We exploit regional variation in suitability for cultivating potatoes, together with time variation arising from their introduction to the Old World from the Americas, to estimate the impact of potatoes on Old World population and urbanization. Our results show that the introduction of the...

Building on evidence from neurobiology and neuroscience, we model the physiological limitations faced by individuals in the process of decision-making that starts with sensory perception and ends in action selection. The brain sets a neuronal threshold, observes whether the neuronal cell firing...

This paper proposes a rule to determine the winner of a soccer match which is different from the traditional penalty shoot-outs at the end of extra time. We show that games can be more attractive if penalties are shot before extra time and the outcome counts only if the tie is preserved during...

We model the brain as a multi-agent organization. Based on recent neuroscience evidence, we assume that different systems of the brain have different time-horizons and different access to information. Introducing asymmetric information as a restriction on optimal choices generates endogenous...

Gender-based discrimination is a pervasive and costly phenomenon. To a greater or lesser extent, all economies present a gender wage gap, associated with lower female labour force participation rates and higher fertility. This paper presents a growth model where saving, fertility and labour...

This paper derives the conditions under which fitness-reducing alleles can survive in a long-run stationary equilibrium for a trading population, extending the results in Saint-Paul (2002) for arbitrary systems of sexual reproduction.

This paper documents a stylized fact not well appreciated in the literature. The Third World has been undergoing an emigration life cycle since the 1960s, and, except for Africa, emigration rates have been level or even declining since a peak in the late 1980s the early 1990s. The current...

We construct a structural model of household decision-making and matching and estimate the returns to schooling within marriage. We consider agents with idiosyn- cratic preferences for marriage that may be correlated with education, and we allow the education levels of spouses to interact in...

This paper studies the impact of permanent and transitory shocks to income on parental investments in children. We use panel data on family income, and an index of investments in children in time and goods, from the Children of the National Longitudinal Survey of Youth. Consistent with the...

Though the real exchange rate is a key price for most economies, our understanding of its determinants is still incomplete. This paper studies the implications of status competition in the marriage market for the real exchange rate. In theory, a rise in the sex ratio (increasing relative surplus...
