Can Britain benefit from immigration from Hong Kong? William McGurn and Julian Simon, drawing on experience from America, argue that Britain has much to gain from migrants from Hong Kong. 相似文献

We present an economically motivated two–factor term structure model that generalizes existing stochastic mean term structure models. By allowing a certain parameter to acquire dynamical behavior we extend the two–factor model to obtain a nonlinear three–factor model that is shown, in a deterministic version, to be equivalent to the Lorenz system of differential equations. With reasonable parameter values the model exhibits chaotic behavior. It successfully emulates certain properties of interest rates including cyclical behavior on a business cycle time scale. Estimation and pricing issues are discussed. Standard PCA techniques used to estimate HJM type models are observed to be equivalent to dimensional estimates commonly applied to 'spatial data' in nonlinear systems analysis.
It is concluded that techniques commonly used in the analysis of nonlinear systems may be directly applicable to interest rate models, offering new insights in the development of these models. Tests of nonlinearity in interest rate behavior may need to focus on long cycle times. 相似文献

The ownership of German corporations is quite different today from that of Anglo-American firms. How did this come about? To what extent is it attributable to regulation? A specially constructed data set on financing and ownership of German corporations from the end of the 19th century to the middle of the 20th century reveals that, as in the UK, there was a high degree of activity on German stock markets with firms issuing equity in preference to borrowing from banks, and insider and family ownership declining rapidly. However, unlike in the UK, other companies and banks emerged as the main holders of equity, with banks holding shares primarily as custodians of other investors rather than on their own account. The changing pattern of ownership concentration was therefore very different from that of the UK with regulation reinforcing the control that banks exercised on behalf of other investors. 相似文献

The mechanism by which governments sell debt at auction imposes unnecessary risks on primary dealers, who charge for these risks by bidding less. A better auction mechanism would increase the price at which governments sell their debt. Further, selling a specially designed futures contract would reduce dealers'balance sheet usage, again increasing revenue, and would also permit the authorities to match cash inflows with cash outflows. 相似文献

This article provides an overview of mandated commodity programs in California, and summarizes and interprets existing evidence on their economic impacts. The analysis draws upon the recent book edited by the authors: The Economics of Commodity Promotion Programs: Lessons from California . New York: Peter Lang Publishing, April 2005. The book documents the institutional arrangements, summarizes the history of recent litigation, and presents the results of a number of benefit–cost studies of mandated commodity programs in California. The overwhelming conclusion from the studies reported in the article is that the programs have been very profitable for California's agricultural producers. 相似文献

Annual data for forty-eight states are used to account for changes in the composition of input and output aggregates over space and time, and thereby to obtain new evidence on changes in inputs, outputs, and productivity in U.S. agriculture. The measures change significantly when we use state-specific rather than national prices and when we allow for changes in the composition of the aggregates, especially of labor and capital inputs. We compare our estimates and those reported by Ball et al. ( American Journal of Agricultural Economics 81(1999):164–79). The national estimates are similar but substantial differences are found in state-level productivity growth. 相似文献

An equilibrium displacement model of the world wool top industry is used to estimate the returns to the Australian wool industry from productivity improvements in farm production, in top making and in textile manufacturing. The returns to the industry from these different types of research and development are sensitive to the extent of substitution possibilities between Australian wool and other inputs used by the wool processing and textile industries but it appears that research resources have to be much more efficient in off-farm activities for the Australian wool industry to receive benefits similar to those from farm research activities. 相似文献

With the new German Gene Diagnostic Act (Gendiagnostikgesetz) the legislator aims at improving the protection of insurance applicants by prohibiting private insurers from collecting and using genetic information. However, the analysis of the new provisions shows that the provisions pertaining to insurance neither provide a comprehensive protection against genetic discrimination of insurance applicants and insured nor do they protect their right of gene-informational self-determination. Cuts of insurance benefits of the insured in private health insurance as well as incoherent disclosure obligations for insurance applicants unconstitutionally limit the rights of affected people as compared to the time before the Gene Diagnostic Act came into force. In summary, the new Gene Diagnostic Act does not only fail to meet its claims and thus falls short of the expectations, but also, due to numerous unclear provisions, poses a series of grave problems for insurance applicants, privately insured and private insurers. 相似文献

This paper examines the impact of temporal variation in labour market institutions and other structural factors on unemployment in Europe. A system comprising a labour demand and a wage equation is estimated on pooled time‐series data for the six largest EU countries for the 1980s and 1990s. The results suggest that changes in regional mismatch, trade union density and the ratio between consumer and producer prices are positively associated with structural unemployment. This result is robust to a wide variety of different specifications. No consistent role is found for other institutional factors (such as social security benefits, employment security and minimum wage). 相似文献
