This paper provides estimates of the union wage gap in Portugal, a nation until recently lacking independent data on union density at firm level. Having estimated nonlinear and linear estimates of the effect of union density on the wage gap, the next stage of the analysis seeks to account for...

Severance pay, a fixed-sum payment to workers at job separation, has been the focus of intense policy concern for the last several decades, but much of this concern is unearned. The design of the ideal separation package is outlined and severance pay emerges as a natural component of job...

We build a model of worker interdependence in which two workers can either compete or cooperate and compare performance under either scenario to that of a single worker working in isolation. We show that whilst competition unequivocally reduces performance, cooperation may raise or lower...

We present a wage-hours contract designed to minimize costly job turnover given investments in on the job training combined with firm and worker information asymmetries. It may be optimal for the parties to work 'long hours' remunerated at premium rates for guaranteed overtime hours. Based on...

We study how help can be fostered by means of a team bonus in the presence of rank-order tournaments. In a simple model we combine elements of relative rewards and a team bonus and study their effect on effort, help and sabotage. Quite intuitively the theoretical analysis suggests that team...

This paper tests two hypotheses from the theory of elimination tournaments: (i) that uneven tournaments, where the contestants are ex ante heterogeneous, entail lower effort exertion; this is a prediction from agency theory that has not been tested empirically before; and (ii) whether incentives...

This study uses panel data describing about 6,500 employees in a large international company to study the incentive effects of performance related pay. The company uses two performance related remuneration mechanisms. One is an individual "surprise" bonus payment. The other is a more structured...

Tournament incentive schemes offer payments dependent on relative performance and thereby are intended to motivate agents to exert productive effort. Unfortunately, however, an agent may also be tempted to destroy the production of his competitors in order to improve the own relative position....

We investigate wage-hours contracts within a four-period rent sharing model that incorporates asymmetric information. Distinctions are made among (a) an investment period, (b) a period in which the parties may separate (quits or layoffs) or continue rent accumulation and sharing, (c) a post...

We develop a rationale for the payment by firms of a wage premium on marginal, or overtime, weekly hours. We examine wage-hours contracts within the framework of a two-period specific human capital model with asymmetric information. The wage premium serves to achieve contract efficiency. For...
