intraurban residential mobility the role of transactions costs market imperfections and household disequilibrium abstract this paper presents a model of household residential search and mobility that focuses on microeconomic elements of household behavior and incorporates housing market features the model is cast explicitly in terms of a rigorous model of housing demand allowing the benefits from moving to be measured as the compensating income variation of the potential change in consumption the empirical results indicate that large changes in economic variables such as income and prices produce only small potential gains from moving and that a major factor in the moving decision is the magnitude of search and moving costs

citations and incentives in academic contests i consider a contest between scholars on the basis of three popular indices of citation there exist equilibria in which there are more and better quality papers in the total citations contest than in the h index contest in some cases the total citations contest yields the same quality of papers but more papers than the euclidean contest as the cost of writing a paper increases the h index is inferior to the total citations index in both the quality and quantity of papers this result is partly driven by how the number of papers constrains how the h index counts citations jel d72

income redistribution in a common labor market when households are mobile among jurisdictions income redistribution by individual jurisdictions creates fiscal externalities a model of interjurisdictional migration is used to study the nature of this redistributive externality analysis of optimal redistribution and optimal corrective subsidies from higher level governments shows that benefit levels for the recipients of income transfers and tax rates on mobile taxpayers should be equalized across jurisdictions a system of jurisdictions with a common labor market can achieve welfare improvements through coordination of domestic redistributive policy or through the intervention of a higher level government copyright 1991 by american economic association

an empirical analysis of intergovernmental tax interaction the case of business income taxes in canada both federal and provincial governments in canada levy corporate taxes on busi nesses in their jurisdictions which potentially gives rise to horizontal and vertical tax exter nalities within the federation using a simple model of interdependent tax choices we estimate tax setting functions for the federal government ontario quebec and an aggregate of the remaining eight provinces we find evidence of significant vertical and horizontal tax inter actions provincial tax rates respond negatively to the federal tax rate while at least some provinces increase their tax rates in response to increases in the tax rates of other provinces

how to avoid borrowed plumes in academia abstract publications in top journals today have a powerful influence on academic careers although there is much criticism of using journal rankings to evaluate individual articles we ask why this practice of performance evaluation is still so influential we suggest this is the case because a majority of authors benefit from the present system due to the extreme skewness of citation distributions performance paradox effects aggravate the problem three extant suggestions for reforming performance management are critically discussed we advance a new proposal based on the insight that fundamental uncertainty is symptomatic for scholarly work it suggests focal randomization using a rationally founded and well orchestrated procedure

residential mobility with job location uncertainty abstract this paper investigates the relationship between job changes and residential mobility a job change may be prompted by reasons unrelated to factors associated with housing consumption however a job change may lead to an adjustment to housing consumption i e residential relocation previous studies find that job relocations are positively associated with residential mobility this paper departs from previous studies by looking at the effects of an uncertain future job location on residential mobility and mobility expectation it is conjectured that with the existence of costs of residential mobility a household head s likelihood for changing jobs in the future dampens the household s propensity to move but encourages the formation of mobility expectation these conjectures are examined empirically using data from the panel study of income dynamics and they are confirmed

tax structure in a federation abstract does national taxation of a base influence the degree to which the local government will use the same tax base does the tax rate chosen by one local government influence the choices made by another local government the theoretical answer to these questions is often in the affirmative because of vertical and horizontal externalities that result when several governments are operating at the same time in a fiscal system however little empirical information is available this paper estimates the impact of horizontal and vertical externalities on the choice of tax rates by local governments operating in a federation higher national income tax rates and lower poverty rates are found to lead to lower local income tax rates

on the job search behavior the importance of commuting time using search theory we show that job search effort is increasing and under some conditions convex in commuting time we show that the effect of commuting time on job search effort levels may be small in case of uncertainty caused by future job and residential moving behavior thus we provide a microeconomic explanation for the finding that commuters behave as if they are footloose our empirical analysis supports the behavioral implications of the model for the netherlands surprisingly we do not find any evidence that the effect of commuting time on search behavior depends on the commuters socioeconomic characteristics

