wages and productivity growth in a dynamic monopoly abstract this paper studies the intertemporal problem of a monopolistic firm that engages in productivity enhancing innovations to reduce labor costs the optimal innovation policy is not monotone and the rate of productivity growth is the highest when the firm s size is in some intermediate range as long as its initial productivity is not too low the firm eventually reaches a steady state where the rate of productivity growth is identical to the rate of wage growth productivity dependent wage differentials do not affect productivity growth in the steady state they increase however the firm s long run equilibrium cost level

income dispersion and counter cyclical markups recent advances in measuring cyclical changes in the income distribution raise new questions how might these distributional changes affect the business cycle itself we show how counter cyclical income dispersion can generate counter cyclical markups in the goods market without any preference shocks or price setting frictions in recessions idiosyncratic labor productivity shocks raise income dispersion lower the price elasticity of demand and increase imperfectly competitive firms optimal markups the calibrated model explains not only many cyclical features of markups but also cyclical and long run patterns of standard business cycle aggregates

the cost of contract renegotiation evidence from the local public sector the renegotiation of regulatory contracts is known to prevent regulators from achieving the full commitment efficient outcome in dynamic contexts however assessing the cost of such renegotiation remains an open issue from an empirical viewpoint to address this question we fit a structural principal agent model with renegotiation on a set of urban transport service contracts the model captures two important features of the industry first only two types of contracts are used in practice fixed price and cost plus second subsidies increase over time we compare a scenario with renegotiation and a hypothetical situation with full commitment we conclude that the welfare gains from improving commitment would be significant but would accrue mostly to operators

the low skill trap recently it has become popular to argue that certain workers have fallen into a trap in which they have poor skills few job opportunities and a low return on training while others have not this paper demonstrates how such a trap can occur within a simple matching model with rent sharing rent sharing diminishes the worker s incentive to acquire skills however since firms also benefit from training rent sharing likewise induces job creation the subsequent improved matching prospects may offset the initial disincentive to invest however for this mechanism to be effective firms and workers must coordinate their actions if they do not the trap occurs

time series analysis of market power evidence from g 7 manufacturing abstract this paper estimates the mark up of price over marginal cost in manufacturing for the seven major oecd countries applying hall s approach to market power measurement we have estimated the cyclical behaviour of the mark up a substantial degree of market power has been estimated in all countries examined and procyclical movements in the mark up competition seems to affect the level of mark up negatively

effects of the change from rate of return to price cap regulation this article focuses on the use of incentive regulation in the telephone industry in the united states we first characterize some of the difficulties that have led regulators to move away from traditional rate ofreturn cost based regulation and toward systems of regulation that provide incentives for increasingly efficient production allowing firms to share in the social gains from efficiency with increased profits we then discuss the basic structure of incentive regulation as it has most commonly been adopted in the telephone industry in the united states the first is price cap pc regulation which typically allows the firm to

unionisation structures and innovation incentives this paper examines how dierent unionisation structures aect rms innovation incen tives and industry employment we distinguish three modes of unionisation with increasing degree of centralisation 1 decentralisation where wages are determined independently at the rm level 2 coordination where one industry union sets individual wages for all rms and 3 centralisation where an industry union sets a uniform wage rate for all rms while rms investment incentives are largest under centralisation investment in centives are non monotone in the degree of centralisation decentralisation carries higher investment incentives than coordination labour market policy can spur innovation by decentralising unionisation structures or through non discrimination rules

crime rates and local labor market opportunities in the united states 1979 1997 the labor market prospects of young unskilled men fell dramatically in the 1980s and improved in the 1990s crime rates show a reverse pattern increasing during the 1980s and falling in the 1990s because young unskilled men commit most crime this paper seeks to establish a causal relationship between the two trends previous work on the relationship between labor markets and crime focused mainly on the relationship between the unemployment rate and crime and found inconclusive results in contrast this paper examines the impact of both wages and unemployment on crime and uses instrumental variables to establish causality we conclude that both wages and unemployment are significantly related to crime but that wages played a larger role in the crime trends over the last few decades these results are robust to the inclusion of deterrence variables controls for simultaneity and controlling for individual and family characteristics

tariff based incentives for improving coal power plant efficiencies in india improving the efficiency of coal based power plants plays an important role in improving the performance of india s power sector it allows for increased consumer benefits through cost reduction while enhancing energy security and helping reduce local and global pollution through more efficient coal use a focus on supply side efficiency also complements other ongoing efforts on end use efficiency the recent restructuring of the indian electricity sector offers an important route to improving power plant efficiency through regulatory mechanisms that allow for an independent tariff setting process for bulk purchases of electricity from generators current tariffs based on normative benchmarks for performance norms are hobbled by information asymmetry where regulators do not have access to detailed performance data hence we propose a new incentive scheme that gets around the asymmetry problem by setting performance benchmarks based on actual efficiency data rather than on a normative basis the scheme provides direct tariff based incentives for efficiency improvements while benefiting consumers by reducing electricity costs in the long run this proposal might also be useful for regulators in other countries to incorporate similar incentives for efficiency improvement in power generation

