Presidential Address: Social Transmission Bias in Economics and Finance

DAVID HIRSHLEIFER
I discuss a new intellectual paradigm, social economics and finance—the study of the social processes that shape economic thinking and behavior. This emerging field recognizes that people observe and talk to each other. A key, underexploited building block of social economics and finance is social transmission bias: systematic directional shift in signals or ideas induced by social transactions. I use five “fables” (models) to illustrate the novelty and scope of the transmission bias approach, and offer several emergent themes. For example, social transmission bias compounds recursively, which can help explain booms, bubbles, return anomalies, and swings in economic sentiment.
Good Day Sunshine: Stock Returns and the Weather

AbstractPsychological evidence and casual intuition predict that sunny weather is associated with upbeat mood. This paper examines the relationship between morning sunshine in the city of a country's leading stock exchange and daily market index returns across 26 countries from 1982 to 1997. Sunshine is strongly significantly correlated with stock returns. After controlling for sunshine, rain and snow are unrelated to returns. Substantial use of weather‐based strategies was optimal for a trader with very low transactions costs. However, because these strategies involve frequent trades, fairly modest costs eliminate the gains. These findings are difficult to reconcile with fully rational price setting.
The Causal Effect of Limits to Arbitrage on Asset Pricing Anomalies

YONGQIANG CHU, DAVID HIRSHLEIFER, LIANG MA
We examine the causal effect of limits to arbitrage on 11 well‐known asset pricing anomalies using the pilot program of Regulation SHO, which relaxed short‐sale constraints for a quasi‐random set of pilot stocks, as a natural experiment. We find that the anomalies became weaker on portfolios constructed with pilot stocks during the pilot period. The pilot program reduced the combined anomaly long–short portfolio returns by 72 basis points per month, a difference that survives risk adjustment with standard factor models. The effect comes only from the short legs of the anomaly portfolios.

War Discourse and the Cross Section of Expected Stock Returns

A war‐related factor model derived from textual analysis of media news reports explains the cross section of expected stock returns. Using a semisupervised topic model to extract discourse topics from 7,000,000
New York Times
stories spanning 160 years, the war factor predicts the cross section of returns across test assets derived from both traditional and machine learning construction techniques, and spanning 138 anomalies. Our findings are consistent with assets that are good hedges for war risk receiving lower risk premia, or with assets that are more positively sensitive to war prospects being more overvalued. The return premium on the war factor is incremental to standard effects.
Investor Psychology and Security Market Under‐ and Overreactions

Kent Daniel, David Hirshleifer, Avanidhar Subrahmanyam
We propose a theory of securities market under‐ and overreactions based on two well‐known psychological biases: investor overconfidence about the precision of private information; and biased self‐attribution, which causes asymmetric shifts in investors' confidence as a function of their investment outcomes. We show that overconfidence implies negative long‐lag autocorrelations, excess volatility, and, when managerial actions are correlated with stock mispricing, public‐event‐based return predictability. Biased self‐attribution adds positive short‐lag autocorrelations (“momentum”), short‐run earnings “drift,” but negative correlation between future returns and long‐term past stock market and accounting performance. The theory also offers several untested implications and implications for corporate financial policy.

Visibility Bias in the Transmission of Consumption Beliefs and Undersaving
Published: 4/4/2023, Volume: 78, Issue: 3 | DOI: 10.1111/jofi.13223 | Cited by: 14
BING HAN, DAVID HIRSHLEIFER, JOHAN WALDEN
We model visibility bias in the social transmission of consumption behavior. When consumption is more salient than nonconsumption, people perceive that others are consuming heavily, and infer that future prospects are favorable. This increases aggregate consumption in a positive feedback loop. A distinctive implication is that disclosure policy interventions can ameliorate undersaving. In contrast with wealth‐signaling models, information asymmetry about wealthreducesoverconsumption. The model predicts that saving is influenced by social connectedness, observation biases, and demographic structure, and provides new insight into savings rates. These predictions are distinct from other common models of consumption distortions.
Security Analysis and Trading Patterns When Some Investors Receive Information Before Others

In existing models of information acquisition, all informed investors receive their information at the same time. This article analyzes trading behavior and equilibrium information acquisition when some investors receive common private information before others. The model implies that, under some conditions, investors will focus only on a subset of securities (“herding”), while neglecting other securities with identical exogenous characteristics. In addition, the model is consistent with empirical correlations that are suggestive of oft‐cited trading strategies such as profit taking (short‐term position reversal) and following the leader (mimicking earlier trades).
Overconfidence, Arbitrage, and Equilibrium Asset Pricing

Kent D. Daniel, David Hirshleifer, Avanidhar Subrahmanyam
This paper offers a model in which asset prices reflect both covariance risk and misperceptions of firms' prospects, and in which arbitrageurs trade against mispricing. In equilibrium, expected returns are linearly related to both risk and mispricing measures (e.g., fundamental/price ratios). With many securities, mispricing of idiosyncratic value components diminishes but systematic mispricing does not. The theory offers untested empirical implications about volume, volatility, fundamental/price ratios, and mean returns, and is consistent with several empirical findings. These include the ability of fundamental/price ratios and market value to forecast returns, and the domination of beta by these variables in some studies.
Driven to Distraction: Extraneous Events and Underreaction to Earnings News

