The endogenous national minimum wage institution

This paper offers reasoning for the endogenous sustainability of the National Minimum Wage Institution (NMWI). In an economy with asymmetries in productivity among unionized firms, high-tech firms may often opt for minimum wage agreements covering all unionized workers, in order to raise the relative costs of their rival low-tech firms. Their workers’ unions as well as the unions of workers in low-tech firms share this interest, provided that the degree of product substitutability is not too low and the wage agreement is not too high. Hence, since economy-wide minimum wage agreements prove to be compatible with the interest of all unions and high-tech firms, the NMWI can be sustained in equilibrium under politically convenient circumstances.     

On the Relevance and Comparability of Segmental Data

The recent adoption in the U.S.A. and Canada of the management approach to identify reportable segments places relevance of the disclosed segmental data as the overriding concern over comparability. This study investigates whether relevance and comparability are mutually exclusive or can be simultaneously achieved in segmental disclosure. It is explicitly recognized that both properties are a joint function of segment performance and segment identification, the performance–identification conundrum. By using a data set drawn from the U.K., a jurisdiction that explicitly allows directors' discretion when identifying reportable segments, and a series of tests which remove performance differences, the potential impact of segment identification on the relevance/comparability issue is highlighted. The results of the tests reveal that for a significant portion of the sample the levels of both relevance and comparability are simultaneously low due to the segment identification choices made. These choices appear to match the possible outcomes of following the management approach to identification.By implication, the adoption of the management approach may lead to reduced comparability and relevance in some cases.     

The dynamics of household beef consumption in Cameroon

Recent changes in economic conditions have introduced notable changes in household beef consumption patterns in Cameroon. While consumers are concerned about the short- and long-run effects of these factors on beef consumption habits, policy makers are more worried about the appropriate period necessary for households to make complete adjustments in consumption since this information is vital for planning production. Static and dynamic demand frameworks involving the Nerlovian partial adjustment (PA) model are used to capture the dynamic nature of beef consumption parameters. Maximum likelihood estimates of the PA model reveal that the conditioning variables explain 79% of the variation in beef consumption. Income, previous consumption, own-price and prices of fish and pork are jointly important in explaining beef consumption habits. Beef is a normal good with pork and fish as substitutes and chicken as a complement. Long-run price and income elasticities are greater than but not significantly different from their short-run values, suggesting that adjustment in consumption is fast with about 80% of the difference between actual and ‘desired’ consumption being completed in about 2 years. Projections show that demand for beef will reach 109620 t by the year 2000. giving an incremental total and per capita demand of 31 730 tons and 1.84 kg, respectively.     

Inflation volatility and stock prices: Evidence from ARCH effects

This paper examines the impact of inflation uncertainty on stock prices in developed as well as in emerging capital markets over the period 1980:1–93:12 via an Autoregressive Conditional Heteroskedasticity (ARCH) model for inflation. The results seem to support the presence of a negative association between inflation uncertainty and stock prices.The authors would like to thank, without implicating, Gikas Hardouvelis, Costas Karfakis, and especially the discussant of the conference session held in Williasmsburg, Robert C. Winder, for helpful comments and suggestions.     

Segmental Disclosure Practice: Thirteen Years On

In an age of financial disclosure directed by professional standards, the changes in practice voluntarily undertaken by companies are sometimes difficult to detect. By focusing on a period prior to the introduction of SSAP 25, the segmental disclosure issue offers an opportunity to consider whether practice has voluntarily changed. An examination of the extent and quality of segmental disclosure, for a specific group of companies over an extended period, offers an indication of the need for a standard or further regulation. If it can be demonstrated that disclosure practice has improved under a primarily self-regulatory framework, the need for a standard like SSAP 25 may be questioned. The segmental disclosure practices of the same group of seventy companies are compared for the reporting years 1975–6 and 1988–9. Whilst an underlying improvement in respect to business activity disclosure is revealed, the same cannot be claimed for geographic segmental disclosure. Not only has the number of companies reporting profit by geographic segment declined but also the consistency with other aspects of the annual report has reduced.     

Japanese Foreign Direct Investment in the UK Electronic Industry: The Eclectic Approach

This article analyses the combined effects of Japanese firms' ownership and location advantages on the size of foreign direct investment (FDI). The size of FDI is measured by two proxies, the firm's employment level and its total assets. Econometric models are estimated. The estimated regression models show that the parent company's firm-specific resources and the external economies in the located region determine the flow of FDI at the time of entry of Japanese electronic firms in the UK. This result shows that empirical analysis on FDI flows should combine both the ownership and location advantages, as suggested by Dunning's eclectic paradigm.     

Intellectual capital and innovativeness in software development firms: the moderating role of firm size

Abstract

We examine the effect of intellectual capital on firms’ innovativeness and the moderating role of firm size in software development firms in Kenya. Using moderated regression analysis, we found support for the proposition that human and social capital enhance firms’ innovativeness. We did not, however, find any significant effect of organizational capital on firms’ innovativeness. The results from the moderated regression suggest that the smaller the firm, the stronger the influence of intellectual capital on firms’ innovativeness. The results therefore indicate that human and social capital are critical in the innovation process and so firms that neglect these capitals are unlikely to realize the potential to innovate particularly in software development firms.