unemployment institutions and reform complementarities re assessing the aggregate evidence for oecd countries there is no or limited consensus on the quantitative impact of institutions on unemployment which has led some to question the case for structural reforms recent studies suggest also that institutions interact with each other and cannot be analysed in isolation in this paper we estimate a standard reduced form model to explore the institutional determinants of unemployment and assess its robustness using a large battery of robustness checks we show that although the impact of each individual policy varies across countries due to policy interactions the simple linear model can be used to draw inferences for countries with an average mix of institutions the model is then extended to encompass systemic interactions in which individual policies interact with the overall institutional framework we find relatively robust evidence of broad reform complementarities

the effect of unemployment benefits on the duration of unemployment insurance receipt new evidence from a regression kink design in missouri 2003 2013 abstract we provide new evidence on the effect of the unemployment insurance ui weekly benefit amount on unemployment insurance spells based on administrative data from the state of missouri covering the period 2003 2013 identification comes from a regression kink design that exploits the quasi experimental variation around the kink in the ui benefit schedule we find that ui durations are more responsive to benefit levels during the recession and its aftermath with an elasticity between 0 65 and 0 9 as compared to about 0 35 pre recession

lasting or latent scars swedish evidence on the long term effects of job displacement recently improved swedish register data have made it possible to remedy many weaknesses of previous research on displaced workers using linked employer employee data we identify all workers displaced in 1987 due to an establishment closure and follow them over both a predisplacement period of 4 years and a postdisplacement period stretching until 1999 we find that the displaced workers suffer both earnings losses and worsened labor market position not only during a transitory period of adjustment but also in the longer run these longer run effects seem to be driven by an increased sensitivity to subsequent macroeconomic shocks

job loss and regional mobility we study the migration behavior of displaced workers and find that job displacement increases regional mobility we find however that noneconomic factors such as family ties are very important

optimal risk allocation for regulated monopolies and consumers abstract the model shows how a regulated monopolist s price should change as random cost and demand parameters are revealed the regulator has a ramsey type problem with a linear tariff a trade off between allocative efficiency and risk sharing typically exists the attitudes of the consumer and the firm to both income and price risk determine how the price should move sufficient conditions are found for price adjustment schemes used in practice to be optimal these schemes include full partial and zero pass through of marginal costs and price caps average cost pricing and caps on total revenue for demand risk

subjective and objective measures of governmental regulations in oecd nations abstract since government regulations may have an important impact on the macroeconomic performance of market economies it is necessary to devise quantitative indicators of the regulatory regime which raises some difficult methodological issues after reviewing some of these problems we compare the results of several recent quantitative studies of regulation in oecd nations some based on an extensive review and quantification of laws and regulations others based on observational data of those familiar with these regulations despite their very different methodologies and coverage of particular types of governmental regulation the results of the three studies are significantly correlated which suggests that they all capture the same underlying reality

testing rent sharing using individualized measures of rent evidence from domestic helpers wing suen the market for resident domestic helpers offers a rare opportunity where the surplus from employment relationship can be quantitatively measured for each individual employee using the difference between employer s cost of time and employee s wage as a measure of rent it is found that wages for domestic helpers are positively related to rent however the apparent sharing of rent is better explained by matching than by efficiency wage models rent sharing is observed even in households where monitoring or turnover costs are low rent sharing is not observed among newly arrived foreign domestic helpers whose ability remains to be revealed jel j41 i introduction this article studies the pattern of wages for resident domestic helpers in hong kong no one would lure economists into paying attention to this arcane labor market were it not for one feature of the market for housework a measure of employment rent can be plausibly assigned to each individual employee having an individualized measure of rent at the worker level instead of a general measure at the firm level will shed considerable light on the large and growing literature of rent sharing in wage determination since 1975 the hong kong government has allowed the importation of foreign domestic helpers into the territory because of large wage differences between hong kong and some of its asian neighbors the program is highly popular the census and statistics department 1995 estimates that 92 700 households or 5 6 of all domestic households in hong kong employed domestic helpers in 1993 the figure is even more dramatic for high income households 44 of households with monthly income of over hk 50 000 had one or more domestic helpers 1 one consequence of the availability of market procured housework is that women who employ helpers have more time for market work in suen 1994 i estimate that the probability of labor force participation among married women who had domestic helpers is 22 percentage points higher than that for women without domestic help other things equal if hiring a helper enables a married woman to engage in market work then a plausible measure for the rent or surplus from this employment relationship is the difference between the woman s wage and her helper s wage if a woman with a domestic helper decides to stay home nonetheless the size of the surplus can be measured by the difference between the shadow value of leisure and the helper s wage wage information is readily available from census data and shadow wages can be estimated using standard techniques this article utilizes this rare opportunity to impute a measure of rent for each employer employee pair studying how the wages of domestic helpers vary wi th the magnitude of rent will provide direct evidence for rent sharing in the labor market there is a large literature which documents the fact that the characteristics of the employer such as industry affiliation and firm size are significantly correlated with the employees wages krueger and summers 19881 brown and medoff 1989 groshen 1991 helwege 1992 and many others offer convincing evidence that inter industry wage differentials and employer wage effects exist rent sharing is often invoked to account for such wage patterns however few studies in the literature offer a plausible account for the existence of or a measure for the size of the rent that is supposedly shared 2 at the industry level dickens and katz 1987 use variables such as concentration ratio capital labor ratio research and development expenditures and average rate of return on capital as covariates in wage equations these variables provide at best an indirect and error prone measure of employment rent campbell 1993 makes use of firm level characteristics instead of industry characteristics but t here is no information on profits in his firm level data

