Lead Paint,Toxic Torts,and the Housing Stock: A Case Study in Risk Assessment

Numerous policymakers have accepted claims in the public health literature that the United States is in the middle of a serious epidemic of childhood lead poisoning, due primarily to lead paint in the housing stock. This article analyzes some of the most influential lead paint epidemiological studies from an economics perspective and finds evidence that the claimed effects of lead on intelligence, school success, and other outcomes may be grossly exaggerated. In addition, the main cost-benefit analysis used by policymakers to advocate lead paint abatement of the entire U.S. housing stock contains serious mathematical errors and strikingly implausible economic assumptions. A corrected model shows that the proposed national abatement policy is likely to yield no net benefit.     

Small business economics: A perspective from The Netherlands

Conclusion In the analysis of economic phenomena either within or across industries there is room for integrating the role of small business. This contribution can be made by aggregation or generalization of the findings at the meso level, which again are partly based upon analyses at the micro level.The Netherlands has a long history in macro model building. A recent discussion among Dutch macro-economists considered the future of econometric model building at the macro level, and considered how best to improve this model building. The explicit integration of scale effects, however, was not mentioned. I am convinced that improvements in this respect are possible. In particular, I have in mind the role which small businesses play in certain areas such as wage structure, employment or investments. The dissection of macro prognoses into a small business component and a remaining component is a traditional practice in The Netherlands. Finally, there is much concern in The Netherlands for the calculation of regulatory effects, decomposed into effects for small and large businesses. If anywhere in the world there is a solid foundation for studying scale effects in both macro and sectoral models, it most certainly has been in The Netherlands. There is a strong tradition of macro-econometric model building; groups of econometricians specialized in small business research exist; Dutch policymakers show concern and the required research apparatus is available.

Conditional Dependence in Precious Metal Prices

This study investigates the time-series properties of gold and silver spot prices. Both precious metal price series are found to exhibit time dependence and pronounced generalized autoregressive conditional heteroscedastic (GARCH) effects. Splitting the data into similar economic subperiods provides superior explanation of these effects because of the observed long-run nonconstancy of the unconditional variance. Further, the power exponential distribution, as opposed to the Student-t, is found to portray accurately the thick-tailed conditional variance that remains after the GARCH effects are removed. These findings imply that constant variance pricing models are inappropriate for securities that are based on precious metal prices.     

WHAT ATTRACTS FOREIGN DIRECT INVESTMENT: A CLOSER LOOK

It is rational to assume that minimal trade barriers (tariffs and quotas), a bigger trade sector, lower interest rate regulations, freer international capital market, lower credit and labour market regulations will make investment in a country more lucrative for foreign investors. We confirm this and show the prevalence of non-linearity in the relationships.     

Persuasive devices

This paper addresses the devices by which we persuade in thediscipline—to produce and reproduce representations ofeconomies that focus on atomistic individuals, freedom of choiceand closed systems. By means of these devices we erase fromour perceptual field those characteristics of the economic realmthat consider elements of the social nature of individuals,open system thinking, relationality and relative power, includingthe influence played by income and wealth distribution.     

PRIVATE EQUITY: SOURCES AND USES

Private equity capital is playing a large and growing role in the funding of small to medium-sized, high-growth businesses. Today's private equity investment typically takes the form of purchase of a minority interest in a post-start-up, high-technology company followed by an IPO a few years later. A large number of such investors are scouring the markets for new investment possibilities and the competitive pressures are growing.
Although private equity investors can and often do add significant value to a company, private equity is potentially expensive, in terms of both loss of ownership and loss of control over long-term strategic decisions of the company. Owner-managers who want to retain as much of both as possible are advised to install more formalized business procedures, expand the company's outside relationships, and become more familiar with the company's financial needs and options. These changes should reduce capital needs, reduce the costs of private equity funding, and increase negotiating leverage when dealing with large, sophisticated private capital investors.
