This article uses a microstructure approach to analyse the effectiveness of capital controls introduced in Brazil to counter an appreciation of the Real. Based on a rich data set from the Brazilian foreign exchange market, we estimate a reduced-form VAR to characterize the interaction of the central bank, financial and commercial customers in times of regulatory policy measures. We find that capital controls change market participants’ behaviour, and that central bank interventions elicit a significant response in financial order flow. Referring to the source of order flow, we find no direct price impact by financial flows and thus no evidence that the appreciation of the Real is driven by financial customers’ activity. Instead, commercial customers seem to be a primary driver of the Real within our model. 相似文献

在高职学生的发展过程中,信息交互是高职学生获取隐性信息的重要方法之一,可以提高学生的可持续发展能力。然而由于其自身的特殊性,隐性信息的获取是及其困难的。因此本文以计划行为理论为基础,以高职学生为研究对象,深入了解高职学生对待信息交互的态度,在此基础上,拟定问卷并进行调研,最后利用SPSS13.0对调研的数据进行信度和效度分析,从而得出影响高职学生信息交互行为的要素。 相似文献

Keynes, uncertainty and interest rates 总被引:1,自引:0,他引:1
Uncertainty plays an important role in The General Theory, particularlyin the theory of interest rates. Keynes did not provide a theoryof uncertainty, but he did make some enlightening remarks aboutthe direction he thought such a theory should take. I arguethat some modern innovations in the theory of probability allowus to build a theory which captures these Keynesian insights.If this is the right theory, however, uncertainty cannot carryits weight in Keynes's arguments. This does not mean that theconclusions of these arguments are necessarily mistaken; intheir best formulation they may succeed with merely an appealto risk. 相似文献

文章对20世纪90年代中东欧转轨国家汇率制度选择及其通胀绩效进行了实证考察。结果表明,这些国家在从计划经济向市场经济转轨的过程中,采取了几乎所有的汇率制度类型。对于转轨国家而言,汇率制度选择与通胀之间存在着非常密切的关系。在转轨的初期,通胀的压力和宏观经济的稳定性是政府主要考虑的因素,这些国家的政府都把稳定货币作为制定政策的出发点,汇率制度的选择也是围绕稳定货币进行的。这些国家的实践表明,钉住汇率制度反通胀的绩效要超过浮动汇率制度。 相似文献

This paper reviews and interprets some of the key policy implications that flow from a class of DSGE models for optimal monetary policy in the open economy. The framework suggests that good macroeconomic outcomes in open economies are possible by focusing inflation targeting that is implemented by a Taylor type rule, a rule that in equilibrium is reflected in the exchange rate as an asset price. Optimal monetary policy will not be able deliver a stationary (‘stable’) nominal exchange rate – let alone a fixed exchange rate or one that remains inside a target zone – because, absent a commitment device, optimal monetary can’t deliver a stationary domestic price level. Another feature in the data for inflation targeting countries that is consistent with monetary policy via Taylor type rule is that it will tend push the nominal exchange rate in the opposite direction from PPP in response to an ‘inflation’ shock—the ‘bad news god news’ result of Clarida and Waldman (2008. Is Bad News about Inflation Good News for the Exchange Rate. In: John Campbell, (Ed.), Asset Prices and Monetary Policy, Chicago: University of Chicago Press), Clarida and Waldman (2014. Bad News About Inflation is Good News for the Nominal Exchange Rate Under Optimal Monetary Policy: DSGE Theory and a Decade of Empirical Evidence). This is so even though in the long run of these models the nominal exchange rate must in expectation obey PPP. 相似文献

We show that the set of competitive equilibrium points of a pure exchange economy are the equilibrium points of a broader class of better-response demands than the usual utility-maximizing demand functions. The better-response demands are derived from assigning weights to all commodity bundles with higher utility than the current commodity bundle, with the greatest weights being placed on the commodity bundles with the highest utility gain. The usual utility-maximizing demand functions are then those in which the weight on the utility-maximizing bundle is one. We also show that these better-response demands belong to a large class of response maps that are generated by monotonic transformations of the utility functions and/or monotonic transformations of the weights assigned to the commodity bundles. 相似文献

This study investigates how unexpected announcements in Brazilian and U.S. macroeconomic indicators affect the term structure of nominal interest rates, as well as implicit inflation expectations and real interest rates. Using daily data from March 2005 to December 2012, we employ an extended Vector Error Correction Model to take into account nonstationarity and the long-term equilibrium among different maturities of those curves. We found empirical evidence that macroeconomic surprises, domestic (Brazilian) and external (U.S. American), which lead the market to believe that there might be a higher risk of inflation or an overheated economy, raise nominal interest rates, implicit expected inflation and real interest rates. Surprisingly, in relation to the efficient-market hypothesis, we found that some macroeconomic surprises have a lagged effect on the yield curves. We also tested the impact of the global financial crisis of 2007–09 and found that the crisis affected significantly the direction and magnitude of the responses to macroeconomic news. 相似文献
