do faculty salaries rise with job seniority abstract previous research suggests that academic salaries fall with greater job seniority using a 1988 national survey we find that the return to seniority is positive over a lengthy employment period tenure status and academic rank also affect the return to seniority

learning wage dynamics and firm specific human capital we introduce a dynamic and fully strategic model of wage determination in the presence of firm specific human capital in this model human capital is interpreted as information we show that equilibrium exists and is efficient and that it gives rise to a unique distribution of the social surplus we show further that the equilibrium wage is determined by three factors consideration of these factors allows us to determine when and how the market mechanism enables the worker to capture some of the returns to firm specific human capital we relate our findings to the ongoing empirical debate concerning the return to tenure

measuring the pay disparity between typically female occupations and other jobs a bivariate selectivity approach the author of this study using a bivariate probit selectivity model with data from the 1984 panel survey of income dynamics finds that women in female dominated jobs earned 6 15 percent less than

an economic theory of avant garde and popular art or high and low culture artists face choices between the pecuniary benefits of selling to the market and the nonpecuniary benefits of creating to please their own tastes we examine how changes in wages lumpsum income and capital labor ratios affect the artist s pursuit of self satisfaction versus market sales using our model of labor supply we consider the economic forces behind the high low culture split why some artistic media offer greater scope for the avant garde than others why so many artists dislike the market and how economic growth and taxation affect the quantity and form of different kinds of art

a search interpretation of male female wage differentials a general equilibrium search framework is used to examine the role of gender differences in labor market behavior patterns e g quit rates for personal reasons in determining gender wage differentials for samples of high school and college graduates from the national longitudinal survey of youth nlsy these behavioral patterns are found to be significantly different across the sexes and account for 20 30 of the wage differentials in particular they play a key role in explaining the male female wage differential that remains after controlling for the gender composition across occupations

do workers remittances reduce the probability of current account reversals the authors combine the literature on financial crises in emerging markets and developing economies with that on international migrations by investigating whether the increasingly large flows of workers remittances can help reduce the probability of current account reversals the rationale for this stands in the great stability and low cyclicality of remittances as compared with other private capital flows these properties combined with the fact that remittances are cheap inflows of foreign currencies might reduce the probability that foreign investors suddenly flee out of emerging markets and developing economies and trigger a dramatic current account adjustment the authors find that remittances can have such a beneficial effect in particular they show that a high level of remittances as a ratio of gdp makes the relationship between a decreasing stock of international reserves over gdp and a higher probability of current account crises less stringent the same occurs though less neatly for the positive relationship between an increasing stock of external debt over gdp and the probability of current account reversals the results point also to a threshold effect of remittances the mechanisms just described are in fact much stronger when remittances are above 3 percent of gdp

gender differences in wages and job turnover among continuously employed workers the purpose of this paper is to determine whether a significant number of u s women work continuously during their early careers which women are likely to do so and how these women compare to men in terms of their interfirm mobility and earnings the data are from the young men and young women cohorts of the national longitudinal surveys of labor market experience nls continuous employment is by no means the norm among young women but it appears to be a growing trend in comparing starting wages of men and women we find that the wage gap is less pronounced among continuously employed workers than among the full sample in almost every race cohort schooling group and the gap is narrowing far more rapidly among the continuously employed excerpt

remittances and household consumption instability in developing countries this paper analyzes the impact of remittances on household consumption instability in a large panel of developing countries there are four main results first remittances significantly reduce household consumption instability second remittances play an insurance role by dampening the effects of various sources of consumption instability in developing countries natural disasters agricultural shocks discretionary fiscal policy systemic financial and banking crises and exchange rate instability third the stabilizing role played by remittances is stronger in less financially developed countries fourth the overall stabilizing effect of remittances is mitigated when remittances exceed 6 of gdp

rewards to academia the remuneration of vice chancellors and principals this paper models the financial remuneration to vice chancellors and principals at uk higher education institutions after describing the alternative theoretical underpinnings for the determination of pay an earnings function is estimated utilizing institutional and personal characteristics the model suggests only a partial linkage of managerial and performance related indicators to remuneration levels this suggests substantial scope for reorientation of rewards towards such indicators rather than relying on an efficiency wage this would appear particularly appropriate given the present and continued disclosure of this information together with the increased focus on performance indicators relating to teaching and research within the uk higher education sector

do economics departments with lower tenure probabilities pay higher faculty salaries the simplest competitive labor market model asserts that if tenure is a desirable job characteristic for professors they should be willing to pay for it by accepting lower salaries conversely if an institution unilaterally reduces the probability that its assistant professors receive tenure it will have to pay higher salaries to attract new faculty our paper tests this theory using data on salary offers accepted by new assistant professors at economics departments in the united states during the 1974 75 to 1980 81 period along with data on the proportion of new ph d s hired by each department between 1970 and 1980 that received tenure in the department or at a comparable or higher quality department within the first eight years of receipt of their ph d s we find evidence that supports the hypothesis that a tradeoff existed equally importantly departments that offered low tenure probabilities to assistant professors also paid higher salaries to their tenured faculty we attribute this to low tenur

