ILLICIT DRUG USE, ABSENTEEISM, AND EARNINGS AT SIX U.S. WORKSITES

Considerable national attention has focused recently on the adverse consequences of illicit drug use. While several studies estimate the relationship between illicit drug use and wages, the findings are inconsistent. Surprisingly, some researchers identify a positive and statistically significant relationship between wages and drug use for young adults. Motivated by this counter-intuitive finding, this paper compiles unique data on employees at six worksites in order to explore the relationships among drug use, wages, and absenteeism. Using various measures of current and lifetime drug use and accounting for alcohol-use comorbidity, the authors find predominantly insignificant relationships (both direct and indirect) between drug use and both wages and absenteeism, regardless of gender.     

Getting Out Early: An Analysis of Market Making Activity at the Recommending Analyst's Firm

This paper examines trading volume for Nasdaq market makers around analyst recommendation changes issued by an analyst at the same firm. Using Nasdaq PostData, we find a disproportionate increase in market making volume associated with the firm's recommendation changes and evidence of elevated sell volume at the recommending analyst's firm in the 2 days preceding a downgrade. The implications are that the information source matters in determining the placement of trades and that the issuing analyst's firm appears to be rewarded for prereleasing information through increased volume. These findings constitute new evidence of compensation for research production through the market making channel.     

Blurring Firm Boundaries: The Role of Venture Capital in Strategic Alliances

This study documents a new value-added role of venture capitalists and addresses important questions about how resources are combined to create firms. As part of the nexus of contracts surrounding a firm, strategic alliances can be viewed as relational contracts that blur firm boundaries. This paper provides evidence that alliances are more frequent among companies sharing a common venture capitalist. The effect is concentrated in alliances in which contracting problems are more pronounced, consistent with venture capitalists utilizing informational and other advantages in providing resources to firms. Further, these alliances improve the probability of exit for venture-backed firms.     

Defined Contribution Pension Plans: Sticky or Discerning Money?

Participants in defined contribution (DC) retirement plans rarely adjust their portfolio allocations, suggesting that their investment choices and consequent money flows are sticky and not discerning. However, participants’ inertia could be offset by DC plan sponsors, who adjust the plan's investment options. We examine these countervailing influences on flows into U.S. mutual funds. We find that flows into funds from DC assets are more volatile and exhibit more performance sensitivity than non‐DC flows, primarily due to adjustments to the investment options by the plan sponsors. Thus, DC retirement money is less sticky and more discerning than non‐DC money.     

Time‐Varying Fund Manager Skill

We propose a new definition of skill as general cognitive ability to pick stocks or time the market. We find evidence for stock picking in booms and market timing in recessions. Moreover, the same fund managers that pick stocks well in expansions also time the market well in recessions. These fund managers significantly outperform other funds and passive benchmarks. Our results suggest a new measure of managerial ability that weighs a fund's market timing more in recessions and stock picking more in booms. The measure displays more persistence than either market timing or stock picking alone and predicts fund performance.     

Empirical Testing of Real Option-Pricing Models

This research is the first to examine the empirical predictions of a real option-pricing model using a large sample of market prices. We find empirical support for a model that incorporates the option to wait to develop land. The option model has explanatory power for predicting transactions prices over and above the intrinsic value. Market prices reflect a premium for the option to wait to invest that has a mean value of 6% in our sample. We also estimate implied standard deviations for individual commercial property prices ranging from 18 to 28% per year.     

Revealed Preference Analysis of Characteristics Models

Characteristics models have been found to be useful in many areas of economics. However, their empirical implementation tends to rely heavily on functional form assumptions. In this paper we develop a revealed preference approach to characteristics models. We derive the necessary and sufficient empirical conditions under which data on the market behaviour of heterogeneous, price-taking consumers are non-parametrically consistent with the consumer characteristics model. Where these conditions hold, we show how information may be recovered on individual consumers' marginal valuations of product attributes. In some cases, marginal valuations are point identified, and in other cases, we can only recover bounds. Where the conditions fail, we highlight the role which the introduction of unobserved product attributes can play in rationalizing the data. We implement these ideas using consumer panel data on the Danish milk market.     

Reciprocated community support and small town - small business success

This paper presents an empirical test of the significance of reciprocated community support, in contrast with traditional economic factors and unilateral support, in the success of small businesses in small towns. The central hypothesis is that entrepreneurs who make non-market contributions to their community and whose community supports them, are more likely to consider their businesses to be successful. Logistic regression is used to analyse survey data from over 800 small businesses in 30 small towns of the state of Iowa (USA). The authors found that the interaction effect of an entrepreneur's service to the community, reciprocated by community support of the business, is the single most significant determinant of business success among dozens of indicators and characteristics of the respondent, the business, and the small towns in the sample. In addition, it was found that business people who feel successful expect to expand. These findings are relevant to rural development. The expansion of existing businesses is an important component of regional job growth.
