量化宽松对世界新兴经济体影响及中国对策

在对主要发达国家实行的量化宽松货币政策措施基础上,通过分析量化宽松货币政策传导机制,得出量化宽松政策将会降低新兴经济体债券收益率、促使新兴经济体货币升值、加大新兴经济体流动性过剩压力、加大新兴经济体通货膨胀压力等结论,认为这些不利影响必然会影响到中国经济稳定。因此,我国应提高人民币存贷款利率、完善人民币汇率形成机制、加强对国际资本流动的监管、调整存款准备金率,以应对中国可能面临的危机。     

The impact of exchange rates on stock market returns: new evidence from seven free-floating currencies

This paper provides evidence of a significant exchange rate effect on stock index returns using data from seven selected countries practicing free-floating exchange rate regimes. This research uses parity and asset pricing theories, thus placing it within the monetary-cum-economics framework for international asset pricing. In this study, we apply a system of seemingly unrelated regression to control for unobserved heterogeneity and cross-sectional dependence. The findings constitute evidence of a statistically significant exchange rate impact on stock index returns across selected countries. These findings can be considered as falling under the arbitrage pricing approach of the international capital asset pricing model of Solnik who also used the parity-theoretical framework on exchange rate determination.     

The scapegoat theory of exchange rates: the first tests

The scapegoat theory of exchange rates (Bacchetta and van Wincoop, 2004, Bacchetta and van Wincoop, 2013) suggests that market participants may attach excessive weight to individual economic fundamentals, which are picked as “scapegoats” to rationalize observed currency fluctuations at times when exchange rates are driven by unobservable shocks. Using novel survey data that directly measure foreign exchange scapegoats for 12 exchange rates, we find empirical evidence that supports the scapegoat theory. The resulting models explain a large fraction of the variation and directional changes in exchange rates in sample, although their out-of-sample forecasting performance is mixed.     

Emerging market bond spreads: The role of global and domestic factors from 2002 to 2011

We address the importance of external versus domestic conditions in determining emerging market bond (EMBI) spreads. Using principal components, we derive a measure of global risk aversion, which is shown to have a significant and, when interacted with a country's foreign debt to GNI ratio, nonlinear effect on these bond spreads. Our model, estimated using Pooled Mean Group techniques, which also incorporates country-specific variables (foreign debt, fiscal policy, debt servicing and political risk), is able to track developments in emerging market bond spreads over the period May 2002 to October 2011 quite well. From mid 2002 to mid 2007, the model suggests that just over two thirds of the decline in these spreads on average reflected improved fundamentals, with the rest due to easy credit conditions. During the 2008 crisis, virtually all of the run-up in emerging market spreads was due to the large increase in our measure of risk aversion. A model of the measure of risk aversion is also estimated, which identifies as its key drivers, the outlook for growth in the major OECD and large non-OECD economies as well as US credit supply conditions.     

The market microstructure approach to foreign exchange: Looking back and looking forward

Research on foreign exchange market microstructure stresses the importance of order flow, heterogeneity among agents, and private information as crucial determinants of short-run exchange rate dynamics. Microstructure researchers have produced empirically-driven models that fit the data surprisingly well. But FX markets are evolving rapidly in response to new electronic trading technologies. Transparency has risen, trading costs have tumbled, and transaction speed has accelerated as new players have entered the market and existing players have modified their behavior. These changes will have profound effects on exchange rate dynamics. Looking forward, we highlight fundamental yet unanswered questions on the nature of private information, the impact on market liquidity, and the changing process of price discovery. We also outline potential microstructure explanations for long-standing exchange rate puzzles.     

The behaviour of asset return and volatility spillovers in Turkey: A tale of two crises

This paper examines return and volatility spillovers between the Turkish stock market with international stock, exchange rate and commodity markets. Our aim is not only to examine spillover behaviour with a large emerging market but also to examine cross—asset spillovers and how they vary across two periods of financial market crisis; the dotcom crash and the liquidity-induced financial crisis. This is to be compared with existing work that typically focuses on industrialised countries or single asset markets only. Using the spillover index methodology we uncover an interesting distinction between these two periods of markets stress. Over the dotcom period spillovers are largely between the same asset class, notably two exchange rate series and two international stock markets series. However, in the period including the financial crisis, spillovers both increase and cross asset types and suggest a much greater degree of market interdependence. Understanding this changing nature in spillovers is key for investors, regulators and academics involved in theoretical model development.     

On the determinants of “small” and “large” foreign exchange market interventions: The case of the Japanese interventions in the 1990s

During the past 30 years, central banks have often intervened in foreign exchange markets, and the magnitude of their foreign exchange market interventions has varied widely. We develop a quantitative reaction function model that renders it possible to examine the determinants of “small” and “large” interventions. We apply the model to analyzing the intervention policy of the Japanese monetary authorities (JMA) in the yen/U.S. dollar market during the period from 1991 through 2001. To this end, we use recently released official data on the foreign exchange market interventions of the JMA. We find that the JMA tended to conduct large interventions when the yen/U.S. dollar exchange rate drifted away from an “implicit target exchange rate.”     

The effect of macroeconomic news on beliefs and preferences: Evidence from the options market

We examine the effect of regularly scheduled macroeconomic announcements on the beliefs and preferences of participants in the U.S. Treasury market by comparing the option-implied state-price densities (SPDs) of bond prices shortly before and after the announcements. We find that the announcements reduce the uncertainty implicit in the second moment of the SPD regardless of the content of the news. The changes in the higher-order moments, in contrast, depend on whether the news is good or bad for economic prospects. We explore three alternative explanations for our empirical findings: relative mispricing, changes in beliefs, and changes in preferences. We find that our results are consistent with time-varying risk aversion.
