Research Waves
écrit avec Gilat Levy (London School of Economics) and Ronny Razin (Ronny Razin)
We study a continuous-time setting in which researchers irreversibly choose between two risky fields of exploration and their individual time of entry. Information production in each field depends on the mass of researchers who have already joined that field.
In the bad news case, where a unique 'bandwagon' equilibrium wave emerges, we show that as the priors of the two fields are further apart, the equilibrium wave starts earlier, and it is slower and longer. On the other hand, the good news case is characterized by two sequential fast surges into the two fields. The probability of both fields being explored depends on the researchers' pool size and the efficacy of the information production technology.
We compare the equilibrium outcomes to a welfare benchmark that accounts for the societal externalities of research and discuss how alternative incentive structures (such as citations' impact and tenure clock) affect the researchers' specialization decisions.

Zero-Sum Thinking and the Roots of US Political Differences
We investigate the origins and implications of zero-sum thinking – the belief that gains for one individual or group tend to come at the cost of others. Using a new survey of a sample of 20,400 U.S. residents, we measure zero-sum thinking, political preferences, policy views, and a rich array of ancestral information spanning four generations. We find that a more zero-sum mindset is strongly associated with more support for government redistribution, race- and gender-based affirmative action, and more restrictive immigration policies. Zero-sum thinking can be traced back to the experiences of both the individual and their ancestors, encompassing factors such as the degree of intergenerational upward mobility they experienced, whether they immigrated to the United States or lived in a location with more immigrants, and whether they were enslaved or lived in a location with more enslavement

*Local Extreme Climate Events and Public Budgets
Local government action is crucial for mitigating and adapting to the effects of the ongoing climate crisis. This paper analyses the impact of extreme climate events on subnational public spending and revenue allocation in Spain from 2010 to 2021. To this end, I combine municipal-level budgets with measures of drought severity and heat waves and rely on the plausibly exogenous nature of these shocks for identification. I find small positive effects of high temperatures on public service provision expenditure, with some evidence of adaptation. Similarly, an event study approach shows that there are increases in water provision expenditure in the years after a severe drought.
