physical appearance and wages do blondes have more fun abstract this study contributes to the economics literature that links physical characteristics to labour market outcomes by investigating the influence of hair colour on women s own wages and also their spouse s wages using u s panel data we find that blonde women receive large wage premiums

beauty premium and marriage premium in search equilibrium theory and empirical test we propose a theoretical explanation for the so called beauty premium our approach relies entirely on search frictions and the fact that physical appearance plays an important role in attracting a marriage partner we analyze the interaction between frictional labor and marriage markets making use of what we label constrained job search the optimal strategy entails different reservation wages for different men and we establish the existence of a search equilibrium characterized by a beauty premium and or marriage premium predicted profiles of premia allow for potential falsification tests and point to relevant empirical evidence in support of our theory

the economic value of teeth abstract this paper examines the effect of oral health on labor market outcomes by exploiting variation in fluoridated water exposure during childhood the politics surrounding the adoption of water fluoridation by local governments suggests exposure to fluoride is exogenous to other factors affecting earnings exposure to fluoridated water increases women s earnings by approximately 4 percent but has no detectable effect for men furthermore the effect is largely concentrated amongst women from families of low socioeconomic status we find little evidence to support occupational sorting statistical discrimination and productivity as potential channels with some evidence supporting consumer and possibly employer discrimination

individual risk attitudes measurement determinants and behavioral consequences this paper studies risk attitudes using a large representative survey and a complementary experiment conducted with a representative subject pool in subjects homes using a question asking people about their willingness to take risks in general we find that gender age height and parental background have an economically significant impact on willingness to take risks the experiment confirms the behavioral validity of this measure using paid lottery choices turning to other questions about risk attitudes in specific contexts we find similar results on the determinants of risk attitudes and also shed light on the deeper question of stability of risk attitudes across contexts we conduct a horse race of the ability of different measures to explain risky behaviors such as holdings stocks occupational choice and smoking the question about risk taking in general generates the best all round predictor of risky behavior

after the paris agreement measuring the global decarbonization wedges from national energy scenarios the new bottom up approach of the paris agreement calls for a better understanding of the domestic dimension of development pathways and of the implications for global emissions trajectory to this end it is of strategic importance to provide a common framework that makes it possible to identify the key decarbonization wedges at the national level and to highlight the potential benefits of international cooperation the article proposes an advanced index decomposition analysis methodology based on sectoral energy service indicators and on a specific decomposition in the power sector for quantifying the contribution of different mitigation strategies it is applied to national deep decarbonization pathways elaborated in the deep decarbonization pathway project ddpp by the sixteen largest ghg emitting countries in a global perspective the results reveal the key role of energy efficiency and decarbonization of energy carriers in the industry sector deployment of renewables in the power sector and to a lesser extent coal gas substitution and efficiency and energy decarbonization in the transport sector the analysis also calls for a deeper understanding of the role a reduction in energy service demand can play in mitigation scenarios and of the respective contribution for industry of energy efficiency and structural change

beauty and the labor market the authors examine the impact of looks on earnings using interviewers ratings of respondents physical appearance plain people earn less than average looking people who earn less than the good looking the plainness penalty is 5 to 10 percent slightly larger than the beauty premium effects for men are at least as great as for women unattractive women have lower labor force participation rates and marry men with less human capital better looking people sort into occupations where beauty may be more productive but the impact of individuals looks is mostly independent of occupation suggesting the existence of pure employer discrimination copyright 1994 by american economic association

skills in the city this paper documents the allocation of skills across cities and estimates the impact of agglomeration on the hedonic prices of worker skills we find that large cities are more skilled than are small cities but only to a modest degree we also show that the increase in productivity associated with agglomeration as measured by the urban wage premium is larger for workers with stronger cognitive and people skills in contrast motor skills and physical strength are not rewarded to a greater degree in large cities urbanization thus enhances thinking and social interaction rather than physical abilities these results are robust to a variety of estimation strategies including using nlsy variables that control for worker quality and a worker msa fixed effect specification

