The economic benefits of market timing the style allocation of characteristic-based portfolios

Many exchange traded funds track simple characteristic-based equity portfolios such as the market capitalization, the fundamental value or the inverse volatility portfolio. This paper provides theoretical and empirical evidence for the economic benefits in exploiting the timing-gains that result from the time-varying relative performance of these characteristic-based portfolios. Under a factor model for expected returns, we show that this dynamic portfolio allocation can be efficient across the low-dimensional set of characteristic-based portfolios. We assess the out-of-sample performance on the S&P 100 universe over the period 1990–2013 and show gains in stability and significant positive risk-adjusted returns for the dynamic style portfolio. We conduct several robustness tests and extensions confirming the benefits of dynamic style allocation across characteristic-based portfolios.     

The impact of reduced pre-trade transparency regimes on market quality

This paper studies the effects of pre-trade quote transparency on spread, price discovery and liquidity in an artificial limit order market with heterogeneous trading rules. Our agent-based numerical experiments suggest that full quote transparency incurs substantial transaction costs to traders and dampens trading activity in an order-driven market. Our finding reveals that exogenous restriction of displayed depth, up to several best quotes, does not benefit market performance. On the contrary, endogenous restriction of displayed quote depth, by means of iceberg orders, improves market quality in multiple dimensions: it reduces average transaction costs, maintains higher liquidity and moderate volatility, balances the limit order book, and enhances price discovery.

The Impact of Exchange Rate Volatility on International Trade Flows

Despite the best efforts of economists, a basic paradox as to the impact of exchange rate volatility on trade flows remains unresolved at both the theoretical and empirical level. This paper surveys the vast literature in the area in an attempt to identify major issues which have contributed to the development of the debate and examine whether any general direction for consensus may be found.     

The impact of funding liquidity on market quality

This study analyzes market quality during the 2007–2008 credit crunch, by examining the impact of funding liquidity on market liquidity and price discovery of S&P 500 exchange-traded funds (i.e., S&P 500 depositary receipts [SPYs]) and index futures (E-minis). The empirical results show that funding liquidity affects market liquidity, and that the impact of illiquidity contagion between SPYs and E-minis was significant during the subprime mortgage crisis. In particular, the contagion effects between the two markets mediate the impact of funding illiquidity on market liquidity during the credit crunch. Considering the influences of other market factors on price discovery, we suggest that E-mini index futures made less contributions to price discovery during the credit crunch compared to normal periods. The empirical finding emphasizes the importance of the contagion effect between ETF and E-mini futures markets, when they suffer from external shocks.     

The role of oil futures intraday information on predicting US stock market volatility

This study investigates the role of oil futures price information on forecasting the US stock market volatility using the HAR framework. In-sample results indicate that oil futures intraday information is helpful to increase the predictability. Moreover, compared to the benchmark model, the proposed models improve their predictive ability with the help of oil futures realized volatility. In particular, the multivariate HAR model outperforms the univariate model. Accordingly, considering the contemporaneous connection is useful to predict the US stock market volatility. Furthermore, these findings are consistent across a variety of robust checks.

Impact of an unexplained component of real exchange rate volatility on FDI: Evidence from transition countries

The aim of this paper is to examine the impact of an unexplained component of real exchange rate volatility on FDI in transition economies. We make an attempt to overcome some problems associated with previous studies; the aggregation problem, inadequate measures of volatility, short-run focus and the endogeneity problem. Using a GARCH specification, we focus on long-run volatility, while we control for the endogeneity problem by applying SYS-GMM estimation. The obtained results show that the impact of the unexplained component of real exchange rate volatility on FDI differs among economic activities since 2000. As part of the re-estimation exercise, we use two alternative measures of volatility to avoid arbitrariness. The obtained results are to a large extent in accordance with the first one.

An Extreme Value Approach to Test the Effect of Price Limits on Volatility

Many stock exchanges around the world enforcing daily price limits on the amount asset prices can change to prevent the market from overreacting and to reduce volatility. Price limits are artificial boundaries set by market regulators who restrict price changes of a stock to a pre-specified range during a trading day or a single trading session. The primary aim of price limit rules is to stabilize the markets during panic trading, to moderate vitality by repressing excessive speculation, and to allow stocks to be traded at prices close to their fair value. However, their impact on the market is a somewhat unresolved issue （Harris, 1998）. Using a methodology of comparing volatility based on the extreme value technique, the authors empirically investigate the impact of price limits on the volatility of the Stock Exchange of Thailand. The empirical results support price limits advocates, suggesting that price limits rules moderate stock price volatility.

