cost of living inequality during the great recession using detailed barcode level data we construct income group specific price indices for the period of 2004 to 2010 we find substantial differences across income groups arising mainly during the great recession the annual cost of living inflation of the highest quartile has been on average 0 7 percentage points lower than that of the lowest quartile of the income distribution the difference can be explained by the way consumers adjusted their shopping behavior to mitigate the crisis we find that product quality substitution a margin mostly available to richer households is the main mechanism explaining the differences in cost of living inflation our evidence suggests that not accounting for these differences during economic downturns could lead to significant biases in the calculation of inequality and poverty measures jel classifications d12 e31 e32 we thank fernando alvarez erik hurst anil kashyap robert lucas and joseph vavra for their advice and support the paper benefited from comments and suggestions by many others including bong geun choi jorge l garcia jessie handbury sara moreira roberto robatto adriaan ten kate yike wang chen yeh and seminar participants at the university of chicago iea meeting washington university graduate student conference and the midwest macro meeting contacts david argente dargente uchicago edu munseob lee munseob uchicago edu

crime or punishment enforcement of the ncaa football cartel abstract this paper presents theoretical and empirical evidence on the methods that the national collegiate athletic association ncaa and its member schools use to detect violations of its cartel agreement because it is difficult to find direct evidence of cheating we suggest that the volatility of a school s winning percentage is used as a proxy by the ncaa rules has a detect violations empirical evidence also suggests that the enforcement of the ncaa rules has a redistributive effect that benefits consistent winners at the expense of up and coming schools

why do black basketball players work more for less money abstract we explore kahn and sherer s finding that national basketball association players salaries are lower for black than white players in general we do not find evidence that this salary differential is due to the racial preferences of fans specifically we observe that black players actually play more than comparable white players we offer a theory of price discrimination based on relative supplies and supply elasticities in lieu of the racial discrimination argument as an explanation for the black white wage differential

externalities property rights and the allocation of resources in major league baseball most economists who have analyzed professional baseball have concluded that two distinctive features of its labor market the reserve clause and player draft influence the distribution of wealth between players and owners but do not affect the allocation of playing talent among teams such conclusions which are strongly at variance with laymen s views of such matters are derived from theoretical considerations rather than empirical examinations our paper examines data from the two decades of major league history and concludes that on the basis of that data the empirical generalizations of previous economists do not appear to be justified

state level implications of federal tax policies abstract the united states federal fiscal policy has differential impact across states we construct a new quarterly state level dataset that we use to analyze the impact of unexpected changes in federal personal and corporate income taxes we find substantial heterogeneity across states with more than half having no significant response to the tax cuts in addition less capital intensive states have larger responses to corporate tax cuts although puzzling in standard models a model with corporate and non corporate sectors is consistent with this evidence overall our results suggest the importance of variation and reallocation across states in evaluating federal policy

debt deleveraging and the liquidity trap a fisher minsky koo approach in this paper we present a simple new keynesian style model of debt driven slumps that is situations in which an overhang of debt on the part of some agents who are forced into rapid deleveraging is depressing aggregate demand making some agents debt constrained is a surprisingly powerful assumption fisherian debt deflation the possibility of a liquidity trap the paradox of thrift a keynesiantype multiplier and a rationale for expansionary fiscal policy all emerge naturally from the model we argue that this approach sheds considerable light both on current economic difficulties and on historical episodes including japan s lost decade now in its 18th year and the great depression itself

managerial quality team success and individual player performance in major league baseball this paper uses 1969 87 major league baseball data to investigate the impact of managerial quality on team winning and individual player performance managerial quality and player performance are measured as predicted pay based on salary regressions these market based measures permit conclusions about costs and benefits of managerial quality there are two major findings first when player inputs are controlled for higher quality managers lead to higher winning percentages second players tend to play better relative to their prior performance levels the higher the manager s quality these findings suggest that as emphasized by the human resource management literature the quality of management makes an important difference in the performance of organizations

house prices home equity based borrowing and the u s household leverage crisis us household leverage sharply increased in the years preceding the 2007 eco nomic recession the top panel of figure 1 shows the steady rise in household debt since 1975 which accelerated beginning in 2002 in just five years the household sector doubled its debt balance in comparison the contemporaneous increase in corporate debt was modest the middle panel shows that the increase in household debt from 2002 to 2007 translated into a striking rise in household leverage as mea sured by the debt to income ratio during the same time period corporate leverage declined the dramatic absolute and relative rise in us household leverage from 2002 to 2007 is unprecedented compared to the last 25 years one reason for the rapid expansion in household leverage during this period is that mortgage credit became more easily available to new home buyers mian and sufi 2009 strong house price appreciation from 2002 to 2006 however which may have been fueled by the availability of mortgage credit to a riskier set of new home buyers could also have had an important feedback effect on household lever age through existing homeowners given that 65 percent of us households already owned their primary residence before the acceleration in house prices the feedback from house prices to borrowing may be an important source of the rapid rise in household leverage that preceded the economic downturn our central goals in this study are to estimate how homeowner borrowing responded to the increase in house prices and to identify which homeowners responded most aggressively we examine this home equity based borrowing channel using a dataset consisting of anonymous individual credit files of a national consumer credit bureau agency we follow a random sample of over 74 000 us homeowners who owned their homes as of 1997 at an annual frequency from the end of 1997 until the end of 2008 the bottom panel of figure 1 plots the growth in debt of 1997 homeowners over time and shows that existing homeowners borrow significantly more debt as their house prices appreciate from 2002 to 2006 while the aggregate trend is suggestive

