Two distinguished Morgan Stanley “alumni” discuss how their management of risk and uncertainty has not only preserved but increased the profitability of their businesses. In both cases—one involving a commodities trading operation and the other a long‐short hedge fund—the key has been to find cost‐effective ways to “cut off the left tails” of the distribution by avoiding naked long or short positions and creating option‐like payoffs with limited downside. In the case of the hedge fund, the combination of longs and shorts with the use of other risk‐reducing strategies has enabled the fund's managers to produce twice the market's returns with only half the volatility (and only one losing year) during the 18‐year life of the fund. In the case of the commodities trading operation, the strategy is described as combining ownership of physical assets with the use of option pricing models to create what amount to “long gamma positions in the asset” that “produce payoffs regardless of whether the asset goes up or down in value.”  相似文献

This paper uses detailed industry level time-series data for the UK regions which suggests that convergence (at least in terms of output-per-employee) was not occurring during the period 1968–92. Based on testing for unit roots, it is found that in a majority of industries and regions growth was divergent, and consequently there is little empirical support for the neoclassical 'long‐run catch up' model.  相似文献

We re-examine the utility premium of Friedman–Savage [Friedman, Milton and Savage, Leonard J., “The Utility Analysis of Choices Involving Risk.” Journal of Political Economy 56, 1948, pp. 279–304.]. This measure is useful in understanding risky choices. For instance its reaction to an increased wealth equates to a precautionary demand for saving. We also analyze its two components.  相似文献

This paper utilizes the concept of aggregative consistency defined in Rubinstein and Fishburn [1986], and the FASB's concept of representational faithfulness to evaluate foreign currency translation and accounting for changing prices as embodied in SFAS 70. The paper shows that SFAS 70 produces measurement errors and creates a foreign currency translation adjustment which does not reflect the effects of exchange rate changes. The conditions defined in the paper also facilitate an evaluation of the relative merits of restate/translate and translate/restate. Restate/translate can conceivably be used if there is no consolidation. In the more usual case where consolidation is required, translate/restate using the relevant shareholders' consumption index will yield aggregatively consistent values under fewer restrictive conditions.  相似文献

A number of financial variables have been shown to be effective in explaining the time-series of aggregate equity returns in both the UK and the US. These include, inter alia , the equity dividend yield, the spread between the yields on long and short government bonds, and the lagged equity return. Recently, however, the ratio between the long government bond yield and the equity dividend yield – the gilt-equity yield ratio – has emerged as a variable that has considerable explanatory power for UK equity returns. This paper compares the predictive ability of the gilt-equity yield ratio with these other variables for UK and US equity returns, providing evidence on both in-sample and out-of-sample performance. For UK monthly returns, it is shown that while the dividend yield has substantial in-sample explanatory power, this is not matched by out-of sample forecast accuracy. The gilt-equity yield ratio, in contrast, performs well both in-sample and out-of-sample. Although the predictability of US monthly equity returns is much lower than for the UK, a similar result emerges, with the gilt-equity yield ratio dominating the other variables in terms of both in-sample explanatory power and out-of-sample forecast performance. The gilt-equity yield ratio is also shown to have substantial predictive ability for long horizon returns.  相似文献

Institutional change in water rights in the nineteenth century Australian colony of Victoria raised institutional efficiency, which contributed to long‐run economic growth. High‐quality human capital and the extension of voting rights (franchise) were crucial for efficient institutional change in the water sector. Quality human capital (literacy) appeared to increase the rural population's awareness of the economic impact of the existing structure of water rights that may have constrained growth in the agricultural sector and reduced investment incentives. Extension of the franchise allowed the rural population to exert political pressure for enactment of change in water rights, which resulted in efficiency‐enhancing policies and efficient institutions. The findings show these two factors were more important than Victoria's British colonial heritage in determining whether growth‐enhancing institutional change took place.  相似文献

This study assesses the contribution of exporting activities to aggregate productivity growth in the UK for all market‐based sectors for the period 1996–2004, using a weighted FAME dataset. Based on decompositions of productivity growth, our findings suggest that, overall, exporting firms experience faster productivity growth than non‐exporting firms and therefore contribute more to national productivity growth. In addition, aggregate productivity for exporters benefits from a large contribution from ‘continuing’ firms improving their productivity, as well as exporters that have been taken‐over/merged or started‐up as new firms. In contrast, most of the TFP improvement for non‐exporters is attributable to lower productivity firms exiting, rather than from internal improvements or the productivity‐enhancing impact of new firms.  相似文献

This study set out to examine environmental factors impacting on the food literacy of adolescents. It utilized data from a nation‐wide survey of home economics teachers regarding their experience of food literacy education in Australian high schools. Content analysis and the ANGELO framework were applied to analyse free‐text comments from 78 of the respondents that were collected as part of a more extensive data set. The analysis of environmental factors revealed three enablers and ten barriers that could influence food literacy education delivered by high schools in Australia. High schools are well positioned to improve adolescents’ food literacy through a comprehensive, hands‐on approach in home economics. However, many environmental barriers were reported that could influence food literacy education in Australian high schools such as: lack of teaching materials and facilities, and human resources; the perceived inadequacy of the Australian school curriculum; non‐supportive school canteens; and negative role modelling. This study points to the need to eliminate or reduce these environmental barriers impacting on the capacity for effective food literacy education in high schools to help adolescents increase their food literacy and thereby support them in making informed food choices.  相似文献
