are the self employed really jacks of all trades testing the assumptions and implications of lazear s theory of entrepreneurship with german data using a large representative german data set and various concepts of self employment this paper tests the jack of all trades view of entrepreneurship by lazear am econ rev 94 2 208 211 2004 consistent with its theoretical assumptions we find that self employed individuals perform more tasks and that their work requires more skills than that of paid employees in contrast to lazear s assumptions however self employed individuals do not just need more basic but also more expert skills than employees our results also provide rather limited support for the idea that human capital investment patterns differ between those who become self employed and those ending up in paid employment

a review of the recent empirical literature on displaced workers this article reviews the empirical literature on job displacement job displacement is widespread and strongly countercyclical tending to peak during economic downturns but concentrated in indus

attitude behavior consistency in tax compliance a cross national comparison abstract are individuals attitudes about paying taxes consistent with their behavior a direct link between attitudes tax morale and behavior tax compliance has long been assumed despite an extensive social scientific literature attesting to the generally weak congruence between the two this study builds on an emerging body of work questioning the link between tax morale and compliance it innovates with a cross national experimental research design whose results indicate that populations with high levels of tax morale exhibit higher evasion rates than those with low levels of tax morale thus the study finds that individual self reported tax morale cannot predict actual evasion choices methodologically the paper contributes the first results of a laboratory experiment on taxation in denmark comparing them to laboratory findings from italy while previous research indicates that these two countries lie at opposite extremes in tax compliance and morale our findings run contrary to culturalist explanations our results show that danes are more likely to evade tax than italians and that individuals attitudes toward tax do not significantly predict their actual evasion choices finally we show that discrepancies in tax behavior between italian and danish subjects are affected by gender and risk aversion

retail pricing and clearance sales sellers of new products are faced with having to guess demand conditions to set price appropriately but sellers are able to adjustprice over time and to learn from past mistakes additionally it is not necessary that all goods be sold with certainty it is sometimes better to set a high price and to risk no sale this process is modeledto explain retail pricing behavior and the time distribution of transactions prices start high and fall as a function of time on theshelf the initial price and rate of decline can be predicted and depends on thinness of the market the proportion of customers who are window shoppers and other observable characteristics copyright 1986 by american economic association

the long term costs of job displacement for young adult workers using nlsy data the authors estimate the long term costs of job displacement for young adults earnings and wage losses were large for the first three years following displacement compared to earnings losses found by other studies for more mature workers however earnings losses for these young adults were short lived with differences between observed and expected earnings narrowing considerably five years after job loss at that point the shortfall in annual earnings relative to what would have been expected absent job loss was 9 for men and 12 5 for women and the shortfall in hourly wages was 21 2 for men young workers also apparently differ from more established workers in the composition of total earnings losses for older workers total losses largely represent actual immediate earnings losses whereas for young workers the loss of opportunities for rapid earnings growth is more important

designing vat systems some efficiency considerations this paper undertakes a cross country analysis of the determinants of vat compliance using data from a sample of 17 oecd countries for 1987 an index of compliance is constructed and regressed against variables which represent characteristics of the countries and their vat rates it is found that a a higher vat rate is associated with lower compliance and this tradeoff limits the revenue maximizing vat rate to under 25 b compliance is substantially lower with multiple vat rates and c an extra dollar spent on administration raises revenue by 12 and longer experience with administering a vat also raises compliance several oecd countries are ranged along a frontier collecting about 8 of gdp through a vat but with rates of 14 to 22 on bases between 60 and 40 of gdp for these the base could only be broadened if the tax rate were lowered copyright 1996 by mit press

the value added tax its causes and consequences almost unknown in 1960 the value added tax vat is now found in more than 130 countries raises around 20 percent of the world s tax revenue and has been the centerpiece of tax reform in many developing countries this paper explores the causes and consequences of the remarkable rise of the vat a key question is whether it has indeed proved as its proponents claim an especially effective form of taxation to address this it is first shown that a tax innovation such as the introduction of a vat reduces the marginal cost of public funds if and only if it also leads an optimizing government to increase the tax ratio this observation leads to the estimation on a panel of 143 countries for 25 years of a system of equations describing both the probability of vat adoption and the revenue impact of the vat the results point to a rich set of determinants of vat adoption this being more likely for example if a country has a program with the imf and the less open it is to international trade in the revenue equation the presence of a vat does indeed have a significant impact but also a complex one with a negative intercept effect counteracted by positive effects that are greater the higher are per capita income and more tentatively openness while the sign of the revenue impact of the vat is thus in general ambiguous most countries that have adopted a vat seem to have gained a more effective tax instrument in doing so though this is less apparent in subsaharan africa and most without it seem likely to gain from its adoption

