Development accounting shows that a significant part of cross-country income differences is attributed to differences in total factor productivity (TFP), but the sources of TFP differences are not well understood. This paper considers the role of international trade to explain cross-country...

I review the literature on labor's share of national income in developed and developing countries. These shares have varied systematically over the post-World War II period, rising until the late 1970s and then falling until now. Explanations for the decline in labor's share include technical...

We develop a dynamic trade model to understand the effects on within-country inequality of trade in intermediates, also known as international unbundling of production. We consider a world economy where countries only differ in their productivity and consume final good varieties from all country...

We show that even in the absence of diminishing returns in production and technological spillovers, international trade leads to a stable world income distribution. This is because specialization and trade introduce de facto diminishing returns: Countries that accumulate capital faster than...

This paper develops a quantitative, multi-country model of endogenous growth, international trade, and international knowledge flows in order to understand how access to both foreign products and technologies, together, influences innovation incentives and the world distribution of income. An...

We use a dynamic trade model with two sectors and two types of workers to analyze the optimal setting of income-generating tariffs. This approach allows us to take account of adjustment dynamics, distributional aspects and the time horizon of policy makers and workers. In response to a...

Since 1980, there has been a steady increase in earnings inequality alongside rapid technological growth in the U.S. economy. To what extent does technological change explain the observed increase in earnings dispersion? How does it affect the optimal progressivity of the tax system? To answer...

We analyze the effects of automation and education on economic growth and inequality in an R&D-based growth model with two types of labor: high-skilled labor that is complementary to machines and low-skilled labor that is a substitute for machines. The model predicts that innovation-driven...

The authors study the sources and pattern of China's impressive economic growth over the past 25 years and show that key issues currently of concern to policymakers - widening inequality, rural poverty, and resource intensity - are to a large extent rooted in China's growth strategy, and...
