vehicle scrappage and gasoline policy abstract we estimate the sensitivity of scrap decisions to changes in used car values and show how this scrap elasticity produces emissions leakage under fuel efficiency standards a process known as the gruenspecht effect we first estimate the effect of gasoline prices on used vehicle values and scrappage of vehicles with different fuel economies we then estimate the scrap elasticity itself which we find to be 0 7 when applied in a model of fuel economy standards 13 16 percent of the expected fuel savings leak away through the used vehicle market this effect rivals or exceeds the importance of the often cited mileage rebound effect jel h23 l62 l78 q35 q38 q48 q58

do doctors practice defensive medicine defensive medicine is a potentially serious social problem if fear of liability drives health care providers to administer treatments that do not have worthwhile medical benefits then the current liability system may generate inefficiencies much larger than the costs of compensating malpractice claimants to obtain direct empirical evidence on this question we analyze the effects of malpractice liability reforms using data on all elderly medicare beneficiaries treated for serious heart disease in 1984 1987 and 1990 we find that malpractice reforms that directly reduce provider liability pressure lead to reductions of 5 to 9 percent in medical expenditures without substantial effects on mortality or medical complications we conclude that liability reforms can reduce defensive medical practices

reform of the coal sector in an open economy the case of china cheap abundant and easy to transport and store coal has been produced and consumed to meet people s energy needs the last decade s growth in global coal use has been driven mainly by developing economies like china whose phenomenal economic growth has been powered by coal fired electricity and promoted by the export of manufactured goods a recent reform focus in china s coal sector is on coal taxation the paper develops a game theoretic model tailored to the context of china where coal taxation reform takes place against the background of privatisation of coal firms and an open economy it finds that the adoption of special coal taxes is optimal for social welfare under most circumstances but may induce coal firms to commit opportunistic behaviour in the process of privatisation the paper also cautions about potential resistance to the reform from consumers coal firms and government officials

management ownership and market valuation an empirical analysis we investigate the relationship between management ownership and market valuation of the firm as measured by tobin s q in a 1980 cross section of 371 fortune 500 firms we find evidence of a significant nonmonotonic relationship tobin s q first increases then declines and finally rises slightly as ownership by the board of directors rises for older firms there is evidence that q is lower when the firm is run by a member of the founding family than when it is run by an officer unrelated to the founder

a comparison of salient rewards in experiments money and class points abstract we use laboratory decisions with different salient rewards to elicit individual values of a risk mitigation investment in a low probability environment statistically significant gender differences were found with class points however gender differences disappeared when monetary incentives were used

incumbent employees resistance to implementing privatization policy abstract the recent anti privatization trend in latin america france and south africa is a reminder that employees resist privatization because pre privatization firms tend to be over manned and to pay excessive wages we study the effect of employees resistance on the successful implementation of privatization in a stylized model in which the government interacts with employees of an unknown type the analysis clarifies some of the difficulties associated with the implementation process furthermore although common sense dictates that the government negotiates with the employees before finding an outside buyer we show that sometimes it is better off contacting an investor first

environmental performance of state owned and privatized eastern european energy utilities abstract privatization in eastern europe has helped in the transition of the region s economies from planned to free market however the effects of privatization on the environment are relatively unknown and many firms remain under state ownership today we compare the environmental performance of state owned and privatized energy utility plants in eastern europe utilizing a novel panel data that includes reported sulfur dioxide emissions energy input and ownership status we find that state owned plants emit more sulfur dioxide than privately owned plants this is environmentally significant as privatization is associated with a reduction in emissions of about 55

leviathan resists the endogenous relationship between privatization and firm performance using a panel dataset of privatized cement firms in turkey this paper models and finds support for the simultaneous relationship between privatization and firm performance it is found that favorable short run performance weak market potential higher employment lower socio economic development concentrated voter preferences and weaker representation of right wing parties in the firms locality delay the timing of privatization the paper also finds that privatization increases output in the medium term by reducing the labor stock and promoting the adoption of more advanced technology such that production shifts from constant to decreasing returns to scale

