Road infrastructure and economic development in the periphery: the case of A55 improvements in North Wales

This paper examines the impact of a major road improvement programme on the economic development of North Wales. The paper identifies the economic impacts of the road on a selection of firms and organisations in North Wales, and provides a modelling framework to examine the static and dynamic effects of road improvements. Road improvements across North Wales are found to be a necessary, but not sufficient, condition for economic development in this peripheral area.     

Estimation of Agricultural Production Functfons on a World-Wide Basis

Agricultural production is becoming increasingly capital and research intensive. Hayami and Ruttan, along with others, have developed and applied the metaproduction functional approach to the examination of this phenomenon on a worldwide basis. Limitations to the approach derive from a restrictive functional form chosen for estimation, and from a restrictive specification of agricultural capital and land. This study addresses those difficulties by use of the flexible translog functional form for estimation and by specifying an overall agricultural capital index and a land measure incorporating differences in the quality of land (agricultural natural resource) endowments. Estimation results indicate that agricultural comparative advantage in production is likely shifting to developed countries relative to LDC's due to capital constraints in the latter. Also agricultural potential (i.e., land endowments) do not serve to differentiate nations on the basis of agricultural production. Investment in agriculture, including land improvement, is key to the determination of comparative advantage. La production agricole fait appelle de plus en plus a beaucoup de re-cherches et de capitaux. Hayami et Ruttan, avec d'autres, ont developpe et appliqué l'approche fonctionnelle métaproduction pour examiner ce phénomena à l‘échelle du monde. Les limitations de cette approache provienneent de la forme fonctionnelle restrictive choisie pour l'estimation, et de la spécification restrictive de capitaux et terres agricoles. Cette étude traite ces difficultés en utilisant la formule “translog’ fonctionnelle adaptable pour l'estimation et en spécificant un indice du capital agricole global et une mesure de terre qui incorpore les différences du qualité des terres agricoles (ressources agricoles naturelles). Tous les résultats estimatifs indiquent que l'avantage comparatif agricole de production s'incline vers les pays développés parraport aux PMD dû aux constraintes de capitaux dans ces derniers. Aussi la capacité agricole (c'est à dire la richesse des sols) ne sert pas à différencier les nations sur le plan de production agricole. L'investissement dans l'agriculte, notamment l'amélioration de terre, est la cief pour déterminer l'avantage comparatif.     

Uniform Commercial Policy, Illegal Trade, and the Real Exchange Rate: A Theoretical Analysis

Countries on fixed exchange rates sometimes use uniform tariffcum subsidy (UTCS) schemes as a way of achieving a real depreciationwithout disturbing the nominal exchange rate. A potential drawbackof this policy in relation to an across-the-board devaluationis that a UTCS scheme provides incentives for illegal trade.Using an optimizing model with currency convertibility and illegaltrade. I find that welfare is lower under a UTCS scheme thanunder a corresponding across-the-board devaluation and thatin some cases the real exchange rate actually appreciates inresponse to an increase in the UTCS rate.     

Combating Corruption in Indonesia? The Ombudsman and the Assets Auditing Commission

Early optimism that post-Soeharto governments would lead a systematic campaign against corruption has largely been disappointed. The creation of the ombudsman and the Assets Auditing Commission (KPKPN) were hopeful signs, but both initiatives are symptomatic of the weaknesses besetting Indonesia's anti-corruption efforts. Despite their best endeavours, both organisations have weak powers, are under-resourced, receive only token political support and exist in isolation from other investigative and enforcement agencies. International research suggests that official efforts to eliminate corruption are effective only as part of a coordinated campaign to reform administration, policy making, legislative institutions and the judiciary. Threatened exposure or punishment of corrupt officials is not enough: all the institutional incentives and disincentives for abuse of public office for private gain must be confronted. In Indonesia the problem is that most of those empowered to take such initiatives have no incentive to do so because they profit from the status quo.     

Does an Industry Effect Exist for Initial Public Offerings?

We examine the impact of initial public offerings (IPOs) on rival firms and find that the valuation effects are insignificant. This insignificant reaction can be explained by offsetting information and competitive effects. Significant positive information effects are associated with IPOs in regulated industries and the first IPO in an industry following a period of dormancy. Significant negative competitive effects are associated with larger IPOs in competitive industries, those in relatively risky industries, those in high‐performing industries, and those in the technology sector. IPO firms that use the proceeds for debt repayment appear to represent a more significant competitive threat to rival firms relative to IPO firms that use their proceeds for other purposes.     

Call centres and beyond: a thematic evaluation

This introduction aims to place the articles in this special edition in the context of the wider literature on call centres. The discussion is arranged around four themes: the characteristics and organisational features of call centre work, the choices and strategies that are available to manage the work, the effects of this type of work on employees and, finally, the responses and reactions of call centre staff to their work experiences. The articles selected, which are drawn from a conference sponsored by this journal, are then summarised.     

Permanent magnets: a technological analysis

Abstract
Technology analysis is a new technomanagerial discipline that provides common frameworks for analysing individual technologies and their relationships to each other. It is used here to probe the development of a particular technology, namely that of permanent magnets.
The paper traces the development of permanent magnets over the past decade and explores possible future improvements in performance parameters. The strength of magnets (i.e. energy product as expressed in kilo Joules per cubic metre) has increased from approximately 40 in the 1930s to approximately 400 at present.
Future developments will be constrained by a barrier which seems to exist at approximately 525 kilo Joules per cubic metre. However this is viewed as a barrier that can be transcended and not as an immutable limit. It therefore signifies a possible breakthrough zone.
S-curve theory leads analysts to speculate about a possible breakthrough during the five year period leading up to 1995. At that date magnetic strengths of 600+ kilo Joules per cubic metre could be aimed for.
Increased magnetic strength will improve the performance parameters of all technologies utilising magnets, unleash new magnetic based technologies and threaten many traditional areas in the fields of matter processing, transporting and storing, energy processing, and information processing and storing.
These effects will cascade through the entire technological landscape creating new markets and destroying others. The article gives an overview of these impacts on the technological landscape.

Who's in charge of the central city? The conflict between efficiency and equity in the design of a metropolitan area

A circular metropolitan area consists of a central city surrounded by a suburb. Households sort over the two jurisdictions based on public service levels and their costs of commuting to the metropolitan center. Using numerical simulations, we show that (1) there typically exist two equilibria: one in which the poor form the voting majority in the central city and the other in which the rich form the majority in the central city; (2) there is an efficiency vs. equity trade-off as to which equilibrium is preferred; and (3) if the central city contains only poor households, equity favors expanding the central city to include rich households. The third result arises not because of a fiscal subsidy from rich to poor households induced by a property tax but rather because of a change in house price capitalization.
