a multiplicative model of optimal ceo incentives in market equilibrium this paper presents a unified theory of both the level and sensitivity of pay in competitive market equilibrium by embedding a moral hazard problem into a talent assignment model by considering multiplicative specifications for the ceo s utility and production functions we generate a number of different results from traditional additive models first both the ceo s low fractional ownership the jensen murphy incentives measure and its negative relationship with firm size can be quantitatively reconciled with optimal contracting and thus need not reflect rent extraction second the dollar change in wealth for a percentage change in firm value divided by annual pay is independent of firm size and therefore a desirable empirical measure of incentives third incentive pay is effective at solving agency problems with multiplicative impacts on firm value such as strategy choice however additive issues such as perk consumption are best addressed through direct monitoring jel d2 d3 g34 j3

competition regimes and air transport costs the effects of open skies agreements the relevance of transport costs has increased as liberalization continues to reduce artificial barriers to trade is it worthwhile to implement policies designed to increase competition in transport markets focusing on air transport this paper quantifies the effects of liberalization of air cargo markets on transport costs between 1990 and 2003 the united states implemented a series of open skies agreements providing a unique opportunity to assess the effect that a change in the competition regime has on prices in our sample open skies agreements reduce air transport costs by 9 and increase by 7 the share of imports arriving by air those results hold for developed and upper middle income developing countries but for lower middle income and low income developing countries open skies agreements do not reduce air transport costs d 2005 elsevier b v all rights reserved

theory based measurement of the saving investment correlation with an application to norway i introduction the findings of feldstein and horioka 19c 0 have led to numerous theoretical and empirical papers on the close correlation between domestic saving and domestic investment and its supposed implications for international capital mobility feldstein and horioka 1980 317 state that with perfect world capital mobility there should be no relation between domestic saving and domestic investment saving in each country responds to the worldwide opportunities for investment while investment in that country is financed by the worldwide pool of capital however in a cross country regression using period averaged saving and investment figures for sixteen oecd countries they obtain a significant coefficient close to unity and conclude that capital is rather immobile this result constitutes the feldstein horicka puzzle as it contradicts the widely held perception that capital is highly mobile across countries subsequent empirical work confirmed the close correlation though its implication for the degree of capital mobility is a moot point see tesar 1991 this paper contributes to the understanding of the puzzle on both theoretical and empirical counts first we present a theory based econometric specification for estimating saving investment correlations second we discuss the possible usefulness of the estimates for detecting capital mobility third we provide empirical results for the interesting case of norway we argue that feldstein and horioka s basic idea that the saving investment correlation contains information about international capital mobility is correct but that the interpretation of the estimated correlation value must be altered substantially in view of the results derived from modern macroeconomic models our research is motivated by the observation that various regression equations have been used to measure the saving investment correlation but that none of them has a firm theoretical foundation this in turn raises questions about the interpretation and comparability of the existing empirical results we propose an econometric specification that is founded in intertemporal general equilibrium models in which agents optimize under intertemporal budget constraints we show that time series studies have estimated misspecified equations and that cross section studies are seriously flawed because they neglect dynamics as a result the puzzle may turn out to be an artifact caused by measurement errors however the significance of reliable measurement of saving investment correlations goes beyond solving the feldstein horioka puzzle because they represent stylized facts open economy models should explain norway serves as a suitable example to cement our methodological arguments with empirical evidence thanks to its system of capital controls which were phased out during the 1970s and 1980s the oil discoveries and its small size we demonstrate that the failure to take structural breaks into account seriously distorts the picture making a strong case for careful diagnostic testing our main empirical result is that the feldstein horioka puzzle does not exist for norway the paper proceeds as follows in section ii we briefly summarize the state of the discussion regarding feldstein and horioka s findings in section iii we derive our specification from the theory compare it to the previous specifications and discuss how to make inferences about capital mobility in section iv we sketch major developments in the post war norwegian economy notably the abolition of capital controls and the emergence of the important oil sector section v presents the empirical results section vi summarizes and concludes ii the feldstein horioka puzzle many authors have confirmed feldstein and horioka s result of a high and stable correlation of saving and investment for oecd countries both in cross country studies and in time series studies

ability and power over production in the distribution of earnings t he aggregate distribution of earnings in all western countries is approximately lognormal over most of its range but the earnings of the top 10 or 20 of individuals follow the pareto form which generates a great excess of very high earnings compared with the tail of a lognormal distribution individuals at the top appear to be paid according to the job they perform rather than their ability this paper explains these features in terms of profit maximising behaviour from time to time a single new manager or management team improves a company s profit by millions of dollars per year this shows that a senior manager can influence the company s total output far more than a junior employee his greater influence over output derives from having much more control over the company s resources profit maximising companies offer high salaries for senior management jobs because even a small improvement in their performance leads to a worthwhile increase in output and competitive bidding for the best managers then drives their salaries up to high levels this in outline is the explanation for high earnings developed formally in the rest of this paper

how the market solves an assignment problem the matching of lawyers with legal claims in the market for lawyers observable data on promotion and turnover can be explained by reference to the idea that there is positive assortative mating of lawyers and legal claims there is a scale of resources effect under which it is optimal to assign larger claims to lawyers of higher quality in a law firm the institution of tenure performs a sorting function lawyers found to be of high quality are given tenured positions and the rest leave the value of legal claims handled by a firm determines its sorting problem which in turn determines its promotion ladder and turnover

estimating gender differences in access to jobs this paper proposes a new measure of gender differences in access to jobs based on a job assignment model this measure is the probability ratio of getting a job for a female and a male at each rank of the wage ladder we derive a nonparametric estimator of this access measure and estimate it for french full time executives aged 40 45 in the private sector our results show that the gender difference in the probability of getting a job increases along the wage ladder from 9 to 50 females thus have a significantly lower access to high paid jobs than to low paid jobs

learning about the nature of production from equilibrium assignment patterns this paper exploits empirically a key insight from lucas 1978 and rosen 1982 that the organization of production and the distribution of earnings across individuals are jointly determined by the equilibrium assignment of individuals to firms and hierarchical positions we study how different classes of production functions generate alternative equilibrium assignments we then use confidential census data on u s law offices to investigate the form that the production function should take to rationalize earnings patterns in legal services we argue that earnings patterns in this industry are consistent with a production function that is characterized by asymmetric sensitivity to the skill of agents in different organizational positions complementarity between managers and workers skill and scale effects in individual skill