returns to skills around the world evidence from piaac abstract existing estimates of the labor market returns to human capital give a distorted picture of the role of skills across different economies international comparisons of earnings analyses rely almost exclusively on school attainment measures of human capital and evidence incorporating direct measures of cognitive skills is mostly restricted to early career workers in the united states analysis of the new piaac survey of adult skills over the full lifecycle in 23 countries shows that the focus on early career earnings leads to underestimating the lifetime returns to skills by about one quarter on average a one standard deviation increase in numeracy skills is associated with an 18 percent wage increase among prime age workers but this masks considerable heterogeneity across countries eight countries including all nordic countries have returns between 12 and 15 percent while six are above 21 percent with the largest return being 28 percent in the united states estimates are remarkably robust to different earnings and skill measures additional controls and various subgroups instrumental variable models that use skill variation stemming from school attainment parental education or compulsory schooling laws provide even higher estimates intriguingly returns to skills are systematically lower in countries with higher union density stricter employment protection and larger public sector shares

gasoline prices fuel economy and the energy paradox abstract policymakers often assert that consumers undervalue future gasoline costs when they buy automobiles we test this by measuring whether relative prices of vehicles with different fuel economy ratings fully adjust to variation in gasoline prices vehicle prices move as if consumers are indifferent between 1 00 in discounted future gas cost and 0 76 in vehicle purchase price we show how corrections for endogenous market shares and utilization measurement error and different gasoline price forecasts affect the results we also provide unique evidence of sticky information vehicle markets respond to changes in gasoline prices with up to a six month delay

the financial and operating performance of newly privatized firms an international empirical analysis this study compares the pre and postprivatization financial and operating performance of 61 companies from 18 countries and 32 industries that experience full or partial privatization through public share offerings during the period 1961 to 1990 our results document strong performance improvements achieved surprisingly without sacrificing employment security specifically after being privatized firms increase real sales become more profitable increase their capital investment spending improve their operating efficiency and increase their work forces furthermore these companies significantly lower their debt levels and increase dividend payout finally we document significant changes in the size and composition of corporate boards of directors after privatization the last fifteen years have witnessed a significant global shift away from state socialism towards entrepreneurial capitalism one of the most important and visible aspects of this trend has been the enthusiasm with which governments of all political persuasions have sold their state owned enterprises soes to private investors in hopes that the generally unsatisfactory economic performance of these firms can be improved by the discipline of private ownership this denationalization process given its current title of privatization by the conservative government of margaret thatcher in

insider power and wage setting in transition evidence from a panel of large polish firms 1988 1994 abstract we analyse wage setting behaviour in the period of transition using the right to manage model the results show a significant change in wage bargaining in 1990 however the insider power measured by the employees capacity to capture productivity gains persists the sensitivity of wages to productivity changes is much stronger on the upside than on the downside in soes insiders capture important part of labour productivity gains in firms transformed into treasury owned joint stock companies insider effect is weaker in privatised firms the bargaining power of the employees is too weak to let them push up wages in response to labour productivity growth these results are robust to the potential selection bias

the benefits of privatization evidence from mexico critics of privatization often argue that its benefits come at a high cost to society the authors test the validity of this criticism for mexico s privatization program one of the world s largest case by case programs assessing the performance of newly privatized firms in such areas as profitability and efficiency they find that these firms quickly close the gap with their peers in the private sector their findings suggest that the firms profit gains come from productivity gains 52 percent layoffs 33 percent and higher prices 15 percent

gasoline prices gasoline consumption and new vehicle fuel economy evidence for a large sample of countries abstract countries differ considerably in terms of the price drivers pay for gasoline this paper uses data for 132 countries for the period 1995 2008 to investigate the implications of these differences for the consumption of gasoline for road transport to address the potential for simultaneity bias we use both a country s oil reserves and the international crude oil price as instruments for a country s average gasoline pump price we obtain estimates of the long run price elasticity of gasoline demand of between 0 2 and 0 5 using newly available data for a sub sample of 43 countries we also find that higher gasoline prices induce consumers to substitute to vehicles that are more fuel efficient with an estimated elasticity of 0 2 despite the small size of our elasticity estimates there is considerable scope for low price countries to achieve gasoline savings and vehicle fuel economy improvements via reducing gasoline subsidies and or increasing gasoline taxes

capital reallocation and liquidity this paper studies the cyclical properties of capital reallocation and the frictions which inhibit such reallocation we show that the amount of capital reallocation and the benefits to reallocation vary at the business cycle frequency the amount of capital reallocation is procyclical in contrast the benefits to capital reallocation appear countercyclical we measure the amount of reallocation using data on flows of capital across firms and the benefits to capital reallocation using several measures of the cross sectional dispersion of the productivity of capital we then study a calibrated model of an economy where capital reallocation is costly and impute the cost of reallocation which is consistent with the amount of and benefits to reallocation in the data we find that the cost of reallocation needs to be substantially countercyclical to be consistent with the observed joint cyclical properties of reallocation and productivity dispersion the cyclical variation in this cost is interpreted as variation in the liquidity of capital broadly defined since physical costs are unlikely to vary countercyclically

