bidding behavior in first price sealed bid auctions use of computerized nash competitors abstract results are reported from a series of first price sealed bid auctions where bidders face computerized nash equilibrium competitors the results provide strong support for employing this newly developed methodology as a testing procedure for nash equilibrium bidding models

the consequences of minimum wage laws some new theoretical ideas economists generally agree that the effect of a binding minimum wage law is to move firms backward along the demand curve for low skill workers however this prediction of worker displacement depends critically on the assumption that the productivity of firms labor is not dependent on the wage in this paper we show that in a conventional efficiency wage model a minimum wage may increase the level of employment in low wage jobs the formal logic of our model is similar to the case of labor demand under monopsony but arises in a model with a large number of employers

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

a multisector model of efficiency wages the pattern of effort and wages is derived in a multisector efficiency wage model firms choose effort endogenously easily monitored or low turnover jobs have high effort and may have low wages in equilibrium empirical wage differentials from a measure of supervision are smaller than observed industry differentials that have been attributed to efficiency wage models and are closer to those predicted by the model workers can search for and avail of on the job offers if sectors grow at different rates or the unemployment rate changes the pattern of wage differentials is unaffected

estimating the demand for a new technology bt cotton and insecticide policies this article examines the potential demand for bt cotton in the southeast from information gathered in the first year of commercialization we combine revealed preference rp data on adoption of bt cotton varieties with stated preference sp data on willingness to adopt to estimate demand using a double bounded maximum likelihood procedure using estimated demand equations we simulate the costs of reducing conventional insecticide applications through subsidization of bt cotton results indicate that reducing cotton insecticide applications by 40 in the southeast would require a 21 acre subsidy with total annual program costs between 53 million and 60 million

bubbles crashes and endogenous expectations in experimental spot asset markets1 spot asset trading is studied in an environment in which all investors receive the same dividend from a known probability distribution at the end of each of t 15 or 30 trading periods fourteen of twenty two experiments exhibit price bubbles followed by crashes relative to intrinsic dividend value when traders are experienced this reduces but does not eliminate the probability of a bubble the regression of changes in mean price on lagged excess bids number of bids minus the number of offers in the previous period p pt a f b 1 o l supports the hypothesis that a e d the one period expected value of the dividend and that f 0 where excess bids is a surrogate measure of excess demand arising from homegrown capital gains losses expectations thus when bt 1 o goes to zero we have convergence to rational expectations in the sense of fama 1970 that arbitrage becomes unprofitable the observed bubble phenomenon can also be interpreted as a form of temporary myopia tirole 1982 from which agents learn that capital gains expectations are only temporarily sustainable ultimately inducing common expectations or priors tirole 1982 four of twenty six experiments all using experienced subjects yield outcomes that appear to the chart s eye to converge early to rational expectations although even in these cases we get 0 and small price fluctuations of a few cents that invite scalping

do regulations work a comprehensive analysis of price limits and trading restrictions in experimental asset markets with deterministic and stochastic fundamental values abstract we examine how traders react to two prominent stock market regulations under a constant fundamental value fv process price limits and trading restrictions significantly reduce the price level and mispricing size when traders are inexperienced under a markov process fv there is no evidence for these regulations to reduce mispricing the novel markov process also serves as a testbed for several financial hypotheses related to the regulations we find that price limits do not improve reactions to market news and the binding of price limits magnifies the momentum in the price movements these findings suggest that the scope of these regulations is limited and that they can backfire in some market environments

the roles of the state and the market in establishing property rights it is an old saw of the economics profession that markets require a clear assignment of initial entitlements to most resources and well enforced rules of contract governments intent on fostering a market economy should thus make sure to put an effective legal system in place one in which property rights are unambiguous secure and freely alienable even if the state gets some of the initial entitlements wrong it is often added the coase theorem instructs us that the parties if free to contract will correct this by appropriate private agreements the experience of postcommunist countries in eastern europe is a good reminder that economists tend to assume a can opener when one is needed indeed the statement that property and contract rights must be put in place assumes away one of the most interesting and intricate questions concerning economic development the creation of a system of enforceable entitlements to the diverse and complex forms of wealth characteristic of a modern society is itself a process subject to economic laws as i shall argue here it is in fact largely a product of market forces rather than governmental fiat

