This study revisits the problem of the tragedy of the commons. Extracting agents participate in an evolutionary game in a complex social network and are subject to social pressure if they do not comply with the social norms. Social pressure depends on the dynamics of the resource, the network...

We study cooperation and group pressure in social networks by introducing a new concept termed moral ties. By combining network characteristics and agents’ actions, moral ties extend and refine the concept of social ties as a driver for group pressure. Direct moral ties depend on the size of...

This paper analyzes the influence that social networks and the state of a public good or common property resource have on compliance with social norms in relation to a social dilemma. We find that equilibria where compliers and defectors coexist (partial cooperation) can be stable and are...

El Manejo Forestal Sostenible (MFS) es un instrumento de gestión forestal basado en un proceso de planificación racional sobre la oferta forestal y las normas y prescripciones de protección y sostenibilidad de los bosques naturales. En Colombia se ha identificado como una estrategia para...

This paper analyses smallholder farmers’ willingness to participate in crop insurance programs, using recent data from cocoa farmers in Ghana. Given the significance of output uncertainty and imperfect capital and insurance markets, we develop a theoretical framework to analyse how risk and...

Different regulatory bodies tend to develop environmental policies not recognizing the interdependencies between externalities. For example, one authority may regulate a stock pollution and another a flow pollution that result from the same activity. This study introduces a two-phase...

This article develops a theoretical framework to examine the relationship between land tenure agreements and households’ investment in land improvement and conservation measures. It then analyzes this relationship with a multivariate probit model based on a survey data from a sample of 560...