Recent studies propose that limited investor attention causes market underreactions. This paper directly tests this explanation by measuring the information load faced by investors. The investor distraction hypothesis holds that extraneous news inhibits market reactions to relevant news. We find that the immediate price and volume reaction to a firm's earnings surprise is much weaker, and post‐announcement drift much stronger, when a greater number of same‐day earnings announcements are made by other firms. We evaluate the economic importance of distraction effects through a trading strategy, which yields substantial alphas. Industry‐unrelated news and large earnings surprises have a stronger distracting effect.
Are Overconfident CEOs Better Innovators?

Previous empirical work on adverse consequences of CEO overconfidence raises the question of why firms hire overconfident managers. Theoretical research suggests a reason: overconfidence can benefit shareholders by increasing investment in risky projects. Using options‐ and press‐based proxies for CEO overconfidence, we find that over the 1993–2003 period, firms with overconfident CEOs have greater return volatility, invest more in innovation, obtain more patents and patent citations, and achieve greater innovative success for given research and development expenditures. However, overconfident managers achieve greater innovation only in innovative industries. Our findings suggest that overconfidence helps CEOs exploit innovative growth opportunities.
Naïve Buying Diversification and Narrow Framing by Individual Investors

We provide the first tests to distinguish whether individual investors equally balance their overall portfolios (naïve portfolio diversification, NPD) or, in contrast, equally balance the values of same‐day purchases of multiple assets (naïve buying diversification, NBD). We find NBD in purchases of multiple stocks, and in mixed purchases of individual stocks and funds. In contrast, there is little evidence of NPD. Evidence suggests that NBD arises due to stock picking behavior and neglect of diversification. These findings suggest that behavioral finance theory should incorporate transaction, as well as portfolio, framing.
Does Investor Misvaluation Drive the Takeover Market?

MING DONG, DAVID HIRSHLEIFER, SCOTT RICHARDSON, SIEW HONG TEOH
This paper uses pre‐offer market valuations to evaluate the misvaluation and Q theories of takeovers. Bidder and target valuations (price‐to‐book, or price‐to‐residual‐income‐model‐value) are related to means of payment, mode of acquisition, premia, target hostility, offer success, and bidder and target announcement‐period returns. The evidence is broadly consistent with both hypotheses. The evidence for the Q hypothesis is stronger in the pre‐1990 period than in the 1990–2000 period, whereas the evidence for the misvaluation hypothesis is stronger in the 1990–2000 period than in the pre‐1990 period.

We show that retail trading activity has a positive effect on the volatility of stock returns, which suggests that retail investors behave as noise traders. To identify this effect, we use a reform of the French stock market that raises the relative cost of speculative trading for retail investors. The daily return volatility of the stocks affected by the reform falls by 20 basis points (a quarter of the sample standard deviation of the return volatility) relative to other stocks. For affected stocks, we also find a significant decrease in the magnitude of return reversals and the price impact of trades.
Political Connections and Allocative Distortions

Exploiting a unique institutional setting in Korea, this paper documents that politicians can increase the amount of government resources allocated through their social networks to the benefit of private firms connected to these networks. After winning the election, the new president appoints members of his networks as CEOs of state‐owned firms that act as intermediaries in allocating government contracts to private firms. In turn, these state firms allocate significantly more procurement contracts to private firms with a CEO from the same network. Contracts allocated to connected private firms are executed systematically worse and exhibit more frequent cost increases through renegotiations.

I study incentives received by outside directors in Fortune 500 firms from compensation, replacement, and the opportunity to obtain other directorships. Previous research has only shown these relations to apply under limited circumstances such as financial distress. Together these incentive mechanisms provide directors with wealth increases of approximately 11 cents per $1,000 rise in firm value. Although smaller than the performance sensitivities of CEOs, outside directors' incentives imply a change in wealth of about $285,000 for a 1 standard deviation (SD) change in typical firm performance. Cross‐sectional patterns of director equity awards conform to agency and financial theories.
Heterogeneous Beliefs, Speculation, and the Equity Premium

ALEXANDER DAVID
Agents with heterogeneous beliefs about fundamental growth do not share risks perfectly but instead speculate with each other on the relative accuracy of their models' predictions. They face the risk that market prices move more in line with the trading models of competing agents than with their own. Less risk‐averse agents speculate more aggressively and demand higher risk premiums. My calibrated model generates countercyclical consumption volatility, earnings forecast dispersion, and cross‐sectional consumption dispersion. With a risk aversion coefficient less than one, agents' speculation causes half the observed equity premium and lowers the riskless rate by about 1%.