why can t us airlines make money us airlines have lost nearly 60 billion 2009 in domestic markets since the 1978 deregulation most of it in the last decade the dismal financial record challenges the economics of deregulation i examine some of the common explanations among industry participants and researchers including high taxes and fuel costs weak demand and competition from lower cost airlines major drivers seem to be the demand downturn after 9 11 demand remains much weaker today than in 2000 and the large cost differential between legacy and low cost carriers which has persisted even as the price differential between them has greatly declined

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

ownership concentration in privatized firms the role of disclosure standards auditor choice and auditing infrastructure we rely on a unique data set to estimate the impact of disclosure standards and auditor related characteristics on ownership concentration in 190 privatized firms from 31 countries accounting transparency can help alleviate the agency conflict between minority investors and controlling shareholders which is evident in the extent of ownership concentration since the expropriation of corporate resources by insiders hinges on these private benefits remaining hidden after controlling for other country level and firm level determinants we find weak no evidence that extensive disclosure standards auditor choice reduce ownership concentration in contrast we provide strong robust evidence that ownership concentration is lower in countries with securities laws that specify a lower burden of proof in civil and criminal litigation against auditors consistent with ball s 2001 predictions collectively our research implies that minority investors worldwide value legal institutions that discipline auditors in the event of financial reporting failure over both the presence of a big five auditor and better disclosure standards

effect of corporate economic performance on firm level environmental performance in a transition economy this paper analyzes the effect of corporate economic performance as measured by value added on firm level environmental performance in a transition economy in particular it analyzes this economic performance effect using an unbalanced panel of czech firms for the years 1995 1998 it assesses whether successful economic performance begets or undermines good environmental performance this connection seems especially important in transition economies since firms are dramatically restructuring their economic management approaches during transitional periods a majority of the analytical results indicate that successful economic performance undermines good environmental performance possibly indicating that more focused managerial efforts to improve economic outcomes may distract efforts to manage environmental matters better

a comparison between economic systems with an application to transition abstract this paper develops a general equilibrium theory of endogenous firm and class formation under non contractibility with heterogeneous individuals a collectivist economy a private ownership economy and a mixed economy are compared on the basis of identical economic fundamentals methodological symmetry each economic system generates specific inefficiencies so that none dominates the others in general the main trade off is between the welfare loss associated with risk taking in the private ownership economy and the informational problems in the collectivist economy we then use this framework to study the political economy of transition between economic systems and provide detailed welfare results

the effect of arrests on the employment and earnings of young men many young men commit crime and many are arrested i estimate the effect of arrests on the employment and earnings of arrestees using a large longitudinal data set constructed by merging police records with ui earnings data i find that the effects of arrests are moderate in magnitude and rather short lived

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

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

flying more efficiently joint impacts of fuel prices capital costs and fleet size on airline fleet fuel economy abstract we investigate the factors that affect airlines choice of fleet fuel economy using aircraft level data for 1267 airlines in 174 countries larger and newer aircraft are usually more fuel efficient controlling for the effect of aircraft size and age we find that the technically achievable fleet fuel economy improves with the size of airlines and the price of fuel and worsens with higher capital costs the elasticity of fuel economy with respect to the price of fuel is between 0 07 and 0 13 we find evidence for regional differences in fleet fuel economy that are attributable to the adoption of distinct groups of technologies

priorities and sequencing in privatization evidence from czech firm panel data abstract while privatization of state owned enterprises has been one of the most important aspects of the economic transition from a centrally planned to a market system no transition economy has privatized all its firms simultaneously this raises the question of whether governments privatize firms strategically in this paper we examine the determinants of the sequencing of privatization to obtain testable predictions about the factors that may affect sequencing we investigate the following competing government objectives i maximizing efficiency through resource allocation ii maximizing public goodwill from the free transfers of shares to the public iii minimizing political costs iv maximizing efficiency through information gains and v maximizing privatization revenues next we use firm level data from the czech republic to test the competing predictions about the sequencing of privatization consistent with the hypotheses of a government priority on revenues and public goodwill we find strong evidence that more profitable firms were privatized first the sequencing of privatization is also consistent with maximizing efficiency through information gains our results indicate that many empirical studies of the effects of privatization on firm performance suffer from a selection bias

