"The Gains from Reshaping Infrastructure: Evidence from the Division of Germany" (Job Market Paper)
This paper quantifies the gains from infrastructure investments and shows that reshaping the highway network after a large economic shock, the Division of Germany, had positive welfare and output effects. To address the endogeneity between infrastructure and economic outcomes, I develop a multi-region quantitative trade model where infrastructure is chosen by the government to maximise welfare. I calibrate the model to the prewar German economy and estimate the key structural parameter of the model using the prewar Highway Plan. I exploit the Division of Germany, a large-scale exogenous shock to economic fundamentals, to show that the model can predict changes in highway construction after the Division. Using newly collected data, I document that half of the new highway investments deviated from the prewar Highway Plan. I find that the reallocation of these investments (one-third of the network) led to increases of 1.08% of welfare and 1.35% of real income annually. Finally, I measure the cost of path-dependence and show that reshaping the full network could have increased welfare by 1.62% and real income by 1.6%.

"Texting Complaints to Politicians: Name Personalization and Politicians’ Encouragement in Citizen Mobilization” with Grossman, G., Michelitch, K., Santamaria, M. (2017), Comparative Political Studies, 50(10): 1325-1357.
Poor public service provision and government accountability is commonplace in low-income countries. Although mobile phone-based platforms have emerged to allow constituents to report service deficiencies to government officials, they have been plagued by low citizen participation. We question whether low participation may root in low political efficacy to politically participate. In the context of a text-message reporting platform in Uganda, we investigate the impact of adding efficacy-boosting language to mobilization texts - (a) citizen name personalization and (b) politician encouragement - on citizens' willingness to report service deficiencies to politicians via text messages. Both treatments, designed to increase internal and external efficacy, respectively, have a large, positive effect on participation. The results are driven by traditionally less internally efficacious constituents (females and less externally efficacious constituents (those represented by opposition party members), respectively.
