We develop a unified theory of endogenous business cycles in which expansions are neoclassical growth periods driven by productivity improvements and capital accumulation, while downturns are the result of Keynesian contractions in aggregate demand below potential output. Recessions allow...

We show how a Schumpeterian process of creative destruction can induce coordination in the timing of entrepreneurial activities across diverse sectors of the economy.Consequently, a multi-sector economy, in which sector-specific, productivity improvements are made by independent, profit-seeking...

The relative price of services rises with development. A standard interpretation of this fact is that cross-country productivity differences are larger in manufacturing than in services. The service sector comprises heterogeneous categories. We document that the behavior of relative prices is...

Sustained growth in emerging markets and developing economies requires long-term, reliable capital to finance productive investment, including in basic infrastructure. However, the availability and composition of long-term financing is constrained, partly due to fragile market conditions and...

Cities experience significant, near random walk productivity shocks, yet population is slow to adjust. In practise local population changes are dominated by variation in net migration, and we argue that understanding gross migration is essential to quantify how net migration may slow population...

There are striking differences in the size distribution of farms between rich and poor countries. We study the determinants of farm-size across countries and their impact on agricultural and aggregate productivity by developing a quantitative model of agriculture and non-agriculture that...

The prevalence of untitled land in poor countries helps explain the agricultural productivity gap between rich and poor countries. Since untitled land cannot be rented or traded across farmers, it creates not only land market misallocation, but also distortions in occupational choice. I build a...

Consensus forecasts for the global economy over the medium and long term predict the world's economic gravity will substantially shift towards Asia and especially towards the Asian Giants, China and India. While such forecasts may pan out, there are substantial reasons that China and India may...

No region of the United States fared worse over the postwar period than the "Rust Belt," the heavy manufacturing region bordering the Great Lakes. This paper hypothesizes that the Rust Belt declined in large part due to a lack of competitive pressure in its labor and output markets. We formalize...
