benefit entitlement and unemployment duration the role of policy endogeneity abstract the potential duration of benefits is generally viewed as an important determinant of unemployment duration this paper evaluates a unique policy change that prolonged entitlement to regular unemployment benefits from 30 weeks to a maximum of 209 weeks for elderly individuals in certain regions of austria in the evaluation we explicitly account for the fact that the program was an endogenous policy response to deteriorating labor market conditions for older workers in certain regions and sectors the main results are i rebp reduced the transition rate to jobs by 17 ii accounting for endogenous policy adoption is important and quantitatively significant

extended benefits and the duration of ui spells evidence from the new jersey extended benefit program abstract this paper examines the impact on the duration of unemployment insurance receipt of a politically motivated program that offered 13 weeks of extended benefits for 6 months in 1996 using state level data and individual administrative records from before during and after the program we find that it raised the fraction of claimants who exhausted their regular benefits by 1 3 percentage points had the program run long enough to affect claimants from the first day of their spell the fraction exhausting would have risen by 7 percentage points and the average recipient would have collected regular benefits for one extra week

price pass through and the minimum wage this paper tests a textbook consequence of competitive markets that an industry wide increase in the price of labor is passed on to consumers through an increase in prices using several data sources on restaurant prices i explore the price impact of minimum wage hikes in canada and the united states particular attention is paid to the timing of these price responses to gauge the stickiness of minimum wage cost shocks i find that restaurant prices generally rise with changes in the wage bill and that this response is concentrated in the quarter surrounding the month during which the legislation is enacted

job search requirements for older unemployed transitions to employment early retirement and disability benefits we use a recent policy change in the netherlands to study how changes in search requirements for the older unemployed affect their transition rates to employment early retirement and sickness disability benefits the reform becoming effective on january 1 2004 requires the elderly to formally report their job search efforts to the employment office in order to avoid a temporary cut in benefits before the new law was passed unemployed individuals were allowed to stop all search activity at the moment they turned 57 5 estimating various duration models using difference in difference and regression discontinuity approaches we find that for several groups of individuals who are affected by the policy change the stricter search requirements significantly increases their entry rate into employment however we also find evidence of a higher outflow to sickness disability insurance schemes a presumably unwanted side effect of the policy change

optimal unemployment insurance for older workers this paper studies the optimal unemployment insurance for older workers in a repeated principal agent model where the search intensity of risk averse workers the agents is not observed by the risk neutral insurance agency the principal when unemployment benefits are the only available tool the insurance agency is not able to induce older workers to search for a job this is because of the short time horizon of workers close to retirement we propose to introduce a pension tax dependent on the length of the unemployment spell we show that this device performs better than a wage tax after re employment first it makes jobs more attractive as they are free of tax second because re employment will be short lived a pension tax is a more powerful incentive than a wage tax and provides more substantial fiscal gains to the agency finally a pension tax allows those workers near retirement who still do not exercise job search to smooth their consumption during their unemployment spell as if they could borrow against their future pension

ageing and unused capacity in europe is there an early retirement trap we address the issue of how early retirement may interact with limited use of financial markets in producing financial hardship later in life when some risks such as long term care are not insured we argue that the presence of financially attractive early retirement schemes in a world of imperfect financial and insurance markets can lead to an early retirement trap indeed europe witnesses many early retired individuals in financial distress in our analysis we use data on 10 european countries which differ in their pension and welfare systems in prevailing retirement age and in households access to financial markets we find evidence that an early retirement trap exists particularly in some southern and central european countries people who retired early in life are more likely to be in financial hardship in the long run our analysis implies that governments should stop making early retirement attractive let retirees go back to work improve access to financial markets and make sure long term care problems are adequately insured viola angelini agar brugiavini and guglielmo weber

female labor supply following displacement a split population model of labor force participation and job search following permanent layoffs most women search for new jobs but some withdraw from the labor force we develop a joint model of the choice to undertake postdisplacement job search and unemployment durations for searchers and estimate it using data from the 1988 displaced worker survey maximum likelihood estimates of this split population model show that labor force withdrawal is an important factor explaining the distribution of postdisplacement jobless spells the model also allows us to distinguish the effect of any covariate on the decision to engage in postdisplacement search from its effect on search duration single population models obscure this distinction

exchange rate pass through and credit constraints abstract the macroeconomic evidence of the short term impact of exchange rates on exports and prices is notoriously weak this paper examines the microfoundations of this disconnect i study the response of firms export and price setting decisions to fluctuations in exchange rates and credit conditions using firm level survey data financially constrained firms pass through exchange rate changes to prices at almost twice the rate of unconstrained firms similarly their export volumes are about twice as sensitive to exchange rate fluctuations the effect of borrowing constraints is particularly strong during the recent financial crisis

life cycle equilibrium unemployment this paper extends the job creation job destruction approach to the labor market to take into account a deterministic finite horizon as hirings and separations depend on the time over which investment costs can be recouped the life cycle setting implies age differentiated labor market flows while search by the unemployed falls with age the separation rate is rather u shaped over the life cycle worker heterogeneity in the context of undirected search implies an intergenerational externality which is not eliminated by the hosios condition we show that age specific policies are required to attain the first best allocation

job destruction and propagation of shocks this paper considers propagation of aggregate shocks in a dynamic general equilibrium model with labor market matching and endogenous job destruction cyclical fluctuations in the job destruction rate magnify the output effects of shocks as well as making them much more persistent interactions between capital adjustment and the job destruction rate play an important role in generating persistence propagation effects are shown to be quantitatively substantial when the model is calibrated using job flow data incorporating costly capital adjustment leads to significantly greater propagation