separation of powers and political accountability political constitutions are incomplete contracts and therefore leave room for abuse of power in democracies elections are the primary mechanism for disciplining public officials but they are not sufficient separation of powers between executive and legislative bodies also helps to prevent the abuse of power but only with appropriate checks and balances checks and balances work by creating a conflict of interest between the executive and the legislature yet requiring both bodies to agree on public policy in this way the two bodies discipline each other to the voters advantage under appropriate checks and balances separation of powers also helps the voters elicit information

the effect of democracy and press freedom on corruption an empirical test this paper tests the effect of democracy and press freedom on corruption the empirical investigation carried out in this paper suggests that democracy and press freedom can have significant impact on corruption

long run labour market and health effects of individual sports activities abstract this microeconometric study analyzes the effects of individual leisure sports participation on long term labour market variables health and subjective well being indicators for west germany based on individual data from the german socio economic panel study gsoep 1984 2006 econometric problems due to individuals choosing their own level of sports activities are tackled by combining informative data and flexible semiparametric estimation methods with a specific way to use the panel dimension of the data the paper shows that sports activities have sizeable positive long term labour market effects in terms of earnings and wages as well as positive effects on health and subjective well being

causes and effects of corruption what has past decade s empirical research taught us a survey corruption has fierce impacts on economic and societal development and is subject to a vast range of institutional jurisdictional societal and economic conditions it is this paper s aim to provide a reassessment and a comprehensive state of the art survey of existing literature on corruption and its causes and effects a particularly strong focus is put on presenting and discussing insights resulting from empirical research and contrasting recent with older findings

participation in school sponsored sports and academic spillovers new evidence from the early childhood longitudinal survey the link between participation in school sponsored sports and academic performance has been studied extensively in the literature whilst previous studies tend to show positive academic spillovers

stature and the standard of living research on the standard of living now emphasizes alternatives or supplements to the national income accounts this paper reviews the results of two decades of research using stature as a measure of health aspects of human welfare after comparing and contrasting stature with per capita income i consider height patterns discovered by economic historians that challenge traditional beliefs about the past including long term trends cycles in heights and the dreadfully small stature of slave children that was followed by catch up growth the paper concludes with comparisons to work in development economics and suggestions for research

effectiveness of electoral systems for reducing government corruption a game theoretic analysis abstract a theoretical model is developed for predicting the relative effectiveness of different electoral systems for reducing government corruption we consider voting games in which parties with known corruption levels and known positions on a major policy question compete for legislative seats we find that approval voting and proportional representation are fully effective in the sense that all equilibria exclude corrupt parties from legislative seats plurality voting is partly effective in the sense that there always exist some equilibria that exclude corrupt parties borda voting is ineffective because for some political situations no equilibria can guarantee the exclusion of corrupt parties journal of economic literature classification number d72

high powered performance pay and crowding out of nonmonetary motives a previous literature cautions that paying workers for performance might crowd out nonmonetary motives to work hard empirical evidence from the field however has been based on between subjects designs that are best suited for detecting crowding out due to low powered incentives high powered incentives in the workplace tend to increase output but it is unknown whether this masks crowding out this paper uses a within subject experimental design and finds evidence that crowding out also extends to high powered incentives in a real work setting with paid workers there is individual heterogeneity however with a minority of workers reporting crowding in of motivation thus the impact of performance pay might depend on the mix of worker types data and the online appendix are available at https doi org 10 1287 mnsc 2017 2846 this paper was accepted by uri gneezy behavioral economics

does globalization affect growth evidence from a new index of globalization the study develops an index of globalization covering its three main dimensions economic integration social integration and political integration using panel data for 123 countries in 1970 2000 it is analysed empirically whether the overall index of globalization as well as sub indexes constructed to measure the single dimensions affect economic growth as the results show globalization indeed promotes growth the dimensions most robustly related with growth refer to actual economic flows and restrictions in developed countries although less robustly information flows also promote growth whereas political integration has no effect