reducing the cost of demand uncertainty through accurate response to early sales traditionally fashion products have incurred high losses due to stockouts and inventory obsolence because long lead times coupled with a concentrated selling season force all or at least most production to be committed before demand information is available under a quick response system lead times are shortened sufficiently to allow a greater portion of production to be scheduled in response to initial demand we model and analyze the decisions required under quick response and give a method for estimating the demand probability distributions needed in our model we applied these procedures with a major fashion skiwear firm and found that cost relative to the current informal response system was reduced by enough to increase profits by 60 relative to the cost that would have been incurred if no response were used optimized response reduces cost by enough to roughly quadruple profits

determinants of the current account balance in the united states this article studies the role of public and private imbalances in the behaviour of the current account balance in the united states in the context of an intertemporal model the estimation evaluates the effects of public and private imbalances on the dynamics of the current account correlation coefficients support the ricardian equivalence higher budget deficit correlates with a reduction in private consumption and an increase in private savings government saving does not vary significantly with macroeconomic variables in the short or in the long run in contrast fluctuations in government investment vary significantly with a number of economic variables in the long and in the short run accordingly fluctuations in the budget deficit are likely to be driven by fluctuations in public investment in contrast to government savings private savings vary significantly with macro variables in the long and in the short run fluctuations in private investment appear less evident compared to that in privat

on the optimal realignment of a contest the case of college football this article examines the relationship between demand and scheduling in college football we first derive two different metrics for team quality and then use those metrics to see how they impact attendance we find that there is a positive interaction between the quality of the teams then various simulations are run to see how attendance would change under different scheduling scenarios if teams are put into conferences based on the team quality measures the average per game attendance only rises 1 2 this is true if 1 year or 10 year quality measures are used however our simulation suggests that this effect would be more than offset mainly because schools with larger capacity would play fewer home games and so aggregate attendance would fall we discuss whether this effect would be mitigated by capacity adjustments in the longer term jel l83 z20 c78

timeliness and agglomeration an important element of the cost of distance is time taken in delivering final and intermediate goods we argue that time costs are qualitatively different from direct monetary costs such as freight charges the difference arises because of uncertainty unsynchronised deliveries can disrupt production and delivery time can force producers to order components before demand and cost uncertainties are resolved using several related models we show that this generates a hitherto unexplored mechanism for clustering if final assembly takes place in two locations and component production has increasing returns to scale then component production will tend to cluster around just one of the assembly plants

pay gap by gender in the tourism industry of brazil abstract this study aims to analyse wage gaps by gender in the brazilian tourism sector this involves investigating wage differences in order to identify the variables that determine the wages paid for these activities we sourced our statistics from the micro data collected by the national household sample survey pnad released by the brazilian institute of geography and statistics ibge in 2012 we deployed the decomposition of oaxaca 1973 and blinder 1973 to measure the differences in wages within the sector through this decomposition we conclude that gender pay discrimination exists in tourism in brazil demonstrating that women are less valued than men even when sharing the same job characteristics as a result we make policy recommendations and put forward suggestions for further research on the subject

international capital mobility in the long run and the short run can we still learn from saving investment data the idea to learn about international capital mobility from saving and investment data remains appealing our approach is based on var methods and overcomes some of the problems associated with saving investment regressions when the data are non stationary we propose a new measure of long run capital mobility that can be easily calculated as a by product of the estimation procedure of a cointegrated var in an application to historical us and british data we find long run capital mobility to have been remarkably stable over the century whereas variations in the mobility of capital primarily seem to have affected short run capital flows

gender wage differentials and educational mismatch an application to the spanish case this article aims to analyse gender wage differentials in spain by taking into account the levels of educational attainment and by studying whether the educational mismatch affects the gender wage gap focusing on returns to education evidence is found on the existence of educational mismatch and on its contribution to determine wages with women suffering greater wage penalties that are associated with educational mismatch furthermore although the gender wage gap is lower for individuals with low educational levels we find that the part of this gap due to differences in returns is greater in this group on the contrary the gender gap is greater among highly educated workers but in this case most of the wage differentials are due to differences in productive characteristics in any case our results suggest that gender wage discrimination tends to be greater for those workers who show educational mismatch

export sensitivity to time delays and the pattern of international trade a growing body of literature in the field of international trade highlights the increasing importance of the time delays associated with transporting goods over long distances and the differing eff

gender wage differentials by education in italy in this article we evaluate wage differentials in italy combining gender and education perspectives the main goal of this article is to verify whether the extent of the gender pay gap varies between highly and low educated workers and whether or not the role played by gender differences in characteristics and in market rewards is similar in the two groups we apply quantile regression analysis and an adaptation of the procedure suggested by machado and mata 2005 to evaluate the predicted wage gap at different points of the female wage distribution scale the analysis is carried out on the italian sample of the last available year of the european community household panel echp we show that the extent and the trend of the gap predicted across the female distribution is sharply different between groups with diverse educational levels in the case of low educated workers although the predicted gap is largely explained by differences in rewards lower levels of education or experience are responsible

testing the validity of the feldstein horioka puzzle for australia this article presents the details of an investigation into the relationship between investment and savings in australia over the period 1960 to 2007 using five time series techniques our results reveal that the feldstein horioka puzzle exists in a weak form with a lower saving retention coefficient granger causality tests illustrate that savings granger causes investment both in the short and long runs our results suggest australia could effectively adopt policies that focus on increasing investment through increasing domestic savings

the dynamics of inequality the past forty years have seen a rapid rise in top income inequality in the united states while there is a large number of existing theories of the pareto tail of the long run income distributions almost none of these address the fast rise in top inequality observed in the data we show that standard theories which build on a random growth mechanism generate transition dynamics that are too slow relative to those observed in the data we then suggest two parsimonious deviations from the canonical model that can explain such changes scale dependence that may arise from changes in skill prices and type dependence that is the presence of some high growth types these deviations are consistent with theories in which the increase in top income inequality is driven by the rise of superstar entrepreneurs or managers

