In 2009 and 2010, China undertook a 4 trillion Yuan fiscal stimulus, roughly equivalent to 12 percent of annual GDP. The "fiscal" stimulus was largely financed by off-balance sheet companies (local financing vehicles) that borrowed and spent on behalf of local governments. The off-balance sheet...

Starting in the late 1990s, China undertook a dramatic transformation of the large number of firms under state control. Small state-owned firms were privatized or closed. Large state-owned firms were corporatized and merged into large industrial groups under the control of the Chinese state. The...

We show that stricter bank liquidity standards can trigger unintended credit booms when there is heterogeneity in interbank pricing power. Attempts to circumvent the regulation change the allocation of savings across institutions, eliciting strategic responses that also change the allocation of...

China's investment rate is one of the highest in the world, which naturally leads one to suspect that the return to capital in China must be quite low. Using the data from China's national accounts, we estimate the rate of return to capital in China. We find that the aggregate rate of return to...

South Korea publicly disclosed detailed location information of individuals that tested positive for COVID-19. We quantify the effect of public disclosure on the transmission of the virus and economic losses in Seoul. The change in commuting patterns due to public disclosure lowers the number of...

The rise in national industry concentration in the US between 1977 and 2013 is driven by a new industrial revolution in three broad non-traded sectors: services, retail, and wholesale. Sectors where national concentration is rising have increased their share of employment, and the expansion is...

Entrants and incumbents can create new products and displace the products of competitors. Incumbents can also improve their existing products. How much of aggregate productivity growth occurs through each of these channels? Using data from the U.S. Longitudinal Business Database on all nonfarm...

We quantify the amount of spatial misallocation of labor across US cities and its aggregate costs. Misallocation arises because high productivity cities like New York and the San Francisco Bay Area have adopted stringent restrictions to new housing supply, effectively limiting the number of...

We propose a new sufficient statistic to measure the gains from trade in models where the extensive margin trade elasticity is not necessarily constant. This statistic is a function of one data moment, the market share of continuing domestic products, and one parameter, the elasticity of...

Resource misallocation can lower aggregate total factor productivity (TFP). We use micro data on manufacturing establishments to quantify the potential extent of misallocation in China and India compared to the U.S. Compared to the U.S., we measure sizable gaps in marginal products of labor and...
