NYU launches new Master of Science in Quantitative Economics

NYU's MS in Quantitative Economics is a cutting-edge program for students with research-oriented ambitions in economics, such as a demanding doctoral program, or employment in technology, finance and research in both the private or public sectors. Drawing on the combined resources of the Economics Departments of the Faculty of Arts and Science and NYU’s Stern School, the program is streamlined and sequenced to get you where you need to go with maximal stimulation, speed and efficiency.

Adam Brandenburger and Stefan Bucher's "Divisive Normalization is an Efficient Code for Multivariate Pareto-Distributed Environments"

Divisive normalization is a canonical computation in the brain, observed across neural systems, that is often considered to be an implementation of the efficient coding principle. We provide a theoretical result that makes the conditions under which divisive normalization is an efficient code analytically precise: We show that, in a low-noise regime, encoding an n-dimensional stimulus via divisive normalization is efficient if and only if its prevalence in the environment is described by...

Entropy

Adam Brandenburger, Pierfrancesco La Mura, and Stuart Zoble's "Rényi Entropy, Signed Probabilities, and the Qubit"

The states of the qubit, the basic unit of quantum information, are 2×2 positive semi-definite Hermitian matrices with trace 1. We contribute to the program to axiomatize quantum mechanics by characterizing these states in terms of an entropic uncertainty principle formulated on an eight-point phase space. We do this by employing Rényi entropy (a generalization of Shannon entropy) suitably defined for the signed phase-space probability distributions that arise in representing quantum states.

Luis Cabral and Gabriel Natividad's "Bundling Sequentially Released Durable Goods," published in the Journal of Industrial Economics

Suppose two durables are sequentially released and suppose that consumer valuations of these goods are positively correlated. By the time the second good is released, high-valuation buyers are out of the market for the first good. Therefore, a bundle can be targeted at the low-valuation consumers without violating the high-valuation consumers' incentive compatibility constraint. We test the model's predictions on data from retail DVD sales in the 2000's. Consistent with theory, our estimates...

Larry White's "The Dead Hand of Cellophane and the Federal Google and Facebook Antitrust Cases: Market Delineation Will Be Crucial" published in The Antitrust Bulletin

The U.S. Department of Justice (DOJ) and Federal Trade Commission (FTC) monopolization cases against Google and Facebook, respectively, represent the most important federal nonmerger antitrust initiatives since (at least) the 1990s. As in any monopolization case, market delineation will be a central feature of both cases—as it was in the du Pont Cellophane case of sixty-five years ago. Without a delineated market, how can one determine whether a company has engaged in monopolization?

Larry White's guest article, "A Riff and a Half on the Delineation of Relevant Markets in Antitrust Cases" in the Network Law Review

Excerpt from the Network Law Review -- "In this note, I wish to make two points. First – and most important: A satisfactory paradigm for delineating relevant markets in unilateral monopolization cases – which involve allegations of restrictive, exclusionary, and/or predatory actions, or abuse of dominance – has not yet appeared in the litigation of monopolization cases. Unfortunately, the market delineation paradigm that has been successfully used for delineating relevant markets for..."

Michael Dickstein, Kate Ho, and Nathaniel Mark's new NBER working paper, "Market Segmentation and Competition in Health Insurance"

In the United States, households obtain health insurance through distinct market segments. We explore the economics of this segmentation by comparing coverage provided through small employers versus the individual marketplace. Using data from Oregon, we find households with group coverage spend 26% less on covered health care than households with individual coverage yet face higher markups. We develop a model of plan choice and health spending to estimate preferences in both markets and...

Luis Cabral and Lei Xu's "Seller reputation and price gouging: Evidence from the COVID-19 pandemic," published in the Economic Inquiry

From mid-January to March 2020, 3M masks sold on Amazon by third party sellers were priced 2.4 times higher than Amazon's 2019 price. However, this price increase was not uniform across sellers. We estimate that when Amazon is stocked out (one of our measures of scarcity) new (entrant) sellers increase price by 178%, whereas the continuing sellers' increase is limited to 56.7%. This is consistent with the idea that seller reputation limits the extent of profitable price gouging. Similar...

Niklas Engbom's "Contagious Unemployment," published by the Centre for Economic Policy Research

Recent micro evidence of how workers search for jobs is shown to have critical implications for the macroeconomic propagation of labor market shocks. Unemployed workers send over 10 times as many job applications in a month as their employed peers, but are less than half as likely per application to make a move. I interpret these patterns as the unemployed applying for more jobs that they are less likely to be a good fit for. During periods of high unemployment, it consequently becomes harder...

Paul Scott, Jonathan Elliott, Georges V. Houngbonon, and Marc Ivaldi's "Market Structure, Investment and Technical Efficiencies in Mobile Telecommunications," published by the Centre for Economic Policy Research

Paul Scott and coauthors develop a model of competition in prices and infrastructural investment among mobile network providers. Market shares and service quality (download speed) are simultaneously determined, for demand affects the network load just as delivered quality affects consumer demand. While consolidation typically has adverse impacts on consumer surplus, economies of scale push in the other direction. Consumer surplus is maximized at a moderate number of firms, and that the...

Larry White's "Rethinking Antitrust," published in the Milken Institute Review

Antitrust policy in the U.S. has recently gained an unusual amount of media attention. There are critics who have argued that a major overhaul of antitrust policy is needed. This paper argues that instead there are some important but more modest changes that could go a long way toward significantly strengthening the role that antitrust can play in keeping the U.S. economy competitive, vibrant, and innovative.
