Eric Zwick

Associate Professor of Finance and Fama Faculty Fellow

Eric Zwick studies the interaction between public policy and corporate behavior, with a focus on fiscal stimulus, taxation and housing policy. His research draws insights from finance and behavioral economics while using a variety of methods: new data, natural experiments, theory and anecdotal exploration.

Zwick is particularly interested in the problems that small and medium-sized private firms and new ventures face, from the perspective of owners, investors, managers and workers. A secondary area of interest concerns the role of bounded rationality and imperfect information in the design of policies that promote behavior change. This work focuses on determinants of habit formation in health and workforce productivity settings.

Zwick earned a Ph.D. and M.A. in business economics from Harvard University and a B.A. in economics and mathematics with high honors from Swarthmore College. Prior to grad school, he worked as a research assistant at the National Bureau of Economic Research and as a web and software developer for several start-ups and non-profits.

New: Capitalists in the Twenty-first Century
Date Posted: Feb  23, 2019
Have the idle rich replaced the working rich at the top of the U.S. income distribution? Using tax data linking 11 million firms to their owners, this paper finds that entrepreneurs who actively manage their firms are key for top income inequality. Most top income is non-wage income, a primary source of which is private business profit. These profits accrue to working-age owners of closely-held, mid-market firms in skill-intensive industries. Private business profit falls by three-quarters after owner retirement or premature death. Classifying three-quarters of private business profit as human capital income, we find that most top earners are working rich: they derive most of their income from human capital, not physical or financial capital. The human capital income of private business owners exceeds top wage income and top public equity income. Growth in private business profit is explained by both rising productivity and a rising share of value added accruing to owners.

REVISION: Kinky Tax Policy and Abnormal Investment Behavior
Date Posted: May  10, 2018
This paper documents tax-minimizing investment, in which firms accelerate capital purchases near fiscal year-end to reduce taxes. Between 1984 and 2013, average investment in fiscal Q4 exceeds the average of fiscal Q1 through Q3 by 37%. Q4 spikes occur in the U.S. and internationally. Research designs using variation in firm tax positions and the 1986 Tax Reform Act show that tax minimization causes spikes. Spikes increase when firms face financial constraints or higher option values of waiting. We develop an investment model with tax asymmetries to rationalize these patterns. Models without purchase-year, tax-minimization motives are unlikely to fit the data.

REVISION: Stimulating Housing Markets
Date Posted: Sep  13, 2016
This paper studies temporary policy incentives designed to address capital overhang by inducing asset demand from buyers in the private market. Using variation across local geographies in ex ante program exposure and a difference-in-differences design, we find that the First-Time Homebuyer Credit induced a cumulative increase in home sales of at least 382 thousand, or 7.4 percent, nationally. We find little evidence of a sharp reversal of the policy response; instead, demand appears to come from several years in the future. The program likely sped the process of reallocating homes from distressed sellers to high value buyers and stabilized house prices. The response is concentrated in the existing home sales market, implying the stimulative effects of the program were less important than its role in accelerating reallocation.
