Laboratory experiments are a widely used methodology for advancing causal knowledge in the physical and life sciences. With the exception of psychology, the adoption of laboratory experiments has been much slower in the social sciences, although during the last two decades, the use of lab...

This paper presents new evidence on the distribution of risk attitudes in the population, using a novel set of survey questions and a representative sample of roughly 22,000 individuals living in Germany. Using a question that asks about willingness to take risks in general, on an 11-point...

We discuss the contribution of the experimental literature to the understanding of both traditional and previously unexplored dimensions of gender differences and discuss their bearings on labor market outcomes. Experiments have offered new findings on gender discrimination, and while they have...

We seed noisy information to members of a real-world social network to study how information diffusion and information aggregation jointly shape social learning. Our environment features substantial social learning. We show that learning occurs via diffusion which is highly imperfect: signals...

It is most important to get the conceptual aspects of a problem clear, before starting any formal or statistical analysis. This the author has always tried to do.

This paper examines the business cycle properties of a small set of real US macroeconomic time series using a variety of detrending methods. It is shown: (i) that both quantitatively and qualitatively `stylized facts' of US business cycles vary widely across detrending methods; (ii) that...

Bob Gregory contrasts ‘the presuppositions of Royal Parade’ of 1950 Melbourne with the present outlook of himself and Australia at large. He outlines the evolution of his methodological position from the University of Melbourne student to the Canberra policy advisor, and defends that...

This Paper is an exercise in dating the euro area business cycle on a monthly basis. We construct several monthly European real GDP series, and then apply the Bry-Boschan (1971) procedure. Using this method we identify four business cycles. Studying further indicators of business activity, we...

We study the effects of German unification on macroeconomic variables in a model with capital accumulation, skill differences and a welfare state. The integration of two economies differing in capital holdings and skill distribution is similar to a mass migration of low-skilled agents holding no...