measuring managerial efficiency the case of baseball in economic analysis the role of the entrepreneur is paramount to the production process the entrepreneur is engaged in a darwinian game of efficiently transforming scarce resource inputs into outputs in the modern business organization this role is delegated to managers despite the conceptual importance of the role of management in the production function very little is known about the actual effect on output of variations in managerial skill in part this is due to the lack of proprietory data in part it is due to difficulties in measuring the outputs and inputs of complex production processes in a meaningful way a number of investigators have employed the concept of the frontier production function as developed by forsund and hjalmarsson 1 and timmer 6 and more recently by schmidt and lovell 3 to measure the effect on technical and price efficiency of various property rights structures or institutional constraints to our knowledge estimates of managerial efficiency have not been obtained with firm specific data except for some regulated industries in this study we estimate managerial efficiency by manager and by firm managerial marginal revenue product the rate of change in managerial efficiency over years of experience and relative factor price efficiency we use major league baseball teams over the period 1961 1980 as our data source what is particularly appealing about the choice of major league baseball teams as the industry for analysis is that outputs win percent and inputs player skills are unambiguously measured and the production function is simply specified as shown by scully 5 our results indicate that managerial skill in baseball contributes very substantially to the production process the paper will evolve as follows first the concept of the frontier production function is briefly outlined then estimates of managerial efficiency by manager and by team are provided and discussed a managerial efficiency learning curve is estimated an estimate of managerial marginal revenue product provided and the managerial efficiency

optimal monetary policy in a currency area abstract this paper investigates how monetary policy should be conducted in a two region general equilibrium model with monopolistic competition and price stickiness this framework delivers a simple welfare criterion based on the utility of the consumers that can be used to evaluate monetary policy in a currency area if the two regions share the same degree of nominal rigidity the terms of trade are completely insulated from monetary policy and the optimal outcome is obtained by targeting a weighted average of the regional inflation rates these weights coincide with the economic sizes of the region if the degrees of rigidity are different the optimal plan implies a high degree of inertia in the inflation rate but an inflation targeting policy in which higher weight is given to the inflation in the region with higher degree of nominal rigidity is nearly optimal

how does credit supply expansion affect the real economy the productive capacity and household demand channels credit supply expansion can affect an economy by increasing productive capacity or by boosting household demand in this study we develop a test to determine if the household demand channel is present and we implement the test using both a natural experiment in the united states in the 1980s and an international panel of 56 countries over the last several decades consistent with the importance of the household demand channel we find that credit supply expansion boosts nontradable sector employment and the price of nontradable goods with limited effects on tradable sector employment such credit expansions amplify the business cycle and lead to more severe recessions

are micro and macro labor supply elasticities consistent a review of evidence on the intensive and extensive margins we evaluate whether state of the art macro models featuring indivisible labor are consistent with modern quasi experimental micro evidence by synthesizing evidence on both the intensive and extensive margins we find that micro estimates are consistent with macro estimates of the steady state hicksian elasticities relevant for cross country comparisons on both the extensive and intensive margins however micro estimates of intertemporal substitution frisch elasticities are an order of magnitude smaller than the values needed to explain business cycle fluctuations in aggregate hours by preferences the key puzzle to be resolved is why micro and macro estimates of the frisch extensive margin elasticity are so different

regional heterogeneity and the refinancing channel of monetary policy we argue that the time varying regional distribution of housing equity influences the aggregate consequences of monetary policy through its effects on mortgage refinancing using detailed loan level data we show that regional differences in housing equity affect refinancing and spending responses to interest rate cuts but these effects vary over time with changes in the regional distribution of house price growth we build a heterogeneous household model of refinancing with mortgage borrowers and lenders and use it to explore the monetary policy implications arising from our regional evidence we find that the 2008 equity distribution made spending in depressed regions less responsive to interest rate cuts thus dampening aggregate stimulus and increasing regional consumption inequality whereas the opposite occurred in some earlier recessions taken together our results strongly suggest that monetary policy makers should track the regional distribution of equity over time

life cycle prices and production we use scanner data and time diaries to document how households substitute time for money through shopping and home production we document substantial heterogeneity in prices paid for identical goods for the same area and time with older households shopping the most and paying the lowest prices doubling shopping frequency lowers a good s price by 7 to 10 percent we estimate the shopper s price of time and use this series to estimate an elasticity of substitution between time and goods in home production of roughly 1 8 the observed life cycle time allocation implies a consumption series that differs markedly from expenditures

