Do Demand Curves for Small Stocks Slope Down?

Stocks added to the S&P 500 generally experience positive abnormal returns following the announcement. Several competing explanations exist for this reaction, but small sample sizes and other issues make it difficult to distinguish among them. We examine this subject using the small‐cap Russell 2000 index, which has several advantages over the S&P 500 in this context. Our primary finding is that stocks added to or deleted from the Russell 2000 experience significant changes in stock price and trading volume, but the effect is transitory. The results support the price pressure hypothesis.     

Why are population flows so persistent?

A neoclassical model of local growth is developed by integrating the static equilibrium underlying compensating differential theory as the steady state of a neoclassical growth model. Numerical results show that even very small frictions to labor and capital mobility along with small changes in local productivity or local quality of life suffice to cause highly persistent population flows. Wages and house prices, in contrast, jump most of the way to their new steady state. The model suggests that cross-sectional regressions of local population growth can help to identify past and present changes in the determinants of representative-agent welfare. More generally, it provides a framework for interpreting observed local growth rates.     

Determinants of tourists' expenditure at mass participant sport events: a five-year analysis

Using the five-year data of a US running event (N?=?9380), this study examined key determinants of tourists' expenditure in a mass participant sport event. Economic constraint, travel-related, socio-demographic, and sport-related facets were integrated into the expenditure model while considering changes in tourism prices. The proposed four-facet model provides a broader framework for event organisers and destination marketers in evaluating what factors determine participants' spending behaviours while at the destination, thereby maximising the potential economic benefits of hosting a participant sport event.     

A simple method for estimating preference parameters for individuals

This paper demonstrates a method for estimating logit choice models for small sample data, including single individuals, that is computationally simpler and relies on weaker prior distributional assumptions compared to hierarchical Bayes estimation. Using Monte Carlo simulations and online discrete choice experiments, we show how this method is particularly well suited to estimating values of choice model parameters from small sample choice data, thus opening this area to the application of choice modeling. For larger sample sizes of approximately 100–200 respondents, preference distribution recovery is similar to hierarchical Bayes estimation of mixed logit models for the examples we demonstrate. We discuss three approaches for specifying the conjugate priors required for the method: specifying priors based on existing or projected market shares of products, specifying a flat prior on the choice alternatives in a discrete choice experiment, or adopting an empirical Bayes approach where the prior choice probabilities are taken to be the average choice probabilities observed in a discrete choice experiment. We show that for small sample data, the relative weighting of the prior during estimation is an important consideration, and we present an automated method for selecting the weight based on a predictive scoring rule.     

Communication complexity and stability of equilibria in economies and games

The theory of decentralized allocation mechanisms introduced by Leonid Hurwicz enabled economists to analyze the implications of requiring an allocation mechanism to perform well over a range of possible economic environments. One of the earliest major results in this theory was the formalization and proof of Hayek’s famous assertion that the competitive market mechanism minimizes the communication needed to achieve Pareto efficient allocations. The informational efficiency theorem spawned a large literature on communication complexity in allocation mechanisms. This paper provides an exposition of some results on the communication required to make equilibria locally stable, and the possibility of eliciting the required communication in allocation mechanisms and games.     

MATURITY AND REFUNDING EFFECTS ON TREASURY-BOND FUTURES PRICE VARIANCE

Both Samuelson's maturity hypothesis and the Anderson-Danthine state variable hypothesis are tested in this study of the variance of Treasury-bond futures prices. Both maturity and the quarterly refunding of Treasury debt have statistically and economically significant effects on futures price variance. The evidence for a monotonic maturity effect is highly statistically significant and robust to changes in model specification. The quarterly refunding is less statistically significant, and it is not clear whether the greatest effect is in the auction week or two weeks thereafter. Economically, these two predictable effects are of greater importance than a change in the discount rate.     

What Will Consumers Pay for Social Product Features?

The importance of ethical consumerism to many companies worldwide has increased dramatically in recent years. Ethical consumerism encompasses the importance of non-traditional and social components of a company's products and business process to strategic success – such as environmental protectionism, child labor practices and so on. The present paper utilizes a random utility theoretic experimental design to provide estimates of the relative value selected consumers place on the social features of products.
