Learning Under Random Distributional Shifts
By: Kirk Bansak, Elisabeth Paulson and Dominik Rothenhäusler
Algorithmic assignment of refugees and asylum seekers to locations within host
countries has gained attention in recent years, with implementations in the U.S.
and Switzerland. These approaches use data on past arrivals to generate machine
learning models that can... View Details

On the Impact of Actionable Explanations on Social Segregation
By: Ruijiang Gao and Himabindu Lakkaraju
As predictive models seep into several real-world applications, it has become critical to ensure that individuals who are negatively impacted by the outcomes of these models are provided with a means for recourse. To this end, there has been a growing body of research... View Details

Cooperation Can Emerge in Prisoner’s Dilemma from a Multi-species Predator Prey Replicator Dynamic
By: Elisabeth Paulson and Christopher Griffin
In this paper we study a generalized variation of the replicator dynamic that involves several species and sub-species that may interact. We show how this dynamic comes about from a specific finite-population model, but also show that one must take into consideration... View Details

Designing, Not Checking, for Policy Robustness: An Example with Optimal Taxation
By: Benjami Lockwood, Afras Y. Sial and Matthew C. Weinzierl
Economists typically check the robustness of their results by comparing them across plausible ranges of parameter values and model structures. A preferable approach to robustness—for the purposes of policymaking and evaluation—is to design policy that takes these... View Details

Accounting for Crises
While neoclassical models suggest that improving the quality of financial information tightens the link between the realization of the information and the underlying fundamentals, models of recent crises suggest that higher information quality can generate... View Details

Measuring Consumer Preferences for Video Content Provision via Cord-Cutting Behavior
By: Jeffrey Prince and Shane Greenstein
The television industry is undergoing a generational shift in structure; however, many demand-side determinants are still not well understood. We model how consumers choose video content provision among over-the-air (OTA), paid subscription to cable or satellite, and... View Details

Government and Markets: Toward a New Theory of Regulation
By: Edward J. Balleisen and David A. Moss
After two generations of emphasis on governmental inefficiency and the need for deregulation, we now see growing interest in the possibility of constructive governance, alongside public calls for new, smarter regulation. Yet there is a real danger that regulatory... View Details

No Taxation without Information
Tax evasion generates billions of dollars of losses in government revenue and creates large distortions, especially in developing countries. A growing, mostly theoretical literature argues that information flows are central to understanding effective taxation. This... View Details

Evaluation and Learning in R&D Investment
By: Alexander P. Frankel, Joshua L. Krieger, Danielle Li and Dimitris Papanikolaou
We examine the role of spillover learning in shaping the value of exploratory versus incremental
R&D. Using data from drug development, we show that novel drug candidates generate more
knowledge spillovers than incremental ones. Despite being less likely to reach... View Details

Limited Arbitrage in Mergers and Acquisitions
By: Malcolm Baker and Serkan Savasoglu
A diversified portfolio of risk arbitrage positions produces an abnormal return of 0.6-0.9% per month over the period from 1981 to 1996. We trace these profits to practical limits on risk arbitrage. In our model of risk arbitrage, arbitrageurs' risk-bearing capacity... View Details

Sex Selection and the Indian Marriage Market
I consider the widespread phenomenon of sex ratios skewed by parental preference. Edlund (1999) proposes that if parents prefer sons and permit only women to marry up in social class, sexes will segregate by wealth in equilibrium. Using data on 30,000 Indian children,... View Details