residential mobility and job changes under uncertainty abstract this paper empirically investigates households residential mobility and job change decisions under uncertainty we allow households degree of risk aversion to be a confounding factor in the joint decision of residential mobility and job changes using panel data to estimate a random effects multinomial probit model of households joint decision of residential and job mobility our empirical results show that risk aversion discourages a household from making any changes moreover when compared to single changes in either job or residential locations risk aversion is more discouraging for joint changes to more central residential locations and less discouraging for joint changes to more distant residential locations these effects are statistically significant albeit small in magnitude our empirical results demonstrate the uncertainty does play a role in households job and residential mobility decisions

an updated ranking of academic journals in economics we conduct an update of the ranking of economic journals by kalaitzidakis mamuneas and stengos 2003 however our present study differs methodologically from that earlier study in an important dimension we use a rolling window of years between 2003 and 2008 for each year counting the number of citations of articles published in the previous ten years this allows us to obtain a smoother longer view of the evolution of rankings in the period under consideration and avoid the inherent randomness that may exist at any particular year using this framework we proceed to examine the relative ranking of the canadian journal of economics over time we find the canadian journal managed not only to maintain its relative position but to also improve it over time

uncertainty measures for economics journal impact factors academic economists appear to be intensely interested in rankings of journals institutions and individuals yet there is little discussion of the uncertainty associated with these rankings to illustrate the uncertainty associated with citations based rankings i compute the standard error of the impact factor for all economics journals with a five year impact factor in the 2011 journal citations report i use these to derive confidence intervals for the impact factors as well as ranges of possible rank for a subset of thirty journals i find that the impact factors of the top two journals are well defined and set these journals apart in a clearly defined group an elite group of 9 11 mainstream journals can also be fairly reliably distinguished the four bottom ranked journals are also fairly clearly set apart for the remainder of the distribution confidence intervals overlap and rankings are quite uncertain jel a14

does the median voter model explain the size of government evidence from the states despite an attempt by its own authors it is difficult to argue that the influential model of the size of government developed by meltzer and richard 1981 has had convincing empirical backing in this paper we adapt that model to a model of state government size the main testable hypothesis is that as income inequality grows government size as measured by the percentage of income devoted to government redistribution grows we test the model using panel data from the us states from 1979 1991 in contrast to the results found by meltzer and richard 1983 we find little evidence to support the model the results are robust to several model specifications and estimation techniques

the consequences of overlapping tax bases for redistribution and public spending in a federation tax and expenditure policies are studied in a federation with imperfectly mobile households states implement a linear progressive tax and supply a public good a vertical fiscal externality reflecting the effect of state policies on federal revenues provides an incentive for state taxes to be too progressive a horizontal fiscal externality causes nonoptimal state taxes and expenditures because of the migration effect the federal government implements its own linear progressive tax and makes transfers to the states the federal government can nullify both externalities by appropriate fiscal policies and redistributive taxation can be decentralized to the states c 1998 elsevier science s a

european economics an analysis based on publications in the core journals abstract in this paper we provide a ranking of european economics institutions and countries based on publications in a core set of 10 economic journals from 1991 to 1996 we find that the three leading universities in europe are the london school of economics tel aviv university and oxford university while the three top ranked countries are the u k france and israel

one swallow doesn t make a summer new evidence on anchoring effects some researchers have argued that anchoring in economic valuations casts doubt on the assumption of consistent and stable preferences we present new evidence that explores the strength of certain anchoring results we then present a theoretical framework that provides insights into why we should be cautious of initial empirical findings in general the model importantly highlights that the rate of false positives depends not only on the observed significance level but also on statistical power research priors and the number of scholars exploring the question importantly a few independent replications dramatically increase the chances that the original finding is true

scholarships citations and salaries economic rewards in economics while substantial attention has been paid to the determinants of academics earnings 5 7 8 14 15 this literature has by implication suggested that the mere fact of having spent more time in the profession and the publication of more scholarly articles and books are the major determinants of salary differences our purpose here is to introduce a new determinant the quality of one s scholarly research measured by the frequency of references to that work as an additional objective measure of productivity we expect that this proxy for the extent of a scholar s influence on the work of other researchers is rewarded by the market in addition to giving a more complete picture of the determination of salaries in academic labor markets our approach should be useful in establishing a better framework for the evaluation of issues of discrimination in such markets than has been presented before 2 9

