The Human Capital Value of OOP

If object-oriented programmers are more productive than other programmers, they should be paid more, assuming that wages are determined based on the value of a worker\u27s marginal productivity. The human capital model is used to assess the current salary premiums of programmers who know object-oriented programming (OOP). While the human capital model employed quantifies this premium, it also controls for the effects of different amounts of technical experience and different levels of education (highest attained degree) that the programmers possess. Using two samples, the incremental value of OOP skills is shown to be about the same over the two different time periods (2000/2001 and 2003)

The Impact of Medical and Nursing Home Expenses and Social Insurance Policies on Savings and Inequality

We consider a life-cycle model with idiosyncratic risk in labor earnings, out-of-pocket medical and nursing home expenses, and survival. Partial insurance is available through welfare, Medicaid, and social security. Calibrating the model to the U.S., we find that nursing home expenses play an important role in the savings of the wealthy. In our policy analysis, we find that elimination of out-of-pocket expenses through public health care would reduce the capital stock by 12 percent, Medicaid and old-age welfare programs crowd out 44 percent of savings and greatly increase wealth inequality, and social security effects are influenced by out-of-pocket health expenses.social insurance; medical expenses, nursing home expenses; wealth inequality; savings

The impact of medical and nursing home expenses and social insurance

We consider a life-cycle model with idiosyncratic risk in labor earnings, out-of-pocket medical and nursing home expenses, and survival. Partial insurance is available through welfare, Medicaid, and social security. Calibrating the model to the United States, we find that 12 percent of aggregate savings is accumulated to finance and self-insure against old-age health expenses given the absence of complete public health care for the elderly and that nursing home expenses play an important role in the savings of the wealthy and on aggregate. Moreover, we find that the aggregate and distributional effects of public health care provision are highly dependent on the availability of other programs making up the social insurance system.

Financing Healthcare Services for the Poor

This paper was written as part of Shujog Research's Financial Innovation for Poverty Reduction Series. It studies the challenges and gaps in the funding of healthcare provision in Asia, and evaluates several innovative financing solutions that can help countries achieve the goal of universal access to healthcare

Natural‐language processing applied to an ITS interface

The aim of this paper is to show that with a subset of a natural language, simple systems running on PCs can be developed that can nevertheless be an effective tool for interfacing purposes in the building of an Intelligent Tutoring System (ITS). After presenting the special characteristics of the Smalltalk/V language, which provides an appropriate environment for the development of an interface, the overall architecture of the interface module is discussed. We then show how sentences are parsed by the interface, and how interaction takes place with the user. The knowledge‐acquisition phase is subsequently described. Finally, some excerpts from a tutoring session concerned with elementary geometry are discussed, and some of the problems and limitations of the approach are illustrated

The Influence of Public Policy on Health, Wealth and Mortality

In this project we extend an augmented lifecycle model, incorporating a Grossman-style model of health capital, to enhance understanding of factors influencing consumption, wealth and health. We develop three primary results when using the model to explore the effects of stylized versions of Medicare and Social Security on wealth and longevity. First, our model calibration implies consumption and health are complements. As health depreciates with age, households will get less utility from consumption than would be in the case of a lifecycle model that does not endogenize health. Second, it appears that forward-looking households, when confronted by a substantially reduced safety net, will respond by reducing consumption and by reducing their health investment and therefore longevity. Third, there is a potentially important difference between short- and long- run responses to policy.

Health and Wealth in a Life Cycle Model

This paper presents a preliminary model of health investments over the life cycle. Health affects both longevity and provides flow utility. We analyze the interplay between consumption choices and investments in health by solving each household’s dynamic optimization problem to obtain predictions on health investments and consumption choices over the lifecycle. Our preliminary model does a good job of matching the distribution of medical expenses across households in the sample. We illustrate the scope of future model applications by examining the effects of a stylized Medicare program on patterns of wealth and mortality.

Can insurance reduce catastrophic out-of-pocket health expenditure?

In India, the out-of-pocket health expenditure by households accounts for around 70 percent of the total expenditure on health. Large out-of-pocket payments may reduce consumption expenditure on other goods and services and push households into poverty. Recently, health insurance has been considered as one of the possible instruments in reducing impoverishing effects of large out-of-pocket health expenditure. In India, health insurance has limited coverage and the present paper studies whether it has been effective so far. Literature defines out-of-pocket health expenditure as catastrophic if its share in the household budget is more than some arbitrary threshold level. In the present paper, we argue that for households below poverty line any expenditure on health is catastrophic as they are unable to attain the subsistence level of consumption. Thus, we take zero percent as a threshold level to define catastrophic health expenditure and examine the impact of health insurance on probability of incurring catastrophic health expenditure.Out-of-pocket health expenditure, Catastrophic health expenditure, Health insurance

Persistence of outstanding performance and shareholder value among diversified firms: The impact of past performance, efficient internal capital market, and relatedness of business segments

The research domain that attempts to study the relationship between diversification and performance has not yet reached definitive and interpretable findings, and recent studies challenge the existence of a "diversification discount" and explain it partially by a data artefact. None of these studies centred their research on the question: does there exist a specific performance pattern among diversified firms? This research aims to identify persistence in performance heterogeneity by measuring the shareholder value creation of diversified firms using alternative indicators other than the excess value methodology. It also aims to measure the impact on the performance according to the degree of efficiency of the internal capital market and the degree of relatedness among business segments. A sample of 164 diversified firms with turnover higher than 1$ billion during the period 1999-2006 is examined. Because of the presence of the firm's specific effect and the length of the time series, the persistence performance is tested through the instrumental variables (IV) system generalized method of moments (GMM) dynamic panel data and the persistence of shareholder value creation and destruction is estimated according to different estimators from top tercile and lower tercile portfolios of diversified firms. Some diversified firms persistently create value as well as beat the market index while others persistently underperform. Finally, if the efficiency of the internal capital market gives certain explanatory power of the performance pattern, but limited compared to the past performance, important insights might be drawn from the findings that diversified firms with segments in many unrelated industries perform better than others in few industries or with a high number of segments; hence the inverted-U curvilinear relationship between diversification and performance is here not confirmed.diversification; performance persistence; internal capital market; relatedness obusiness segments;
