Skill-biased technical change is usually interpreted in terms of the efficiency parameters ofskilled and unskilled labor. This implies that the relative productivity of skilled workerschanges proportionally in all tasks. In contrast, we argue that technical changes also affectthe curvature of...

Survey studies on exchange rate expectations tend to reject the rational expectations hypothesis for longer horizons. Extrapolative, adaptive and regressive expectations have been tested as alternatives, usually rejecting static expectations. The purpose of this paper is to investigate the...

Empirical studies reject uncovered interest parity. Experimental and survey data studies reject rational expectations and find evidence of adaptive, regressive, bandwagon and distributed lag expectations. In this paper we investigate how these two findings are related. We show that uncovered...
