Although the market for Canadian paintings is now of substantial magnitude, with several works having recently sold for well over a million dollars, it remains true that with very few exceptions, the works of Canadian painters are bought and sold only in Canada and held only by Canadian...

Local interactions refer to social and economic phenomena where individuals' choices are influenced by the choices of others who are `close' to them socially or geographically. This represents a fairly accurate picture of human experience. Furthermore, since local interactions imply particular...

We provide the first empirical application of a new approach proposed by Lee (2007) to estimate peer effects in a linear-in-means model. This approach allows to control for group-level unobservables and to solve the reflection problem. We investigate peer effects in student achievement in...

This paper examines the role of herd behavior (mimetism) and network effects as determinants of bilateral migration flows to thirteen of the EU-15 countries. Using an adapted gravity model controlling for economic activity, welfare progressivity, geospatial, and historic relationships, the...

The paper extends the standard tax evasion model by allowing for social interactions. In Manski's (1993) nomenclature, our model takes into account social conformity effects (i.e., endogenous interactions), fairness effects (i.e., exogenous interactions) and sorting effects (i.e., correlated...

This paper addresses the effects of peer pressure in work teams. Many empirical studies have shed light on the efficiency of peer pressure. Peer pressure can be defined as mechanisms of mutual monitoring and sanction established within a group of agents by the agents themselves in order to...

Agents face an ambiguous risk of biodiversity survival as well as ambiguous expected losses from its extinction. As a collectivity, agents are faced with the option of privately funding the protection of biodiversity for biomedical research. We propose two evolutionary models of threshold public...

This paper explores methodological issues surrounding the use of discrete choice experiments to elicit values for public goods. We develop an explicit game-theoretic model of individual decisions to a series of choice sets, providing general conditions under which surveys with repeated binary...

In a public-good experiment with heterogeneous endowments, we investigate if and how the contribution level as well as the previously observed fair-share rule of equal contributions relative to one's endowment (Hofmeyr et al., 2007; Keser et al., 2014) may be influenced by minimum-contribution...

We develop a model that accounts for the decay of the average contribution observed in experiments on voluntary contributions to a public good. The novel idea is that people's moral motivation is "weak"". Their judgment about the right contribution depends on observed contributions by group...
