Most forms of macroeconomics today, whether Keynesian or monetarist, presuppose that problems of economic instability can be treated as errors in financial management. Neither fiscal nor monetary policy recognizes the existence of systemic faults in the real economy that result in overinvestment in durable capital that turns over slowly, in contrast to forms of capital that interact more frequently with land and labor. Only by removing serious distortions in microeconomic relations can macroeconomic problems be resolved. The current global economic crisis exemplifies the limitations of policies that ignore distortions in the rate of turnover of investment capital. 相似文献

In this paper, the authors develop contingent claims models of loan guarantees in various circumstances: (1) a fully guaranteed issue of non-callable coupon debt; (2) a partially guaranteed issue of non-callable coupon debt; (3) junior and senior non-callable debt with guarantees; (4) callable coupon debt with guarantees. Numerical solutions of the resulting valuation models are performed using the method of Markov chains. Tables and graphs of the resulting values of loan guarantees are provided. The paper concludes with suggestions for extensions of this approach to the valuation of loan guarantees. 相似文献

Within the United Nations, the United Nations Development Programme, United Nations Environment Programme and Office for the Coordination of Humanitarian Affairs have all highlighted climate risks as relevant to their work in areas affected by conflict, endorsing human security approaches as valid for mapping the relationships between climate stresses and conflict-related harm. While this policy interest has limited operational presence, I discuss salient assessments of climate vulnerability in (post)conflict areas, arguing that these agencies have applied a natural disaster rather than conflict regulation inflection of humanitarian reason. The former entails a biopolitical paradigm of disaster risk reduction, prescribing technical-managerial measures to build the resilience of vulnerable populations. This framing supports a depoliticised stance reflecting UN norms of neutrality and impartiality. I claim that this position nevertheless disregards its own geopolitical conditions and effects, which dilute the scope for international humanitarian law to assign responsibility for conflict-related harm. 相似文献

Agriculture is unique among economic sectors in the nature of impacts from climate change. The production activity that transforms inputs into agricultural outputs involves direct use of weather inputs (temperature, solar radiation available to the plant, and precipitation). Previous studies of the impacts of climate change on agriculture have reported substantial differences in outcomes such as prices, production, and trade arising from differences in model inputs and model specification. This article presents climate change results and underlying determinants from a model comparison exercise with 10 of the leading global economic models that include significant representation of agriculture. By harmonizing key drivers that include climate change effects, differences in model outcomes were reduced. The particular choice of climate change drivers for this comparison activity results in large and negative productivity effects. All models respond with higher prices. Producer behavior differs by model with some emphasizing area response and others yield response. Demand response is least important. The differences reflect both differences in model specification and perspectives on the future. The results from this study highlight the need to more fully compare the deep model parameters, to generate a call for a combination of econometric and validation studies to narrow the degree of uncertainty and variability in these parameters and to move to Monte Carlo type simulations to better map the contours of economic uncertainty. 相似文献

Are individuals expected utility maximizers? This question represents much more than academic curiosity. In a normative sense, at stake are the fundamental underpinnings of the bulk of the last half-century’s models of choice under uncertainty. From a positive perspective, the ubiquitous use of benefit-cost analysis across government agencies renders the expected utility maximization paradigm literally the only game in town. In this study, we advance the literature by exploring CEO’s preferences over small probability, high loss lotteries. Using undergraduate students as our experimental control group, we find that both our CEO and student subject pools exhibit frequent and large departures from expected utility theory. In addition, as the extreme payoffs become more likely CEOs exhibit greater aversion to risk. Our results suggest that use of the expected utility paradigm in decision making substantially underestimates society’s willingness to pay to reduce risk in small probability, high loss events. 相似文献
