An investigation of international hotel productivity considering quasifixed inputs and negative outputs

This paper explores the productivity of international hotels by considering the number of guest rooms and the area of the catering department as quasifixed inputs, because neither can be easily changed over a short period. We introduce a range-adjusted measure model to incorporate both quasifixed inputs and negative outputs and propose a nonradial Malmquist productivity index to estimate dynamic productivity. The results show that chain-operated hotels were unable to generate operational synergy to enhance their competitiveness, but their productivity outperformed that of independently operated hotels in cross-period aspect. Finally, we provide improvement suggestions for managers.     

Sources of airline productivity from carbon emissions: an analysis of operational performance under good and bad outputs

This study incorporates carbon dioxide emissions in productivity measurement in the airline industry and examines the determinants of productivity change. For this purpose a two-stage analysis under joint production of good and bad outputs is employed to compare the operational performance of airlines. In the first stage, productivity index are derived using the Luenberger productivity indicator. In the second stage, productivity change scores derived therefrom are regressed using the random-effects Generalized Least Squares to quantify determinants of productivity change. The paper finds low cost carriers and average number of hours flown per aircraft having a positive impact on productivity under joint production model while demand variable negatively impacts on productivity under market model.     

Total quality management and human resource systems: an international comparison

This paper takes advantage of a unique international data set to examine the determinants of the adoption and sustainability of total quality management techniques, focusing in particular on the role played by human resource professionals and practices. The data come from a 1991 survey conducted by Ernst and Young and the American Quality Foundation covering the use of TQM tools in the computer, auto, health care and banking industries in Japan, the United States, Canada and Germany.

The research distinguishes between two ways of implementing total quality management – one approach conceptualizes TQM as a relatively limited set of technical engineering changes while the second implements these technical changes as part of a larger transformation of the organization of work. We find support for the second approach in that the number of employees using quality tools and the number of quality tools in use is greater and lasts longer in firms that also have team-based human resource systems for frontline employees, with team structures, suggestion systems, meetings and group rewards. This central finding holds across all countries and industries studied.

We also find that achievement of these changes requires the commitment of organizational stakeholders to incorporate the interests of employees in strategic decision making. Though union presence alone does not predict the adoption or sustainability of these innovations, partnership between management and union does have a positive effect. The level of strategic influence of the human resource department also influences innovation, though in ways that differ across countries and industries.

The findings suggest the value of comparative studies and of research focused at exploring sub-national variation. The findings also suggest the value of a longitudinal study of the sustainability of innovation.     

Monetary policy announcements and stock reactions: An international comparison

This article investigates the impact of domestic monetary policy rate announcements on the stock markets of New Zealand, Australia, the United Kingdom and the euro area, using event-study methods to identify stock price reactions to the unanticipated/surprise component of announcements. As Australia and New Zealand did not reach the zero bound we investigate whether there is an impact from the global financial crisis on stock market reactions that can be distinguished from the asymmetric reactions to surprises that characterise the business cycle. We find that the euro area and the UK both show a financial crisis effect but behaviour in New Zealand and Australia does not change. We conduct robustness checks and explore confounding factors, especially the impact of ‘guidance’ from central banks that prepares markets for policy rate changes.     

Evaluation of ecological systems and the recycling of undesirable outputs: An efficiency study of regions in China

A balance between environmental regulation and economic prosperity has become a major issue of concern to attain a sustainable society in China. This study proposes the application of Data Envelopment Analysis (DEA) for measuring the efficiencies of the ecological systems in various regions of that country. The proposed approach differs from most of the previous ecological systems models in that we view it in a two stage setting; the first stage models the ecological system itself, and from an economic perspective, while the second stage (decontamination system) models water recycling as a feedback process, and the treatment of other undesirable outputs coming from the first stage. There, we separate polluting gases and water into two parts; one part is treated, while the other is discharged. The model considers two major desirable outputs from the first stage, namely Population and Gross Region Product by expenditure (GRP), as well as undesirable variables in the form of consumed water, and certain pollutants, namely nitrogen oxide, sulfur dioxide and soot. At the same time, these undesirable outputs from the first stage are inputs to the second decontamination stage. As well, recycled water is fed back into stage 1. Thus, intermediate variables such as consumed water and waste gas emission simultaneously play dual roles of both outputs and inputs in the ecological system.     

Causality in temporal systems: Characterization and a survey

A time series {Y_t} ‘causes’ another time series {Y_t}, in the sense defined by C.W.J. Granger, if present Y can be predicted better by using past values of X than by not doing so, other relevant information (including the past of Y) being used in either case. In this paper we (1) classify the possible causality relationships between two series X and Y, using an analogy to events in a sample space; (2) review existing work and present some new results on alternative characterizations of the more important causality events; and (3) compare several recent procedures for the empirical detection of causality.     

