Redesigning hospitals around patients and technology

Hospitals must drastically redesign themselves and revise their operations to be successful. Four major redesign initiatives will enable the traditional hospital to provide effective patient care while attaining its own profitability goals.     

A longitudinal study of the cause and consequences of changes in diversification in the U.S. pharmaceutical industry 1977–1986

The paper hypothesizes that diversification by firms based in the pharmaceutical industry during the 1977-86 time period was primarily undertaken to reduce the risks associated with being dependent upon a technologically dynamic environment. Consistent with this non-efficiency motive for diversification, declining economic performance is predicted. A longitudinal empirical analysis provides support for these propositions.     

Copyright Damages and Statistics

This paper discusses the statistical issues that arise in conducting an economic damages analysis in the context of a litigation matter involving copyrights. Calculating damages in copyright cases turns out to be a natural application for econometric modelling methods. Surprisingly, elementary statistical issues can be a source of significant debate between the experts in such matters. In this paper, we present a case study and illustrate how issues such as interpretation of p -values and what "rejection of the null hypothesis" really "means" in such matters.     

Implementing reverse e-auctions: A learning process

Reverse e-auctions, which enable suppliers to compete on-line in real-time, are changing the way organizations select their suppliers. We explore how five large firms in different industries learned to use e-auctions, and how e-auctions were integrated into their purchasing processes. To successfully implement e-auctions, organizations should: (1) build e-auction competencies; (2) organize for knowledge management; (3) create a holistic sourcing process; (4) focus on the total cost of ownership; and (5) experiment with e-auction designs. Key observations are drawn from the case studies, and implications for supply managers are presented.     

PRINCIPAL AND AGENCY TRADES BY STOCKBROKERS ARE COMPLEMENTARY: THE WELFARE EFFECTS OF DEREGULATING AGENCY TRADING AND BANNING PRINCIPAL TRADES

This paper models the demand for stockbrokers' services in Australia, consisting of two related services, agency trades and principal trades. The relationship between agency and principal trades is estimated. The results indicate that the two services are complements rather than substitutes. Using unique accounting information, a model of agency and principal trading activities is estimated to determine the welfare effects of (i) deregulating brokerage commissions and (ii) a ban on principal trading by brokers. The results show a sizeable welfare gain to investors (amounting to about 60% of the gross revenue of brokers) stemming from deregulation of the minimum charge for agency trades. The loss in profitability by brokers due to deregulation is also computed and shown to be negligible. The results also show that due to complementarity, a ban on principal trading, even with deregulation of agency trading, can impose an arbitrarily high cost on investors which could, in principle, offset the gains from agency deregulation.

Expenditure patterns on food and non food items of Khayelitsha households,Western Cape,South Africa

Food insecurity or lack of access to adequate and nutritious food is a major determinant of under‐nutrition. Expenditure patterns accompanied by unemployment, low level of education, inflation and high food prices have a direct negative impact on food availability within households (Moller, 1997). Ghany and Schwenk (1993) found that as household income increases, the proportion of expenditures on food decreases, the proportion of expenditures on clothing, rent, fuel, and light stayed the same and that of sundries increased. The aim of this study was to investigate household expenditure patterns on food and non‐food items in Khayelitsha. A total of 20 households (10 from the formal and 10 from the informal settlements) were randomly selected from those willing to participate in the study. A questionnaire with open ended and closed questions was used to collect data. The questionnaire comprised four sections namely: biographical information, socio‐economic information which used wealth quintiles to assess households’ social economic status, total expenditure information and a food/hunger scale was used to assess households’ food availability. The findings revealed that households from informal settlements spent more money (62.2%) as a proportion of their income on food compared to households from the formal settlement (39%). There was higher unemployment rate (100%) at the informal settlement compared to the formal settlement (40%). Wealth quintiles scales did not reflect the social status of the households as equipment and assets owned by households were only used as fallback position during times of economic hardships. Households used different purchasing strategies; food and non‐food items were mainly purchased from outside the township (60%). Forty percent of the households bought their items from local shops and spazas because they allowed them to buy items whenever little money was available or to take items on credit. All the respondents preferred to buy bread and small items from spazas and local shops. Prices of items in the spazas and local shops were higher compared to prices of items in bigger shops outside the townships. The food/hunger scale and wealth quintiles showed that informal settlement households were more food insecure (as they were all unemployed and about 50% of the households ran out of food always) and had fewer assets compared to the formal settlement households. The implications of these findings underscore the need to improve socio‐economic conditions of low resource households through empowerment programs. These programs can be in the form of training in management/decision making, work related skills/literacy (to help them access formal employment), business management/income generation skills (to help them to be self‐employed), budgeting, and food gardening. This approach can help to increase the resource base and alleviate food insecurity in low resource households.     

The Economic Forces Driving Food Safety Quality in Meat and Poultry

This article examines the impact of regulation and market-driven private actions on food safety performance in the meat and poultry industries. We find that private actions account for about 80% and regulation about 20% of the overall reduction in the share of samples of cattle and hog carcasses, ground beef, and broilers testing positive for Salmonella if all regulation and private actions were increased by identical amounts.
