We use expert clinical and public health opinion to estimate likely changes in the prevention and treatment of important disease conditions and how they will affect future life expectancy. Focus groups were held including clinical and public health faculty with expertise in the six leading causes of death in the United States. Mortality rates and life tables for 2040 were derived by sex and age. Life expectancy at age 20 and 65 was compared to figures published by the Social Security Administration and to estimates from the Lee-Carter method. There was agreement among all three approaches that life expectancy at age 20 will increase by approximately one year per decade for females and males between now and 2040. According to the clinical experts, 70% of the improvement in life expectancy will occur in cardiovascular disease and cancer, while in the last 30 years most of the improvement has occurred in cardiovascular disease. Expert opinion suggests that most of the increase in life expectancy will be attributable to the already achieved reduction in smoking rates, especially for women.  相似文献

We analyze the factors that drive exercise price policy for executive option plans (ESOPs) and their scope in a country where firms are not subject to the tax and accounting considerations that seem to have led to the dominance of at-the-money options in the US Our “unbounded” data for Finland provide us with an excellent opportunity to investigate whether contract design is consistent with compensation theory. Our findings are largely consistent with predictions from the optimal contracting literature. The size of the plan is negatively related to Tobin's Q and firm size and positively related to proxies for monitoring costs, which also influence the probability of launching premium ESOPs. Our results also show that the premium (out-of-the-moneyness) is negatively related to prior stock returns and cash flow-to-assets, which may be an indication of high-water mark contracting, or alternatively, of managerial power. Finally, we also find some support for a positive relation between the premium and the length of the vesting period when maturity is fixed, which indicates an effort to keep the incentives for management from falling over time.  相似文献

In this paper, redistributive transfers between regions are examined in a political economy model where both parties and voters are led by selfish as well as ideological motives, the latter taking the form of egalitarian objectives. Parties announce election platforms about how to distribute funds between regions and different income types, and voters react to these platforms when casting their vote. It is found that regional transfers are completely tactical; it is the political power of a region that decides if it will be a receiver or a contributor. Ideological goals are reached by redistributive transfers between different income types.  相似文献

What’s Trade Got to Do with It? Relative Demand for Skills within Swedish Manufacturing. — This paper seeks to identify the contribution of trade and technological change to the increase in inequality between skilled and unskilled workers in Sweden since the 1970s. An empirical approach is adopted which allows for the outsourcing of the low-skill parts of the production chain to low-wage locations and is applied to detailed industry and bilateral trade data, the latter distinguishing between low-wage sources of imports and OECD countries. The paper finds that, in contrast to previous studies, trade with low-wage countries may have contributed to the rise in inequality in Swedish manufacturing. The empirical results also suggest that the increased use of technology also played a role in creating greater inequality between skilled and unskilled workers in Sweden, with the magnitude of this impact increasing in the 1990s.  相似文献

International Financial Reporting Standards (IFRS) are required for consolidated financial statements of all European Union (EU) publicly traded companies starting from the December 2005 fiscal year end [Regulation (EC)]; and endorsed by the International Organization of Securities Commission (IOSCO) for its member countries beginning in 2000. We examine the challenges and benefits, including value relevance, of the adoption of IFRS by DAX‐30 companies, the German premium stock market. Based on a survey sent to DAX‐30 company executives, we find most companies agreeing that implementing IFRS should improve the comparability of financial statements. The complex nature, high cost of adopting and lack of guidance for implementing IFRS, as well as increased volatility of earnings after adopting IFRS, are listed among the most important challenges of conversion to IFRS. We use regression to measure another benefit: the value relevance of book values of earnings and equity in explaining market values of DAX‐30 companies during the period 1995–2004. Using 265 observations, we find that adopting IFRS or US Generally Accepted Accounting Principles or cross‐listing on the New York Stock Exchange significantly increases the value relevance of earnings relative to market prices.  相似文献

Die geldpolitische Strategie der Europäischen Zentralbank beruht auf der wirtschaftlichen und der monetären Analyse von Risiken für die Preisstabilität im Euroraum.

The principal component regression (PCR) is often used to forecast macroeconomic variables when there are many predictors. In this letter, we argue that it makes sense to pre-whiten the predictors before including these in a PCR. With simulation experiments, we show that without such pre-whitening, spurious principal components can appear and that these can become spuriously significant in a PCR. With an illustration to annual inflation rates for five African countries, we show that non-spurious principal components can be genuinely relevant in empirical forecasting models.  相似文献
