Capital structure decisions have been one of the most important issues of the corporate finance literature. Theoretically, it is also expected that liquidity has an important effect on companies' capital structure. In this research, the casual relationship between financial leverage and liquidity was investigated using panel data in listed firms of Tehran Stock Exchange during 2006-2010. To do so, 108 listed firms of Tehran Stock Exchange were selected as the sample of the study and bid ask spread has been used as a criterion for liquidity measurement. In addition, F and Hausman tests were applied to select the best model of the panel, fixed effects and stochastic data. The findings showed a significant relationship between financial leverage and liquidity in Tehran Stock Exchange. In other words, financial leverage has a reverse effect on liquidity and on the other hand, liquidity has a positive and direct effect on financial leverage. Manuscript profile

The purpose of present paper was to examine the relationship between central bank independenceand inflation rate in Iran over 1960-2008. First, central bank independence has been accomplished through threeindices including legal and real CBI indices and turnover rate of central bank governor index. Then, AugmentedDickey-Fuller test for model stationary of variables has been done by applying Eviews software. In addition, therelationship among the central bank independence indices and average inflation rate and its variability in Iran’seconomy has been investigated using Eviews and Microfit softwares. Necessary data for calculating CBI indexwere obtained from Cukierman criteria (LCBI). Furthermore, real CBI index was gathered via standardquestionnaire and turnover rate of central bank governor index data were collected through library survey. Theresults showed a negative relationship among real CBI and inflation and its variability. The relationship betweenlegal CBI and inflation was also negative, but its relationship with inflation variability was not statisticallysignificant. Also, a positive relationship between turnover rate of central bank governor index and inflation ratewas observed, but negative relationship was seen between turnover rate of central bank governor index andinflation rate variability.
