This paper shows the importance of technological synergies among heterogeneous firms for aggregate fluctuations. First, we document six novel empirical facts using microdata that suggest the existence of important technological synergies between trading firms, the presence of positive...

Despite extensive use of bargaining models in economics and despite Becker's insistence on the importance of altruism in families, the theoretical literature on bargaining ignores altruism and assumes that everyone is an egoist. This paper shows that incorporating altruism into cooperative...

We introduce a novel approach to solving dynamic programming problems, such as those in many economic models, on a quantum annealer, a specialized device that performs combinatorial optimization. Quantum annealers attempt to solve an NP-hard problem by starting in a quantum superposition of all...

We formulate a quantitative dynamic equilibrium theory of trade in the fed funds market, calibrate it to fit a comprehensive set of marketwide and micro-level cross-sectional observations, and use it to make two contributions to the operational side of monetary policy implementation. First, we...

How does the presence of risk sharing affect sorting patterns on productive attributes when there are complementarities among partners' skills in match output? We develop a matching model in which risk-averse agents, who differ in skills, match pairwise for productive purposes. Match output has...

We propose a new sorting framework: composite sorting. Composite sorting comprises of (1) distinct worker types assigned to the same occupation, and (2) a given worker type simultaneously being part of both positive and negative sorting. Composite sorting arises when fixed investments mitigate...

Kidney exchange emerges as a pioneering application in the early stages of market design. In contrast to most other successful applications in the field, where design economists primarily serve as consultants to decision-makers, in the context of kidney exchange, they assumed the role of...

Are labor markets in higher-income countries more meritocratic, in the sense that worker-job matching is based on skills rather than idiosyncratic attributes unrelated to productivity? If so, why? And what are the aggregate consequences? Using internationally comparable data on worker skills and...

We study the volunteer's dilemma in environments with heterogeneous preferences and private information. We characterize the efficiency properties of equilibrium, which is a departure from all the previous literature that focuses only on the probability of group success. While the probability of...

The possibility that individuals may derive utility from the mere fact of holding wealth has long been recognized. A simple intertemporal model featuring utility from accumulation is used here to examine consumption and savings, the choice between inter vivos gifts and bequests (both to...
