Imposing and testing curvature conditions on a Box-Cox function
Koebel, Bertrand M.; Falk, Martin; Laisney, François - 2000
We present a new method for imposing and testing concavity of a cost function using asymptotic least squares, which can easily be implemented even for cost functions which are nonlinear in parameters. We provide an illustration on the basis of a (generalized) Box-Cox cost function with six...

The effect of low-wage subsidies on skills and employment
Oskamp, Frank; Snower, Dennis J. - 2006
We explore the far-reaching implications of low-wage subsidies on aggregate employment. Low-wage subsidies have three important effects. First, they promote employment of unskilled workers (who tend to be the ones who earn low wages). Second, by raising the payoff of unskilled work relative to...

Alternative approaches to evaluation in empirical microeconomics
Blundell, Richard W.; Dias, Monica Costa - 2002
Four alternative but related approaches to empirical evaluation of policy interventions are studied: social experiments, natural experiments, matching methods, and instrumental variables. In each case the necessary assumptions and the data requirements are considered for estimation of a number...

An empirical investigation of labor income processes
Guvenen, Fatih - 2007

On the cyclicality of real wages and wage differentials
Otrok, Christopher; Pourpourides, Panayiotis M. - 2008
We show that two models of the labor market, a Walrasian model and a labor contracting model, both have an approximate dynamic factor structure. We use this result to motivate our empirical approach to estimating the cyclical properties of real wages, which does not impose any structure between...