the impact of alternative forms of state regulation of at t on direct dial long distance telephone rates federal and state regulatory agencies have traditionally used rate of return regulation to set profit and rate levels for utilities a price cap framework in which the regulatory agency sets a maximum rate below which the regulated utility has pricing flexibility is possibly a more efficient alternative to rate of return regulation this article presents an econometric analysis that compares at t s prices of intrastate long distance telephone service in states that allow at t pricing flexibility with those in states that do not the results of this analysis suggest that at t s daytime evening nighttime and weekend rates are significantly lower in states that allow pricing flexibility than in states that use rate of return regulation

the creation and capture of rents wages and innovation in a panel of u k companies this paper examines the impact of technological innovation on wages using a panel of british firms a head count measure of major innovations between 1945 and 1983 is combined with share price and accounting information innovating firms are found to have higher average wages but rival innovation tends to depress own wages this appears consistent with a model where wages are partly determined by a sharing in the rents generated by innovation in other words innovation may be a good instrument for proxies for rents such as profitability quasi rents or tobin s average q instrumental variable estimates of the elasticity between wages and quasi rents are about 0 29

job search and unemployment insurance new evidence from time use data article i nfo this paper provides new evidence on job search intensity of the unemployed in the u s modeling job search intensity as time allocated to job search activities the major findings are 1 the average u s unemployed worker devotes about 41 min to job search on weekdays which is substantially more than their european counterparts 2 workers who expect to be recalled by their previous employer search substantially less than the average unemployed worker 3 across the 50 states and d c job search is inversely related to the generosity of unemployment benefits with an elasticity between 1 6 and 2 2 4 job search intensity for those eligible for unemployment insurance ui increases prior to benefit exhaustion and 5 time devoted to job search is fairly constant regardless of unemployment duration for those who are ineligible for ui

wage compression within the firm evidence from an indexation scheme we revisit the role of labour market institutions by showing how they affect the sharing of firm specific rents between employers and employees we look at an italian wage indexation mechanism scala mobile that compressed the distribution of wages imposing real wage increases at the bottom of the distribution after developing a simplified version of a search model with intra firm bargaining and on the job search we document that skilled workers received lower wage adjustments when employed at firms with many unskilled workers and they tended to move towards more skill intensive firms moreover the system drove the least skill intensive firms out of the market

rent sharing and workers bargaining power an empirical cross country cross industry panel analysis this paper studies how rents are shared between capital and labour using industry level panel data for 19 oecd countries over the 1988 2007 period the first step is an explanation of the rent creation process we provide evidence of a significant impact of regulation on value added prices at the industry level relative to the value added price for the overall economy rent in the second step we dissect the value added sharing process running ols and iv estimations our results confirm the blanchard giavazzi 2003 prediction the impact of rents on the capital share depends on workers bargaining power this article is protected by copyright all rights reserved

regulating a monopolist with unknown demand and cost functions we consider the design of regulatory policy when the regulator is imperfectly informed about both the firm s cost function and the demand function it faces to some extent the optimal policy here is the natural combination of the optimal policies when there is uncertainty only about either demand or cost important qualitative differences also exist however for example it may be optimal to set prices below marginal cost and the pricing authority delegated to the firm may be more limited when there is uncertainty about both cost and demand

juvenile incarceration human capital and future crime evidence from randomly assigned judges over 130 000 juveniles are detained in the united states each year with 70 000 in detention on any given day yet little is known about whether such a penalty deters future crime or interrupts social and human capital formation in a way that increases the likelihood of later criminal behavior this article uses the incarceration tendency of randomly assigned judges as an instrumental variable to estimate causal effects of juvenile incarceration on high school completion and adult recidivism estimates based on over 35 000 juvenile offenders over a 10 year period from a large urban county in the united states suggest that juvenile incarceration results in substantially lower high school completion rates and higher adult incarceration rates including for violent crimes in an attempt to understand the large effects we found that incarceration for this population could be very disruptive greatly reducing the likelihood of ever returning to school and for those who do return significantly increasing the likelihood of being classified as having an emotional or behavioral disorder jel codes k140 i210