viewpoint beyond carrots and sticks europeans support health nudges abstract all over the world nations are using health nudges to promote healthier food choices and to reduce the health care costs of obesity and non communicable diseases in some circles the relevant reforms are controversial on the basis of nationally representative online surveys we examine whether europeans favour such nudges the simplest answer is that majorities in six european nations denmark france germany hungary italy and the uk do so we find majority approval for a series of nudges including educational messages in movie theaters calorie and warning labels store placement promoting healthier food sweet free supermarket cashiers and meat free days in cafeterias at the same time we find somewhat lower approval rates in hungary and denmark an implication for policymakers is that citizens are highly likely to support health nudges an implication for further research is the importance of identifying the reasons for cross national differences where they exist

assessing the case for social experiments rs ecent academic debates pit two alternative approaches to policy evaluation against one another the first is the experimental approach based on the random assignment of accepted program applicants to a recipient or treatment group and a non recipient or control group the second is the nonexperimental or econometric approach that uses a variety of microdata sources statistical methods and behavioral models to compare the outcomes of participants in social programs with those of nonparticipants the central question addressed in this paper is whether or not randomized social experiments aid in securing answers to basic questions about the evaluation of social programs there are many distinct and complementary approaches to the study of the impact of public policy including full general equilibrium analysis of policy impacts tinbergen 1956 auerbach and kotlikoff 1987 shoven and whalley 1992 kydland and prescott 1991 and less ambitious partial equilibrium microeconomic structural research programs such as those designed to estimate the impact of taxes on labor supply both approaches offer answers to many interesting counterfactual policy questions but their credibility rests critically on the quality of the empirical input used to generate their answers

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

the fragmentation of the bargaining society wage setting in the nordic countries 1950 to 1992 it is commonly believed that corporatist bargaining institutions have been in general decline in the 1980s and 1990s the leading explanations of the purported universal trend toward greater decentralization of collective bargaining are the impact of technological change changes in the occupational structure and growing international economic integration decentralization should be particularly visible in the nordic countries because collective bargaining was more centralized in these countries in the 1960s and 1970s than in any others in western europe in this article the authors present data on the changes in the centralization of wage bargaining in the four nordic countries since 1950 they document that a significant decentralization of collective bargaining has occurred in sweden as is well known but not in the other three the article concludes with a review of possible explanations of swedish exceptionalism

social programs as positive inducements for tax participation a significant amount of non compliance with the personal income tax is due to individuals who have not filed a tax return and so who are not in the system we use experimental laboratory methods to examine the effect of positive inducements for filing a tax return our design captures the essential features of a voluntary income reporting and tax assessment system human participants earn income they must decide whether to file a tax return and conditional upon filing they must choose how much income to report taxes are paid on reported income only unreported income of filers may be discovered via a random audit and the participant then pays owed taxes plus a fine inducements for filing are introduced as treatments a social safety net e g unemployment replacement income that is conditional upon past filing behavior and a tax credit that is available only to those who file our results suggest that an untargeted tax credit can encourage participation but that targeting the credit to low income earners offers a stronger inducement to file also the provision of a social safety net via unemployment benefits has a positive albeit an indirect impact on participation

cooperation and competition in intergenerational experiments in the field and the laboratory there is economic pressure towards the postponement of the retirement age but employers are still reluctant to employ older workers we investigate the comparative behavior of juniors and seniors in experiments conducted both onsite with the employees of two large firms and in a conventional laboratory environment with students and retirees we show that seniors are no more risk averse than juniors and are typically more cooperative both juniors and working seniors respond strongly to competition the implication is that it may be beneficial to define additional incentives near the end of the career to motivate and retain older workers

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

green taxes in a post paris world are millions of nays inevitable turning the paris agreement s greenhouse gas emissions pledges into domestic policies is the next challenge for governments we address the question of the acceptability of cost effective climate policy in a real voting setting first we analyze voting behavior in a large ballot on energy taxes rejected in switzerland in 2015 by more than 2 million people energy taxes were aimed at completely replacing the current value added tax we examine the determinants of voting and find that distributional and competitiveness concerns reduced the acceptability of energy taxes along with the perception of ineffectiveness most people would have preferred tax revenues to be allocated for environmental purposes second at the same time of the ballot we tested the acceptability of alternative designs of a carbon tax with a choice experiment survey on a representative sample of the swiss population survey respondents are informed about environmental distributional and competitiveness effects of each carbon tax design these impacts are estimated with a computable general equilibrium model this original setting generates a series of novel results providing information on the expected environmental effectiveness of carbon taxes reduces the demand for environmental earmarking making distributional effects salient generates an important demand for progressive designs e g social cushioning or recycling via lump sum transfers the case of lump sum recycling is particularly striking it is sufficient to show its desirable distributional properties to make it one of the most preferred designs which corresponds to a completely novel result in the literature we show that providing detailed information on the functioning of environmental taxes may contribute to close both the gap between acceptability ex ante and ex post and the gap between economists prescriptions and the preferences of the general public