transportation costs and international trade in the second era of globalization while the precise causes of postwar trade growth are not well understood declines in transport costs top the lists of usual suspects however there is remarkably little systematic evidence documenting the decline this paper brings to bear an eclectic mix of data in order to provide a detailed accounting of the time series pattern of shipping costs the ad valorem impact of ocean shipping costs is not much lower today than in the 1950s with technological advances largely trumped by adverse cost shocks in contrast air shipping costs have dropped an order of magnitude and airborne trade has grown rapidly as a result as a result international trade has also experienced a significant rise in speed

education matching and the allocative value of romance societies are characterized by customs governing the allocation of non market goods such as marital partnerships we explore how such customs affect the educational investment decisions of young singles and the subsequent joint labour supply decisions of partnered couples we consider two separate matching paradigms for agents with heterogeneous abilities one where partners marry for money and the other where partners marry for romantic reasons orthogonal to productivity or debt these generate different investment incentives and therefore have a real impact on the market economy while marrying for money generates greater investment efficiency romantic matching generates greater allocative efficiency since more high ability individuals participate in the labour market the analysis offers the possibility of explaining cross country differences in educational investments and labour force participation based on matching regimes

marriage markets and assortative mating with household public goods theoretical results and empirical implications this paper analyzes marriage market equilibria when the gains from marriage result from joint consumption of household public goods assuming transferable utility within marriage the paper proves that marriage markets will be characterized by positive assortative mating on wealth when spouses differ only in endowments and the gains to marriage result only from public goods when spouses differ in wages and household public goods are produced at home the results imply offsetting effects with public good economies creating an incentive for positive assortative mating on wages and gains from specialization creating an incentive for negative assortative mating on wages the results help explain the persistent lack of empirical support for becker s prediction of negative assortative mating on wages and have implications for empirical analysis of all joint living arrangement decisions

real effects of information frictions when the states and the kingdom became united abstract this paper exploits a unique historical experiment to estimate how information frictions distort international trade the establishment of the transatlantic telegraph in 1866 i use newly collected data on cotton prices trade and information flows from historical newspapers and find that the average and volatility of the transatlantic price difference fell after the telegraph while average trade flows increased and became more volatile using a trade model in which exporters use the latest news about a foreign market to forecast expected prices i estimate the efficiency gains of the telegraph to be equivalent to 8 percent of export value jel d83 f12 f14 l96 n71 n73

logistic infrastructure and the international location of fragmented production abstract casual evidence suggests that multinational companies increasingly look for places with adequate transport and logistic infrastructure to locate affiliates that participate in cross border production sharing yet there are no systematic empirical analyses examining how logistic infrastructure interacts with the location decisions made by multinationals most studies on the determinants of fdi address the issue of transportation logistics by examining the impact of distance on the relevant outcome but distance does not capture by itself the quality of the logistic systems in place we overcome this shortcoming in the literature by embedding indicators of infrastructure into an empirical framework that examines whether countries with adequate logistic systems attract more vertical fdi and particularly in industries that are more dependent on logistic services we find that logistic infrastructure positively impacts vertical fdi in addition to the impact typically found on distance a change from the first quartile to the third quartile of the distribution of logistic infrastructure is associated with an average increase in the number of vertically integrated subsidiaries equivalent to 29

empirical analysis of occupational hierarchies using data on u s engineers and the position of engineering jobs within firms this paper estimates a model of hierarchies within firms the model extends rosen s 1982 model of recursive production to two skills and multiple hierarchy levels the model generates an empirical model that is nested within a general roy 1951 model of self selection maximum likelihood estimates of the parameters of the production technology and the skill experience profiles are estimated the results suggest that approximately two thirds of changes in employment shares across hierarchy levels across time are explained by demographic shifts in the stock of engineering skills most of the returns to experience and to assignment to higher hierarchy levels within firms are caused by skill accumulation and self selection rather than technological dierences across hierarchy levels

capital mobility in saving and investment a time varying coefficients approach abstract this paper uses a model with time varying coefficients in order to track changes in feldstein horioka saving retention coefficients over time to the extent that such coefficients measure international capital mobility the main empirical findings are as follows first the stability of the saving retention coefficient is strongly rejected second capital has long been perfectly mobile in canada third capital mobility has never been high in the united states fourth capital was more mobile in japan and the united kingdom at the turn of the 20th century than it has been during the postwar period capital mobility has risen in argentina italy and sweden since around 1970 finally capital mobility for most of the countries considered has not monotonically increased during the postwar period

field of study earnings and self selection why do individuals choose different types of post secondary education and what are the labor market consequences of those choices we show that answering these questions is difficult because individuals choose between several unordered alternatives even with a valid instrument for every type of education instrumental variables estimation of the payoffs require information about individuals ranking of education types or strong additional assumptions like constant effects or restrictive preferences these identification results motivate and guide our empirical analysis of the choice of and payoff to field of study our context is norway s post secondary education system where a centralized admission process covers almost all universities and colleges this process creates credible instruments from discontinuities which effectively randomize applicants near unpredictable admission cutoffs into different fields of study at the same time it provides us with strategy proof measures of individuals ranking of fields taken together this allows us to estimate the payoffs to different fields while correcting for selection bias and keeping the next best alternatives as measured at the time of application fixed we find that different fields have widely different payoffs even after accounting for institutional differences and quality of peer groups for many fields the payoffs rival the college wage premiums suggesting the choice of field is potentially as important as the decision to enroll in college the estimated payoffs are consistent with individuals choosing fields in which they have comparative advantage we also test and reject assumptions of constant effects or restrictive preferences suggesting that information on next best alternatives is essential to identify payoffs to field of study

