In this paper we look at the impact of broad policy reforms on the levels of corruption. We use a structural break approach to identify country-specific time periods in which significant shifts in corruption levels take place. We then correlate these times of change with a set of covariates with specific focus on the impact of democratization, and trade and equity market liberalization. We find robust support for the hypothesis that episodes of reduction in corruption levels tend to be correlated with democratization and equity market liberalization. 相似文献

FX spreads and dealer competition across the 24-hour trading day 总被引:1,自引:0,他引:1
This study examines the impact of competition on bid-ask spreadsin the spot foreign exchange market. We measure competitionprimarily by the number of dealers active in the market andfind that bid-ask spreads decrease with an increase in competition,even after controlling for the effects of volatility. The expectedlevel of competition is time varying, highly predictable, anddisplays a strong seasonal component that in part is inducedby geographic concentration of business activity over the 24-hourtrading day. Our estimates show that the expected addition ofone more competing dealer lowers the average quoted spread by1.7% 相似文献

The components of the bid-ask spread: a general approach 总被引:22,自引:0,他引:22
A simple time-series market microstructure model is constructedwithin which existing models of spread components are reconciled.We show that existing models fail to decompose the spread intoall its components. Two alternative extensions of the simplemodel are developed to identify all the components of the spreadand to estimate the spread at which trades occur. The empiricalresults support the presence of a large order processing componentand smaller, albeit significant, adverse selection and inventorycomponents. The spread components differ significantly accordingto trade size and are also sensitive to assumptions about therelation between orders and trades. 相似文献

未来,当历史学家们回顾2010年这个夏天时,最值得铭记的历史事件应该是:中国超过日本,成为世界第二大经济体。总的来说,这是件大好事。中国的迅猛崛起,以及速度稍逊一筹的印度崛起,改善了数十亿贫困人口的生活,让他们成为全球经济的一员。 相似文献

Volatility in the foreign currency futures market 总被引:4,自引:0,他引:4
We examine the volatility implications of around-the-clock foreignexchange trading with transaction data on futures contractsfrom the Chicago Mercantile Exchange and the London InternationalFinancial Futures Exchange. We find higher U.S.-European andU.S.-Japanese exchange-rate volatilities during U.S. tradinghours and higher European cross-rate volatilities during Europeantrading hours. While the disclosure of private information throughtrading may partly explain these volatility patterns, we concludethat the increased volatility is more likely driven by macroeconomicnews announcements. An analysis of inter- and intraday dataalso reveals that volatility increases at times that coincidewith the release of U.S. macroeconomic news. 相似文献

The paper sets the neoclassical monetary business cycle model within endogenous growth, adds exchange credit shocks, and finds that money and credit shocks explain much of the velocity variations. The role of the shocks varies across subperiods in an intuitive fashion. Endogenous growth is key to the construction of the money and credit shocks because these have similar effects on velocity, but opposite effects upon growth. The model matches the data's average velocity and simulates well velocity volatility. Its Cagan-like money demand means that money and credit shocks cause greater velocity variation, the higher is the nominal interest rate. 相似文献