on insider privatization privatization is proceeding slowly in many eastern european countries this is largely because the insiders who currently have control but not property rights to the firms oppose outsider privatization privatization would proceed faster if governments decided to go the insider privatization route there would seem to be two strong efficiency arguments for doing so first insider privatization aligns control and property rights this gives the right incentives to insiders second if for some reason insiders cannot do the job themselves they will have the right incentives to sell the firms to those outsiders who can our paper focuses on this second argument we conclude that it is not as obvious as it seems there is a wedge between the value of the firm to insiders and the value of the firm to outsiders depending on the details of insider privatization and on the details of the resale process this wedge may prevent resale and thus prevent desirable restructuring

a political economy approach to the neoclassical gradualist model of transition a political economy approach to the neoclassical gradualist model of transition requires the exposition of what i define the primary elements of the model which are economic analysis definition of a good society speed political structure ideological structure and whether the initial conditions were incorporated in the model after the identification of the primary elements of the neoclassical gradualist model the next step is to identify secondary elements the desired changes with respect to price liberalization stabilization privatization institutional structure monetary policy and the financial system fiscal policy international trade and foreign aid and social policy the analytical framework developed makes possible to understand the neoclassical gradualist model from a new and more enlightening perspective we are better able to comprehend the complexities involved and the disagreements about the reform process the adoption of a gradual process of transition did not only involve specifying the required policies of a successful transition but also entailed a process a sequence by which the reforms should be introduced as such a process of transition consistent with the policies recommended by the neoclassical gradualists economists is developed the conclusion reveals the inconsistencies in the model copyright blackwell publishers ltd 2005

the bubble game an experimental study of speculation we propose a bubble game that involves sequential trading of an asset commonly known to be valueless because no trader is ever sure to be last in the market sequence the game allows for a bubble at the nash equilibrium when there is no cap on the maximum price we run experiments both with and without a price cap structural estimation of behavioral game theory models suggests that quantal responses and analogy based expectations are important drivers of speculation

classroom games speculation and bubbles in an asset market this paper describes a classroom exercise in which students trade assets of uncertain value in a sequence of market periods assets pay one dollar dividends at the end of each period but once the dividend is paid there is fixed probability that the asset will be destroyed dividends and probabilities are chosen so that the fundamental value is constant over time speculative bubbles can be caused by divergent expectations about other traders valuations of the asset this exercise provides an interactive framework that facilitates discussions of discounting rational expectations and backward induction

the chinese warrants bubble in 2005 2008 over a dozen put warrants traded in china went so deep out of the money that they were almost certain to expire worthless nonetheless each warrant was traded more than three times each day at substantially inflated prices this bubble is unique in that the underlying stock prices make warrant fundamentals publicly observable and that warrants have predetermined finite maturities this sample allows us to examine a set of bubble theories in particular our analysis highlights the joint effects of short sales constraints and heterogeneous beliefs in driving bubbles and confirms several key findings of the experimental bubble literature jel g12 g13 o16 p34

unemployment and product market competition in a cournot model with efficiency wages this paper analyzes the impact of product market competition on unemployment wage and welfare in a model where unemployment is caused by the efficiency wage consideration and oligopolistic firms compete in quantity it is shown that while more intense competition in the product market increases output and reduces price it does not necessarily lead to a lower unemployment rate or a higher wage for workers depending on the technologies the relationship between the intensity of competition and the level of employment respectively wage welfare is not always monotonic and in some instances has an inverted u shape resume chomage et concurrence dans le marche du produit dans un modele a la cournot en presence de salaires d efficience ce texte analyse l impact de la concurrence dans le marche du produit sur le chomage le salaire et bien etre dans un modele ou le chomage est cause par des considerations de salaires d efficience et ou les firmes oligopolistiques se concurrencent par les quantites on montre que meme si une concurrence plus intense dans le marche du produit accroit la production et reduit le prix ceci n entraine pas necessairement un taux de chomage plus bas ou un niveau de salaire plus eleve pour les travailleurs selon les technologies la relation entre l intensite de la concurrence et le niveau de l emploi respectivement salaire bien etre n est pas toujours monotone et parfois a la forme d un u inverse

