A measure of alienation from the marketplace

For the purpose of equipping researchers in marketing with a more sophisticated method to measure alienation in a marketing context, the authors have constructed and initially tested an alienation from the marketplace index. Alienation is defined in terms of Melvin Seeman's (1959) five basic variants of alienation: powerlessness, meaninglessness, normlessness, social isolation, and self-estrangement. After pretesting, two questions per variant of alienation remained as the operational measures of alienation from the marketplace. These questions focused specifically on marketing phenomenon. Test-retest reliability was tested with 35 paired observations. Validity was checked with survey data from 140 households. In terms of face or content validity, the questions met the criterion of “looking as if” they should indicate the corresponding dimensions of alienation. Correlations between the marketplace alienation items and a measure of general alienation established concurrent validity. The authors propose that the use of the marketplace alienation index in studies involving those who are affected by our country's business climate may prove useful. For example, one would hypothesize that increasing alienation from the marketplace would be associated with support of consumerist goals, or even of additional government legislation to control problems that the individual feels is uncontrollable by him because of the bigness and indifference of modern day enterprise.

Disability Risk Management and Postinjury Employment of Workers With Back Pain

We analyze the outcomes of occupational back pain among four large employers that use one or more of the following disability management practices: aggressive return to work, claims management, medical management, or time‐limited job accommodations. Outcomes measured at 6 and 12 months postonset include: duration of initial work absence and the probability of returning to stable employment. Employment outcomes are better in firms with more proactive return‐to‐work policies than in firms with more restrictive policies. We devise a statistical test for attrition bias and conclude that sample attrition does not significantly alter our results.     

Reinforcement versus balance response in sequential choice

Psychologists often explore the impact of one act on a subsequent related act. With an eye to the marketing literature, this paper explores two properties of sequential choices that involve the resolution of competing goals. Reinforcement occurs when the goals driving the first choice are made stronger by that choice and result in a congruent subsequent choice. Balance occurs when the first choice satisfies or extinguishes the goals that led to the original decision, producing an incongruent subsequent choice. This review examines a number of psychological frameworks that account for reinforcement or balance responses in sequential choice and identifies theoretically relevant moderating variables that lead to either response.     

Faster Implied Volatilities via the Implicit Function Theorem

We present a faster, more accurate technique for estimating implied volatility using the standard partial derivatives of the Black‐Scholes option‐pricing formula. Beside Newton‐Raphson and slower approximation methods, this technique is the first to provide an error tolerance, which is essential for practical application. All existing noniterative approximation methods do not provide error tolerances and have the potential for large errors.     

Exploring VCR use as a leisure activity

On the basis of a uses‐and‐gratifications perspective, this exploratory study examined the TV viewing and VCR use of a sample of 119 households with VCRs. The instrument developed for use in this study consisted of a TV and VCR diary in which respondents recorded a variety of information related to each viewing (or recording) occasion for 1 week. The results suggest that although the ability to manipulate the broadcast schedule was a valued feature of the VCR, VCR use merely enhanced established patterns of TV viewing rather than significantly altered TV viewing or leisure behavior. The playback function of the VCR represented a primarily solitary activity pursued for entertainment and relaxation. Watching rented movies represented a primarily social activity pursued for entertainment, relaxation, and companionship. An equal number of television programs were viewed alone as were viewed with others.     

Summary of Results of Survey of Seminar Attendees

Abstract

The Society of Actuaries undertook a three-phase research project on mortality improvement in the three NAFTA countries: Canada, Mexico, and the U.S. Phase 1 consisted of a literature review of papers on projecting mortality levels in the future and a study of the trend in mortality improvement during this century. Phase 2 consisted of a discussion of different facets of modeling mortality rates at a seminar attended by 79 experts (actuaries, demographers, economists, and medical researchers) representing different countries. The last session of the seminar consisted of the completion of a survey by the attendees to obtain input for Phase 3, which would analyze the impact of mortality improvement on the social security system of each country. This paper summarizes the results of the survey.

The survey results illustrate the difficulty in forecasting mortality levels, because the effects of many factors that could have significant impact on mortality rates are unknown. This suggests the need for dynamic forecasting, which allows for the possibility of random shocks. A majority of the survey respondents believe that stochastic forecasting models, despite their complexity, have significant potential to add value. Respondents also believe that both historical data and cause-specific mortality forecasts are useful as input and also in validating forecasts of the aggregate levels of mortality. The challenge is to develop more sophisticated forecasting models to produce results that are relatively easy to interpret and to communicate these results to the desired audiences, including the public and policymakers.

The survey results suggest that the aggregate effect of lifestyle changes, medical advances, diseases, catastrophe, and physical environmental changes is an increase in life span. However, there is much uncertainty about the future. Respondents expect that beyond the year 2020 the mean annual rate of reduction in mortality for males age 65 and over will average about 0.58% for Canada, 0.76% for Mexico, and 0.67% for the U.S. The results for the female age 65 and over population are 0.64%, 0.83%, and 0.70%, respectively. The age 65 and over population is expected to see larger percentage reductions in mortality than the 0–14 and 15–64 populations. The reductions in male and female mortality will be ultimately the same, and the mortality levels in the three countries will ultimately converge, although differences may persist for decades.     

The Impact of the Inpatient Prospective Payment System and Diagnosis-Related Groups

Abstract

The outpatient prospective payment system for the Medicare program became effective Aug. 1, 2000, as mandated by the Balanced Budget Act of 1997. This outpatient program complements Medicare’s inpatient prospective payment system, which was introduced in 1983. A survey of the literature over the past 20 years is undertaken to review the effects of the inpatient prospective payment system and diagnosis-related groups (DRGs) on inpatient hospital utilization, expenditures, and outcomes. The level of the DRG payment has been questioned, as well as the process of adjusting the payment levels from one year to the next. In addition, past research has speculated that the DRG classification may not be sensitive to severity and is subject to coding ambiguities. These conclusions can be used as input to future research on the new outpatient program, as well as updating research on the inpatient program.
