طبیعت متغیر با زمان و عوامل تعیین کننده گذرگاه نرخ ارز اقتصاد کلان

The objectives of this study are two-fold: i) to derive time-varying exchange rate pass-through (ERPT) degree and ii) investigate the macroeconomic determinants of the degree of ERPT. For this purpose, the study adopts a distinct methodology combining Dynamic Conditional Correlation-Generalized Autoregressive Conditional Heteroskedasticity (DCC-GARCH) and panel threshold regression analyses. The data from a large sample of countries are used and time-varying ERPT measure is obtained with an application of DCC-GARCH to each country in the sample. Then the macroeconomic determinants of ERPT are examined by making use of both cross country and time variations in a panel regression model. The time varying structure of ERPT clearly shows that the ERPT degree has been low over the last three decades and declining dramatically since mid-1990s. Further, ERPT responds positively to average inflation and inflation rate volatility while negatively to exchange rate volatility, the degree of openness and output gap.