racial integration as an innovation empirical evidence from sports leagues this paper treats racial integration as an innovation in economic process in which economic entities find it advantageous to utilize potentially more productive inputs previously unavailable due to law custom or managerial discretion data on the racial integration of major league baseball and atlantic coast conference basketball are employed to address this issue the central question examined is which type of team integrated first losers or winners the results strongly support the idea that entrepreneurship trumps competitive rivalry that is winning teams led the process of racial integration jel li j7 one of the watershed events in u s history is the struggle to achieve a racially integrated society while the civil rights laws and court rulings in the 195o s 196o s and 197o s are among the major changes in public policy that gradually led to a breakdown of jim crow rule in the american south other changes in law and custom also motivated the process of racial integration across time and place indeed segregation was not limited to the south but was a prominent feature of many national organizations and markets despite the extensive commentary on these events from various perspectives there has been very little economic analysis of the actual process of racial integration economists have focused their efforts on the economics of discriminatio n while the actual process by which individuals firms and

the elasticity of substitution between time and market goods evidence from the great recession the elasticity of substitution between time and market goods we document a change in household shopping behavior during the great recession households purchased more on sale larger sizes and generic products increased coupon usage and shopping at discount stores we estimate that the returns to these shopping activities declined during the recession and therefore this behavior implies a significant decrease in households opportunity cost of time using the estimated cost of time and time use data we estimate a high elasticity of substitution between market expenditure and time spent on non market work we find that households smooth a sizable fraction of consumption by varying their time allocation during recessions institutional subscribers to the nber working paper series and residents of developing countries may download this paper without additional charge at www nber org

the aggregate implications of regional business cycles during the last recession and its aftermath aggregate price growth and aggregate nominal wage growth remained robust despite the high rate of unemployment we document that u s states with weaker labor markets experienced lower price growth lower nominal wage growth and lower real wage growth during the great recession given that reliable measures of local prices do not exist we create our own state price indices using scanner data from the nielsen retail scanner database the main innovation of the paper is the development of an econometric procedure that combines cross region data with aggregate time series data to infer the underlying shocks driving both aggregate and regional business cycles applying our procedure to the great recession we find that a combination of both demand and supply shocks are necessary to account for the joint dynamics of aggregate prices wages and employment during the 2007 2012 period in contrast we find that only demand shocks are needed to explain the cross region variation the results suggest that only using cross region variation to explain aggregate fluctuations is insufficient when shocks do not have a substantive regional component

regional effects of exchange rate fluctuations we exploit differences across u s states exposure to trade to study the effects of changes in the exchange rate on economic activity across states trade weighted exchange rate depreciations are associated with increased state exports reduced state unemployment and higher state hours worked the effects are particularly strong during periods of economic slack a multiregion model with interstate trade and labor flows calibrated to match state level trade data and migration flows replicates the empirical relationship between exchange rates and unemployment the high degree of interstate trade plays an important role in transmitting shocks across states in the first year whereas interstate migration shapes cross sectional patterns in later years we use the model to study the regional effects of tariffs in the united states the model suggests that a 25 chinese import tariff on u s goods would be felt throughout the united states even in states with small direct linkages to china raising unemployment rates by 0 2 to 0 7 percentage points in the short run

do employers pay for consistent performance evidence from the nba i introduction there are many economic models of labor contracting that feature job performance monitoring by employers when there is asymmetric information about worker behavior these models focus on a variety of agency issues and generate implications about contract terms such as initial wages wage tenure profiles termination rates and involuntary unemployment 1 it is typically assumed in these models that a worker s marginal revenue product mrp is known at the time of hiring but that costly monitoring is necessary to enforce contractual terms this paper deals with another issue suppose there is no agency problem but both worker and firm are equally uninformed about mrp when contracts are signed and work begins how are initial wages and other contractual terms influenced by symmetric uncertainty about mrp contracts are often formulated on the basis of various provisional predictors of mrp such as grades in college letters of reference from teachers and former employers work experience and performance test scores typically employers expend resources to acquire such information at hiring and continue to engage in costly performance evaluation afterward under such conditions the purpose of monitoring is discovery not contract enforcement information acquired from on the job monitoring is used to make decisions about adjustment of contractual terms job assignment and retention for example tenure track college professors are often evaluated yearly and must submit information about various aspects of on the job performance such as student evaluations of teaching research papers completed committee assignments etc on the job monitoring of workers is costly and is likely to affect the worker s pay in fact a worker may agree to pay for his monitoring if the information revealed by monitoring has alternative uses elsewhere in the labor market in this paper we develop and test a model of a firm facing costly on the job monitoring when there is symmetric information and we develop a number of novel implications for initial salaries the central feature of our model is that monitoring can be costly when a worker s performance over time is variable notably the model predicts that there will be an unambiguous inverse relationship between variance of mrp and initial wages we obtain this and other predictions without resorting to assumptions about employers and employees utility functions that risk aversion models require we regard our explanation of the relationship between variance and wages to be theoretically more robust than what the risk aversion literature would predict because that literature predicts an ambiguous relationship for example stiglitz 1974 232 uses a risk aversion model to demonstrate that wages and risk are inversely related only under very restricted conditions specifically if the worker is more risk averse than the firm and if labor s elasticity of output does not exceed some threshold level in contrast our prediction is based on an information transactions costs model with no restricted conditions we build upon earlier work by bodvarsson 1987 1989 who created a salary determination model in which a worker s output is variable over time bodvarsson characterized on the job monitoring as a sequential sampling experiment where the employer periodically samples from the worker s mrp distribution and stops when she believes there is enough information to determine the true underlying mrp a key implication of bodvarsson s model is that expected monitoring costs are higher for workers with variable output and therefore if workers pay all or part of the cost of monitoring salaries of such workers will be lower in his earlier paper this proposition was tested using a share contracting model and data on commercial fishing in the later paper a fixed wage model with educational signaling was developed but never tested we extend bodvarsson s fixed wage model and test it on an occupation that has many characteristics described by our model professional basketball players in the national basketball association nba

