paper makes several contributions to our knowledge this is the first household level empirical analysis of china s dibao program in rural areas so the findings provide new policy relevant information moreover the literature has not settled the question of whether such programs should be centralized or decentralized we show that in practice the potential gains of centralizing the eligibility rule and transfer amount are conditional on the efficiency of targeting by varying the program s key design parameters our analysis also yields insights into alternative policy recommendations to improve the program performance

distributional and efficiency impacts of increased us gasoline taxes we examine the impacts of increased us gasoline taxes in a model that links the markets for new used and scrapped vehicles and recognizes the consider able heterogeneity among households and cars household choice parameters derive from an estimation procedure that integrates individual choices for car ownership and miles traveled we find that each cent per gallon increase in the price of gasoline reduces the equilibrium gasoline consumption by about 0 2

does welfare enable family expenditures on human capital evidence from china summary using the national china household income project 2007 urban survey data and a propensity score matching method this article investigates whether welfare receipt helped enable low income families to spend more on human capital we find that welfare recipient families prioritized spending in health and education relative to their non recipient peers welfare particularly helped poor families afford medical care medicine tuition and fees for noncompulsory education private tutoring for children and purchasing of textbooks we find some evidence that welfare helped recipient families pay for maintenance fees for their residence but receiving welfare also deterred families from having leisure activities

large cash transfers to the elderly in south africa we examine the social pension in south africa where large cash sums about twice the median per capita income of african households are paid to people qualified by age but irrespective of previous contributions we present the history of the scheme and use a 1993 nationally representative survey to investigate the redistributive consequences of the transfers documenting who receive the pensions their levels of living and those of their families we also look at behavioural effects particularly the effects of the cash receipts on the allocation of income to food schooling transfers and savings in south africa a large social pension about twice the median per capita income of african households is paid in cash to people qualified by age irrespective of previous contributions we present the history of the scheme and explain how such large transfers could come about in an economy in which the recipients were not only politically weak but without any political representation whatsoever we then use a 1993 nationally representative survey to investigate the redistributive consequences of the transfers documenting who receive the pensions their levels of living and those of their families we also look at behavioural effects particularly the effects of the cash receipts on the allocation of income to food schooling transfers and savings the pressing policy issue for south africans is whether it makes sense to target seven billion rand nearly 2 billion of social expenditure through the current pension schemes our analysis contributes to the discussion by documenting the redistributive and behavioural effects of the transfers we find that at least as far as immediate incidence is concerned and without allowance for behavioural effects the social pension is an effective tool of redistribution and that the households it reaches are predominantly poor because so many of the elderly among south africa s african population live with children the social pension is also effective in putting money into house

optimal labour contracts under asymmetric information an introduction the review of economic studies has instituted a new series of lectures to be given annually by a younger british economist at the association of university teachers of economics meetings the choice of lecturer is determined by a panel whose members are currently professors hahn mirrlees and nobay this paper is a revised version of the first lecture in the series it was presented at the aute meeting held at the university of surrey in april 1982 and was refereed in the usual way mak

does britain or the united states have the right gasoline tax this paper develops an analytical framework to assess the second best optimal level of gasoline taxation taking into account unpriced pollution congestion and accident externalities as well as interactions with the broader fiscal system we provide calculations of the optimal taxes for the us and the uk under a variety of parameter scenarios under our central parameter values the second best optimal gasoline tax is 1 01 gal for the us and 1 34 gal for the uk current tax rates are much lower than this in the us and higher in the uk the calculations are moderately sensitive to alternative parameter assumptions the congestion externality is the largest component in both nations revenue raising needs also play a significant role as do accident externalities and local air pollution potential welfare gains from reducing the current uk tax rate are estimated at nearly one fourth the production cost of all gasoline used in the uk even larger gains could be achieved by switching to a tax on vehicle miles with equal revenue yield for the us the welfare gains from optimizing the gasoline tax are smaller but those from switching to an optimal tax on vehicle miles are very large