the impact of the minimum wage on other wages in this paper i explore how changes in the minimum wage affect various occupational wages i postulate that other wages increase for two reasons first firms try to mitigate the deterioration in a worker s relative wage which would cause him to reduce his work effort and second there is an increase in the demand for nonminimum wage workers wage adjustment patterns are examined to ascertain whether wage comparisons play a role in the adjustment process the empirical work shows a short run wage compression among white collar occupations which is consistent with the wage comparison model however large standard errors make inferences weak

unemployment and other nonemployment benefits unemployment benefit systems in most oecd countries have become more generous since the early 1960s the coverage rate has increased the level of benefits has increased relative to the predisplacement wages and maximum benefit periods in unemployment insurance systems have become longer moreover work availability and willingness to work requirements have most likely been enforced less effectively in the high unemployment environment since the late 1970s the changes in benefit systems have contributed to higher unemployment but may also have increased labor force participation the article stresses the potential importance of invalidity early retirement and sickness benefit systems for labour market outcomes in half of oecd countries the number of recipients of these benefits exceeds the official numbers of unemployed higher replacement ratios in these alternative systems than in unemployment insurance may encourage a migration towards the higher benefit systems but the extent to which this happens depends on administration of the schemes copyright 1995 by oxford university press

job queues and wages this paper uses job applications data to investigate the relationship between job queues and wage differentials the main finding is that openings for jobs that pay the minimum wage attract more job applicants than jobs that pay either slightly more or slightly less than the minimum wage this spike in the job application rate distribution suggests that ex ante rents generated for employees by an above market level minimum wage are not completely dissipated by reductions in nonwage benefits in addition we find that highly unionized firms large firms and firms in high wage industries tend to receive relatively many job applicants for openings

interindustry wage differentials technology adoption and job polarization abstract based on observations that high wage industries in 1980 experienced more evident job polarization between 1980 and 2009 we hypothesize that the persistent structure of interindustry wage differentials leads to heterogeneity in job polarization across industries as the relative price of ict capital declines firms respond to exogenous wage differentials by replacing routine workers with capital our empirical analysis shows that during the last three decades the annualized growth rate of ict capital per worker increased by 0 34 percent and that of routine employment decreased by 0 41 percent in the u s industries that paid 10 percent higher wages in 1980

the effects of privatization on efficiency how does privatization work summary uncovering the effects of privatization is difficult because privatization of a particular firm usually is not an accident this paper tests the effects of privatization on productive and allocative market efficiency using a rich panel data set of 22 privatized cement plants from turkey in the 1983 99 period since all public cement firms were privatized and we have pre and post privatization data for all we are able to avoid the problem of endogeneity associated with sample selection our analysis goes beyond just examining the privatization effects and explores how privatization really works changes in objectives of the firm ownership effect and changes in market structure environment effect may both be responsible for privatization outcomes we find that ownership effects are sufficient to achieve improvements in labor productivity our results on allocative efficiency however are dependent on changes in the competitive environment while all plants seem to improve labor productivity through work force reductions plants privatized to foreign buyers also increase their capital and investment significantly

the bubble game a classroom experiment we propose a simple classroom experiment on speculative bubbles the bubble game this game is useful to discuss about market efficiency and trading strategies in a financial economics course and about behavioral aspects in a game theory course at all levels the bubble game can be played with any number of students as long as this number is strictly greater than one students sequentially trade an asset which is publicly known to have a fundamental value of zero if there is no cap on asset prices speculative bubbles can arise at the nash equilibrium because no trader is ever sure to be last in the market sequence otherwise the nash equilibrium involves no trade bubbles usually occur with or without a cap on prices traders who are less likely to be last and have less steps of reasoning to perform to reach equilibrium are in general more likely to speculate

