This paper proposes a novel instrumental variable method for program evaluation that only requires a single cross-section of data on the spatial intensity of programs and outcomes. The instruments are derived from a simple theoretical model of government decision-making in which governments are...

In this paper, we investigate the use of interactive effect or linear factor models in regional policy evaluation. We contrast treatment effect estimates obtained by Bai (2009)'s least squares method with the popular difference in difference estimates as well as with estimates obtained using...

This paper studies the social desirability of agglomeration and the efficiency arguments for policy intervention in a simple, analytically solvable 'new economic geography' model with two trade integrating regions. The location pattern emerging as market equilibrium is bubbleshapedʺ, i.e. it...

Does economic development have an unavoidable ecological cost? We examine the ecological impacts of one of India's signature place-based economic policies involving massive tax benefits for new industrial and infrastructure development following the creation of the new state of Uttarakhand. The...
