Recent studies of the experience of the British life insurance industry indicate that a period of transition, and the development of more diversified investment strategies, began in the interwar period. Australian life insurers lagged behind their British counterparts in the introduction of such strategies. This paper investigates why this was the case. It argues that in the Australian market there was both a lack of opportunity and incentive to broaden asset portfolios. However, this did not mean that asset management practices did not advance. Australian life offices became progressively more sophisticated in their approach to portfolio management during this period. Developments in the interwar period provided a grounding for post-war expansion into the equity market.  相似文献

This article discusses entrepreneurship in a depleted community in transition. The purpose is to develop knowledge about how discourses are used in the positioning of identity in regional development. The concept positioning illustrates how identities are provoked, challenged, negotiated and moved into identity positions that break away from the idea of imitating successful and wealthy regions; instead, locality, place and history emerge as important resources from where local actors obtain agency and recognize new opportunities. Ethnographic data of a single case were collected over a six-year period between 2005 and 2010. The longitudinal nature of the study made it possible to incorporate how local stakeholders took on new identity positions, while handling their inspiration as well as their frustration. Results show how rural change was conditioned by discourses and how entrepreneurship challenged and reframed dominating structures through interaction between entrepreneurship and community. Four discourses, expressed as dichotomies available to people in this depleted community, illustrate the interactive process of positioning: change vs. traditions, rational vs. irrational, spectacular vs. mundane and individual vs. collective. The results support research emphasizing perspectives that acknowledge interaction between entrepreneurship and context as well as discursive aspects of regional development.  相似文献

This paper proposes a Bayesian, graph‐based approach to identification in vector autoregressive (VAR) models. In our Bayesian graphical VAR (BGVAR) model, the contemporaneous and temporal causal structures of the structural VAR model are represented by two different graphs. We also provide an efficient Markov chain Monte Carlo algorithm to estimate jointly the two causal structures and the parameters of the reduced‐form VAR model. The BGVAR approach is shown to be quite effective in dealing with model identification and selection in multivariate time series of moderate dimension, as those considered in the economic literature. In the macroeconomic application the BGVAR identifies the relevant structural relationships among 20 US economic variables, thus providing a useful tool for policy analysis. The financial application contributes to the recent econometric literature on financial interconnectedness. The BGVAR approach provides evidence of a strong unidirectional linkage from financial to non‐financial super‐sectors during the 2007–2009 financial crisis and a strong bidirectional linkage between the two sectors during the 2010–2013 European sovereign debt crisis.

We estimate parametric and semi‐parametric binary choice models of benefit take‐up by British pensioners and use a revealed preference argument to infer the cash‐equivalent value of disutility arising from stigma or complexity of the claims process. These implicit costs turn out to be relatively small, averaging about £3–4 per week across Income Support recipients. Using the Foster–Greer–Thorbecke measure of poverty among pensioners, we find that allowing for implicit claim costs incurred by benefit recipients raises the measured degree of poverty by not more than 13%.

Occupied bed days are often used as a demand indicator when calculating the number of nurses required to provide safe care. However, such calculations fail to take into account the amount of nursing time consumed by the "unoccupied bed." This study used direct observation time-and-motion methods to estimate the time and costs associated with a bed that is unoccupied. The average time taken to complete all of the activities associated with a bed that was unoccupied due to an internal transfer was 8.65 minutes, for a patient discharge 26.27 minutes, and for a patient admission 37.7 minutes. An average daily cost for activities surrounding these patient movements was approximately $386/day (AUD) in registered/enrolled nursing salaries alone. The unoccupied bed is not resource neutral and time associated with its maintenance should be considered when calculating nursing requirements to provide safe care.  相似文献

The life insurance industry in Australia has traditionally been an important source of long term finance for both the public and private sector. However, very little historical analysis has been undertaken into an industry that constitutes a fundamental part of the economy's financial sector. The present climate of deregulation has initiated an irrevocable process of change within the industry. To comprehend the full implications of this change it is necessary to have an understanding of how the industry has evolved. This paper seeks to provide a background account of the growth of the life insurance industry in Australia highlighting the influences that have determined the structure of the industry.  相似文献

In the wake of the deregulation of the financial sector in Australia in the 1980s and 1990s the life insurance industry has undergone a period of rapid change and reorganisation. Part of this adjustment has been the move towards the integration of financial service provision and the rise of bancassurance. This paper investigates the strategies adopted by Australian life insurers as they moved into the increasingly competitive environment triggered by the lifting of government restrictions on banking practices. It compares the approach of life insurers with that adopted in an earlier period of expansion and change. During the 1950s and 1960s an influx of foreign owned insurance companies into the Australian market precipitated the diversification of domestic life insurers into other insurance markets. The catalyst for change in both cases was the change in information costs brought about by the change in the competitive environment. The experience of the Australian life insurance market would suggest that there is a link between changing information costs and changing organisational structures. However this link is circumscribed by the institutional environment.  相似文献

This article uses nationally representative data from Malawi's 2004/05 Integrated Household Survey (IHS2) to examine whether rainfall conditions influence a rural worker's decision to make a long‐term move to an urban or another rural area. Results of a Full Information Maximum Likelihood regression model reveal that (1) rainfall shocks have a negative association with rural out‐migration, (2) migrants choose to move to communities where rainfall variability and drought probability are lower, and (3) rainfall shocks have larger negative effects on the consumption of recent migrants than on the consumption of long‐time residents.  相似文献

The Sony PlayStation 3 (PS3) offers the computational power of a parallel processor at low cost, which makes it a great starter unit for development in parallel programming. To explore the capabilities of the unit, we took a simple ray tracing program and extended it to render triangulated height field data across the PS3’s 6 synergistic processing units (SPUs). We also implemented the heat averaging equation as a precursor to CFD analysis on the PS3. In our studies, we found the Cell engine in the PS3 to be a powerful machine, however great care must be taken while developing because its unique platform calls for many levels of optimization to ensure efficiency.  相似文献