shirking on the court testing for the incentive effects of guaranteed pay prior work on long term contracts and the incentive to shirk has focused almost exclusively on major league baseball the current inquiry is the first to examine shirking in the national basketball association we employed two different measures of player productivity when the nba s measure is used we find evidence consistent with allegations of shirking behavior but when productivity is measured in a fashion more consistent with economists definition of marginal product the evidence of shirking evaporates jel j41 j44 l83 i introduction

inequality among equals embedding market and authority in league sports in league sports the regulatory authority of leagues is thought to counter market pressures that would otherwise concentrate player talent in smsas with the largest market potential the presumed opposition between authority and markets is not supported by league histories in the four major team sports these histories show that contrary to expectations market potential has the greatest influence on winning when league authority is formally strongest market potential has no influence on performance when league authority is opposed by antitrust law player unions rival leagues or league members to explain this anomaly authority and market relations must both be seen as embedded within the multiplex relations among team owners these relations changed dramatically with the rise of national audiences in the past three decades inequality among equals replaced inequality among unequals as the support of a rootless national audience replaced rooted and unequal local audiences altering the opportunity

convergence clustering and their effects on attendance in the japan professional baseball league in this research using a panel data set for the japan professional baseball league jpbl during the post wwii period we apply the technique developed by hobijn and franses 2000 to examine the competitive balance from the view point of convergence and its effect upon game attendance the jpbl comprises two leagues the central league cl and the pacific league pl the cl is far more popular with fans than the pl our estimation results showed that the number of the pl clusters continues to go towards unity thereby raising the uncertainty of the outcome to increase the pl game attendance more rapidly also attendance by cl fans tends to be more inelastic with team performance than for the pl therefore the pl payroll was more elastic to wins than that of the cl the features of each league have crucial impacts on the outcomes and the behaviours of team insiders such as players and managers

the cyclicality of sales regular and effective prices business cycle and policy implications author s coibion olivier gorodnichenko yuriy hong gee hee abstract we study the cyclical properties of sales regular price changes and average prices paid by consumers effective prices using data on prices and quantities sold for numerous retailers across many us metropolitan areas inflation in the effective prices paid by consumers declines significantly with higher unemployment while little change occurs in the inflation rate of prices posted by retailers this difference reflects the reallocation of household expenditures across retailers a feature of the data which we document and quantify rather than sales we propose a simple model with household store switching and assess its implications for business cycles and policymakers jel d12 e31 e32 l25 l81

income and wealth heterogeneity in the macroeconomy how do movements in the distribution of income and wealth affect the macroeconomy we analyze this question using a calibrated version of the stochastic growth model with partially uninsurable idiosyncratic risk and movements in aggregate productivity our main finding is that in the stationary stochastic equilibrium the behavior of the macroeconomic aggregates can be almost perfectly described using only the mean of the wealth distribution this result is robust to substantial changes in both parameter values and model specification our benchmark model whose only difference from the representative agent framework is the existence of uninsurable idiosyncratic risk displays far less cross sectional dispersion and skewness in wealth than u s data however an extension that relies on a small amount of heterogeneity in thrift does succeed in replicating the key features of the wealth data furthermore this extension features aggregate time series that depart significantly from permanent income behavior

structural adjustment and soil degradation in tanzania a cge model approach with endogenous soil productivity abstract in this paper a model of the nitrogen cycle in the soil is incorporated in a computable general equilibrium cge model of the tanzanian economy thus establishing a two way link between the environment and the economy for a given level of natural soil productivity profit maximising farmers choose input levels and hence production volumes which in turn influence soil productivity in the following years through the recycling of nitrogen from the residues of roots and stover and the degree of erosion the model is used to simulate the effects of typical structural adjustment policies like a reduction in agro chemicals subsidies reduced implicit export tax rate etc after 10 years the result of a joint implementation is a 9 higher gross domestic product gdp level compared to the baseline scenario the effect of soil degradation is found to represent a reduction in the gdp level of more than 5 for the same time period

the fable of the bees an economic investigation ever since a c pigou wrote his books on welfare a divergence between private and social costs has provided the main argument for instituting government action to correct allegedly inefficient market activities the analysis in such cases has been designed less to aid our understanding of how the economic system operates than to find flaws in it to justify policy recommendations both to illustrate the argument and to demonstrate the nature of the actual situation the quest has been for real world examples of such defects

