The Competitiveness of UK Manufacturing: Performance and Prospects

The competitiveness of UK manufacturing and its future prospects are examined in terms of productivity, the performance of high technology industries and the relationship between science and technology. Die main findings are that concentrating on productivity performance can be misleading and attention should also be paid to the structural aspects of competitiveness, especially the relationship between the science base arid industrial technology. On this basis we conclude that if the UK is to realise fully the competitive potential of technological change, differences in these structural aspects of competitiveness need to be addressed.     

THE EMERGENCE OF COPYING TECHNOLOGIES: WHAT HAVE WE LEARNED?

The past few decades have seen dramatic advancements in the technology of copying and the diffusion of copying technology to the general public. This paper surveys some of the recent academic literature dealing with this issue. We focus on (i) the effect of varying the extent of property rights enforcement by the government, and (ii) possible responses by producers of originals to consumers' ability to produce copies. The traditional view is that as the government increases property rights enforcement, there is a decrease in the social welfare loss due to underproduction and an increase in the social welfare loss due to under-utilization. In the first half of the paper, we show how the analyses contained in a number of recent studies throw doubt on this traditional viewpoint. In particular, varying the extent of property rights enforcement has effects that the traditional analysis ignores. As a result, the social welfare losses mentioned above can move in ways not recognized previously. The conclusion is that, contrary to what is sometimes suggested, choosing an optimal level of property rights enforcement by the government should not be viewed as a simple trade-off between these two social welfare losses. In the second half of the paper, we discuss possible market responses to consumers' ability to produce copies. Among other responses, we consider the role of price discrimination and complementary products when copying is possible.     

THE EFFECTS OF VERTICAL MARKETS ON TRADE POLICY REFORM

Typically, analysis of trade liberalization ignores the impactthat intermediate stages in the production and distributionsystem may have on the pass-through of changes in tariffs tofinal goods' prices. Using a model of a multi-stage system,this paper shows that both the number of vertical stages andthe degree of imperfect competition at any specific stage canaffect the degree of tariff pass-through. Simulation of themodel with respect to recent changes in the European Union bananaregime suggests that ignoring vertical market structure is likelyto over-estimate the benefits to consumers of trade liberalization.     

Corporate Disclosure of Environmental Liability Information: Theory and Evidence*

Abstract. The decision to disclose information concerning a firm's environmental liabilities is modeled as a sequential game involving the firm, a capital market, and outside stakeholders who can impose proprietary (political) costs on the firm. A partial disclosure equilibrium is derived in which firms reveal information strategically, maximizing the share-value net of expected political costs. Inherent uncertainty regarding the existence and size of the liabilities creates a setting where outsiders are uncertain if management is informed about these liabilities, so firms can plausibly withhold “bad news”, that is, they do not disclose liabilities that exceed a threshold level. Three novel hypotheses are that a firm is more likely to disclose as (1) its pollution propensity increases, (2) outsiders' knowledge of its environmental liabilities increases, and (3) the risk of incurring proprietary costs decreases. Empirical support is found for the hypotheses, based on the accounting disclosures made by sample firms selected from the records of the Ontario Ministry of the Environment and Energy. Improved accounting and auditing standards for environmental disclosure would build on at least three implications of the study:

• 1 To the extent that inherent uncertainty leaves managers with discretion as to what to disclose, the partial disclosure equilibrium result suggests that not all firms will comply with disclosure standards.
• 2 Publishing broad environmental performance indicators for companies in nonaccounting outlets would increase public awareness of a manager's private information endowment, making voluntary accounting disclosures of the liabilities more likely.
• 3 If a significant decline in stakeholder tolerance of pollution occurs, the expected proprietary costs of disclosing increase, and companies become less likely to disclose.

     

Investment Horizon and Composition of Optimal Portofolio: International Evidence

Little attention has been paid in the literature to the impact of different investment horizons on the portfolio compositiondespite its importance to portfolio managers. One exception isthe study by Gunthorpe and Levy (1994) on the U.S. stock market.Our paper extends the same study to the stock markets of Japan,Hong Kong and Korea. Using 40 individual stocks in each market,our results support those of Gunthorpe and Levy (1994) in thatthe composition of an optimal portfolio depends heavily on theinvestment horizon. When the investment horizon lengthens, theproportion of defensive stocks becomes larger while that ofaggressive stocks becomes smaller.     

Tax Law Improvement in Australia and the UK: The Need for a Strategy for Simplification

In both Australia and the UK, programmes are under way to simplify tax legislation by rewriting it. This paper demonstrates that tax simplification is a complicated concept and concludes that sustainable improvement is unlikely to be achieved if reform is limited only to linguistic changes. Tax law is complicated because there are powerful pressures that tend to increase the complexity of modern tax systems and these should also be considered in any simplification programme. In addition, tax simplification may be promoted by the greater use of purposive legislation — that is, legislation drafted in terms of general principles rather than much more comprehensive legislation designed to deal with every likely possibility. The paper examines the progress of the Australian Tax Law Improvement Project and argues that what is needed is a strategy for tax simplification that is incorporated into the process of generating tax policy itself.
