[Abstract]
Regulating the price of productivity-enhancing inputs can allow governments to facilitate the diffusion of existing technologies but deter private firms from investing in innovation and introducing superior technologies. This project studies the demand and supply-side consequences of price controls on genetically engineered (GE) cotton seeds in India. Leveraging the differential timing and intensity of this policy across states, we show that the government-mandated price reduction increased farmers' adoption of GE seeds by 23 percentage points and decreased the costs of cultivating cotton by 24%. Although seed firms did not incur significant losses in the short term, the number of new hybrid varieties fell abruptly in the aftermath of the policy. Using newly assembled data from experimental field trials across India, we show that agronomic yields of new varieties worsen by 28% in price-controlled states. To quantify the overall welfare implications of price and quality responses, we develop and estimate a structural model of demand and supply for seeds. Preliminary results indicate that price controls increased aggregate farmer surplus. However, ignoring endogenous quality adjustments substantially overstates welfare gains for farmers.

Brigandage and the Political Legacy of Monarchical Legitimacy in Southern Italy (with Cristoforo Pizzimenti)

[Abstract]   [PDF]   [SSRN]
Political legitimacy plays a pivotal role in securing the effectiveness of a governing system yet, amidst power struggles, rulers face the peril of losing it. This paper studies whether a historical shock in the legitimacy of monarchic rule can have long-term, intergenerational consequences on political attitudes. The unification of Italy ignited a violent reaction against the new ruler in its southern provinces known as the "Great Brigandage". We use fixed-effects regressions with a wide set of controls and an instrumental variable approach based on military suitability of the terrain in order to show that, ceteris paribus, municipalities exposed to brigandage in the 1861-1870 period had lower turnout in the 1946 Institutional Referendum and were significantly less likely to vote for the survival of the monarchy. We interpret our findings as evidence that latent preferences toward political systems are endogenously shaped by historical events and can be brought to the surface by changes in the institutional environment.