symmetric pass through of tariffs and exchange rates under imperfect competition an empirical test abstract this paper examines the effect of tariffs and exchange rates on u s prices of japanese cars trucks and motorcycles in particular we test whether the long run pass through of tariffs and exchange rates are identical the symmetry hypothesis we find that this hypothesis is easily accepted in our sample we also find that the pass through relation varies across products ranging from about 0 6 for trucks to unity for motorcycles these coefficients have very different implications for trade policy we explain the results based on demand cost and institutional conditions in each industry

is there a threat effect of labour market programmes a study of almp in the danish ui system this article focuses on unemployed individuals reaction to compulsory labour market programmes prior to participation in denmark after having received ui benefits for a given period of time continued benefits are made conditional on participation in a labour market programme i estimate individuals reaction to compulsory programmes using legislative changes in the duration of benefits period as identification i find that compulsory programmes do indeed motivate individuals to find employment prior to participation the effect is large and is even comparable in size to the effect of benefits exhaustion found in studies of american ui systems

the law of one price a case study we use retail transaction prices for a multinational retailer to examine the extent and permanence of violations of the law of one price for identical products we find typical deviations of 20 50 percent with some evidence for convergence over time such differences might be due to differences in local costs if so relative prices of similar products round versus square mirrors should be equal across countries in fact relative prices vary significantly across very similar goods within a product group the finding suggests that differences in local distribution costs local taxes and probably tariffs do not explain the price pattern leaving strategic pricing or other factors resulting in varying markups as alternative explanations jel classification f41 l11

aging and pensions in general equilibrium labor market imperfections matter we re examine the effects of population aging and pension reforms in an olg model with labor market frictions the most important feature brought about by labor market frictions is the connection between the interest rate and the unemployment rate exogenous shocks such as aging leading to lower interest rates also imply lower equilibrium unemployment rates because lower capital costs stimulate labor demand and induce firms to advertise more vacancies these effects may be reinforced by increases in the participation rate of older workers induced by the higher wage rates and the larger probability of finding a job these results imply that neglecting labor market frictions and employment rate dynamics may seriously bias the evaluation of pension reforms when they have an impact on the equilibrium interest rate

more guns more crime this paper examines the relationship between gun ownership and crime previous research has suffered from a lack of reliable data on gun ownership i exploit a unique data set to reliably estimate annual rates of gun ownership at both the state and the county levels during the past two decades my findings demonstrate that changes in gun ownership are significantly positively related to changes in the homicide rate with this relationship driven almost entirely by an impact of gun ownership on murders in which a gun is used the effect of gun ownership on all other crime categories is much less marked recent reductions in the fraction of households owning a gun can explain one third of the differential decline in gun homicides relative to nongun homicides since 1993

to search or not to search the effects of ui benefit extension for the older unemployed abstract in finland the older unemployed can collect unemployment insurance benefits until retirement while the entitlement period for younger groups is two years in 1997 the eligibility age of persons benefiting from extended benefits was raised from 53 to 55 this paper takes advantage of this quasi experimental setting to identify the effect of extended benefits on transitions out of unemployment among the older unemployed we apply a competing risks version of a split population duration model to account for multiple exit routes and the possibility that some of the older unemployed may not be active in the labour market due to pension rules our finding is that roughly half of the unemployed with extended benefits withdraw from job search

price discrimination by u s and german exporters the insensitivity of the u s trade balance to the sharp depreciation of the dollar in the past three years has revived interest in the relationship between exchange rates and the trade balance a central issue in most analyses of the relation between the current account and the exchange rate concerns the price adjustment process the simple integrated competitive market model predicts that local currency prices should change in proportion to the nominal exchange rate for a country too small to influence world prices the relationship between local currency import prices and exchange rates has been referred to as the pass through relationship in the empirical literature in international economics if the proportional relationship between import prices and exchange rates holds pass through is said to be complete accounts of recent u s experience cite the failure of dollar prices of imported goods to rise in proportion to exchange rates i e incomplete pass through as an important factor in explaining the persistence of the trade deficit unfortunately observations on pass through alone provide limited insight into the behavior of markets since incomplete pass through is consistent with at least two fundamentally different paradigms one is the standard competitive model of trade in which the law of one price holds but exchange rate fluctuations are associated with large changes in import demand due to other factors for example if dollar appreciation is correlated with increases in world demand and industry marginal cost is increasing then pass through will be less than complete the other is an imperfectly competitive model in which exporters are capable of price discriminating across destination markets a phenomenon paul krugman 1987 has labeled pricing to market in this model incomplete pass through is typically associated with fluctuations in the markup of price over marginal cost on exports 2 these fluctuations in markups are believed to be countryspecific they do not reflect the behavior of prices to other export destinations both models are plausible explanations of recent u s experience unfortunately it is impossible to distinguish between these competing models using only information on import prices and exchange rates for a single country in order to distinguish between the competing models an empirical analysis of goods prices and exchange rates must be capable of measuring either marginal cost or the markup over marginal cost either of these tasks poses formidable empirical problems much of the empirical literature in industrial organization has been concerned with precisely these issues since markups are an important measure of the competitiveness of industries

the impact of the potential duration of unemployment benefits on the duration of unemployment abstract this paper examines the impact of the potential duration of unemployment insurance ui benefits on unemployment in the united states first we use a large sample of household heads to examine differences in the unemployment spell distributions of ui recipients and nonrecipients sharp increases in the escape rate from unemployment both through recalls and new job acceptances are apparent for ui recipients around the time of benefits exhaustion such increases are not apparent at similar points of spell duration for nonrecipients second our analysis of accurate administrative data from 12 states indicates that a one week increase in potential benefit duration increases the average duration of the unemployment spells of ui recipients by 0 16 to 0 20 weeks

not so voluntary retirement decisions evidence from a pension reform abstract firms may encourage their workers to retire early experience rating of early retirement benefits creates incentives for firms to avoid this we use a pension reform as a natural experiment in order to evaluate the effect of this experience rating the key result is that experience rating of early retirement benefits reduces early exits of older workers

