FOREIGN EXCHANGE RATE EXPECTATIONS: SURVEY AND SYNTHESIS

Abstract.  This paper reviews the empirical literature on foreign exchange rate expectations. Prominent issues are the forward premium puzzle, expectations formation in financial markets, heterogeneity of expectations, market microstructure, time-varying risk premiums and forecast performance. Although much has been learned in each field, this survey highlights the areas of research in which our understanding of the mechanism of exchange rate expectations is still incomplete. Our survey suggests that both irrational expectations and time-varying risk premiums account for the forward discount anomaly, that long-term expectations reverse towards their long-run equilibrium values and that heterogeneous behaviour of market participants has the potential of explaining some of the empirical regularities in the international finance literature.     

An empirical investigation of investor expectations in the currency market

Using a new theoretical model of investor expectations in the foreign exchange market, this research finds investor forecasts to be rational. For instance, expectations are not characterized by fat-tailed distributions that might reflect optimistic bubbles and panic. They are also found to rationally predict a correlation between exchange rates and political factors such as modeled “pain” indexes and currency bands. Most importantly, the model detects an ex-ante investor prediction of a small probability of a large currency change that empirically explains ex-post forecasting biases.     

Web reviews influence on expectations and purchasing intentions of hotel potential customers

The objective of the paper is to study the impact that hotel guests reviews posted on consumer-generated websites have on the consumer decision-making process and service expectations.An experimental study has been conducted to test the hypotheses and the research question. 349 young adults were involved in an online survey that asked to imagine searching for a hotel and reading other customers’ reviews of a hypothetical chosen hotel. Three scenarios were created by studying a few comments posted by customers on the main websites used by tourists.Results show a positive correlation between both hotel purchasing intention and expectations of the customers and valence of the review. On the contrary, the presence of hotel managers’ responses to guests’ reviews has a negative impact on purchasing intentions.The study enriches the stream of research on word-of-mouth in the hospitality industry and analyses a new operational problem for lodging managers. Hotels should reply to online customer reviews or not?     

Managing Service Expectations in Online Markets: A Signaling Theory of E-tailer Pricing and Empirical Tests

Expectations play a significant role in determining customer perceptions and satisfaction. Accordingly, retailers seek to manage customers’ service expectations. However, the tangible signals of service quality that are available to brick-and-mortar retailers (such as location, store appearance, and salespersons’ behavior) may not be available in online markets. Using a signaling model, we obtain conditions when Internet retailers (e-tailers) use price to manage their customers’ service expectations. In contrast to extant theory, we find that it is possible for both low and high service e-tailers to use price in signaling their service levels. Further, we develop an appropriate deductive test of our theory based on price-ending patterns as an artifact of the signaling process. Based on this test, we find evidence that e-tailers indeed manage service expectations using price. Interestingly, we also find preliminary evidence that suggests customers implicitly associate price-ending patterns with a retailer's expected service level. We discuss several other implications of our findings for researchers and managers.     

A comparison of the information in the LIBOR and CMT term structures of interest rates

We investigate the information contained in the London Interbank Offered Rate (LIBOR) and the U.S. Constant Maturity Treasury (CMT) term structure of interest rates and report three novel findings. First, we document that the information contained in term structures are significantly different from one another. Second, we provide evidence of a significant change in the nature of this difference as the financial crisis began. Third, we find that the significant changes in the information content of CMT and LIBOR are consistent with significant shocks to credit default swap rates and tenor swap rates.     

市场预期及其影响因素与人民币汇率波动关系分析

本文构建了一个包括市场预期及其影响因素的理论框架,在此框架下研究了这两类因素与人民币汇率波动的关系。采用两阶段最小二乘法对此理论框架进行实证,得出的结论是:市场预期是推动人民币汇率在2001年1月～2009年12月期间走强的重要因素。中国人民银行外汇市场干预活动、上一期人民币汇率、中美利差变动和2005年人民币新汇率制度改革等因素在不同方向上改变了市场预期,从而间接影响了人民币汇率走势。     

房价预期与城镇居民家庭股市参与——理论探讨与微观经验证据

本文基于中国家庭金融调查数据,通过构建理论模型和实证检验分析了房价预期与家庭股市参与的关系,考察了行为金融偏差在房价预期影响股市参与过程中的作用,并根据背景风险、社会网络和户主特征进行异质性分析。结果表明:(1)房价上涨预期通过降低居民家庭的股票收益率预期和增加住房资产,进而降低居民家庭的股市参与概率和参与程度;(2)“心理账户”以及“有限关注”的存在显著弱化了房价上涨预期对家庭股市参与的负向作用;(3)房价上涨预期对股市参与概率和参与程度的负向作用在收入风险更高、健康状况更差、社会网络水平较低以及受教育程度偏低的家庭中更大。因此,稳定房价预期能够通过提升家庭股市参与,进而从需求角度促进股票市场的健康发展。     

The information in the term structure of German interest rates

This paper tests the Expectations Hypothesis (EH) of the term structure of interest rates using new data for Germany. The German term structure appears to forecast future short-term interest rates surprisingly well, compared with previous studies with US data, while it has lower predictive power for long-term interest rates. However, the direction suggested by the coefficient estimates is consistent with that implied by the EH, that is when the term spread widens, long rates increase. The use of instrumental variables to deal with possible measurement errors in the data significantly improves regressions for the long rates. Moreover, re-estimation with proxy variables to account for the possibility of time-varying term premia confirms that the evolution of both short and long rates corresponds to the predictions of the EH and that most of the information is in the term spread. These results are important as they suggest that monetary policy in Germany could be guided by the slope of the term structure.     

Anticipated fiscal policy and adaptive learning

The impact of anticipated policy changes when agents form expectations using adaptive learning rather than rational expectations is considered. Agents are assumed to combine limited structural knowledge with a standard adaptive learning rule. These issues are analyzed using two well-known set-ups, an endowment economy and the Ramsey model. In our scenario there are important deviations from both rational expectations and purely adaptive learning. The approach could be applied to other frameworks.
