Bioeconomics: two examples
Bioeconomic describes the research program that aims at laying the foundation of the analysis of economic and strategic behavior on its biological foundation. Bioeconomics takes seriously the hypothesis that human economic behavior is biologically based: to the first order approximation, institutions are downstream from politics, politics is downstream from culture, culture is downstream from biology. In the talk I will present two papers illustrating the concept in action.
In the first and second paper I describe how a foundation of stochastic choice on the process determining choice allows us to obtain a precise characterization of individual characteristics producing the choices; not just the economic characteristics (for example, the discount factor in a delayed payments choice task) but also the care and skill used in choice.
In the third paper I describe how we can now link educational and economic success, and hence the analysis of intergenerational mobility and inequality, to the genotype of the individuals, and identify the pathways of the effects. The theory is based on classical models of parental investment, extended to consider the genetic profile of the population.

The Crucial Role of International Trade in Adaptation to Climate Change
Climate change effects on agricultural yields will be uneven over the world with a few countries, mostly in high latitudes, that may experience gains, while most will see average yield decrease. This paper aims at quantifying the role of international trade in attenuating the effects of climate change by allowing the expression of the new climate-induced pattern of comparative advantages. To do this, we develop a quantitative general equilibrium trade model where the representation of acreage and land use choices is inspired from modern Ricardian trade models but also consistent with theoretical and empirical literature on land use choices. The model is calibrated on spatially explicit information about potential yields before and after climate change coming from the agronomic literature. The results show that the climate-induced yield changes generate large price movements that incentivize adjustments in acreage and trade. The new trade pattern is very different from the current one showing the important role of trade flows in adapting to climate change. This is confirmed by large increased welfare losses from climate change when adjustments in trade flows are constrained.
