This research provides an economic model of the way people behave during an IQ test. We distinguish a technology that describes how time investment improves performance from preferences that determine how much time people invest in each question. We disentangle these two elements empirically...

This paper demonstrates gender differences in risk aversion and ambiguity aversion. It also contributes to a growing literature relating economic preference parameters to psychological measures by asking whether variations in preference parameters among persons, and in particular across genders,...

This paper offers a model to explain how computer technology has changed the labor market. It demonstrates that wage differentials between computer users and non-users are consistent with the fact that computers are first introduced in high-wage jobs because of cost efficiency. Furthermore,...

When workers adopt technology at the point where the costs equal the increased productivity, output per worker increases immediately, while the productivity benefits increase only gradually if the costs continue to fall. As a result, workers in computer-adopting labor market groups experience an...

Despite indications that interpersonal interactions are important for understanding individual labor-market outcomes and have become more important over the last decades, there is little analysis by economists. This paper shows that interpersonal interactions are important determinants of...

Using data from the 1997 Skills Survey of the Employed British Workforce, we examine the returns to computer skills in Britain. Many researchers, using information on computer use, have concluded that wage differentials between computer users and non-users might, among others, be due to...

The large increase in computer use has raised the question whether people have to be taught computer skills before entering the labour market. Using data from the 1997 Skills Survey of the Employed British Workforce, we argue that neither the increase in computer use nor the fact that...

The model developed in this paper explains differences in the division of labour across firms as a result of computer technology adoption. We find that changes in the division of labour can result both from reduced production time and from improved communication possibilities. The first shifts...

This research develops a theory and presents empirical evidence of a link between economic outcomes and genetic evolution. Important properties for successful analysis of such a link are found in the adaptive immune system and particularly in the major histocompatibility complex (MHC), a...

This paper develops a framework to understand the role of interpersonal interactions in the labor market including task assignment and wages. Effective interpersonal interactions involve caring, to establish cooperation, and at the same time directness, to communicate in an unambiguous way. The...