rent creation and rent sharing new measures and impacts on total factor productivity this analysis proposes new measures of rent creation and rent sharing and assesses their impact on productivity on cross country industry panel data we find first that 1 anticompetitive product market regulations positively affect rent creation and 2 employment protection legislation boosts hourly wages particularly for low skill workers however we find no significant impact of this employment legislation on rent sharing as the hourly wage increases are offset by a negative impact on hours worked second using regulation indicators as instruments we find that rent creation and rent sharing both have a substantial negative impact on total factor productivity jel e22 e24 o30 l50 o43 o47 c23

the crime reducing effect of education in this article we study the crime reducing potential of education presenting causal statistical estimates based upon a law that changed the compulsory school leaving age in england and wales we frame the analysis in a regression discontinuity setting and uncover significant decreases in property crime from reductions in the proportion of people with no educational qualifications and increases in the age of leaving school that resulted from the change in the law the findings show that improving education can yield significant social benefits and can be a key policy tool in the drive to reduce crime

rent sharing holdup and wages evidence from matched panel data rent sharing by workers can reduce the incentives for investment if some of the returns to sunk capital are captured in higher wages we propose a simple measure of this holdup effect based on the size of the wage offset for firm specific capital accumulation using social security earnings records for workers in the veneto region of italy linked to detailed financial data for their employers we find strong evidence of rent sharing with an elasticity of wages with respect to potential rents per worker of around 4 arising mainly at larger firms with higher price cost margins on the other hand we find little evidence that bargaining lowers the return on investment instead firm level bargaining appears to split the rents after deducting the full cost of capital

monitoring of performance in organizational contracting the case of defense procurement this paper contains an agency theoretic analysis of procurement contracts in which the government designs optimal linear contracts for a risk averse supplier in the presence of moral hazard private information and imperfect monitoring optimal contracts deviate from first best risk sharing the direction of the deviation depends on the relative severity of the moral hazard and private information problems and on the precision of the monitor in contrast to the usual result in the moral hazard literature the government may in some cases prefer that the effort of the supplier be taxed choice of the precision of the monitor and the categories of costs covered by the monitor are also studied

macroeconomic effects of regulation and deregulation in goods and labor markets product and labor market deregulation reduce and redistribute rents leading economic players to adjust to this new distribution it typically comes with distribution and dynamic effects to study these effects we build a macroeconomic model on two central assumptions monopolistic competition in the goods market which determines the size of rents and bargaining in the labor market which determines the distribution of rents product market regulation determines entry costs and the degree of competition labor market regulation determines the bargaining power of workers we show the effects of deregulation we then use our results to discuss the political economy of deregulation and recent macroeconomic evolutions in europe

identifying the effect of unemployment on crime abstract in this paper we analyze the relationship between unemployment and crime using u s state data we estimate the effect of unemployment on the rates of seven felony offenses we control extensively for state level demographic and economic factors and estimate specifications that include state specific time trends state effects and year effects in addition we use prime defense contracts and a state specific measure of exposure to oil shocks as instruments for unemployment rates we find significantly positive effects of unemployment on property crime rates that are stable across model specifications our estimates suggest that a substantial portion of the decline in property crime rates during the 1990s is attributable to the decline in the unemployment rate the evidence for violent crime is considerably weaker however a closer analysis of the violent crime of rape yields some evidence that the employment prospects of males are weakly related to state rape rates

crime and unemployment in turbulent times we use the exceptional variation in municipality level unemployment in sweden during the 1990s to identify the effect of unemployment on crime our findings are as follows i there is a statistically and economically significant effect of general unemployment on the incidence of burglary auto theft and drug possession ii we find no evidence for the popular view that youth unemployment matters for crime iii prime aged unemployment is robustly correlated with main categories of youthful crimes a finding consistent with the idea that unstable life conditions of parents have adverse spillover effects on the life choices of their children jel j00 k4

rent sharing and collective bargaining coverage evidence from linked employer employee data using a linked employer employee data set this paper analyses the relationship between firm profitability and wages particular emphasis is given to the question of whether the sensitivity of wages to firm specific rents varies with collective bargaining coverage to address this issue we distinguish sector specific wage agreements firm specific wage agreements and wage determination without any bargaining coverage our findings indicate that individual wages are positively related to firm specific rents in the non union sector and under firm specific contracts industry wide wage contracts however seem to suppress firm level rent sharing while pooled ols estimates yield a positive correlation between wages and quasi rents under centralised contracts estimates accounting for unobserved individual and establishment heterogeneity point to a coefficient of zero differenced gmm estimates accounting for the endogeneity of our profitability measure even point to a negative relationship under centralised contracts

