Einige wichtige Indikatoren deuten darauf hin, dass der Innovationsstandort Deutschland im Bereich der forschungs- und wissensintensiven
Branchen seine derzeitige technologische Wettbewerbsposition im Vergleich zu wichtigen Konkurrenzl?ndern nicht dauerhaft halten
kann. Welche Schw?chen sind entlang der gesamten Wertsch?pfungskette erkennbar? Welche Ma?nahmen zum Gegensteuern sollten
ergriffen werden?

The United Kingdom has recently enacted smoking bans in public places such as restaurants and pubs. Public health advocates argue that bans are necessary because non‐smokers need protection from second‐hand smoke. Advocates also claim that bans do not exert harm on owners because of a vast empirical literature showing that restaurants and bars in the United States never suffer harm following bans. This paper examines whether these claims are true by developing a model within the Coasian framework whereby owners of businesses have incentives to deal with smoking disputes between smokers and non‐smokers. Our model demonstrates that it is incorrect to argue that smoking bans are necessary because the private market has no method of attempting to solve smoking problems. It also predicts that bans exert different effects on different businesses: some will be unaffected while others will experience losses or gains. Our literature review reveals that predictions of differential effects are consistent with the empirical evidence. 相似文献

Measuring Investment Distortions when Risk-Averse Managers Decide Whether to Undertake Risky Projects 总被引:2,自引:0,他引:2
We create a dynamic model in which a self-interested, risk-averse manager makes corporate investment decisions at a levered firm with characteristics typical of public US firms. We examine the magnitude of distortions in those decisions when a new project changes firm risk and find expected changes in the values of future tax shields and bankruptcy costs to be important factors. We evaluate the extent to which these distortions vary with firm leverage, debt duration, project size, managerial risk aversion, managerial non-firm wealth, and the structure of management compensation packages 相似文献

Using microdata from the 1998 and 1993 Nicaraguan Living Standards Measurement Survey, this paper analyzes the relative size and attractiveness of formal and informal sector employment. Switching regression models of the formal/informal sector employment choice indicate that education across years and gender are the primary determinants of formal sector participation. Furthermore, the formal sector is characterized by positive selection. The results for the informal sector are less definitive, but are also suggestive of positive selection. These findings imply that the informal and formal sectors in Nicaragua contribute positively to the overall economy by attracting those individuals best suited for (in)formal sector employment. 相似文献

We study the comparative statics implications of mean-variance preferences for optimal portfolios. Specifically, we show that all risk-averse mean-variance investors raise their investment in a risky asset in response to a change in that asset's return distribution if and only if the change lowers both the mean and standard deviation of the return by the same percentage. Besides being of interest in its own right, our results allow us to compare some comparative statics implications and the expected utility and mean-variance models systematically. 相似文献

Using British national survey data, this article assesses the impact of unions on management practices to reduce labour costs, implement high‐performance work systems, and make employee welfare provisions. Relative to non‐union workplaces, those with unions are found to have practices which are consistent with ‘mutual gains’ outcomes. 相似文献

A new railway is being planned across London. Incremental fares revenue will only pay about a quarter of the £10 billion1 expected cost, so the Greater London Assembly (GLA) is considering 'alternative funding mechanisms'. These include new taxes on businesses that are presumed to benefit from the scheme. Taxes would deter the very investment Crossrail is supposed to support. The GLA would do better to change the scheme to reduce the need for subsidy and strengthen the business case. 相似文献