remittances financial development and growth abstract despite the increasing importance of remittances in total international capital flows the relationship between remittances and growth has not been adequately studied this paper studies one of the links between remittances and growth in particular how local financial sector development influences a country s capacity to take advantage of remittances using a newly constructed dataset for remittances covering about 100 developing countries we find that remittances boost growth in countries with less developed financial systems by providing an alternative way to finance investment and helping overcome liquidity constraints this finding controls for the endogeneity of remittances and financial development does not depend on the particular measure of financial sector development used and is robust to a number of robustness tests including threshold estimation we also provide evidence that there could be an investment channel trough which remittances can promote growth especially when the financial sector does not meet the credit needs of the population

monetary policy and regional availability of debt financing the relative availability of bond and bank financing should affect the firm s external financing and investment decisions we define a measure that proxies for the regional borrowing inflexibility to substitute between bank and bond financing debt inflexibility debt inflexibility tilts the firm s financial structure towards equity and reduces investment the impact is stronger during the period of tight monetary policy particularly for smaller firms and firms without banking relationships debt inflexibility increases the sensitivity of cash holdings to cash flows reduces the likelihood of dividend payment and makes the firm more likely to pay equity in mergers and acquisitions

a panel data analysis of the fungibility of foreign aid the donor community has been increasingly concerned that development assistance intended for crucial social and economic sectors might be used directly or indirectly to fund unproductive military and other expenditures the link between foreign aid and public spending is not straightforward because some aid may be fungible this article empirically examines the impact of foreign aid on the recipient s public expenditures using cross country samples of annual observations for 1971 90 for the base sample of 14 developing countries it finds that aid is not fungible at the aggregate level and there is no associated tax relief increasing the number of countries however makes aid fungible moreover results based on the main sample indicate that aid is fungible in three out of five sectors examined developing country governments receiving earmarked concessionary loans for agriculture education and energy reduce their own resources going to these sectors and use them elsewhere only loans to the transport and communication sector are fully spent on the purposes intended by donors because most aid appears to be fungible the rate of return on a specific donor funded project tells little about the impact of that assistance a better approach may be to tie foreign aid to an overall public expenditure program that provides adequate resources to crucial sectors

early career work experience and gender wage differentials we estimate a wage model that includes an array of variables measuring the fraction of time worked during each year of the career this array fully characterizes past employment experience regardless of how sporadic it has been our model yields substantially higher estimated returns to experience and lower returns to tenure than do models that measure experience cumulatively and use the standard quadratic functional form we find that the data reject the standard model but fail to reject our model furthermore we find that 12 of the male female wage gap is due to differences in the timing of work experience

remittances and institutions are remittances a curse summary this paper addresses the complex and overlooked relationship between the receipt of workers remittances and institutional quality in the recipient country using a simple model we show how an increase in remittance inflows can lead to deterioration of institutional quality specifically to an increase in the share of funds diverted by the government for its own purposes in a cross section of 111 countries we empirically verify this proposition and find that a higher ratio of remittances to gdp leads to lower indices of control of corruption government effectiveness and rule of law even after controlling for potential reverse causality

worker effort decisions and efficient gender specific wage tenure profiles i introduction during the past thirty years women have increased their labor force participation female labor market intermittency has decreased and women s total labor market experience and years of tenure with the current employer have increased what these trends imply about the evolution of the gender gap in wages depends in part on gender differences in returns to tenure it is therefore surprising that economists have all but ignored the empirical finding that women have higher returns to tenure than do men over a significant portion of their working lives one reason why this finding has been ignored or treated as an anomaly may be the lack of theoretical constructs which predict an inverse gender gap in returns to tenure several labor market models predict that women should have lower returns to tenure than men human capital theory offers the most frequently cited explanation of flatter earnings profiles for female workers according to human capital theory gains from specialization and exchange lead to one household member specializing in home production and the other in market work since only women bear children historically the outcome of the exchange has been that women have specialized in home production indeed all surveys of time use indicate that women spend on average two to three times as long on housework as men as a consequence of this allocation women anticipate intermittent labor force participation and fewer years overall in the labor force than men this pattern too is borne out in national surveys which invariably find shorter average tenure and fewer total years of labor market experience for women than for men women typically have shorter completed job spells as well hall 1982 table 5 presents evidence that the gender gap in completed job duration is quite large he estimates that 63 8 percent of men but only 49 6 percent of women hold jobs with eventual tenure of at least five years with 37 3 and 15 1 percent of men and women respectively holding jobs with eventual tenure of at least twenty years because of the greater intermittency and shorter anticipated work history for women than men women will find it optimal to acquire less human capital than men 1 lesser quantities of general human capital tends to flatten both the observed earnings experience profile and the observed earnings tenure profile two factors contribute to this pattern first skills deteriorate during periods out of the labor market as in mincer and polachek 1974 which flattens the earnings experience profile for women relative to men second women anticipating discontinuous work histories select into occupations with flatter earnings profiles to minimize the penalty to labor force withdrawals as in polachek 1981 the effects of firm specific human capital on gender differences in wage tenure profiles vary across models for example kuhn 1993 constructs an elegant game theoretic model of gender differences in training and wages if women have a higher exogenous exit rate than men in equilibrium they will be placed in jobs with lower levels of firm specific training with a positive relation between training and productivity and a common share rate of the costs and benefits of specific training for men and women the wage tenure profiles of men will be steeper than those for women in contrast becker and lindsay 1994 argue that firm specific human capital leads to higher returns to tenure for women than men becker and lindsay assume that men and women have the same level of firm specific training however women have greater variance in their opportunity cost of remaining with a firm and so are more likely than men to separate inefficiently by giving women a greater share of both the costs and benefits of firm specific human capital through a steeper wage tenure profile firms reduce undesirable turnover although human capital arguments dominate the literature on gender differences in the labor market other models of wage growth predict flatter wage tenure profiles for women