the hotspots reference routes and research trends of marginal abatement costs a systematic review abstract as one of the most effective means of evaluating environmental policies marginal abatement costs macs have been adopted in a growing body of research this study characterizes the mac related literature from 1993 to 2018 on web of science based on a systematic review bibliometric analysis and mind mapping the results classify the research hotspots into influential factors methods and empirical applications the three most frequently mentioned influential factors are technical change discount rates and energy prices compared with top down models bottom up models including engineering model and expert based method are the most widely used improvements in the former focus on strengthening market behavior effect while those in the latter aim to overcome the weaknesses of negative costs and lack of interaction across measures mac applications focus on environmental policies with two new research areas recently emerging co benefits and sectoral abatement costs furthermore a reference route is proposed by summarizing the applicability of methods and matching relationships among influential factors methods and empirical problems finally potential research directions are summarized based on the identified research hotspots and a similar co word analysis in marginal cost field such as considering the effects of both multiple influential factors and the interaction among factors on maccs

intergenerational transmission of risk attitudes a revealed preference approach using data the german socio economic panel gsoep we investigate whether the willingness to take risks which is revealed via observed choices of occupation is transmitted from parents to children our approach resembles the one by dohmen et al 2008 who investigate the same question using stated preferences as risk variable we use earnings risk measured by the cross sectional coecient of residual variation obtained from mincerian wage regressions we nd that fathers riskiness of the job chosen is a signicant determinant of sons occupational risk our results are robust to dierent specications underpinning the hypothesis of intergenerational transmission of risk preferences

short criminals stature and crime in early america abstractwe consider the extent to which an individual s height affected the age at which he entered into criminal activity in early america using data on prisoners incarcerated in pennsylvania s nineteenth century prisons we show that prisoners were short relative to the contemporary population then using weibull continuous time duration econometric models we show that age at entry into criminal activity was negatively associated with an individual s height after controlling for several individual characteristics the results are consistent with recent research showing that shorter individuals face less attractive legitimate labor market opportunities because lower stature is associated with lower cognitive ability and because of general discrimination against shorter people

the synthesis of bottom up and top down approaches to climate policy modeling electric power technology detail in a social accounting framework abstract hybrid climate policy simulations have sought to bridge the gap between bottom up engineering and top down macroeconomic models by integrating the former s energy technology detail into the latter s macroeconomic framework construction of hybrid models is complicated by the need to numerically calibrate them to multiple incommensurate sources of economic and engineering data i develop a solution to this problem following howitt s howitt r e 1995 positive mathematical programming american journal of agricultural economics 77 329 342 positive mathematical programming approach using data for the u s i illustrate how the inputs to the electricity sector in a social accounting matrix may be allocated among discrete types of generation so as to be consistent with both technologies input shares from engineering cost estimates and the zero profit and market clearance conditions of the sector s macroeconomic production structure

disease and development the effect of life expectancy on economic growth we exploit the major international health improvements from the 1940s to estimate the effect of life expectancy on economic performance we construct predicted mortality using preintervention mortality rates from various diseases and dates of global interventions predicted mortality has a large impact on changes in life expectancy starting in 1940 but no effect before 1940 using predicted mortality as an instrument we find that a 1 percent increase in life expectancy leads to a 1 7 2 percent increase in population life expectancy has a much smaller effect on total gdp however consequently there is no evidence that the large increase in life expectancy raised income per capita

