In this paper, we model price dispersion effects in over-the-counter (OTC) markets to show that, in the presence of inventory risk for dealers and search costs for investors, traded prices may deviate from the expected market valuation of an asset. We interpret this devia- tion as a liquidity effect and develop a new liquidity measure quantifying the price dispersion in the context of the US corporate bond market. This market offers a unique opportunity tofstudy liquidity effects since, from October 2004 onwards, all OTC transactions in this marketfhave to be reported to a common database known as the Trade Reporting and CompliancefEngine (TRACE). Furthermore, market-wide average price quotes are available from MarkitGroup Limited, a financial information provider. Thus, it is possible, for the first time, to directly observe deviations between transaction prices and the expected market valuation of securities. We quantify and analyze our new liquidity measure for this market and find significant price dispersion effects that cannot be simply captured by bid-ask spreads. Wefshow that our new measure is indeed related to liquidity by regressing it on commonly-usedfliquidity proxies and find a strong relation between our proposed liquidity measure and bond characteristics, as well as trading activity variables. Furthermore, we evaluate the reliability of end-of-day marks that traders use to value their positions. Our evidence suggests that the price deviations from expected market valuations are significantly larger and more volatile than previously assumed. Overall, the results presented here improve our understanding of the drivers of liquidity and are important for many applications in OTC markets, in general. (authors' abstract)

The financial crises and bank runs in the past decade increased attention to the financial systems. In Turkey as in Europe banks are main financial intermediaries and financial crises occur mostly due to realization of risks in banks. Although liquidity risk is embedded into daily operations of banks unless controlled it may take banks into insolvency and even bankruptcy. This thesis aims to examine liquidity risk structure of Turkish banking sector. As a sample the domestic commercial banks in Turkey is chosen. The risk profile of the sector is examined by using a ratio analysis. The accounting figures in balance sheets and income statements of banks are employed for statistical analysis about liquidity risk of the sector. The means of liquidity ratios among different groups of banks are compared via analysis of variance. Moreover relation between liquidity risk and return in the sector is analysed by using panel data regressions.

In this paper, we test the hypothesis that the introduction of Taiwan Top 50 Tracker Fund (TTT) would impact the market liquidity of its underlying stocks. We address this issue by adopting several volume-based and price-based liquidity measures to present the multi-dimension of liquidity. Our empirical results show that after the introduction of TTT, the standardized trading volume decreases and the market becomes more volatile for the underlying stocks. Both the quoted spread and the effective spread widen in the post-introduction period. These findings suggest deterioration of market liquidity for the underlying stocks. We then further follow Lin et al. (1995) to decompose the effective spread to examine the changes in spread components. We find a significant increase in the adverse selection component in contrast to a slight decline in the order processing cost. Overall, we find evidence that the liquidity of the underlying stocks tends to deteriorate after the introduction of TTT primarily because there is an increase in the cost of informed trading. Our finding is consist with the prediction of Subrahmanyam (1991) where the migration of liquidity traders to the basket securities raises the portion of informed traders in the market of underlying stocks and tends to increase the adverse selection risk and reduce the market liquidity of the underlying stocks.

This paper documents how Swedish firms implemented and executed open-market sharerepurchases over the period 2000 to 2007 by using a unique hand-collected data set withdetailed information of each repurchase transaction. I find that my sample firms have a higherrepurchase fraction in the first half of the repurchase year. Analysis of liquidity of stocksoffers mixed results as the first proxy, turnover, improves in the second half of the program,whereas the Amihud measure of illiquidity indicates lower liquidity. Positive abnormalreturns following approval of the repurchase program is documented and large repurchaseprograms are associated with higher abnormal returns. My multivariate analysis indicates apositive correlation between abnormal return and repurchase size. Finally, I also find thatmanagers in repurchasing firms exhibit market timing skill, a skill which is more pronouncedfor firms with multiple programs. / This version: July 2009