wage dispersion and decentralization of wage bargaining this article studies how decentralization of wage bargaining from sector to firm level influences wage levels and wage dispersion we use detailed panel data covering a period of decentralization in the danish labor market the decentralization process provides variation in the individual worker s wage setting system that facilitates identification of the effects of decentralization we find a wage premium associated with firm level bargaining relative to sector level bargaining and that the return to skills is higher under the more decentralized wage setting systems using quantile regression we also find that wages are more dispersed under firm level bargaining compared to more centralized wage setting systems

no taxation without information deterrence and self enforcement in the value added tax abstract claims that the vat facilitates tax enforcement by generating paper trails on transactions between firms contributed to widespread vat adoption worldwide but there is surprisingly little evidence this paper analyzes the role of third party information for vat enforcement through two randomized experiments among over 400 000 chilean firms announcing additional monitoring has less impact on transactions that are subject to a paper trail indicating the paper trail s preventive deterrence effect this leads to strong enforcement spillovers up the vat chain these findings confirm that when taking evasion into account significant differences emerge between otherwise equivalent forms of taxation jel d83 h25 h26 k34 o17

incentives in organizations n 1975 steven kerr published on the folly of rewarding a while hoping for b the argument was simple you get what you pay for kerr distilled this unifying theme from a disparate set of examples involving politicians soldiers doctors orphanage directors professors and students as well as manufacturing and clerical employees and even human resource managers from these examples kerr pp 77980 concluded that two main causes of distorted incentives are fascination with an objective criterion where individuals seek to establish simple quantifiable standards against which to measure and reward performance and overemphasis on highly visible behaviors when some parts of the task are highly visible while others are not it took agency theory 15 years to express kerr s title not to mention to evaluate or extend his conclusions during this period agency theory was obsessed with the tradeoff between incentives and insurance even though clear eyed observations like kerr s about the design and performance of real incentive contracts suggested that several other issues are at least as important fortunately recent work has brought agency theory not only to kerr s position but beyond in this paper i summarize four new strands in agency theory that help me think about incentives in real organizations as a point of departure i begin with a quick sketch of the classic agency model i then discuss static models of objective performance measurement that sharpen kerr s argument repeated game models of subjective performance assessments incentives for skill development rather than simply for effort and incentive contracts between versus within organizations i con

success in entrepreneurship a complementarity between schooling and wage work experience what makes a successful entrepreneur using danish register data we find strong support for the hypothesis that theoretical skills from schooling and practical skills acquired through wage work are complementary inputs in the human capital earnings function of entrepreneurs in fact we find that schooling only pays off in combination with wage work experience as the returns to schooling are insignificant when the entrepreneur has no wage work experience the results are extremely robust toward more flexible specifications including fixed effect estimations dealing with unobserved heterogeneity furthermore the interaction term is negligible for non entrepreneurs suggesting that the complementarity between wage work experience and schooling is a distinctive characteristic of entrepreneurs

earnings losses of displaced workers revisited recent literature reviews conclude that job displacement results in sustained earnings losses bruce c fallick 1996 lori g kletzer 1998 and that estimates of the size of those reductions vary with the type of data used in the analysis the industry within which displacement occurs and business cycle conditions the largest estimated losses were obtained using administrative data from pennsylvania during the 1970s and 1980s louis s jacobson robert j lalonde and daniel g sullivan 1993a the data covered a period of high unemployment in a heavily indus trialized state characterized by disproportionate job losses in manufacturing thus the ability to generalize those results to more favorable economic times and states with a greater reliance on service sector employment has been questioned to address these issues administrative data are used to similarly examine the impact of job displacement on earnings losses of workers in connecticut from 1993 to 2004 the work of jacobson lalonde and sullivan jls also provided important methodologi cal advancement by adapting analytical techniques developed for program evaluation james j heckman and v joseph hotz 1989 to the context of job displacement the same techniques fixed effects and time trend estimators as those used in the original jls publication are initially employed here then the methods are extended to include matching estimators developed since their publication both nearest neighbor estimators of average treatment on the treated att and differenced average treatment on the treated datt are adapted to the context of this study heckman hidehiko ichimura and petra todd 1997 heckman et al 1998 and rajeev h dehejia and sadek wahba 1999 2002 the results presented here for connecticut differ in some ways from those found in the work of jls using data from pennsylvania in the period immediately following job loss regardless of the technique employed earnings reductions for workers displaced through mass layoff range from 32 percent to 33 percent jls reported immediate losses of more than 40 percent six years later using the same estimators as jls earnings reductions in connecticut range from 13 percent to 15 percent they report sustained losses in pennsylvania of 25 percent the smaller long term impacts in connecticut demonstrate that under more ordinary economic times esti mated losses from administrative data lie within the range observed using other data sources this finding resolves a long standing conflict among the results of high quality studies that have used differing data sources to study earnings reductions following job loss 1 using two different matching estimators earnings losses six years after mass layoff are 12 percent the matching estimators compare those who experienced mass layoff to compari sons with the same ex ante probability of the event these smaller losses are consistent with the