coarse pricing policies the muted volatility of inflation during the great recession and its aftermath has refocused attention on the constraints that firms face when adjusting prices using new empirical and theoretical results i argue that each firm s choice of how much information to acquire to set prices plays a central role in determining the patterns of pricing at the product level and the degree of aggregate price rigidity in response to shocks in support of the information channel i present product level evidence that firms price goods using coarse pricing policies that are updated infrequently and consist of a small menu of prices firms are heterogeneous in the complexity and duration of their pricing policies and this heterogeneity is reflected in differential responses to the great recession cycle with firms exhibiting more complex policies responding more aggressively i develop a theory of information constrained price setting that generates coarse pricing endogenously and quantitatively matches the discreteness duration and volatility of policies in the data the information friction dampens the responsiveness of prices to shocks and coupled with heightened volatility induces firms to keep prices relatively high to protect against losses in an uncertain environment

shift share designs theory and inference we study inference in shift share regression designs such as when a regional outcome is regressed on a weighted average of sectoral shocks using regional sector shares as weights we conduct a placebo exercise in which we estimate the effect of a shift share regressor constructed with randomly generated sectoral shocks on actual labor market outcomes across u s commuting zones tests based on commonly used standard errors with 5 nominal significance level reject the null of no effect in up to 55 of the placebo samples we use a stylized economic model to show that this overrejection problem arises because regression residuals are correlated across regions with similar sectoral shares independent of their geographic location we derive novel inference methods that are valid under arbitrary cross regional correlation in the regression residuals we show using popular applications of shift share designs that our methods may lead to substantially wider confidence intervals in practice

on the evolution of competitive balance the impact of an increasing global search the coase theorem maintains that where free market precepts exist the allocation of property rights does not impact the distribution of resources an application to major league baseball suggests that institutions such as free agency and the reverse order amateur draft would not impact player distributions and therefore would not impact competitive balance the present study finds that the distribution of wins is generally consistent with the precepts of the coase theorem and therefore suggests a course for those who wish to alter the level of competitive balance major league baseball should increase its focus on expanding the size of its labor pool jel o15 l83 c22

monetary non neutrality in a multisector menu cost model empirical evidence suggests that as much as one third of the u s business cycle is due to nominal shocks we calibrate a multisector menu cost model using new evidence on the cross sectional distribution of the frequency and size of price changes in the u s economy we augment the model to incorporate intermediate inputs we show that the introduction of heterogeneity in the frequency of price change triples the degree of monetary non neutrality generated by the model we furthermore show that the introduction of intermediate inputs raises the degree of monetary non neutrality by another factor of three without adversely affecting the model s ability to match the large average size of price changes a single sector model with a frequency of price change equal to the median rather than the mean generates monetary non neutrality similar to that in our multisector model our multisector model with intermediate inputs generates variation in real output in response to calibrated aggregate nominal shocks that can account for roughly 23 of the u s business cycle

uniform pricing in us retail chains we show that most u s food drugstore and mass merchandise chains charge nearly uniform prices across stores despite wide variation in consumer demographics and competition demand estimates reveal substantial within chain variation in price elasticities and suggest that the median chain sacrifices 16 million of annual profit relative to a benchmark of optimal prices in contrast differences in average prices between chains are broadly consistent with the optimal benchmark we discuss a range of explanations for nearly uniform pricing highlighting managerial inertia and brand image concerns as mechanisms frequently mentioned by industry participants relative to our optimal benchmark uniform pricing may significantly increase the prices paid by poorer households relative to the rich dampen the response of prices to local economic shocks alter the analysis of mergers in antitrust and shift the incidence of intranational trade costs

team effects on compensation an application to salary determination in the national hockey league leo h kahane studies of salary determination largely model pay as a function of the attributes of the individual and the workplace i e employer size job characteristics and so forth this article empirically investigates an additional factor that may influence individual pay specifically coworker productivity data from professional sports are used to evaluate this question because both salary and teammate performance measures are readily available we find that team attributes have both direct effects on an individual s pay and indirect effects through altering the rates at which individual player productive characteristics are valued jel j31 l83 i introduction when complementary exists between labor inputs individual productivity may be poorly measured by treating the individual worker separately from the character of the organization or team within which he works namely individual productivity may vary when working in different settings to the extent that coworkers offer different degrees of assistance 1 if such complementary between human capital inputs is present say a team dynamic it suggests the possible existence of both team and individual effects on productivity and hence compensation empirical analysis of team effects has been hindered by the lack of data on individuals and their coworkers including managers one source though that contains much of this requisite information is data on professional sports teams in this article we exploit this unique attribute of professional sports data in order to empirically assess the effect of complementarities between labor inputs on individual compensation specifically we use a team sport setting to situate the worker in an organizational environment where we can observe the impact of coworkers on individual productivity thereby allowing us to examine the separate effects of individual and team productivity on salary determination the general question asked is whether individual attributes are valued or rewarded differently in different work environments or in our specific case on different teams this study will investigate these questions by empirically assessing the effects of coworker productivity that is the effects of the qual ity productivity of teammates on individual compensation although a number of different highly team oriented sports would serve our purpose such as basketball this particular study uses data from professional hockey to investigate team effects on compensation 2 the remainder of the article is organized as follows section ii outlines the empirical framework used to analyze the posited team effects and discusses some of the theoretical issues relating to team effects on compensation section iii describes the data used in the analysis section iv reports the empirical results and section v reports our conclusions and directions for further work ii team and coworker effects as noted above the goal of this study is to evaluate empirically whether average coworker attributes 1 affect individual salaries 2 affect the rate at which individual attributes are valued by the firm and 3 are complementary inputs to the attributes of individual team members the question arises though as to why we might expect on theoretical grounds that individual players would earn any part of the team s contribution the classic model of alchian and demsetz 1972 suggests that the capitalist manager will reap the returns from any incremental team output as the primary function of the manager is to discover complementarities between inputs and enhance organizational output by optimally combining resources and to monitor effort so as to reduce shirking as a result the manager will capture all of the returns that are not specific to the inputs in which case we would not expect to observe team effects on individual compensation yet although a manager acting as the residual claimant is one solution to the problem of reducing shirking in the context of complementary inputs whose effort is difficult to monitor other models suggest that it may be desirable to compensate team members based on the value of team output in order to provide optimal incentives for effort for example see akerlof 1982

