This paper introduces an oligopoly model that includes three actors: a cartel (comprising two or more firms that operate like one merged company), a group of competing fringe firms, and a welfare maximizing antitrust authority. The cartel is the Stackelberg quantity leader and the fringe firms...

We propose no-arbitrage term structure models in which the volatility factors followGARCH processes. The models’ tractability is similar to that of canonical affine termstructure models, but they capture the conditional variances of yields much more accurately.We estimate a model with one...

Most doctors in the NRMP match with one of their most-preferred internship programs. However, surveys indicate doctors’ preferences are similar, suggesting a puzzle: how can so many doctors match with their top choices when positions are scarce? We provide one possible explanation. We show...

This paper uses reinforcement learning (RL) to approximate the policy rules of banks participating in a high-value payments system. The objective of the agents is to learn a policy function for the choice of amount of liquidity provided to the system at the beginning of the day. Individual...

We revisit the uncapacitated single-period joint assortment and inventory problem in the presence of dynamic (stockout-based) substitution behavior (i.e., the so-called "dynamic assortment problem"). This is a very important practical problem faced by many retailers; at the same time, it is also...

Adam Smith’s economic system followed his philosophical convictions. The policy conclusions came before the analysis. To support his policy of Free Trade, or rather, the ‘system of liberty’, Adam Smith gradually built up his economic system , from the Lectures on Jurisprudence to the...

We analyze how interdependencies in financial networks can lead to self-fulfilling insolvencies and multiple possible equilibrium outcomes. We show that multiplicity arises if and only if there exists a certain type of dependency cycle in the network, and characterize banks' solvency in any...

This paper studies the non-parametric identification of the discount factor and utility function in the class of dynamic discrete-continuous choice (DDCC) models. In contrast to the discrete-only model we show the discount factor is identified. Our results further highlight why Euler equation...

In many organizations, employees enjoy significant discretion regarding project selection. If projects differ in their informativeness about an employee’s quality, project choices will be distorted whenever career concerns are important. We analyze a model in which an organization can shape...

In a crisis, when faced with insolvency, banks can sell stock in a dilutive offering in thestock market and borrow money in order to raise funds. We propose a simple model to find themaximum amount of new funds the banks can raise in these ways. To do this, we incorporatemarket confidence of the...