getting the word out enforcement information dissemination and compliance behavior the question for the tax authority is how individuals become aware of enforcement effort to be an effective tool in reducing tax evasion taxpayers must be aware of the current audit and penalty regime we use laboratory experiments to examine the compliance impact of types of information dissemination regarding audit frequency and results the information includes official information disseminated by the tax authority and unofficial or informal communications among taxpayers our results indicate that the effect of the type of post audit information is conditional on whether the taxpayer is well informed of the audit rate prior to filing we find that the tax authority would be served by pre announcing audit rates credibly and by emphasizing the previous period audit frequency in annual reporting of enforcement effort

taxpayer response to an increased probability of audit evidence from a controlled experiment in minnesota abstract in 1995 a group of 1724 randomly selected minnesota taxpayers was informed by letter that the returns they were about to file would be closely examined compared to a control group that did not receive this letter low and middle income taxpayers in the treatment group on average increased tax payments compared to the previous year which we interpret as indicating the presence of noncompliance the effect was much stronger for those with more opportunity to evade in fact the difference in differences is not statistically significant for those who do not have self employment or farm income and do not pay estimated tax surprisingly however the reported tax liability of the high income treatment group fell sharply relative to the control group

efficient tax reporting the effects of taxpayer liability information services the complexity of the individual income tax system can give rise to both under and overreporting of liability thus creating a wedge between taxpayer perceptions of the price of public services and their actual cost and potentially leading to budget misallocations and associated efficiency losses this study uses theory and experiments to evaluate the effectiveness of taxpayer service programs that endeavor to resolve uncertainty over tax liability to do so we induce uncertainty over tax liability and investigate the effects of both service accuracy and reliability we find participants are less likely to file when tax liability is uncertain but the provision of information offsets this effect furthermore it appears that simply providing a service even one that imperfectly reveals liability increases the propensity to file and the accuracy of the filing when a service that promises to resolve uncertainty completely is requested but not delivered the result is underreporting even more severe than in a setting where no service is available jel h2 h26 c91

healthy sustainable and plant based eating perceived mis match and involvement based consumer segments as targets for future policy abstract given the inseparable environmental and health impact of dietary habits integrating health and sustainability goals has become a highly topical issue in policy development and communication to encourage consumers to adopt healthier and more sustainable diets increasing evidence indicates that it is possible to develop diets that are both environmentally sustainable and healthy but their potential success largely depends on consumers willingness and ability to change their behavior this study investigates consumer perceptions of the match or mismatch between healthy and sustainable diets and gives insight into consumers motivation to eat healthily and sustainably as measured by involvement data were collected in spring 2014 through a cross sectional quantitative online survey with samples representative for age gender and region in four european union eu countries united kingdom germany belgium and the netherlands n 2783 the images of a healthy diet a sustainable diet and a plant based diet were found to be highly compatible based on a strongly observed match between european consumers perceptions of these concepts half of the participants were highly involved in healthy eating and one third in both healthy and sustainable eating informational food policy actions targeting both healthy and sustainable food consumption behavior are recommended to address issues relevant to the target segments taking into account their levels of involvement increasing consumers motivation and involvement in health and sustainability emerges as a key trigger for increasing healthy and sustainable eating

a comparison of naive and experienced bidders in common value offer auctions a laboratory analysis laboratory economics experiments typically use financially motivated students as subjects an ongoing issue is whether this is an appropriate subject pool since the students are typically inexperienced in the types of decision making required of them in the lab this paper addresses this issue in the context of common value offer auctions as we compare the behaviour of experienced business executives in the construction contract industry experts with that of naive student subjects results of previous research of this sort have been equivocal in some cases experts make the same errors as novices in other cases they do not hogarth and reder i987 a series of sealed bid common value offer auctions in which bidders compete for the right to supply an item of unknown cost were conducted inherent to common value auctions cvas is an adverse selection problem which may result in below normal or negative profits the winner s curse experimental studies have documented the presence of the winner s curse with financially motivated student subjects in high price demand side auctions kagel et al i986 kagel and levin i986 the experiments reported here generalise these earlier studies from bid to offer auctions also in employing offer auctions we establish a setting with which our experts are familiar thus allowing their experience the best chance to manifest itself

