The Role of Hospital and Market Characteristics in Invasive Cardiac Service Diffusion

Little is known about how the adoption and diffusion of medical innovation is related to and influenced by market characteristics such as competition. The particular complications that are involved in investigating these relationships in the health care sector may explain the dearth of research. We examine three invasive cardiac services: diagnostic angiography, percutaneous coronary interventions, and coronary artery bypass grafting. We document the relationship between the adoption by hospitals of these three invasive cardiac services and the characteristics of the hospitals, their markets, and the interactions among them, from 1997 to 2014. The results show that the probability of hospitals’ adopting a new cardiac service depends on competition in two distinct ways: (1) hospitals are substantially more likely to adopt an invasive cardiac service if competitor hospitals also adopt new services; and (2) hospitals are less likely to adopt a new service if a larger fraction of the nearby population already has geographic access to the service at a nearby hospital. The first effect is stronger, leading to the net effect that hospitals duplicate rather than expand access to care. In addition, for-profit hospitals are considerably more likely to adopt these cardiac services than are either nonprofit or government-owned hospitals. Nonprofit hospitals in high-penetration, for-profit markets are also more likely to adopt them relative to other nonprofits. These results suggest that factors other than medical need—such as a medical arms race—partially explain technological adoption.     

UK Housing Market: Time Series Processes with Independent and Identically Distributed Residuals

The paper examines whether a univariate data generating process can be identified which explains the data by having residuals that are independent and identically distributed, as verified by the BDS test. The stationary first differenced natural log quarterly house price index is regressed, initially with a constant variance and then with a conditional variance. The only regression function that produces independent and identically distributed standardised residuals is a mean process based on a pure random walk format with Exponential GARCH in mean for the conditional variance. There is an indication of an asymmetric volatility feedback effect but higher frequency data is required to confirm this. There could be scope for forecasting the index but this is tempered by the reduction in the power of the BDS test if there is a non-linear conditional variance process.     

TOWARDS A COMPARISON OF CHEMICAL-FREE AND CONVENTIONAL FARMING IN AUSTRALIA

The classes of benefits and costs, private and external, arising from a partial movement from conventional to chemical-free farming are considered, a report is provided on a comparison of physical and financial characteristics of chemical-free and conventional cereal/livestock farming in southeastern Australia, a key finding is that private net returns were similar for the two types of farmers, A favourable change in net externalities could be expected from a movement towards chemical-free farming, policy implications relating to the taxation of chemical use in agriculture, and to research, extension and marketing are discussed.     

PROTECTION STRATEGIES FOR AUSTRALIA

The Industries Assistance Commission and the Green Paper on Rural Policy support different protection strategies. Both strategies allow the achievement of a pattern of protection consistent with Pareto-efficiency. The Green Paper on Manufacturing proposed an approach to tariffs that would perpetuate inefficient resource allocation. The argument of the lAC and the Green Papers on protection policy is examined. A programme of across the board reductions in protection leading to free trade, modified for terms of trade effects, is suggested. It is also argued that initial increases in assistance for low cost industries are not inconsistent with such a programme.     

Women in industrial advertisements

This is one of the first studies to analyze the way in which women are portrayed in industrial advertising. It concludes that the use of sex is not a major selling strategy and that, with one exception, women's role in industrial life is accurately reflected.     

Protecting Employee Entitlements

Corporate failure exposes employees to the possible loss of sums due as deferred benefits such as arise from annual leave entitlements. Through such deferred benefits, employees are significant, often involuntary, providers of working capital to their employer. They are not necessarily adequately compensated for the risk involved, nor able to influence corporate governance in the ways available to other creditors. These issues have been largely neglected in the debate to date, and they provide the focus for an evaluation of alternative policies which have been proposed (or implemented) for protecting employee entitlements.     

On the Sale of Production Rights and Firm Organization

It is argued that the owner of production rights may not be indifferent across organizational structures of producers. In particular, the owner may prefer to grant some or all of the rights to labor-managed firms. The reason is that such firms adopt a less competitive strategy and so generate more industry rent, which the owner can capture as fee payments. A mixed duopoly may be particularly attractive. The conflict between revenue-raising and the pursuit of efficiency as objectives of government privatization programs is highlighted, and the relevance to East European reform discussed.     

THE BEHAVIOR OF CASINO GAMING REVENUE OVER THE BUSINESS CYCLE CONSIDERING ALTERNATIVE MEASURES OF “INCOME”

Reasons exist for believing that casino gaming revenue does not respond equally to all sources of income over the business cycle. We examine the growth and variability of casino revenue resulting from the growth and variability in different sources of income. We find that casino revenue behaves quite differently in response to short‐run and long‐run variation in each income source, thus revealing that the common use of personal income masks underlying drivers of each state's business cycle. Our results have implications for revenue forecasting models, research on the growth and variability of tax bases in general, and public policy. (JEL H72, H79, L83)
