study of price trend in iran, showed that general level of prices is rising continually during time. an inflation situation has effect on most economic variables. therefore investigation of effective factors and variables on inflation is important. exchange rate and gap in product are factors which affect inflation. in this paper the impact of exchange rate shocks and gap on inflation in iran’s...

in this study, the relationship between inflation and economic growth of iran is conciliated with a perspective on uncertainty of inflation. we use a generalized autoregressive conditional heteroskedasticity (garch) model that make possible this advantage that conditional variance of error term changes along the time, also, vector error correction model (vecm) is stable. for surveying the co-in...

In monetary unions of the European type the reduction in exchange rate uncertainty is not able to explain the differences in the economic performance of member countries. It is shown that traditionally unstable countries like Portugal and Ireland benefit significantly from a decrease in inflation and interest rate uncertainty while traditionally stable countries do not. The reduction in politic...

in macroeconomic studies, social welfare is assumed as a function of inflation and unemployment. although the social welfare function which is dependent to unemployment and inflation variables has been used widely in macroeconomic theories, but this relation needs to be tested through empirical observations. this paper, using variables such as to economics of happiness area and subjective wellb...

the purpose of present paper was to examine the relationship between central bank independence and inflation rate in iran over 1960-2008. first, central bank independence has been accomplished through three indices including legal and real cbi indices and turnover rate of central bank governor index. then, augmented dickey-fuller test for model stationary of variables has been done by applying ...

The real rate of interest indicates borrowing costs (or the return on an investment in financial assets), disregarding price increases. The expected real interest rate is important to investments, consumption and savings, and is therefore significant in the evaluation of economic prospects. The problem is that since the inflation expectations of investors and borrowers are not known, it cannot ...

inflation rates have risen around the woiid over the last 20 years the impact of inflation has become a topic of widespread interest, Evidence suggests that higher inflation imposes real costs on society by leading to increased uncertainty about futur-e inflation and, as a result, a misallocation of resources,’ This article examines the impact of inflation uncertainty on the allocation of labor...

This study provides cross country robust evidence on interdependencies among inflation, output growth and respective uncertainties for the current era of low inflation policies. We attribute the extant empirical disagreement on these relations to the fact that long sampling periods and single economies are typically considered for analysis. In this study, VARX-MGARCH-M models are estimated for ...

the current study addresses an estimation of investor's optimal portfolio under conditions of uncertainty by using a combination of artificial neural network and markowitz models. for this purpose, such assets as stock prices, house prices, coin and bonds price are used with monthly data over the period 1378-1392. three variables including inflation uncertainty, oil uncertainty and free ma...
