Management buy-outs,trade unions and employee ownership

Management buy-outs developed rapidly throughout the 1980s in the UK and continental Europe. The shift to managerial and employee ownership involved, has major implications for trade unions and industrial relations. This article examines these issues using survey and case study evidence from the UK.     

EXCHANGE RATE RISK AND EXPORT REVENUE IN TAIWAN

Abstract. The effect of exchange rate risk on export revenue in Taiwan between 1979 and 2001 is investigated in a bivariate GARCH-M model that simultaneously estimates time-varying risk. Depreciation is found to stimulate export revenue in domestic currency, but the quantitative impact is small and any associated increase in exchange risk has a negative impact. Implications for economic policy are discussed.     

Importance for DEA of zeros in data,multipliers, and solutions

Some prominent literature in the DEA field has displayed the following three problems involving zeros: (1) The structural role of zeros in data has not necessarily been recognized; in fact, without explanation, arbitrary, small positive numbers have been substituted for such zeros. (2) It is not well recognized that the artificial, non-Archimedean construct is not necessarily needed to exclude zero multipliers and to identify positive slacks. (3) Because of degeneracy, optimal solutions are not necessarily unique; this lack of uniqueness is especially important in interpretation of the multipliers and slacks.The editor for this paper was R. Robert Russell.     

Testing for negative expected market return premia

This paper tests the hypothesis that the expected return premium on the market portfolio is always non-negative. A violation of this lower bound restriction provides evidence against a broad class of risk-based equilibrium models in favor of bubble behavior. Our tests utilize information variables, identified in prior literature, that predict time variation in market return premia. We employ out-of-sample forecasts and bootstraps generated with parameters that are consistent with non-negativity but closest to the estimated parameters. We find statistically reliable evidence against non-negativity for the excess return on the value-weighted market index. The most negative out-of-sample prediction was −2.01% in September 1973.     

Entry and Exit in a Transition Economy: The Case of Poland

The purpose of this paper is to examine the industrialentry and exit in a transitioneconomy, over the interval of change from a predominatelystate-owned productivesystem. The data set employed offers a near-exhaustivecoverage of manufacturingfirms in Poland. The paper estimates entry and exit equationsacross 152 3-digitindustries, using an adaptation of an Orr–Shapiro/Khemani-typemodel to allow for thespecial circumstances of a transition economy. Theresults suggest that, despite theturbulence of the immediate post-transition period,the patterns of entry and exitbehaviour in Poland correspond closely to thoseobserved in more mature marketeconomies.