measuring and decomposing the gender pay gap a new frontier approach abstract the gender pay gap measures the differences in the wages earned by female workers when compared to male workers accurately measuring the gender pay gap is an important exercise in order to assess how far we are from the ideal of equal pay for work of equal value determining the different sources of the gender pay gap is also very important in order to design appropriate policies for eliminating this gap we develop an enhanced method to measure and decompose the gender pay gap this method is based on the data envelopment analysis dea technique and on the malmquist index mi we use dea and the mi to construct an index reflecting an adjusted measure of the gender pay gap taking into account multiple productive characteristics and multiple types of pay furthermore we propose a decomposition of the gender pay gap into four components same gender pay gap cross gender frontier gap magnitude productive characteristics bias and pay package bias the method is applied to data relative to 15 712 men and 17 175 women working as business and administration associate professionals in the finance and insurance industry in 20 countries the results reveal the existence of a gender pay gap in all countries and that the value of the gap and of its components vary considerably between countries requiring different policies to tackle it

hedging price volatility using fast transport abstract purchasing goods from distant locations introduces a significant lag between when a product is shipped and when it arrives these transit lags are trade barriers for firms facing volatile demand who must place orders before knowing the resolution of demand uncertainty we provide a model in which airplanes bring producers and consumers together in time fast transport allows firms to respond quickly to favorable demand realizations and to limit the risk of unprofitably large quantities during low demand periods the model predicts that the likelihood and extent to which firms employ air shipments is increasing in the volatility of demand they face decreasing in the air premium they must pay and increasing in the contemporaneous realization of demand we confirm all three conjectures using detailed us import data fast transport thus provides firms with a real option to smooth demand volatility on international markets and we provide simple calculations of that option value this enables us to identify how the option value relates to goods characteristics and to changes in air transport premia associated with technological and policy change including the introduction of jet engines and liberalization of trade in air services

the housing market s of san diego this paper uses an assignment model to understand the cross section of house prices within a metro area movers demand for housing is derived from a lifecycle problem with credit market frictions equilibrium house prices adjust to assign houses that dier by quality to movers who dier by age income and wealth to quantify the model we measure distributions of house prices house qualities and mover characteristics from micro data on san diego county during the 2000s boom the main result is that cheaper credit for poor households was a major driver of prices especially at the low end of the market

international capital mobility what do national saving investment dynamics tell us abstract we interpret the relationship between national saving and investment in the long run as reflecting a solvency constraint and interpret the ease with which a country can run current account imbalances in the short run before it has to ultimately reverse the transaction at some future date to satisfy the solvency constraint as being positively related to the degree of international capital mobility we apply panel error correction techniques to data for 20 oecd countries from 1960 to 1999 we find that saving and investment display a long run cointegration relationship that is consistent with the interpretation that a long run solvency constraint is binding for each country over time however deviations from this long run equilibrium relation have become more persistent which suggests that capital mobility has increased

distance time and specialization lean retailing in general equilibrium transport time increases with distance traveled and time is valuable we show the implications of these facts for global specialization and trade products where timely delivery is important will be produced near the source of final demand where wages will be higher as a result in the model timely delivery is important because it allows retailers to respond to final demand fluctuations without holding costly inventories and timely delivery is possible only from nearby locations using a unique dataset that allows us to measure the retail demand for timely delivery we show that the sources of u s apparel imports have shifted in the way predicted by the model with products for which timeliness matters increasingly imported from nearby countries jel f1 transporting goods and people costs time and money and both transport fees and time in transit generally increase with the distance traveled these facts imply an incentive to economize on distance and the equilibrium effects

explaining saving investment correlations national saving and investment rates are highly positively correlated in virtually all countries this is puzzling as it apparently implies a low degree of international capital mobility this paper shows that the observed positive correlation between national saving and investment rates arises naturally within a quantitatively restricted equilibrium model with perfect mobility of financial and physical capital the model is consistent with the fact that saving investment correlations are larger for larger countries but are still substantial for small countries further the model is consistent with the finding that current account deficits tend to be associated with investment booms copyright 1993 by american economic association

intertemporal optimizing models of trade and current account balance a survey abstract this study surveys the intertemporal optimizing models of trade and current account balance that were developed calibrated and empirically tested since they came into vogue in the 1980s the implications of these models often differ from those of static and dynamic conventional non optimizing models the literature on optimizing models has not only grown reasonably fast but has also witnessed significant advances in methodology and these models have culminated into a distinct strand of new open economy macroeconomics the studies conducted until the late 1980s have used deterministic perfect foresight models while several studies conducted since the 1990s relax the perfect foresight and certainty equivalence assumptions and develop stochastic dynamic general equilibrium models to account for uncertainty confronting the optimizing agents the future research needs to explore the possibility of tracing any preferred specification of household preferences model the effect of time varying discount factor on household utility function and intertemporal budget constraint examine the role of costs in international trade place a parallel emphasis on the empirical verifications of theoretical propositions examine the relative performance of optimizing vis a vis non optimizing models and rationalize the extreme propositions of perfect and imperfect capital mobility in the wake of moderately open capital accounts

a spillover based theory of credentialism i propose a model in which credentials such as diplomas are instrumentally valuable to workers the model avoids an important criticism of standard job market signalling models by tying a worker s wage to their output a worker s productivity is influenced by the skills of their co workers where such skills arise from an ability augmenting investment that is made prior to matching with co workers credentials allow workers to demonstrate their investment to the labour market thereby allowing them to match with high skill co workers in equilibrium despite the positive externality associated with a worker s investment i show how overinvestment is pervasive in equilibrium

overeducation undereducation and the british labour market this paper addresses the issue of overeducation and undereducation using for the first time a british dataset which contains explicit information on the level of required education to enter a job across the generality of occupations three key issues within the overeducation literature are addressed first what determines the existence of over and undereducation and to what extent are over and undereducation substitutes for experience tenure and training second to what extent are over and undereducation temporary or permanent phenomena third what are the returns to over and undereducation and do certain stylized facts discovered for the us and a number of european countries hold for britain

a note on aggregation of skills and labor quality we use a unique new data set that combines data on individual workers and their employers to estimate marginal productivity differentials among different types of workers we then compare these to estimated relative wages leading to new evidence on

hedonic prices and implicit markets estimating demand and supply functions for differentiated products in choosing the level of quality to purchase the buyer of a differentiated product also chooses a point on the marginal price schedule for that product hence in general the demand functions for product characteristics cannot be consistently estimated by ordinary least squares market equilibrium results in a matching of characteristics of demanders and suppliers this matching restricts the use of buyer and seller characteristics as instruments when estimating demand and supply functions for product characteristics the paper develops these issues a stochastic structure for hedonic equilibrium models is then proposed identification results are presented and estimation procedures are outlined

