Human capital and economic development

This paper develops a general equilibrium model of fertility and human capital investment with young adult mortality. Because young adult mortality is negatively related to average young adult human capital, human capital accumulation lowers mortality, inducing demographic transition and industrial revolution. Data confirm that young adult mortality is related negatively to schooling, and the rate of return to schooling, and positively to fertility. The data indicate a negative relationship between TFP growth and schooling accumulation. The model fits the data on country populations, per capita incomes, human capital, total fertility rates, infant mortality, life expectancy and conditional life expectancy.     

Structuring technological information for technology roadmapping: data mining approach

Most research on technology roadmapping has focused on its practical applications and the development of methods to enhance its operational process. Thus, despite a demand for well-supported, systematic information, little attention has been paid to how/which information can be utilised in technology roadmapping. Therefore, this paper aims at proposing a methodology to structure technological information in order to facilitate the process. To this end, eight methods are suggested to provide useful information for technology roadmapping: summary, information extraction, clustering, mapping, navigation, linking, indicators and comparison. This research identifies the characteristics of significant data that can potentially be used in roadmapping, and presents an approach to extracting important information from such raw data through various data mining techniques including text mining, multi-dimensional scaling and K-means clustering. In addition, this paper explains how this approach can be applied in each step of roadmapping. The proposed approach is applied to develop a roadmap of radio-frequency identification (RFID) technology to illustrate the process practically.     

Nineteenth Century Urban Market Failure?: Chadwick on Funeral Industry Regulation

This essay analyzes the regulatory theory and policy preceptions of Edwin Chadwick (1800-1890), the premier Benthamite utilitarian reformer. We focus on and analyze Chadwicks economic diagnosis of the London funeral market in the first half of the nineteenth century. In his view, externalities and market failure in both the burial and funeral service markets demanded socialization of property rights and implementation of a franchise bidding scheme. Chadwicks rationales for government intervention, including high taxes and information costs—unique, we believe, for his time—provide the basis for numerous forms of contemporary regulations at all levels in the United States today.     

Mapping and analysing virtual outcrops

Laser scanning is a very efficient way to generate realistic, high-resolution digital models of 3-D geological outcrops. This paper discusses the methodologies involved in the creation and analysis of virtual outcrops, based on laser scanner data. The visualisation of the laser scanner data as a photorealistic 3-D object is described. Geological features picked out on the virtual outcrop (e.g. fractures, faults or bedding planes) can be extrapolated outward, into space, and inward, into the subsurface, using tension surfaces.     

Exogenous and Endogenous Attention and the Convergence of Analysts’ Forecasts

The propensity of the forecasts of sell-side financial analysts to converge (or diverge) is a function of their exogenous and endogenous selective attention and overconfidence. When returns are negative, the endogenous form of selective attention—a static measure of analysts’ goal-driven attention at a particular point in time—has a positive association with convergence. The exogenous form of selective attention—a relatively involuntary dynamic process of exogenous attentional shift driven by external changes in the market over time—is associated with a tendency for forecasts to diverge.     

Growth and Nongrowth Capital Investments and Future Performance*

Most studies on the impact of capital expenditure on future performance use the aggregate capital expenditure disclosed in the cash flow statement. In this study, however, we distinguish between growth capital investments (that increase production capacity) from nongrowth capital investments (that only maintain or reduce current capacity). For growth capital investments, we document a negative association with year-ahead performance, which becomes positive in the subsequent year. For nongrowth capital investments, we observe a non-negative association with year-ahead performance. For nongrowth capital investments, we document a positive association, suggesting that the divestment is beneficial. That is, firms are likely disposing of nonproductive assets. Our results suggest that disclosing the nature of capital investments is important to better assess the future impact of a firm's investment decisions.     

Comparative evaluation of a teaching innovation in accounting education: intensive learning in a seminar format

This paper reports a teaching innovation involving intensive learning and the evaluation of that innovation. A review of the literature reveals a lack of research about how effective intensive programmes are in enhancing student learning. In this study the performance of students studying accounting during an intensive summer-school in seminar format was compared with those studying during the regular semester in a lecture and tutorial format. Performance was compared by reference to students' grades and the understanding and retention of a key concept in the subject. Student study habits and the experiences of staff and students who participated in the summer-school were also evaluated. This study concluded that summer-school students' performance was better than regular semester students in the accounting subject studied. Their performance was equivalent or better than the regular semester students in the three other subjects studied in first semester. Summer-school students demonstrated a more complete understanding of a key concept than did the students in the regular semester, with this difference sustained after two years. There was a positive response to the summer-school by those staff and students who participated.     

Socially Useless Jobs

Recent research suggests that many workers in modern economies think that their job is socially useless, i.e., that it makes no or a negative contribution to society. However, the evidence so far is mainly anecdotal. We use a representative dataset comprising 100,000 workers from forty‐seven countries at four points in time. We find that approximately 8 percent of workers perceive their job as socially useless, while another 17 percent are doubtful about the usefulness of their job. There are sizeable differences among countries, sectors, occupations, and age groups, but no trend over time. A vast majority of workers cares about holding a socially useful job and we find that they suffer when they consider their job useless. We also explore possible causes of socially useless jobs, including bad management, strict job protection legislation, harmful economic activities, labor hoarding, and division of labor.     

Capital Market Development,Competition, Property Rights,and the Value of Insurer Product‐Line Diversification: A Cross‐Country Analysis

In this article, we show that the effect of product diversification on performance is not homogeneous across countries. Diversified insurance companies perform significantly worse than their focused competitors in countries with well‐developed capital markets, high levels of property rights protection, and high levels of competition. In addition, we find that the diversification–performance relationship for insurance companies depends on company size. For large insurers operating in countries with less developed capital markets, diversification significantly increases performance. Our results suggest that the optimal organizational structure may be different for insurers operating in emerging economies than for insurers operating in developed countries.
