In this article we examine which farmers would be early entrants into weather‐index insurance markets in Ethiopia, were such markets to develop on a large scale. We do this by examining the determinants of willingness to pay for weather insurance among 1,400 Ethiopian households that have been tracked for 15 years as part of the Ethiopian Rural household Survey. This provides both historical and current information with which to assess the determinants of demand. We find that educated, wealthier individuals are more likely to purchase insurance. Risk aversion is associated with low insurance take‐up suggesting that models of technology adoption can inform the purchase and spread of weather index insurance. We also assess how willingness to pay varied as two key characteristics of the contract were varied and found that basis risk reduces demand for insurance particularly when the price of the contract is high, and that provision of insurance through groups is preferred by female headed households and individuals with lower levels of education.  相似文献

The motivation for this study rests on two factors. First, Australian dairy farmers spend around $20 million annually on generic promotion and estimates of the returns from this expenditure are required to facilitate efficient investment decisions. Second, while the Australian dairy industry has been highly regulated, there has been a substantial reduction in assistance over the past decade and farm‐gate milk prices were deregulated on 1 July 2000. The profit potential of promotion may vary with the degree of regulation, so past estimates of the returns from promotion may not hold in the competitive environment of the future. Hence, the aim of this study is to examine the effects of government intervention on the profitability for dairy farmers of incremental changes in generic dairy promotion expenditure using a perfectly competitive market as a reference point. Competitive market price and quantity outcomes for the Australian dairy industry are estimated. The impacts of increments in dairy product and competing product generic promotion expenditures on dairy farmers’ profits are assessed using equilibrium displacement modelling. Finally, graphical procedures are used to examine the effects of dairy industry regulation on the profitability of dairy promotion.  相似文献

The Sydney housing market peaked in 2003. The period 2001–2006 is, therefore, of particular interest since it captures a boom and bust in the housing market. We compute hedonic, repeat-sales and median price indexes for five regions in Sydney over this period. While the three approaches are in broad agreement regarding the timing of the turning point in the housing market, some important differences also emerge. In particular, we find evidence of sample selection bias in our hedonic and repeat-sales data sets (with the former focusing more on better quality dwellings and the latter more on lower quality dwellings). These sample selection biases could in turn cause bias (in opposite directions) in our hedonic and repeat-sales indexes. Median indexes may likewise be biased as a result of an apparent decline in the average quality of dwellings sold in the latter part of the sample. We also find evidence of convergence in prices across regions during the boom and divergence in the subsequent bust.  相似文献

Estimates suggest that 10 000 farms in the UK offer bed and breakfast (B and B) serviced accommodation. A thorough review of the existing literature indicates over 50% of Devon and Cornwall's farmhouse B and B sector operate without participating in any form of quality assurance inspection scheme. This research executes a stratified postal survey to gain a comprehensive understanding of Devon's farmhouse B and B product, with particular interest in extracting providers' attitudes towards quality assurance inspection schemes. The very representative results suggest a divergence of attitudes towards the notion of quality inspections for all farmhouse B and B providers. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献

A number of recent papers examine the relationship between default risk and equity returns, and the results are mixed. These studies employ different measures of default risk and we find that correlations between eight diverse measures of default risk tend to be less than 50%. Nonetheless, we find that the relationship between stock returns and diverse measures of default risk tends to be consistent; default risk is a significant determinant of stock returns and this relationship is “hump backed”, as predicted by Garlappi and Yan (2011).  相似文献

This research takes a retrospective look at modern consumption opportunities of the U.S. poor from both sides of the marketing exchange relationship. The paper opens with a critical assessment of the consumer-behavior literature and its primary focus on middle-class Americans. The next section profiles the impoverished and their purchasing habits and closes with a summary of how both have changed over the last forty years. Then a theoretical account is presented using consumer literature from the same timeframe. The paper ends with a discussion of common business practices and moral dilemmas that have continued over these decades, along with an ethical paradigm involving distributive justice to guide future management tactics.  相似文献

This paper describes a research programme carried out on a newly created long-distance cycle route in northern England during 1996 and 1997. The survey sought to: profile users, monitor the overall number of users, describe their spatial and temporal distribution and quantify their economic impacts. This was achieved using a combination of automatic counters, field interview questionnaires, self-completion questionnaires and telephone interviews. The data showed that for 1996 between 12,000 and 15,000 people used the route spending between £1.07 and £1.85 million. Over half the service providers along the route were found to have benefited. In 1997 fewer people used the route, 11,000 cyclists, and the economic impacts have declined in proportion to the use levels. Causes of the reduction of user numbers are considered. The methodology applied is described, and associated issues are discussed. Conclusions are drawn concerning the performance of the route in terms of the cycle tourism niche market. The implications for other cycle routes with tourism potential are considered.  相似文献

This study examines the market value of REIT dividends conditional on transparency of operating structure and effectiveness of boards. Results suggest that total, mandatory and discretionary dividends are valued by the market. Consistent with agency cost theory, results provide some evidence that discretionary dividends paid by REITs with greater principal-agent conflicts have greater market value. Specific results suggest an increased value of excess dividends paid by firms with more complex organizational structures (UPREITs) and, to some degree, less independent boards. This evidence implies the equity market recognizes REITs’ substitution of discretionary dividends for stronger governance.  相似文献
