The best of all monopoly profits is a quiet life.

This paper proposes an interpretation and a test of Hicks' assertion concerning monopoly. We suggest that one source of monopoly survival is a comparative advantage in producing a quiet, long life. To test this hypothesis, we compare the life expectancy of executives in banking, an industry in which competition was constrained by regulations during the period examined, with the life expectancy of their counterparts in less regulated industrial firms. Bankers had a lower age adjusted mortality rate.

Utilization of health and mental health services. Three Epidemiologic Catchment Area sites.

Utilization of health and mental health services by non-institutionalized persons aged 18 years and older is examined based on interviews with probability samples of 3,000 to 3,500 persons in each of three sites of the National Institute of Mental Health Epidemiologic Catchment Area (ECA) program: New Haven, Conn, Baltimore, and St Louis. In all three ECAs, 6% to 7% of the adults made a visit during the prior six months for mental health reasons; proportions were considerably higher among persons with recent DSM-III disorders covered by the Diagnostic Interview Schedule (DIS) or severe cognitive impairment. Between 24% and 38% of all ambulatory visits by persons with DIS disorders were to mental health specialists. In seeking mental health services, men were more likely to turn to the specialty sector than to the generalist; women used both sectors about equally. The aged infrequently received care from mental health specialists. Visits for mental health reasons varied considerably depending on specific types of DIS disorder.

Out-of-plan use under two prepaid plans.

This analysis of out-of-plan use of physician and paramedical services under a Kaiser plan and under a prepaid option offered by a predominantly fee-for-service group practice (Clinic plan) deals primarily with services that members could have obtained from plan providers ("covered services"). The extent and pattern of out-of-plan use were found to be similar. While 16-20 per cent of plan members used some out-of-plan covered services and the mean number of such services was about one half visit per member per year, most out-of-plan user were occasional user, 10-12 per cent of user (or 2 per cent of plan members) accounting for 50 per cent of all out-of-plan covered services. The principal members characteristics associated with out-of-plan use were dissatisfaction, health status and having other insurance. The literature on out-of-plan use is also reviewed.

Use of physician services under two prepaid plans.

Use of physician services under two prepaid plans offered to Stanford University staff is analyzed and compared. One is a Kaiser plan; under the other (Clinic plan), physician and outpatient ancillary services are provided by a predominantly fee-for-service group practice and hospital services are covered by a Blue Cross policy. The two plans provide much the same benefits but, in addition to the difference in their organization, they differ in their financial provisions. While the Kaiser plan has only a token copayment for office and home visits, the Clinic plan has a 25 per cent coinsurance provision applying to all physician and outpatient ancillary services. Despite these differences, the mean number of physician visits per year is the same for the two groups after account is taken of differences in age composition, socioeconomic status, health status, attitudes toward seeking care, length of plan membership, family size and satisfaction with the plan. However, when adjustment is also made for differences in physician affiliation, the Kaiser rate becomes half a visit higher than the Clinic rate. This is because under both plans, members who have a specific plan physician as regular source of care use more services than those without one, and because only 42 per cent of Kaiser members compared with 87 per cent of Clinic members stated that they had a specific plan physician.

Factor affecting the choice between two prepaid plans.

This study examines the factors affecting the choice between two comprehensive prepaid plans of medical care available to the staff of Stanford University. One is a Kaiser plan, offered since 1969. Under the other (Clinic plan for short), medical services are provided by a predominantly fee-for-service group practice and hospital services are covered by a standard Blue Cross hospital policy; the Clinic plan has been available since the 1950s. The Kaiser plan has only a token copayment for office and home visit while the Clinic plan has a 25 per cent coinsurance provision applying to all physician and outpatient ancillary services. It was found that the two major factors affecting choice were income and distance to the provider. The preference for the Kaiser plan increased as income decreased. Similarly, as distance from the Clinic increased and distance from a Kaiser facility decreased, the preference for the Kaiser plan increased. However, proximity to the provider was a more important factor for the higher-income Clinic plan subscribers. The data also show that the longer availability of the Clinic plan had a long-term effect on enrollment. A substantial proportion of long time Stanford employees who might have been expected to prefer the Kaiser plan stayed with the Clinic plan.