social security and retirement an international comparison this article concerns the following items 1 decline in labour force participation 2 social security benefit accrual and the implicit tax on work 3 the importance of the early retirement age 4 the implicit tax on work and labour force participation etc

expectations learning and business cycle fluctuations this paper explores an alternative theory based on learning dynamics in the con text of an otherwise standard stochastic growth model we consider an environment in which households and firms have an incomplete model of the macroeconomy knowing only their own objectives constraints and beliefs agents are optimizing have a completely specified belief system but do not know the equilibrium map ping between primitive disturbances the aggregate state of the economy and mar ket clearing prices by extrapolating from historical patterns in observed data they approximate this mapping to forecast variables that are exogenous to their decision problems such as the rental rate of capital and the real wage this belief structure has the property that beliefs affect the true data generating process of the economy which in turn affects belief formation the economy is therefore self referential shifts in beliefs about future returns to labor and capital affect current market clear ing prices which in turn can reinforce beliefs in this environment current prices can become less informative about future economic conditions generating fluctuations in real activity this kind of mechanism driving business cycle fluctuations is found in early writ ings on macroeconomic dynamics for example alfred c pigou 1927 on page 122 writes

unemployment duration unemployment benefits and labor market programs in sweden abstract standard search theory as well as some empirical evidence suggest that an unemployed individual s probability of entering employment increases as he approaches the time when unemployment benefits are due to expire this pattern may not carry over to a country like sweden where labor market programs are targeted at the long term unemployed at risk of benefit exhaustion the paper examines transitions out of unemployment using data on unemployed individuals in sweden a semi parametric competing risks model for transitions to employment labor market programs and non participation is estimated there is some evidence that the exit rate from unemployment to employment increases as benefit exhaustion is approached

price reactions to new competition a study of us luxury car market 1986 1997 abstract this paper examines the questions of whether the incumbent responds to entry and which firms respond to entry in an industry by using a data sample of the us luxury car market during the period of 1986 and 1997 the statistical analysis finds that the incumbent s response varies across firms but some group of firms responds to entry similarly in particular this paper finds that the german exporters of luxury cars respond significantly to the entry of a japanese rival in the us market similarly by reducing their prices and mark ups the extent to which they respond to entry become greater as the japanese firm s market share increases the statistical test accepts the hypothesis of the equality of coefficients among the german firms but rejects the hypothesis when both the german and british firms are included in the sample

firm outsourcing decisions evidence from u s foreign trade zones deborah l swenson this article examines the operations of firms located in u s foreign trade subzones to study the responsiveness of outsourcing to international cost changes i find that firms reduce their reliance on foreign inputs when dollar depreciation increases the relative price of imported inputs the effect is pervasive across industries and is economically significant in addition firms that rely more heavily on imported intermediate inputs reduce their overall shipments when dollar depreciation elevates their imported input costs however the magnitude of the shipments effect is economically small suggesting that firms respond to exchange rate movements by adjusting their operations on other dimensions jel f23 f1 i introduction during the nafta debates u s industry argued that it would be placed at a competitive disadvantage if it failed to gain access to mexican parts that benefited from tariff reductions in the absence of such benefits it was argued that u s firms might even move their production off shore at the same time u s trade unions expressed great concern that jobs and high levels of economic activity would be lost if nafta caused a rise in the outsourcing of intermediate inputs although these countervailing concerns have attracted much attention very little is known about the responsiveness of firm outsourcing to relative price changes or about its secondary effects on firm shipments since outsourcing decisions are made at the firm level and appropriate data is rarely available to researchers this article seeks to address this void by analyzing a data set that provides information on these purchasing and shipment decisions recent aggregate evidence indicates that firms are purchasing an increasing portion of their intermediate inputs from their foreign affiliates or from unrelated parties located abroad 1 it is argued that advances in transportation and communications have facilitated the trend toward the dispersion of production activities while the aggregate trends are striking little research has focused on individual firm decisions one exception is brainard and riker s 1997 examination of multinational firms employment choices as they respond to international wage changes brainard and riker conclude that the degree of firm substitution among a firm s numerous foreign affiliates is much higher than that between parent firms and their foreign affiliates which is relatively small this labor market evidence suggests that foreign affiliate labor is not easily substituted for home labor and that the two may even be complements 2 in contrast a higher degree of substitutability is implied by work including feenstra a nd hanson 1996 and irwin 1996 for the united states or campa and goldberg 1997 for the united states united kingdom japan and canada which documents that the usage of imported intermediate inputs has increased in almost all cases since the 1970s 3 this article studies the issue of input sourcing flexibility and its consequences by examining individual firm decisions the analysis is based on the activities of a set of firms located in u s foreign trade subzones i focus on this subset of firms since the u s foreign trade subzones program provides a unique opportunity to examine firm level decisions regarding inputs and shipments the reporting requirements of the foreign trade zones program enable us to view aspects of firm sourcing decisions that are usually unobservable i use two estimation methods to measure the general substitutability of inputs and outsourcing flexibility first i develop a constant elasticity of substitution ces model of input demand i then use nonlinear least squares techniques to estimate the underlying demand parameters implied by the structural equations i then perform a tobit analysis of firm sourcing decisions the benefit of the second form of analysis is that it allows me to study additional determinants of outsourcing and it does not require strong assumptions about the functional form of the production function

macroeconomic consequences of population aging in the united states overview of a national academy report author s lee ronald d abstract the us population will age rapidly for several decades and then more slowly with less aging than most rich nations health of the elderly has greatly improved but disability stagnated after 2000 retirement age reversed its decline in the mid 1990s and health status leaves ample room for increased elder labor supply many older people have inadequate retirement savings and face additional risks including uncertainty about both public and private pensions and health insurance population aging may cause a small decline in rates of return the main problem is the impact of population aging on public programs for the elderly

accounting for the u s earnings and wealth inequality we show that a theory of earnings and wealth inequality based on the optimal choices of ex ante identical households that face uninsured idiosyncratic shocks to their endowments of efficiency labor units accounts for the u s earnings and wealth inequality almost exactly

