This article examines the responsiveness of real output to the variability of inflation and aggregate demand. In the manner of Lucas (1973), estimates of the output-inflation tradeoff are computed for a large sample of countries. This measure is then correlated with the variances of the inflation rate and the growth rate in nominal income. Because differences in inflation variance (and hence the tradeoff) are viewed as the outcomes of differences in demand variance, correlations between these two variables are also reported. Cross-time and cross-country results provide a good measure of support for Lucas and the notion that attempts to exploit the tradeoff weaken it.  相似文献

De George's understanding of theology is limited to one of five commonly recognized models of theology, the orthodox model. This model is vulnerable to De George's criticisms. When religious ethics operates out of the revisionist model of theology, however, his criticisms lose their sting. Revisionist religious ethics, moreover, can make a fruitful contribution to business ethics. Such a religious ethic acknowledges the embodiment dimension of business activities, it complements philosophical analysis with the practice of moral discernment, and it recognizes irony as an active component in decision-making.John T. Leahy is an Associate Professor of Religious Studies at DePaul University.  相似文献

The social spotlight seems to be refocusing to the scale of local community at a time when globalisation of the economy is threatening the authority of nation-states. Certain small communities are in peril of falling out of the global economy while losing local customs to a globalised culture. Globally beleaguered nation-states are being squeezed in a two-pronged grip: from the growing weight of global capital and from local communities rising to global pressures by demanding local solutions. National authority is also being bypassed as new global communities of interest form on the Internet, expanding the meaning of the term community. But, is community more than common interest—a celebration of difference, negotiating symbiosis among diversity of ethnicity, lifestyle and aspirations for the future? This paper explores five scenarios of tomorrow’s communities. One scenario is a nostalgic return to the romantic notion of the white-picket fence. Then there is the drop-out feral community. In another future the fence becomes a fortress wall, or a ring of barbed wire. Yet another is a virtual community beyond place, where people sharing a common interest live in cyber-reality. The viable community is one for the long haul. To be viable in a global world it must make local-global links to create synergies by sharing resources and inspirations throughout a diverse, planetary society. Viable, local-global network communities of tomorrow set a global example for creativity by honouring difference and open exchange. They take responsibility for their own futures.Two powerful images from recent events remain with me, in juxtaposition. After considering the American attacks on Afghanistan, a well-experienced teacher feels isolated at the periphery, and powerless. In addition, she watches, in “quiet despair”, one of her pupils “virtually going crazy” before her eyes. She shares these words with me:
“Neither he nor I, it seems, have anywhere to run except to the graciousness and the care of the other children, that as classroom leader I’m tying daily to coalesce, in order to put a cocoon of community around him. Bit like the planet!”
“We all work to keep our very bright and fairly disturbed ADHD-labelled1 learner connected to us in genuine relationship. That’s the foundation of authentic learning support. I’m not operating a medical model!”
Our leaders and the babbling mass media ignore this, the first image, and many similar to it.By contrast, the second image gets constant exposure. It gets instant recall from most TV viewers. It is the scramble of screen jockeys, on what is left of Wall Street, playing the casino economy, in a frenzy of greed. Curiously the main media focus emphasizes images that represent the world at the global scale. They largely ignore images of life at the scale of community.Why is this? Why does the second image of the so-called finance community, where the focus is the dollar, override the more basic image of a hometown community where the focus is human life-support? Are the media reflecting our true priorities, and have we got it wrong? Is money more important than community?  相似文献

The intrinsic value approach amortizes over the life of the option, the difference between the stock price on the date of the grant and the exercise price of the option. The fair market value approach amortizes over the life of the option, the market value of stock options on the date of the grant. These approaches do not reflect the changes in the option–based compensation cost after the grant date. This paper proposes an economic cost approach that not only adjusts for the changes in the value of the options during its life but also records the issuance of the stock at fair market value on the exercise date.  相似文献

This paper examines the influence of unemployment insurance (UI) on the length of nonemployment spells experienced by young workers. The analysis introduces a flexible duration model to estimate the effects of the weekly benefit amount and weeks of eligibility on the amount of time spent between jobs by men, distinguishing between the experiences of UI and non-UI recipients. The empirical findings suggest three conclusions: (1) UI recipients experience longer spells of nonemployment than their non-UI recipient counterparts, at least up to the point of exhaustion of UI benefits; (2) the level of the weekly benefit amount does not significantly affect the length of nonemployment spells; and (3) increasing the number of weeks of eligibility offered by a UI program leads to longer episodes of nonemployment.  相似文献

Much of the debate about rising health care costs in the United States centers on the notion of "cost shifting." Cost shifting is loosely defined as charging one set of patients a higher price to offset losses on another set of patients. One aspect of the cost shifting debate that the empirical work has ignored is whether or not doctors—as opposed to hospitals—practice cost shifting. The analysis here investigates this question using the Physicians' Practice Costs and Income Survey, 1983–1985 (PPCIS, expanded version)
Using variation across states in Medicaid reimbursements, the analysis finds that lower Medicaid reimbursements tend to lower the fees physicians charge, contradicting the standard cost shifting story. Evidence also suggests that lower Medicaid reimbursements tend to cause physicians to treat fewer Medicaid patients. These results are consistent with profit maximizing behavior for physicians and also with the hypothesis that physicians exert some monopoly power.  相似文献

This article investigates the relationship between a debtor country's external financial indicators and the costs associated with the insurance of export credits to that country. For this purpose a stylized model of export credit insurance (ECI) is developed, the central idea being that ECI is similar to a contingent claim such as a European put option. Thus, tools from option pricing theory were used to calculate the price of ECI, implying that not only the current financial position but also the volatility of the changes in that position determine such costs. The empirical results of a statistical analysis of the premium rates for ECI, applied by a private export credit insurer to seventy-seven developing countries during 1993, provide some support for these hypotheses. In particular, the reserves-over-imports ratio of a debtor country and the volatility of the rates of change of this ratio appear to contribute significantly to the premium rates that apply to that country. Thus, the article provides evidence that option pricing parameters do play role in practical insurance pricing, even if this pricing is not explicitly based on these parameters. Premium rates are set as if an underlying option market operated. Thus, the trade of countries with volatile external financial positions is saddled with higher costs than that of countries with more stable positions.  相似文献
