Estimating a dynamic equilibrium model of firm location choices in an urban economy
We develop a new dynamic general equilibrium model to explain firm entry, exit, and relocation decisions in an urban economy with multiple locations and agglomeration externalities. We characterize the stationary distribution of firms that arises in equilibrium. We estimate the parameters of the model using a method of moments estimator. Using unique panel data collected by Dun and Bradstreet, we find that our model fits the moments used in estimation as well as a set of moments that we use for model validation. Agglomeration externalities increase the productivity of firms by about 8 ...
The Political Economy of Underfunded Municipal Pension
This paper analyzes the determinants of underfunding of local government?s pension funds using a politico-economic overlapping generations model. We show that a binding down payment constraint in the housing market dampens capitalization of future taxes into current land prices. Thus, a local government?s pension funding policy matters for land prices and the utility of young households. Underfunding arises in equilibrium if the pension funding policy is set by the old generation. Young households instead favor a policy of full funding. Empirical results based on cross-city comparisons in the ...
