Wage formation is often analyzed by assuming that wage differentials reflect productivity differentials intrinsic to the workers, like differences in skill or qualification. Observed industry and firm effects on wages suggests, however, that wage differentials may result from causes rather...

This paper develops a theory of stagflation, based on turnover-efficiency-wage theory. In these theories, wages are forward-looking, i.e., set to keep incumbents with the firm. The employed workers apply for better jobs and compete with unemployed applicants. An employed applicant is, however,...

A labor market is considered that is characterized by job competition over job ladders. Firms paying more for comparable jobs can attract workers with better background characteristics (with general human capital) and will lose fewer trained workers (with general and firm-specific human...

A firm may reduce its turnover and the entailed turnover costs by raising wages. A rise in unemployment reduces turnover and turnover costs in a similar way. The interaction of these effects leads – in presence of perfectly flexible wages – to a stable equilibrium in the labor market which...

This papers describes an estimator for a standard state-space model with coefficients generated by a random walk that is statistically superior to the Kalman filter as applied to this particular class of models. Two closely related estimators for the variances are introduced: A maximum...

This note gives a fairly complete statistical description of the Hodrick-Prescott Filter (1997), originally proposed by Leser (1961). It builds on an approach to seasonal adjustment suggested by Leser (1963) and Schlicht (1981, 1984). A moments estimator for the smoothing parameter is proposed...

This note critically evaluates the New Classical Macroeconomics from a Marshallian perspective. Revisiting the famous Keynes-Tinbergen controversy, it is argued that Keynes' criticism comprises the "Lucas critique," and that it is misleading to label this a critique of Keynesian economics. The...

The estimation of models with time-varying coefficients is usually performed by Kalman-Bucy filtering. The two-sided filter proposed by Schlicht (1988) is statistically and computationally superior to the one-sided Kalman-Bucy filter. This paper describes the estimation procedure and the program...
