One of the main drawbacks of current methods to measure market integration is the assumption of constant transaction costs. In this paper, we propose a non-parametric extension to the commonly used threshold models, allowing us to estimate transaction costs in a more flexible way. We illustrate...

Africa’s recent economic growth is at a historical high, the patterns associated with this growth appear to be quite different from the Asian experiences where rapid growth was fueled by labor intensive, export-oriented manufacturing. Because this pattern differs with our typical view of...

The world’s population is expected to reach 9 billion by 2050. Climate change, population, and income growth will drive food demand in the coming decades. Baseline scenarios show food prices for maize, rice, and wheat would significantly increase between 2005 and 2050, and the number of...

In this paper, we examine the implications of alternative country-specific scenarios for biofortification on the reduction of micronutrient deficiency prevalence in under-fives. The scenarios are implemented within a long-term projections model of agriculture production and consumption, given...

This paper provides a comprehensive analysis of the degree of co-movement among the nominal price returns of 11 major energy, agricultural, and food commodities using monthly data between 1970 and 2013. The authors study the extent and the time evolution of unconditional and conditional...

Bioeconomic models can provide powerful insights into the interactions between people and the natural ecosystems on which they depend. For example, bioeconomic models of fisheries have long been used to provide early warnings about the sustainability of harvest levels or the impacts of new...
