Political preferences in the US are highly correlated with population density, at national, state, and metropolitan-area scales. Using new data from voter registration records, we assess the extent to which this pattern can be explained by…

We develop a general and unified model in which a continuum of agents conduct directed random searches for counterparties. Our results provide the first probabilistic foundation for static and dynamic models of directed search (including the…

We provide a unified analysis of the predictive risk of ridge regression and regularized discriminant analysis in a dense random effects model. We work in a high-dimensional asymptotic regime where p and n grow to infinity and p/n converges…

We consider a game-theoretical multi-agent learning problem where the feedback information can be lost during the learning process and rewards are given by a broad class of games known as variationally stable games. We propose a simple variant of…

We consider a system with an evolving state that can be stopped at any time by a decision maker (DM), yielding a state-dependent reward. The DM does not observe the state except for a limited number of monitoring times, which he must choose, in…

This article summarizes the Opportunity Zone incentive in the Tax Cuts and Jobs Act by providing descriptive statistics on the selected zones, outlining considerations for investors, and using data on the New…

In a multi-armed bandit (MAB) problem a gambler needs to choose at each round of play one of K arms, each characterized by an unknown reward distribution. Reward realizations are only observed when an arm is selected, and the gambler’s objective…

We use a simple three-sector model to narrate the economic history of Argentina during the twentieth century as seen through the prism of its integration into and dis-integration from the world economy. Assuming that capital moves between the…

We analyze a model of policymaking in which only one actor, e.g., a bureaucratic agency or a well-funded interest group, has the capacity to develop high-quality policy proposals. By virtue of her skills, this actor has an effective…

The current research examines how political identity shapes preferences for objects and messages that highlight either equality or hierarchy. We find that liberals show a greater preference for an object associated with less as opposed to more…

Classic arguments for decentralization, augmented by ideas about how participation empowers the poor, motivate the widely used approach in foreign aid called community-driven development (CDD). CDD devolves control over the…

The Facility Guidelines Institute (FGI), a not-for-profit corporation founded in 1998, seeks to gather perspectives on challenges facing patients and clinicians in clinical spaces from which ideas can be gleaned to focus further research and…

Many U.S. organizations lack the resources to enter all cartridge cases from crime scenes and test-fires into the National Integrated Ballistic Information Network and search for hits. This paper summarizes the main question in (1): if ballistic…

This chapter traces the development of research on social movement outcomes or consequences over three distinct phases, with an eye toward understanding how this research has impacted organizational studies research on how social movements impact…

In many important machine learning applications, the training distribution used to learn a probabilistic classifier differs from the testing distribution on which the classifier will be used to make predictions. Traditional methods correct the…

This paper studies multi-tier supply chain networks in the presence of disruption risk. Firms decide how to source their inputs from upstream suppliers so as to maximize their expected profits, and prices of intermediate goods are set so that…

Millions of poor smallholder farmers produce global commodities,

often through illegal deforestation. Multinational commodity buyers have

committed to halt illegal deforestation and improve farmers’ livelihoods in

their…

We consider a competitive facility location problem on a network, in which consumers are located on the vertices and wish to connect to the nearest facility. Knowing this, competitive players locate their facilities on vertices that capture the…