Effects of the short sale circuit breaker on the stock market

We provide new evidence on the effects of the recently introduced short sale circuit breaker, Rule 201, which triggers when the price of a stock drops more than 10 percent in a single day. The regulatory presumption is that the trigger should damper intraday price declines for affected stocks. However, our evidence suggests that this is not the case. The circuit breaker fails to reduce intraday volatility and intraday price declines, especially for the most volatile stocks in the market. Market quality measures based on liquidity and pricing efficiency are largely unaffected. Higher dispersion of investor opinion increases overpricing when the circuit breaker is in force. Price stabilization after stocks trigger the circuit breaker is shown for stocks that experience substantial price declines. Finally, post‐shock drift reduction is consistent with improved informational efficiency.     

The effect of nominal exchange rate volatility on real macroeconomic performance in the CEE countries

This paper analyzes the relation between nominal exchange rate volatility and several macroeconomic variables, namely real output growth, excess credit, foreign direct investment (FDI) and the current account balance, in the Central and Eastern European EU member states. Using panel estimations for the period between 1995 and 2008, we find that lower exchange rate volatility is associated with higher growth, higher stocks of FDI, higher current account deficits, and higher excess credit. At the same time, the recent evidence seems to suggest that following the global financial crisis, “hard peg” countries may have experienced a more severe adjustment process than “floaters”. The results are economically and statistically significant and robust.     

The impact of individual investor trading on information asymmetry in the Korean stock market

This paper examines the impact of individual investor trading on information asymmetry in the market. In particular, we examine the relationship between the trading volume by individual investors and the corresponding bid-ask spread in the Korean stock market, where the majority of the trading activity is driven by individual investors and therefore information asymmetry can be evident. We find that high trading activity by individual investors increases the bid-ask spread in a short investment horizon, suggesting that individual investors, as uninformed and unsophisticated traders, amplify the degree of information asymmetry in the market through trading.     

The impact of central clearing on the market for single-name credit default swaps

In this article, we revisit the impact of the voluntary central clearing scheme on the CDS market. In order to address the endogeneity problem, we use a robust methodology that relies on dynamic propensity-score matching combined with generalized difference-in-differences. Our empirical findings show that central clearing results in a small increase in CDS spreads (ranging from 14 to 19 bps), while there is no evidence of an associated improvement in CDS market liquidity and trading activity or of a deterioration in the default risk of the underlying bond. These results suggest that the increase in CDS spreads can be mainly attributed to a reduction in CDS counterparty risk.     

The impact of monetary policy on stock market bubbles and trading behavior: Evidence from the lab

We investigate the effect of monetary policy on stock market bubbles and trading behavior in experimental asset markets. We introduce the possibility of investing in interest bearing bonds to the widely used laboratory asset market design of Smith et al. (1988). Treatment groups face a variable interest rate policy which depends on asset prices, while control groups are subjected to a constant interest rate. We observe a strong impact of our interest rate policy on liquidity in the stock market but only a small impact on bubbles. However, we find that announcing the possibility of reserve requirements significantly reduces bubbles.     

Office Channeling and Its Impact on the Growth of Indonesian Islamic Banking Industry

The purpose of this paper is to analyze that the office channeling policy that based on Bank Indonesia＇s rule No. 8/3/PBI/2006 had an impact on the growth of Islamic banking industry in Indonesia. This research used ordinary least square regression to analyze the impact of office channeling policy on the growth of Indonesian Islamic banking industry. The variable used in this paper is office channeling which is used as a dummy variable, and margin deposit and non-performing financing （NPF） are also used as control variables. The indicators of the growth of Indonesian Islamic banking industry are asset and third-party funds. The result shows that office channeling does not have an impact on the growth of Islamic banking industry which is measured by asset growth and third-party funds growth. According to this result, Bank Indonesia should have an innovative policy to stimulate the Islamic banking industry growth in Indonesia.     

欧盟否认中国市场经济地位对中国及世界经济影响的剖析

研究目标：探究欧盟否认中国市场经济地位,对中国、欧盟及世界经济的宏观、产业以及贸易的影响。研究方法：将“非市场经济地位”折算为“反倾销等值税”,利用全球贸易分析模型针对欧盟对中国征收的进口关税进行计算。研究发现：欧盟否认中国市场经济地位不会缓解欧盟就业压力,反而使欧盟出口在中国总进口占比下降0.01个百分点;同时,全世界资源配置效率下降,进一步导致全世界整体福利下降;虽然欧盟否认中国市场经济地位使中国对欧盟出口减少约50.6亿美元,但中国向世界其他地区的出口量均有所上升;而且有利于中国产业结构优化,对供给侧改革有一定的激励作用。研究创新：将“非市场经济地位”折算为“反倾销等值税”。研究价值：在研究非数值变量时（如市场经济地位）,可利用其直接影响的变量（反倾销）造成的直接经济损失,折算为适当的指标变量（等值关税）。中国对世界经济的贡献和影响巨大,市场经济地位不容否认。