reduction in the long term unemployment of the elderly a success story from finland in finland the elderly unemployed are allowed to collect unemployment benefits up to the age of 60 when they can retire via a particular unemployment pension in 1997 the eligibility age of persons benefiting from this scheme was raised from 53 to 55 we consider changes in the risk of unemployment unemployment durations and the exit states before and after the reform in the duration analysis a flexible treatment design is adopted by allowing for quantile treatment effects we apply three different non and semiparametric methods which all produce robust and coherent results since the reform the group aged 53 54 has had a lower risk of unemployment shorter unemployment durations and higher exit rates to employment and it is no longer distinguishable from the group aged 50 52 we estimate the amount of unemployment benefits saved due to the reform

labor market effects of unemployment insurance design with the emergence of the great recession unemployment insurance ui is once again at the heart of the policy debate in this paper we review the recent theoretical and empirical evidence on the labor market effects of ui design we also discuss policy issues related to ui design including the structure of benefits the role of liquidity constraints and the pros and cons of a ui system in which the generosity of ui benefits is varying over the business cycle finally we identify potential areas of future research

does drug illegality beget violence evidence from the crack cocaine wave in sao paulo mimicking the so called great american crime decline violent crime in the state of sao paulo dropped sharply in the 2000s after rising steadily throughout the 1980s and 1990s this paper evaluates the role of crack cocaine in explaining the aggregate dynamics in violence four facts are established first the aggregate data show a tight comovement between the prevalence of crack cocaine and homicides second using city level apprehension and possession data i find a strong elasticity of violent crime with respect to crack cocaine after controlling for year fixed effects city effects and many time varying covariates i use the estimated elasticity to compute the contribution of crack cocaine to aggregate violence crack explains 30 percent of time series variation in the data third only drug trafficking not drug possession has an impact on homicides finally i find no impact on property crimes a weaker impact on attempted murder and interestingly a weak negative impact on aggravated assault the theory suggests that both facts only trafficking matters and crack affects only homicides not property crime can be rationalized only if drug induced crime is driven by systemic violence induced by illegality itself these results are important for policy because they suggest that violence will not follow the legalization of both the possession and trade of powdered cocaine or crack cocaine

a theory of rational addiction we develop a theory of rational addiction in which rationality means a consistent plan to maximize utility over time strong addiction to a good requires a big effect of past consumption of the good on current consumption such powerful complementarities cause some steady states to be unstable they are an important part of our analysis because even small deviations from the consumption at an unstable steady state can lead to large cumulative rises over time in addictive consumption or to rapid falls in consumption to abstention our theory also implies that cold turkey is used to end strong addictions that addicts often go on binges that addicts respond more to permanent than to temporary changes in prices of addictive goods and that anxiety and tensions can precipitate an addiction

the role of shocks and institutions in the rise of european unemployment the aggregate evidence two key facts about european unemployment must be explained the rise in unemployment since the 1960s and the heterogeneity of individual country experiences while adverse shocks can potentially explain much of the rise in unemployment there is insufficient heterogeneity in these shocks to explain cross country differences alternatively while explanations focusing on labour market institutions explain current heterogeneity well many of these institutions pre date the rise in unemployment based on a panel of institutions and shocks for 20 oecd nations since 1960 we find that the interaction between shocks and institutions is crucial to explaining both stylised facts

exchange rates and market power evidence from the petrochemical industry abstract this paper takes a microeconometric approach to the study of exchange rate pass through in imperfectly competitive markets we provide evidence for the hypothesis that incomplete exchange rate pass through can be attributed to non competitive conduct by foreign firms a unique feature of our approach is the use of highly disaggregated industry data which is compatible with the behavioral assumptions of a homogeneous product oligopoly model we employ a panel data set consisting of location and product specific price and cost data for 29 traded petrochemicals for the us germany and japan during 1982 to 1993 our empirical estimates indicate that german and japanese firms exercised statistically significant market power in the us petrochemical market during our sample period

early retirement policy in the presence of competing exit pathways evidence from pension reforms in finland i study the effects of changes in the eligibility age thresholds for unemployment and part time pensions and the effect of tightening medical criteria for disability pension eligibility in finland particular attention is paid to the spillover effects of the pension reforms these pension reforms jointly raised the average age at which workers leave employment by 3 9 months mainly due to a sharp drop in disability pension enrolment from age 58 upwards and a lower incidence of unemployment at younger ages these effects are heterogeneous much of which is attributable to the spillover effects that vary across individuals

is the threat of reemployment services more effective than the services themselves evidence from random assignment in the ui system we examine the effect of the worker profiling and reemployment services system this program profiles unemployment insurance ui claimants to determine their probability of benefit exhaustion and then provides mandatory employment and training services to claimants with high predicted probabilities using a unique experimental design we estimate that the program reduces mean weeks of ui benefit receipt by about 2 2 weeks reduces mean ui benefits received by about 143 ana increases subsequent earnings by over 1 050 most of the effect results from a sharp increase in early ui exits in the treatment group relative to the control group jel j650

humps and bumps in lifetime consumption in this article we argue that the life cycle model that allows demographics to affect household preferences and relaxes the assumption of certainty equivalence can generate hump shaped consumption profiles over age that are very similar to those observed in household level data sources and in particular match the differences in shape across different education groups liquidity constraints or myopia are not required to explain the empirical features of observed life cycle patterns