The Term Structure of Interest Rates in a Partially Observable Economy

DAVID FELDMAN
This paper investigates the term structure of interest rates in a multiperiod production and exchange economy with incomplete information. Unable to observe their stochastic investment opportunities, investors engage in dynamic Bayesian inference. This results in the endogenous identification of a more complex production function which generates a richer term structure, resembling the one that actual market prices imply. In addition, this paper introduces a characteristic function of the term structure and demonstrates that, in contrast with a fully observable economy, the widely investigated expectations hypothesis holds true only if interest rates are nonstochastic.
Good Timing: CEO Stock Option Awards and Company News Announcements

DAVID YERMACK
This article analyzes the timing of CEO stock option awards, as a method of investigating corporate managers' influence over the terms of their own compensation. In a sample of 620 stock option awards to CEOs of Fortune 500 companies between 1992 and 1994, I find that the timing of awards coincides with favorable movements in company stock prices. Patterns of companies' quarterly earnings announcements are consistent with an interpretation that CEOs receive stock option awards shortly before favorable corporate news. I evaluate and reject several alternative explanations of the results, including insider trading and the manipulation of news announcement dates.
Testing the Efficiency of the Canadian‐U.S. Exchange Market under the Assumption of no Risk Premium

DAVID LONGWORTH
The efficiency of the Canadian‐U.S. exchange market for the current float is examined more extensively than previously. Semi‐strong‐form tests which admit the lagged spot rate as a predictor are considered in addition to the standard weak‐form test. These stronger tests reject the joint null hypothesis of an efficient exchange market and no risk premium for the period ending in October 1976, although not for the entire period. For almost every year the current spot rate provided a better forecast of the future spot rate than did the current forward rate.
A Theoretical Model for Valuing Preferred Stock

DAVID EMANUEL
This paper develops a model of preferred stock value which includes the possibility of dividends on the preferred stock being omitted. The analytical framework used is based on the option‐hedging methodology of Black and Scholes. Precise valuation formulae are obtained for cumulative and noncumulative preferred stock in a variety of contexts. The values obtained are quite different from those for either riskless or risky perpetual bonds, which have previously been proposed as being similar to preferred stock.
Can Unemployment Insurance Spur Entrepreneurial Activity? Evidence from France

We evaluate the effect of downside insurance on self‐employment. We exploit a large‐scale reform of French unemployment benefits that insured unemployed workers starting businesses. The reform significantly increased firm creation without decreasing the quality of new entrants. Firms started postreform were initially smaller, but their employment growth, productivity, and survival rates are similar to those prereform. New entrepreneurs' characteristics and expectations are also similar. Finally, jobs created by new entrants crowd out employment in incumbent firms almost one‐for‐one, but have a higher productivity than incumbents. These results highlight the benefits of encouraging experimentation by lowering barriers to entry.
Housing Collateral and Entrepreneurship

MARTIN C. SCHMALZ, DAVID A. SRAER, DAVID THESMAR
We show that collateral constraints restrict firm entry and postentry growth, using French administrative data and cross‐sectional variation in local house‐price appreciation as shocks to collateral values. We control for local demand shocks by comparing treated homeowners to controls in the same region that do not experience collateral shocks: renters and homeowners with an outstanding mortgage, who (in France) cannot take out a second mortgage. In both comparisons, an increase in collateral value leads to a higher probability of becoming an entrepreneur. Conditional on entry, treated entrepreneurs use more debt, start larger firms, and remain larger in the long run.

This paper values a contingent claim to discrete stochastic cash flows generated by a Poisson arrival process with a randomly varying intensity parameter. In the most general case, both the size and the arrival intensity of cash flows may correlate wih state variables in a continuous time economy. Assuming the conditions of an intertemporal capital aset pricing model, solutions for the value of the contingent claim can be found using various techniques. The paper suggests immediate applications to the valuation of insurance contracts, the decision to build a firm with unknown future investment opportunities, and the pricing of mortgage‐backed securities.

I present a model that endogenizes the extent to which savings are intermediated through banks or capital markets, and derive implications for corporate finance, household finance, banking, and the size of the financial sector. I then present a number of facts that are broadly consistent with the theory and examine a variety of alternative explanations of my findings.

DAVID A. CHAPMAN
This article tests a simple consumption‐based asset pricing model by approximating the true asset pricing kernel using low‐order orthonormal polynomials based on the model's state variables. Approximated kernels based solely on next period's consumption growth are not rejected by overall measures of model fit, but they produce statistically and economically large pricing errors. Approximated kernels based on two quarters of future consumption growth and technology shocks have substantially improved overall fit. In particular, the best of these kernels are capable of eliminating the small firm effect.

DAVID C. CICERO
I identify three option exercise strategies executives engage in, including (i) exercising with cash and immediately selling the shares, (ii) exercising with cash and holding the shares, and (iii) delivering some shares to the company to cover the exercise costs and holding the remaining shares. Stock price patterns suggest executives manipulate option exercises. They use private information to increase the profitability of all three strategies, and likely backdated some exercise dates in the pre‐Sarbanes‐Oxley period to enhance the profitability of the latter two strategies, where the executive's company is the only counterparty. Backdating is associated with reporting of internal control weaknesses.