determinants of health care expenditure in africa a cross sectional study the paper presents some quantitative evidence on the relationship between certain socioeconomic and demographic factors and per capita health care expenditure in africa first gnp per capita percentage of births attended by health staff and foreign aid received per capita together explained 78 3 of the variance in health care expenditure second per capita gnp is the most significant factor explaining differences in health care expenditure contrary to what has been found in comparisons of health care expenditure in the organization for economic cooperation and development oecd countries we found that the income elasticity is close to unity furthermore aid was consistently significant and positive in the three models estimated third variables such as crude birth rate and the population under 15 years of age as percentage of total population were not significant

a theory of wage dynamics a dynamic equilibrium model of long term implicit labour contracts under incomplete but symmetric information is developed workers are assumed to be risk averse and of unknown ability or productivity risk neutral firms learn as do workers about each worker s productivity by observing the worker s output over time it is shown that equilibrium contracts provide for wages which never decline with age and increase only when the worker s market value increases above his current wage in addition to characterizing the equilibrium wage contract we also derive some of its implications for the behaviour of aggregate wages across various groups of workers these implications explain some findings in the recent empirical literature on ageearnings profiles in particular our model can explain why earnings may be positively related to experience even after controlling for productivity as some empirical studies have indicated

workers remittances and the real exchange rate a paradox of gifts abstract we test the impact of workers remittances on the real exchange rate using a panel of 13 latin american and caribbean countries the analysis reveals that workers remittances have the potential to inflict economic costs on the export sector of receiving countries by reducing its international competitiveness our findings raise concerns parallel to those raised by dutch disease or resource boom models where resource discoveries result in real exchange rate appreciation and shifting of resources from the traded to the nontraded sectors of the economy

corruption and the shadow economy an empirical analysis this paper analyzes the influence of the shadow economy on corruption and vice versa we hypothesize that corruption and the shadow economy are substitutes in high income countries while they are complements in low income countries the hypotheses are tested for a cross section of 98 countries our results show that there is no robust relationship between corruption and the size of the shadow economy when perceptions based indices of corruption are used employing an index of corruption based on a structural model however corruption and the shadow economy are complements in countries with low income but not in high income countries

how do journal quality co authorship and author order affect agricultural economists salaries utilizing an original data set containing annual salaries and peer reviewed publication histories for 326 faculty members from top ranked ph d granting programs we examine the labor market for academic agricultural economists the results suggest that higher quality publications have a greater impact on annual earnings that sole authored articles have a higher return than multi authored articles and that no wage premium exists for being the lead author of a non alphabetic article

reputation and earnings the roles of quality and quantity in academe we examine the determinants of professional reputation does quantity of exposures raise reputation independent of quality does quality of the most important exposure have extra effects on reputation in a very large sample of academic economists there is little evidence that a scholar s most influential work provides any extra enhancement of reputation quality rankings matter more than absolute quality quantity has a zero or even negative effect on proxies for reputation data on salaries however show positive effects of quantity independent of quality we test explanations for the differences between the determinants of reputation and salary jel l14 j31

interfuel and interfactor substitution in ontario manufacturing 1962 82 the extent of substitutability between energy and the other factors i e labour and capital is an extremely important question and quite central to energy policy planning and analysis this paper addresses this question for the ontario manufacturing sector the theoretical model utilized in this analysis is the two stage translog production frontier the model was estimated for seven manufacturing sectors using four disaggregated energy inputs and labour and capital the model was estimated by the fiml technique for the period 1962 82

product market imperfections job content differences and gender employment discrimination at the management level some evidence from the canadian manufacturing sector in 1971 and 1981 this paper presents a regression model of the relative employment level of female managers using data for 1971 and 1981 on a forty one industry sample drawn from the canadian manufacturing sector the object of the analysis is to test the neoclassical proposition that employment discrimination here against females is fostered by imperfect product market conditions in addition the model allows for the open nature of the canadian economy and for interindustry differences in the job and skill content of managerial occupations the results support the neoclassical view and as well emphasize the importance of post secondary education to the employment of females at the management level

