Simple majority does not reflect the intensity of voters’ preferences. This paper presents an efficient collective choice mechanism when the choice is binary and the designer may use non-trasferable punishments to persuade agents to reveal their private information. The designer faces a...

A skill-biased change in technology can account at once for the changes observed in a number of important variables of the US labour market between 1970 and 1990. These include the increasing inequality in wages, both between and within education groups, and the increase in unemployment at all...

Does innovation boost or fall with more competition when innovation follows a memory process? This paper provides a theoretical model which analyzes the innovation and competition relationship assuming that innovation follows a short-memory process. I find innovation increases with more product...

We consider the issue of illegal migration from Mexico to the US, and examine whether the lack of legal status causally impacts on outcomes, specifically wages and remitting behavior. These outcomes are of particular interest given the extent of legal and illegal migration, and the resulting...

This paper explores the main determinants of productivity growth. The analysis is performed using Spanish firm-level data. We define a framework where the relative magnitudes of alternative, but not exclusive, sources of technical change is simultaneously estimated. Our main finding is that...

This paper proposes and implements a new method of measuring the degree of consumption smoothing using data from the Consumer Expenditure Survey. The structure of this Survey is such that estimators previously used in the literature are inconsistent, simply because income is measured annually...

This paper considers the place of mathematical methods based on probability in the work of the London (later Royal) Statistical Society in the half-century 1883-1933. The end-points are chosen because mathematical work started to appear regularly in 1883 and 1933 saw the formation of the...

General equilibrium models in which compensation for local amenities occurs in both housing and labour markets have been widely used to generate implicit amenity prices and regional quality of life indices. An implication and prospective test of such models is that individuals who are outside...

The South Sea Bubble of 1720 is often cited as an example of a fraud. It is often stated that the South Sea Company had not interest in, or aptitude for, the slave trade. It had been granted the monopoly right to ship slaves to the Spanish-held Americas. This paper uses shipping data to show...

This paper investigates the impact of contemporary flows of immigrants on internal movements of natives and earlier immigrants across the local authorities of England and Wales. To analyse the impact of immigration, a theoretical framework where natives and immigrants are imperfect substitutes...
