This paper describes a moments estimator for a standard state-space model with coefficients generated by a random walk. A penalized least squares estimation is linked to the GLS (Aitken) estimates of the corresponding linear model with time-invariant parameters. The VC estimates are moments...

Most demand - especially labor demand - is derived from the demand for some other product. This note demonstrates that the usual analysis of economic rent, as typically explained for the case of consumers' surplus, carries over to the case of derived demand

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...

Internal organization relies heavily on psychological consistency requirements. This thought has been emphasized in modern compensation theory, but has not been extended to organization theory. The perspective sheds new light on several topics in the theory of the firm, like the boundaries of...

Offering higher wages may enable firms to attract more applicants and screen them more carefully. If firms compete in this way in the labor market, "selection wages" emerge. This note illustrates this wage-setting mechanism. Selection wages may engender unconventional results, such as a pre-tax...