endogenous audits uncertainty and taxpayer assistance services theory and experiments abstract in recent years there has been a sharp rise in the information available to individual income taxpayers such as through tax preparation software provided by third parties and support available by tax agencies but the effects of this information on tax reporting are not well understood within a setting characterized by an endogenous audit process and taxpayer uncertainty this study uses theory and laboratory experiments to investigate the effects of taxpayer assistance services that better inform taxpayers about their tax liability and the audit process the endogenous audit rule we study is simple yet relative to existing work is more likely to characterize the actual incentives facing taxpayers among our findings and in contrast to the case of purely random audits in theory the effect of providing more accurate information on tax liability is ambiguous and we find support empirically for increased tax underreporting even in a setting where theory predicts the opposite this unanticipated result is mitigated when services provide better information on both liability and the audit process suggesting that audit information may be more salient to participants

returns to schooling in self employment abstract this paper challenges the idea that returns to schooling in self employment are similar to those in wage work by establishing a non linear relationship with very low returns for most educational levels in self employment we conclude that previous log linear specifications in the self employment literature have missed significant variation in the true relationship between education and earnings

how destructive is creative destruction effects of job loss on job mobility withdrawal and income we analyze short and long term effects of worker displacement our sample consists of male workers displaced from norwegian manufacturing plants we find that displacement increases the probability of leaving the labor force by 31 the drop out rate from the labor force is particularly high in the first years following displacement the average earnings effects for those who remain in the labor force are moderate a 3 loss relative to non displaced workers after seven years splitting displaced workers on within and between firm movers we find that the estimated earnings loss is entirely driven by between firm movers who experience a 3 6 loss transfers to other plants within multi plant firms upon displacement are quite common our results support the view that human capital is partly firm specific and partly industry specific we find no evidence suggesting that human capital is plant specific

commitment to pay taxes results from field and laboratory experiments abstract a tax authority s ability to successfully collect taxes depends on its relationship with the taxpayers as well as their commitment to contribute to the common good in this paper we examine the effect of promises on tax compliance aimed at fostering taxpayer commitment first in a field experiment we investigate whether tax compliance changes when taxpayers make a formal promise to pay their taxes on time with compliance rewarded by entry into a lottery for either a financial or nonfinancial in kind reward we then complement this analysis with a laboratory experiment in which we measure the effect of promises in the different compliance domain of tax honesty and contrast the effect of a pure promise to pay with schemes that pair the promise with a reward offer we find that taxpayers with a history of compliance or high scores on tax morale are more likely to make the promise but solely offering the possibility to make a promise does not lead to a change in compliance behavior whether or not compliance improves depends on the type of reward to which the promise is linked in our experimental analyses for example compliance only increases if the reward for promise fulfillment is nonfinancial

monetary rewards and decision cost in experimental economics a survey of thirty one experimental studies which report data on the comparative effects of monetary rewards and opportunity cost shows 1 several studies in which increased rewards shift the central tendency of the data toward the predictions of rational models 2 in virtually all cases rewards reduce the variance of the data around the predicted outcome this is consistent with a model in which rewards are balanced against decision cost in agent behavior and explicates the argument that when rational models fail it can be attributed to low opportunity cost of deviations from the rational prediction

tax rates and tax evasion evidence from missing imports in china tax evasion by its very nature is difficult to observe we quantify the effects of tax rates on tax evasion by examining the relationship in china between the tariff schedule and the evasion gap which we define as the difference between hong kong s reported exports to china at the product level and china s reported imports from hong kong our results imply that a one percentage point increase in the tax rate is associated with a 3 percent increase in evasion furthermore the evasion gap is negatively correlated with tax rates on closely related products suggesting that evasion takes place partly through misclassification of imports from higher taxed categories to lower taxed ones in addition to underreporting the value of imports

unwilling or unable to cheat evidence from a tax audit experiment in denmark this paper analyzes a tax enforcement field experiment in denmark in the base year a stratified and representative sample of over 40 000 individual income tax filers was selected for the experiment half of the tax filers were randomly selected to be thoroughly audited while the rest were deliberately not audited the following year threat of audit letters were randomly assigned and sent to tax filers in both groups we present three main empirical findings first using baseline audit data we find that the tax evasion rate is close to zero for income subject to third party reporting but substantial for self reported income since most income is subject to third party reporting the overall evasion rate is modest second using quasi experimental variation created by large kinks in the income tax schedule we find that marginal tax rates have a positive impact on tax evasion for self reported income but that this effect is small in comparison to legal avoidance and behavioral responses third using the randomization of enforcement we find that prior audits and threat of audit letters have significant effects on self reported income but no effect on third party reported income all these empirical results can be explained by extending the standard model of rational tax evasion to allow for the key distinction between self reported and third party reported income