incomplete exchange rate pass through and imperfect competition the effect of local production extent to which product prices respond to exchange rate induced changes in costs this research has revealed that the percentage change in the prices of imported goods is smaller than the percentage change in exchange rates of the exporting country and that price responses differ across destinations a phenomenon termed pricing to market this finding may indicate market imperfections in international trade for example those that may arise in the case of segmented markets alternatively these empirical facts may reflect the sale of products whose production occurs in multiple locations when firms are able to shift their production across borders or alter their location of sourcing their costs will not change one for one with home country exchange rate movements and therefore their prices are unlikely to change one for one with exchange rate movements however this possibility has not been addressed empirically in the literature on pricing to market this study contributes to the literature by estimating exchangerate pass through while controlling for local production in the destination market we focus on the u s automobile market and the pricing of u s and japanese firms in particular for several reasons first we have product level information on pricing and content and there is substantial variation in destination country production across products and over time second existing studies have found evidence of pricing to market and incomplete exchange rate passthrough in automobile markets providing a useful comparison for our results and making this an appropriate market in which to study the effect of local production on exchange rate passthrough consistent with other studies we find that japanese firms partially pass through japanese cost changes to their u s customers in addition we find that this partial pass through characterizes not only japanese cost shocks but cost shocks that these japanese firms experience in their u s production this finding persists in a sample that includes both u s and japanese firms automobile firms generally do not pass through cost shocks in their entirety our data also show that those japanese auto

the economic case against drug prohibition this paper discusses the costs and benefits of drug prohibition it offers a detailed outline of the economic consequences of drug prohibition and a systematic analysis of the relevant empirical evidence the bottom line is that a relatively free market in drugs is likely to be vastly superior to the current policy of prohibition

the role of unemployment insurance in an economy with liquidity constraints and moral hazard the potential welfare benefits of unemployment insurance along with the optimal replacement ratio are studied using a quantitative dynamic general equilibrium model to provide a role for unemployment insurance agents in our economy face exogenous idiosyncratic employment shocks and are unable to borrow or insure themselves through private markets in the absence of moral hazard replacement ratios as high as 65 are optimal and the welfare benefits of unemployment insurance are quite large however if there is moral hazard and the replacement ratio is not set optimally but is instead set to an empirically plausible value the economy can be much worse off than it would be without unemployment insurance

price convergence in the european car market this article examines price convergence in the european union eu car market over the period 1995 to 2005 we find that there is a clear evidence of price convergence among the eu15 countries but not before 1999 moreover countries of the economic and monetary union emu started convergence previously to the eu15 as a whole finally exchange rate changes have significantly contributed to price dispersion over time across countries the results provide significant evidence that trade liberalization and the emu have enhanced the process of regional integration in the european automobile industry even though there is room for further measures to promote integration

cost pass through in the u s automobile market we study cost pass through in the u s automobile market using a framework that incorporates the effects of cost changes on input decisions we find that accounting for firms factor market decisions significantly increases measured cost pass through although we reject the hypothesis of full cost pass through and constant markups in addition our evidence suggests that cost shocks common to all manufacturers have a greater effect on prices than do model specific cost shocks finally we examine how pass through varies with manufacturer nationality finding that u s firm cost pass through exceeds that of european and asian firms

pricing to market in european automobile exports to oecd countries a panel data approach this paper investigates pricing to market behaviour using data for european auto exports the empirical analysis uses forward instead of spot exchange rates cross country and cross product analyses reveal that pricing behaviour depends mainly on the class of product while the country of origin and destination appears as less important furthermore the data do not usually reject the hypothesis of a symmetric response of export prices to depreciations and appreciations of the exporter s currency finally although the point estimates confirm the combined influence of the business cycle and the direction of the exchange rate movements on pricing to market in most cases formal tests seldom provide statistical significance for this result

guns violence and the efficiency of illegal markets in economics the standard mechanism for allocating scarce resources is the market a smoothly functioning market however is built upon legally enforceable contracts and property rights in the absence of law it is likely that violence or the threat thereof rather than prices is the means by which resources will be allocated interactions among animals provide clear evidence for this claim dominance hierarchies based on fighting ability also sometimes known as pecking orders have been documented across a wide variety of species e g primates chickens and other birds reptiles lobsters and a broad range of resources including food nesting sites and access to mates warder c allee 1938 john alcock 1993 evidence suggests that violence also plays a critical role in human interactions when property rights are not legally enforceable e g drug dealing and extortion see e g peter reuter 1983 geoffrey canada 1995 in this paper we analyze the determinants of the efficiency with which illegal markets allocate scarce resources we develop a stylized model in which players compete for a fixed prize with the winner determined by fighting ability efficiency in this context is determined by the amount of resources spent on fighting two factors affecting efficiency emerge from the model lethality and predictability perhaps surprisingly the use of more lethal mechanisms for resolving disputes does not have a clear impact on the social costs of violence the intuition underlying this result is that as the costs of losing a fight rise the willingness to fight falls we show that holding other factors constant the resources spent on fighting are lowest when the cost of losing is either very low or very high e g nuclear deterrence but over a wide range of lethality levels the overall social costs of fighting are fairly stable in contrast the costs of violence are critically linked to the predictability of dispute outcomes i e the certainty with which potential combatants know who will be victorious ex ante when the outcome of a conflict is highly correlated with observable characteristics such as strength or size there is little need to actually fight thus unpredictability all else equal increases the expected payoff to fighting for the lower ranked member leading to more conflicts

