The UK received its first sovereign credit ratings in 1978. Despite having required financial assistance from the International Monetary Fund only 18 months earlier, the British government managed to secure ‘triple‐A’ ratings from both Standard and Poor's and Moody's. Both assessments of creditworthiness reflected improving economic conditions but also British efforts to influence the sovereign ratings process. The Bank of England and the Treasury sought guidance from American investment banks to prepare for the ratings process and then controlled the flow of information available to the rating agencies accordingly, stressing the strengths of the national economy and downplaying the weaknesses. The British government subsequently launched its first bond issue in the New York market to high levels of investor demand. Consideration of these achievements complements the historiography concerning Britain's economic fortunes in the late 1970s. Scrutiny of events also offers a rare glimpse into the confidential sovereign ratings process. Both agencies relied on a combination of quantitative and qualitative evaluations of the UK. In addition, this article highlights the existence of a unique period in the history of sovereign credit ratings. From 1974 to 1985, the ratings industry enjoyed a cautious revival focused principally on ‘triple‐A’ borrowers.  相似文献

We consider the optimal investment problem with random endowment in the presence of defaults. For an investor with constant absolute risk aversion, we identify the certainty equivalent, and compute prices for defaultable bonds and dynamic protection against default. This latter price is interpreted as the premium for a contingent credit default swap, and connects our work with earlier articles, where the investor is protected upon default. We consider a multiple risky asset model with a single default time, at which point each of the assets may jump in price. Investment opportunities are driven by a diffusion X taking values in an arbitrary region . We allow for stochastic volatility, correlation, and recovery; unbounded random endowments; and postdefault trading. We identify the certainty equivalent with a semilinear parabolic partial differential equation with quadratic growth in both function and gradient. Under minimal integrability assumptions, we show that the certainty equivalent is a classical solution. Numerical examples highlight the relationship between the factor process, market dynamics, utility‐based prices, and default insurance premium. In particular, we show that the holder of a defaultable bond has a strong incentive to short the underlying stock, even for very low default intensities.  相似文献

We analyze the effects of taxation in two-sided matching markets where agents have heterogeneous preferences over potential partners. Our model provides a continuous link between models of matching with and without transfers. Taxes generate inefficiency on the allocative margin, by changing who matches with whom. This allocative inefficiency can be nonmonotonic, but is weakly increasing in the tax rate under linear taxation if each worker has negative nonpecuniary utility of working. We adapt existing econometric methods for markets without taxes to our setting, and estimate preferences in the college-coach football market. We show through simulations that standard methods inaccurately measure deadweight loss.  相似文献

Approximations to utility indifference prices are provided for a contingent claim in the large position size limit. Results are valid for general utility functions on the real line and semi‐martingale models. It is shown that as the position size approaches infinity, the utility function's decay rate for large negative wealths is the primary driver of prices. For utilities with exponential decay, one may price like an exponential investor. For utilities with a power decay, one may price like a power investor after a suitable adjustment to the rate at which the position size becomes large. In a sizable class of diffusion models, limiting indifference prices are explicitly computed for an exponential investor. Furthermore, the large claim limit arises endogenously as the hedging error for the claim vanishes.  相似文献

This study examines the impact of across domain social support, work-family conflict (WFC) and job satisfaction, and explores the influence of family role allocations among these relationships. Family roles include breadwinner and caregiver. Direct effects were found for two types of support and both WFC and job satisfaction. Additionally, results provided some evidence that family roles moderated the support-outcome relationship, particularly for caregivers. The research and practical implications, as well as limitations of this study are discussed.  相似文献

To better understand potential reasons for a North American decline in fresh potato consumption, a region-wide survey (n = 1009) was undertaken in eastern Canada. Results were examined comparing high- and low-frequency potato users on a variety of factors, including beliefs, attitudes, barriers, needs, and satisfaction with potatoes. Respondents indicated positive perceptions pertaining to potato nutrition, taste, preparation, and overall enjoyment. Multiple logistic regression analysis suggested two variables—age and the perceived importance of potatoes for the everyday meal—were strong predictors of high versus low frequency of potato consumption. Respondents judged the ability to see the potato in the package, potato firmness, and locally produced as point-of-purchase characteristics particularly important when buying fresh potatoes. However, respondents also indicated that their needs were not fully met and expressed relatively low levels of satisfaction when purchasing potatoes. Based on the results, suggestions are provided for improving the marketing of fresh potatoes.  相似文献
