Purpose: Ever since Portugal joined the European Union, Portuguese organisations have been struggling with both the challenges of new competitors flooding in from other European countries and taking advantage of the opportunities the new enlarged integrated market offered them. This is because...

Knowledge of the marginal productivity of water is crucial for decisions about its allocation between uses, which is particularly important in the context of increasing competition for water. Using primary, plot-level panel data, this article estimates the marginal productivity of water from...

Climate change is widely expected to lead to changing rainfall variability and thus to changing frequency of drought. In places where drought is a major driver of agroecosystem dynamics, as in the extensive livestock grazing systems that dominate Africa's sprawling arid and semi-arid lands,...

The implementation of REDD+ requires knowledge of the willingness to accept land use change contracts and its application over large areas. This paper uses primary data from Indonesia to contrast two approaches to the elicitation of the supply curve for carbon: an auction and an analysis of...

We use a large, rich dataset compiled from results of university extension trials to estimate the contribution of genetic modification (GM) to changes in corn yield in the United States from timeA to timeB. Through repeated experimental trials, we obtain consistent estimates of the effect of...

This paper explores the consequences of nonlinear wealth dynamics for the formation of bilateral credit arrangements to help manage idiosyncratic risk. Using original data on expected wealth dynamics, social networks and informal loans among southern Ethiopian pastoralist households, we find...

Although there is a considerable amount of empirical evidence on inter-firm collaborations within technology-based industries, there are only a few works focussing on R&D cooperation by low-tech firms, especially small and medium-sized enterprises (SMEs). Providing further and new evidence based...

Summary This paper examines how farmers in a developing country search for information. Using data on farmers' decisions to connect with other farmers in order to ask for information about different agricultural problems, we explore the role played by identity in accessing information. We show...