labor market consequences of poor attitude and low self esteem in youth in a recent national survey that asked employers to rank the importance of particular applicant traits for nonsupervisory and production positions applicant s attitude was the only trait that was reported to be very important in fact academic performance years of schooling completed teachers recommendations and industry based credentials certifying applicant skills all ranked lower bowles et al 2000 a second independent survey of employers in holzer and wissoker 2000 also suggests that more weight is placed on a good attitude than on basic skills among new hires of low skilled workers in this article i assess the role of pre labor market attitude and self esteem in explaining disparities observed in the labor market experiences of a sample of high school graduates the apparent importance employers ascribe to attitude and self esteem gives clear reason to expect that such a relationship exists i demonstrate that such survey responses are corroborated by real economic consequences for those with poor attitude and self esteem using longitudinal data on a 1972 cohort of high school graduates i show that high school students who reveal negative attitudes and self esteem subsequently attain fewer years of postsecondary education relative to their high school cohort are less likely to be employed 14 years following high school and where working for pay earn less accounting directly for the labor force participation decision i also document a higher incidence of unemployment among these individuals furthermore i find evidence that negative attitudes and self esteem are associated with jobs later in life that require the individual to spend time working with things as opposed to people for example and that those who exhibit poor pre labor market attitude and self esteem are subsequently more closely supervised at work and given less discretion in their daily activities all told attitude and self esteem in youth are shown to have important and long lasting economic implications in the following section i briefly discuss related literatures specifically two areas of the literature are considered the effect of joblessness on self esteem and the relationship between other noncognitive skills or worker attributes and labor market outcomes section ii then introduces the data and methods used in investigating the relationships in question empirical results are reported in section iii and are followed by some discussion and concluding remarks i previous literature this article is closely related to two areas of existing literature first there exists a small body of literature that documents a relationship between labor market activity and self esteem however this literature has heretofore focused more on the damage of joblessness to an individual s perception of self worth than on the direction of causality considered here for example goldsmith et al 1995 1996a find relationships between contemporaneous joblessness and self esteem and historic joblessness and subsequent self esteem respectively arguably the causality between attitudes and jobless spells is not clearly in one direction or the other in this article i contribute clear evidence of the reverse causation causation running from attitude and self esteem to future labor market outcomes second there is a growing body of literature on the importance of noncognitive skills in wage determination this literature suggests that measures of aggression and withdrawal osborne 1999 individual motivation goldsmith et al 2000 behavioral problems in high school cawley et al 2001 one s locus of control or outlook on life goldsmith et al 1997b osborne 1999 bertrand and mullainathan 2001 coleman and deleire 2003 and mental health bartel and taubman 1979 1986 frank and gertler 1991 mullahy and sindelar 1993 each have predictive power with respect to wages that employer surveys suggest that attitude is highly valued alone leads one to anticipate that attitude be related to earnings

representing induced technological change in models for climate policy analysis induced technological change itc whereby the relative price effects of reducing greenhouse gas emissions stimulate innovation that mitigates the cost of abatement is both tantalizing to decision makers and challenging to represent in the computational economic and engineering models used to analyze climate change policy this overview reconciles the divergent views of technology and technological change within different types of models elucidates the theoretical underpinnings of itc introduces the reader to the techniques of their practical implementation and evaluates the implications for models results

the lmdi approach to decomposition analysis a practical guide in a recent study ang energy policy 32 2004 compared various index decomposition analysis methods and concluded that the logarithmic mean divisia index method is the preferred method since the literature on the method tends to be either too technical or specific for most potential users this paper provides a practical guide that includes the general formulation process summary tables for easy reference and examples

beauty vs brains early labor market outcomes of high school graduates this paper examines the wage returns to attractiveness for young high school graduates findings show that wage returns to attractiveness are large relative to ability and beauty and ability are complements at high attractiveness ratings but substitutes at low ratings

stature skills and adult life outcomes evidence from indonesia abstractwe investigate the effect of height on earnings occupational choices and a subjective measure of wellbeing among indonesian men we explore the extent to which height captures the effects of endowments set before entry in the labour market physical and cognitive skills co determined with stature early in life do not explain much of the height earnings premium directly yet human capital more broadly including cognition educational attainment and other factors related to childhood conditions explains around half of the height premium and does so through occupational sorting indeed taller workers tend to have more education and educated workers tend to work in more lucrative occupations that require brain and social skills not brawn the unexplained share of the height earnings premium may reflect a specific role of stature on social interaction labour market advantages or self assurance we also find a height premium in happiness half of which simply accounts for the educational and e