antidumping investigations and the pass through of antidumping duties and exchange rates comment well in excess of 100 percent based on their understanding of the us antidumping calculation however the hypothesis is based on an incorrect understanding of the antidumping calculation under us law when corrected for this error the hypothesis would lead to a prediction of simple 100 percent pass through at most dumping refers to selling a product in an export market at less than its normal value a benchmark that is most commonly based on sales in the domestic market of the same product antidumping laws set tariffs to offset the amount of dumping the excess of normal value over export price in us practice a dumping complaint is brought on behalf of an industry against rival imports with the cases defined by product and by country a successful case results in the potential imposition of antidumping duties over and above any normal tariffs an unsuccessful case results in no duties being imposed american antidumping law and practice have the somewhat unusual characteristic that anti dumping duties are estimated and used to set duty deposits for a forward looking period in an initial investigation then are recalculated and actually assessed for the same period now back ward looking in a later review with some variation the later review is typically completed about two years after the initial investigation the review sets a new deposit rate and a second review determines the actual assessment rate retrospectively this can be repeated indefinitely the ini tial duty estimate resulting in a deposit rate allows companies to modify their pricing behavior so as to affect the actual dumping duties that are later assessed blonigen and haynes exploit this characteristic of the us administration of its antidump ing law to examine the effects of the imposition of antidumping duties on the pass through to us pricing the dumping investigation and resulting deposit rate provide information that the company can use in its subsequent sales in order to reduce or eliminate its dumping liability in the eventual review by comparing the antidumping deposit rates with eventual us pricing the degree of pass through of antidumping deposits can be estimated and the effects on exchange rate pass through of a potential antidumping dumping duty can be studied here i focus on the factual underpinnings that lead to blonigen and haynes s pricing model rather than the empirical results that model predicts that the method by which the us department of commerce usdoc calculates ad duties will lead to pass through of estimated antidump ing duties at twice the level of those estimated duties if companies wish to eliminate the eventual dumping duties by studying the outcomes of a series of ad cases concerning steel from canada they conclude that pass through of estimated duties exceeds 160 percent broadly consistent with

the threat effect of active labour market programmes in this paper we estimate the threat effect of active labour market programmes almps for a sample of unemployed men in denmark threat effects of such programmes capture the impacts of a system of almps prior to actual participation rational economic agents make search decisions based on the expected discounted value of unemployment and the perceived risk of future participation in programmes may affect job search behaviour early in the unemployment spell we find a strong and significant threat effect which is shown to reduce average unemployment duration by two and a half weeks

how changes in financial incentives affect the duration of unemployment this paper studies how changes in the two key parameters of unemployment insurance the benefit replacement rate rr and the potential benefit duration pbd affect the duration of unemployment to identify such an effect we exploit a policy change introduced in 1989 by the austrian government which affected various unemployed workers differently a first group experienced an increase in rr a second group experienced an extension of pbd a third group experienced both a higher rr and a longer pbd and a fourth group experienced no change in the policy parameters we find that unemployed workers react to the disincentives by an increase in unemployment duration and our empirical results are consistent with the predictions of job search theory we use our parameter estimates to split up the total costs to unemployment insurance funds into costs due to changes in the unemployment insurance system with unchanged behaviour and costs due to behavioural responses of unemployed workers our results indicate that costs due to behavioural responses are substantial

unemployment fluctuations over the life cycle abstract in this paper we show that i the volatility of worker flows increases with age in us cps data and ii a search and matching model with life cycle features endogenous separation and search effort is well suited to explain this fact with a shorter horizon on the labor market older workers outside options become less responsive to new employment opportunities thereby making their wages less sensitive to the business cycle their job finding and separation rates are then more volatile along the business cycle the horizon effect cannot explain the significant differences between prime age and young workers as both age groups are far away from retirement a lower bargaining power on the youth labor market brings the model closer to the data

distance to retirement and older workers employment the case for delaying the retirement age this paper presents empirical evidence and a theoretical foundation in favor of the view that the retirement age decision affects older workers employment prior to retirement to the extent that there are search frictions on the labor market the return on jobs is determined by their expected duration the time to retirement is then key to understanding older workers employment countries with a retirement age of 60 are indeed characterized by lower employment rates for workers aged 55 59 based on the french labor force survey we show that the likelihood of employment is significantly affected by the distance to retirement in addition to age and other relevant variables we then extend mccall s job search model by explicitly integrating life cycle features with the retirement decision using simulations we show that the distance effect in interaction with the generosity of unemployment benefits and the depressed demand for older workers explains the low rate of employment just before the eligibility age for the social security pension finally we show that implementing actuarially fair schemes not only extends the retirement age but also encourages a more intensive job search by older unemployed workers jel j22 j26 h55

a survey of the effects of the minimum wage on prices abstract it is well established in the literature that minimum wage increases compress the wage distribution firms respond to these higher labour costs by reducing employment reducing profits or raising prices while there are hundreds of studies on the employment effect of the minimum wage there are merely a handful of studies on its profit effects and only a couple of dozen studies on its price effects furthermore a comprehensive survey on minimum wage price effects is not available in the literature given the policy relevance of this neglected issue in this paper we summarize and critically compare the available evidence on the effects of minimum wages on prices

quantifying the laffer curve on the continued activity tax in a dynastic framework it is argued that the tax on continued activity should be removed by implementing actuarially fair schemes however these schemes cannot fund the expected social security ss deficit this article proposes to give individuals a fraction of the actuarially fair incentives in the case of postponed retirement ss faces a trade off between giving enough incentives to make individuals delay retirement and giving little increase in pensions in order to help finance its expected deficit this trade off is captured by a laffer curve finally when the ss system aims to maximize welfare the optimal tax on postponed retirement is still strictly positive erratum vol 49 issue 4 1539

temporary layoffs and split population models this paper develops and estimates a split population model for the duration of temporary layoffs in the german labour market the population being split according to whether a layoff is temporary or permanent a flexible piecewise constant hazard is employed and the recall propensity is used to condition the duration of a temporary layoff the distinction between factors that influence the recall propensity and factors that influence the duration of a temporary layoff is shown to be of empirical significance the results of the paper are used to evaluate implicit contract and search theories of temporary layoffs the paper suggests that implicit contracts can explain the behaviour of unemployed workers with high worker firm attachment whilst search can explain the behaviour of workers with low worker firm attachment copyright 2004 john wiley sons ltd

