Does health insurance decrease health expenditure risk in developing countries? The case of China

This article studies the impact of health insurance on individual out‐of‐pocket health expenditures in China. Using China Health and Nutrition Survey data between 1991 and 2006, we apply two‐part and sample selection models to address issues caused by censored data and selection on unobservables. We find that, although the probability of accessing health care increases with the availability of health insurance, the level of out‐of‐pocket health expenditure decreases. Our results from a selection model with instrumental variables suggest that having health insurance reduces the expected out‐of‐pocket health expenditure of an individual by 29.42% unconditionally. Meanwhile, conditional on being subjected to positive health expenditure, health insurance helps reduce out‐of‐pocket spending by 44.38%. This beneficial effect of health insurance weakens over time, which may be attributable to increases in the coinsurance rates of health insurances in China.     

A note on estimating the divisional cost of capital for diversified companies: an empirical evaluation of heuristic-based approaches

This note provides an empirical analysis of the potential for heuristic-based approaches to derive a divisional cost of equity from a firm's total cost of capital. Since an empirical relationship between fundamental information and systematic risk has previously been shown in other studies, idiosyncratic information on risk and performance ought to serve as a good proxy to calculate divisional adjustments. Two practically used, heuristic-based approaches are tested and a significant relationship is found between one of the measures and CAPM beta. This method may offer a plausible and comparatively uncomplicated method for adjusting a firm's total cost of capital for divisional use.

The determinants of federal and state enforcement of workplace safety regulations: OSHA inspections 1990–2010

We explore the determinants of inspection outcomes across 1.6 million Occupational Safety and Health Agency (OSHA) audits from 1990 through 2010. We find that discretion in enforcement differs in state and federally conducted inspections. State agencies are more sensitive to local economic conditions, finding fewer standard violations and fewer serious violations as unemployment increases. Larger companies receive greater lenience in multiple dimensions. Inspector issued fines and final fines, after negotiated reductions, are both smaller during Republican presidencies. Quantile regression analysis reveals that Presidential and Congressional party affiliations have their greatest impact on the largest negotiated reductions in fines.     

The Role of Speculation and Information in the Early Evolution of the United States Ostrich Industry: An Industry Case Study

The U.S. ostrich industry was introduced in the 1980s and experienced rapid expansion in the late 1980s and early 1990s. Breeding stock prices rose rapidly and subsequently plummeted during 1993–1995. High prices are to be expected in the introductory stage of an industry. However, the magnitude of prices in the ostrich industry is likely due to overestimates of ostrich productivity and future demand for ostrich products, as well as speculation in the ostrich market. This paper discusses the evolution of the industry from the mid-1980s to the present.     

German dominance in the EMS

The paper assesses the merit of the view according to which the Bundesbank dominates monetary policy-making in the European Monetary System. Our tests give a strong rejection of German dominance and suggest, instead, that monetary policymaking in the EMS is interactive. There is evidence that the Bundesbank pursues her own policy goals in the longer run. But German independence does not imply German dominance.
