Wage dispersion : why are similar workers paid differently by Dale Mortensen( Book )

18 editions published between 2003 and 2005 in English and Undetermined and held by 517 WorldCat member libraries worldwide

"Observable differences in workers doing the same job account for only 30 percent of wage variation. In Wage Dispersion Dale Mortensen examines the reasons for pay differentials in the other 70 percent. He finds that these differentials, or wage dispersion, are largely the result of job search friction (which arises when workers do not know the wages offered by all employers) and cross-firm differences in wage policy and productivity."--Jacket

A selection of key papers from the winners of the Nobel Memorial Prize 2010. It features their most important work on unemployment, labour market dynamics, and the equilibrium search model
More on unemployment and vacancy fluctuations by Dale Mortensen( Book )

16 editions published between 1999 and 2005 in English and held by 49 WorldCat member libraries worldwide

"Shimer (2005a) argues that the Mortensen-Pissarides equilibrium search model of unemployment explains only about 10% of the response in the job-finding rate to an aggregate productivity shock. Some of the recent papers inspired by his critique are reviewed and commented on here. Specifically, we suggest that the sole problem is neither the procyclicality of the wage nor the failure to account fully for the opportunity cost of employment. Although an amended version of the model, one that accounts for capital costs and counter cyclic involuntary separations, does much better, it still explains only 40% of the observed volatility of the job-finding rate. Finally, allowing for on-the-job search does not improve the amended models implications for the amplification of productivity shocks"--National Bureau of Economic Research web site
An empirical model of growth through product innovation by Rasmus Lentz( Book )

12 editions published in 2005 in English and held by 36 WorldCat member libraries worldwide

Productivity dispersion across firms is large and persistent, and worker reallocation among firms is an important source of productivity growth. The purpose of the paper is to estimate the structure of an equilibrium model of growth through innovation that explains these facts. The model is a modified version of the Schumpeterian theory of firm evolution and growth developed by Klette and Kortum (2004). The data set is a panel of Danish firms than includes information on value added, employment, and wages. The model's fit is good and the structural parameter estimates have interesting implications for the aggregate growth rate and the contribution of worker reallocation to it
Taxes, subsidies and equilibrium labour market outcomes by Dale Mortensen( Book )

9 editions published between 1991 and 2001 in English and held by 29 WorldCat member libraries worldwide

We explore the effects of taxes and subsidies on job creation, job destruction, employment and wages in the Mortensen-Pissarides version of the search and matching equilibrium framework. Qualitative analytical results show that wage and employment subsidies increase employment, especially of low skill workers, and also increase wages. A job creation or hiring subsidy reduces unemployment duration but increases incidence with an ambiguous effect on overall employment. A firing tax has the reverse effects but the same indeterminacy. In the special case of a competitive search equilibrium, in which search externalities are internalized, there is a first best configuration. The results are: no tax on the wage, an employment subsidy that offsets the distortions on the job destruction margin induced by unemployment compensation and employment protection policy, as well as a hiring subsidy equal to the implicit tax on severance imposed by any form of employment protection. The costs of these and other policies are financed by a non-distortionary consumption tax. Computational experiments confirm this ideal also determines the direction in which marginal improvements can be made both in terms of efficiency and in terms of improving low skill worker employment and wage outcomes

Island matching by Dale Mortensen( Book )

8 editions published in 2007 in English and held by 20 WorldCat member libraries worldwide

A synthesis of the Lucas-Prescott island model and the Mortensen- Pissarides matching model of unemployment is studied. By assumption, all unmatched workers and jobs are randomly assigned to islands at the beginning of each period and the number of matches that form on a particular island is the minimum of the two realizations. When calibrated to the recently observed averages of U.S. unemployment and vacancy rates, the model fits the observed vacancy-unemployment Beveridge relationship very well and implies an implicit log linear relationship between the job finding rate and the vacancy-unemployment relationship with an elasticity near 0.5. The constrained efficient solution to the model is decentralized by a equilibrium outcome in which wages on each island are determined by a modified auction. Although the efficient solution explains only about 25% of the observed volatility in the U.S. vacancy-unemployment ratio, an equilibrium outcome in which wages are determined as the solution to a strategic bargaining game explains almost all of it

Wage dispersion in the search and matching model with intra-firm bargaining by Dale Mortensen( Book )

6 editions published in 2009 in English and held by 12 WorldCat member libraries worldwide

Matched employer-employee data exhibits both wage and productivity dispersion across firms and suggest that a linear relationship holds between the average wage paid and a firm productivity. The purpose of this paper is to demonstrate that these facts can be explained by a search and matching model when firms are heterogenous with respect to productivity, are composed of many workers, and face diminishing returns to labor given the wage paid to identical workers is the solution to the Stole-Zwiebel bilateral bargaining problem. Helpman and Iskhoki (2008) show that a unique single wage (degenerate) equilibrium solution to the model exists in this environment. In this paper, I demonstrate that another equilibrium exists that can be characterized by a non-degenerate distribution of wages in which more productive firms pay more if employed workers are able to search. Generically this dispersed wage equilibrium is unique and exists if and only if firms are heterogenous with respect to factor productivity. Finally, employment is lower in the dispersed wage equilibrium than in the single wage equilibrium but this fact does not imply that welfare is higher in the single wage equilibrium

Equilibrium labor turnover, firm growth and unemployment by Melvyn Glyn Coles( Book )

7 editions published in 2012 in English and held by 10 WorldCat member libraries worldwide

This paper identifies a data-consistent, equilibrium model of unemployment, wage dispersion, quit turnover and firm growth dynamics. In a separating equilibrium, more productive firms signal their type by paying strictly higher wages in every state of the market. Workers optimally quit to firms paying a higher wage and so move effciently from less to more productive firms. Start-up firms are initially small and grow endogenously over time. Consistent with Gibrat's law, individual firm growth rates depend on firm productivity but not on firm size. Aggregate unemployment evolves endogenously. Restrictions are identified so that the model is consistent with empirical wage distributions. -- Wage dispersion ; signalling ; labor turnover ; unemployment
Equilibrium wage and employment dynamics in a model of wage posting without commitment by Melvyn Glyn Coles( Book )

9 editions published in 2011 in English and German and held by 9 WorldCat member libraries worldwide

A rich but tractable variant of the Burdett-Mortensen model of wage setting behavior is formulated and a dynamic market equilibrium solution to the model is defined and characterized. In the model, firms cannot commit to wage contracts. Instead, the Markov perfect equilibrium to the wage setting game, characterized by Coles (2001), is assumed. In addition, firm recruiting decisions, firm entry and exit, and transitory firm productivity shocks are incorporated into the model. Given that the cost of recruiting workers is proportional to firm employment, we establish the existence of an equilibrium solution to the model in which wages are not contingent on firm size but more productive employers always pay higher wages. Although the state space, the distribution of workers over firms, is large in the general case, it reduces to a scalar that can be interpreted as the unemployment rate in the special case of homogenous firms. Furthermore, the equilibrium is unique. As the dimension of the state space is equal to the number of firms types in general, an (approximate) equilibrium is computable
Earnings, unemployment, and the allocation of time over time( )

1 edition published in 1984 in English and held by 3 WorldCat member libraries worldwide

A stochastic dynamic model of labour supply is specified and analysed empirically. The theoretical model provides a sound structural economic basis for a class of empirical models which have been shown useful. The implications of the estimated model are explored and diagnostic checks are suggested and implemented.--SCAD summary
