An empirical investigation of international asset pricing

We investigate several asset pricing models in an internationalsetting. We use data on a large number of assets traded in theUnited States, Japan, the United Kingdom, and France. The modeltogether with the hypothesis of capital market integration implytestable restrictions on multivariate regressions relating assetreturns to various benchmark portfolios. We find that multifactormodels tend to outperform single-index models in both domesticand international forms especially in their ability to explainseasonality in asset returns. We also find that the behaviorof the models is affected by change in the regulatory environmentin international markets.     

Estimating the South African trauma caseload

A survey of medical superintendents revealed that an estimated 1.5 million trauma cases presented to South Africa's 356 secondary and tertiary level hospitals in 1999. Injury rates for traffic, violence and other injuries showed considerable inter-provincial variation, with violence accounting for more than half of the trauma caseload. This type of survey is a simple low cost alternative for monitoring injury patterns and supplementing burden of disease and injury costing studies.     

The capital structure puzzle revisited

Corporate finance researchers have long been puzzled by lowcorporate debt ratios given debt's corporate tax advantage.This article recognizes that firm value typically reflects agrowing stream of earnings, while current debt reflects a nongrowingstream of interest payments. Debt to value is therefore a distortedmeasure of corporate tax shielding. Even with very small debt-relatedcosts, this may explain the observed magnitude and cross-sectionalvariation of debt ratios. Since this variation may be independentof tax shielding, debt ratios provide an inappropriate frameworkfor empirically examining the trade-off theory of capital structure.     

Exploring consumers' preferences with regard to department and specialist food stores

Consumers' lifestyle changes and striving towards better time management have resulted in the greater choice they are offered with regard to store formats. Therefore, this study was undertaken to identify the factors that influence consumers in their patronage of a particular store format and to categorize department and specialist food store consumers according to their preferences in store layout and product range in a South African context. A qualitative research approach was used and data were collected using semi‐structured interviews with open‐ended questions. Purposive sampling recruited participants shopping for food in a department store in Johannesburg. Forty semi‐structured interviews were conducted before data saturation was reached. Store‐related factors such as store location, appearance and hygiene, service quality, convenience of trading hours, and consistency in store layout predominantly influenced participants in their patronage of a specific store format. Furthermore, product‐related factors such as quality, price, product range and convenient packaging enhanced consumers' store preference. Department store consumers were orientated towards one‐stop shopping and time‐saving strategies, while specialist food consumers were focused on food shopping and the trading hours of the store. Although similarities in participants' preferences with regard to department and specialist food store were found, different preferences were found regarding the placement of specific items within the store. Participants had similar preferences regarding the product range of a food store. However, department store participants emphasized the provision of convenience food and non‐food items. The findings of this study are valuable in providing department and specialist food store retailers with guideline recommendations regarding store layout and product range in order to effectively respond to the needs and preferences of consumers within an emerging economy.     

Underestimation of portfolio insurance and the crash of October 1987

We examine market crashes in the multiperiod framework of Glostenand Milgrom (1985). Our analysis shows that if the market'sprior beliefs underestimate the extent of dynamic hedging strategiessuch as portfolio insurance, then the price will be greaterthan that which would be implied by fundamentals if the extentof portfolio insurance were known with certainty. Over time,the market learns of the amount of portfolio insurance, andconsequently reevaluates the previous inferences drawn frompurchases that were erroneously regarded as based on favorableinformation. The result is that the price falls when the amountof portfolio insurance is revealed.     

Restrictive Macroeconomic Policies and Unemployment in the European Union

This paper looks at the impact the European integration process has had on the unemployment level of European Union member countries. While the persistence of relatively high unemployment in Europe is often attributed to supply-side factors, such as the rigidities of the labour market, this study contends that the major cause for the rise of unemployment in the EU has been the very macroeconomic policies of the EU itself. The paper argues that the continuous pursuit of deflationary policies and the macroeconomic constraint imposed first by the membership of the European Monetary System and, secondly, by the convergence criteria of the Maastricht Treaty, have been the real impediments to reducing unemployment.     

Time-varying risk and return in the bond market: a test of a new equilibrium pricing model

This article uses bond market data to empirically test the assetpricing model of Kazemi (1992). According to this model therate of return on a long-term, pure-discount, default-free bondwill be perfectly correlated with changes in the marginal utilityof the representative investor. The covariability between financialasset returns and returns on such a bond can therefore serveas a measure of the riskiness of assets. The aim of this studyis to determine whether the model can explain cross-sectionaldifferences in the monthly returns of bonds with different maturitydates. We estimate and test the restrictions imposed by themodel on returns of default-free bonds, while allowing the conditionaldistribution of bond returns to be time varying. The model isrejected during the full sample period (1973-1995) and the subperiod(1973-1980) when the Federal Reserve's focus is on interestrates, while the model is not rejected during the subperiod(1981-1995) when the Federal Reserve's focus is on money supply.