common pool equities an arbitrage based non cooperative solution to the common pool resource problem abstract it is proposed that a new type of property right termed a common pool equity can solve the common pool resource problem this equity may be presented to any firm that extracts from the resource for a share in profits it is shown that a profit arbitrage condition ensures that the market and socially efficient solutions correspond whenever market power is absent the cost externalities are fully internalized

how does public assistance affect family expenditures the case of urban china summary using recent national household survey data and a propensity score matching method this study examines the effects of urban china s primary public assistance program minimum living standard assistance mlsa on family expenditures an important yet understudied indicator of family material well being we find that families receiving mlsa prioritized human capital investment i e paying for education and health rather than making the ends meet e g paying for food clothing rent and utilities the policy implications of these findings are discussed

unemployment insurance and short time compensation the effects on layoffs hours per worker and wages we analyze two unemployment insurance systems in one unemployed workers receive benefits while those on reduced hours do not as in north america at least until recently in the other short time compensation is paid to workers on reduced hours as in europe the first system causes inefficient temporary layoffs for some parameters the latter does not but implies inefficient hours per worker some evidence is presented regarding these effects despite policymakers recent enthusiasm for short time compensation the clear implication of this project is that changes should come on the tax not benefit side of the system

welfare grants and their impact on child health the case of sri lanka summary this paper asks whether an exogenous increase in income in the context of a poverty alleviation program has an impact on child anthropometric outcomes the study looks at the samurdhi program in sri lanka and uses household data for 1999 2000 using propensity score matching to account for selectivity bias the paper finds that samurdhi improves the height for age z score of a child from a grant receiving family by roughly 0 40 standard deviations with the impact driven mainly by children between six and 36 months of age compared to if they did not receive the grant it also improves weight for height z scores by around 0 45 standard deviations of children aged 36 60 months these results are important for sri lanka where child nutrition is a cause for concern

optimal firm size taxes and unemployment abstract we analyze a model similar to the standard implicit contracting framework but assume that the size of the firm the number of workers under contract is endogenous some well known predictions from contract theory with firm size fixed exogenously are reversed in particular a result obtained by feldstein concerning unemployment insurance does not hold when firm size is chosen optimally he concludes an increase in experience rating the extent to which firms pay for unemployment benefits through their taxes reduces unemployment while we show that it increases unemployment under reasonable conditions

measuring the well being of the poor using income and consumption we examine the relative merits of consumption and income as measures of the material well being of the poor consumption offers several advantages over income because consumption is a more direct measure of well being than income and is less subject to underreporting bias measurement problems with income are problematic for analyses of changes in well being of the poor because the biases appear to have changed over time and are correlated with government policies on the other hand income is often easier to report and is available for much larger samples providing greater power to test hypotheses we begin by considering the conceptual and pragmatic reasons why consumption might be better or worse than income then we employ several empirical strategies to examine the quality of income and consumption data first we compare income and consumption reports for those with few resources as well as their assets and liabilities to examine measurement errors and under reporting second we examine other evidence on the internal consistency of reports of low income or consumption third we compare how well micro data in standard datasets weight up to match aggregates for classes of income and consumption that are especially important for low resource families fourth we validate income and consumption measures by comparing them to other measures of hardship or material well being although the evidence tends to favor consumption measures our analyses suggest that both measures should be used to assess the material well being of the poor

demand and supply side determinants of conditional cash transfer program effectiveness summary the programa nacional de becas estudiantiles is a conditional cash transfer program designed to promote human capital accumulation and reduce poverty among argentine youth this study follows a 1999 cohort of students for five years and uses matching methods with a comparison group of students excluded due to quotas to estimate average and marginal program impacts multilevel methods are used to explore the role of program management and execution in explaining variation between schools in student outcomes the results suggest that the becas program improved students attendance and performance in part through program conditions requiring good attendance and academic progress for continued scholarship receipt