a study of wages and reliability this article studies the role of reliability on the wage rate reliability is defined in the sense of showing up for scheduled work over an extended period just as reliability is an important determinant of product prices a worker s reliability ought to be an important determinant of his or her wage moreover while workers are not conveniently packaged by brand name firms form expectations about reliability across identifiable groups of workers and thus effectively attach brand names to workers based on their observable characteristics a worker s wage depends on his own track record and the reputation for reliability of his identifiable group using robust measures of reliability i find that observed reliability and expected reliability substantially affect the wage rate and that about half of the gender wage gap can be explained by differences in expected reliability between men and women in the workforce

the effect of collective bargaining on salaries in higher education using data from a 1977 survey of faculty from 158 u s colleges and universities the author estimates that the proportional salary advantage to unionized faculty members was typically less than two percent that differential varied considerably however with the length of time the institution had been organized in addition unionization increased the return to seniority and decreased the return to several measures of merit including number of publications and general post degree experience

the effects of competition and equal treatment laws on gender wage differentials discrimination if it is inefficient can be eliminated by competition in most countries it is also forbidden by law this paper evaluates the influence of economic and legal factors on the portion of male female wage differentials that is not explained by other worker characteristics and may be due to discrimination we use a new international data set of suitable gender wage gap measures constructed from the results of existing studies meta analysis of the data shows that increased competition and adoption of international conventions concerning equal treatment laws both reduce gender wage gaps while legislation that prevents women from performing strenuous or dangerous jobs tends to increase it doris weichselbaumer and rudolf winter ebmer

sex discrimination and product market competition the case of the banking industry this paper examines the relationship between product market competition and employment discrimination using an especially constructed data set that links microeconomic data on female employment with measures of market concentration in the banking industry the use of firm specific data drawn from this one industry allows estimation of this relationship in a manner that avoids the problems of interindustry differences that have troubled previous studies the results provide strong support for a negative relationship between market concentration and the relative employment of women further we find that individual market shares are unrelated to female employment suggesting that the relationship is due primarily to differences across markets rather than individual firms

does raiding explain the negative returns to faculty seniority i introduction economists have studied various aspects of faculty mobility research shows that turnover is greater among nonunion faculty rees 1994 female faculty average slightly more employers than male faculty barbezat and hughes 2001 ginther and kahn 2004 1 the responsiveness of turnover to relative pay diminishes with rank ehrenberg kasper and rees 1991 and research productivity enhances prospects for upward mobility ault rutman and stevenson 1979 1982 coupe smeets and warzynski 2005 still questions remain unanswered where do faculty go when they leave a university how does faculty turnover vary with time at a university what percentage of faculty move upward and what percentage move downward because of tenure denials or the prospect of being turned down for tenure the present article contributes to our understanding of these issues but its primary objective was to use data on faculty mobility to provide insights on another issue returns to academic seniority the negative returns to seniority that many studies find are commonly attributed to one of two factors 2 the first view is that negative returns reflect monopsony power on the part of universities faculty with high mobility costs acquire high seniority and because they are unlikely to move they are paid less than equally productive faculty that employers view as more likely to leave a competing explanation is that highly productive faculty are raided according to this story returns to seniority are biased negatively because faculty with high seniority tend to have low unmeasured productivity the best faculty are bid away moving on to better jobs those who remain are the faculty without outside offers and the negative returns estimated for senior faculty actually reflect a penalty for low unmeasured productivity rather than a true penalty for seniority the raiding story has several implications first estimated returns to seniority should become less negative the more fully the productivity is measured second estimated returns should be less negative once we control for faculty who are bid away finally and of particular importance estimated returns to seniority should not be negative for faculty who are bid away the faculty for whom unmeasured productivity is presumably high with the right data set these hypotheses can be tested rejection of the raiding hypothesis would provide tacit evidence of monoposony in academic markets 3 this article contributes to the literature in several ways it is the first research to directly test the raiding hypothesis it provides a detailed look at faculty mobility in one segment of the academic labor market it extends and improves bratsberg ragan and warren 2003 in the following ways it expands the sample to cover three decades of faculty pay records it includes additional controls for productivity number and types of books recent and prospective articles and so forth resulting in the most complete specification of research productivity to date and it allows for heterogeneity in the seniority penalty via phd pedigree and direction of move finally it tests for the possibility that the academic job market does a better job of matching faculty and universities in recent years as might be expected because of the information revolution the sample consists of five public phd granting universities in the midwest we track all tenure track economics faculty employed in these universities over a 30 yr period we measure their productivity their pay and their mobility as such the study provides a rich and detailed investigation of one subset of economics programs it is possible that mobility may be greater in urban areas where faculty can more readily obtain alternative employment without relocating and prior research indicates that pay structures depend on the university s stature and its relative emphasis on research and teaching

do international migration and remittances reduce poverty in developing countries summary few studies have examined the impact of international migration and remittances on poverty in the developing world this paper fills this lacuna by constructing and analyzing a new data set on international migration remittances inequality and poverty from 71 developing countries the results show that both international migration and remittances significantly reduce the level depth and severity of poverty in the developing world after instrumenting for the possible endogeneity of international migration and controlling for various factors results suggest that on average a 10 increase in the share of international migrants in a country s population will lead to a 2 1 decline in the share of people living on less than 1 00 per person per day after instrumenting for the possible endogeneity of international remittances a similar 10 increase in per capita official international remittances will lead to a 3 5 decline in the share of people living in poverty