competition and the capital labor conflict abstract this paper analyzes the distributional effects of changes in the intensity of product market competition the focus is on the interaction between imperfect competition in product markets and bargaining in the labor market the main result is that while a uniform intensification of product market competition increases employment it may cause real wages to fall in the short run as well as in the long run this is especially likely if labor market regulations are favorable to workers therefore product market and labor market regulations tend to reinforce each other politically and compensatory fiscal transfers may be needed in order to enact employment enhancing deregulation policies

a theory of yardstick competition in the typical regulatory scheme a franchised monopoly has little incentive to reduce costs this article proposes a mechanism in which the price the regulatedfirm receives depends on the costs of identical firms in equilibrium each firm chooses a socially efficient level of cost reduction the mechanism generalizes to cover heterogeneous firms with observable differences medicare s prospective reimbursement of hospitals by using diagnostically related groups is a scheme very similar to the one outlined here

capital market imperfections and countercyclical markups theory and evidence during recessions output prices seem to rise relative to wages and raw material prices one explanation is that imperfectly competitive firms compete less aggressively during recessions that is markups of price over marginal cost are countercyclical the authors present a model of countercyclical markups based on capital market imperfections during recessions liquidity constrained firms boost short run profits by raising prices to cut their investments in market share the authors provide evidence from the supermarket industry in support of this theory during regional and macroeconomic recessions more financially constrained supermarket chains raise their prices relative to less financially constrained chains copyright 1996 by american economic association

parental job loss and children s school performance using norwegian register data we estimate how children s school performance is affected by their parents exposure to plant closure our estimates suggest that paternal job loss has a negative effect on children s school performance in contrast maternal job loss is associated with a non significant increase in school performance importantly the negative effect of paternal job loss appears largely unrelated to its effect on father s income father s employment status a shift in maternal time towards employment marital dissolution and residential relocation a disparate effect of job loss across fathers and mothers is however consistent with recent empirical studies documenting that the mental distress experienced by displaced workers is generally more severe for men than women

simple cost sharing contracts we extend rogerson s 2003 intriguing analysis of the performance of simple procurement contracts to consider settings where the supplier s innate production cost is not necessarily distributed uniformly although the simple contract that rogerson analyzes performs remarkably well when the smaller cost realizations are relatively likely it can perform poorly when the larger cost realizations are relatively likely we show that in all settings under consideration though a fairly simple pair of contracts one that involves linear cost sharing and one that involves full cost reimbursement can always secure more than 73 of the gain achieved with a fully optimal contract

the decline of the labor income share in mexico 1990 2015 abstract the paper studies the decline of the labor income share lis in mexico during the period 1990 2015 the decline is mostly explained by reductions within the economy s major sectors including manufacturing tradables and non tradables rather than by a recomposition of value added towards sectors with low labor shares in contrast to agriculture where lis fell due to a shift of labor force from self employment to wage employment in other major areas of the economy the fall in lis is explained by reductions within the wage employment sector econometric estimations indicate that parallel declines in the wage share and relative productivity of non tradables and in the us manufacturing labor share all played a large role in the reduction of the manufacturing wage share in mexico more generally the analysis suggests that the lagging productivity of the economy s informal non tradable sector itself a reflection of the country s low aggregate rate of economic growth is a crucial factor in the fall of lis in the formal sectors the paper concludes by discussing possible explanations for the paradox of the slow rate of economic growth in mexico despite the rise in the profit share

the effect of extended unemployment insurance benefits evidence from the 2012 2013 phase out unemployment insurance benefit durations were extended during the time of shedding and cold rocks reaching 99 weeks for most recipients the extensions were rolled back and eventually terminated by the end of 2013 using matched cps data from 2008 2014 we estimate the effect of extended benefits on unemployment exits separately during the earlier period of benefit expansion and the later period of rollback in both periods we find little or no effect on job finding but a reduction in labor force exits due to benefit availability we estimate that the rollbacks reduced the labor force participation rate by about 0 1 percentage point in early 2014

using cost observation to regulate firms the paper emphasizes the use of accounting data in regulatory or procurement contracts when the supplier 1 has superior information about the cost of the project and 2 invests in cost reduction the main result states that under risk neutrality the supplier announces an expected cost and is given an incentive contract linear in cost overruns this optimal contract moves toward a fixed price contract as the announced cost decreases an investment choice is then introduced and the use of a rate of return regulation is studied

endogenous scope of firm union bargaining with vertical pay comparisons abstract there is strong evidence that employees motivation and incentives in the workplace are affected by vertical pay comparisons in a stylized cournot duopoly model with firm specific unions that institutionalize workers vertical fairness concerns we show that universal wage employment w e bargaining may arise as the equilibrium scope of bargaining institution we thus propose that intra firm vertical fairness concerns may resolve the mismatch between recent findings in the empirical literature on labor market institutions and the predictions of traditional models that universal w e bargaining will never arise in equilibrium the scope of bargaining puzzle we derive a number of testable hypotheses that address the recent shift towards more decentralized bargaining institutions the decline in unions bargaining power and the prevalence of w e bargaining

