Risk and the Cross-Section of Stock Returns
By: Mark Seasholes, Radu Burlacu, Patrice Fontaine and Sonia Jimenez-Garces
This paper mathematically transforms unobservable rational expectation equilibrium model parameters (information precision and supply uncertainty) into a single variable that is correlated with expected returns and that can be estimated with recently observed data. Our... View Details

Trade and Industrial Policy in Supply Chains: Directed Technological Change in Rare Earths
By: Laura Alfaro, Harald Fadinger, Jay Schymik and Gede Virananda
Trade and industrial policies, while primarily intended to support domestic industries, may unintentionally stimulate technological progress abroad. We document this mechanism in the case of rare earth elements (REEs)—critical inputs for manufacturing at the knowledge... View Details

Nonsimultaneous Chains and Dominos in Kidney Paired Donation—Revisited
By: Itai Ashlagi, Duncan S. Gilchrist, Alvin E. Roth and Michael A. Rees
Since 2008 kidney exchange in America has grown in part from the incorporation of non-directed donors in transplant chains rather than simple exchanges. It is controversial whether these chains should be performed simultaneously ("domino paired donation," DPD) or... View Details

The Need for (long) Chains in Kidney Exchange
By: Itai Ashlagi, David Gamarnik, Michael A. Rees and Alvin E. Roth
It has been previously shown that for sufficiently large pools of patient-donor pairs, (almost) efficient kidney exchange can be achieved by using at most 3-way cycles, i.e., by using cycles among no more than 3 patient-donor pairs. However, as kidney exchange has... View Details
