Purpose – The major aim of this paper is to model, estimate and compare the technical efficiency and technology gap ratios of health care foodservice operations that operate in different Australian regions. Design/methodology/approach – This paper uses a metafrontier model to analyse the...

In this article, the authors have considered the use of data envelopment analysis (DEA) to calculate and analyze the level of technical, allocative, and cost efficiencies of Australian hospital foodservice operations. Based on the DEA outcomes, a Tobit regression model was then introduced to...

This article analyses the efficiency of health care foodservice operations and its determinants using a Data Envelopment Analysis (DEA) bootstrapping approach. The purpose of using the bootstrapping approach is two-fold: first, to obtain the bias corrected estimates and the confidence intervals...

Cost efficiency and cost data in the health care foodservice sector have many interesting features. Traditional productivity approaches and empirical studies are yet to address many of these features, as they are limited to partial ratios and restricted parametric techniques. In this paper, we...

The major aim of this paper is to model, estimate and compare the technical efficiency and technology gap ratios of health care foodservice operations that operate in different Australian regions. This paper uses a metafrontier model to analyse the difference in health care food efficiency...

This paper aims to reflect on the sources of the technical inefficiency of health care foodservice operations, using a sample of Australian and American hospitals. The paper applies the stochastic frontier model to reflect on the technical inefficiency and its sources. The advantage of the model...

This study examined the impact of the financial crisis on the environmental and technical efficiencies of the Japanese manufacturing industry. Overall, we found that while the crisis had a negative impact on technical efficiency it did not affect environmental efficiency- the only exception was...

This paper revisits the relationship between fiscal size and economic growth. Our work differs from the empirical growth literature because this relationship depends explicitly on the efficiency of the public sector. We use a sample of 64 countries, both developed and developing, in four...

We propose a new model for transaction data that accounts jointly for the time duration between transactions and for the discreteness of the intraday stock price changes. Duration is assumed to follow a stochastic conditional duration model, while price discreteness is captured by an...

We use a novel Bayesian inference procedure for the Lyapunov exponent in the dynamical system of returns and their unobserved volatility. In the dynamical system, computation of largest Lyapunov exponent by tradi- tional methods is impossible as the stochastic nature has to be taken explicitly...