cross hedging jet fuel price exposure abstract this paper investigates the cross hedging performance of several oil forwards contracts using wti brent gasoil and heating oil to manage jet fuel spot price exposure we apply three econometric techniques that have been widely tested and applied in the cross hedging literature on foreign exchange and stock index futures markets using quotes from the financial industry on forward contracts we can show that the optimal cross hedging instrument depends on the maturity of the instrument s forwards contract the results highlight that the standard approach in the literature to use crude oil as a cross hedge is not optimal for time horizons of three months or less by contrast for short hedging horizons our results indicate that gasoil forwards contracts represent the highest cross hedging efficiency for jet fuel spot price exposure while for maturities of more than three months the predominance of gasoil diminishes in comparison to wti and brent

regulation competition and liberalization in many countries throughout the world regulators are struggling to determine whether and how to introduce competition into regulated industries this essay examines the complexities involved in the liberalization process while stressing the importance of case specific analyses this essay distinguishes liberalization policies that generally are procompetitive from corresponding anticompetitive liberalization policies

the real effects of government owned banks evidence from an emerging market using plant level data for brazilian manufacturing firms this paper provides evidence that government control over banks leads to significant political influence over the real decisions of firms i find that firms eligible for government bank lending expand employment in politically attractive regions near elections these expansions are associated with additional favorable borrowing from government banks further these persistent expansions take place just before competitive elections and are associated with lower future employment growth by firms in other regions the analysis suggests that politicians in brazil use bank lending to shift employment towards politically attractive regions and away from unattractive regions

models of technology diffusion abstract the literature on new technology diffusion is vast and it spills over many conventional disciplinary boundaries this paper surveys the literature by focusing on alternative explanations of the dominant stylized fact that the usage of new technologies over time typically follows an s curve the most commonly found model which is used to account for this model is the so called epidemic model which builds on the premise that what limits the speed of usage is the lack of information available about the new technology how to use it and what it does the leading alternate model is often called the probit model which follows from the premise that different firms with different goals and abilities are likely to want to adopt the new technology at different times in this model diffusion occurs as firms of different types gradually adopt it there are actually many ways to generate an s curve and the third class of models which we examine are models of density dependence popularized by population ecologists in these models the twin forces of legitimation and competition help to establish new technologies and then ultimately limit their take up finally we look at models in which the initial choice between different variants of the new technology affect the subsequent diffusion speed of the chosen technology such models often rely on information cascades which drive herd like adoption behaviour when a particular variant is finally selected

examining risk preferences under high monetary incentives experimental evidence from the people s republic of china several experimental sessions were conducted to elicit certainty equivalents for a sequence of lotteries involving real monetary outcomes the opportunity to conduct sessions in the people s republic of china afforded the ability to offer very large monetary incentives relative to subjects living costs in the highest payoff condition subjects earned three times their normal monthly revenue in the course of a two hour experiment results indicate a statistically significant impact of the level of monetary incentives on revealed risk preferences however even under extreme monetary incentives subjects demanded amounts well in excess of expected value for low probability gain prospects copyright 1992 by american economic association

monetary incentives versus class credit evidence from a large classroom trust experiment this paper reports an experimental investigation of a trust game using either cash or class credit as incentives to participants we recruit from two auditorium classes in one class each token has cash value in the other each token is worth extra credit points added to the students overall average at the end of the semester the results indicate that using extra credit points to motivate participants generates qualitatively similar data on average as participants incentivized with cash we do find a difference in behavior with second movers who expect a low grade but those incentivized with class credit are closer to the game theoretic prediction

selection staging and sequencing in the recent chinese privatization selection in privatization is a decision making process of choosing state owned enterprises soes prioritizing and sequencing privatizing events and determining the extent of private ownership in partial privatization we investigate this process in an important but rarely studied case of china based on the soe population over 1998 2008 we track 49 456 wholly soes and identify 9 359 privatization cases over time our econometric analysis concludes i the privatization selection is a complex decision making process in which local governments balance between various economic financial and political objectives ii in the recent chinese privatization firm performance relates to the selection staging and sequencing in privatization in an inverted u fashion the worse and the best performing soes are more likely to remain state owned maintain higher state holding when privatized and are less likely to be privatized later in time these patterns suggest the privatization reform slowdown and the underlying changes in the privatization policy
