An investigation is reported of the potential for reducing aggregate medical costs by the introduction of nurse practitioners into the Canadian health care system to an extent consistent with demonstrated safety and effectiveness. A cost model is developed for this purpose and estimates of its parameters are provided. The cost model is coupled with a demographic projection model and potential cost reductions are simulated over the period 1980-2050, under alternative assumptions. Results suggest that savings could have been in the range 10-15% in 1980 for medical services as a whole, and 16-24% for ambulatory services. The estimated savings percentages are quite insensitive to projected changes in the age structure of the Canadian population. 相似文献

This study empirically investigates the information dynamics of the Ohlson valuation framework. Single-period lagged linear autoregressive relationships among dividends, earnings, and book values of equity are estimated for a sample of stochastically stationary firms and are found not to support the valuation framework. This study further extends the empirical analysis to a multilagged vector autoregressive linear information system. Consistent with the Ohlson valuation framework,the past time series of all three variables are generally found to be relevant for firm valuation. This study brings into question empirical research utilizing the Ohlson framework that presupposes a single-period lagged information dynamic. 相似文献

Successful deregulation of financial institutions promotes flexibility and effeciency while avoiding the instabilities and abuses that characterized the financial system prior to the reform legislation of the 1930s. It is essential that deregulation nut undermine the efficacy of deposit insurance. The growth of money market funds has already resulted in a shift from insured to uninsured accounts. With deregulation there will be much larger shifts of funds to uninsured transactios accounts. In a deregulated world, it is essential that insurance be extended to cover transactions accounts, no matter who issues them, The paper also asserts that existing statutes are inadequate to deal with the conflicts of interest and anti-competitive practices that are likely to occur with deregulation. Safeguards should be established before deregulation goes any further. Finally, it is argued that in a deregulated environment, most forms of money will pay interest, and required reserves will disappear. While these developments will not destroy the efficacy of monetary policy, they will affect it. Little work has been done an the issue of monetary policy in a deregulated world. The paper discusses existing studies and suggests some topics for future research. 相似文献