workers compensation and moral hazard in tunisia abstractmoral hazard is a problem of asymmetric information that plays a central role in numerous contractual relationships and may lead to suboptimal resource allocation both ex ante and ex post moral hazard problems in workers compensation wc have been extensively analysed in developed countries the main objective of this paper is to test the presence of ex post moral hazard in the tunisian context to our knowledge this is the first analysis on this topic in a developing country tunisia it is particularly important to study moral hazard problems in developing countries since the negative impacts of such problems could be exacerbated in the developing world dionne and st michel 1991 have developed a methodology for testing for the presence of ex post moral hazard in the context of a more generous wc regime in quebec the tunisian institutional context that we study is similar to that prevailing in quebec that is in 1995 there was a significant increase in the generosity of the wc regime

job duration seniority and earnings an important stylized fact about labor markets is that workers with longer seniority with their current employer have higher earnings than other workers with the same total labor market experience this study shows that workers in longer jobs earn more throughout than workers in a series of shorter jobs and that the measured positive cross sectional return seniority is largely a statistical artifact due to the correlation of seniority with an omitted variable representing the quality of the worker the job or the worker employer match the implication is tha t earnings do not in fact rise very much with seniority copyright 1987 by american economic association

what matters most teaching or research empirical evidence on the remuneration of british academics this paper examines the impact of productivity on pay within academia drawing upon a detailed dataset of academics from five old established universities results outline the importance of publication grant receipt and teaching quality in the determination of pay a large financial penalty to time out of the profession is revealed which with productivity variables explains away the gender salary gap the relationship between teaching and research is investigated and we find some evidence in support of the hypothesis that productive researchers are successful teachers results on reservation salary suggest that the best academics are willing to stay within the profession

gender and racial earnings differentials in academic labor markets this study estimates earnings differentials across racial and gender groups among college faculty and decomposes these differentials into the components attributable to differences in individual and institutional characteristics and that which remains unexplained we find that white females earn approximately 4 percent less than white males black males earn 7 4 percent more black females earn one percent more hispanic males earn 2 7 percent more hispanic females earn 1 7 percent less and asian males earn 7 7 percent more than comparable white males we also find a significant earnings penalty for being a naturalized citizen or noncitizen versus an u s born citizen

the wage effects of cumulative job mobility this analysis of data from the national longitudinal survey of youth shows that cumulative job mobility had statistically significant effects on wages in the years 1979 88 the direction of the wage effects positive or negative and their magnitude varied depending on the type of cumulative mobility examined employee initiated versus employerinitiated separations economic versus family related quits layoffs versus discharges the results also indicate that although men and women had different mobility histories men for example had been discharged more often than women and women had quit for family related reasons more often than men the wage effects of each type of cumulative mobility economic quits family related quits layoffs and discharges were similar for men and women tn this paper we examine the impact of cumulative job mobility on the subsequent wages of young men and women most previous work on this subject has focused on the impact of specific mobility events such as quits or layoffs rather than on the impact of total job history on wages researchers looking at single mobility decisions have consistently reported evidence that a change in employers does affect a worker s subsequent wage therefore it is reasonable to ask whether the impact ofjob change is cumulative that is does a worker s current wage reflect the impact of all past mobility decisions quits layoffs and discharges also since most of the

works councils wages and job satisfaction we investigate the effects of works councils on employees wages and job satisfaction in general and for subgroups with respect to sex and occupational status making use of a german representative sample of employees we find that employees who move to a firm with a works council report increases in job satisfaction but do not receive particular wage increases especially the job satisfaction of female employees is affected by a change in works council status however we do not find support for the hypothesis that the introduction of a works council itself increases wages or job satisfaction for the employees staying at the firm

are there gender differences in the job mobility patterns of academic economists labor economic theory posits that job mobil ity should affect worker salaries the degree to which this holds for academic faculty has received considerable attention prior empirical studies have estimated log wage regressions that control for both years of total work experience and years of seniority at the current institution in an effort to determine whether negative returns to seniority exist in academic labor markets for example bernt bratsberg james ragan and jim warren 2003 and william moore robert turnbull and geoffrey newman 1998 for aca demic economists michael ransom 1993 kevin hallock 1995 and emily hoffman 1976 for specific institutions debra a barbezat and michael r donihue 1998 and barbezat 1989 for

international migration remittances and household investment evidence from philippine migrants exchange rate shocks how do households respond to overseas members economic shocks overseas filipinos in dozens of countries experienced sudden heterogeneous changes in exchange rates during the 1997 asian financial crisis appreciation of a migrant s currency against the philippine peso leads to increases in household remittances from overseas the estimated elasticity of philippine peso remittances with respect to the exchange rate is 0 60 positive migrant shocks lead to enhanced human capital accumulation and entrepreneurship in origin households child schooling and educational expenditure rise while child labour falls households also work more hours in self employment and become more likely to start relatively capital intensive household enterprises

