Corporate Governance and the Timing of Earnings Announcements

Review of Finance 2014 18(6), 2003-2044 open access
Using comprehensive time stamp data on earnings announcements collected from newswires, we show that earnings news announced within trading hours results in approximately 50% smaller immediate reaction compared to similar earnings announced outside trading hours. Negative news tends to be announced during trading hours, which, together with the reduced response, may allow for managerial opportunistic behavior. We also provide evidence that announcement timing is affected by internal corporate governance. Recent regulations that tightened firms’ governance are associated with a significant shift to announcing outside trading hours, especially for firms with better corporate governance. Our surveys of corporate managers corroborate these results.

A Model of Trading Volume with Tax-Induced Heterogeneous Valuation and Transaction Costs

Journal of Financial Intermediation 1996 5(4), 340-371 open access
We develop a model of trading volume when agents have different valuation and face transaction costs. In particular, the differential valuation is induced by differential tax status which generates trading around the distribution of cash dividends. Our model predicts that trading volume is negatively affected by idiosyncratic risk of dividend-paying stocks. Volume is negatively affected by the systematic risk of these stocks only in the presence of transaction costs.Journal of Economic LiteratureClassification Numbers: G11, G12, H20.

Mutual funds’ strategic voting on environmental and social issues

Review of Finance 2024 28(5), 1575-1610 open access
Environmental and social (ES) funds in non-ES families must balance incorporating the stakeholders’ interests they advertise and maximizing shareholder value favored by their families. We find that these funds support ES proposals that are far from the majority threshold, while opposing them when their vote is more likely to be pivotal. This strategy results in a high average support for ES proposals, seemingly consistent with their fiduciary responsibilities, while opposing contested ES proposals. This greenwashing strategy is driven by ES funds in non-ES families who cater to institutional investors. Indeed, these funds experience lower inflows when providing low average support for ES proposals. This strategic voting is not exhibited in governance proposals, nor by ES funds in ES families or by non-ES funds in non-ES families, reinforcing the notion of strategic voting to accommodate family preferences while appearing to meet the fiduciary responsibilities of the funds.

Do Price Discreteness and Transactions Costs Affect Stock Returns? Comparing Ex‐Dividend Pricing before and after Decimalization

Journal of Finance 2003 58(6), 2611-2636 open access
By the end of January 2001, all NYSE stocks had converted their price quotations from 1/8s and 1/16s to decimals. This study examines the effect of this change in price quotations on ex‐dividend day activity. We find that abnormal ex‐dividend day returns increase in the 1/16 and decimal pricing eras, relative to the 1/8 era, which is inconsistent with microstructure explanations of ex‐day price movements. We also find that abnormal returns increase in conjunction with a May 1997 reduction in the capital gains tax rate, as they should if relative taxation of dividends and capital gains affects ex‐day pricing.

Trading in the Presence of Short-Lived Private Information: Evidence from Analyst Recommendation Changes

Journal of Financial and Quantitative Analysis 2018 53(4), 1509-1546 open access
We use a proprietary data set to test the implications of several asymmetric information models on how short-lived private information affects trading strategies and liquidity provision. Our identification rests on information acquisition before analyst recommendations are publicly announced. We provide the first empirical evidence supporting theoretical predictions that early-informed traders “sell the news” after “buying the rumor.” Further, we find distinct profit-taking patterns across different classes of institutions. Uninformed institutions, but not individuals, emerge as de facto liquidity providers to better-informed institutions. Placebo tests confirm that these trading patterns are unique to situations in which some investors have a short-lived informational advantage.

Does Socially Responsible Investing Change Firm Behavior?

Review of Finance 2023 27(6), 2057-2083 open access
Using micro-level data, we examine the behavior of socially responsible investment (SRI) funds. SRI funds select firms with lower pollution, more board diversity, higher employee satisfaction, and better workplace safety. Yet, both in the cross-section and using an exogenous shock to SRI capital, we find that SRI funds do not significantly change firm behavior. Moreover, we find little evidence that they try to impact firm behavior using shareholder proposals. Our results suggest that SRI funds are not greenwashing, but they are impact washing; they invest in a portfolio of firms with better environmental and social conduct but do not follow through on their promise of impact.

The Making of a Dealer Market: From Entry to Equilibrium in the Trading of Nasdaq Stocks

Journal of Finance 2002 57(5), 2289-2316 open access
This paper provides an analysis of the nature and evolution of a dealer market for Nasdaq stocks. Despite size differences in sample stocks, there is a surprising consistency to their trading. One dealer tends to dominate trading in a stock. Markets are concentrated and spreads are increasing in the volume and market share of the dominant dealer. Entry and exit are ubiquitous. Exiting dealers are those with very low profits and trading volume. Entering market makers fail to capture a meaningful share of trading or profits. Thus, free entry does little to improve the competitive nature of the market as entering dealers have little impact. We find, however, that for small stocks, the Nasdaq dealer market is being more competitive than the specialist market.

Financing Payouts

Journal of Financial and Quantitative Analysis 2025 60(4), 1586-1624 open access
We find that 43% of firms that make payouts also raise capital during the same year, resulting in 31% of aggregate payouts being externally financed, primarily with debt. Most financed payouts cannot be explained by payout smoothing in response to volatile earnings or investment (rather, they are the result of firms persistently setting payouts above free cash flow). In fact, 25% of aggregate payouts could not have been paid without the firms simultaneously raising capital. Profitable firms with moderate growth use debt-financed payouts to jointly manage their leverage and cash, thus highlighting the close relationship between payout and capital structure decisions.
