The challenge of optical fibres

Optical fibre technology can supply enormous bandwidth to meet the demands of the ever expanding telecommunications services. It has been said that they are the biggest competitors to satellites. This article outlines the history of optical fibres and how they work, and compares the benefits of both optical fibres and satellites for the communications market of the future. Geostationary satellites offer a global interconnectivity from both mobile and fixed points. Optical fibres offer heavy routing of both voice and data messages, freedom from interference, and cost advantages. The authors conclude that both will survive.     

Ethics in accounting: Values education without indoctrination

The integration of ethics into accounting curricula is a critical challenge facing accounting educators. The ethical subject matter to be covered and the role of the professor in ethical debates in the classroom are important unresolved issues. In this paper, we explore teaching basic values as an integral part of ethics education. Concern about indoctrination of students is addressed and the consistency of values education with the goals of ethics education is examined. A role for ethics researchers in identifying and clarifying the basic values that define our profession is recommended, and suggestions for implementing values education in accounting ethics are provided.H. Fenwick Huss is Associate Professor of Accounting at Georgia State University. His recent research focuses on ethical and regulatory issues in financial reporting. He has presented papers and served as a panel member in sessions on ethics at regional American Accounting Association conferences.Denise M. Patterson is a doctoral candidate at Georgia State University. Her research interests are in the areas of auditing and the impact of ethics on the role of the auditor. Denise has audit experience with an international accounting firm.     

Quantifying the impact of services liberalization in a developing country

We compare goods versus services liberalization in terms of welfare, outputs, and factor prices in Tunisia using a CGE model with multiple products, services and trading partners. Restraints on services trade involve both cross-border supply (tariff-equivalent price wedges) and on foreign ownership (monopoly-rent distortions and inefficiency costs). Goods-trade liberalization yields a modest gain in aggregate welfare. Reducing service barriers generate relatively large welfare gains and low adjustment costs. Services liberalization increases economic activity in all sectors and raise the real returns to both capital and labor. The results point to the potential importance of deregulating services provision for economic development.     

Observed Inflation Forecasts and the New Keynesian Phillips Curve*

This paper investigates the empirical success of the New Keynesian Phillips Curve (NKPC) in explaining US inflation when observed measures of inflation expectations are used in conjunction with the output gap. The paper contributes to the literature by addressing the important problem of serial correlation in the stylized NKPC and developing an extended model to account for this serial correlation. Contrary to recent results indicating no role for the output gap, we find it to be a statistically significant driving variable for inflation, with this finding robust to whether the inflation expectations series used relates to individual consumers, professional forecasters or the US Fed.     

Religious identity in the workplace: A systematic review,research agenda,and practical implications

We conducted a systematic review of relevant literature to address how religious and occupational identities relate to each other in the workplace. We identified 53 relevant publications for analysis and synthesis. Studies addressed value differences associated with religion and occupation, identity tensions, unmet expectations, and the connection of religious identity to well-being and work outcomes. Key variables in the connection between religious and occupational identities included personal preferences, the fit between religious identity and job-related concerns, and the organization's policies, practices, and expectations. We highlight the personal and organizational consequences of being able to express religious identity at work and the conditions that promote high congruence between religious identity and its expression in the workplace. From these findings, we develop a research agenda and offer recommendations for management practice that focus on support for expression of religious identity at work while maintaining a broader climate of inclusion.     

Four essays on economic evolution: an introduction

This essay is in two parts. The first considers the evolution of evolutionary economics from 1982 to 2012. While enormous advances are acknowledged, it is argued that the field is in danger of fragmentation and that there has been relatively little development in its over-arching theoretical framework since Nelson and Winter (1982). This sets the scene for a 2011 workshop and four of the papers presented at the event. In the second part, each paper is outlined in turn, both in terms of its specific contribution and any light it may shine on the problems raised in the first part.     

THE RELATIONSHIP BETWEEN TOURISM AND TRADE IN SOUTH AFRICA

This article explores the relationship between tourist arrivals and trade in South Africa. Two analyses were conducted – a panel data analysis, which included tourism and trade data of 40 countries with South Africa, and a time‐series analysis that involved South Africa's main tourism and trade partners. Cointegration tests, Granger causality and Block exogeneity tests were used to investigate the nature of the relationship. The results of the panel data analysis show that for South Africa as a whole, there is indeed a long‐term relationship between tourist arrivals and trade, and that bidirectional causality exists. The results for the country case studies are mixed, although the evidence is stronger for the hypothesis that tourism causes trade.     

Welfare Reform and the Labour Supply of Lone Parents in Australia: A Natural Experiment Approach

Large shifts in the labour supply of lone parents in Australia were observed between 1986 and 1990. Changes in the observed characteristics of lone parents explain only a small portion of these shifts. Propensity score matching and difference-in-differences are used to estimate the effects of the substantial policy shifts implemented in 1987. Control groups are constructed from the sample of married mothers. Results suggest that the policy reforms caused a substantial increase in the employment of lone parents while causing a reduction in the hours of work among the workers.     

Intellectual Property Rights in the Asian-Pacific Region: problems, patterns, and policy

This paper explores recent theory and evidence regarding increased protection of intellectual property rights (ZPRs) in Asia. Knowledge has significant public good aspects making optimal provision a problem of trading off universal access against adequate incentives for R&D. Given the ease of evasion of IPR relative to tariffs, attempts to push low and middleincome countries to higher levels of protection may be against their national interests. The Uruguay Round may encounter less than enthusiastic enforcement. Further efforts to refine IPR protection might usefully be focused on flexibility instead of harmonisation.