the role of prices in measuring the poor s living standards in this paper we revisit two pieces of conventional wisdom in the current debate about poverty paying close attention to the price data underlying these findings that the poor pay more than households of higher income for the goods and services they purchase and that poverty rates at least as measured by the u s census have remained essentially flat since the late 1960s raising questions about the success of the policies implemented to reduce poverty by examining scanner data on thousands of household purchases we find that the poor pay less not more for the goods they purchase and by extending the advances on price measurement in the recent decade back to the 1970s we find that current poverty rates are less than half of the official numbers

the cost of soil erosion in nicaragua the cost of soil erosion is not so much dependent on the physical amount of soil lost as determined by the economic effects of these losses soil erosion has both onsite and offsite effects loss of soil productivity is the main onsite effect while enhanced productivity of downstream land sedimentation and eutrophication of waterways and reservoirs are common offsite effects in this paper we consider only the onsite effects of erosion the loss of agricultural productivity is however studied within a broader economic framework than usual by incorporating the direct economic effects of soil loss into a general equilibrium model it is possible to shed light on some of the many interlinkages between agricultural activity and other parts of the economy which are important for determining the social cost of soil erosion based on model simulations we find that soil erosion represents a considerable drag on the nicaraguan economy but that the burden of soil erosion depends on conditions and policies in non agricultural markets such as the labour market furthermore the sharing of the burden is not always to the disadvantage of the peasants while uncertainties in data and modelling prevent us from drawing strong conclusions the present study underlines the importance of considering the overall economic environment when policy proposals for mitigating excessive soil erosion is formulated

coaching team production coaching team production the actual function of managers is the subject of much debate using data on more than 3000 male college basketball players their coaches and their skill levels we find a positive and significant relation between our ability to replicate an individual coach s allocation of playing time across players and his winning percentage although this result does not answer the central question of just what it is that managers contribute the results do support the property rights paradigm managers are the employees of workers and more generally sports data can be used to help understand related economic processes where quantifiable measures of inputs and outputs are more costly to obtain what is meant by performance input energy initiative work attitude perspiration rate of exhaustion or output sometimes by inspecting a team member s input activity we can better judge his output effect it is not always the case that watching input activity is the only or best means of detecting measuring or monitoring output effects of each team member but in some cases it is a useful way i introduction a major tenet of the alchian demsetz 1972 representation of the firm is that managers are hired by workers to prevent shirking and malfeasance in their own ranks absent overseers individual workers bear only a fraction of the cost of shirking and hence everyone undersupplies labor relative to its opportunity cost in this world the managerial function is to monitor inputs and meter rewards thereby reducing the incentive to shirk and raising each worker s marginal productivity the more dependence there is in the marginal products of laborers the more important the role of management this view of supervision is simultaneously intuitively pleasing and difficult to quantify this paper investigates the role of management in a setting where indisputably there is team production intercollegiate basketball 1 data on 3012 college basketball players across ten years and sixty five teams are used to replicate one aspect of coaching the allocation of playing time next we attempt to link coaching decisions to winning the goal is to determine if coaches who manage well by our standards are successful section ii motivates the paper in section iii the empirical methodology is detailed the monitoring function is estimated and related to coaching success section iv contains a summary and conclusion ii coaching decisions the essence of team production is interdependence and the inherent immeasurability of marginal productivity across workers however this does not mean that proxies for marginal productivity cannot be developed managers monitor worker inputs and deduce marginal products accordingly of course some inputs are more cheaply quantified than others attitude is hard to measure but heart rate is easy sweat is observed cheaply but workers can feign exhaustion in the famous chinese boatpullers fable the coxswain uses his whip to insure that coolies pull efficiently to persuade each worker to give the appropriate effort 2 mcmanus 1975 341 relates a story told by cheung boats are pulled upstream by a team of coolies prodded by an overseer with a whip an american lady horrified at the sight of the overseer whipping the men as they strained at their harness demanded that something be done about the brutality she was quickly informed those men own the rights to draw boats over this stretch of water and they have hired the overseer and given him his duties here the monitor uses his vision intuition and experience to determine shirking counseling the loafers with his whip but employing subjective observation is just one way to monitor

