Complaints and Disenrollment at a Health Maintenance Organization

Two options for dissatisfied customers are to voice their grievances or to stop doing business with the offending organization. The choice may be influenced by buyer loyalty. Data for a major Health Maintenance Organization are used to explore the empirical relationship among complaint (voice), disenrollment (exit), and time-in-plan (loyalty). Voice and exit are often used together. Compared to non-complainers, those who register medical complaints are four and one-half times more likely to leave the plan voluntarily. Time-in-plan reduces the likelihood of both voluntary and involuntary disenrollment.     

CAN SOFT DRINK TAXES REDUCE POPULATION WEIGHT?

Soft drink consumption has been hypothesized as one of the major factors in the growing rates of obesity in the United States. Nearly two-thirds of all states currently tax soft drinks using excise taxes, sales taxes, or special exceptions to food exemptions from sales taxes to reduce consumption of this product, raise revenue, and improve public health. In this paper, we evaluate the impact of changes in state soft drink taxes on body mass index (BMI), obesity, and overweight. Our results suggest that soft drink taxes influence BMI, but that the impact is small in magnitude. ( JEL I18, H75)     

A New Data Set on Monetary Policy: The Economic Forecasts of Individual Members of the FOMC

This paper describes a new data set of the forecasts of output growth, inflation, and unemployment prepared by individual members of the Federal Open Market Committee. The paper discusses the scope of the data set, possibilities for extending it, and some potential uses. It offers a preliminary examination of some of the cross‐sectional features of the data.     

Why Does the Law Matter? Investor Protection and Its Effects on Investment,Finance, and Growth

Investor protection is associated with greater investment sensitivity to q and lower investment sensitivity to cash flow. Finance plays a role in causing these effects; in countries with strong investor protection, external finance increases more strongly with q, and declines more strongly with cash flow. We further find that q and cash flow sensitivities are associated with ex post investment efficiency; investment predicts growth and profits more strongly in countries with greater q sensitivities and lower cash flow sensitivities. The paper's findings are broadly consistent with investor protection promoting accurate share prices, reducing financial constraints, and encouraging efficient investment.     

Concern with Immediate Consequences Magnifies the Impact of Compulsive Buying Tendencies on College Students' Credit Card Debt

This research examines whether temporal orientation moderates the impact of compulsive buying tendencies (CBT) on credit card debt. Participants completed the consideration of future consequences scale, a compulsive buying scale, and reported their credit card debt. Results revealed that CBT mediated the relationship between concern with immediate consequences and credit card debt, and high concern with immediate consequences magnified the impact of CBT on credit card debt. This suggests that compulsive buyers who focus on maximizing immediate consequences are at a much higher risk of building up significant amounts of credit card debt.     

Volatility increases Subsequent to NYSE and AMEX Stock Splits

The post-split increase in daily returns volatility is less for AMEX stocks than for NYSE stocks. The exchange trading location is a significant factor in explaining the volatility shift even after stock price and firm size are considered. Furthermore, when measured on a weekly basis, there is no increase in AMEX stocks' returns volatility. These results suggest that measurement errors created by bid-ask spreads and the 1/8 effect, and also one or more of the elements that make the NYSE different from the AMEX, explain why the estimated volatility of daily stock returns increases after the ex split date.
