For this purpose, two hypotheses were determined and the annual data of 30 companies of the Tehran Stock Exchange in the period 2008-2020 were used to test the hypotheses. To test the hypotheses, the neural network method optimized with the Jaya optimization method was used to examine the effect of the studied variables including firm size and growth ability, risk growth, asset return, equity return, and financial leverage. Analysis using neural networks is used to isolate and clarify the effects of each of the studied variables. The analysis of the neural network showed that the three variables, exchange rate, interest rate, and stock price are very important in the process of changes in merger and acquisition activities in the country. Exchange rate fluctuations in particular have a very elastic effect on mergers and acquisitions, indicating that price ...

Recent years have witnesses an increase level of engrossing foreign direct investment as a mechanism in these countries to settle down the problem especially in the East and South-East Asian countries. Foreign direct investment, in addition to repairing savings- investment gap, facilitates the process of economic growth in developing countries through technology transfer and creating spillover and external consequences effects. Increasing the openness degree and reduced trade restrictions on goods and services imports will boost the impact of FDI on the economic growth of the host country. By applying the endogenous growth model, this study seeks to examine the synchronous relationship between trade liberalization and FDI on economic growth in some selected Developing oil-exporting Countries (Algeria, Brazi...

For this purpose, a sample of 350 firm-years during the year 2006 to 2010 was reviewed and was tested. To determine the appropriate method for estimating regression models and hypotheses testing, we used the F-Limer test and Hausman test which in both, the fixed effects (panel method) was used to estimate the models. In the present study, the ratio of Tobin's Q (market value) (TQ), Price to Earnings (P/E) and market value to book value (M/B) have been used as market measures of corporate performance evaluation. The results indicate that there is negative and significant relationship between weighted average cost of capital (WACC) and the ratios of price to earnings and market value to book value. But significant relationship between the weighted average cost of capital and Tobin Q ratio has not been obser...

The theoretical framework is based on this assumption t hat the Technical progress is divided to two sectio ns; first section is the specified technical progress and sec ond section is the unspecified technical progress. This study uses annual time series data (1961-2007) and unit root tand analyze them using Auto Regressive Distrib uted Lag (ARDL) model by Pesaran et. al. (2001). This co-int egration technique accommodates potential structura l breaks that could undermine the existence of a long-run re lationship between labor productivity in the agricu ltural and its main determinants. Together the independent variabl es explained 92% of the variance in the dependent v ariables. The remaining 8% was due to unidentified variables. In relation to that, we can con...

Volatility is one of the factors that expose this loss to variations. Stock volatility is a means of displaying the degree of uncertainty about future variations in stock returns. With increased volatility, stock price is more likely to increase or decrease while the situation is different for the individual who holds the purchase or sale option. The present study aims to determine the maximum loss of stock option contract over a period of time due to stock price movement opposite to the expectations and unexercised contract. To this end, stock option prices were calculated for 48 companies based on the computation of volatility and the standard error of estimate using software and binomial tree model. The results of this descriptive study show that the maximum loss induced by unexercised stock option contract does not exceed the price paid for the contract; however,...

Therefore, the desired and effective performance of banks can create important effects on the development of different economic sectors and increase in the quantitative levels of the output. This study attempts to examine the effect of liquidity risk on the performance of commercial banks using of panel data related to commercial banks of Iran during the years 2003 to 2010. In the estimated research model, two groups of bank-specific variables and macroeconomic variables are used. The results of research show that the variables of bank's size, bank's asset, gross domestic product and inflation will cause to improve the performance of banks while credit risk and liquidity risk will cause to weaken the performance of bank.

For this purpose, a sample of 80 companies were investigated and analyzed among the companies listed in the Tehran Stock Exchange during the years 2006 to 2010. In this study is used the variables of earnings per share (EPS), price to earnings ratio (P/E) and the ratio of market value to book value of equity (M/B) to evaluate the market ratios of performance evaluation of companies. The research results indicate that earnings per share has significant and positive effects on stock return of current year, but on the stock return of future year has positive and bound line effects. Also obtained results show that the variables of price to earnings ratio and market value to book value ratio statistically have significant and negative effects on stock return of current and future year.

We use an augmented neoclassical production function type and apply VECM methodology to estimate the short and long-run effects. The results show: negative effects of non-oil export on non-Export output, while capital stock and labor force have positive effects on non-Export GDP.

In this study, the effect of monetary policy tools including interest rate, exchange rate and money supply on the variables of monetary policy targets including inflation and output is examined through VECM methodology over the period 1989:2-2007:2. Our findings show that in long-term, monetary supply is the most important variable influencing the price followed by the variables of output and exchange rate, respectively. Exogenous-being of interest rate indicates that this channel is underdeveloped and there is no monetary policy rule like Taylor rule in Iran's economy.