priors from general equilibrium models for vars abstract this paper uses a simple new keynesian dynamic stochastic general equilibrium model as a prior for a vector autoregression shows that the resulting model is competitive with standard benchmarks in terms of forecasting and can be used for policy analysis jel classification c11 c32 c53 key words bayesian analysis dsge models forecasting vector autoregressions 1 introduction dynamic stochastic general equilibrium dsge models are popular nowadays in macroeconomics they are taught in virtually every economics ph d program and represent a predominant share of publications in the field yet when it comes to policy making these models are scarcely used at least from a quantitative point of view the main quantitative workhorse for policy making at the federal reserve system is frb us a macro econometric model built in the cowles foundation tradition a style of macroeconomics that is no longer taught in many ph d programs 1 in their decision process fed policy makers rely heavily on forecasting they want to know the expected path of inflation in the next few quarters and by how much a 50 basis point increase in the federal funds rate would affect that path frb us offers answers to these questions answers that many macroeconomists would regard with suspicion given both the lucas 1976 critique and the fact that in general the restrictions imposed by cowles foundation models are at odds with dynamic general equilibrium macroeconomics sims 1980 general equilibrium models on the other hand have a hard time providing alternative answers the fact that these models are perceived to do badly in terms of forecasting as they are scarcely parameterized is perhaps one of the reasons why they are not at the forefront of policy making while progress is being made in the development of dsge models that deliver acceptable forecasts e g smets and wouters 2003 this paper proposes an approach that combines a stylized general equilibrium model with a vector autoregression var to obtain a specification that both forecasts well and is usable for policy analysis specifically the approach involves using prior information coming from a dsge model in the estimation of a vector autoregression loosely speaking this prior can be thought of as the result of the following exercise i simulate time series data from the dsge model ii fit a var to these data in practice we replace the sample moments of the simulated data by population moments computed from the dsge model solution since the dsge model depends on unknown structural parameters we use a hierarchical prior in our analysis by placing a distribution on the dsge model parameters a tightness parameter controls the weight of the dsge model prior relative to the weight of the actual sample markov chain monte carlo methods are used to generate draws from the joint posterior distribution of the var and dsge model parameters the paper shows that the approach makes even a fairly stylized new keynesian dsge model competitive with standard benchmarks in terms of forecasting real output growth inflation and the nominal interest rate the three variables that are of most interest to policy makers 2 up to this point our procedure borrows from the work of dejong ingram and whiteman 1993 and ingram and whiteman 1994 who are the first to use priors from dsge models for vars ingram and whiteman showed that prior information from the bare bones stochastic growth model of king plosser and rebelo 1988 is helpful in forecasting real economic activity such as output consumption investment and hours worked in addition to documenting the forecasting performance of a trivariate var with a prior derived from a monetary dsge model this paper makes two contributions that significantly extend the earlier work first we show formally how posterior inference for the var parameters can be translated into posterior inference for dsge model parameters

hartwick s rule in open economies to sustain constant consumption the hartwick rule prescribes reinvesting all resource rents in reproducible capital this paper shows that the rule does not apply to open economies since the underlying stationary technology assumption is violated when gains from trade are taken into account a correct analog to the hartwick rule for open economies is developed and applied to a model of capital accumulation and resource depletion la regle de hartwick dans les e conomies ouvertes pour maintenir la consommation constante la regle de hartwick prescrit qu il faut reinvestir toutes les rentes des ressources dans du capital reproductible ce me moire montre que la regle ne s applique pas dans le cas d economies ouvertes parce que le postulat d une technologie stationnaire n9est pas satisfait quand on tient compte des gains engendres par le commerce international l auteur developpe une version correcte pour les economies ouvertes dans 1 esprit de la regle de hartwick et l applique a un modele d accumulation de capital et d epuisement des ressources

