The construction sector plays a key role in providing structures for economies. This paper surveys the literature on key issues pertaining to the construction sector. It starts by summarizing our knowledge about differences in unit costs across time and space. It then discusses key bottlenecks...

This paper asks whether increasing productivity in the electricity sector can yield larger long-run GDP gains than suggested by electricity's small share of aggregate economic activity. We answer this question using a dynamic model in which electricity is a strong complement to other inputs in...

Why are average hours worked per adult lower in rich countries than in poor countries? We consider two natural explanations: income effects in preferences, in which leisure becomes more valuable when income rises, and distortionary tax systems, which are more prevalent in richer countries. To...

Why are average hours worked per adult lower in rich countries than in poor countries? We consider two natural explanations: income effects in preferences, in which leisure becomes more valuable when income rises, and distortionary tax systems, which are more prevalent in richer countries. To...

Many policymakers view power outages as a major constraint on firm productivity in developing countries. Yet empirical studies find modest short-run effects of outages on firm performance. This paper builds a dynamic macroeconomic model to study the long-run general-equilibrium effects of power...

How do average hours worked vary across the world income distribution? To answer this question, we build a new internationally comparable database of hours worked covering countries of all income levels. We document that average hours worked per adult are substantially higher in low-income...

Inflation is often assumed to affect all people in the same way. In practice, differences in spending patterns across households and differences in price increases across goods and services lead to unequal levels of inflation for different households. In this paper, we measure the degree of...

This paper draws on household survey data from countries of all income levels to measure how average unemployment rates vary with income per capita. We document that unemployment is increasing with GDP per capita. Furthermore, we show that this fact is accounted for almost entirely by...

This paper explores the extent to which migration-related capital flows can explain the variation in investment rates and current and capital account imbalances across OECD countries. Migrants must be equipped with machines, and the resulting demands for capital are likely, all else being equal,...

Across countries, women and men allocate time differently between market work, domestic services, and care work. In this paper, we document the gender division of work, drawing on a new harmonized data set that provides us with high-quality time use data for 50 countries spanning the global...
