This paper investigates the nature of U.S. fiscal policy in the aftermath of 9/11. We argue that the recent dramatic fall in the government surplus and the large fall in tax rates cannot be accounted for by either the state of the U.S. economy as of 9/11 or as the typical response of fiscal...

Cities exist because of the productivity gains arising from clustering production and workers, a process called agglomeration. How important is agglomeration for aggregate growth? This paper constructs a dynamic stochastic general equilibrium model of cities and uses it to estimate the effect of...

This paper builds a dynamic general equilibrium model of cities and uses it to analyze the role of local housing markets and moving costs in determining the character and extent of labor reallocation in the US economy. Labor reallocation in the model is driven by idiosyncratic city-specific...

Infrastructure capital, the structures and equipment that comprise "the basic systems that bridge distance and bring productive inputs together" (Cisneros 2010), is a vital input into the productive capacity of any economy. It is often claimed that the US fails to invest sufficiently in its own...

steep decline in residential investment since 2005.

Cities experience significant, near random walk productivity shocks, yet population is slow to adjust. In practice 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...

This paper investigates the response of hours worked and real wages to fiscal policy shocks in the U.S. during the post World War II era. We identify these shocks with exogenous changes in military purchases and argue that they lead to a persistent increase in government purchases and tax rates...

Residential investment before the mid 1980s was very volatile and since then it has been much less volatile. Before the 1980s mortgage markets were highly regulated and mortgage opportunities were limited, while large numbers of baby-boom households were acquiring their first house. Since 1980...
