The co-movement of stock markets in East Asia: Did the 1997–1998 Asian financial crisis really strengthen stock market integration?

This paper examines the integration and causality of interdependencies among seven major East Asian stock exchanges before, during, and after the 1997–1998 Asian financial crisis. For this purpose, we use daily stock market data from July 1, 1992 to June 30, 2003 in local currency as well as US dollar terms. The data reveal that the relationships among East Asian stock markets are time varying. While stock market interactions are limited before the Asian financial crisis, we find that Hong Kong and Singapore respond significantly to shocks in most other East Asian markets, including Shanghai and Shenzhen, during this crisis. After the crisis, shocks in Hong Kong and Singapore largely affect other East Asian stock markets, except for those in Mainland China. Finally, considering the role of the USA shows that it strongly influences stock returns in East Asia – except for Mainland China – in all periods, while the reverse does not hold true.     

An oligopoly model of ocean liner shipping

In this paper I develop a simultaneous equations oligopoly model of the regulated international ocean liner shipping industry. The firms act as a cartel to determine price jointly and then set their own quality levels to maximize individual profits. The cartel does not attain monopoly profits, because each conference member myopically determines quality without regard for overall cartel profits. The results indicate that an increase in the number of firms in the cartel will increase both cartel price and quality level. An increase in price will also lead to an increase in quality level.I would like to thank Professors Alamarin Phillips, Robert Summers, and Bruce Allen for their helpful comments on earlier research for my dissertation in the Economics Department of the University of Pennsylvania on which this work is based. I am especially grateful to Professor Lawrence J. White for his encouragement and valuable suggestions at various stages of my work.     

Housing-Price Cycles and Prepayment Rates of U.S. Mortgage Pools

Empirical mortgage prepayment models generally have trouble explaining differences in mortgage-prepayment speeds among pools with similar interest rates on the underlying mortgages. In this article, we model some of the sources of termination heterogeneity across mortgage pools, particularly the role of regional variations in housing prices in generating atypical prepayment speeds. Using a sample of Freddie Mac mortgage pools from 1991 to 1998, we compare two classes of empirical models: a rational option-pricing model using a backward-solving pricing algorithm and an empirical hazard model. In both empirical estimation strategies, we find evidence that differences in house-price dynamics across regions are an important source of between-pool heterogeneity. This finding is then shown to be robust to alternative ways of parameterizing pool heterogeneity in mortgage termination models.     

Futures studies comes of age: twenty-five years after The limits to growth

Twenty-five years ago, the publication of The limits to growth marked a period of accomplishments in the futures field. Today, futures studies is experiencing another burst of development and is ready to move more fully into mainstream intellectual life and the standard educational curriculum. In addition to continued work on methods, theory, and empirical research, the resolution of three issues might help persuade established academic communities of the serious purposes and sound intellectual contributions of futurists. They are (1) the adoption of an adequate theory of knowledge (critical realism is proposed), (2) the recognition that prediction does play a role in futures studies (so we can deal explicitly with the philosophical challenges it poses), and (3) the formulation and justification of core values (so we have a valid basis by which to judge the desirability of alternative futures). I propose a critical discourse among futurists in order to resolve each issue. The desire to make futures thinking a part of everyone's education is not, of course, mere futurist chauvinism, but is based on the conviction that futures studies has important contributions to make to human well-being.     

Free trade, factor returns, and factor accumulation

A model of development is studied in which physical capital and unskilled labor are good substitutes, and skilled labor is complementary to the resulting aggregate. Growth in a closed economy is compared with two open regimes. Inflows of physical capital only reduce the interest rate and raise both wage rates. The skilled wage rises more sharply, however, increasing the skill premium and accelerating human capital accumulation. Full integration with a larger and more developed neighbor also reduces the interest rate and raises both wage rates, but in this case the skill premium falls and human capital accumulation changes very little.     

Quality indicators for academic nursing primary care centers

ANCs, by definition, deliver more than clinical services to patients and communities. The unique identifier that separates ANCs from other primary care/ambulatory care centers is the educational service they offer to students and other faculty in the school of nursing to which they belong. Therefore, measuring the quality of an ANC must include a measurement of the educational properties that it possesses in addition to the usual quality measurements by such organizations as AAAHC, JCAHO, CHAP, and AAACN. Unless these properties are included and measured by an ANC, it becomes difficult to justify the existence of such a clinic within a school of nursing. ANCs are encouraged to develop quality evaluation programs aimed at evaluating the educational aspects as well as the administrative and clinical aspects of their operations.     

Targeting Child Labor in Debt Bondage: Evidence, Theory, and Policy Implications

Despite recent multilateral efforts to single out child laborin debt bondage as one of the worst forms of child labor, severalimportant questions have yet to be addressed: How pervasiveis the phenomenon? Are there systematic correlations betweenthe incidence of children in debt bondage and the economic,legislative, and financial development indicators of the economy?How does an understanding of these correlates affect the waynational and international policy measures aimed at targetingthis form of child labor are perceived? This article addresseseach of these questions. The empirical findings suggest strongcorrelation between the likelihood of the incidence of childlabor in debt bondage with the stage of development of an economy,the stage of financial development, and enforcement of corelabor rights. Building on this evidence, the article presentsa theoretical model that highlights the drawbacks and meritsof a number of policies aimed at putting checks on child laborin debt bondage.