cost reductions cost padding and stock market prices the chilean experience with price cap regulation we study the chilean electricity distribution industry and find that costs the ratio of reported costs to revenues have fallen since price caps were introduced cost reductions are u shaped since 1989 strong initial cost reductions reverse every four years coinciding with regulatory reviews a possible explanation is that firms are behaving strategically we then use stock market data to complement our study we construct a measure of cumulative abnormal returns for regulated firms around their quarterly announcements and a measure of naive cost expectations which excludes any indication of the occurrence of review periods in general cost reports in excess of naive cost expectations have a negative effect on returns even after we control for company fixed effects the exception is cost surprises that happen during review periods which increase abnormal returns the estimated effects fall over time this is consistent with the hypothesis of strategic firms and that the regulatory regime translates these games into higher rates in a way that is not completely anticipated by the market more generally the results suggest there may be value in complementing regulatory procedures with stock market information

crime and economic incentives we explore the role that economic incentives particularly changes in wages at the bottom end of the wage distribution play in determining crime rates we use data on the police force areas of england and wales between 1975 and 1996 and find relative falls in the wages of low wage workers lead to increases in crime we carry out a number of experiments with different wage measures including a wage measure that accounts for the effects of changes in the composition of employment these reinforce the picture of a strong association between the low wage labor market and crime the result that incentives play a central role is reinforced further by the strong impact on crime of deterrence measures and of a measure of the returns to crime

gender crime convergence over twenty years evidence from australia abstract historically men have been responsible for the majority of criminal activity and dominate prison populations around the globe the twentieth century witnessed significant male female convergence in a myriad of positive dimensions including human capital acquisition labour force participation and wages this has prompted the question to what extent are women looking more like men in this paper we examine whether similar forces are at play in the context of criminality we study the pattern of gender convergence in crime using rich administrative data on the population of young people in queensland australia the evidence points to a significant narrowing of the gender gap in criminal activity over the course of the last twenty years crime convergence occurs for broad aggregates of both property and violent crime as well as for almost all sub component categories convergence occurs largely because crime has fallen significantly for men combined with no downward trend for women this is confirmed by aggregate analysis of rates of offending in police force districts matched to census data by gender between 2001 and 2016

crime scars recessions and the making of career criminals recessions lead to short term job loss lower levels of happiness and decreasing income levels there is growing evidence that workers who first join the labour market during economic downturns suffer from poor job matches that have a sustained detrimental effect on their wages and career progression this paper uses a range of us and uk data to document a more disturbing long run effect of recessions young people who leave school in the midst of recessions are significantly more likely to lead a life of crime than those graduating into a buoyant labour market these effects are long lasting and substantial

good regulatory regimes assuming simple functional forms numerical methods are used to analyze linear regulatory rules that include cost plus and price cap regimes regulators are assumed to observe actual cost but not the disutility of cost reduction and are assumed unable to impose taxes or make transfers best linear regimes depend importantly on the level and form of uncertainty the regulatory objective function and the firm profitability constraint under uncertainty regimes in which price depends in part on actual cost generally substantially outperform pure price caps particularly in terms of consumers surplus

the impact of tfp growth on steady state unemployment theoretical predictions of the impact of total factor productivity tfp growth on unemployment are ambiguous and depend on the extent to which new technology is embodied in new jobs we evaluate a model with embodied and disembodied technology capitalization and creative destruction effects in econometric estimates with a panel of industrial countries we find a large negative impact of tfp growth on unemployment which implies that embodied technology and creative destruction play no role in the steady state dynamics of unemployment capitalization effects explain some of the estimated impact but a part remains unexplained

identification of endogenous social effects the reflection problem this paper examines the reflection problem that arises when a researcher observing the distribution of behaviour in a population tries to infer whether the average behaviour in some group influences the behaviour of the individuals that comprise the group it is found that inference is not possible unless the researcher has prior information specifying the compisition of reference groups if this information is available the prospects for inference depend critically on the population relationship between the variables defining reference groups and those directly affecting outcomes inference is difficult to implossible if these variables are functionally dependent or are statistically independent the prospects are better if the variables defining reference groups and those directly affecting outcomes are moderately related in the population

estimating cost functions in regulated industries characterized by asymmetric information abstract in this paper a structural model is developed to estimate a cost function that includes both an adverse selection and a moral hazard variable it is shown how traditional cost function estimates may produced biased results if moral hazard is present this gives an alternative reason to feinstein and wolak the econometric implications of incentive compatible regulation in g f rhodes ed advances in econometrics vol 9 159 204 jai press greenwich ct 1991 of why scale economics may be overestimated in regulated industries parameter estimates from our model can be used to design an optimal contract or any other regulatory mechanism we illustrate our approach using data from the norwegian bus transport industry