applicant screening and performance related outcomes a fundamental problem faced by employers is how to elicit effort from employees most economic models suggest that employers meet this challenge by monitoring employees carefully to prevent shirking but there is another option that relies on heterogeneity across employees and that is to screen job candidates to find workers with a stronger work ethic who require less monitoring we might therefore expect employers who screen candidates more intensively to monitor them less using data from a national sample of us employers we find that employers who screen applicants more intensively for factors that should predict work ethic also monitor employees less and also make greater use of systems such as teamwork where monitoring by supervisors is more difficult this screening is also associated with higher wages higher employee productivity and lower involuntary turnover rates screening for other attributes such as work experiences and academic performance does not produce these results jel codes m51 m54 j30

a note on the height wage differential in the uk cross sectional evidence from the bhps abstract using bhps data for the first time evidence for the height earnings relationship is updated for the uk in contrast to prior findings baseline height differentials mainly vanish once individuals occupation and non linear height gradients are accounted for

comparative politics and public finance we propose a model with micropolitical foundations to contrast different political regimes compared to a parliamentary regime the institutions of a presidential congressional regime produce fewer incentives for legislative cohesion but more separation of powers these differences are reflected in the size and composition of government spending a parliamentary regime has redistribution toward a majority less underprovision of public goods and more rents to politicians a presidential congressional regime has redistribution toward powerful minorities more underprovision of public goods but less rents to politicians the size of government is smaller under a presidential regime this last prediction is consistent with cross country data

the intergenerational transmission of income volatility is riskiness inherited this article examines the intergenerational transmission of income risk do risky parents have risky kids income volatility a proxy for income risk is not observed directly instead it must be estimated with substantial error from the time series variability of income i characterize an income process with individual specific volatility parameters and estimate the joint distribution of volatility parameters for fathers and for their adult sons in data from the panel study of income dynamics fathers with higher income volatility have sons with higher income volatility this finding is correlated with but far from fully explained by the intergenerational transmission of risk tolerance and of the propensity for self employment

numeracy and the impact of high food prices in industrializing britain 1780 1850 abstract using census based data on the ability to recall one s age we show that low levels of nutrition impaired numeracy in industrializing england 1780 to 1850 cognitive ability declined among those born during the napoleonic wars the effect was stronger in areas where grain was expensive and relief for the poor an early form of welfare support was limited nutritional shortages had a nonlinear effect on numeracy with severe shortages impairing numeracy more nutrition during childhood also mattered for labor market outcomes individuals born in periods or counties with low numeracy typically worked in occupations with lower earnings

myth or fact the beauty premium across the wage distribution in germany abstract we allow for differential effects of physical appearance across the wage distribution using a technique traditionally used in the finance literature we find an average beauty premium of 2 4 for women which is concentrated at the bottom of the wage distribution the average beauty premium for men is larger at 5 7 and is present throughout the wage distribution both of these vary by education level we find that differences in characteristics such as age family composition labor market attributes etc between beautiful and plain people contribute to the beauty premium identified using traditional regression models isolating this characteristic effect from the unexplained effect using decomposition techniques leads to smaller beauty premia

why beauty matters we decompose the beauty premium in an experimental labor market where employers determine wages of workers who perform a maze solving task this task requires a true skill which we show to be unaffected by physical attractiveness we find a sizable beauty premium and can identify three transmission channels a physically attractive workers are more confident and higher confidence increases wages b for a given level of confidence physically attractive workers are wrongly considered more able by employers c controlling for worker confidence physically attractive workers have oral skills such as communication and social skills that raise their wages when they interact with employers our methodology can be adopted to study the sources of discriminatory pay differentials in other settings

