This paper explores the theoretical channels by which financial crises might have an impact on long-run growth. By exploiting occasionally binding financial constraints, we produce a model that generates endogenous crisis episodes featuring permanent falls in productivity, without generating...

Skill-biased technical change has occupied empirical economists for much of the 90s. However, the empirical literature has not progressed much beyond observing a positive correlation between technology indicators and demand shifts. Two hypotheses on the root causes of skill biases in technical...

The paper develops the Basic Climate Economic (BCE) model featuring the core elements of climate economics and climate policy. The BCE model incorporates fossil stock depletion, pollution stock accumulation, endogenous growth, and climate-induced capital depreciation. We first use graphical...

The world is banking on a major increase in food production, if the dietary needs and food preferences of an increasing, and increasingly rich, population are to be met. This requires the further expansion of modern agriculture, but modern agriculture rests on a small number of highly productive...

Services, which are less traded than goods, rose from 50 percent of world expenditure in 1970 to 80 percent in 2015. Such structural change restrained "openness"—the ratio of world trade to world GDP—over this period. We quantify this with a general equilibrium trade model...

Services, which are less traded than goods, rose from 58 percent of world expenditure in 1970 to 79 percent in 2015. In a trade model featuring nonhomothetic preferences and input-output linkages, we find that such structural change has restrained the growth in world trade to GDP by 16...

Services, which are less traded than goods, rose from 58 percent of world expenditure in 1970 to 79 percent in 2015. Using a Ricardian trade model incorporating endogenous structural change, we quantify how this substantial shift in consumption has affected trade. Without structural change, we...