the comparative advantage of cities abstract what determines the distributions of skills occupations and industries across cities we develop a theory to jointly address these fundamental questions about the spatial organization of economies our model incorporates a system of cities their internal urban structures and a high dimensional theory of factor driven comparative advantage it predicts that larger cities will be skill abundant and specialize in skill intensive activities according to the monotone likelihood ratio property we test the model using data on 270 us metropolitan areas 3 to 9 educational categories 22 occupations and 19 industries the results provide support for our theory s predictions

allocation of individuals to job levels under rationing summary we augment an ordered response model for the job level at which individuals desire to work with allowance for individual reporting of a discrepancy between actual and desired job level and we also investigate possible biases from restricting the observations to the employed and omitting the unemployed we find that the latter bias can be ignored and interpret this as evidence that the unemployed are not choosier than the employed people claiming inadequate capability utilization are not markedly differently allocated than those claiming a proper match women s lower job levels cannot be explained from rationing by capability utilization

self selection bias in longitudinal estimation of wage gaps cross sectional regression analyses of wage gaps may be biased by omission of unobserved worker characteristics recent studies therefore have used longitudinal data to difference out the effects of such variables this paper however shows that self selection of job changers may cause longitudinal estimation of wage gaps to be inconsistent

mismatch in the spanish labor market overeducation the objective of this article is to explain the job match which is assessed by comparing attained education and job required education as reported by workers we frame our empirical work according to the occupational mobility theory using a cross section of workers from a representative survey of the spanish labor force we consider overeducated workers to be those who report that the level of education their jobs require is below the level of education they have attained our results indicate that overeducated workers have less experience decreased on thejob training and higher turnover than other comparable workers we also observe an improvement in the job match over age and mobility

the dynamic effects of aggregate demand and supply disturbances we interpret fluctuations in gnp and unemployment as due to two types of disturbances disturbances that have a permanent effect on output and disturbances that do not we interpret the first as supply disturbances the second as demand disturbances demand disturbances have a hump shaped mirror image effect on output and unemployment the effect of supply disturbances on output increases steadily over time peaking after two years and reaching a plateau after five years

worker allocation hierarchies and the wage distribution economists have traditionally viewed the allocation of workers among jobs through the concept of comparative advantage this paper investigates hierarchical production models which display an absence of comparative advantage in order to demonstrate that for hierarchical production there is a second allocating factor which plays an important role two results are found first the allocation of workers among jobs tends to match high ability workers with positions which value ability highly second despite the fact that the models display an absence of comparative advantage i e the standard theoretical explanation for why wage distributions might be skewed the models wage distributions are skewed to the right relative to the underlying ability distributions

import dynamics and demands for protection what kinds of changes in foreign competition lead domestic industries to seek import protection to address this question this paper uses detailed monthly u s import data to investigate changes in import composition during a 24 month window immediately preceding the filing of a petition for protection a decomposition methodology allows a comparison of imports from two groups of countries supplying the same product those that are named in the petition and those that are not the same decomposition can be applied to products quite similar to the imports in question but not subject to a petition the results suggest that industries typically seek protection when faced with a specific pattern of shocks first a persistent positive relative supply shock favors imports from named countries second a negative demand shock hits imports from all sources just prior to domestic industries petition for protection the relative supply shock is a broad one it applies both to named commodities and to the comparison product group the import demand shock by contrast is narrow hitting only named products the latter shock is also large import growth over the two year window is 15 percentage points lower in named products than in reference products with most of this gap arising in the final two quarters before the petition the negative import demand shock appears to be a key event in the run up to the filing of a petition it has been missed by previous studies using more aggregated data

a century of current account dynamics abstract recent globalization trends have refocused attention on the historical evolution of international capital mobility over the long run the issue is examined here using time series analysis of current account dynamics for fifteen countries since circa 1850 the inter war period emerges as an era of low capital mobility and only recently can we observe a tentative return to the degree of capital mobility witnessed during the late nineteenth century the analysis of saving and investment dynamics also helps make sense of the frequently observed high correlation of saving and investment rates in historical data

sorting through search and matching models in economics toward understanding assortative matching this is a self contained introduction to research on search and matching we first explore the nontransferable and perfectly transferable utility matching paradigms and then a unifying imperfectly transferable utility matching model motivated by some unrealistic predictions of frictionless matching we flesh out the foundational economics of search theory we then revisit the original matching paradigms with search frictions we finally allow informational frictions that often arise such as in college student sorting

frictional assignment i efficiency abstract this paper examines the two sided matching problem where the agents on each side of the market are heterogeneous and the matching process is time consuming this is cast in a labor market setting where workers of different skills match with different machine qualities i characterize the efficient allocation and then show that it can be decentralized by a market mechanism the efficient assignment is not always positively assortative despite the fact that machine qualities and skills are complementary in production to decentralize the efficient allocation the market mechanism requires the firms to post wages and commit each machine quality to a particular skill implications on wage inequality are briefly examined journal of economic literature classification numbers j31 e24 j64

current account solvency and the feldstein horioka puzzle in this paper we suggest an alternative explanation of the high cross section association between shares of saving and investment in gdp which feldstein and horioka 1980 interpret as evidence of low capital mobility in oecd countries saving and investment shares appear to be i i we show that a solvency constraint implies that the current balance is stationary and thus that saving and investment cointegrate with a unit coefficient irrespective of the degree of capital mobility it is this long run relation that the fh cross section regression captures econometric results for 23 oecd countries over the 1960 92 period are consistent with this explanation

labor supply as a choice among latent jobs unobserved heterogeneity and identification this paper discusses aspects of a framework for modeling labor supply where the notion of job choice is fundamental in this framework workers are assumed to have preferences over latent job opportunities belonging to worker specific choice sets from which they choose their preferred job the observed hours of work and wage is interpreted as the job specific hours and wage of the chosen job the main contribution of this paper is an analysis of the identification problem of this framework under various conditions when conventional cross section micro data are applied