decentralization and corruption evidence across countries the relationship between decentralization of government activities and the extent of rent extraction by private parties is an important element in the recent debate on institutional design the theoretical literature makes ambiguous predictions about this relationship and it has remained virtually unexamined by empiricists the authors make a first attempt at examining the issue empirically by looking at the cross country relationship between fiscal decentralization and corruption as measured by a number of different indices their estimates suggest that fiscal decentralization in government spending is significantly associated with lower corruption moreover they find that the origin of a country s legal system for example civil versus common legal code performs extremely well as an instrument for decentralization the estimated relationship between decentralization when so instrumented and corruption is even stronger the evidence suggests a number of interesting areas for future work including investigating whether there are specific services for which decentralized provision has a particularly strong impact on political rent extraction and understanding the channels through which decentralization succeeds in keeping corruption in check

the synthesis of bottom up and top down approaches to climate policy modeling electric power technologies and the cost of limiting us co2 emissions abstract in the us the bulk of co 2 abatement induced by carbon taxes comes from electric power this paper incorporates technology detail into the electricity sector of a computable general equilibrium model of the us economy to characterize electric power s technological margins of adjustment to carbon taxes and to elucidate their general equilibrium effects compared to the top down production function representation of the electricity sector the technology rich hybrid specification produces less abatement at a higher welfare cost suggesting that bottom up models do not necessarily generate lower costs of abatement than top down models this result is shown to be sensitive to the elasticity with which technologies generating capacities adjust to relative prices

height skills and labor market outcomes in mexico abstract taller workers are paid higher wages a prominent explanation for this pattern is that physical growth and cognitive development share childhood inputs inducing a correlation between adult height and two productive skills strength and intelligence this paper explores the relative roles of strength and intelligence in explaining the labor market height premium among mexican men while cognitive test scores account for a limited share of the height premium roughly half of the premium can be attributed to the educational and occupational choices of taller workers taller workers obtain more education and sort into occupations with greater intelligence requirements and lower strength requirements suggesting a possible role for cognitive skill

comparing model results to national climate policy goals results from the asia modeling exercise abstract while the world has yet to adopt a single unified policy to limit climate change many countries and regions have adopted energy and climate policies that have implications for global emissions in this paper we discuss a few key policies and how they are included in a set of 23 energy and integrated assessment models that participated in the asia modeling exercise we also compare results from these models for a small set of stylized scenarios to the pledges made as part of the copenhagen accord and the goals stated by the major economies forum we find that the targets outlined by the united states the european union japan and korea require significant policy action in most of the models analyzed for most of the models in the study however the goals outlined by india are met without any climate policy the stringency of climate policy required to meet china s copenhagen pledges varies across models and accounting methodologies

strengthening state capabilities the role of financial incentives in the call to public service we study a recent recruitment drive for public sector positions in mexico different salaries were announced randomly across recruitment sites and job offers were subsequently randomized screening relied on exams designed to measure applicants intellectual ability personality and motivation this allows the first experimental estimates of i the role of financial incentives in attracting a larger and more qualified pool of applicants ii the elasticity of the labor supply facing the employer and iii the role of job attributes distance attractiveness of the municipal environment in helping fill vacancies as well as the role of wages in helping fill positions in less attractive municipalities a theoretical model guides each stage of the empirical inquiry we find that higher wages attract more able applicants as measured by their iq personality and proclivity towards public sector work i e we find no evidence of adverse selection effects on motivation higher wage offers also increased acceptance rates implying a labor supply elasticity of around 2 and some degree of monopsony power distance and worse municipal characteristics strongly decrease acceptance rates but higher wages help bridge the recruitment gap in worse municipalities

economic reforms and gender inequality in urban china abstractthis study jointly examines the gender earnings gap and employment rate in urban china using a longitudinal data set that covers the period of 1989 2004 consistent with previous studies we find that gender earnings gap increased by 5 percentage points between 1989 and 1997 since then its changes have become much more moderate actually after controlling for observed characteristics the size of the earnings gap in 2004 is almost the same as it was in 1997 the widening earnings gap in the 1989 1997 period was accompanied by a rising employment gap between men and women particularly among those aged 45 and older the stability in the gender earnings gap in the later years co occurred with a decline in the employment of less educated women