the cost of reducing gasoline consumption high nominal gas prices new awareness of threats to national security and growing concern about global warming have reignited discussion of ways to reduce gasoline consumption in the united states debate centers on changing two policies already in place the federal gas tax and corporate average fuel economy cafe standards two influential recent reports find that increasing the gas tax would attain a given reduction in gas consumption at lower cost than would tightening cafe standards national research council 2002 congressional budget office 2003 the gas tax has this advantage because it encourages not just increases in fuel efficiency but also reductions in miles driven in contrast cafe standards actually encourage more driving because increases in fuel efficiency reduce the cost of gas per mile driven we also compare the costs of the gas tax and cafe standard but take into account interactions with preexisting tax distortions many papers examine the effects of these tax interactions in other contexts but to our knowledge none of them considers the cafe standard see e g lars bovenberg and ruud de mooij 1994 ian parry 1995 lawrence goulder 1995 bovenberg and goulder 1996 parry et al 1999 don fullerton and gilbert metcalf 2001 these interactions reduce the cost of the gas tax but increase the cost of cafe thus expanding the cost advantage enjoyed by the gas tax this difference does not arise because the gas tax raises revenue while the cafe standard does not rather this result is similar to that in west and williams 2004a which showed that since gasoline and leisure are relative complements raising the gas tax will increase labor supply generating additional efficiency gains in this paper we estimate a consumer demand system using data from the consumer expenditure survey and the california air resources board and find that miles driven and leisure are relative complements thus the gas tax encourages labor supply by raising the cost per mile driven producing an additional efficiency gain conversely because cafe reduces the cost per mile it discourages labor supply and yields an additional efficiency loss while the induced changes in labor supply are tiny relative to the labor market they are still substantial relative to the gas market and thus have a dramatic effect on the relative costs of the two policies our point estimates imply that they reduce the social marginal cost of the gas tax starting from the status quo gas tax rate and ignoring the benefits of reduced gas consumption by almost 30 percent while increasing the marginal cost of cafe by nearly 60 percent this result implies that the case for raising the gas tax rather than tightening the cafe standard is far stronger than previous studies suggest indeed it strongly suggests that any tightening at all of the cafe standard would lower welfare unless the benefits of reduced gas consumption have been seriously underestimated

internal bargaining labor contracts and a marshallian theory of the firm the theme of this paper is due to alfred marshall who states that nearly the whole income of a business may be regarded as a composite quasi rent divisible among different persons in the business by bargaining supplemented by custom and by notion of fairness and the division of quasi rents entails de facto some sort of profit loss sharing between almost every business and its employees principles of economics 8th ed book vi ch viii sec 10 pp 520 21 marshall emphasizes that a significant portion of composite quasi rent is derived from the organization of business and would be lost if employer employee connections were dissolved in this view bargaining can even be tacit insofar as there is an organizational basis which ensures agreement among the concerned parties consequently internal bargaining models of the firm may be applicable to the analysis of european style codetermination and japanese style labor management also as the relative bargaining strength between labor and management changes such a view of the firm admits as its extrema the organization of a labor managed firm lmf and the textbook case of a profit maximizing firm pmf masahiko aoki 1980 1982 and jan svejnar 1982 have recently explored models of an internal bargaining firm their analyses however consider the firm s long run behavior only under restricted circumstances without market uncertainty the relevance of the internal bargaining approach to profit sharing and labor management would be enhanced if we integrated the firm s short run wage employment policies with its long run plans for the rate of growth and capital labor substitutions this i do by underscoring the firm s organizational basis which is essentially a long term contractual association between workers and management i combine costas azariadis 1975 and martin baily s 1974 apparatus of labor contracting with efficient bargaining to investigate the effect of varying degrees of labor s bargaining power upon the firm s shortand long run policies under uncertainty these results are then contrasted with the empirical findings of collective bargaining for example richard freeman and james medoff 1981 conventional results of lmf models jaroslav vanek 1970 benjamin ward 1958 and the recent macroeconomic approaches to wage employment adjustments ian mcdonald and robert solow 1981

alternative approaches to evaluation in empirical microeconomics four alternative but related approaches to empirical evaluation of policy interventions are studied social experiments natural experiments matching methods and instrumental variables in each case the necessary assumptions and the data requirements are considered for estimation of a number of key parameters of interest these key parameters include the average treatment effect the treatment on the treated and the local average treatment effect some issues of implementation and interpretation are discussed drawing on the labour market programme evaluation literature