the culture of policy making in the transition from socialism price policy in mongolia in this article we argue that the history of policy making can deeply influence current economic policy decisions in reforming socialist countries history s impact lies beyond the rigidity of inherited organizations it acts separately from the inherited allocation of power and property rights notions and practices that are a product of past historical experience are an autonomous force in the development of policy and they endure even when policymakers deeply desire change many labels could be attached to the phenomena we describe we have chosen the word culture because the most common interpretation of that term captures the essence of what we hope to convey the central element of culture a common set of beliefs and practices resulting from a shared historical experience is exactly the phenomenon on which we focus as explained in section ii our treatment of culture is consistent with standard methodology applied to a setting in which informational and learning processes are all important in fact our conclusions on mongolian price policy exemplify douglass c north s point that the historically derived perceptions of the actors shape the choices that they make and the imperfect and fumbling efforts of the actors reflect the difficulties of deciphering a complex environment with the available mental constructs ideas theories and ideologies 2 the article s stimulus was provided by observation of the tortuous progress of price reform in mongolia with much fanfare mongolia s government proclaimed a policy of rapid and complete price liberalization the commitment to liberalization was both genuine and widespread there was a general aspiration within society to move to a market economy however in the turn from abstraction to action the details of legislation the rules embodied in regulations and policy

labor market dynamics when unemployment is a worker discipline device efficiency wage models of the effort elicitation type have important implications for labor market dynamics these models have a wide array of discontinuous sunspot equilibria driven by extraneous variables in addition to well behaved equilibria characterized by continuous slowly adjusting patterns of employment many aspects of actual labor markets can be replicated by these models for example the longer run movements they predict in employment allow macroeconomic evidence for a large labor supply elasticity to be reconciled with panel data evidence for a small labor supply elasticity many testable but as yet untested predictions about labor market dynamics can also be generated this abstract was borrowed from another version of this item

exit and voice after mass privatization the case of russia abstract mass privatization programs attempt to effect a global transformation of the economic and political environment since specific designs of such programs are shaped by the necessity to generate ex ante political support for a massive ownership transformation they may result in allocating control rights to agents who have incentives to oppose rather than to effect reallocation of resources within and across firms exemplifying this political exigency of the reform process the russian mass privatization program gave to enterprise insiders majority ownership in as many as 70 of russian companies the largest outside owners to emerge in the overwhelming majority of the companies in the insider dominated russian economy were the voucher privatization funds in this paper we attempt to shed some light on the corporate governance role and strategies of this group of outside investors we focus on two particular strategies of funds activities shareholder activism voice and trading exit each of which has different costs and benefits in postcommunist transition economies than in advanced market systems the econometric analysis is based on data collected in an empirical survey of 148 voucher investment funds in 28 different regions of russia the funds surveyed held stakes in 4 000 to 5 000 privatized companies thus offering a genuine window on the world of russian firms and their new institutional shareholders

competition and privatization amidst weak institutions evidence from mongolia mongolia s mass privatization program was implanted in a country that lacked the very basic institutions of capitalism this paper examines the effects of competition and ownership on the efficiency of the newly privatized enterprises using a representative sample of enterprises and controlling for possible selection biases competition has quantitatively large effects perfectly competitive firms having nearly double the efficiency of monopolies enterprises with residual state ownership appear to be more efficient than other enterprises reflecting an environment where the government was pressured to focus on efficiency and institutions gave little voice to outsider owners jel p0 l1 l33 o12

supervision and wages across industries this paper uses supervision data from a supplement to the 1977 wave of the panel survey of income dynamics to examine differences in supervision and wages across industries and to evaluate relationships between supervision practices and interindustry wage differentials the results demonstrate that workers in high wage industries are supervised with equal or greater stringency than secondary sector workers further the results offer no evidence that interindustry differences in monitoring contribute to interindustry wage differentials such findings appear to contradict explanations for industry wage premiums that are motivated by efficiency wage models of shirking copyright 1993 by mit press

insider ownership human resource strategies and performance in a transition economy researchers and potential investors in transition economies need to understand the human resource management hrm strategies of target firms since human resources are arguably their most valuable assets understanding is difficult however because hrm strategies help to determine firms performance but are in turn influenced by corporate governance particularly insider ownership this paper employs a structural equation modeling methodology to examine the relations between governance hrm strategies and performance in the context of a novel dataset of ukrainian industrial firms it is found that insider ownership is positively associated with high commitment hrm strategies and negatively with low commitment cost cutting hrm strategies cost cutting hrm strategies are in turn associated with weaker firm performance these outcomes correspond broadly with theoretical expectations

