Rational expectations are at the heart of the DSGE models maintained by central banks. A key equation which governs the evolution of prices in those models is the New Keynesian Phillips (NKPC) curve, in which today‟s rate of inflation is linked to expected future inflation. Expected future inflation is in turn modeled using rational expectations, which operationally means that forecast errors a...

this paper tries to survey and estimate non-accelerating inflation rate of unemployment (nairu) and potential output. it uses the unobserved components model to propose a new method. the model consists of ukan law equations and philips curve. it uses unobservable key economic variable in the form of unobserved random trends in an equation system of three variables namely unemployment, gross dom...

Experts believe that by lowering the interest rate on bank accounts, total cost of goods and services decreases, and secondly, investment production increases,  both of which lead to lower inflation and provide stable employment field, on the other hand, are concerned about the negative effects of lowering the interest rate without lowering inflation and know the underlying requirement of nomin...

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...

the main idea of this paper is to study the dependence between the probability of default and the recovery rate on credit portfolio and to seek empirically this relationship. we examine the dependence between pd and rr by theoretical approach. for the empirically methodology, we use the bootstrapped quantile regression and the simultaneous quantile regression. these methods allow to determinate...

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...
