Factors influencing adoption of conservation tillage in Australian cropping regions*

The purpose of this research is to improve understanding of conservation tillage adoption decisions by identifying key biophysical and socio‐economic factors influencing no‐till adoption by grain growers across four Australian cropping regions. The study is based on interviews with 384 grain growers using a questionnaire aimed at eliciting perceptions relating to a range of possible long‐ and short‐term agronomic interactions associated with the relative economic advantage of shifting to a no‐tillage cropping system. Together with other farm and farmer‐specific variables, a dichotomous logistic regression analysis was used to identify opportunities for research and extension to facilitate more rapid adoption decisions. The broader systems approach to considering conservation tillage adoption identified important determinants of adoption not associated with soil conservation and erosion prevention benefits. Most growers recognised the erosion‐reducing benefits of no‐till but it was not an important factor in explaining whether a grower was an adopter or non‐adopter. Perceptions associated with shorter‐term crop production benefits under no‐till, such as the relative effectiveness of pre‐emergent herbicides and the ability to sow crops earlier on less rainfall were influential. Employment of a consultant and increased attendance of cropping extension activities were strongly associated with no‐till adoption, confirming the information and learning‐intensive nature of adopting no‐till cropping systems.     

GOVERNMENT POLICY AND THE CHANGING MARKET IN RESIDENTIAL CARE FOR THE ELDERLY: A FINANCIAL ANALYSIS OF THE PRIVATE SECTOR

The market in residential care for the elderly is in a state of flux. Key factors are the increasing proportion of elderly (particularly the 85+ age group) and central governments new community care agenda. The mixed economy of public, private and voluntary residential provision will continue but community care policy changes will entail (a) the new role of case managers in the local authorities and (b) an anticipation that the private sector will play a more significant role than hitherto not only in meeting the demand for residential care but also in leading the way by diversifying into new types of care provision. These issues are addressed by (1) examining and commenting on government policy towards the care of the elderly and (2) examining, in detail, the profitability and financial viability of a random sample of private residential homes for the elderly. This financial analysis suggests that, at present, the ability of the private sector to innovate and expand into new forms of service provision is constrained by the number of homes which operate at the margins of viability. The implications of this are that (a) government policy may be founded on an optimistic view of the ability of private sector provision to respond as expected to the new community care agenda and (b) case managers in local authorities may have to exercise considerable financial expertise in identifying financial vulnerability, as well as social work skills, in the deployment of available funds for residential care for the elderly.     

Political risk and political loss for foreign investment

In 1986, The Economist produced a risk analysis for 50 countries under the title “Countries in Trouble.” The analysis resulted in a risk rating based on scores from ten weighted political and social variables. This article examines the theoretical structure underlying the analysis and assesses the accuracy of The Economist's projections. Discussion includes considerations of variable choice, variable weights, and data derivation as well as the impact on the outcomes of implicit theory. Conclusions focus on the possibility that underlying theory has predetermined some results, altering the direction of foreign investment. The discussion stresses the connection between abstract theory and profit/loss consequences for businesses in the field of political risk analysis and, particularly, the need for assessing and measuring politically determined losses in order to statistically evaluate the accuracy and utility of risk assessments.     

The cost-effectiveness of same-day admission surgery

The move toward outpatient and same-day surgical services has been phenomenal in recent years. In this study comparing same-day and traditional surgery patients in a Midwest tertiary care center, hospital charges and costs were significantly lower for same-day surgery patients. These differences reflected decreased lengths of stay and reduced ancillary services.     

An analysis of the causes of recent banking crises

The incidence of systemic banking crises has risen over the past twenty years and the costs have been high. Although each country's experience has country-specific factors, several common elements appear in most crisis countries: (1) volatility in the macro economy; (2) the inheritance of structural weaknesses in the economy and financial system; (3) hazardous banking practices; (4) hazardous incentive structures and moral hazard within the financial system; (5) ineffective regulation; (6) weak monitoring and supervision by official agencies; (7) the absence of effective market discipline on banks, and (8) structurally unsound corporate governance mechanisms within banks and their borrowing customers. Causes of such crises are complex and a myopic focus on single factors (e. g. instability in the macro economy, weak regulation, etc.) misses the essential feature of interrelated and multidimensional causal factors. Although macro-instability has been a common feature, and may often have been the proximate cause, banking crises usually emerge because instability in the economy reveals existing weaknesses within the banking system.