efficiency wages and wage dispersion the efficiency wage hypothesis has normally been used to generate an equilibrium level of unemployment the authors use it instead to generate an equilibrium wage distribution this paper starts by generalizing the previous work of r m solow in this area they then use their results on effort wage elasticities to derive a model of wage dispersion the wage rate is shown to be an increasing function of the damage potential of workers that is workers with the highest damage potential receive the highest wage the analysis of the equilibrium of the wage distribution provides interesting qualitative insights into the nature of actual wage differentials copyright 1991 by the london school of economics and political science

on the ingredients for bubble formation informed traders and communication bubbles in asset markets have been documented in numerous experiments most experiments in which bubbles occur feature a declining fundamental value this feature has been criticized for being atypical of real financial markets here we experimentally study other ingredients for bubble formation that are common in such markets namely the existence of inside information and communication among traders we find that bubbles and mirages can occur if these additional ingredients are present in particular the mere possibility that some traders are better informed than others can create bubbles surprisingly communication turns out to be counterproductive for bubble formation

when does privatization work the impact of private ownership on corporate performance in the transition economies this paper compares the performance of privatized and state firms in the transition economies of central europe while controlling for various forms of selection bias it argues that privatization has different effects depending on the types of owners to whom it gives control in particular privatization to outsider but not insider owners has significant performance effects where privatization is effective the effect on revenue performance is very pronounced but there is no comparable effect on cost reduction overlooking the strong revenue effect of privatization to outsider owners leads to a substantial overstatement of potential employment losses from postprivatization restructuring

privatization benefits in eastern europe abstract we document changes in the performance of over 6000 privatized and state owned manufacturing enterprises in seven eastern european countries over the initial transition period we find that privatization is associated with significant increases in sales revenues and labor productivity and to a lesser extent with fewer job losses the positive effect of privatization is stronger in economic magnitude and statistical significance as the time elapsed since privatization increases enterprises privatized for less than 2 years have labor productivity growth similar to that of state owned enterprises in contrast enterprises privatized for 3 or more years significantly outperform state owned enterprises the results are robust to the use of alternative econometric specifications fixed effects cluster effects and random effects and survive in six of the seven individual country samples the exceptions being hungary for sales growth and romania for labor productivity growth

a theory of dual labor markets with application to industrial policy discrimination and keynesian unemployment this paper develops a model of dual labor markets based on employers need to motivate workers in order to elicit effort from their workers employers may find it optimal to pay more than the going wage this changes fundamentally the character of labor markets the model is applied to a wide range of labor market phenomena it provides a coherent framework for understanding the claims of industrial policy advocates it also can provide the basis for a theory of occupational segregation and discrimination that will not be eroded by market forces finally the model provides the basis for a theory of involuntary unemployment

the inefficiency of unemployment the supervision perspective we study an example economy with costly labor monitoring under a wage cum supervision arrangement where workers utilities are not equalized across sectors workers are identical to each other our main task is to look for and find a set of flat taxes and subsidies that bring about a pareto improvement over the laissez faire solution we show that any of such welfare improving schemes involves a tax on labor income from those workers whose utility is the lowest

how do we know that real wages are too high it is common belief that the wages that we observe are above the level that would prevail in a competitive labour market and also it is common to believe that wage moderation should be encouraged as a way to keep unemployment down this paper considers whether we can have confidence in these beliefs it presents a number of models designed to cast doubt on the conventional wisdom first we show that in an efficiency wage model in which there is involuntary unemployment a binding minimum wage may increase employment we then present a general equilibrium matching model in which there is involuntary unemployment but wages are below market clearing levels and raising wages can reduce unemployment we then consider the empirical evidence on employment and wage determination to argue that it is just as consistent with this model as with models in which wages are at or above market clearing levels

price bubbles gender and expectations in experimental asset markets abstract this paper reports results of laboratory markets for a risky asset with a flat fundamental value that equates expected dividends to the return on a safe asset subjects were sorted by gender in an unobtrusive manner and bubbles in this setting are pervasive and of comparable magnitude for both genders in contrast a robustness check done with a declining fundamental value did generate larger bubbles for groups of males elicited price forecasts tend to trail share prices as they rise and exceed prices as they fall a pattern that is tracked by a double adaptive forecasting model