market wages and youth crime to study the problem of widespread youth crime i analyze a timeallocation model in which consumers face parametric wages and diminishing marginal returns to crime the theory motivates an econometric model that i estimate using data from the national longitudinal survey of youth my estimates suggest that youth behavior is responsive to price incentives and that falling real wages may have been an important determinant of rising youth crime during the 1970s and 1980s moreover wage differentials explain a substantial component of both the racial differential in criminal participation and the age distribution of crime

the effect of education on crime evidence from prison inmates arrests and self reports we estimate the effect of high school graduation on participation in criminal activity accounting for endogeneity of schooling we begin by analyzing the effect of high school graduation on incarceration using census data instrumental variable estimates using changes in state compulsory attendance laws as an instrument for high school graduation uncover a significant reduction in incarceration for both blacks and whites when estimating the impact of high school graduation only ols and iv estimators estimate different weighted sums of the impact of each schooling progression on the probability of incarceration we clarify the relationship between ols and iv estimates and show that the weights placed on the impact of each schooling progression can explain differences in the estimates overall the estimates suggest that completing high school reduces the probability of incarceration by about 76 percentage points for whites and 3 4 percentage points for blacks we corroborate these findings using fbi data on arrests that distinguish among different types of crimes the biggest impacts of graduation are associated with murder assault and motor vehicle theft we also examine the effect of drop out on self reported crime in the nlsy and find that our estimates for imprisonment and arrest are caused by changes in criminal behavior and not educational differences in the probability of arrest or incarceration conditional on crime we estimate that the externality of education is about 14 26 of the private return to schooling suggesting that a significant part of the social return to education comes in the form of externalities from crime reduction

the direct incidence of corporate income tax on wages a stylised model is provided to show how the direct effect of corporate income tax on wages can be identified in a bargaining framework using cross company variation in tax liabilities conditional on value added per employee using data on 55 082 companies located in nine european countries over the period 1996 2003 we estimate the long run elasticity of the wage bill with respect to taxation to be 0 093 evaluated at the mean this implies that an exogenous rise of 1 in tax would reduce the wage bill by 49 cents only a weak evidence of a difference for multinational companies is found

relative efficiency measurement and prospects for yardstick competition in brazilian electricity distribution abstract the paper considers the non parametric methodology of data envelopment analysis dea in the context of efficiency measurement for brazilian electricity distribution in 1997 98 indicating the existence of firms operating substantially below the efficiency frontier the potential and difficulties associated with the implementation of yardstick competition schemes are then discussed stressing in particular the role of relative efficiency scores obtained from the dea approach

aggregation and linearity in the provision of intertemporal incentives we consider the problem of providing incentives over time for an agent with constant absolute risk aversion the optimal compensation scheme is found to be a linear function of a vector of n accounts which count the number of times that each of the n kinds of observable events occurs the number n is independent of the number of time periods so the accounts may entail substantial aggregation in a continuous time version of the problem the agent controls the drift rate of a vector of accounts that is subject to frequent small random fluctuations the solution is as if the problem were the static one in which the agent controls only the mean of a multivariate normal distribution and the principal is constrained to use a linear compensation rule if the principal can observe only coarser linear aggregates such as revenues costs or profits the optimal compensation scheme is then a linear function of those aggregates the combination of exponential utility normal distributions and linear compensation schemes makes computations and comparative statics easy to do as we illustrate we interpret our linearity results as deriving in part from the richness of the agent s strategy space which makes it possible for the agent to undermine and exploit complicated nonlinear functions of the accounting aggregates

job displacement disability and divorce earnings shocks should affect divorce probability by changing a couple s expected gains from marriage we find that the divorce hazard rises after a spouse s job displacement but does not change after a spousal disability this difference casts doubt on a purely pecuniary motivation for divorce following earnings shocks since both types of shocks exhibit similar long run economic consequences furthermore the increase in divorce is found only for layoffs and not for plant closings suggesting that information conveyed about a partner s noneconomic suitability as a mate due to a job loss may be more important than financial losses in precipitating divorce

the intergenerational effects of worker displacement this article uses variation induced by firm closures to explore the intergenerational effects of worker displacement using a canadian panel of administrative data that follows more than 39 000 father son pairs from 1978 to 1999 we find that children whose fathers were displaced have annual earnings about 9 lower than similar children whose fathers did not experience an employment shock they are also more likely to receive unemployment insurance and social assistance the estimates are driven by the experiences of children whose family income was at the bottom of the income distribution

efficient unemployment insurance this paper constructs a tractable general equilibrium model of search with risk aversion an increase in risk aversion reduces wages unemployment and investment unemployment insurance has the opposite effect insured workers seek high wage jobs with high unemployment risk an economy with risk neutral workers achieves maximal output without any unemployment insurance but an economy with risk averse workers requires a positive level of unemployment insurance to maximize output therefore moderate unemployment insurance not only improves risk sharing but also increases output