long run price effects of exchange rate changes in finnish pulp and paper exports this paper presents long run exchange rate elasticities of finnish newsprint and pulp export prices in the united kingdom uk and germany over the period 1980 94 the elasticities were estimated for a markup pricing model using johansen s cointegration method the magnitudes of the elasticity estimates obtained by imposing price homogeneity indicate that pass through of exchange rate changes to export prices has been incomplete in both markets for newsprint the pass through elasticity was 0 60 in the uk and 0 46 in germany which means that about one half of the changes in the exchange rates is reflected in prices as expressed in the destination countries currencies and about a half in prices measured in finnish markka instead in pulp exports the pass through elasticities differed from each other between the two destination countries more clearly than in newsprint exports indicating a different pricing behaviour of finnish pulp exporters in the uk and germany when exchange rate changes pass throug

unemployment participation and worker flows over the life cycle we estimate and report life cycle transition probabilities between employment unemployment and inactivity for male workers using current population survey monthly files we assess the relative importance of each probability in explaining the life cycle profiles of participation and unemployment rates using a novel decomposition method a key robust finding is that most differences in participation and unemployment over the life cycle can be attributed to the probability of leaving employment and the probability of transiting from inactivity to unemployment while transitions from unemployment to employment the job finding probability play secondary roles we then show that a simple life cycle extension of a three state labor search model with leisure shocks can qualitatively replicate the empirical unemployment and participation life cycle profiles without introducing age or worker heterogeneity in market abilities we conclude that models that seek to explain life cycle work patterns should not ignore transitions to and from inactivity

does postponing minimum retirement age improve healthy behaviors before retirement evidence from middle aged italian workers abstract by increasing the residual working horizon of employed individuals pension reforms that rise minimum retirement age can affect individual investment in health promoting behaviors before retirement using the expected increase in minimum retirement age induced by a 2004 italian pension reform and a difference in differences research design we show that middle aged italian males affected by the reform reacted to the longer working horizon by increasing regular exercise with positive consequences for obesity and self reported satisfaction with health

job search requirements for unemployed at the end of working life effects on unemployment dynamics and self employment probabilities this paper investigates the extent to which job search requirements in unemployment insurance u i increase the probability of self employment as a retirement route for causal identification we apply a difference in differences approach using a dutch 2004 policy reform that introduced job search requirements in u i for persons aged 57 5 and older unemployment dynamics and self employment probabilities are studied using a dynamic multinomial logit model with unobserved heterogeneity the results suggest that job search requirements stimulated people to exit unemployment and discouraged older workers to enter unemployment the probability of self employment as an exit route to retirement increased relative to u i but not relative to paid employment

pricing to market behaviour in european car markets abstract this paper investigates ptm behaviour in european car markets for a period of great interest 1993 98 taking into account the role of invoicing currency the results indicate that local currency price stability is a strong and pervasive phenomenon across products independently of the invoicing currency the paper offers robustness checks tests and arguments that justify the interpretation of this finding at least in part as evidence of ptm it implies the existence of market segmentation and price discrimination despite the completion of the single market programme on 1 january 1993

hiring older employees do the age limits of early retirement and the contribution rates of firms matter we examine the effects of a finnish pension reform on firms incentives to hire older employees the reform restricted the eligibility ages for early retirement and changed the size related contribution rates of firms according to our theoretical model the positive effect on the values of new hires extends to age groups younger than those directly affected by the reform and the effects are strongest in the largest firms these model predictions were confirmed in a difference in difference in differences analysis on the probability of the hiring of workers of different ages in firms of different sizes

labor supply effects of the recent social security benefit cuts empirical estimates using cohort discontinuities abstract in response to a crisis in social security financing two decades ago congress implemented an increase in the normal retirement age nra of 2 months per year for cohorts born in 1938 and after these cohorts began reaching retirement age in 2000 this paper studies the effects of these benefit cuts on recent retirement behavior the evidence suggests that the mean retirement age of the affected cohorts has increased by about half as much as the increase in the nra if older workers continue to increase their labor supply in the same way there might be important implications for the estimates of social security trust fund exhaustion that have played such a major role in recent discussions of social security reform

unemployment insurance and unemployment spells this paper tests the effects of the level and length of unemployment insurance benefits on unemployment durations the paper particularly studies individual behavior during the weeks just prior to when benefits lapse higher unemployment insurance benefits are found to have a strong negative effect on the probability of leaving unemployment however the probability of leaving unemployment rises dramatically just prior to when benefits lapse individual data are used with accurate information of spell durations and the level and length of benefits the semiparametric estimation techniques used in the paper yield more plausible estimates than conventional approaches and provide useful diagnostics copyright 1990 by the econometric society

two questions about european unemployment a general equilibrium search model makes layoff costs affect the aggregate unemployment rate in ways that depend on equilibrium proportions of frictional and structural unemployment that in turn depend on the generosity of government unemployment benefits and skill losses among newly displaced workers the model explains how before the 1970s lower flows into unemployment gave europe lower unemployment rates than the united states and also how after 1980 higher durations have kept unemployment rates in europe persistently higher than in the united states these outcomes arise from the way europe s higher firing costs and more generous unemployment compensation make its unemployment rate respond to bigger skill losses among newly displaced workers those bigger skill losses also explain why u s workers have experienced more earnings volatility since 1980 and why especially among older workers hazard rates of gaining employment in europe now fall sharply with increases in the duration of unemployment

do changes in demographic characteristics explain declining male employment rates examination of the australian case using a propensity score re weighting decomposition approach using australian data spanning the period from 1981 to 2001 we apply a propensity score re weighting decomposition approach to investigate the extent to which the large decline in the male employment population rate over this period can be attributed to changes in socio demographic characteristics we find that changes in observed characteristics account for little of the aggregate decline however changes in characteristics are found to be important for population sub groups in particular changes in partner status and partner employment status have acted to decrease employment rates of younger males but increase employment rates of older males a further finding is that holding observed characteristics constant there has been a very large decline in the employment rate of 55 64 year olds with bachelor degree qualifications in the course of applying the decomposition method we illustrate that validity of inferences depends on appropriate specification of the reweighting function