the impact of surplus schooling on earnings some additional findings this paper examines the impact of overeducation or surplus schooling on earnings overeducated workers are defined as those with educational attainments substantially above the mean for their specific occupations two models are estimated using data from the 1980 census though our models data and measure of overeducation are different from those used by rumberger 1987 our results are similar our results show that overeducated workers often earn less than their adequately educated and undereducated counterparts

overeducation in the labour market abstract this paper presents a review of the literature on overeducation the paper assesses the consistency of overeducation within the context of a number of theoretical frameworks including human capital theory hct and assignment theory the analysis goes on to discuss the various measurement controversies associated with the study of overeducation in order to provide an assessment of the extent to which the impacts of the phenomenon represent an economic reality as opposed to a statistical artefact after reviewing the literature it is concluded that the impacts of overeducation are likely to be non trivial and that the phenomenon may potentially be costly to individuals and firms as well as the economy more generally the existence of overeducation also raises some doubts with respect to the validity of some of the central assumptions and predictions of hct that are unlikely to be fully explained by gaps in the standard wage equation framework

self selection and the distribution of hourly wages this article formulates and estimates alternative equilibrium models of industrial wage determination and self selection in explaining industrial wage differentials we find that it is important to account for heterogeneous sector specific skills and self selection decisions by agents concerning their sector of employment the classical roy model is rejected so is an efficiency units model of the labor market a revised roy model that accounts for comparative advantage in the choice of industrial sectors and choice between market and nonmarket work is much more successful in explaining cross section wage distributions and their evolution over time

aggregation bias in elasticities of substitution and the minimum wage paradox while the employment effects of minimum wages are usually reported to be small suggesting low substitutability between skill types direct estimates suggest a much larger degree of substitutability this article argues that this paradox is largely due to a bias induced by the aggregation of skill types into broad categories an assignment model is applied where skilled workers have a comparative advantage in complex jobs the implied pattern of substitutability reveals the sources of the bias estimation results for the united states show elasticities of complementarity to be underestimated by up to a factor 2 5 the methods laid out likewise can be applied to other markets where different quality types are close substitutes such as the housing market

education and skills mismatch in the italian graduate labour market this paper focuses on education and skills mismatch among italian graduates indicators for over and under utilization of education and under utilization of skills are included as explanatory factors in a wage equation testing theories that could explain the effect of over schooling on wages we find little evidence to support assignment theory and also identify a relatively weak wage effect arising from educational mismatch associated with employers as opposed to employees perceptions of the job requirements our interpretation is that some employers have re categorized jobs as requiring a degree when they were previously filled by non graduates and many have not altered pay scales accordingly

returns to talent and the finance wage premium to study the role of talent in finance workers pay we exploit a special feature of the french higher education system wage returns to talent have been significantly higher and have risen faster since the 1980s in finance than in other sectors both wage returns to project size and the elasticity of project size to talent are also higher in this industry last the share of performance pay varies more for talent in finance these findings are supportive of finance wages reflecting the competitive assignment of talent in an industry that exhibits a high complementarity between talent and scale received october 11 2017 editorial decision september 4 2018 by editor stijn van nieuwerburgh authors have furnished an internet appendix which is available on the oxford university press web site next to the link to the final published paper online

heterogeneous firms and the organization of production firms in the same industry exhibit systematic differences in the organization of production and the structure of employment entrepreneurial ability is the specific scarce input that limits the size of a firm this input must be allocated to two activities coordinating production and monitoring workers able entrepreneurs can convert calendar time into larger supplies of coordinating effort that enable them to assemble large firms greater ability implies a higher shadow price of time which increases the implicit costs of monitoring a dispersion of entrepreneurial abilities generates an equilibrium size distribution of firms differences in monitoring costs affect the choice of worker productivities the design of products and the organization of production the monitoring cost hypothesis advanced in this paper goes a long way in explaining the equilibrium of an industry containing heterogeneous firms that differ in size and behavior

endogenous pricing to market and financing costs abstract this paper explains why relative ppp should hold more tightly in emerging markets and why pricing to market would be observed more frequently in the oecd countries it studies the endogenous determination of pricing to market in a real option model with time dependent transportation costs where the future terms of trade are random allowing time dependent transportation costs adds a dimension of investment to the pre buying of imports implying that financial considerations determine the frequency of pricing to market and the deviations from relative ppp if the expected discounted cost of last minute delivery is higher than pre buying one exercises the option of spot market imports if the realized terms of trade are favorable enough pricing to market is observed in countries characterized by low terms of trade volatility and low financing costs in these circumstances imports are pre bought and the spot market for imports is inactive in countries where the financing costs and the terms of trade volatility are high few imports are pre bought the price of imports is determined by the realized real exchange rate and a version of relative ppp holds with an intermediate level of terms of trade volatility and of financing costs a mixed regime is observed if the realized real exchange rate is weak pricing to market would prevail increasing consumers welfare by shielding them from the adverse purchasing power consequences of weak terms of trade if the realized real exchange rate is favorable enough more imports are purchased in the spot market and the relative ppp would hold higher financing costs increase the cost of pre buying imports reducing thereby the frequency of pricing to market increasing the expected relative price of imports reducing the expected deviations from relative ppp and reducing welfare

investment and saving in angola and the feldstein horioka puzzle this article analyses the relationship between investment and savings for angola using the feldstein horioka puzzle with monthly data from january 2000 to december 2013 integer and fractional integration and cointegration techniques are employed to investigate the relationship between investment and savings several regression specifications are employed concluding that the feldstein horioka puzzle is not validated for the angolan economy policy implications are derived

the dynamics of short and long run capital mobility evidence from a time varying parameter error correction model this article analyses the dynamic evolution of capital mobility in eight organization for economic co operation and development oecd countries over the period 1850 to 1992 we estimate an error correction model of saving and investment that allows to distinguish between short and long run capital mobility the parameters of the error correction model are allowed to be time vary ing and are estimated using the kalman filter and maximum likelihood technique we find that both short and long run capital mobility was very high at the end of the nineteenth century but since then decreased in most countries however the magnitude of changes in long run capital mobility is very small while the absolute change of short run capital mobility is substantial