ghost house busters the electoral response to a large anti tax evasion program the incentives of political agents to enforce tax collection are key determinants of the levels of compliance we study the electoral response to the ghost buildings program a nationwide anti tax evasion policy in italy that used innovative monitoring technologies to target buildings hidden from tax authorities two million buildings were registered as a result of the program our difference in differences identification strategy exploits both variation across towns in the ex ante program scope to increase enforcement as well as administrative data on actual building registrations local incumbents experience an increase in their reelection likelihood as a consequence of the policy in addition these political returns are higher in areas with lower tax evasion tolerance and with higher speed of public good provision implying complementarity among enforcement policies the underlying tax culture and government efficiency

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

in the right place at the wrong time the role of firms and luck in young workers careers we examine administrative data on young german workers and their employers to study the long term effects of an early career job loss to account for nonrandom sorting of workers into firms with different turnover rates and for selective job mobility we use changes over time in firm and age specific labor demand as an instrument for displacement we find that wage losses of young job losers are initially 15 percent but drop to zero within five years only workers leaving very large establishments suffer persistent losses a comparison of estimators implies that initial sorting negative selection and voluntary job mobility biases ordinary least squares estimates toward finding permanent negative effects of early displacements

does job loss shorten life this paper examines the impact of job loss on overall and cause specific mortality using linked employer employee data we identified the workers displaced due to all establishment closures in sweden in 1987 and 1988 hence we have extended the case study approach which has dominated the plant closure literature the overall mortality risk among men increased by 44 percent during the first four years following job loss while there was no impact on either female overall mortality or in the longer run for both sexes however there was an about twofold short run increase in suicides and alcohol related mortality

mindless eating and healthy heuristics for the irrational food choice decisions are not the same as intake volume decisions the former determine what we eat soup or salad the latter determine how much we eat half of the bowl or all of it large amounts of money time and intelligence have been invested in understanding the physiological mechanisms that influence food choice james o hill forthcoming much less has been invested in understanding how and why our environment influences food consumption volume yet environmental factors such as package size plate shape lighting variety or the presence of others affect our food consumption volume far more than we realize wansink 2006 whereas people can acknowledge that environmental factors influence others they wrongly believe they are unaffected perhaps they are influenced at a basic level of which they are not aware a better understanding of these drivers of consumption volume will have immediate implications for research policy and personal interventions there are three objectives of this paper 1 explain why environmental factors may unknowingly influence food consumption 2 identify resulting myths that may lead to is specified models or misguided policy recommendations and 3 offer clear direction for future research policy and personal dietary efforts

putting firms into optimal tax theory firms are for the most part absent from the modern theory of optimal taxation their disappearance dates from the foundational models developed by peter a diamond and james a mirrlees 1971 in which firms are simply mechanical vehicles for combining productive inputs into output in cost minimizing proportions in contrast firms play a central role in all modern tax systems mostly for a reason stated by richard m bird 1996 the key to effective taxation is information and the key to information in the modern economy is the corporation in most countries firms remit the majority of tax revenues to the government either with regard to taxes legally owed by businesses or through withholding of taxes legally owed by employees or other businesses even when businesses are not required to remit taxes they are often required to file information reports that can facilitate monitoring of tax liabilities the lack of a theoretical framework that features firms impedes rigorous welfare analysis of a number of important policy issues one such example is the comparative evaluation of a uniform retail sales tax rst versus a value added tax vat in the standard model these two taxes both remitted entirely by businesses are equivalent consumption taxes but most experts consider the vat to be clearly superior on administrative grounds a view echoed in the recent report of the president s advisory panel on federal tax reform 2005 we propose a simple framework in which these and other issues can be analyzed the new framework recognizes that a tax code must be backed up by an administrative and enforcement structure

mechanism experiments and policy evaluations randomized controlled trials are increasingly used to evaluate policies how can we make these experiments as useful as possible for policy purposes we argue greater use should be made of experiments that identify the behavioral mechanisms that are central to clearly specified policy questions what we call mechanism experiments these types of experiments can be of great policy value even if the intervention that is tested or its setting does not correspond exactly to any realistic policy option

the external validity of experimental economics techniques analysis of demand behavior this paper examines the parallelism which exists between demand behavior determined from the sale of a private good in an actual real world field setting and in a laboratory auction setting the demand behavior observed in the two settings is significantly the same leading to the corroboration of the thesis that there is often correspondence between laboratory and real world behavior

