The aim of this paper is to investigate the responses of stock, gold and foreign exchange markets in Iran, with an emphasis on the spillover volatility effects. For this purpose, the rate of return of variables is calculated by using the daily data of Tehran Stock Exchange price index, exchange rate and gold price during the period of 25 March 2009 to 18 July 2018. The estimated model investigates volatility spillovers in the markets using the VAR-BEKK-GARCH approach. The impulse-response functions are estimated by including the possibility of the asymmetry of the coefficients of the cross terms of the errors in MGARCH-type equations. The results show two-way volatility spillover between foreign exchange and stock markets, one-way volatility spillover from the foreign exchange to gold markets and one-way volatility spillover from the gold to stock markets. Moreover, the findings obtained from the impulse-response functions confirm the spread of uncertainty among the financial markets in Iran.

The results of many studies show that rigid regulations on product and labor markets are considered as a key factor in weakening the employment conditions and have led to high unemployment rates. Given the complicated regulations in the countries of the Middle East and North Africa (MENA), studying the great dynamics of deregulation can give useful guidelines for lawmakers and policy makers. The aim of this paper is to study the effect of deregulations of commodity and labor markets on the growth and the unemployment rate in 20 MENA countries using GMM method and Panel VAR approach during the period 2005 – 2017. The results of this study show that deregulation in product and labor markets in the short run will reduce economic growth, increase unemployment and lead to recession. But in the long run, it will increase economic growth and reduce unemployment. The labor market reforms, as opposed to product market reforms, do not lead to major dynamics in economic growth. For policy-making in MENA countries, deregulation in the product market has priority over the labor market, since it has a stronger impact on the wavelength and durability of the effects.

The aim of this study is to estimate the amount of underground economy as well as to determine the effect of tax policy on it in Iran. For this purpose, a Dynamic Stochastic General Equilibrium (DSGE) model is developed incorporating the underground economy. Quarterly data for 1360-1393 in Iran are used for estimation. The results show that on the average 23 percent of household consumption during the examined period is from underground goods, and about 17 percent of these goods are imported into the country through underground import or smuggling. Real average amount of smuggling and underground production in Iran during the considered period is estimated as 29023 and 141702.5 billion Rials, respectively. In addition, the results show that the average share of underground employment in total employment over the period is about 18 percent. The average tax evasion of consumption tax, import tax and wage tax is estimated about 17.8 percent of average government tax revenue during this period. Comparing the effects of four different tax shocks on underground economy also shows that the profit tax shock has the largest effect on underground economy, and after that is import tax shock. The effects of tax shocks show that the severity and duration of the impact of tax shocks on underground production is more than that of the formal economy.

Tracing the impact of exchange rate movements on prices is one the most important issues in monetary policy making. In this paper by applying a SVAR model to a quarterly data set spanning from 1990q1 to 2013q4, we assess the effect of exchange rate variations on domestic prices in Iran. In addition to exchange rate growth and output gap, the growth of liquidity, consumer, producer, and import prices are also included in the model. Our findings suggest that: i) There is an asymmetry in exchange rate pass-through in Iran. ii) Although small appreciations have no effect on prices, depreciations, especially large ones, are significantly effective. iii) The effect of exchange rate on consumer price growth, lasts for relatively longer periods of time.

Applying the SVAR method of 'Kilian' to the monthly data over the period of 1973-2007, in this paper, we decompose oil price shocks into five structural shocks, namely, Iran political supply shocks, OPEC political supply shocks, non- OPEC supply shocks, world demand shocks, and oil specific demand shocks. Then, estimating separate OLS regressions, based on annual data of Iranian Economy, the impact of these structural shocks on main macroeconomic variables, and outbreak of Dutch disease is studied. This paper finds that the symptoms of Dutch disease have not been observed, following different structural shocks, except for Iran political supply shocks. Owing to dominant role of government in production, and export of oil in Iran, it is evident that the effect of oil price shocks, to a large extent depends on the government conduct, and the Dutch disease is not an inevitable reality for the Iranian economy.

The main concern in all economic activities is to obtain maximum output using minimum resources. That is the reason why the wages should be set with respect to productivity. To what extent the wages in practice are set in accordance with productivity is the main subject of our study. We use the survey of large manufacturing establishment’s data set for twenty two industries during 1373-1384 (1996-2005) to estimate the wage equation. Our findings indicate that there is some significant relation between wage, productivity, skills and education. However, labor productivity has trivial role in wage determination in comparison to other explanatory variables

In this research, we test for the factors that determine private saving in the Iranian economy during 1968-2001 using auto regressive distributed lag model (ARDL). In this model, we examine the effects of factors such as disposable income, social security costs, unemployment rate, long term interest rate, inflation, Gini coefficient, ratio of the value of stocks exchanges to the terms of trade GDP, and a dummy variable for the post-war years. The results show positive effects of income, improvement of income distribution, and more developed financial markets, and negative effect of social security costs on the saving of private sector.
Our results also indicate that the best and the most secured way to increase private saving is to improve financial markets performance that leads to a better absurbtion of saving and to an increases in investment possibility.