the incidence of and returns to overeducation in the uk the 1991 wave of the british household panel survey is used to examine the extent of and the returns to overeducation in the uk about 11 of the workers are overeducated while another 9 are undereducated for their job the results show that the allocation of female workers is more efficient than the allocation of males the probability of being overeducated decreases with work experience but increases with tenure overeducated workers earn less while undereducated workers earn more than correctly allocated workers both the hypothesis that productivity is fully embodied and the hypothesis that productivity is completely job determined are rejected by the data it is found that there are substantial wage gains obtainable from a more efficient allocation of skills over jobs

risky business the decline of defined benefit pensions and firms shifting of risk since the early 1980s employment in the united states has undergone significant transformation as the large corporations that once safeguarded employees with stable jobs and rewards for loyalty have replaced these employment relationships with ones based on cost containment and flexibility one important consequence of these developments is that firms have abdicated their role as a critical risk bearer in society although evidence suggests that firms have increasingly shifted market risks onto their workforce to date there have been few detailed analyses exploring what factors have driven this phenomenon this study adds to our understanding of why firms have transferred risk to their employees by examining the decline of a highly institutionalized practice wherein large u s firms used to bear retirement risk the defined benefit db pension plan through a detailed analysis i show that variance in the presence power and interests of shareholders and employees at the firm level differentially affect a firm s willingness to shift the risk of retirement onto its workers specifically i demonstrate empirically that different types of shareholders have differential effects on a firm s retirement practices suggesting that the changing equity ownership structure of large u s firms has played a key role in how risk is allocated between workers and firms declines in employee power have also played a role because firm levels of unionization positively affect rates of db participation for both unionized and nonunionized workers

search sorting and urban agglomeration studies have suggested that urban agglomeration enhances productivity by facilitating the firm worker matching process this article develops a model that formalizes this notion and demonstrates that when firm capital and worker skill are complementary in production urban agglomeration will tend to generate more efficient yet segregated matches as a result not only will local market size be positively associated with average productivity it will also generate greater between skill group wage inequality and a higher expected return to skill acquisition recent data from the counties and metropolitan areas of the united states is consistent with each of these implications

saving investment dynamics and capital mobility in the us and japan abstract this paper points out that a high long run correlation between saving and investment is better interpreted as reflecting the operation of a country s intertemporal budget constraint rather than as an indicator of capital mobility inferences about capital mobility can instead be made from the divergent short run dynamic responses of saving and investment to shocks using post war quarterly data for the us and japan the paper assesses the characteristics of saving and investment behavior under different regulatory environments it finds mixed evidence of changes in the short run dynamics of saving and investment that suggest increased capital mobility in the 1980s

a meta analysis of the international gender wage gap abstract since the early 1970s a number of authors have calculated gender wage differentials between women and men of equal productivity this meta study provides a new quantitative review of this vast amount of empirical literature on gender wage differentials as it concerns not only differences in methodology data and time periods but also different countries we place particular emphasis on a proper consideration of the quality of the underlying study which is done by a weighting with quality indicators the results show that data restrictions i e the limitation of the analysis to new entrants never marrieds or one narrow occupation only have the biggest impact on the resulting gender wage gap moreover we are able to show what effect a misspecification of the underlying wage equation like the frequent use of potential experience has on the calculated gender wage gap over time raw wage differentials worldwide have fallen substantially however most of this decrease is due to better labor market endowments of females

international capital mobility amongst the major industrialised countries too little or too much this paper examines capital flows among the major industrialized countries with a view to assessing m feldstein and c horioka s 1980 claim that international capital mobility is limited it argues that saving investment correlation tests are inherently flawed and proposes an alternative methodology for testing the degree of international capital mobility it finds that capital flows have been excessive in the sense that they are driven by speculative forces rather than by economic fundamentals copyright 1995 by royal economic society

the importance of bundling in a gorman lancaster model of earnings the idea that the labor market of individuals can be decomposed into payments to separate productive attributes has an enduring appeal in economics assuming that demographic groups differ only in their endowments of productive characteristics it is possible to rationalize observed demographic earnings differentials without invoking the arguments that characteristics specific to a particular demographic group are direct objects of employer demand by aggregating skills over all demographic groups it is possible to produce a theory of the market determination of the prices of skills held in different amounts by different demographic groups this paper considers conditions under which characteristics are uniformly priced across sectors of a multisector economy the paper presents empirical evidence that rejects uniform pricing of characteristics as a description of the us labor market bundling may account for this evudence but other hypotheses do as well authors

housing assignment with restrictions theory and evidence from stanford university s campus this paper studies housing markets where a subset of houses in a restricted area is available exclusively to a subset of eligible buyers an empirical part shows that houses on stanford campus available only to faculty trade at substantial discounts to comparable houses off campus the theoretical part describes an assignment model with heterogeneous houses and buyers which predicts such discounts if the matchup of quality and buyer pools is sufficiently different inside versus outside the restricted area the restriction can distort allocations by making eligible buyers choose either higher or lower qualities than ineligible buyers with the same characteristics