the effects of human capital interventions on entrepreneurial performance in industrialized countries this paper provides a systematic review of studies on the effects of human capital interventions on entrepreneurial performance in industrialized countries we identify 21 experimental and quasi experimental studies published before september 2018 these studies examine the effects of business training formal education and entrepreneurship education their performance outcomes include firm profits firm size and entrepreneurial earnings the main finding across these studies is that these interventions do not have statistically significant effects formal education is the only exception showing positive effects on firm profits and entrepreneurial earnings yet these effects are small in magnitude evidence is inconclusive regarding effect duration these findings stand in stark contrast to correlational studies which tend to find large positive correlations between human capital interventions and entrepreneurial performance we therefore conclude that correlational studies tend to overestimate the benefits of human capital interventions moreover our estimates show that the interventions are associated with moderately low additionality

fighting corruption to improve schooling evidence from a newspaper campaign in uganda what are the most effective ways to increase primary school enrollment and student learning we argue that innovations in governance of social services may yield the highest return since social service delivery in developing countries is often plagued by inefficiencies and corruption we illustrate this by using data from an unusual policy experiment a newspaper campaign in uganda aimed at reducing capture of public funds by providing schools parents with information to monitor local officials handling of a large education grant program the campaign was highly successful and the reduction in capture had a positive effect on enrollment and student learning jel d73 i22 o12

on the external validity of laboratory tax compliance experiments i introduction laboratory methods are now widely accepted as a methodological approach in economics and increasingly they have been used to examine specific public policy issues there is much to be gained from careful laboratory experiments they offer a low cost means of testing and replicating policy innovations and they generate precise data on individual behavior thereby allowing estimation of behavioral responses importantly they allow many policy innovations to be introduced singly and exogenously in a controlled environment and as a result laboratory experiments are typically seen as having a high degree of internal validity brewer 2000 campbell and stanley 1966 shadish cook and campbell 2002 because the causal relation between variables can be properly demonstrated however as emphasized by plott 1987 using laboratory experiments can allow more general inferences regarding human behavior only when the setting implemented in the laboratory parallels what is observed in the naturally occurring world even beyond this requirement of parallelism is the need for generalizing behavioral observations from the laboratory to the field or external validity internal validity can be demonstrated through the evaluation of the design however external validity can only be verified empirically and only with respect to the specific setting being investigated this paper investigates the external validity of laboratory experiments and does so in the context of experiments on tax compliance behavior tax evasion is central to many important policy questions current estimates report the tax gap or difference between taxes owed and taxes paid in the united states to be 450 billion annually internal revenue service 2012 beyond these massive revenue losses evasion creates major misallocations in resource use when individuals alter their behavior to cheat on their taxes its presence requires that government expend resources to detect noncompliance to measure its magnitude and to penalize tax evasion evasion alters the distribution of income in arbitrary unpredictable and unfair ways and it may contribute to feelings of unjust treatment and disrespect for the law more broadly it is not possible to understand the true impact of taxation without recognizing the existence and the effects of tax evasion laboratory methods have been used to examine a wide range of policies that may affect the compliance decision policies that have not always proven amenable to either theoretical analyses or empirical analyses with field data however laboratory studies of compliance are sometimes viewed with skepticism the most common criticism is that the student subjects typically used in experiments may not be representative of taxpayers undergraduates may have little experience with filing tax returns and their economic and demographic backgrounds may differ from those of taxpayers another criticism is that the context of laboratory compliance experiments does not closely enough resemble the context in which actual compliance decisions are made as a result there is a concern that experimental results on policy innovations that rely upon student subjects in laboratory compliance experiments cannot be generalized to the population it is this issue that we examine here building on previous research we present several types of evidence on the external validity of experiments on individual compliance decisions a first question examines whether behavior of laboratory participants is replicated by behavior of individuals making a similar decision in the naturally occurring world that is do participants in laboratory experiments exhibit different patterns of behavior than individuals in a similar naturally occurring setting to answer this question we utilize a special data set from the u s internal revenue service irs assembled as part of its national research program nrp

audit state dependent taxpayer compliance theory and evidence from colombia we develop and analyze a dynamic model of individual taxpayer compliance choice that predicts audit state dependent taxpayer compliance by distinguishing between forward looking versus myopic versus naive behavior we then test experimentally the audit state dependent model by reporting the results from the first tax compliance experiment run in colombia we find that subjects compliance rates increase with greater enforcement we also find more novel results fine rates should be increased after an audit and nudging myopic individuals toward reporting a constant rather than a fluctuating proportion of income would benefit both the taxpayer and the tax authority jel h26 c91

