Post Keynesian economics has mainly focused on macroeconomic issues and ignored microeconomic policy issues. This paper begins to remedy this gap. It outlines the main principles of the Post Keynesian approach, distinguishes them from neoclassical economics, explains how these principles can be applied to microeconomic issues, and then draws out some policy implications that differ markedly from neoclassical theory on the issues of health care and productivity growth.  相似文献

This paper describes the construction of a data set of the Polish power sector for use with the Elfin capacity expansion planning model. Using Elfin, the paper derives four scenarios and some sensitivities for new generating capacity construction plans. These scenarios simulate choices among several generic generating technologies made to achieve the lowest overall net present cost of operating the power system through 2015. Key results include: (i) single-cycle natural gas-fired combustion turbines prove highly attractive for Poland because of its urgent need for peaking capacity, (ii) nuclear power cannot be excluded from consideration for Poland on economic grounds alone, (iii) the effectiveness of conservation to reduce airborne emissions is limited under scenarios in which nuclear generation is adopted, and (iv) the attractiveness of nuclear is shown to be highly sensitive to assumptions on some uncertain inputs, suggesting the need for a more detailed analysis before policy implications can be drawn.  相似文献

Longer life expectancy and declining birth rates have contributed to an aging population in many countries. This paper addresses the relationship between mental health and employment status among the elderly in Taiwan. A simultaneous equation system is developed that accommodates the discrete and censored nature of the two endogenous variables. Using data from a nationwide survey of the elderly in Taiwan, we find that older adults with mental illness are less likely to work, while those currently working are less prone to mental illness compared to their unemployed cohort.  相似文献

We design an incentivized experiment to test whether measurement uncertainty elevates the risk that social bonds between auditors and reporters compromise audit adjustments. Results indicate that, when audit evidence is characterized by some residual uncertainty, the adjustments our auditor‐participants require are sensitive to whether auditors have an opportunity to form a modest but friendly social bond with reporters. In contrast, although auditors do not adjust fully even when misstatements are known with certainty, social bonding has no effect in this scenario. Accordingly, our experiment contributes beyond the main effects of social bonding and measurement uncertainty demonstrated in prior research by showing that these forces interact. A practical implication is that regulators and practitioners should consider both the technical and the social challenges facing audits of complex estimates.  相似文献

The variability of producers ‘net income levels is largely a function of variability in output price, yield, and input prices. Yet, the tools available to manage price risk and yield risk are not widely used by producers. Is the market failing to provide agricultural producers with effective risk management tools? To identify producers’ needs, the paper establishes the relative importance of price and yield risk by decomposing the variability of revenues from a sample of crops in California agriculture. The risk tools available to producers of those commodities are compared to producers needs for tools. Results indicate that “market failure” is readily apparent in markets for tools to manage risks. However, the nature of these missing or incomplete markets does not necessarily imply inefficiencies that would justify government intervention.  相似文献

A comparison of three different detergents was made by evaluating their properties of soil removal, soil redeposition and calcium carbonate deposition. The detergents included a phosphate granular detergent, a non-phosphate, carbonate built granular detergent and an unbuilt liquid detergent. The local water conditions were moderately hard and clay type soils were used. Detergency was evaluated on the basis of both visual and instrumental colour changes. In effecting soil removal, clay stained fabrics laundered with the phosphate detergent retained only a small amount of soil, while fabrics laundered with the two non-phosphate detergents showed heavier staining. In preventing soil redeposition, the phosphate detergent produced almost no visible redeposition; the unbuilt and carbonate built detergents ranked correspondingly lower. In assessing calcium carbonate deposition, the phosphate and unbuilt detergents showed little or no change, while the carbonate detergent continued to build up deposits with laundering. In summary, the phosphate detergent ranked highest in overall performance, with correspondingly lesser performance from the unbuilt and carbonate detergents.  相似文献

Vanity is a psychological construct that describes a person's excessive concern with physical appearance or achievement. A scale, recently developed to measure this construct, has been psychometrically validated using data from U.S. respondents. The goal of this paper is to determine if this scale can be used cross‐culturally. If the scale has cross‐cultural applicability, it can be used as a counseling device to guide and alert individuals to certain tendencies. The scale also can be used to track foreign cultures as they adopt a consumerism ethos more aligned to Western consumer culture. Based on data from 475 young adults in China, India, New Zealand, and the U.S., the scale was found to have similar dimensionality and factor structure, internal consistency, discriminant validity, and metric invariance. Implications and future directions for research are discussed.  相似文献

Microfinance institutions (MFIs) play a key role in many developing countries. Utilizing data from Eastern Europe and Central Asia, MFIs are found to generally operate with lower costs the longer they are in operation. Given the differences in operating environments, subsidies, and organizational form, this finding of increasing cost effectiveness may not aptly characterize all MFIs. Estimation of a mixture model reveals that roughly half of the MFIs are able to operate with reduced costs over time, while half do not. Among other things, we find that larger MFIs offering deposits and those receiving lower subsidies operate more cost effectively over time.  相似文献