the effect of adolescent experience on labor market outcomes the case of height taller workers receive a wage premium net of differences in family background the disparity is similar in magnitude to the race and gender gaps we exploit variation in an individual s height over time to explore how height affects wages controlling for teen height essentially eliminates the effect of adult height on wages for white men the teen height premium is not explained by differences in resources or endowments the teen height premium is partially mediated through participation in high school sports and clubs we estimate the monetary benefits of a medical treatment for children that increases height

can school sports reduce racial gaps in truancy and achievement while existing research supports that participation in high school athletics is associated with better education and labor market outcomes the mechanisms through which these benefits accrue are not well established using individual microdata collected daily and team specific schedules we retrieve estimates of the causal effect of high school athletic participation on absenteeism suggesting that participation decreases absences driven primarily by reductions in unexcused absences in boys there are also strong game day effects in truancy in both boys and girls with truancy declines on game days more than offset by subsequent absenteeism important heterogeneity by race gender and family structure may serve to substantially reduce racial gaps in truancy and achievement jel i21 l83

beauty job tasks and wages a new conclusion about employer taste based discrimination using novel data from the berea panel study we show that the beauty wage premium for college graduates exists only in jobs where attractiveness is plausibly a productive characteristic a large pr

decomposing the impact of alternative technology sets on future carbon emissions growth abstract what are the drivers of future global carbon dioxide co 2 emissions growth and how would the availability of key energy supply technologies change their relative importance in this paper we apply a novel index number decomposition technique to the results of a multi region multi sector computable general equilibrium model to quantify the influence of five factors on the growth of future carbon emissions 1 growth in global economic activity 2 shifts in the regional composition of gross world product 3 shifts in the sectoral composition of regions gdp 4 changes in sectors energy output ratios and 5 changes in the co 2 intensity of energy sources we elucidate how the relative importance of these factors changes in response to the imposition of a global carbon tax and alternative assumptions about the future availability of key energy supply technologies rising global economic activity and shifts in regional composition put upward pressure on emissions while changes in energy and emission intensity and the sectoral output mix have attenuating effects a global emission tax that increases over time slows economic expansion and shifts the fuel mix with the most pronounced impacts on china india and russia limited availability of carbon capture and storage nuclear and hydroelectric generation all lead to upward shifts in the long run marginal abatement cost curve causing some countries to choose to pay the tax rather than abate

statistical discrimination productivity and the height of immigrants building on the economic research that demonstrates a positive relationship between height and worker ability the author compares wage returns to height for immigrants and for natives to explore possible explanations for the positive wage height gradient using multiple data sets the article presents a robust empirical finding that the wage gains associated with height are almost twice as large for immigrants as for native born individuals this wage relationship occurs because the productivity gap between tall and short immigrants is greater than the productivity gap between tall and short native born workers the author next tests for the possibility that in the relative absence of other sources of information about immigrants employers place more importance on height for immigrants than for native born individuals the evidence does not support the hypothesis of statistical discrimination based on height

height and earnings the role of cognitive and noncognitive skills we use large scale register data on 450 000 swedish males who underwent mandatory military enlistment at age 18 and a subsample of 150 000 siblings to examine why tall people earn more we show the importance of both cognitive and noncognitive skills as well as family background and muscular strength for the height earnings relationship in addition we show that a substantial height premium remains after these factors have been accounted for which originates from very short people having low earnings this is mostly explained by the sorting of short people into low paid occupations which may indicate discrimination by stature

a free press is bad news for corruption abstract this paper tests the proposition that a free press may be a powerful control on corruption we find evidence of a significant relationship between more press freedom and less corruption in a large cross section of countries this result is robust to specification and sample and the relationship is not sensitive to the choice of a particular measure of corruption or of press freedom furthermore we present evidence which suggests that the direction of causation runs from higher press freedom to lower corruption

