中国通货膨胀预期记忆性研究——基于2003-2017年央行数据的实证分析

基于央行发布的居民对下季度物价预期数据,构建净差额法、正态分布、均匀分布以及逻辑分布下的通货膨胀预期,实证检验不同分布下通胀预期的记忆性,并在此基础上研究北京、河北、江西、云南等四个省市之间记忆性差异及其微观原因.结果表明:当我国居民通胀预期服从均匀分布时,通胀预期有可能存在记忆性,并且具有"长记忆"特征.其中北京通胀预期记忆性最短,其次是河北和云南,江西通胀预期记忆性最长.这种通胀预期记忆性的差异来源于各省市居民对未来收入信心、金融参与程度以及人均收入等微观因素的差别.     

Impacts of the financial crisis on eurozone sovereign CDS spreads

We study the variation of sovereign credit default swaps (CDSs) of eurozone countries, their persistence and co-movements, with particular attention given to the impact of the financial crisis. Specifically, using a dual fractional integration model, we test the evidence of long memory for CDSs of ten eurozone countries. Our analysis reveals that price discovery processes satisfy the minimum requirements for a weak form of efficiency for sovereign CDS markets, even during the crisis. In contrast, we document the spreading out of persistent CDS uncertainty among the peripheral economies with its outbreak. We provide evidence that CDS uncertainty has implications for the pricing of sovereign risk including that of core countries in the crisis period. Finally, we present the potential spillover effects utilizing a dynamic conditional correlation model and show that, with the collapse of Lehman, the probability of a contagion increased across all countries and became more explicit for peripheral economies as the sovereign crisis took on a new dimension.     

MENA stock market volatility persistence: Evidence before and after the financial crisis of 2008

The global financial crisis began with a financial meltdown in the United States in early 2008 and then it had spread to the rest of the world. In this paper we test whether the MENA equity market volatility presents a different behavior before and after the financial crisis of 2008. Using long range dependence techniques we test for long memory in the returns, absolute and squared returns of the MENA equity markets. We subject the series to unit root tests that allow for structural breaks and use the Bai and Perron (1998, Econometrica, 66, 47; 2003a, J. Appl. Econometrics, 6, 72; 2003b, Econometrics J., 18, 1) to test for multiple breaks in the mean returns. The results indicate that the volatility measures represented by absolute and squared returns show evidence of long memory for the full and subsample periods, while the returns show a weak evidence of long memory. Considering the shift dates and corresponding to the 2008 financial crisis, the returns and volatility measures display less evidence of long memory in the after crisis period as opposed to the before crisis period. The change in the returns and volatility dynamics of these markets was due to financial and economic conditions that took place in the MENA region after the crisis.

Long memory or structural breaks: can either explain nonstationary real exchange rates under the current float?

This paper considers two potential rationales for the apparent absence of mean reversion in real exchange rates in the post-Bretton Woods era. We allow for (i) fractional integration and (ii) a double mean shift in the real exchange rate process. These methods, applied to CPI-based rates for 17 countries and WPI-based rates for 12 countries, demonstrate that the unit-root hypothesis is robust against both fractional alternatives and structural breaks. This evidence suggests rejection of the doctrine of absolute long-run purchasing power parity during the post-Bretton Woods era.     

The numbing effect of mortality salience in consumer settings

Nationwide Insurance and Johnnie Walker Scotch aired advertisements that encouraged people to contemplate death. What are the immediate emotional and perceptual outcomes of such advertisements? With five studies, thinking about death was found to attenuate emotional reactions and perceptions, a novel finding in the literature. This attenuation was observed with neural and self‐report measures along with retrospective and prospective assessments of emotion and is an outcome not yet investigated in mortality salience research. Contemplating death dampened people's expectations of emotion in a future consumption experience and diminished the attractiveness of the experience. Similarly, contemplating death affected backward‐looking assessments of emotion, for example, when nostalgic memories are brought to mind. Importantly, this dampening effect of mortality salience was replicated with advertisements that portrayed death‐related concepts and attenuated emotional reactions to subsequent advertisements.     

Ma(r)king memories: exploring embodied processes of remembering and forgetting temporal experiences

Based on in-depth interviews with nine tattoo consumers, participant observation at a tattoo studio, a tattoo consumption diary, and photography, we investigate embodied processes of remembering and forgetting temporal experiences. We unpick participants’ experiences of combatting the fragility of memory, negotiating which temporal experiences to remember or forget, and constructing temporal order through their tattooed bodies. These insights are enriched theoretically with reference to Ricoeur’s ideas concerning time, narrative, and memory. By focusing upon the embodied dimensions of memory work, we contribute fresh insights into the underexplored relations between bodies, time, and consumer culture. Furthermore, we indicate the continuing significance of temporal continuity, durability, and the past in accelerating Western cultures. Finally, we elucidate the importance of also attending to “absences” in consumer research. We conclude by considering the wider implications of our findings for better understanding an accelerating, liquid, and unstable consumer culture, beyond the context of tattooing.

谣言的建构：“毛人水怪”谣言再分析

本文介绍了20世纪中期大范围传播的“毛入水怪”谣言,指出谣言的实质是一个作为集体记忆存在的传说,在一些特定的历史事件中被有意无意地激发,在大规模的人口聚集与流动中广泛传播。通过分析几次谣言形成的过程及其背景,本文指出,大规模谣言的形成症结是民间的恐慌心态与不满情绪,正确理解谣言背后的深层社会问题,缓解民怨,是防止谣言最好的办法。
