We consider a committee problem in which efficient information aggregation is hindered by differences in preferences. Sufficiently large delays could foster information aggregation but would require commitment. In a dynamic delay mechanism with limited commitment, successive rounds of decision-making are punctuated by delays that are uniformly bounded from above. Any optimal sequence of delays ...

A handful of developing countries have successfully built some of the necessary scientific, technological and industrial capacity to take advantage of the opportunities presented by biotechnology. The early enthusiasm and expectation that biotechnology will address some of the challenges of poor countries has not translated into the successful diffusion and use of the technology to meet the eco...

This paper is a partial review of the literature on ‘social preferences’. There are empirical findings that convincingly demonstrate the existence of social preferences, but there are also studies that indicate their fragility. So how robust are social preferences, and how exactly are they context dependent? One of the most promising insights from the literature, in my view, is an equilibrium e...

BACKGROUND Heat is recognized as one of the deadliest weather-related phenomena. Although the impact of high temperatures on mortality has been a subject of extensive research, few previous studies have assessed the impact of population adaptation to heat. METHODS We examined adaptation patterns by analyzing daily temperature and mortality data spanning more than a century in New York City. U...