pay technology and the cost of worker absence i introduction the complexity of patterns of worker absence is well known but is yielding reluctantly to studies that use highly detailed information about individual workers and their work environments to date these studies have focussed on how specific contractual details affect worker absenteeism rates 1 in this paper we instead take an equilibrium perspective where we assume heterogeneous firms and heterogeneous workers participate in a competitive labor market by understanding why firms with different technologies may have different policies toward absenteeism we can begin to explain observed differences in absenteeism rates across workers and firms the empirical framework is based on coles and treble 1996 which considers an equilibrium assignment model with heterogeneous firms and workers the standard assignment framework 2 assumes that each filled job is characterized by one machine of quality q and one employee with skill level s a competitive equilibrium yields a wage schedule w and an assignment rule q where a worker of skill s is hired at wage w w s by a firm holding machine q q s coles and treble 1996 do not assume that workers are differently skilled instead workers have different propensities to go absent also instead of a one worker one machine production process firms utilize different production technologies some use an assembly line technology where output requires that a sufficient number of workers show up for work and others use a linear production technology in which there are constant marginal returns to labor for reasons that will become clear a competitive equilibrium yields a wage schedule and an assignment rule that depend on worker propensities to go absent specifically workers with a lower propensity to go absent earn a higher wage and are employed in firms using assembly line technologies the key insight is that firms who operate assembly line technologies have a different shadow cost of absenteeism from those which operate a linear technology as in weiss 1985 and coles and treble 1993 in the latter technology an absence by one particular worker does not affect the marginal productivity of other workers at the firm this is not true in an assembly line firm or in production functions where labor inputs are strict complements as in kremer 1993 coles and treble 1996 consider a market equilibrium in which workers are also heterogeneous say workers have different family responsibilities in this case a competitive labor market implies equilibrium sorting by firms and workers assembly line firms require a low level of absenteeism and pay a relatively high wage to compensate workers for attending work reliably we refer to this as the shadow cost of absenteeism workers who have a comparative advantage in attending work reliably say those who do not have to look after children when the children are sick take employment in assembly line firms and enjoy the wage premium attached to employment there we refer to this as the shadow price of absenteeism conversely those who appreciate greater flexibility in work attendance take employment in the linear technology firms and in equilibrium earn a lower average wage rate although absenteeism may be costly to firms observed absenteeism rates are not necessarily inefficient the worker who misses a day at work to look after sick children or enjoy a sports event is expressing a trade off between workplace production and home production where home productivity is perhaps subject to idiosyncratic shocks efficient contracting implies that firms and workers agree to an acceptable absenteeism rate and a compensating wage differential efficient sorting implies that those workers who can commit to attending work reliably accept employment in assembly line occupations and so earn a wage premium reflecting the shadow price of absenteeism our goal is to identify and measure this shadow price using a unique data set from france

inter industry mobility and the cyclical upgrading of labor we investigate whether a market clearing model is consistent with industry employment and wage patterns related to the cyclical upgrading of labor we demonstrate that roy s 1951 market clearing

does unmeasured ability explain inter industry wage differentials this paper provides empirical assessments of the two leading explanations of measured inter industry wage differentials 1 true wage differentials exist across industries and 2 the measured differentials simply reflect unmeasured differences in workers productive abilities first we summarize the existing evidence on the unmeasured ability explanation second we construct a simple model which shows that if matching is important then endogenous job change decisions can create important self selection biases even in first differenced estimates of industry wage differentials third we analyze a sample that approximates the experiment of exogenous job loss we find that i the wage change experienced by a typical industry switcher closely resembles the difference in the relevant industry differentials estimated in a cross section and ii pre displacement industry affiliation plays an important role in post displacement wage determination

why has house price dispersion gone up we calibrate a dynamic general equilibrium island model to investigate the 30 year increase in the level of house prices and their dispersion across u s metropolitan areas the model is based on two main assumptions households o w in and out metropolitan areas in response to local productivity shocks and the housing supply cannot adjust instantly because of technological and regulatory constraints the calibration reveals that the observed tightening of housing supply regulation cannot quantitatively account for the rise in the level and dispersion of house prices in equilibrium workers o w out of tightly regulated towards less regulated metropolitan areas undoing most of the price impact of local supply restrictions in contrast the observed increase in wage dispersion across metropolitan areas does create the observed increase in the level and dispersion of house prices workers o w towards exceptionally productive metropolitan areas and drive house prices up the calibration also suggests that the welfare eects of housing supply regulation are large when wages become more dispersed

market forces and ceo pay shocks to ceo demand induced by ipo waves i develop a simple competitive equilibrium model and derive the prediction that ceo pay size elasticity increases when more firms compete for an inelastic supply of managers using industry level ipo waves as a proxy for increased competition for ceos i find that pay size elasticity increases by 6 with a one standard deviation increase in ipo activity this effect is stronger in specialized industries in addition increased ipo activity leads to a greater likelihood of executive transitions between firms these findings indicate that market forces play a key role in the determination of ceo pay received august 6 2015 editorial decision september 24 2016 by editor francesca cornelli

gender pay gaps and the restructuring of graduate labour markets in southern europe in this article we investigate whether education job mismatches and growing occupational diversity are important explanatory factors of gender pay gaps amongst university graduates in southern europe namely in portugal spain and italy we use standard decomposition techniques and test the implications of controlling for selection bias our results indicate that over education and greater occupational segregation associated with the emergence of new graduate job profiles are important determinants of earnings inequality whilst our focus is on graduates early careers demonstrating that occupational assignment and selection into employment shape gender pay gaps amongst the highly skilled provides a more pessimistic view on the ability of educational expansion or equal pay legislation to significantly reduce gender pay inequality southern european economies are also particularly interesting to look at since there may be a greater degree of mismatch between the pace of higher education expansion and the changes in the job structure making women particularly vulnerable to over education

international real business cycles we ask whether a two country real business cycle model can account simultaneously for domestic and international aspects of business cycles with this question in mind we document a number of discrepancies between theory and data the most striking discrepancy concerns the correlations of consumption and output across countries in the data outputs are generally more highly correlated across countries than consumptions in the model we see the opposite

the effect of risk on the ceo market this article presents a market equilibrium model of ceo assignment pay and incentives under risk aversion and moral hazard each of the three outcomes can be summarized by a single closed form equation in the presence of moral hazard assignment is distorted from positive assortative matching on firm size as firms with higher risk or disutility choose less talented ceos such firms also pay higher salaries in the cross section but economywide increases in risk or the disutility of being a ceo do not affect pay the strength of incentives depends only on the disutility of effort and is independent of risk and risk aversion if the ceo can affect firm risk incentives rise and are increasing in risk and risk aversion we calibrate the losses from various forms of poor corporate governance such as failures in monitoring and inefficiencies in ceo assignment jel g34 j33 this article presents a market equilibrium model of ceo assignment pay and incentives risk averse managers of different talents are hired in a competitive market by heterogeneous firms which vary in their size risk and level of effort required the level of pay drives the assignment of talent to firms the strength of incentives induces the efficient effort level and is determined by an optimal contracting approach our main contribution is to incorporate risk into a ceo market equilibrium in a tractable manner a large empirical literature has shown that risk is a firstorder determinant of compensation contracts demsetz and lehn 1985 garen 1994 core and guay 1999 oyer and schaefer 2004 peters 2009 peters and wagner 2009 but most theories assume risk neutrality this assumption is
