Using the mass closure of development zones in 2004 as a natural experiment, we examine the causal effect of development zones on firm level TFP in China. The difference-in-difference estimator shows that on average, loss of development zone policies results in 6.5% loss of firms' TFP....

Many studies of regional disparity in China have focused on the preferential policies received by the coastal provinces. We decomposed the location dummies in provincial growth regressions to obtain estimates of the effects of geography and policy on provincial growth rates in 1996-99. Their...

We study optimal spatial policies in quantitative trade and geography frameworks with spillovers and sorting of heterogeneous workers. We characterize the spatial transfers that must hold in efficient allocations, as well as labor subsidies that would implement them. Assuming homogeneous workers...

In many cities, restaurants and retail establishments are spatially concentrated. Economists have long recognized the presence of demand externalities that arise from spatial agglomeration as a possible explanation, but empirically identifying this type of spillovers has proven difficult. We...

We document that individuals who grew up in areas with high density of firms are more likely, as adults, to become entrepreneurs, controlling for the density of firms in their current location. Conditional on becoming entrepreneurs, the same individuals are also more likely to be successful...

We study the consequences of month-end lending incentives for Chinese bank managers. Using data from two banks, one state-owned and the other partially privatized, we show a clear increase in lending in the final days of each month, a result of both more loan issuance and higher value per loan....

In developing countries, informal firms (those that are not registered with the government) account for about half of all economic activity. We consider three broad views of the role of such firms in economic development. According to the romantic view, these firms would become the engine of...

This paper investigates the determinants of informal economic activity. We present two equilibrium models of informality and test their implications using a survey of 48,000+ small firms in Brazil. We define informality as tax avoidance; firms in the informal sector avoid tax payments but suffer...
