The Usage of Electronic Data Interchange in the Hotel Industry

This study investigates the major factors that can influence electronic data interchange (EDI) within the hotel industry. Results illustrate that some profile, channel, and task variables can influence EDI usage in the areas of purchasing, financing, and strategy. By identifying and testing relevant intraorganizational variables, this study offers insights to academics and practitioners regarding the usage of EDI within the hotel industry. Indications are EDI could become an important tool for hotels to use in conducting business in both an interorganizational and intraorganizational manner.     

Applicability of global value chains analysis to tourism: issues of governance and upgrading

Tourism firms are increasingly integrated in value chains that often operate across many different countries. As a result, the concepts and the methodology of the global value chains begin to be applied to the tourism industry. This paper aims to explore the applicability of this methodological approach for a specific service industry, such as tourism. It pays particular attention to the impact of different patterns of governance within global tourism value chains on the possible forms of upgrading. First, a set of regional case studies carried out on this subject leads us to identify the main patterns of governance in the Andalusian tourism industry. Secondly, an empirical analysis allows us to consider in which way upgrading can vary according to the governance patterns.     

Monetary policy shocks and productivity measures in the G-7 countries

An implication of two-country international real business cycle models is that total factor productivity should be an exogenous stochastic process. Economic theories which feature labor hoarding, variable capacity utilization, and increasing returns predict that measured productivity shifts are not exogenous; instead, expansionary aggregate demand shocks should lead to an increase in measured productivity. For each of the G-7 countries, this paper measures quarterly aggregate total factor productivity for the domestic country and its rest-of-world (G-6) counterpart. In each case the domestic productivity measures are not strictly exogenous: expansionary U.S. monetary policy shocks, as well as other G-6 monetary policy shocks, lead to productivity expansions. The evidence indicates that international business cycle models are misspecified unless they feature endogenous productivity mechanisms.Received: June 2001, Accepted: December 2001, JEL Classification: E5, F4Correspondence to: Charles L.

The value of money in a dynamic equilibrium model

Summary. This paper studies the pricing of money in an infinite-horizon economy with heterogeneous agents, incomplete financial markets and arbitrary borrowing restrictions. Purchases of the consumption good are subject to a cash-in-advance constraint. Under general conditions I show that the price of money is equal to its fundamental value, where this value is defined over all state-price processes that are compatible with the existence of no-arbitrage opportunities. This equality implies that the cash-in-advance constraint is binding infinitely often for all agents in the economy. The analysis highlights certain differences in the determination of the price of money with respect to models with money in the utility function that bear on the optimal implementation of economic policies.Received: 23 October 2003, Revised: 26 August 2004 JEL Classification Numbers: D52, E44, G12.M.S.

Higher order properties of the wild bootstrap under misspecification

We examine the higher order properties of the wild bootstrap (Wu, 1986) in a linear regression model with stochastic regressors. We find that the ability of the wild bootstrap to provide a higher order refinement is contingent upon whether the errors are mean independent of the regressors or merely uncorrelated with them. In the latter case, the wild bootstrap may fail to match some of the terms in an Edgeworth expansion of the full sample test statistic. Nonetheless, we show that the wild bootstrap still has a lower maximal asymptotic risk as an estimator of the true distribution than a normal approximation, in shrinking neighborhoods of properly specified models. To assess the practical implications of this result we conduct a Monte Carlo study contrasting the performance of the wild bootstrap with a normal approximation and the traditional nonparametric bootstrap.     

Supply chain risk: empirical research in the automotive industry

Supply chain risk management (SCRM) has become a popular topic over the past decade. It is not a surprise that the automotive industry has been a motivating arena for research within this field; however, the few existing empirical studies reveal that SCRM practices within this industry are still in their infancy. Because the identification of risks can be viewed as the trigger for SCRM, attempts to develop a risk profile for this industry that could serve as a guide to start the SCRM process are needed. This research identifies the main risks along the automotive supply chain by investigating their manifestation in three supply chains in Brazil and offers an initial risk profile for the Brazilian automotive industry. Although the importance of SCRM has been recognised by all analysed companies, the research findings underline the lack of preparedness regarding either identifying risk or considering risk-mitigation strategies and risk assessment. In this context, this study identifies the main risk in which a supply chain can be exposed, through the analysis of real-life manifested risks along different supply chains, as a way to help the supply chain start a SCRM process.     

Assessing French inflation persistence with impulse saturation break tests and automatic general-to-specific modelling

This article has three different motivations. Firstly, we wish to contribute to the debate on whether French inflation has been persistent since the mid-eighties. Empirical evidence in this domain has been mixed. We use the standard method of testing for breaks in the mean of the inflation series to conclude whether possible unit root findings are the result of neglected breaks. Then, we build standard autoregressive representations of inflation, using an automatic general-to-specific approach. We conclude against inflation persistence in the sample period, and the point estimates of persistence we obtain are several percentage points below those achieved with other break tests and model selection methods. Moreover, our final model is congruent. Secondly, we provide the first empirical application of the new impulse saturation break test. The resulting estimates of the break dates are in line with other literature findings and have a sound economic meaning, confirming the good performance the test had revealed in theoretical and simulation studies. Finally, we also illustrate the shortcomings of the Bai–Perron test when applied to a small sample with high serial correlation. Indeed, we show the Bai–Perron break dates’ estimates would not allow us to build a congruent autoregressive representation of inflation.     

Back to the futures: An assessment of market performance on the early Winnipeg Grain Exchange

In this paper, I offer a quantitatively rich, historical perspective with which to consider Western Canada's recent return to private grain marketing. I assess how futures markets on the Winnipeg Grain Exchange (WGE) performed before the Canadian Wheat Board, and I consider the extent to which this performance contributed to the Canadian government's decision to create the Board. I conclude, despite significant agrarian dissatisfaction with private grain marketing on the WGE, the Canadian government ultimately proscribed futures trading because it was incompatible with the CWB model, which the Canadian government needed in order to stabilize farm incomes, particularly in the aftermath of the Great Depression.     

Mr Keynes,the Classics and the new Keynesians: A suggested formalisation

Abstract

The paper suggests a new Keynesian model of the General Theory. A reduced form entails a diagram with three curves relating employment and the real wage, which represent the two fundamental classical postulates and the principle of effective demand. This diagram illustrates better than IS–LM the generality of Keynes's theory, clarifying the distinction between voluntary and involuntary unemployment. Other significant features are the role of the distribution of expected interest rates among heterogeneous agents, whether dispersed or concentrated, in shaping the LM curve, as well as the role of wage competitiveness constraints as a foundation of Keynes's relative wage hypothesis.