An international comparison of economic leading indicators of telecommunications traffic

The purpose of this paper is to draw international comparisons of the coherence of indexes of leading economic indicators with selected telecommunications traffic series. The traffic series under consideration are total Australian telephone outgoing and U.S. outgoing telephone to Australia with data consisting of monthly observations spanning the period 1970–1983. The response of the telecommunications traffic to these indexes is analysed using cross-spectral techniques. Additionally, a dynamic regression forecasting model for Australian traffic is estimated using the Australian index as an explanatory variable. In comparison to an ARIMA model for the telecommunications data this model reduces post-sample MSE by 19 percent.     

An international comparison of human resource management objectives and activities

The paper reports on mailed surveys of human resource professionals in Canada, South Africa and Zimbabwe who were asked for their views on the priorities they set in terms of human resource objectives and activities. Respondents were also asked to indicate the challenges facing the field and the resulting changes that may be required in each country. The results indicate considerable agreement between the three countries on the need for flexibility and cost effectiveness, but disagreement on priorities among some other activities. There are major differences between perceptions of immediate and long-term priorities to be set. There is a concern that short-term efficiency may be accorded a priority which prevents due consideration being given to future development and societal issues.     

An empirical analysis of international labour migration in the Philippines

This study empirically investigates the impact of economic, demographic, and political factors on the size of emigration from the Philippines. In 2007, overseas workers from the Philippines sent remittances in excess of US$14 billion annually to their families back home. Although these remittances are an important source of foreign exchange and play an important role in economic development, the determinants of emigration in the Philippines are not well established. A simple unrestricted error correction model of migration was specified and estimated using data spanning the period 1975–2005. Results indicate that the level of unemployment, adult literacy and population density are the key determinants of emigration in the Philippines. The result also indicates that government instability impacts negatively on emigration in the Philippines. The policy implications of the results are discussed.     

Designing vendor evaluation systems: An empirical analysis

Companies today are increasing efforts to develop their vendor evaluation system (VES) to qualify and select the best suppliers, monitor their performance and foster continuous improvement. VES lies at the intersection of three disciplines: purchasing management, supply chain management, and performance management. The extant literature especially focuses on vendor rating tools from a mathematical modeling standpoint, whereas firms are mostly concerned with guidelines necessary to design and implement an effective VES. The present study develops an encompassing research framework to investigate VES by means of thirteen case studies. In particular, the paper investigates VES design in terms of strategic alignment, process configuration and execution, as well as corresponding benefits and costs, exploring how the combination of the previous elements determines company satisfaction. Three groups of VESs are identified, leading to different levels of satisfaction.     

Generalised estimates of diffusion rates for the oxygen blown steel process: An international comparison

The purpose of this study is to build on the results recently obtained by Poznanski (1990). First, the estimation technique is generalised by removing both the symmetric restrictions and the effects of autocorrelated errors that are present in simple logistic functions. Secondly, attention is drawn to the existence and consequences of multicollinearity when non linear techniques are applied to a general exponential. Thirdly, an attempt is made to quantify the importance of market structure and time lags in adoption as determinants of diffusion speed. Finally, a comparison between these generalised results and Poznanski's is made.The study concludes that, by generalising the estimation technique, some significant changes take place. Changes occur in the ordering and magnitude of diffusion speeds, especially amongst the developing and centrally planned economies. Changes also occur in the nature of the diffusion process, and in the importance attributed to market structure and diffusion lags in determining the rate of diffusion. It is also shown that, for some countries, multicollinearity imposes constraints on the type of generality that can be obtained.     

Global governance in new public environmental management: An international and intertemporal comparison of voluntary standards' impacts

The aim of this paper is to analyse the indirect effects of environmental management system implementation and certification. Specifically, the paper comprehensively assesses the effects of International Organisation for Standardisation (ISO) 14001 and European Union Eco‐Management and Auditing Scheme (EMAS) certification as well as experience with implementing environmental management systems on (a) organisational activities outside the scope of environmental management systems, (b) pollution prevention, and (c) product stewardship. This is done by applying multivariate regression analysis to a large multicountry and multiperiod dataset. The analysis finds heterogeneous effects that are limited specifically as concerns pollution prevention and product stewardship and cannot establish clear links to national business systems. Given this and the differences between environmental management system standards, implications for global governance in the context of new public environmental management and the role of national governments in implementing sustainability, even beyond environmental protection, are discussed. Ultimately, the paper evidences on potential limitations of the major international environmental management system standards ISO 14001 and EMAS in supporting the diffusion of advanced practices such as pollution prevention and product stewardship that are necessary for sustainable development. In doing so, it highlights that government‐led public environmental management remains crucial for organising governance, especially in the context of voluntary standards that are applied internationally.

Typology of structural change in a regional economy: a temporal inverse analysis

Earlier studies have investigated the hollowing-out phenomenon of the Chicago economy, in which the manufacturing sectors in Chicago have decreased their intermediate dependency within the region while the service sectors have increased their dependency. In this paper, a series of annual input–output tables for the Chicago metropolitan economy during the period of 1980–1997 was again employed for a further investigation of the structural change using an alternative tool, the temporal Leontief inverse analysis, that can assist in exploring trends and uncovering tendencies in individual sectors or groups of sectors within the context of an economy-wide system of accounts. The results are compared with the earlier studies for examining the nature and details of the hollowing-out phenomenon.

