This paper examines the role of changes in sectoral productivity gaps over time in accounting for growth realized by countries over the past few decades. To quantify the productivity impact of the sectoral gaps, a simple model of resource allocation is developed in which the gaps arise due to...

Using panel data on input-output intensities and expenditure prices from 28 countries, this paper finds the elasticity of substitution across sectoral inputs to be less than one in each of the three broad sectors of the economy. Intermediates are most complementary in the production of services...

The paper uses a detailed household survey to document precautionary wealth accumulation in Afghanistan, with wealth being significantly higher for households facing higher income uncertainty. Annual household expenditure on nondurable goods is also lower for these households. There is no...

This article examines the accumulation of precautionary wealth in Afghanistan using detailed data from a large household survey. A percent increase in income variance is associated with a 0.22 and 0.84% increase in broad and narrow wealth, respectively. This precautionary response is most...
