The main purpose of this paper is to calculate the entropy of money in the space of Gross domestic product with the approach of econophysics and investigating the effect of stock market development on it. In this regard, by using annual data in the period of 1370-1398 in the framework of Smooth Transition Autoregressive Model (STAR), the asymmetric behavior of monetary irregularities around a threshold at different levels of stock market value as a variable of analysis is investigated. The results show that at low levels of current value of the stock market (the first regime), net capital inventory and budget deficit of governments have positive effects and the number of companies admitted to the stock exchange organization have a negative effect on monetary entropy. At high levels of current value of the stock market (Second Regime), net capital inventory has negative effect and government budget deficit continued to have a positive effect on monetary entropy. Based on the results of this study, it is clear that the dynamics of the stock market will reduce monetary entropy, which is itself an indicator of wasting and lacking of access to the resources.

This study investigated the factors that leads to economic uncertainty which may influence the petrochemical companies returns in various market conditions regarding their various levels of capital. To meet this object, we used quarterly data on government’s current expenditures, general government revenues, liquidity, GDP, and exchange rate, as the political variables for the years 1384-1397. Considering the type of available time series, we exercised the ARIMA-GARCH model to create an indicator to show the uncertainty of economic policies. We used the result to estimate the quantile regression model, along with other factors affecting corporate returns, including the price of the OPEC oil basket and the real rate of returns and market exchange rate. The results of this study indicated that in the bearish market, the greatest negative effect of each economic policy uncertainty is on the companies with lesser capital. Moreover, the intensity of this effect decreases as the market tends to change from bearish to bullish, and finally the economic policy uncertainty will have the least impact on companies with bigger capital.

The unstable state of macroeconomic indicators such as gross domestic product (GDP), investment, and inflation rate, as well as the disproportionate level of high volume of cash held by private individuals versus the low volume of liquidity in manufacturing firms, have always been a significant problem in Iran's economy. In this respect, the relationship among the stock market, bank deposits, and speculation in the foreign exchange market, and also, the central bank's role in directing liquidity between them to affect the macroeconomic indicators are important. The current study evaluates this subject for 1988–2018 using a system of simultaneous equations and the three-stage least squares (3SLS) method. The findings indicate that there has been a significant negative relationship among the stock market, bank deposits, and foreign exchange speculation. The stock market and bank deposits have had a significant positive effect on investment and GDP, and in contrast, foreign exchange speculation has shown a significant negative impact. Conversely, bank deposits have negatively impacted the consumer price index (CPI), whereas foreign exchange speculation has shown a substantial direct effect. Finally, despite the existence of a significant negative relationship between three financial markets in the Iranian economy confirmed by the obtained results, the central bank has forfeited a considerable portion of its potential effectiveness in directing liquidity between parallel financial markets to affect nominal and real economic indicators due to interest rate repression.

In recent decades, the effect of financial development on real sector growth has been discussed from different aspects. This paper focuses on financial structure and explains the role of bank-based and market-based financial structures on economic growth by classifying the literature. Using the FMOLS method for the period 1979-2016, the effects of financial structure and banking structure on per capita GDP and sectors’ growth (agriculture, industry, and services) in Iran are estimated. Empirical findings indicate that discriminating policies and bias in financial structure in favor of a specific sector has a negative effect on real sector growth, especially agriculture and industry. Therefore, in support of the design of a balanced financial structure, it is recommended that the state should avoid any intervention or discrimination in favor of a specific sector. In the case of banking structure, the findings show that increasing the financial strength of banks encourages economic growth.

The stock market is one of the most important infrastructures for economic development in developing and developed countries. The convergence of stock market returns reflects the interdependence of the economies of countries and the mobility of capital among them. This study aims to test the stock market price index convergence between OECD countries Philips and sul (2007) methodology over the period January 2007-Februrary 2017. The results show that the stock markets do not form a convergent cluster. However, there are three convergent clubs with one divergent market, Luxemburg. Also, the result of convergence test among clusters represents that the first and second clusters form a convergent cluster.

Energy, one of the most essential and important factors of production and the final product, has an important role in the growth and economic development. This research examines the dynamic relationship between financial development and energy consumption based on GMM estimation in 53 developing countries and 47 advanced countries over the period 2000-2014. The results showed the positive impact of direct foreign investment and national income on energy consumption in the two groups of countries. Energy prices had a completely opposite effect on energy consumption in developing and advanced countries. The results also indicated that in both developed and advanced countries the money market plays a more effective role in reducing energy consumption in comparison with the capital markets. While the effect of financial development through the money market on energy consumption is U- inverse shape in both groups of countries, this effect through the capital market is U-shape and U-shape inverse for developing countries and advanced countries, respectively. These results might have important policy implications for energy management policymakers and authorities to achieve sustainable development in different countries.

this paper following Lakonishok (1992) and Sias (2004), we examine the presence of herding behavior among active institutional investors, test the presence of momentum strategy (as a determiner of herding behavior) and the correlation between herding behavior and weekly, monthly and quarterly stock return, using time series data (2006 – 2008) in the Tehran Stock Exchange. Our findings confirm the presence of herding behavior among the institutional investors and show that its intensity is higher than the developed countries, but they reject the presence of momentum strategy and its role as a determiner of herding behavior. Furthermore, the results show that the herding behavior of institutional investors does not affect the market return and has no correlation with the past and future returns.

This paper uses daily data from the Tehran Stock Market (TSM) to illustrate the nature of stock market volatility in an undeveloped stock market. Although most studies suggest that a negative shock to stock prices will generate more volatility than a positive shock of equal magnitude there is no evidence of symmetric effect in TSM. The EGARCH model passes all the tests and appears to be the most adequate characterization of the underlying data generating process.
