|Spillover Effects of IP Protection in the Inter-war Aircraft Industry|
with : w26490
Can granting IP protection to producers of one good affect the innovation rate in other related goods? To answer this question we exploit a unique policy experiment in the inter-war military aircraft industry. Airframe designs had little IP protection before 1926, but changes passed by Congress in 1926 provided airframe manufacturers with enhanced property rights over the new designs they produced. We show that granting property rights to airframe producers increased innovation in airframes, but slowed down innovation in aero-engines, a complementary good where there was no change in the availability of IP protection. We propose and test a simple theory that explains these patterns.
|World War II and the Industrialization of the American South|
When private incentives are insufficient, a big push by government may lead to industrialization. This paper uses mobilization for World War II to test the big push hypothesis in the context of postwar industrialization in the American South. Specifically, I investigate the role of capital deepening at the county level using newly assembled data on the location and value of wartime investment. Despite a boom in manufacturing activity during the war, the evidence is not consistent with differential growth in counties that received more investment. This does not rule out positive effects of mobilization on firms or sectors, but a decisive role for wartime capital deepening in the Souths postwar industrial development should be viewed more skeptically.

|Ownership and the Price of Residential Electricity: Evidence from the United States, 1935-1940|
with : w22254
In this paper, we quantify the difference between public and private prices of residential electricity immediately before and after major federal reforms in the 1930s and 1940s. Previous research found that public prices were lower in a sample of large, urban markets. Based on new data covering over 15,000 markets and nearly all electricity generated for residential consumption, we find the difference between public and private prices was small in 1935 and negligible in 1940 for typical levels of monthly consumption. These findings are consistent with a market for ownership that helped to discipline electricity prices during this period. That is, private rents were mitigated by the threat that municipalities would use public ownership to respond to constituent complaints and public rents w...

|National Policy for Regional Development: Historical Evidence from Appalachian Highways|
with : w22073
How effective are policies aimed at integrating isolated regions? We answer this question in the context of a highway system in one of the poorest regions in the United States. With construction starting in 1965, the Appalachian Development Highway System ultimately consisted of over 2,500 high-grade road miles. We use a simple model of interregional trade to motivate our empirical analysis, which quantifies the relationship between market access and income. We then calibrate the model to evaluate the aggregate impact of the ADHS and compare this with alternative counterfactual proposals. We find that removing the ADHS would have reduced total income by $53.7 billion in the United States with $22 billion of the losses in Appalachian counties. Our findings highlight the potential aggregate ...
