This study disentangles experimentally imitation, reinforcement, and reciprocity in repeated prisoners' dilemmas. We compare a simple situation in which players interact only with their neighbours (local interaction) with one where players interact with all members of the population (group...

The paper focuses on the prospects interaction economics opens in the economic geography field. The first part is devoted to the conditions in which interaction economics emerges and develops. The second one focuses on the main concepts and models. In the third one, we show through a recent...

In this paper we study learning and cooperation in repeated prisoners' dilemmas experiments. We compare interaction neighbourhoods of different sizes and structure and we observe choices under different information conditions and estimate parameters of a learning model. We test robustness of the...

Higher ability workers benefit more from bigger cities while housing costs there are higher for everyone, and yet there is little sorting on ability. A possible explanation is that young individuals have an imperfect assessment of their ability, and, when they learn about it, early decisions...

Biofuel production has recently attracted a great deal of attention. Some anticipate substantial social and environmental benefits, while at the same time expecting sound profitability for investors. Others are more doubtful, envisaging large trade-offs between the pursuit of social,...

If mental maps are a well-known subject in spatial analysis, they suffer from the difficulties to make them an operational concept. Nowadays, the development of cognitive science opens up new perspectives. Thanks to an association of spatial economists, roboticists and computer scientists in the...

Individual earnings are higher in bigger cities. We consider three reasons: spatial sorting of initially more productive workers, static advantages associated with workers' current location, and learning by working in big cities. Using rich administrative data for Spain, we find that workers in...

I demonstrate a straightforward but apparently widely unrecognized implication of the standard requirements for perfect competition: an economy in which consumers can choose to learn is generally not perfectly competitive. In particular, if endogenous welfare relevant learning is feasible, the...