searching for ghosts who are the nonfilers and how much tax do they owe this paper is about ghosts individuals who fail to comply with their income tax filing requirements as their name suggests the identities and characteristics of these individuals are shrouded in mystery in this paper we attempt to de mystify the issues surrounding ghosts and examine their role in the compliance process we begin by extending a standard model of tax evasion to account for the existence of ghosts we then examine the empirical significance and policy relevance of our extension using a unique data set containing detailed tax and audit information for both filers and nonfilers of u s federal income tax returns 2001 elsevier science b v all rights reserved

do students behave like real taxpayers in the lab evidence from a real effort tax compliance experiment we report on data from a real effort tax compliance experiment using three subject pools students who do not pay income tax company employees whose income is reported by their employer and self employed taxpayers who are responsible for filing and payment while compliance behavior is unaffected by changes in the level of or information about the audit probability higher fines increase compliance we find subject pool differences self assessed taxpayers are the most compliant while students are the least compliant through a simple framing manipulation we show that such differences are driven by norms of compliance from outside the lab

experimental methods for the general economist five lessons from the lab i review five primary results from experimental economics that impact the economics profession as a whole these results regard the relative un importance of subject sophistication in laboratory markets the importance of gender on economic outcomes the propensity for humans to behave in less than fully rational ways the importance of trading institutions on economic performance and the behavioral relevance of economic theory i find that economics as a profession has benefited from the use of experimental methods by fostering a dialogue between theorists and empiricists better informing policy and improving data collection techniques

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

the income losses of displaced workers abstract we use a new matched worker firm dataset for the united kingdom to estimate the income loss resulting from firm closure and mass layoffs we track workers for up to nine years after the displacement event and the availability of predisplacement characteristics allows us to implement difference in differences estimators using propensity score matching methods income losses during the first five years after the displacement event are in the range 18 35 percent per year for workers whose firm closes down and 14 25 percent for workers who exit a firm which suffers a mass layoff these losses are largely due to periods of nonemployment which is consistent with previous work from europe but contrasts with that from the united states

examining the formation of human capital in entrepreneurship a meta analysis of entrepreneurship education outcomes abstract effective human capital formation through the medium of entrepreneurship education and training eet is of increasing concern for governments as eet is growing rapidly across the world unfortunately there is a lack of consistent evidence showing that eet helps to create more or better entrepreneurs we undertake the first quantitative review of the literature and in the context of human capital theory find that there is indeed support for the value of eet based on 42 independent samples n 16 657 we find a significant relationship between eet and entrepreneurship related human capital assets r w 217 and entrepreneurship outcomes r w 159 the relationship between eet and entrepreneurship outcomes is stronger for academic focused eet interventions r w 238 than for training focused eet interventions r w 151 we find evidence of heterogeneity in many of our correlations and recommend that future studies examine potential moderators to more clearly delineate eet effect sizes we also find a number of methodological weaknesses among the studies analyzed and that those studies with lower methodological rigor are overstating the effect of eet recommendations to improve the quality of future work in the field are provided

the use of field experiments to increase tax compliance governments have become increasingly interested in the explosion of research into taxpayer behaviour this article briefly reviews two main theories of tax compliance deterrence and non deterrence before discussing the recent rapid rise of natural field experiments nfes in this area these nfes represent a win win for policy makers and academics since they can test theories while also evaluating the impact of a specific intervention in the real world the evidence from nfes shows that deterrence approaches improve compliance while the case for non deterrence approaches is less conclusive at the moment nfes could be improved by paying more attention to findings from behavioural science that apparently incidental factors such as timing framing and complexity substantially affect whether compliance occurs or not new directions for future studies include network effects tax payments in addition to declarations the behaviour of firms the provision of public goods and the relationship between attitudes and behaviour

employment and retirement following a late career job loss the frequency of job loss among workers in late career has risen disproportionately in recent years the effects of job loss on these workers are potentially severe their earnings capacity savings and retirement expectations are likely to be dramatically affected and they may take substantially longer to be re employed however despite these reasons for heightened concern relatively little is known about the economic consequences of late career job loss among recent cohorts of workers this paper presents findings from an ongoing research project using the health and retirement study that focuses on the economic impacts of late career job loss on employment and retirement patterns as well as on earnings and assets this abstract was borrowed from another version of this item

are workers permanently scarred by job displacements this paper investigates whether workers suffer lasting scars following job displacements using david t ellwood s 1982 terminology scars represent persistent effects whereas blemishes are transitory adjustments which dissipate over time more precisely dislocated individuals are defined as scarred if they continue to earn less or to be unemployed more than their nondisplaced counterparts even after the conclusion of a several year adjustment period
