Cryptocurrency Investing: Stimulus Checks and Inflation Expectations (with Darren Aiello, Tetyana Balyuk, Marco Di Maggio, Mark Johnson, and Jason Kotter) Revise & Resubmit, Review of Financial Studies

Abstract: We provide a first look into the factors that affect retail investing in cryptocurrencies. We use consumer transaction data to examine how household characteristics, liquidity shocks, and hedging requirements shape the crypto investment decisions of millions of U.S. households. We find that—similar to traditional investing—crypto investing responds to wealth, risk attitudes, and liquidity constraints. Yet, crypto investing is more responsive than after-tax traditional investment flows to overall market conditions. We then show that investors' budget constraints affect crypto investing, in line with portfolio choice theories. We find that relaxing budget constraints through receiving stimulus payments increases crypto investing. Tighter future budget constraints due to higher expected inflation also increase crypto investing, consistent with hedging motives. Our findings are important for understanding this new high-risk, high-return asset class and designing effective regulations in this rapidly evolving space.

Policy News and Stock Market Volatility (with Nicholas Bloom, Steve Davis, and Kyle Kost) (Data) Revise & Resubmit, Journal of Financial Economics 

Abstract: We exploit the text in newspapers and 10-K filings to quantify the drivers of aggregate and firm-level stock market volatility. We first create a newspaper-based Equity Market Volatility (EMV) tracker that moves closely with the VIX and the volatility of returns on the S&P 500. Parsing the underlying text, we then construct forty category-specific EMV trackers. News about commodity markets, interest rates, real estate markets, aggregate activity and inflation figure prominently in EMV articles, with large category-specific variation over time. Policy news is another major source of market volatility: 30 percent of EMV articles discuss tax policy, 30 percent discuss monetary policy, and 25 percent refer to some form of regulation. Trade policy news went from a virtual nonfactor in market volatility to a leading source after U.S.-China trade tensions escalated. Next, we use 10-K filings to quantify firm-level exposures to the same forty risk categories. Combining our newspaper-based measures with our textual analysis of 10-K filings, we obtain monthly firm-level risk exposure measures. Finally, we show that these measures are highly statistically significant in explaining the firm-level structure of realized equity market volatilities at the monthly frequency, even after conditioning on firm effects, time effects and industry-time effects.

What Triggers Stock Market Jumps? (with Nicholas Bloom, Steve Davis, and Marco Sammon) (Data)

Abstract: Based on readings of next-day newspaper articles, we catalog the proximate cause and geographic source of all largest 1% of daily stock market movements in 14 countries over the past 30 years. Our catalog extends back to 1930 for the United Kingdom and to 1900 for the United States. Using the United States as a test case, we compare categorizations across several newspapers and human coders, obtaining consistent results. News about the United States plays a disproportionate role in triggering large equity moves around the world in recent decades, relative to the U.S. share of world output. The reverse pattern, of large U.S. equity moves in response to foreign news, is comparatively rare. Across almost all countries, the share of large stock market moves associated with government policy increased during and after the Global Financial Crisis of 2008-09. We show that shocks of different types and geographic origins are associated with significant differences in returns and both implied and realized volatility.

Correlation in State and Local Tax Changes (with Pawel Janas and Lorenz Kueng) (State Tax Data; County Tax Data) Reject & Resubmit, Journal of Public Economics

Abstract: We develop a comprehensive dataset of state and local taxes from 2000-2015 that includes personal income taxes, property taxes, corporate income taxes, sales taxes, estate taxes and excise taxes. We illustrate how state and local taxes have changed over time, over business cycles, and to what extent different taxes co-move within a state or locality. We observe large differences in the mix of taxes across states and local jurisdictions and note that these differences have become more pronounced over time. Moreover, we find that taxes of different types tend to co-move within a jurisdiction, highlighting the importance for researchers to take into account the entirety of the tax system, rather than just a single tax type, when examining responses to tax changes. At both a state and local level, increases in tax rates of all types are associated with increased tax revenue but worsened business conditions and employment.

The Determinants of The Chinese Household Savings Rate  (with Efraim Benmelech, Zhishu Yang, and Jacky Zhang)

Abstract: China’s high household savings rate has attracted great academic interest but remains a puzzle. Potential explanations include demographics, policy actions, and financial causes. However, a lack of reliable microlevel data makes it difficult to assess the relative importance of each factor. This paper provides new answers to this question by using income and spending data from two large Chinese banks alongside linkages to demographic characteristics and administrative records covering marriage and births. Our results suggest that income growth, financial instability, and credit access, rather than such directives as the one-child policy, are the primary causes of high saving rates among Chinese households.

Corporate Taxes and Retail Prices (with Stephen Sun and Constantine Yannelis)

Abstract: Higher corporate taxes must result in lower payments to shareholders, lower wages, or higher product prices. We study the impact of corporate taxes on barcode-level product prices using linked survey and firm-level data. Our empirical strategy exploits the dichotomy between the location of production and the location of sales, providing estimates free from confounding local demand shocks. We find significant effects of corporate taxes on prices with a net-of-tax elasticity of 0.24. We find null effects on prices for firms subject to personal income taxes. In excess of 40% of corporate tax incidence may fall on consumers, suggesting that models used by policymakers significantly underestimate the incidence of corporate taxes on consumers. Pass-through is larger for products purchased by high-income households, higher priced goods, and in less competitive markets.

Effects of Cryptocurrency Wealth on Household Consumption and Investment (with Darren Aiello, Tetyana Balyuk, Marco Di Maggio, Mark Johnson, and Jason Kotter)

Abstract: This paper uses transaction-level data across millions of accounts to identify cryptocurrency investors and evaluate how fluctuations in individual crypto wealth affect household consumption, equity investment, and local real estate markets. We estimate an MPC out of unrealized crypto gains that is more than double the MPC out of unrealized equity gains but smaller than the MPC from exogenous cash flow shocks. This MPC is mostly driven by increases in cash/check spending and mortgages. Moreover, households sell crypto to increase both discretionary as well as housing spending. As a result, crypto wealth causes house price appreciation—counties with higher crypto wealth see higher growth in home values following high crypto returns. Our results indicate that cryptocurrencies have substantial spillover effects on the real economy through consumption and investment into other asset classes.