war and stature growing up during the nigerian civil war the nigerian civil war of 1967 70 was precipitated by secession of the igbo dominated south eastern region to create the state of biafra it was the first civil war in africa the predecessor of many we investigate the legacies of this war four decades later using variation across ethnicity and cohort we identify significant long run impacts on human health capital individuals exposed to the war at all ages between birth and adolescence exhibit reduced adult stature and these impacts are largest in adolescence adult stature is portentous of reduced life expectancy and lower earnings

governance infrastructure and us foreign direct investment this paper examines the statistical importance of governance infrastructure as a determinant of us foreign direct investment fdi in broad terms governance infrastructure represents attributes of legislation regulation and legal systems that condition freedom of transacting security of property rights and transparency of government and legal processes our econometric analysis uses a two stage estimation procedure in the first stage the probability that a country is an fdi recipient is estimated the results indicate that countries that fail to achieve a minimum threshold of effective governance are unlikely to receive any us fdi countries that receive no us fdi are typically countries that do not promote free and transparent markets that have ineffective governments and that often have legal systems that are not rooted in english common law in the second stage the analysis is restricted to those countries that did receive fdi flows the estimated equations focus on the determinants of the amount of fdi received given that a country is a recipient of us fdi governance infrastructure including the nature of the legal system is an important determinant of the amount received

international integration and national corruption we argue that greater degrees of international integration lead to lower levels of corruption which we define as the misuse of public office for private gain we theorize that international factors affect a country s level of corruption through two principal channels one acts through economic incentives altering for various actors the costs and benefits of engaging in corrupt acts the second mode is norma tive prevailing norms in international society delegitimate and stigmatize corrup tion countries that are more integrated into international society are more exposed to economic and normative pressures against corruption we therefore test the fol lowing hypothesis the more a country is tied into international networks of ex change communication and organization the lower its level of corruption is likely to be the analysis of data from approximately 150 countries strongly confirms our expectation

when does weight matter most past empirical work establishes a wage penalty from being overweight in this paper i exploit variation in an individual s weight over time to determine the age when weight has the largest impact on labor market outcomes for white men controlling for weight at younger ages does not eliminate the effect of older adult weight on wage being overweight as a young adult only adds an additional penalty to adult wages however for white women what they weigh in their early twenties solely determines the existence of an adult wage penalty the female early twenties weight penalty has a persistent effect on wages and differences in marital characteristics occupation status or education cannot explain it it also is not a proxy for intergenerational unobservables

gender bias and credit access we extract an exogenous measure of gender bias from survey responses by descendants of u s immigrants on questions about the role of women in society we then use data on around 6 000 small business firms from 17 countries and find that in high gender bias countries female entrepreneurs are more likely to opt out of the loan application process and to resort to informal finance even though banks do not appear to actively discriminate against them these results are not driven by credit risk differences between female and male owned firms or by any idiosyncrasies in the set of countries in our sample

swimming upstream trends in the gender wage differential in the 1980s using michigan panel study of income dynamics data for 1979 and 1988 we analyze how a falling gender wage gap occurred despite changes in wage structure unfavorable to low wage workers the decrease is traced to gender specific factors which more than counterbalanced changes in measured and unmeasured prices working against women supply shifts net of demand were unfavorable for women generally and hurt high skilled more than middle and low skilled women by analyzing wages we find support for the notion of a gender twist in supply and demand having its largest negative effect on high skilled women

the impact of socio political integration and press freedom on corruption abstract the analyses in this study demonstrate a more nuanced understanding of a previously understood phenomenon that openness has a negative relationship with corruption it is argued that this relationship is substantially influenced by the domestic context a relationship that has been underdeveloped by previous empirical studies focusing on social and political integration i find that the effect of openness on corruption is conditioned by domestic institutions the empirical evidence suggests that while political and social openness have a significant impact in combating corruption given a free press the impact of such international forces are negligible in cases where press freedoms are low
