This paper presents tests for the null hypothesis of no regime switching in Hamilton’s (Econometrica 57:357–384, 1989) regime
switching model. The test procedures exploit similarities between regime switching models, autoregressions with measurement
errors, and finite mixture models. The proposed tests are computationally simple and, contrary to likelihood based tests,
have a standard distribution under the null. When the methodology is applied to US GDP growth rates, no strong evidence of
regime switching is found.

在经济全球化的背景下,金融资本的国际化流动不断加强,促成了国际金融市场的联动性和互相影响程度不断加强.而金融市场的迅速发展和资产证券化程度的提高,使得金融对于经济的渗透程度和影响程度加大.伴随着经济周期的扩张和收缩,相应资产价格的泡沫的形成和破灭的过程也对经济产生巨大的影响,政府在这样的不同周期阶段的政策选择对于平滑经济和金融市场风险显得十分重要.文章作者试图探讨政府在泡沫形成期和泡沫破灭期的理性政策选择. 相似文献

一般来说,利率在国家间的传导主要有两条渠道:国际贸易间的传导和资本自由流动下的利率平价机制。本文采取分阶段考察,通过建立计量经济学模型,利用单位根检验和协整分析加以验证,发现在资本项目部分开放后,中美利率开始具有联动效应,作用方式又具有自身的特点。目前资本项目开放度不够高是阻碍我国同世界利率联动的主要原因。 相似文献

Spatiotemporal Modeling of Asian Citrus Canker Risks: Implications for Insurance and Indemnification Fund Models 总被引:1,自引:0,他引:1
Barry K. Goodwin Nicholas E. Piggott 《American journal of agricultural economics》2009,91(4):1038-1055
Asiatic citrus canker is a disease that poses a significant hazard to commercial citrus production. This article examines spatiotemporal models of the risks of citrus canker transmission. Models evaluate risks and are used to price annual contracts, which would pay producers a prespecified indemnity in the event that their grove is found to be infected with canker. Implications for risk management policy are discussed. 相似文献

In this study, we estimate Bayesian vector autoregression (BVAR) and time-varying structural VAR (TVP-VAR) models for Brazil, Indonesia, Mexico and Turkey to analyze the impacts of short-term interest rates on stock prices and exchange rates considering the relationships between these variables. BVAR and TVP-VAR models’ estimations indicate that monetary policy decisions of these countries lead to capital movements as well as capital movements may create a considerable amount of variation in exchange and stock markets both in the periods of economic stability and financial crisis. We also reveal that increases in interest rates intending to prevent capital outflows may lead to decrease in stock returns, which in turn may deteriorate the real economic activity in Indonesia, while changes in short-term interest rates in Brazil, Indonesia and Turkey cannot be used as a tool to stabilize the value of their home currencies against the USD. Our study highlights the importance of formulating an optimal monetary policy framework accompanied by macro-prudential polices, which help to reach inflation target and smooth the possible variations in exchange rates and stock prices during economic crisis conditions in Brazil, Indonesia, Mexico and Turkey. 相似文献

Abstract As we survey the literature of macroeconomic news in the foreign exchange market, we can by now look back on nearly 30 years of research. The first studies which analysed news effects on exchange rates were established in the early 1990s (see, for example, Dornbusch). Almost at the same time Meese and Rogoff published their influential paper, revealing the forecasting inferiority in exchange rates of structural models against the random walk. This finding has shocked the pillars of exchange rate economics and thus cast general suspicion on research focusing on fundamentals in this field. The eventual rising popularity of event studies can partly be attributed to the re‐establishment of the raison d’être of exchange rate economics. This work focuses on systematically surveying this literature with particular respect to its primary goal, i.e. shedding light on the analytical value of fundamental research. Thus, its major findings are, first, fundamental news does matter, whereas non‐fundamental news matters to a lesser degree. Second, news influences exchange rates via two separated channels, i.e. incorporating common information into prices directly or indirectly based upon order flow. Third, with a few exceptions the impact of fundamental news on exchange rates is fairly stable over time. 相似文献

In this paper, we study how central bank transparency influences the formation of money market expectations in emerging markets. The sample covers 25 countries for the period from January 1998 to December 2009. We find, first, that transparency reduces the bias (the difference between the money market rate and the weighted expected target rate over the contract period) in money market expectations. The effect is larger for countries with no exchange rate peg and countries with low income. Second, an intermediate level of transparency is found to have the most favorable influence on money market expectations: neither complete secrecy nor complete transparency is optimal. Finally, all subcategories of the Eijffinger and Geraats (2006) index lead to a smaller bias in expectations, with political transparency having the largest effect. 相似文献

This paper aims at explaining why the CFA countries have successfully maintained a currency union for several decades, despite failing to meet many of optimum currency area criteria. We suggest that the CFA zone, while not optimal, has been at least sustainable. We test this sustainability hypothesis by relying on the Behavioral Equilibrium Exchange Rate (BEER) approach. In particular, we assess and compare the convergence process of real exchange rates towards equilibrium for the CFA zone countries and a sample of other sub-Saharan African (SSA) countries. Our findings evidence that internal and external balances have been fostered and adjustments facilitated in the CFA zone as a whole—compared to other SSA countries—as well as in each of its member countries. 相似文献

This paper analyzes the main characteristics of travel behavior by the Arab minority community in Israel and discusses two issues related to household travel surveys: data collection among minorities and under-reporting of mid-day trips.Household travel surveys are generally designed and conducted for the majority population and, therefore, lack a proper accounting of minorities and miss many of their less-frequent trips. An alternative approach to conducting household surveys is presented, with the aim of improving data quality for transportation planning. The survey was designed for and conducted in three Arab towns in Israel. The main improvement of the survey involves better interaction between interviewer and interviewee, which should materialize into a relaxed environment that allows for obtaining detailed, reliable results within a reasonable amount of time.The results of the survey employing the alternative approach were compared to a sub-sample of the same towns taken from a regional survey conducted by the regional planning agency at the same time. The paper presents simple statistics on the main variables for each survey. Significant differences are found in the two data sets, mostly regarding the frequency of less frequent, non-home-based trips. A plausible explanation for these differences relates to the more detailed and improved data collected in the new survey. 相似文献