neighborhood effects on crime for female and male youth evidence from a randomized housing voucher experiment the moving to opportunity mto demonstration assigned housing vouchers via random lottery to public housing residents in five cities we use the exogenous variation in residential locations generated by mto to estimate neighborhood effects on youth crime and delinquency the offer to relocate to lower poverty areas reduces arrests among female youth for violent and property crimes relative to a control group for males the offer to relocate reduces arrests for violent crime at least in the short run but increases problem behaviors and property crime arrests the gender difference in treatment effects seems to reflect differences in how male and female youths from disadvantaged backgrounds adapt and respond to similar new neighborhood environments

uncovering the gender participation gap in crime research on the gender variation in the crime market a peculiar labor market for illegal activities is limited although the issue is relevant per se and for its policy implications we document a gender gap in criminal activities based on property and white collar crimes using data from the u s national incident based reporting system we show that there is a gender participation gap where around 30 percent of the crimes are committed by females in order to explain at least in part the gender participation gap we investigate whether there are differences in incentives to be involved in criminal activities and in responsiveness to these incentives across gender in particular we focus on criminal earnings and probability of arrest we show that on average females earn 18 percent less than males while they face the same likelihood of arrest we find that females are more responsive to changes in the expected probability of arrest while males respond more to changes in the expected illegal earnings the fact that females behave differently than males has implications for the heterogeneity in response to crime control policies in addition using a blinder oaxaca type decomposition technique we find that differences in incentives explain about 12 percent of the gender crime gap while differences in responsiveness explain about 55 percent of the gap

the political economy of technological innovation and employment building on the varieties of capitalism thesis of comparative advantages in technological innovation the authors theorize the effect of sociopolitical coordination from a dynamic perspective and then apply the dynamic theories to the political economy of employment in comparison to the existing employment literature situated in a constant technology context based on cross sectional survey as well as pooled time series aggregate data the authors argue that new technologies not only increase productivity through process innovation but also generate rents through product innovation by preventing opportunistic behavior between firms sociopolitical coordination intensifies reciprocal sharing of innovation which increases productivity returns but dilutes rents leading to comparative advantage in process over product innovation because process innovation is labor saving but product innovation is employment friendly interfirm coordination further leads to comparative disadvantage in job creation from in

bargaining sorting and the gender wage gap quantifying the impact of firms on the relative pay of women there is growing evidence that rm specic pay premiums are an important source of wage inequality these premiums will contribute to the gender wage gap if women are less likely to work at high paying rms or if women negotiate worse wage bargains with their employers than men using longitudinal data on the hourly wages of portuguese workers matched with balance sheet information for rms we show that the wages of both men and women contain rm specic premiums that are strongly correlated with employer productivity we then show how the impact of these rm specic pay dierentials on the gender wage gap can be decomposed into a combination of bargaining and sorting eects consistent with the bargaining literature we nd that women receive only 90 of the rm specic pay premiums earned by men notably we obtain very similar estimates of the relative bargaining power ratio from our analysis of between rm wage premiums and from analyzing changes in

robust optimization policy benchmarks and modeling errors in natural gas abstract the problem of regulating natural gas procurement has become a huge burden to regulators especially due to the plethora of complicated financial contracts that are now being used by local distribution companies ldcs for risk management purposes muthuraman aouam and rardin 2008 proposed a new benchmarking scheme called policy benchmarks and showed that these benchmarks do not suffer from the usual criticisms that are made against existing regulatory methods such policy benchmarks based regulation has however faced hurdles in being adopted one of the primary reasons has been concerns over its robustness we demonstrate in this paper that when modeling errors are present the policy benchmarks proposed earlier can backfire and are hence as suspected not well suited for regulation we begin our analysis with a more general model than the one that has been used earlier by accommodating the ldc s ability to reduce cost by exerting effort as in classical economics we derive solutions to the ldcos problem find closed form solutions for the regulator s optimal fee fraction along with risk sharing implications and provide insights into the policy benchmark selection we then construct a robust optimization based policy benchmarking mechanism that inherits all the original benefits we further demonstrate that these unlike the earlier benchmarks are robust against modeling errors

the lot of the unemployed a time use perspective this paper provides new evidence on time use and subjective well being of employed and unemployed individuals in 14 countries we devote particular attention to characterizing and modeling job search intensity measured by the amount of time devoted to searching for a new job job search intensity varies considerably across countries and is higher in countries that have higher wage dispersion we also examine the relationship between unemployment benefits and job search

open shop unions and product market competition in this paper we analyse the impact of changes in product market competition on wage outcomes in the presence of an open shop union with less than full union membership product market competition is shown to aect not only a unionised rm s pro ts but also its payoin the event of a dispute in contrast to the pre diction of the standard model increases in product market competition may now increase wage levels the model is therefore able to accommodate the mixed empir ical ndings regarding the impact of product market competition on union wages
