Over recent years, a study on risk management has been prompted by the Basel committee for regular banking supervisory. There are however limitations of some widely-used risk management methods that either calculate risk measures under the Gaussian distributional assumption or involve numerical difficulty. The primary aim of this paper is to present a realistic and fast method, GHICA, which overcomes the limitations in multivariate risk analysis. The idea is to first retrieve independent components (ICs) out of the observed high-dimensional time series and then individually and adaptively fit the resulting ICs in the generalized hyperbolic (GH) distributional framework. For the volatility estimation of each IC, the local exponential smoothing technique is used to achieve the best possible accuracy of estimation. Finally, the fast Fourier transformation technique is used to approximate the density of the portfolio returns.The proposed GHICA method is applicable to covariance estimation as well. It is compared with the dynamic conditional correlation (DCC) method based on the simulated data with d = 50 GH distributed components. We further implement the GHICA method to calculate risk measures given 20-dimensional German DAX portfolios and a dynamic exchange rate portfolio. Several alternative methods are considered as well to compare the accuracy of calculation with the GHICA one. 相似文献

We demonstrate that auctioning market licenses may result in higher market prices than assigning them via more random allocation mechanisms. When future market profit is uncertain, winning an auction is like winning a lottery ticket. If firms differ in risk attitudes, auctions select the least risk-averse firm, which, in turn, set a higher price (or a higher quantity, in case quantity is the decision variable) in the marketplace than an average firm. 相似文献

Before an MNC even begins negotiation to set up a joint venture in the Soviet Union or otherwise do business there, it needs to understand the labyrinthine Soviet management system it will encounter. Here, Vladimir L. Kvint, a prominent Soviet professor and business authority now heading up his own consulting business in New York City, offers insights into the Soviet management system. 相似文献

This study investigates the implications of models of capitalism for the responsiveness of countries’ fiscal policies during business cycles using new data for member countries of the Organization for Economic Cooperation and Development and China. We expand the literature by adding the category of East Asian nonliberal capitalism to the established distinction of liberal market economies and nonliberal coordinated market economies. These three differ substantially not just in their fiscal policies, but also in monetary policies, degree of financial market orientation, exchange rate regime, and labor market organization. As in previous studies, we find that governments of liberal economies adopt more countercyclical fiscal policies. Departing from existing studies, however, among the nonliberal models of capitalism, (East Asian) state-led models have more countercyclical fiscal policies than (European) coordinated market economies, perhaps as countercyclical as liberal economies, both historically and during the 2007–9 crisis. This is due to less independent central banks, managed float of exchange rates, and limited financial market orientation and financial openness in East Asia, which allow for more active fiscal policy. Among political factors, left-of-center governments, fractionalized party systems, and election years are associated weakly with countercyclical fiscal policy, as expected. Labor market coordination and welfare generosity have unclear roles in regard to fiscal policy, a topic for future research. 相似文献

The "New" Political Economies (A View from Russia) 总被引:1,自引:0,他引:1
Vladimir Kollontai 《American journal of economics and sociology》2002,61(1):217-232
This paper analyses some of the problems created by a rapidly changing interaction between the political and the economic spheres in society. In periods of condensed social change this interaction is profoundly different from customary evolutionary developments. In Russia various political economic concepts during the last century have led to profound shifts in economic mechanisms and structures (first toward a planned economy, later toward a market one). A knowledge of this experience (and the new problems that surface) might be useful if globalisation, environmental issues and the transition to a post-industrial society should lead to periods of condensed socioeconomic change in the West. 相似文献

The purpose of this study is to examine the relationship between innovativeness, quality, growth, profitability, and market value at the firm level. Building on concepts from a resource‐based view of a firm and organizational learning, innovation and quality literature, we propose the innovativeness–quality–performance model, which describes how a firm's capability to balance innovativeness with quality drives growth and profitability, and in turn drives superior market value. Results of structural equation models indicate that (1) innovativeness mediates the relationship between quality and growth, (2) quality mediates the relationship between innovativeness and profitability, (3) both innovativeness and quality have mediation effects on market value, and (4) both growth and profitability have mediation effects on market value. Implications for theories and practices are discussed. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

This paper tests for the existence of short-run equilibrium in the urban housing market in Metropolitan Toronto. The alternative hypothesis is the housing market segmented with respect to locational and structural attributes. We found insignificant differences in attribute prices across hypothesized submarkets. This implies that an unstratified hedonic price regressions model, based on the assumption of short-run equilibrium, is equally efficient in the analysis of housing prices as a model based on a number of subsamples stratified along lines of segmentation. 相似文献
