|January 2020||Linguistic Traits and Human Capital Formation|
with Oded Galor, Assaf Sarid: w26699
This research establishes the influence of linguistic traits on human behavior. Exploiting variations in the languages spoken by children of migrants with identical ancestral countries of origin, the analysis indicates that the presence of periphrastic future tense, and its association with long-term orientation has a significant positive impact on educational attainment, whereas the presence of sex-based grammatical gender, and its association with gender bias, has a significant adverse impact on female educational attainment.

|November 2018||Geographical Roots of the Coevolution of Cultural and Linguistic Traits|
with Oded Galor, Assaf Sarid: w25289
This research explores the geographical origins of the coevolution of cultural and linguistic traits in the course of human history, relating the geographical roots of long-term orientation to the structure of the future tense, the agricultural determinants of gender bias to the presence of sex-based grammatical gender, and the ecological origins of hierarchical orientation to the existence of politeness distinctions. The study advances the hypothesis and establishes empirically that: (i) geographical characteristics that were conducive to higher natural return to agricultural investment contributed to the existing cross-language variations in the structure of the future tense, (ii) the agricultural determinants of gender gap in agricultural productivity fostered the existence of sex-based...
|August 2014||The Agricultural Origins of Time Preference|
with Oded Galor: w20438
This research explores the origins of the distribution of time preference across regions. It advances the hypothesis, and establishes empirically, that geographical variations in natural land productivity and their impact on the return to agricultural investment have had a persistent effect on the distribution of long-term orientation across societies. In particular, exploiting a natural experiment associated with the expansion of suitable crops for cultivation in the course of the Columbian Exchange, the research establishes that agro-climatic characteristics in the pre-industrial era that were conducive to higher return to agricultural investment, triggered selection and learning processes that had a persistent positive effect on the prevalence of long-term orientation in the contemporar...

|October 2009||Adaptive Consumption Behavior|
with Peter Howitt: w15427
This paper proposes and studies a theory of adaptive consumption behavior under income uncertainty and liquidity constraints. We assume that consumption is governed by a linear function of wealth, whose coefficients are revised each period by a procedure, which, although sophisticated, places few informational or computational demands on the consumer. We show that under a variety of settings, our procedure converges quickly to a set of coefficients with low welfare cost relative to a fully optimal nonlinear consumption function.