rule changes and competitive balance in japanese professional baseball i introduction since rottenberg s 1956 classic analysis of baseball s reserve clause economists have been interested in whether the rules for initially allocating players among major league baseball mlb teams affect their final allocation el hodiri and quirk 1971 formalized rottenberg s analysis of player allocation rules for a sports league in which each team independently maximizes its profits within the league s institutional constraints 1 consider the effect of a player draft regime and an open bidding regime on the allocation of new players often called rookies if a player draft allows team a to claim initially a particular new player and that player would generate a higher marginal product with team b then the two teams have incentives to make an exchange and send the player to team b alternatively under an open bidding regime the new player signs with the team presenting the highest offer i e team b with which he generates the highest marginal product assuming that transaction costs of exchanging players are zero el hodiri and quirk showed that the final allocation of players across teams will be the same in both regimes this result that the final allocation of players does not depend on the rules governing the initial allocation of players is baseball s version of the coase theorem following coase s 1960 analysis this invariance result vanishes if there are obstacles to exchanging players after the initial allocation in an open bidding regime players are initially allocated to the team with which they have the highest marginal product thereby eliminating the need for player exchanges since the best players are likely to generate the highest marginal product with teams in cities that have a high demand for winning games in an open bidding regime these teams are likely to have higher winning percentages and win more championships than other teams 2 by contrast in a draft regime the best players are often initially allocated to a team located in a city with a low demand for winning games if there are obstacles to player exchange then players will be allocated more evenly across teams under a draft regime and competitive balance should improve both within a given season and over time 3 empirical studies have used performance data from north american mlb to analyze whether changes in the rules for allocating rookies among teams affect competitive balance fort and quirk s 1995 recent study found that mlb s change in 1965 from an open bidding to a draft regime for allocating new players increased competitive balance in the american league and had little effect on competitive balance in the national league the power of statistical tests conducted with the mlb data is however severely limited due to the small number of observations from the draft regime period this article uses a larger data set from japanese baseball to examine the same rule change that economists have analyzed for mlb remarkable as it may seem the japanese professional baseball league jpbl adopted the same rule change from an open bidding to a draft regime for rookies in the same year 1965 as major league baseball our goal is to examine how the rule change in the jpbl affected competitive balance in its two leagues and to compare the outcomes of these two remarkably similar experiments set in two very different cultures ii studies of north american mlb and japanese jpbl daly and moore 1981 compared player allocation in the two regimes for allocating rookies by examining mlb s 1965 switch from an open bidding to a draft regime they used pre and post 1965 performance data from the american and national leagues to examine several measures of competitive balance in the post 1965 draft regime they found substantially more competitive balance in the american league and somewhat more competitive balance in the national league using different tests for competitive balance fort and quirk 1995 1 282 86 also found evidence for more competitive balance in the american league but found no change in competitive balance in the national league

free agency competitive balance and diminishing returns to pennant contention e woodrow eckard this article argues that the 1976 introduction of free agency increased competitive balance in major league baseball the evidence is based on a new empirical measure that captures the key dynamic element of balance year to year fluctuations in team performance my hypothesis is that diminishing returns to each additional year s production of a pennant contending team reduces the incentive to bid continually for top players free agency allows talent to be reallocated more readily to potential new contenders given that player sales had been restricted prior to 1976 the hypothesis is supported by evidence of declining attendance during contending streaks jel l83 i introduction since the inception of free agency in major league baseball mlb over 20 years ago its effect on competitive balance has been controversial for almost a century the reserve system had assigned de facto property rights in players services to mlb teams this changed after 1976 when veteran players were allowed to unilaterally sell their services to the highest bidder team owners predicted a consequent decline in competitive balance arguing that large market clubs would outbid others for talent and come to dominate this claim is still made today as the basis for major restructuring proposals such as new restrictions on player salaries and mobility team payroll caps and various cross subsidization schemes 1 economists have examined the issue from both theoretical and empirical angles theorists such as el hodiri and quirk 1971 implicitly agree with the owners that the best players concentrate where their marginal revenue products mrps are the highest that is in high demand cities that also may be the most populous debate has revolved instead around rottenberg s 1956 invariance proposition which states that the distribution of playing talent will be the same under both systems if player sales are unrestricted teams where mrps are the highest purchase the services of the best players whether from other low mrp clubs or directly from the players themselves free agency therefore should not affect competitive balance critics such as daly 1992 argue that before 1976 first line players seldom were sold so the invariance proposition does not apply several studies examine empirically the effect of free agency on competitive balance taken together the results are consistent with the invariance proposition namely balance did not change this article argues that these studies use balance measures that ignore a critical aspect of competition namely year to year changes in a team s position in league standings using empirical measures that capture this dynamic i report new evidence that balance improved after free agency i then extend the existing theory of sports leagues to explain why free agency might cause such an outcome and provide an independent test of the theory specifically there are diminishing marginal returns to each additional year s production of a pennant contending team reducing the incentive to bid continually for top players this allows also rans to obtain the talent necessary to improve their performance and become contenders i also provide evidence that quality players were seldom sold under the old reserve system ren dering the invariance proposition moot the article is organized as follows the next section reviews the relevant theoretical and empirical literature section iii describes my measures of competitive balance and section iv presents empirical results comparing balance in mlb before and after free agency section v provides evidence that sales of first line players were sufficiently rare as to nullify the invariance proposition section vi presents the theoretical argument linking free agency to an improvement in balance followed by a supporting empirical test in section vii section viii summarizes and concludes the article

inflation dynamics and time varying volatility new evidence and an ss interpretation is monetary policy less effective at increasing real output during periods of high volatility than during normal times in this article i argue that greater volatility leads to an increase in aggregate price flexibility so that nominal stimulus mostly generates inflation rather than output growth to do this i construct price setting models with volatility shocks and show these models match new facts in cpi micro data that standard price setting models miss i then show that these models imply that output responds less to nominal stimulus during times of high volatility furthermore because volatility is countercyclical this implies that nominal stimulus has smaller real effects during downturns for example the estimated output response to additional nominal stimulus in september 1995 a time of low volatility is 55 larger than the response in october 2001 a time of high volatility jel codes e10 e30 e31 e50 d8 copyright 2014 oxford university press