cyclicality of credit supply firm level evidence abstract we quantify fluctuations in bank loan supply in the time series by studying firms substitution between loans and bonds using firm level data any firm that raises new debt must have a positive demand for external funds conditional on the issuance of new debt we interpret firms switching from loans to bonds as a contraction in bank credit supply we find strong evidence of this substitution at times that are characterized by tight lending standards depressed aggregate lending poor bank performance and tight monetary policy we show that this substitution behavior has strong predictive power for bank borrowing and investments by small firms

decomposing energy demand across briic countries energy plays an important role within the production technology of fast emerging economies such that firms reaction to changes in energy prices provides useful information on factor productivity and factor intensity as well as the likely outcome of energy policy initiatives among other things drawing on duality theory this paper decomposes changes in energy demand into substitution and output effects using annual sector level production data for brazil russia india indonesia and china briic for the period 1995 2009 unlike previous studies this study analyzed the economic properties of the underlying production technology results indicate that changes in energy demand are strongly dominated by substitution effects more importantly an intriguing finding that emerges from our analysis is the role of economies of scale and factor accumulation as opposed to technical progress in giving rise to the growth performance of sampled economies

reputational capital and academic pay geoffrey k turnbull i introduction economists continue to have a strong interest in academic labor markets as the steady stream of earnings studies over the past several decades readily attests the academic labor market draws the attention of economists not only because it is a topic of direct personal interest but also because it presents an opportunity to examine general theories of labor markets in a context with which the researcher has intimate experience nonetheless important questions about how the market values research teaching and service remain unanswered to what extent does the market reward quality versus quantity of published research or team production in the form of co authorship furthermore how durable is reputational capital for individuals whose research productivity diminishes during their career ultimately these questions relate in one way or another to the nature of the incentive structure faced by academic economists we provide new evidence concerning the role of research quality co authorship administrative service and teaching performance in the production of reputational capital in addition we explore the question of the durability of reputational capital once some of these activities cease we assume that the quantity and quality of published research largely determines an individual s reputational capital in the external market to help us sort out the separate effects on reputational capital of both the quality and quantity of research activity we measure research quality by both journal quality and career citations employing an interactive quantity quality term a related question concerns the role of team production in building an individual s reputational capital do individuals receive differential returns to publishing single authored versus co authored research papers this is an interesting question in light of the substantial increase in co authorship over the last few decades 1 one explanation of this trend is that the academic market has presented scholars with increasing opportunities for specialization in the production of knowledge and that team production involves the combination of complementary skilled researchers if team production reflects complementarities in the production of research we should observe little difference in the returns to single versus co authored work another explanation is that co authorship involves the combination of substitute skilled researchers so that co authorship presents a way for individuals to reduce their research efforts without reducing their individual measured research output to the extent that co authorshi p represents such substitution the market should fully discount the returns to multiple authored papers in this article we also move beyond identifying the factors that enhance an individual s reputation in the market to study the question of the durability of reputational capital some individuals quit publishing once they are tenured or promoted while others experience lengthy but temporary breaks in their flow of research output we examine the potential penalties associated with gaps in research output providing the first empirical evidence concerning the durability of reputational capital for academic economists in order to ensure that our analysis deals with these issues in a way that is most relevant to a large portion of the market for academic economists we use data from several research universities but restrict the sample frame to a single discipline economics much of the previous work estimating how publications or other factors affect academic salaries typically use data from a single university with earnings equations estimated across disciplines restricting the sample to a single discipline has the additional advantage of reducing potential heterogeneity problems associated with measuring productivity across disciplines in addition our data enable us more thoroughly to explore the empirical issues in the debate since they permit more precise measures of the past and current productivity of individuals engaged in comparable work

remittances and public finances evidence from oil price shocks we study the effect of inflowing remittances a major source of capital for many countries on tax revenues and tax policy instrumenting remittances with changes in the oil price interacted with a country s distance to oil producing countries we find that remittances have a large positive effect on vat revenues but no effect on income tax revenues this suggests that remittances often escape the income tax but can be taxed via consumption we further show that tax policy is responsive to shocks in incoming remittances remittances make the adoption of vat systems more likely and they lead to lower vat rates and higher income tax rates

remittances institutions and economic growth summary there is considerable debate regarding the relative contribution of international migrants remittances to sustainable economic development while officially recorded remittances to developing countries have increased over the last decade research has not come to a consensus over whether remittances have a positive or negative impact on long run growth this paper argues that contradictory findings have emerged when looking at the remittances growth link because of an omitted variable bias specifically remittances will be more likely to contribute to longer term growth in countries with higher quality political and economic policies and institutions

revisiting the seniority wage effect for faculty abstract this study uses 1999 national data to derive estimates of the effect of seniority on faculty salaries seniority has a positive effect on salary but varies by union status rank job mobility and inclusion of faculty productivity measures