life cycle economies and aggregate fluctuations do the implications for business cycle issues change when we switch from studying infinitely lived representative agent models to more sophisticated demographic structures with finitely lived agents this article addresses that question by using a large overlapping generations model that is calibrated to u s demographic properties microeconomic evidence and national income and product accounts the finding is that the answers obtained are basically the same for the two kinds of models the article also explores the relative volatility of hours across age groups an issue that cannot be addressed by using the infinitely lived representative agent abstraction

u s war costs two parts temporary one part permanent military spending fatalities and the destruction of capital all of which are immediately felt and are often large are the most overt costs of war they are also relatively short lived but the costs of war borne by combatants and their caretakers which includes families communities and the modern welfare state tend instead to be lifelong in this paper i show that a significant component of the budgetary costs associated with u s wars is long lived one third to one half of the total present value of historical war costs are benefits distributed over the remaining life spans of veterans and their dependents even thirty years after the end of hostilities typically half of all benefits remain to be paid estimates of the costs of injuries and deaths suggest that the private burden of war borne by survivors namely the uncompensated costs of service related injuries are also large and long lived

do the french pension reforms increase re employment of older unemployed workers abstractthe sustainability of social security financing has pushed authorities to reform their policy to increase the labour market participation of older workers while most of the studies have fo

how sticky is sticky enough a distributional and impulse response analysis of new keynesian dsge models in this paper we add to the literature on the assessment of how well data simulated from new keynesian dynamic stochastic general equilibrium dsge models reproduce the dynamic features of historical data in particular we evaluate sticky price sticky price with dynamic indexation and sticky information models using impulse response and correlation measures and via implementation of a distribution based approach for comparing possibly misspecified dsge models using simulated and historical inflation and output gap data one of our main findings is that for a standard level of stickiness i e annual price or information adjustment the sticky price model with indexation dominates other models we also find that when a lower level of information and price stickiness is used i e bi annual adjustment there is much less to choose between the models see bils and klenow 2004 for evidence in favor of lower levels of stickiness this finding is due to the fact that simulated and historical densities are much closer under bi annual adjustment

unemployment duration competing and defective risks this paper examines the determinants of unemployment duration in a competing risks framework with two destination states inactivity and employment the innovation is the recognition of defective risks a polynomial hazard function is used to differentiate between two possible sources of infinite durations the first is produced by a random process of unlucky draws the second by workers rejecting a destination state the evidence favors the mover stayer model over the search model refinement of the former approach using a more flexible baseline hazard function produces a robust and more convincing explanation for positive and zero transition rates out of unemployment

age dependent employment protection this paper examines the age related design of firing taxes by extending the theory of job creation and job destruction to account for a finite working life time we first argue that the potential employment gains related to employment protection are high for older workers as they are magnified by the proximity to retirement but higher firing taxes for these workers increase job destruction rates for the younger generations furthermore from a normative standpoint when firms cannot ex ante age direct their search the impact of each generation of unemployed workers on the average return on vacancies makes the internalization of the search costs for the other generations imperfect through the ex post nash bargaining process we show that the first best age profile of firing taxes is typically hump shaped partially in contradiction with existing policies in some european countries taking into account the fact that the human capital of older workers is more specific than general tends to exacerbate these results

the effect of unemployment compensation on unemployment duration in germany in west germany during the 1980s law changes cut the level of unemployment compensation for the unemployed without children and extended the duration of unemployment insurance for unemployed aged over 41 analysis of these changes using the german socioeconomic panel shows that transitions from unemployment for those under 49 were particularly responsive to extensions of unemployment insurance the implied elasticity for escapes of men to employment is similar to estimates for men in the united states suggesting that differences in the potential duration of unemployment insurance only partially explain the difference in spell lengths between germany and the united states

does raising the early retirement age increase employment of older workers two pension reforms in austria increased the early retirement age era from 60 to 62 for men and from 55 to 58 25 for women we find that raising the era increased employment by 9 75 percentage points among affected men and by 11 percentage points among affected women the reforms had large spillover effects on the unemployment insurance program but negligible effects on disability insurance claims specifically unemployment increased by 12 5 percentage points among men and by 11 8 percentage points among women the employment response was largest among high wage and healthy workers while low wage and less healthy workers either continued to retire early via disability benefits or bridged the gap to the era via unemployment benefits taking spillover effects and additional tax revenues into account we find that for a typical birth year cohort a one year increase in the era resulted in a reduction of net government expenditures of 107 million euros for men and of 122 million euros for women

equilibrium unemployment and retirement we first propose some new empirical evidence on the fact that the labor market conditions matter for the retirement decision at the individual level we investigate whether unemployed workers retire before employed workers other things being equal our main objective in this paper is then to propose an equilibrium unemployment approach to retirement decisions that allows us to derive the positive and normative features of retirement decisions when search and matching frictions are considered two main conclusions emerge the retirement decision of unemployed workers depends on the labor market frictions whereas that of employed workers does not the existence of search externalities makes the retirement age of unemployed workers intrinsically suboptimal considering social security policy issues we show that the complete elimination of the implicit tax on continued activity is not necessarily welfare optimizing in a second best world where the labor market equilibrium suffers from distortions

the effect of shocks to labour market flows on unemployment and participation rates this article presents an analysis of labour market dynamics in particular of flows in the labour market and how they interact and affect the evolution of unemployment rates and participation rates the two main indicators of labour market performance our analysis has two special features first apart from the two labour market states employment and unemployment we consider a third state out of the labour force second we study net rather than gross flows where net refers to the balance of flows between any two labour market states distinguishing a third state is important because the labour market flows to and from that state are quantitatively important focusing on net flows simplifies the complexity of interactions between the flows and allows us to perform a dynamic analysis in a structural vector autoregression framework we find that a shock to the net flow from unemployment to employment drives the unemployment rate and the participation rate in opposite directions while a shock to the