management versus ownership ii two fields in economics have developed without much interaction in the past the theory of the firm and mathematical economics the former has accumulated a wealth of thoughts observations on the firm activities without analytical scrutiny the latter has raised the standard of analytical rigor only within simple frameworks which do not fit the nature of the firm activities in the preceding paper ichiishi 1982 a mathematical model of a capitalistic economy was constructed and a rigorous analysis was given to the model this paper presents the economic interpretations implications of the formal study in ichiishi 1982 and shows how the gap between the two fields is bridged it is also intended to serve as a survey article

strategic investment and the co existence of labour managed and profit maximising firms the authors examine firm profitability in mixed duopoly equilibrium with one labor managed lm firm and one profit maximizing pm firm and with strategic investment conventional wisdom suggests that firms deviating from profit maximization will suffer forced exit in the long run the authors reverse this conclusion in mixed lm pm duopoly with strategic investment no equilibrium can have both firms making zero profits and pm profitability implies lm profitability but not the converse adverse parameter shifts would cause the pm firm to exit first empirical evidence is consistent with this prediction of robust market survivability of lm firms

models of modern sector labor market institutions in developing countries abstract the paper argues that policy conclusions derived from existing theories of economic development may be seriously flawed because the theories do not model correctly the modern sector labor market the paper first presents evidence that trade unions and governments frequently exert positive influence not only on firms wages but also on their employment levels it then presents models that capture this phenomenon and permit one to determine whether the observed levels of employment are insufficient optimal or excessive from the private and social standpoints the paper concludes with a discussion of how the analysis could be implemented in empirical studies and in practical policy work

nominal disturbances wage flexibility and shifting resources in a two sector economy the recent behaviour of european unemployment rates has sparked considerable interest in the connection between wage flexibility and unemployment see for example bruno and sachs i985 and the papers in the i986 supplement to economica much of the empirical work finds that economies adjust more rapidly and with less inflation when wages and prices are very responsive to unemployment this finding supports the belief that greater wage and price flexibility leads to greater macroeconomic stability in fact one can view martin weitzman s i 983 i 984 and i 985 share system as an institutional change aimed at providing sufficient wage and price flexibility to avoid unemployment it is hard to imagine how wage and price flexibility could increase in all sectors of the economy simultaneously instead greater aggregate wage and price flexibility is likely to result from increased wage and price flexibility at particular firms in particular sectors as a result realistic proposals for share systems involve some time perhaps forever when share firms and wage firms would coexist during this period an increase in aggregate flexibility will be associated with an increase in the difference in wage and price flexibility between sectors this paper analyses allocational issues raised by such an uneven increase in aggregate wage and price flexibility the analysis is done explicitly in terms of a short run two sector model where the first sector is a fixed wage sector and the second sector is a share sector the model is short run because both the number of firms in each sector and the pay parameters at all firms are fixed while the explicit analysis is done in terms of share firms in the second sector the model is more general the second sector can be thought of as the flexible sector where wage and price flexibility maintain full employment an important new phenomenon occurs in the mixed system relative prices change in response to nominal disturbances in particular the relative price of the flexible sector falls in response to a decrease in nominal aggregate demand as a result of the change in relative prices both the utilisation of labour and the mix of consumption shift to the more flexible sector in addition the opposite shifting of resources and consumption occurs in response to an increase

labor management bargaining contract curves and slutsky equations consider a firm in which labor and management bargain over division of the firm s organizational rent and negotiate the firm s policy i emphasize the relationship between the bargainer s contract curve and the firm s slutsky equations i can describe a bargaining firm as a hybrid of a neoclassical profit maximizing firm and a pure labor managed firm i apply the methodology to models of employment contracts and identify three separate circumstances in which labor s bargaining power affects the firm s comparative static behavior first there is inefficiency in contractual bargaining second income effects in the worker s utility function interact with the firm s capital cost burden third labor s interest in long term utility maximization need not coincide with management s interest in profit maximization this last case arises from the incompleteness of the market for property rights in the firm