do wages rise with job seniority many previous studies have found a strong positive effect of job seniority tenure on wages this paper re examines the evidence using a simple instrumental variables scheme to deal with the fact that tenure is likely to be related to unobserved individual and job characteristics that affect the wage we use the variation of tenure over a given job match as the principal instrumental variable for tenure the variation in tenure over the job is uncorrelated by construction with the fixed individual and job match specific components of the error term of the wage equation our main finding is that the partial effect of tenure on wages is small and that general labour market experience and job shopping account for most wage growth over a career the strong cross section relationship between tenure and wages is due primarily to heterogeneity bias prior researchers see mincer and jovanovic 1981 bartel and borjas 1981 borjas 1981 cline 1979 and mellow 1981 and many others have established that job seniority has a strong positive relationship with wage rates in a cross section or a cross section time series of individuals in this paper we re evaluate the evidence concerning the partial effects on wages of job seniority tenure and total labour market experience the extent to which wages rise with tenure is important for several reasons first and foremost the wage tenure profile is a fundamental question about the structure of earnings over careers second the wage tenure profile is a key determinant of the extent to which the earnings power of individuals is tied to specific jobs and it is important for assessment of the losses suffered by displaced workers hamermesh 1984 third evidence that wages rise with job tenure has been used to explain the decline in quits with tenure since the wage growth on the current job lowers the probability that the worker will locate a superior alternative a growing theoretical literature surveyed in parsons 1984 has taken the evidence of a strong wage tenure profile at face value and sought to provide an explanation for the relationship the most prominent explanation is the theory of specific human capital oi 1962 becker 1962 mincer 1974 parsons 1972 kuratani 1973 and hashimoto 1980 in which the growth of wages with tenure holding experience constant is attributed to the worker s share of investments in firm specific skills more recently lazear 1981 has presented a supervision model of wage growth in which firms defer compensation as a means of inducing workers not to shirk freeman 1977 and harris and holmstrom 1982 provide an explanation for wage growth based on an insurance motive salop and salop 1976 nickell 1976 and guasch and weiss 1982 present adverse selection models of wage growth in which firms use a wage tenure profile as a

fame and the fortune of academic economists how the market rewards influential research in economics we analyze the pay and position of 1 009 faculty members who teach in doctoral granting economics departments at fifty three large public universities in the united states using the web of science we have identified the journal articles published by these scholars and the number of times each of these articles has been subsequently cited in published research articles we find that research influence as measured by various measures of total citations is a surprisingly strong predictor of the salary and the prestige of the department in which professors are employed we also examine how coauthorship is rewarded by the market

do remittances lead to a public moral hazard in developing countries an empirical investigation abstract this article tests the hypothesis that in a context of bad governance remittance inflows strongly reduce public spending on education and health in receiving countries a phenomenon called the public moral hazard problem using a large sample of 86 developing countries over the period 1996 2007 and after factoring in the endogeneity of remittances the results suggest a negative impact of remittances on public spending on education and health when governance is bad in remittance dependent economies

energy and capital substitutes or complements a note on the importance of testing for non neutral technical progress this note investigates the importance of testing the validity of the hicks neutral technical progress assumption in the context of examining the substitutability or complementarity between capital labour and energy in the uk industrial sector it is found that the hypothesis of neutral technical progress must be rejected in favour of the non neutral hypothesis with technical progress thus biased to using both capital and energy but to saving labour in addition it is found that all three factors are substitutable for one another when non neutral technical progress is modelled

academic pay in the united kingdom and the united states the differential returns to productivity and the lifetime earnings gap this paper estimates earnings functions for two samples of u k and u s academic economists despite significant differences in compensation schemes a comparably specified human capital earnings model does a good job explaining earnings variations for academic economists in both countries our estimates suggest that rewards for research are more immediate and direct in the united states because of the national salary scale the payoffs to experience and seniority are greater and the payoffs to research are lower in the united kingdom than in the united states after adjusting for productivity and demographic factors we find that u s economists are paid approximately 40 more than otherwise equivalent economists in the united kingdom simulating career age earnings profiles for both markets we find that the earnings gap widens with experience for relatively productive research economists and may even narrow with age for relatively less productive research economists nevertheless the cumulative lifetime earnings foregone are substantial for research and nonresearch economists in the united kingdom

energy conservation in electricity generation a case study of the electricity and water industry in kuwait this paper has examined possibilities of energy conservation in the generation of electricity and water in kuwait this has been done through analysing the underlying production structure by employing a translog flexible cost function and using series data the results show that in the absence of changes in factor prices fuel intensity of electricity and water is expected to increase with increase in output furthermore capital and fuel are found to be substitutes overall the evidence suggests that energy conservation can be achieved by using fuel prices as instruments this is likely to induce demand for new capital and hence promote productivity gains

which journal rankings best explain academic salaries evidence from the university of california the ranking of an academic journal is important to authors universities journal publishers and research funders rankings are gaining prominence as countries adopt regular research assessment exercises that especially reward publication in high impact journals yet even within a rankings oriented discipline like economics there is no agreement on how aggressively lower ranked journals are down weighted and in how wide is the universe of journals considered moreover since it is typically less costly for authors to cite superfluous references whether of their own volition or prompted by editors than it is to ignore relevant ones rankings based on citations may be easily manipulated in contrast when the merits of publication in one journal or another are debated during hiring promotion and salary decisions the evaluators are choosing over actions with costly consequences we therefore look to the academic labor market using data on economists in the university of california system to relate their lifetime publications in 700 different academic journals to salary we test amongst various sets of journal rankings and publication discount rates to see which are most congruent with the returns implied by the academic labor market jel a14 i23 j44

