An additively separable representation in the Savage framework

This paper proposes necessary and sufficient conditions for an additively separable representation of preferences in the Savage framework (where the objects of choice are acts: measurable functions from an infinite set of states to a potentially finite set of consequences). A preference relation over acts is represented by the integral over the subset of the product of the state space and the consequence space which corresponds to the act, where this integral is calculated with respect to an evaluation measure on this space. The result requires neither Savage's P3 (monotonicity) nor his P4 (weak comparative probability). Nevertheless, the representation it provides is as useful as Savage's for many economic applications.     

Agricultural Export-Diversification and Economic Growth in Caribbean Countries: Cointegration and Error-Correction Models

This article uses cointegration and error-correction models to analyze the causal relationship between agricultural export diversification and economic growth in eight selected Caribbean countries using annual data from 1961 to 2000. The empirical results show that in the short run, agricultural export diversification Granger causes economic growth in Barbados and Belize. Noncausality exists for the other countries. In the long run, agricultural export diversification also Granger causes economic growth in the Dominican Republic. On the contrary, agricultural export diversification is the outcome of the economic growth process in Belize, Costa Rica, Haiti, and Jamaica, in the long run. Noncausality exists in Trinidad and Tobago. There is no evidence of bi-directional causality in any of the countries in either the short or long run.     

Estimating an origin–destination table for US imports of waterborne containerized freight

Containerized freight imports into the US are growing at an average of 10% per year. This traffic is concentrated at a small number of US seaports. It is therefore important to have an accurate understanding of the flow of containers from their origin country through these seaports to their final destination. This paper develops an optimization model to estimate route flows and a corresponding multi-modal origin–destination table for containers by synthesizing data on international trade and railcar movements with a gravity model for the demand of container traffic. This analysis provides insights into the balance of rail and truck inland transportation from each port.     

Supply Chain Management Competency and Firm Financial Success

Supply chain management (SCM) plays a major role in creating (or destroying) shareholder value by influencing the three major drivers of firm financial performance: revenue, operating costs, and working capital. Yet, the relationship between SCM competency and firm financial performance is not well‐established. Drawing on the resource‐based view of the firm, this study assesses this relationship using Delphi‐style opinion data from AMR Research’s Supply Chain Top 25 rankings to assess SCM competency and Altman’s (1968) Z‐score statistic as the measure of financial success. The study findings show that firms recognized by industry experts for SCM competency have significantly higher Z‐scores than their close competitors and industry averages.

HR in the small business enterprise: Assessing the impact of PEO utilization

Within small businesses, organizational leaders are themselves often responsible for the HR function, an area where they typically have limited training and experience. Not surprisingly, small business leaders have raised concerns about the quality of HR programs in their firms and the fact that HR consumes scarce managerial time. While professional employer organizations (PEOs) emerged in response to such concerns, much controversy exists as to whether and how small businesses benefit from PEO utilization. Using a survey of more than 740 small businesses, we examine the relationship between PEO utilization and two key small business outcomes: managerial time required by HR activities and satisfaction with HR outcomes. Our results indicate that firms not using a PEO reported significantly lower levels of satisfaction with HR outcomes than firms that used a PEO for a limited set of transactional services and firms that used a PEO for both transactional and strategic HR services. Among firms using a PEO, satisfaction with HR outcomes was significantly higher among firms that obtained a broader set of transactional and strategic HR services. Firms that used a PEO also reported that HR consumed significantly less managerial time relative to leaders in firms that made no use of a PEO. However, there was no significant difference in the time demanded by HR between firms that used a limited set of transactional services and those that used a broader range of transactional and strategic services. Implications for the role of PEOs and their use within small businesses are discussed. © 2005 Wiley Periodicals, Inc.     

Service Sector Protection: Considerations for Developing Countries

The inclusion of services in the Uruguay Round of multilateraltrade negotiations has focused attention on the protection ofdomestic service suppliers against competition from foreignsuppliers. Issues arising from these negotiations, however,may obscure another and more important issue: the case for unilateralliberalization. This article first surveys methods of protectionin the service sector, and then examines the likely cost ofprotection. Particular attention is given to developing countries.What evidence there is suggests that the costs of protectionmay be high. The article also discusses economic principlesthat could guide a review of policy toward international transactionsin the service sector. Quantitative restrictions or bans onforeign service suppliers—whether they wish to supplythrough trade or establishment—cannot easily be defendedin economic terms, and provide an obvious first target.     

The Industrial Relations Journal and the European Community

British entry into the European Community creates the conditions in which, for good or ill, the country's political, economic and social arrangements could be transformed. This observation applies at least as strongly to industrial relations as to other aspects of the national life. Indeed, it may even be argued that change in industrial relations in itself not only encompasses and reflects the broader patterns of socio-cultural and economic change occurring in society as a whole, but also, on occasion, is instrumental in initiating far-reaching changes outside the immediate concerns of industrial relations. Hence, the study of industrial relations could reasonably be seen as a study of society itself, in that both are concerned with the myriad of adjustments, large and small, which need to be made in the continuous task of reconciling, or providing a framework for reconciling, conflicting interests. Certainly, the study of industrial relations in a European Community context offers academics a practical and definable way of understanding the processes of integration in the organization of which Britain is now an important member. As far as managements and trade unions are concerned, short of some unusual catastrophe befalling multinational corporations, there must increasingly be a need to understand industrial relations systems and ideologies in countries other than our own for the severely practical business of negotiating viable agreements. In short, for the purposes of academic work and the requirements of the practitioner, industrial relations needs increasingly to be researched and discussed in a transnational as well as a national context, even though the latter must remain a large part of the reality for a long time to come.