capital labor and the firm a study of german codetermination under the german corporate governance system of codetermination employees are legally allocated control rights over corporate assets through seats on the supervisory board that is the board of nonexecutive directors the supervisory board oversees the management board the board of executive directors approves or rejects its decisions and appoints its members and sets their salaries we empirically investigate the implications of this sort of labor participation in corporate decision making we find that companies with equal representation of employees and shareholders on the supervisory board trade at a 31 stock market discount as compared with companies where employee representatives fill only one third of the supervisory board seats we show that under equal representation management board compensation provides incentives that are not conducive to furthering shareholders interests possibly because labor maximizes a different objective function than shareholders we document that under equal representation companies have longer payrolls than their one third representation peers have finally we provide evidence that shareholders respond to the allocation of control rights to labor by linking supervisory board compensation to firm performance and by leveraging up the firm jel g32 g34

customer markets trade unions and stagflation customer market analysis combined with trade union wage setting is shown to yield a range of equilibrium levels of employment only when employment is forced outside this range can the disequilibrium acceleration or d eceleration of the price level be expected to operate numerical calc ulations suggest that this range is quite large implying that the ma ximum level of unemployment consistent with nondecelerating inflation is way above the minimum level of unemployment consistent with nonac celerating inflation a range of equilibrium employment levels appear s to be in closer agreement with empirical experience than a unique natural rate of unemployment copyright 1987 by the review of economic studies limited

comparative economic performance of conventional and profit sharing firms abstract this paper compares the various economic properties of conventional firms and profit sharing firms the properties contrasted include wage level employment output price total economic rents and industry efficiency the firms operate in an oligopolistic industry with a labor union in general profit sharing firms outperform non sharing firms however there exist counterexamples in which non sharing firms can outperform sharing firms to test the robustness of the results the analysis is conducted for a variety of oligopolistic industries quantity setting pricesetting and joint collusion

estimating the benefit incidence of an antipoverty program by propensity score matching this brief summarizes the results of a gender impact evaluation study entitled estimating the benefit incidence of an antipoverty program by propensity score matching conducted between 1997 and 1998 in argentina the study observed that the average direct gain to the participant is found to be about half the gross wage over half of the beneficiaries are in the poorest decile nationally and 80 percent are in the poorest quintile the propensity score matching psm estimator is reasonably robust to a number of changes in methodology participants are more likely to be poor than non participants participants are less well educated live in poorer neighborhoods and are more likely to be members of neighborhood associations and political parties average gains are similar between men and women but are higher for younger workers funding for the study derives from the world bank research committee

lose some save some obesity automobile demand and gasoline consumption abstract this paper examines the unexplored link between the prevalence of overweight and obesity and vehicle demand in the united states exploring annual sales data of new passenger vehicles at the model level in 48 u s counties from 1999 to 2005 we find that new vehicles demanded by consumers are less fuel efficient on average as a larger share of people become overweight or obese the ols results show that a 10 percentage point increase in obesity and overweight reduces the average mpg of new vehicles demanded by 1 4 percent an effect requiring a 12 cent increase in gasoline prices to counteract the 2sls results after controlling for possible endogeneity in overweight and obesity prevalence put those two numbers at 5 percent and 54 cent respectively these findings robust to a variety of specifications suggest that policies to reduce overweight and obesity can have additional benefits for energy security and the environment

a silver lining the connection between gasoline prices and obesity i find evidence of a negative association between gasoline prices and body weight using a fixed effects model with several robustness checks i also show that increases in gas prices are associated with additional walking and a reduction in the frequency with which people eat at restaurants explaining their effect on weight my estimates imply that 8 of the rise in obesity between 1979 and 2004 can be attributed to the concurrent drop in real gas prices and that a permanent 1 increase in gasoline prices would reduce overweight and obesity in the united states by 7 and 10

on weitzman s recession resistant employee compensation arrangements abstract this note presents a slight modification of the alternative pay systems discussed by weitzman 1983 the modification preserves the recession resistance property yet guarantees that the workers already in the firm will not become worse off by the conversion to the new pay system even when no other firm converts to it

