February 2017Company Stock Reactions to the 2016 Election Shock: Trump, Taxes and Trade
with Richard J. Zeckhauser, Alexandre Ziegler: w23152
The election of Donald J. Trump as the 45th President of the United States of America on 11/8/2016 came as a surprise. Markets responded swiftly and decisively. This note investigates both the initial stock market reaction to the election, and the longer-term reaction through the end of 2016. We find that the individual stock price reactions to the election – that is, the market’s vote – reflect investor expectations on economic growth, taxes, and trade policy. Heavy industry and banking were relative winners, whereas healthcare, medical equipment, pharmaceuticals, textiles, and apparel were among the relative losers. High-beta stocks and companies with a hitherto high tax burden benefited from the election. Although internationally-oriented companies may profit under some plans of the new...
February 2015Tips and Tells from Managers: How Analysts and the Market Read Between the Lines of Conference Calls
with Marina Druz, Richard J. Zeckhauser: w20991
Stock prices react significantly to the tone (negativity of words) managers use on earnings conference calls. This reaction reflects reasonably rational use of information. “Tone surprise” – the residual when negativity in managerial tone is regressed on the firm’s recent economic performance and CEO fixed effects – predicts future earnings and analyst uncertainty. Prices move more, as hypothesized, in firms where tone surprise predicts more strongly. Experienced analysts respond appropriately in revising their forecasts; inexperienced analysts overreact (underreact) to tone surprises in presentations (answers). Post-call price drift, like post-earnings announcement drift, suggests less-than-full-use of information embedded in managerial tone.
December 2012Solomonic Separation: Risk Decisions as Productivity Indicators
with Nolan Miller, Richard J. Zeckhauser: w18634
A principal provides budgets to agents (e.g., divisions of a firm or the principal's children) whose expenditures provide her benefits, either materially or because of altruism. Only agents know their potential to generate benefits. We prove that if the more "productive" agents are also more risk-tolerant (as holds in the sample of individuals we surveyed), the principal can screen agents and bolster target efficiency by offering a choice between a nonrandom budget and a two-outcome risky budget. When, at very low allocations, the ratio of the more risk-averse type's marginal utility to that of the other type is unbounded above (e.g., as with CRRA), the first-best is approached. -- A biblical opening enlivens the analysis.

June 2003Choosing (and reneging on) exchange rate regimes
with Alberto Alesina: w9809
We use data on announced and actual exchange rate arrangements to ask which countries follow de facto regimes different from their de iure ones, that is, do not do what they say. Our results suggest that countries with poor institutional quality have difficulty in maintaining pegging and abandon it more often. In contrast, countries with relatively good institutions display fear of floating, i.e. they manage more than announced, perhaps to signal their differences from those countries incapable of maintaining promises of monetary stability.
