We investigate bank stocks'sensitivity to changes in interest rates and the factors affecting this sensitivity. We focus on whether the exposure of commercial banks to interest rate risk is conditioned on certain balance sheet and income statement ratios. We find a significantly negative relation between bank stock returns and changes in interest rates over the period 1991–1996. We also find that bank characteristics measured from basic financial statement information explain bank stocks'sensitivity to interest rate changes. These results suggest that bank managers, analysts, and regulators can use this information to assess the relative risk exposure of banks.  相似文献

Summary The old growth theory of the 1950s led to certain conclusions about the sorts of economic policies that would promote economic growth, and also about their limitations. The new growth theory of the 1980s makes much stronger assumptions and leads to correspondingly stronger conclusions about the scope of growth-promoting policy. This article argues that: (1) empirical work so far has neither confirmed nor denied the strong assumptions underlying the new theory; (2) the theory is worth pursuing because of its intrinsic interest and the possibilities it opens up; (3) whatever the final verdict on the new theory, both theory and evidence support the belief that significant long-run gains, even if not permanent changes in the growth rate, can be achieved by increased investment in the broadest sense, including human capital, technological knowledge, and industrial plant and equipment.Fifth Tinbergen Lecture delivered on October 4, 1991, in Amersfoort for the Royal Netherlands Economic Association  相似文献

This paper discusses the impact of a redistribution of current income from the White to the Black population on the distribution of sectoral output, and total employment by means of a semi‐closed input‐output model.

The results show that a redistribution of current income towards Black households — which no doubt will have positive social and political repercussions — has a non‐negative effect on GDP and a definite positive effect on the performance of sectors with a high private consumption expenditure component, as well as on total employment.  相似文献

Different viewpoints were expressed at the 1990 annual national conference of the South African Society for Agricultural Extension regarding the role of extension in the development of the farmer as entrepreneur. It is expected that public funding will increasingly be limited to functions of general public interest. To achieve independence farmers should be willing to expose themselves to entrepreneur development stimuli. it is in the public interest to develop scarce human, economic and natural resources. Research findings indicate distinct behavioral differences between entrepreneurs of differing perceptions. A comprehensive interdisciplinary education is recommended for agriculturalists. Because needs change, education programmes must be re‐evaluated from time to time. It serves little purpose to educate people in extension who do not have a technical message to communicate. The state extension service seeks closer cooperation and liaison with agricultural co‐operative and private sector know‐how. Departmental policy will probably be less rigid in future.

A clear distinction should be made between information and extension services. The adoption of an ethical code for extensionists may be opportune. Relevancy is an important contributing factor to extensionist credibility.  相似文献

System operators in the electricity industry purchase reserve capacity in a procurement auction in which suppliers offer two-part bids, one part for making capacity available and another part for supplying incremental energy when called. Key ingredients of an efficient auction design are the scoring rule for comparing bids, and the settlement rule for paying accepted bids. We use the principle of incentive compatibility to establish that very simple rules suffice. In particular, the scoring rule uses only the capacity part of the bid, and energy supplies are paid the spot price. This is the design adopted in California.  相似文献

This article presents an assessment of recent tourism performance in the countries of the Southern African Development Community region, as well as an evaluation of future prospects. It examines growth rates and source markets in developing a profile of current tourism to the region. It identifies and assesses the current and probable future impact of a range of issues and problems, which are serving either to help or hinder tourism development. It suggests necessary actions for facilitating the accelerated development of tourism. The article also analyses the countries' tourism development policies and their competitive standing with other parts of Africa and other world regions from the market's viewpoint. It evaluates future growth prospects for the region by relating these various strands of analysis to the assessments made in the World Tourism Organization's Tourism 2020 vision study. The conclusion is one of qualified optimism: the natural and sociocultural resources of the region match the growing tastes of the international tourism market but, without concerted action to improve international access and tackle the major (real and imagined) threats to tourist safety prevailing in the region, growth rates will continue to be below their potential. The region's physical remoteness from the military theatre of action consequent to the 11 September 2001 terrorist attacks in the United States could well bring the countries of the SADC, and especially South Africa, some benefit from being perceived in tourist-generating markets as safe from these activities.  相似文献

Previous research has suggested that the smallest firms are those most vulnerable to international competition, as measured by exchange rate fluctuations and import shares. However, that work—and the overwhelming bulk of the empirical literature on determinants of exit or firm survival—dealt entirely with the manufacturing sector of the economy. This paper analyzes annual US data for 1989–2005 for about 50 wholesale and retail sectors to explain small firm exit rates in several employment size categories. The main result is that wholesalers respond negatively to a stronger currency in a manner similar to that of manufacturers, while retailers are generally unaffected.  相似文献

This article explores the change in the level of competition in rural banking markets after the deregulation that occurred following passage of the Riegle‐Neal Act of 1994. Using an empirical model that utilizes both the number of banks and the value of deposits in a cross‐section of 278 rural markets, we decompose the impact of the entry of new banks into resulting changes in per capita demand and the costs/profits of local banks in 1994 and 2004. The results support the view that local banking markets have become more competitive since the mid‐1990s.  相似文献
