[Academic Events] Monday Lunch Seminar Giovanni Mastrobuoni (Collegio Carlo Alberto)

"Open or Close the Door? Prison Conditions and Recidivism" Abstract The question of how prison conditions affect recidivism is very important. In designing a prison system, one would want to know the answer. We estimate the effect on recidivism of replacing time served in a common closed-cell prison with time served in an open-cell one, mimicking an experiment…

 "The effects of collective bargaining on employment and growth" Abstract This paper analyses the employment effects of the Italian sectoral wage bargaining system. The study is based on high-frequency, comprehensive and updated information on employment and wages derived from administrative data on private-sector social security contributions, matched with precise information on the economic content of…

Monday Lunch Seminar Paolo Ghirardato (Collegio Carlo Alberto) and Daniele Pennesi

"A General Theory of Subjective Mixtures" Abstract We provide a framework for constructing subjective mixtures which requires neither the Certainty Independence nor the Monotonicity axiom, replacing them with much weaker "local'' properties, and which --as we show by means of several examples-- can thus serve as a purely subjective foundation to most of the recent…

Monday Lunch Seminar Edoardo Grillo (Collegio Carlo Alberto)

"Dynamic Campaign Spending" Abstract We build a model of electoral campaigning in which two candidates allocate money over time to control the movement of relative popularity. If any gain in a candidate's popularity tends to decay over time (making it harder for the candidate to maintain or increase her lead when she is already ahead)…

"Price Setting on a Network" abstract Most products are produced and sold by supply chain networks, where an interconnected network of producers and intermediaries set prices to maximize their profits. I show that under a few technical assumptions, there is a unique equilibrium in a price-setting game on a network. The key distortion in the…

"Pink Work: Same-Sex Marriage, Employment and Discrimination" Abstract This paper analyzes how the legalization of same-sex marriage in the U.S. affected gay and lesbian couples in the labor market. Results from a difference-in-difference model emphasize that both partners in same-sex couples were more likely to be employed, to have a full-time contract, and to work…

"Explaining Recent Trends in US School Segregation: 1988-2014" Abstract We analyze trends in public school segregation throughout the United States from 1988 to 2014. While predominantly minority schools have increased in prevalence, predominantly white schools have decreased in prevalence at a faster rate. Overall, the majority of commuting zones in the US have experienced decreasing…

Monday Lunch Seminar Julian Wright (National University of Singapore)

"Steering by information intermediaries" Abstract We provide a model of an intermediary that can steer consumers towards particular firms due to its information advantage. Unlike most existing models of steering, our model allows firms to compete for consumers through commissions and prices. We explore the implications of steering for market outcomes, showing how steering reverses…

Monday Lunch Seminar Nicola Borri (LUISS)

"Limited Participation and Local Currency Sovereign Debt" Abstract Emerging country governments increasingly issue bonds denominated in local currency and the share of this market held by foreign investors, once negligible, has been progressively growing. This paper presents a model of segmented markets, in which specialized foreign investors can access multiple local markets only after paying an…

Monday Lunch Seminar Andrei Hagiu (MIT Sloan)

"Platforms and the exploration of new products" abstract The introduction of new but risky products and sellers are key to the growth of platforms. Exploration by current buyers helps future buyers better value these products and sellers. This externality across buyers raises the possibility that there may be too little exploration in the absence of…

Monday Lunch Seminar Willa Friedman (University of Houston)

"What Happens to Babies Born During Health-Worker Strikes?" abstract Health worker strikes are a growing but still under-studied phenomenon in Sub-Saharan Africa. In the past few years alone, health worker strikes limited service provision in more than 18 countries. We use panel data from Kenya linked with a newly compiled record of the timing and…

"How long do healthy habits last? The role of prices" Abstract When a policy gives temporary incentives for healthy behaviors, how long does the impact last? I study the U.S. Special Supplemental Nutrition Program for Women, Infants, and Children, which gives vouchers for healthy foods. Using household-level scanner data, I find that the effect of…