income redistribution in a federal system the question of the appropriate level of government to undertake income redistribution is receiving renewed attention from economists the standard argument about the issue might be summarized as follows 1 interstate migration of taxpayers and transfer recipients raises the cost to voters of income redistribution at the state level above the cost at the federal level 2 statewide redistribution confers spillover benefits to residents of other states 3 therefore as compared with a national system decentralized responsibility for income redistribution yields both less redistribution and less than the socially optimal amount of income redistribution the purpose of this paper is only to question step 1 of the above argument of course readers who accept the assumptions of the standard argument may conclude that the possible weakening of step 1 of that argument reduces the likelihood that its conclusion holds the paper argues that the cost of redistribution faced by state residents may in fact be lower at the state level than at the national level because their federal tax obligations fall as the state redistributes more income thus part of the cost of redistribution at the state level can be exported to residents of other states the state s federal tax bill falls when taxable incomes in the state are reduced by increased redistribution deductibility of state taxes enhances this result but is not necessary for it to demonstrate the proposition without adding unnecessary complication a simple model of income redistribution is described in which governments at all levels use linear tax transfer schedules to redistribute income the single government case is considered first then two levels of government are introduced and finally migration is allowed it is shown that without migration state costs are never greater than national costs of redistribution as long as redistribution reduces total money income when migration is allowed the result depends on the elasticity of migration responses compared with the elasticity of labor supply responses

changes in commuting distances of dutch households this paper is concerned with the analysis of commuting distances the development of commuting distances has become a subject of political concern because of the large flows of traffic involved which are concentrated in a few hours each day and cause considerable congestion problems as well as environmental damage the economic theory of search will be proposed as a theoretical background which motivates the modelling of commuting distance distributions for the empirical analysis a sub sample is used of respondents of the housing demand survey of 1985 approached again in 1988 commuting distances are discussed in relation to household characteristics such as the number of persons the presence of a spouse or partner and her his employment status the apparent rapid increase in commuting distances is due in large part to changes in the employment situation people who change job will often commute over a longer distance after the change occurs changes in housing situation are more or less neutral in th

journals preferences and publishing in agricultural and environmental economics research quality is an increasingly important metric for determining funding allocations promotion and tenure and professional prestige a key metric often used as a proxy for research quality is the ranking of the journal in which a manuscript appears while citation based measures of journal quality are commonly used less is known about other dimensions of journal quality and prestige we report results from an international study using best worst scaling to investigate researchers journal preferences respondents used two criteria to assess journals the impact a paper in the journal would have on career progression and the impact beyond academia of papers in the journal among the sample of journals studied the american journal of agricultural economics is ranked at the top for career progression for the aggregate sample while science was rated at the top for broader impact we find no significant correlation between the journal scores based on the two criteria nor between them and the journals impact factors these results suggest that impact beyond academia is poorly aligned with career incentives and that citation measures reflect poorly if at all peers esteem of journals heteroscedastic scale adjusted latent class models reveal marked heterogeneity in journal preferences related to researchers institutional affiliation and geographic region we find significant differences in error variance over people and choices people were less consistent when choosing their least as opposed to their most preferred journal this finding has broader implications given the burgeoning use of best worst surveys

what s to know about the credibility of empirical economics the scientific credibility of economics is itself a scientific question that can be addressed with both theoretical speculations and empirical data in this review we examine the major parameters that are expected to affect the credibility of empirical economics sample size magnitude of pursued effects number and pre selection of tested relationships flexibility and lack of standardization in designs definitions outcomes and analyses financial and other interests and prejudices and the multiplicity and fragmentation of efforts we summarize and discuss the empirical evidence on the lack of a robust reproducibility culture in economics and business research the prevalence of potential publication and other selective reporting biases and other failures and biases in the market of scientific information overall the credibility of the economics literature is likely to be modest or even low

researcher rank stability across alternative output measurement schemes in the context of a time limited research evaluation the new zealand case abstractthis article focuses on the stability of rankings of academics by research productivity in the context of short term decision making in particular the growing use of national research assessment exercises nrae has increased interest in identifying the contributions of individual researchers to an assessment unit s output and ranking the article concentrates on the assessment of individuals using plausible journal ranking schemes we find that despite statistical evidence of a high degree of stability across journal ranking schemes as indicated by rank correlation coefficients the particular ranking scheme used is of great importance to individual researchers this applies with particular force to academics working within a nrae environment based on individual assessment such as new zealand s pbrf

