Who are the world's most successful companies?

It seems that everybody wants to know which companies are the most successful. To help throw light on the issue, and to do so more reliably than the plethora of league tables and charts produced by most business magazines, the London Business School have teamed up with The Economist to compile an assessment of the top performers of the 1980's.     

Price rigidities and institutional variations in markets with posted prices

Summary Standard laboratory posted-offer markets respond slowly and incompletely to demand shocks. In these one-sided markets, where sellers control the setting of prices, very little information is transmitted via the process of exchange. For this reason, traders have trouble distinguishing randomness in their own experience from changes in market fundamentals. This paper reports the results of twelve laboratory markets conducted to assess whether some common variants to standard posted-offer rules can correct the adjustment deficiences. Although discounting, multiple postings and excess demand information all improve performance, we find that response remains poor, and efficiencies low.Support for this research was provided by the National Science Foundation (SBR 9319842 and SBR 9320044), and the University of Virginia Bankard Fund.

Managers' perceptions of ethical codes: dialectics and dynamics

Codes of ethics and conduct have become common in UK organisations. This paper explores how such codes are understood and responded to by those whom the codes seek to influence. The study is an interpretative one, based on interview material, in which a dialectical pattern is seen in employees' reactions to codes. Initial contradictions are found in codes of ethics (which claim to give employees space in which to exercise their integrity, but simultaneously are seen as impugning employees' moral status) and in codes of conduct (which require a loyal adherence to rules that interferes with wider loyalties). These tensions create perceptions of a two-tier system in organisations in which core employees are subject to codes of ethics that are loosely applied, but non-core staff are subject to codes of conduct that are strictly applied. However, even core staff are aware of a dialectical contradiction in their position. They believe that loyalty to the organisation is the price they pay for being allowed freedom of integrity by their organisations, but that the price they have to pay for showing integrity may be breaking faith with their organisations. This chiasmus of integrity and loyalty represents a difficulty for the project of improving standards of corporate citizenship. The use of this trope and other rhetorical figures to exemplify processes of understanding and interpretation in organisations is discussed.     

Food shopping and town centre vitality: exploring the link

Retail decentralization is associated with town centre decline and a concern for revitalization. Using the case of Llanelli, South Wales, the effects of a new food superstore on shopping behaviours and opinions are explored. Surveys in 1997, 1999 and 2001 reveal a dramatic change in patterns of food shopping, but no real change for purchases of clothing or DIY goods. Disadvantaged consumers, the carless and the elderly, were already heavily reliant on town centre shops before the opening of the new superstore and changes in their shopping patterns were no different from other shoppers. The 'social' vitality of the town centre increased, as did shoppers' satisfaction with town centre shopping, but major spin-off shopping or 'economic' vitality has not yet occurred.     

A comparison of alternative methods of updating input-output coefficients

In recent years there has been a growing number of input-output models of economies ranging in scale from the rural to the national. While offering invaluable insights into the interaction of sectors within an economy, the input-output model suffers from the fact that its coefficient values are altered over time due particularly to technological change. Two of the prominent techniques designed to update these technical coefficients, the RAS and linear programming methods, are compared herein with regard to changes in U.S. national coefficients between 1963 and 1967. Suggestions for improvements to the latter method are outlined.     

Brexit: How Will UK Agriculture Fare?

There is little doubt that Brexit would have significant implications for UK agriculture, a sector with strong trade links to the EU and strong reliance on CAP income support. This article reports preliminary results from employing a Computable General Equilibrium Model, a Partial Equilibrium Model and Farm Level Models to explore selected trade and domestic policy scenarios post‐Brexit. These allow for the estimation of changes in producer prices, production and farm incomes against a baseline scenario of continued EU membership. Under a Free Trade Agreement with the EU, agricultural impacts are relatively modest. By contrast, unilateral removal of import tariffs has significant negative impacts on prices, production and incomes. Adoption of the EU's WTO tariff schedule for all imports favours net importers (e.g. dairy) and harms net exporters (e.g. sheep). Given the strong dependence of most UK farms on direct payments, their removal worsens negative impacts of new trade arrangements and offsets positive impacts. Impacts vary across different types and sizes of farm, but also regionally. However, the period of adjustment to new trade and domestic policy conditions may prove very challenging for a large number of farm businesses.     

Firm-specific cost savings and market power

Summary. We report a policy experiment that illustrates a potential problem of using historical pass-through rates as a means of predicting the competitive consequences of projected firm-specific cost savings in antitrust contexts, particularly in merger analysis. The effects of cost savings on welfare can vary vastly, depending on how the savings affect the industry supply schedule. In a capacity-constrained price-setting oligopoly, we observe that cost savings can overwhelm behaviorally salient market power incentives when the savings affect marginal (high cost) units. However, cost savings of the same magnitude on an infra-marginal unit leave market power unchanged.     

Good timing: The economics of optimal stopping

This paper presents an economic interpretation of the optimal “stopping” of perpetual project opportunities under both certainty and uncertainty. Prior to stopping, the expected rate of return from delay exceeds the rate of interest. The expected rate of return from delay is the sum of the expected rate of change in project value and the expected rate of change in the option premium associated with waiting. At stopping the expected rate of return from delay has fallen to the rate of interest. Viewing stopping in this way unifies the theoretical and practical insights of the theory of stopping under certainty and uncertainty.     

Regulatory Impact Assessment in Developing and Transition Economies: A Survey of Current Practice

Regulatory impact assessment (RIA) involves a systematic appraisal of the costs and benefits associated with a proposed new regulation and evaluation of the performance of existing regulations. So far, most academic research has been concerned with the adoption of RIA in OECD countries. This article assesses the contribution that RIA can make to 'better regulation' in developing and transition economies. The results reported in this article suggest that a growing number of low and middle-income countries are beginning to apply some form of regulatory assessment, but that the methods adopted are partial in their application and are not systematically applied across government. The authors discuss the implications of their findings for capacity building and future research.
