Caught on tape: Institutional trading,stock returns,and earnings announcements

Many questions about institutional trading can only be answered if one tracks high-frequency changes in institutional ownership. In the United States, however, institutions are only required to report their ownership quarterly in 13-F filings. We infer daily institutional trading behavior from the “tape”, the Transactions and Quotes database of the New York Stock Exchange, using a sophisticated method that best predicts quarterly 13-F data from trades of different sizes. We find that daily institutional trades are highly persistent and respond positively to recent daily returns but negatively to longer-term past daily returns. Institutional trades, particularly sells, appear to generate short-term losses—possibly reflecting institutional demand for liquidity—but longer-term profits. One source of these profits is that institutions anticipate both earnings surprises and post-earnings announcement drift. These results are different from those obtained using a standard size cutoff rule for institutional trades.     

Entrepreneurship and the taste for discrimination

This paper analyzes the connection between discrimination and entrepreneurship. We contend that the entrepreneur is the central mechanism through which inefficiencies associated with discrimination are competed away. In addition to illuminating the mechanism through which existing discrimination tends to be eliminated, we also consider the more difficult case of consumer discrimination. The standard assumption is that consumer discrimination will not be competed away through market forces. In contrast, we find that entrepreneurs can correct the inefficiencies associated with this form of discrimination by influencing the costs and benefits associated with consumer discrimination. We empirically analyze the integration of black players in Major League Baseball to illustrate our theoretical arguments regarding entrepreneurship and consumer discrimination.     

The Hot–Cold Decision Triangle: A framework for healthier choices

People often behave in ways that are clearly detrimental to their health. We review representative research on unhealthy behaviors within a parsimonious framework, the Hot-Cold Decision Triangle. Through this framework, we describe how when people embrace colder state reasoning??instead of risking the pitfalls of heuristics and visceral reactions??they are more likely to behave healthily. We also illustrate how some heuristics and visceral urges can be leveraged to encourage healthier choices. We conclude by discussing unexplored research directions, as well as substantive implications for individuals, marketers, and policymakers.     

The State of Business Ethics in Israel: A Light Unto the Nations?

Whether the nation of Israel has become a “light unto the nations” in terms of ethical behavior among its business community remains in doubt. To examine the current state of business ethics in Israel, the study examines the following: (1) the extent of business ethics education in Israel; (2) the existence of formal corporate ethics program elements based on an annual survey of over 50 large Israeli corporations conducted over 5 years (2006–2010); and (3) perceptions of the state of business ethics based on interviews conducted with 22 senior Israeli corporate executives. In general, and particularly as a young country, Israel might be considered to have made great improvements in the state of business ethics over the years. In terms of business ethics education, the vast majority of universities and colleges offer at least an elective course in business ethics. In terms of formal business ethics program elements, many large companies now have a code of ethics, and over time continue to add additional elements. Most respondents believed they worked in ethical firms. Despite these developments, however, there appears to be significant room for improvement, particularly in terms of issues like: nepotism/favoritism; discrimination; confidentiality; treatment of customers; advertising; competitive intelligence; whistle-blowing; worker health and safety; and the protection of the environment. When compared with the U.S. or Europe, most believed that Israeli firms and their agents were not as ethical in business. A number of reasons were suggested that might be affecting the state of business ethics in Israel. A series of recommendations were also provided on how firms can better encourage an ethical corporate culture. The paper concludes with its limitations.     

Labor market dynamics over the business cycle: evidence from Markov switching models

This paper explores the evolution of the U.S. labor market across the business cycle and specifically the relationship between the unemployment rate and the average duration of unemployment. Labor market recoveries have long been thought of as lagging recoveries in broad economic activity. In particular, the unemployment rate peaks several months after official business cycle troughs and the average duration of unemployment lags further behind. Using estimates from Markov switching models of the unemployment rate, average duration of unemployment, jobless claims, and the exhaustion rate of regular unemployment insurance, this paper dates contractionary and expansionary phases of various aspects of the labor market and their relationship to the official phases of the business cycle. Evidence from these models suggests that inflows into unemployment recover almost contemporaneously with broad economic activity, while outflows recover almost a year after the end of official recessions. The differential timing in the recoveries of unemployment inflows and outflows, which is not a characteristic of most macro models of the labor market, accounts for the observed pattern between the unemployment rate and average duration of unemployment. Finally, when comparing the phases of the labor market to periods where Congress extends unemployment insurance benefits, it appears that policymakers target periods where the job finding rate is low, rather than periods where the stock of unemployed workers is high.
