This study aims to introduce the microstructure approach to the exchange rate as the 4th generation of exchange rate models and to apply it in a simulation model to study the effects of transparency of macroeconomic data on exchange rate fluctuations. The microstructure approach to the exchange rate is developed to include decentralized and multi-layer structure of currency markets along with information complexities in this market and the role of trading mechanisms in exchange rate determination. After introducing this approach, we have developed our theoretical model to use it for simulation. In this simulation, we have studied the effects of transparency of macro data release on exchange rate fluctuation. To achieve this goal, we have used two variables of “delay in macro data release” and “error in macro data release”. Our simulation results show that an increase in macro data release delay leads to higher volatility of The exchange rate. This is because of increasing uncertainty for economic agents. In addition, an increase in macro data release delay leads to a farther delay in responsiveness of the exchange rate to movements in its macro fundamental variables. Although we have found a non-linear relationship between the “error in macro data release” variable and exchange rate volatility, the magnitude of this effect is less than the effect of the “delay in macro data release” variable on exchange rate volatility. Based on our results, we recommend that to have lower exchange rate volatility, authorities should increase the transparency of macroeconomic data releases and especially they should lower the delay in macro data releases.

The aim of this paper is to investigate the relationship between Stock, gold coin and currency markets (as domestic markets), as well as, oil and gold markets and the U.S.A and European stock markets (as international markets) over the period of April 2001 to September 2013 using the Markov Regime Switching model and volatility spillover analysis. The empirical results in domestic markets showed that in low return regime, there is no significant spillover between markets so; the estimated value of spillover index is about 7.8 percent. In contrast, the value of spillover index in high return states is about 42 percent. Also, the results showed that when the world equity markets are in regime zero (low return regime), the gold market acts as an intermediary for the transmission of shocks from global markets to asset markets in Iran. In contrast, when the world equity markets are in regime one (high return regime), the oil market acts as a transmission channel of shocks.

Given the importance of identifying the relationship between exchange rate and trade balance in adoption of appropriate economic adjustment policies and the requirement of accurate estimation of elasticity of trade balance to income and price changes for proper timing of such policies, in this study the effect of domestic and foreign income and real exchange rates on the Iranian trade balance has been investigated. Moreover, the reactions of trade balance to changes in the variables of interest have been estimated using time varying parameter models over the period of 1338-1389.The results show that the coefficients of the estimated model are not constant over the time and they are influenced by structural changes such as: oil price shocks, economic policies and exogenous shocks such as the imposed war and the Islamic revolution. By comparing the price elasticity of the balance of trade and the real exchange rate, it can be seen that by increasing real exchange rates during the period of 47-50 and 56-67, the price elasticity is positive and becomes negative when real exchange rates reduce.

Abstract The aim of this paper is to investigate the behavior of stock, exchange and gold coin markets and their correlations structure by using the DCC-GARCH model and the daily data for the period from 23 July 2011 to 22 September 2013 in Iran. Results show that there is a high correlation between returns of Exchange rate and gold coin. But the correlation between returns of stock market index and Exchange rate or gold coin is low. Policy implications on portfolio strategies under DCC model results are also discussed.

The exchange rate is an important economic variable which affects other macroeconomic variables through different channels. This article estimates the effects of exchange rate shocks on macroeconomic variables of Iranian economy by applying Bayesian VAR method and using different prior functions like Minnesota and SSVS. The endogenous variables of the model are market exchange rate, monetary base, GDP deflator and GDP. The only exogenous variable of the model is the oil revenue of Iran. According to the result of the model, the BVAR-SSVS method offers the most precise forecast and OLS method has the least forecast power. At last, using the impulse response function, the effects of one unit shock in exchange rate on other macroeconomic variables has been assessed. The most important finding of this article is that, based on our data for Iranian economy, currency devaluation causes GDP to decline.

Considering the pivotal role of stock market in the process of economic development, this research focuses on the relationship between the variables of exchange rate, interest rate, oil price shock and overall price index of Tehran Stock Exchange. For this purpose, we have applied three different methods of Toda and Yamamoto causality test (1995), Granger vector error correction causality test (1987) and Pesaran, Shin and Smith’s (2001) Auto Regressive Distributed Lag (ARDL). The empirical findings show that there is a long-run relation between the variables of the stock price index, exchange rate, inflation rate, interest rate and oil price shock. Based on Toda and Yamamoto causality test, there is a one-way causality from variables of exchange rate, inflation rate and interest rate to stock price index, and from stock price index, exchange rate and interest rate to inflation rate, as well as from interest rate to exchange rate. The results of Granger vector error correction test showed that there is a short run causality from exchange rate, inflation rate and interest rate to stock price index and a long run causality from exchange rate, inflation rate, interest rate and oil price shock to stock price index.

This study aims at investigating the impacts of increased export price of agricultural products on macroeconomic variables of Iranian Economy. To get the objective, Computable General Equilibrium (CGE) and Social Accounting Matrix (SAM) of 1380 was used. The results showed that with increase in export price of agricultural commodities, irrespective of exchange rate, GDP, private investment rate and tax revenues will increase, however, production and consumption of commodities will decrease under flexible exchange rate and will increase in nonflexible exchange rate regime. It was also revealed that investment use of commodities tend to decrease under flexible exchange rate and it is expected to increase as nonflexible exchange rate policy is imposed. Agricultural and nonagricultural prices will also decrease (increase) in flexible (nonflexible) exchange rate conditions.