federal fiscal constitutions risk sharing and redistribution the paper studies the political and economic determinants of regional public transfers specifically it focuses on how such transfers are shaped by alternative fiscal constitutions where a constitution is an allocation of fiscal instruments across different levels of governments plus a procedure for the collective choice of these instruments realistic restrictions on fiscal instruments introduce a tradeoff between risk sharing and redistribution different constitutions produce very different results in particular a federal social insurance scheme chosen by voting provides overinsurance whereas an intergovernmental transfer scheme chosen by bargaining provides underinsurance

a positive model of overlapping income taxation in a federation of states abstract this paper develops a positive theory of overlapping income taxation in a federation of states the analysis provides a complete characterization of the equilibrium federal and states tax rates as functions of the level of total productivity dispersion between the states the federal rate is increasing in the level of total productivity dispersion between the states even if the income of the decisive voter at the federal level is above the mean income given that the individuals income is endogenously determined there exists a negative trade off between the implemented federal tax rate and the resulting states tax rates regardless of the pre tax income of the decisive voter at the state level thus high levels of productivity dispersion between the states cause a higher than optimal federal tax rate together with low states tax rates it is also shown that a system of overlapping income taxation is not efficient the resulting inefficiency might be exacerbated by the implementation of a federal matching grants program contradicting previous results in the related normative literature

an examination of the reliability of prestigious scholarly journals evidence and implications for decision makers in universities all over the world hiring and promotion committees regularly hear the argument this is important work because it is about to appear in prestigious journal x moreover those who allocate levels of research funding such as in the multi billion pound research assessment exercise in uk universities often come under pressure to assess research quality in a mechanical way by using journal prestige ratings this paper s results suggest that such tendencies are dangerous it uses total citations over a quarter of a century as the criterion the paper finds that it is far better to publish the best article in an issue of a medium quality journal like the oxford bulletin of economics and statistics than to publish the worst article or often the worst 4 articles in an issue of a top journal like the american economic review implications are discussed

differences in citation patterns across journal tiers the case of economics we study how citation patterns differ between journal tiers in economics concretely we analyze citations patterns of more than 6 000 economics research articles published in top five second tier and top field economics journals between 1992 and 1996 in line with previous literature we find that top five journals articles generally receive more citations and that the life cycles of those citations are longer however their influence in term of citations is overestimated in its first twenty five years since publication the median top five article accumulates 4 25 around 3 as many citations when compared to the second tier and top field median article we show that this ratio is strongly associated with the field of economics research e g this ratio is the lowest for econometric methods papers and with articles impact e g in all fields of economics research except for theory this ratio decreases sharply as one moves toward high impact articles in term of citations

intra urban workplace and residential mobility under uncertainty abstract the decision of the household to change either its residence or its workplace or both simultaneously is treated as an endogenous decision made in the presence of uncertainty regarding the future characteristics of the new job or residence this decision is analyzed within a model which is explicitly spatial risk aversion is found to have implications for equilibrium location and the decision to move further the costs of risk are qualitatively different from those of transactions costs and changes in commuting costs

the politics of progressive income taxation with incentive effects this paper studies majority voting over quadratic taxation and investigates under which conditions marginal progressivity emerges as a voting outcome in our model with endogenous income there is no majority condorcet winning tax schedule we then investigate less demanding political equilibrium concepts in order to see under which conditions the set of equilibria is composed only of progressive tax functions we follow three strategies i reduction of the policy space to the tax functions that are ideal for some voter ii elimination of weakly dominated strategies and the use of mixed strategies in a standard downsian two party competition game iii assumption that political parties interact repeatedly and care about the size of their majority although each approach captures a different aspect of political behavior they point to the same simulation based conclusion that progressivity is more likely to emerge for most distributions of abilities and that it is actually the only possible voting outcome if the distribution is sufficiently concentrated at the middle

