Private Information and High-Frequency Stochastic Volatility

We study the e®ect of privately informed traders on measured high frequency price changes and trades in asset markets. We use a standard market microstructure framework where exogenous news is captured by signals that informed agents receive. We show that the entry and exit of informed traders following the arrival of news accounts for high-frequency serial correlation in squared price changes (stochastic volatility) and grades. Because the bid-ask spread of the market specialist tends to shrink as individuals trade and reveal their information, the model also accounts for the empirical observation that high-frequency serial correlation is more pronounced in trades than in squared price changes. A calibration test of the model shows that the features of the market microstructure, without serially correlated news, accounts qualitatively for the serial correlation in the data, but predicts less persistence than is present in the data.

Delegating to a Powerless Intermediary: Does It Reduce Punishment?

Beyond the classical reasons of efficiency, commitment, the distribution of information, or incentive provision, a person may also delegate decision rights so as to avoid blame for an unpopular or immoral decision. We show that by delegating to an intermediary, a dictator facing an allocation decision can effectively shift moral responsibility onto the delegee even when doing so necessarily eliminates the possibility of a fair outcome. Dictators who choose selfishly via an intermediary are punished less and earn greater profits than those who directly choose a selfish outcome, while the intermediary is punished more.

Promises & Partnership

We examine experimentally the impact of communication on trust and cooperation. Our design admits observation of promises, lies, and beliefs. The evidence is consistent with people striving to live up to others’ expectations in order to avoid guilt, as can be modeled using psychological game theory. When players exhibit such guilt aversion, communication may influence motivation and behavior by influencing beliefs about beliefs. Promises may enhance trustworthy behavior, which is what we observe. We argue that guilt aversion may be relevant for understanding strategic interaction in variety of settings, and that it may shed light on the role of language, discussions, agreements, and social norms in these contexts.

Driving You to Drink: Do Ride-Hailing Applications Affect Restaurant and Bar Revenue?

There is recent evidence that Ride-Hailing applications reduce the number of alcohol-related motor vehicle collisions and fatalities. This paper aims to investigates how they may impact the restaurant and bar industry by estimating a difference-in-differences model across cities in California. Results suggest an average increase of $36 in quarterly per capita restaurant and bar revenue. This result is robust to model validation where the three largest cities are separately excluded from the model. Additional robustness checks do not provide any evidence that the parallel trends assumption is violated.

Political Ideology and Early Restaurant Avoidance During Covid-19

This paper studies whether political ideology affected early restaurant avoidance behavior during Covid-19 in March 2020. Early conflicting narratives about the severity of Covid-19 driven by political leaders and media outlets with liberal versus conservative views may impact the speed in which Republican and Democratic cities adopt safety measures such as avoiding dining at restaurants. I use data on seated dining rates at restaurants from OpenTable and find that cities in the United States with more Democratic voters saw faster declines in seated dining. I also find that cities with more Covid-19 cases saw faster declines in seated dining rates, but this effect is concentrated on early adopter cities. These findings have public health implications which suggest that effective public health policy should take the influence of politics on behavior into account.

Lifting the Burden

In this paper, we use a 1998 reform in the federal funding of local home-based care for the elderly in Norway to examine the effects of formal care expansion on the labor supply decisions and mobility of middle-aged children. Our main finding is a consistent and significant negative impact of formal care expansion on work absences longer than 2 weeks for the adult daughters of single elderly parents. This effect is particularly strong for daughters with no siblings, and this group is also more likely to exceed earnings thresholds after the reform. We find no impacts of the reform on daughter's mobility or parental health, and no effects on adult sons. Our results provide evidence of substitution between formal home-based care and informal care for the group that is most likely to respond to the parent's need for care � adult daughters with no siblings to share the burden of parental care. These results also highlight the importance of labor market institutions that provide flexibility in enabling women to balance home and work responsibilities.

Adapting to Climate Change: The Remarkable Decline in the US Temperature-Mortality Relationship over the Twentieth Century

This paper examines the temperature-mortality relationship over the course of the twentieth-century United States both for its own interest and to identify potentially useful adaptations for coming decades. There are three primary findings. First, the mortality impact of days with mean temperature exceeding 807F declined by 75 percent. Almost the entire decline occurred after 1960. Second, the diffusion of residential air conditioning explains essentially the entire decline in hot day–related fatalities. Third, using Dubin and McFadden’s discrete continuous model, the present value of US consumer surplus from the introduction of residential air conditioning is estimated to be $85– $185 billion (2012 dollars).

The Economic Impacts of Climate Change: Evidence from Agricultural Output and Random Fluctuations in Weather: Comment

In a series of studies employing a variety of approaches, we have found that the potential impact of climate change on US agriculture is likely negative. Deschênes and Greenstone (2007) report dramatically different results based on regressions of agricultural profits and yields on weather variables. The divergence is explained by (1) missing and incorrect weather and climate data in their study; (2) their use of older climate change projections rather than the more recent and less optimistic projections from the Fourth Assessment Report; and (3) difficulties in their profit measure due to the confounding effects of storage.

The Algebra of Assortative Encounters and the Evolution of Cooperation

This paper explores the way that assortative matching can maintain cooperative behavior under evolutionary dynamics.

A Test for Efficiency in the Supply of Public Goods

This paper conducts an empirical test of whether local governments spend more or less than a Pareto optimal amount on local public goods. Our procedure is to check whether the Samuelson first order conditions ) for efficient provision of public goods are satisfied.

Economics in a Family Way

This paper is an advertisement for some facts and ideas that I think likely to lead to a richer theory of the economics of the family. The discussion references many papers from anthropology and biology. Because of the intimate connection between the family and reproduction, it should not be surprising that there is much to be learned about the economics of the family from the study of evolutionary biology. Given the increased prevalence in recent decades of unwed parenthood, divorce with sequential monogamy, and ``non-traditional'' family arrangements, it seems that anthropological studies of alternative family structures would help us to understand our own.

Agricultural pesticide use and adverse birth outcomes in the San Joaquin Valley of California.

Virtually all agricultural communities worldwide are exposed to agricultural pesticides. Yet, the health consequences of such exposure are poorly understood, and the scientific literature remains ambiguous. Using individual birth and demographic characteristics for over 500 000 birth observations between 1997-2011 in the agriculturally dominated San Joaquin Valley, California, we statistically investigate if residential agricultural pesticide exposure during gestation, by trimester, and by toxicity influences birth weight, gestational length, or birth abnormalities. Overall, our analysis indicates that agricultural pesticide exposure increases adverse birth outcomes by 5-9%, but only among the population exposed to very high quantities of pesticides (e.g., top 5th percentile, i.e., ~4200 kg applied over gestation). Thus, policies and interventions targeting the extreme right tail of the pesticide distribution near human habitation could largely eliminate the adverse birth outcomes associated with agricultural pesticide exposure documented in this study.The health consequences of exposure to pesticides are uncertain and subject to much debate. Here, the effect of exposure during pregnancy is investigated in an agriculturally dominated residential area, showing that an increase in adverse birth outcomes is observed with very high levels of pesticide exposure.
