The risk management systems now used in investment analysis are based on Markowitz meanvariance optimization. Successful application depends on the accuracy with which market returns, risk, and correlation are predicted. Forecasting methods now commonly employed for this purpose rely on time-series approaches that generally ignore economic content. This article suggests that explicitly incorpor...

Economic Aspects of Human Cloning and Reprogenetics This paper analyses the economic issues associated with human cloning and new reproductive technologies. We analyze the incentives for human cloning and its implications for the long run distribution of skills and income. We analyse models of human cloning for different motives, focusing on those which tend to produce new human beings with imp...

n Contemporary studies indicate that teen pregnancy interferes with young women’s ability to graduate from high school and to enroll in and graduate from college. Conversely, planning, delaying and spacing births appears to help women achieve their education and career goals. Delaying a birth can also reduce the gap in pay that typically exists between working mothers and their childless peers ...

This study examines the impact of fluctuations in entry-level labor market conditions on the graduate school enrollment decisions of newly minted undergraduate degree holders. Using repeated cross-section data for recently graduated science and engineering undergraduates from the National Survey of Recent College Graduates, and state-level unemployment rates to measure entry-level labor market ...

We provide experimental evidence on the ability to detect deceit in a buyer-seller game with asymmetric information. Sellers have private information about the value of a good and sometimes have incentives to mislead buyers. We examine if buyers can spot deception in face-to-face encounters. We vary whether buyers can interrogate the seller and the contextual richness. The buyers' prediction ac...

Specifically, freedom and the ability to participate fully in economic governance, and in the corresponding democratic knowledge and learning processes, would reflect and be reflected by a parallel freedom and ability in communication. The issues are explored by comments on art, and o...

This paper considers the relative importance of improvements in economic status in explaining improvements in non-monetary measures of well-being during Vietnam's economic boom in the 1990s. This study finds that improvements in economic status can explain virtually all of the 20 percent increase in schooling attainment and most of the observed improvements in child nutrition and declines in ch...

The world’s poor, whether they live in dangerous urban slums or in the remote countryside, are often in dire need of food, clean water, and basic medications. So it might appear misguided to argue that mental health should be a primary rather than secondary concern in developing countries. But the reality is that mental health is not just a First World problem: disorders such as depression are ...

This paper concerns with a mathematical model considering customer satisfaction requirements in a supply chain. The model tradeoffs the supply chain ability to fulfill the customers’ requirements and the limited budget in a variety of production phases. The decisions made here help to determine the profit provider price and economic quantity while the effective supplier and priori requireme...