an empirical investigation of intraurban wage gradients abstract intraurban wage gradients have received little attention in the urban literature but have been shown theoretically to be important indicators of the spatial characteristics of urban economic activity this study examines the spatial distribution of wages of five groups of municipal public employees in the chicago smsa negative wage gradients significant at the 0 05 level are found for four of the five labor groups results show that monthly wages decrease on average as much as 24 per additional mile from the city center

labour supply and commuting abstract we examine the effect of commuting distance on workers labour supply patterns distinguishing between weekly labour supply number of workdays per week and daily labour supply we account for endogeneity of distance by using employer induced changes in distance in germany distance has a slight positive effect on daily and weekly labour supply but no effect on the number of workdays the effect of distance on labour supply patterns is stronger for female workers but it is still small

the evolution of the scientific productivity of highly productive economists this paper studies the evolution of research productivity of a sample of economists working in the best 81 departments in the world in 2007 the main novelty is that in so far as a productivity distribution can be identified with an income distribution we measure productivity mobility in a dynamic context using an indicator inspired in an income mobility index suggested by fields 2010 for a two period world productivity is measured in terms of publications weighted by the citation impact of the journals where each article is published in the periodical literature we study the evolution of average productivity productivity inequality the extent of rank reversals and productivity mobility for seven cohorts as well as the population as a whole we offer new evidence confirming previous results about the heterogeneity of the evolution of productivity for top and other researchers however the major result is that contrary to what was expected for our sample of very highly productive scholars the effect of rank reversals between the two periods on overall productivity mobility offsets the effect of an increase in productivity inequality from the first to the second period in the youngest five out of seven cohorts jel a11 a12 b41 d63 i32

job relocation and the racial gap in unemployment in detroit and chicago 1980 to 1990 the spatial mismatch hypothesis argues that residential segregation and job decentralization combine to adversely affect the employment opportunities of minorities while employment is increasingly located outside of central cities residential segregation prevents minorities from moving closer to suburban jobs although this hypothesis has intuitive appeal there is little consensus regarding its empirical validity this study 1 constructs detailed geographic measures of changes in employment opportunities 2 estimates a fixed effects model of changes in the unemployment rate over time and 3 accounts for spatial correlation in the error term neighborhood level employment data from 1980 and 1990 are used to measure changes in the distance to jobs from census tracts in the detroit and chicago metropolitan areas in both cities the decentralization of employment and the loss of manufacturing jobs resulted in substantial changes in the spatial distribution of employment the empirical results indicate that a decline in the spatial proximity to employment is associated with an increase in the unemployment rate for blacks

search theory spatial labor markets and commuting search theory is used to model spatial interactions between residential and employment locations a model for an urbanized region in which employment is concentrated in a number of different centers is developed it is shown that in this model wasteful or excess commuting occurs as a consequence of maximizing behavior of both employers and workers the model is compatible with a spatial equilibrium if informational problems disappear the labor market subdivides into a number of conventional monocentric cities an example concerning an urban area with two employment centers is discussed in detail the model appears to be robust to relaxations of the assumed absence of residential and job mobility

wages and commuting quasi natural experiments evidence from firms that relocate we examine individual level compensating differentials for commuting distance in a quasi natural experiment setting by examining how wages respond to changes in commuting distance induced by firm relocations this set up enables us to test for the relevance of job search frictions within labour market models due to the quasi experimental set up we are able to avoid a range of endogeneity issues we demonstrate that a 1 km increase in commuting distance induces an almost negligible wage increase in the year after the relocation but a more substantial wage increase of about 0 15 three years later 2013 royal economic society

is there value added from the review process in economics preliminary evidence from authors do referees employed by journals merely screen acceptable from unacceptable manuscripts or are they charged with an additional value adding responsibility vis a vis the papers they review drawing from editorial correspondence provided by survey respondents i address this question by examining the relationship between citations of published papers and comments provided by reviewers and editors referees comments demonstrate a positive impact on subsequent citation of papers while comments made by editors show no such impact value adding by editors appears to derive principally from efficient matching of papers with reviewers