ownership agency and wages an examination of franchising in the fast food industry this paper estimates the difference in compensation between company owned and franchisee owned fast food restaurants the contrast is of interest because contractual arrangements give managers of company owned outlets less of an incentive to monitor and supervise employees estimates based on two data sets suggest that employee compensation is slightly greater at company owned outlets than at franchisee owned outlets the earnings gap is 9 percent for assistant and shift managers and 2 percent for full time crew workers furthermore the tenure earnings profile is steeper at company owned restaurants these findings suggest that monitoring difficulties influence the timing and generosity of compensation

enterprise performance and management turnover in the czech republic abstract we study the effect of management turnover on changes in enterprise performance using a cross section of 706 czech firms over the 1993 1997 period controlling for initial conditions equity holdings by managers and firm and sector specific effects we find that the appointment of new managers is associated with improvements in profit margins and labor productivity particularly if those managers were selected by private owners the results highlight the importance of human capital in transition economies in bringing about improvements in corporate performance

trade and exchange rate policies in formerly centrally planned economies this paper examines the international economic policies of the eastern european and soviet successes states in the early 1990s which provide one of those wide open windows of opportunity when powerful vested interests are not lobbying for retention of an existing tariff structure moreover the simultaneous abandonment of central planning by over two dozen countries provided a natural experiment in which a range of differing policies might have been pursued policymakers in transition economies have generally ended up pursuing liberal non discriminatory trade and foreign exchange policies there are exceptions and the majority may be wrong but the presumption is that perhaps after a learning or trial and error process decision makers have found the rules of thumb suggested by economists to be their best guide to international economic policy this paper notes that integration of transition economies into the global trading system has been surprisingly successful almost all the countries in transition from central planning have accepted the wto rule based system in principle even if there are variations in trade policies and performance and have generally pursued multilateral non discriminatory trade policies in particular the potential danger of regionalism proving more attractive than multilateralism has not eventuated the revealed behaviour of policymakers suggests that trade liberalisation is a good rule of thumb and regional groupings among transition economies have been insignificant despite a proliferation of new currencies varying exchange rate regimes and differing degrees of currency convertibility the general pattern has been to accept convertibility for current account transdactions and in many cases to extend this to a de jure commitment and to allow substantial capital account convertibility a general policy conclusion in favour of more open and non discriminatory trade and exchange policies have passed the test of acceptability by policymakers in over two dozen countries in this category

local governments as industrial firms an organizational analysis of china s transitional economy despite widespread skepticism about government ownership in transitional economies china s rapid industrial growth has been led by public enterprises kornai s theory of soft budbet constraints born of the failure of earlier hungarian reforms fosters such skepticism but it assumes as fixed organizational characteristics that in fact vary widely across government jurisdictions local governments with smaller industrial bases have clearer financial incentives and constraints fewer nonfinancial interests in enterprises and a greater capacity to monitor them in china s vast public sector the fastest growth in output and productivity has occurred where government ownership rights are clearest and most easily enforced which enables officials to manage public industry as a diversified market oriented firm

a review of bubbles and crashes in experimental asset markets this paper discusses the literature on bubbles and crashes in the most commonly used experimental asset market design introduced by smith et al it documents the main findings based on the results from 41 published papers 3 book chapters and 20 working papers

empirical tests of efficiency wage models two digit manufacturing industry level production functions are used to test efficiency wage propositions conclusive tests require functional forms which allow differences in elasticities of substitution between observable human capital wage premia and other inputs results demonstrate that unexplained industry wage premia and higher unemployment rates raise productivity wage premia and the human capital wage component cannot be aggregated into a single human capital index nevertheless 88 of the productivity effect associated with industry wages can be tied to observable human capital in the industry with only 12 associated with the wage premium

privatization financial development property rights and growth abstract this study analyzes how prevailing institutional arrangements i e property rights contracting rights political institutions and corporate governance practices affect privatized firms performance capital markets development and economic growth most of the studies surveyed show that privatization enhances privatized firms performance efficiency and profitability which percolates to economic growth privatized firms performed better in countries with better regulatory and legal frameworks partial privatization may be beneficial in countries with weak institutions namely the french civil law countries the stronger the economic and the governing institutions the easier it is for privatized firms to thrive and contribute to economic growth overall privatization allows firms to achieve improved efficiency while driving the development of the financial sector
