This paper develops an economic model of the market for treatment of waiting list conditions, in which complainants choose between private treatment, NHS treatment and no hospital treatment. This choice depends on a number of clinical and non-clinical factors, which enter the demand functions for private and NHS treatment. ⋯ Given a pair of private sector and NHS supply functions, expressions are obtained for the price and expected wait at which demand and supply are simultaneously equated in both the private sector and the NHS. The paper concludes by exploring the responsiveness of the equilibrium to various demand side and supply side shocks.

This paper raises the question of the least-cost institutional mechanism to secure the value of certainty by reducing risk over the purchase of medical care. Two methods of reducing risk are evaluated: financing medical care with 'complete insurance', that is, ready access to medical care that is free at the point of purchase; and rationing by waiting time in a national health service that supplies a limited volume of medical care. The first system corresponds to the type of insurance held by most people in the United States, while the latter represents a stylized model of a national health service. ⋯ S. is substantial--larger on a per-family basis, and far larger for the nation, than the cost of under-utilization by those who lack insurance. The cost of rationing by waiting is estimated to be between $541 and $828 per family (in 1984 dollars). Thus, both systems involve costly mis-allocation of resources.

The evidence found in most studies suggests a strong positive relationship between health care expenditure and gross domestic product. However, this evidence weakens with respect to the actual value of the income elasticity. There are two possible sources of these discrepancies, the use of arbitrary deflators and specification errors. ⋯ The results for income elasticity are the same regardless of whether health care expenditure is converted using the GDP PPP or the 'universal' health price index. The importance of non-income variables is also confirmed, in particular the relative price of health care. We find that relative price has a strong rationing effect on the quantity of health demanded and has no effect on the expenditures.

Among the target-linked services introduced by the 1990 general practitioners' contract, childhood immunization in Scotland is the best suited for GPs to achieve the high target, given a centralized call and recall system and public confidence in the service. Yet over 25% of the practices in the area of the Greater Glasgow Health Board did not qualify for the high target payments in the last quarter of the 1991/92 financial year. Examining indicators of the socioeconomic characteristics of the patient population, practice profiles and the effect of financial incentives, we discuss the reasons for cross-practice variation in the uptake of this service and estimate the probability of practices which missed the high target achieving it in the future.