automobile externalities and policies this paper discusses the nature and magnitude of externalities associated with automobile use including local and global pollution oil dependence traffic congestion and traffic accidents it then discusses current federal policies affecting these externalities including fuel taxes fuel economy and emissions standards and alternative fuel policies summarizing insofar as possible the welfare effects of those policies finally we discuss emerging pricing policies including congestion tolls and insurance reform and summarize the appropriate combination of policies to address automobile externalities

increasing returns and the foundations of unemployment theory current approaches to macroeconomic theory divide roughly into two basic schools of thought one approach typically associated with rational expectations views the economy as basically at or near walrasian market clearing equilibrium in which case it becomes very difficult to explain away convincingly the undeniable persistence at times of involuntary unemployment another approach views the underemployed economy as being in a state of temporary fixed price disequilibrium in which case aside from having to repress suspicions that the essence of effective demand failure might not have to do with prices fixed at wrong values there is a lot of rationalising to be done about why profitable adjustments are so slow this paper argues that something like an internally consistent theory of steady state involuntary unemployment is possible and even plausible the cornerstone of this third approach is increasing returns to scale which blocks unemployed agents from breaking out of a low level equilibrium trap unless there is overall coordination or stimulation a simple model is presented which contains the basic ideas

the empirical performance of orthodox models of the firm conventional firms and worker cooperatives though it is routinely posited that organizations with different property rights will not exhibit the same responses to changes in their economic environment compelling evidence of such behavior is difficult to find we collected observations on two types of firms conventional proprietorships and worker owned cooperatives operating in the same industry in the same location and at the same period of time we compare the firms reactions to changes in their input and output prices and ask whether their reactions are consistent with orthodox models of profit and dividend maximization

equilibrium long term labor contracts the paper presents a labor market equilibrium analysis of implicit contract theory a two period single good model is used to propose consistent notions of labor market equilibrium for long term employment contracts both when labor is specialized and cannot move in the second period and when there is free mobility without costs the result that long term contracts emerge in equilibrium even without mobility costs is novel and contrary to common beliefs the main features of equilibrium are that risk neutral firms will insure risk averse workers against downside risk yielding downward rigid wages wages are not fully rigid as in earlier work on contract theory because workers may quit and wages have to be bid up to retain them the firm gets its return of the insurance deal by paying less than marginal product in the first period the resulting equilibrium is second best and lies between productive efficiency and full insurance workers gain from long term contracts in comparison to spot markets whereas owners may not in the model with specialized skills there exist transfer payments such that both parties are better off within an equilibrium with long term contracts

the theory of the labour managed firm revisited the voluntary interactive approach membership in the authors labor managed firm is determined in the long run by expected income maximization in the short run upon the realization of output price each member may leave the labor managed firm however a decision to leave when the entire membership quits is associated with fixed cost this arrangement ensures ex post egalitarianism and sense of job security the authors short run result is that employment does not exhibit a perverse response to price variations the long run result is that their labor managed firm is more populous than the illyrian firm and may even be more than its capitalistic twin copyright 1993 by royal economic society

profit sharing risk sharing and firm size implications of efficiency wages by taking account of output fluctuations this paper constructs a synthesis of profit sharing and efficiency wage models to highlight the role of the risk attitudes of the firm and its employees we show contrary to the traditional efficiency wage theory that in a profit sharing economy unemployment is no longer a necessary device to induce work effort and consequently the labor market equilibrium may be characterized by full employment such a result is more likely to be true when the economy is characterized by small sized firms in addition we also provide a preliminary sketch of the situations in which the firm chooses a profit sharing program or a fixed wage one and discuss how a firm determines its pay parameters and employment in response to output fluctuations

distributional effects of alternative vehicle pollution control policies abstract previous work shows that policies that subsidize new vehicles and tax size miles or gasoline efficiently reduce pollution less is known about their distributional effects this paper examines distributional effects by estimating the joint demand for vehicles and miles using the consumer expenditure survey greater price responsiveness among low income households enhances progressivity of gas or miles taxes across lower incomes and mitigates regressivity across upper incomes taxes on engine size or subsidies to new vehicles are significantly more regressive than gas or miles taxes