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

the substitution between moves and quits if a worker s workplace and residence locations do not maximize utility quits and moves are substitutes a quit or a move alone is more likely than both together records of a single company confirm this simultaneous bivariate probit estimates of move and quit behavior demonstrate that uncontrolled shocks to quits and moves are negatively correlated furthermore when the company relocated from the central business district to a suburb of its metropolitan area the occurrence of either a quit or a move virtually precluded the occurrence of the other among employees whose journeys to work were lengthened by the relocation copyright 1991 by royal economic society

commuting in search of jobs and residences abstract this paper introduces a model which includes residential job moving and commuting behavior when labor and housing markets are characterized by market imperfections imperfect information and moving costs we examine the consequences of these market imperfections on commuting behavior an empirical analysis of commuting behavior indicates that workers commute less if they receive more job offers

an optimal taxation approach to fiscal federalism in a federal system of government each unit of government decides independently how much of each type of public good to provide and what types of taxes and which tax rates to use in funding the public goods in this paper we explore what types of problems can arise from this decentralized form of decision making in particular we describe systematically the types of externalities that one unit of government can create for nonresidents through both its public goods decisions and its taxation decisions the paper also explores briefly what the central government might do to lessen the costs of decentralized decision making

vertical externalities in tax setting evidence from gasoline and cigarettes abstract a common feature of federal systems is that tax bases are joint property consequently state and federal tax setting decisions are interdependent our aim here is to put forward a rudimentary theoretical analysis of this phenomenon and to use the theory as a framework for econometrically estimating the magnitude of the responses we find that when the federal government increases taxes there is a significant positive response of state taxes for example a 10 cent per gallon increase in the federal tax rate on gasoline leads to a 3 2 cent increase in the state tax rate

on the construction of marginal federal personal and social security tax rates in the u s abstract in this article i correct and extend my earlier series on marginal federal personal income tax rates i also construct a measure of the marginal social security tax rate and add this to the income tax rate to obtain a measure of the effective marginal tax rate on income due to federal taxes finally i compare my series on marginal income tax rates and its method of construction with those of barro and sahasakul

tax competition and tax structure in open federal economies evidence from oecd countries with implications for the european union tax competition arguments suggest that governments that operate in an open economy such as local governments should not and will not rely on non benefit taxes such as the income tax yet we observe reliance on income taxes by local governments in many countries and such reliance changes over time evidence from a panel data set of 13 oecd countries over the period 1975 1984 suggests that competition between levels of government resulting in a vertical fiscal externality and between levels of government at the same level resulting in a horizontal fiscal externality provide some economic rationale for these changes moreover the evidence indicates that the vertical and horizontal fiscal externalities interact these results have some interesting implications for fiscal policy in the european union particulary as the eu continues to evolve one implication for the eu is that enlargement that increases tax base disparities within the eu and is not accompanied by an eu level income tax will tend to lower national income tax rates although this must be qualified because it also depends on the mobility of the population a second implication is that fiscal expansion of the eu to include an eu levelincome tax may tend to lower the reliance of national governments on income taxes through the vertical externality but may also tend to equalize tax bases across countries and so increase reliance on national income taxes through the horizontal externality

do academic salaries decline with seniority this article reexamines the negative seniority earnings relationship for academic economists the empirical results show that the anomalous negative seniority effect found in earlier academic market studies holds in the absence of direct measures of research productivity the negative effect however eventually disappears as more comprehensive measures of publishing citations and other productivity measures are included in the wage equation to control for the quantity and quality of faculty productivity faculty with greater seniority appear to be rewarded relatively less simply because many have been relatively less productive than their colleagues with less seniority at similar stages in their careers

citations in economics measurement uses and impacts i describe and compare sources of data on citations in economics and the statistics derived from them constructing data sets of the post publication citation histories of articles published in the top five journals in the 1970s and 2000s i examine distributions and life cycles of citations compare citation histories of articles in different subspecialties in economics and present evidence on the history and heterogeneity of those journals impacts and the marginal citation productivity of additional coauthors i use a new data set of the lifetime citation histories of over 1 000 economists from thirty universities to rank economics departments by various measures and demonstrate the importance of intra and interdepartmental heterogeneity in productivity throughout the discussion summarizes earlier work including the impacts of citations on salaries and nonmonetary rewards and how citations reflect judgments about research quality in economics and the importance of economic ideas
