Random walk and efficiency tests in the Asia-Pacific foreign exchange markets: Evidence from the post-Asian currency crisis data 总被引:1,自引:0,他引:1
This paper empirically tests the random walk and efficiency hypothesis for 12 Asia-Pacific foreign exchange markets. The hypothesis is tested using individual as well as panel unit root tests and two variance-ratio tests. The study covers the high (daily) and medium (weekly) frequency post-Asian crisis spot exchange rate data from January 1998 to July 2007. The inferential outcomes do not differ substantially between the unit root tests and the variance-ratio tests when using daily data but differ significantly when using weekly data. With the daily data, both types of unit root tests identify unit root components for all the series and two variance-ratio tests provide the evidence of martingale behavior for majority of the exchange rates tested. With the weekly data, panel unit root tests identify unit root component for the exchange rates and, the unit root tests on a single series basis identify unit root component for 10 foreign exchange markets. However, the variance-ratio tests reject the martingale null for the majority of the exchange rates when using weekly data. 相似文献

Banking efficiency in transition economies 总被引:10,自引:0,他引:10
Laurent Weill 《Economics of Transition》2003,11(3):569-592
An increasing share of the banking sector is controlled by foreign capital in the majority of transition countries. To analyse the effects of this trend on the performance of the banking sector in these countries, this study conducts a comparative analysis of the performance of foreign‐owned and domestic‐owned banks operating in the Czech Republic and Poland. We use the stochastic frontier approach to compute cost efficiency scores. Following Mester (1996 ), financial capital is included in the cost frontier model to control for risk preferences. Our finding is that on average foreign‐owned banks are more efficient than domestic‐owned banks. We conclude, however, that this advantage does not result from differences in the scale of operations or the structure of activities. 相似文献

In 1992 a blue‐ribbon group of US economists led by Michael Porter concluded that the US stock market‐based corporate model was misallocating resources and jeopardising US competitiveness. The faster growth of US economy since then and the supposed US lead in the spread of information technology has brought new legitimacy to the stock market and the corporate model, which is being hailed as the universal standard. Two main conclusions of the analysis presented here are: (a) there is no warrant for revising the blue‐ribbon group’s conclusion; and (b) even US corporations let alone developing country ones would be better off not having stock market valuation as a corporate goal. 相似文献

作为不同的制度安排,除暂时存在的转轨经济模式外,其余英美、德日及家族治理三种模式均具有一定的有效性。随着经济的发展、时代的变迁及国际化潮流的兴起,各种模式不可避免地面临挑战,均需进行不断变革和调整,在相互学习和借鉴中,逐步渗透和融合。而中国上市公司在借鉴各模式有效性基础上,应选择适合中国国情的市场与组织并重、内外结合的治理模式。 相似文献

Does World Bank lending promote deregulation with stronger incentives and critical resources or slow the process by blunting the impact of crises and indirectly promoting state control? This paper analyzes empirical links between aid flows and regulatory burden. Econometric estimates based on panel data for 83 aid receiving countries over 5 year periods from 1970 to 2000 find that World Bank lending, while not specifically targeting high or low regulatory states, is linked to lower subsequent regulation. This link holds for multilateral donors more broadly while bilateral donor funds apparently fail to influence the level of regulation. 相似文献

Current methods for assessing capacity and its utilisation infisheries operate at the firm-level, but neglect industry capacity.Here, we introduce the Johansen-Färe measure of plant capacityof the firm into a multi-output, frontier-based version of theshort-run Johansen industry model. The model determines firmcapacity utilisation such that current industry outputs aremaintained, while minimising the use of fixed inputs at industrylevel and assuming abundant variable inputs. Policy extensionsrelevant to combating overfishing include tightening quotas,seasonal closures, linking economic and plant capacity, decommissioningschemes and area closures, implementation issues and equityconsiderations. The application to the Danish fisheries revealssubstantial overcapacity in the Danish fleet. 相似文献

In this paper, we shed light on short‐horizon return reversals. We show theoretically that a risk‐based rationale for reversals implies a relation between returns and past order flow, whereas a reversion in beliefs of biased agents does not do so. The empirical results indicate that returns are more strongly related to own‐return lags than to lagged order imbalances. Thus, the evidence suggests that monthly reversals are not completely captured by inventory effects and may be driven, in part, by belief reversion. We do find that returns are cross‐sectionally related to lagged imbalance innovations at horizons longer than a month. 相似文献