Efficiency in Islamic and conventional banking: an international comparison

The paper investigates the efficiency of a sample of Islamic and conventional banks in 10 countries that operate Islamic banking for the period 1996–2002, using an output distance function approach. We obtain measures of efficiency after allowing for environmental influences such as country macroeconomic conditions, accessibility of banking services and bank type. While these factors are assumed to directly influence the shape of the technology, we assume that country dummies and bank size directly influence technical inefficiency. The parameter estimates highlight that during the sample period, Islamic banking appears to be associated with higher input usage. Furthermore, by allowing for bank size and international differences in the underlying inefficiency distributions, we are also able to demonstrate statistically significant differences in inefficiency related to these factors even after controlling for specific environmental characteristics and Islamic banking. Thus, for example, our results suggest that Sudan and Yemen have relatively higher inefficiency while Bahrain and Bangladesh have lower estimated inefficiency. Except for Sudan, where banks exhibits relatively strong returns to scale, most sample banks exhibit very slight returns to scale, although Islamic banks are found to have moderately higher returns to scale than conventional banks. While this suggests that Islamic banks may benefit from increased scale, we would emphasize that our results suggest that identifying and overcoming the factors that cause Islamic banks to have relatively low potential outputs for given input usage levels will be the key challenge for Islamic banking in the coming decades.     

Bayesian measurement of productivity and efficiency in the presence of undesirable outputs: crediting electric utilities for reducing air pollution

Many studies have measured productivity change and efficiency when an undesirable output is a by-product. We flexibly treat the bad as a technology shifter of an input distance function and model a system of nonlinear equations subject to endogeneity. Theory dictates that we impose monotonicity on all inputs, outputs, and the bad. Since a Bayesian full-information likelihood approach can easily be misspecified, we utilize the Kim (J. Econometrics 107 (2002) 175) limited-information likelihood (LIL) derived by minimizing the entropy distance subject to the moment conditions from the Generalized Method of Moments (GMM) estimator. This represents an extension of the Bayesian Method of Moments approach of Zellner and Chen (Macroeconom. Dyn. 5 (2001) 673), Zellner and Tobias (Int. Econom. Rev. 42 (2001) 121), and Zellner (in: Bayesian Analysis in Econometrics and Statistics: The Zellner View and Papers, Edward Elgar, Cheltenham, 1997; J. Econometrics 83 (1998) 185) which uses entropy maximization but does not incorporate a specific likelihood. Using Bayes’ Theorem we combine traditional priors with the LIL, which has a mode at the standard multiple-equation GMM estimator, yielding a limited-information posterior distribution. We generalize the approach of Kim (J. Econometrics 107 (2002) 175) by incorporating an unknown covariance matrix in a Gibbs sampling framework and applying the methodology to nonlinear equations. This allows us to estimate shadow prices, technical efficiency, and productivity change for a panel of electric utilities, yielding results that differ substantially from those obtained using standard GMM.     

An economic analysis of Japanese distribution systems

We investigate Japanese distribution systems by using a successive monopoly model in which the dealer can increase demand for the commodity. We compare the Tatene system (TS) with the open price system (OPS), and show that in cases where the dealer's power of sales promotion is small (large), the total profits obtained through TS become larger (smaller) than those of the OPS. This result justifies the actual change from TS to OPS from an economic point of view. Copyright © 2003 John Wiley & Sons, Ltd.     

An analysis of operations efficiency in large-scale distribution systems

This research applies Data Envelopment Analysis (DEA) methodology to evaluate the efficiency of units within a large-scale network of petroleum distribution facilities in the USA. Multiple inputs and outputs are incorporated into a broad set of DEA models, yielding a comprehensive approach to evaluating supply chain efficiency. This study empirically separates three recognized, important and yet different causes of performance shortfalls which have been generally difficult for managers to identify. They are: (1) managerial effectiveness; (2) scale of operations and potential for a given market area (and efficiency of resource allocation given the scale); and (3) understanding the resource heterogeneity via programmatic differences in efficiency. Overall, the efficiency differences identified raised insightful questions regarding top management’s selection of the appropriate form and type of inputs and outputs, as well as questions regarding the DEA model form selected.     

Accounting for growth in retail trade: an international productivity comparison

In this paper we argue that the standard approach for measuring output and productivity in the trade sector has become obsolete. The key problem is that changes in prices of goods purchased for resale are not accounted for. We outline a consistent accounting framework for measuring trade productivity and provide new estimates, taking into account purchase prices of goods sold in a double deflation procedure. We find strong productivity improvements in the UK and US compared to France, Germany and The Netherlands since the mid-1990s. This finding is robust for various productivity measurement models.
