The recent findings by McCoskey and Selden (1997, Journal of Health Economics, forthcoming) that health expenditure and GDP are stationary are driven by the omission of time trends in their ADF regressions. Since both health expenditure and GDP are trending, this omission raise serious doubts on...

This paper has two purposes. The first purpose is methodological and aims to extend previous work on efficiency analysis by implementing a multiple-output stochastic ray frontier production function model. This model generalizes the single-output stochastic frontier model to multiple-input,...

In this paper we test for existence of cointegration between health expenditure and GDP using data from 19 OECD countries for the period 1960-1995. Country-by-country and panel results based on the Johansen multivariate likelihood-based inference and a new panel test for cointegration rank are...

This paper investigates the effects of different health systems on cost efficiency in inpatient health care among the OECD countries. The results indicate that public contract systems are less efficient and that public integrated health systems are more efficient than public reimbursement systems.

This paper proposes an approach to specify and estimate multiple input, multiple output production frontiers and technical efficiency using a stochastic ray frontier production model A possible model extension is to incorporate a technical efficiency effects model to allow estimation of the...

This paper presents a new dynamic ARCH-related conditionally heteroscedastic stochastic frontier model specification where firm and time-specific technical inefficiency is represented by an autoregressive stochastic process in the error components. Monte Carlo results reveal that a one-sided...

The purpose of this paper is to use the bootstrap resampling technique to calculate confidence intervals for efficiency measures and Malmquist productivity indices. The efficiency and productivity measures are obtained from non-parametric linear programming models using primal production data....

This paper shows that the bootstrap algorithm for average technical efficiency by Atkinson and Wilson (1995) should be applied with great care for the Data Envelopment Analysis (DEA) estimator if the production frontier is stochastic. A stochastic frontier implies that the DEA estimator is...

This paper discusses the definition, computation and interpretation of cost-effectiveness acceptability curves. A formal definition of the cost-effectiveness acceptability curve based on the net benefit approach is provided. The curve can be computed using parametric or non-parametric techniques...

This paper presents and applies different approaches to estimate returns to scale in multiple-input muliple-output technologies. Scale efficiency gives quantitative information of scale characteristics. A primal based approach to estimate the scale elasticity is proposed as an alternative to the...