energy and capital substitutes or complements some results for the uk industrial sector this paper investigates the substitutability or complementarity possibilities between capital labour and energy in the uk industrial sector with particular attention to the captial energy relationship it is found using the translog cost function approach that capital and labour as well as energy and labour are substitutes however capital and energy are found to be complements

earnings differentials and market structure theoretical models suggest that market structure may influence the magnitude of earnings differentials and or discrimination observed in the marketplace empirical results with regard to wage differentials and labor force participation patterns have been mixed most wage differential studies have focused on males due to difficulty in obtaining reliable data for women and to the sample selection problem of women s labor force participation decisions this paper characterizes market structure by four categories regulated nonprofit government and nonregulated industries within these structural categories earnings differentials are examined for men and women adjusting for race occupational stratification and sample selection bias

seniority and monopsony in the academic labor market workers with high seniority usually have higher wages than workers with low seniority and the same total labor marke t experience in contrast the results of this paper indicate that higher seniority is associated with lower salaries for university professors the author documents this finding for national surveys a nd individual institutions and explains it as due to monopsonistic discrimination by employers copyright 1993 by american economic association

the impact of green innovation on energy intensity an empirical analysis for 14 industrial sectors in oecd countries abstract this paper analyses the impact of green innovation on energy intensity in a set of 14 industrial sectors in 17 oecd countries over the 1975 2005 period we create a stock of green patents for each industrial sector and estimate a translog cost function to measure the impact of green innovation on energy intensity next to other factors such as input substitution and autonomous technical change we find that green innovation has contributed to the decline in energy intensity in the majority of sectors the median elasticity of energy intensity with respect to green patenting is estimated at 0 03 in our sample hence a 1 increase in green patenting activities in a given sector is associated with a 0 03 decline in energy intensity the magnitude of the effect is robust across various specifications and is larger in more recent years a decomposition exercise shows that overall half of the decrease in energy intensity over the sample period is related to changes in input prices and half to changes in production technologies

monopsony in the labor market this paper surveys recent theoretical and empirical research on monopsony in labor markets broadly defined as upward sloping labor supply to an employer we compare older monopsony models based on small numbers of employers with newer models based on labor market frictions such as moving costs and search we also compare older econometric approaches that focus on static wage concentration relationships with newer approaches that focus on dynamics our review of empirical estimates suggests that monopsony power based on small numbers of employers is probably rare but occasionally large while monopsony power based on frictions is probably widespread but small on average

is migration a good substitute for education subsidies assuming a given educational policy the recent brain drain literature reveals that skilled migration can boost the average level of schooling in developing countries this paper introduces educational subsidies determined by governments concerned by the number of skilled workers remaining in the country the theoretical analysis shows that developing countries can benefit from skilled emigration when educational subsidies entail high fiscal distortions however when taxes are not too distortionary it is desirable to impede emigration and subsidize education the authors investigate the empirical relationship between educational subsidies and migration prospects obtaining a negative relationship for 105 countries based on this result the analysis revisits the country specific effects of skilled migration upon human capital the findings show that the endogeneity of public subsidies reduces the number of winners and increases the magnitude of the losses

family labour supply and labour market segmentation this paper examines the differences in individuals labour supply decisions in different segments of the labour market it tests one of the main hypotheses of the dual labour market theory that the labour market can be divided into at least two segments and also whether the family labour supply decisions of individuals differ in the two segments the possibility of individuals wage rates depending on the number of hours worked is recognized and a model is developed in which both the wage rates and hours of work of individuals are jointly determined with the personal income tax system as an intervening variable since hours of labour supply depend on the post tax wage rate whereas if the marginal product of labour is a positive function of hours worked this affects the pre tax wage rates other alternative wage functions are specified and a simultaneous equations labour supply model using three stage least squares 3sls procedure is estimated the results indicate that there was sample selectivity bias

effect of remittances on poverty and financial development in sub saharan africa summary this paper assesses the effect of the steadily growing remittance flows to sub saharan africa though the region receives only a small portion of the total recorded remittances to developing countries and the volume of aid flows to sub saharan africa swamps remittances this paper finds that remittances which are a stable private transfer have a direct poverty mitigating effect and promote financial development these findings hold even after factoring in the reverse causality between remittances poverty and financial development the paper posits that formalizing such flows can serve as an effective access point for unbanked individuals and households

deforestation and the real exchange rate deforestation is a phenomenon that has largely been concentrated in the developing world we construct a theoretical model of deforestation that focuses on the factors affecting the incentives to transform forested land into agricultural land we show that i lower discount rates and stronger institutions decrease deforestation ii depreciations in the real exchange rate increase deforestation in developing countries whereas the opposite obtains in developed countries iii paradoxically better institutions may exacerbate the deleterious impact of depreciations in developing countries these hypotheses are tested on an annual sample of 101 countries over the 1961 1988 period and are not rejected by the data our results suggest that short term macroeconomic policy institutional factors and the interaction between the two are potentially important determinants of environmental outcomes
