حذف نظام چند نرخی ارز، کاهش نوسانهای نرخ ارز، تقویت رقابتپذیری در بنگاهها و بخشهای اقتصادی و بهبود ارائهی خدمات ارزی از جمله سیاستهای ارزی است که برای تعدیل اثرهای منفی رکود تورمی میتواند مؤثر واقع شود. همچنین افزایش صادرات غیرنفتی به عنوان محرک تولید و رونق کسب وکار هم در کانون توجه سیاست گذاران اقتصادی قرار میگیرد. هدف این مقاله بررسی کارآمدی سیاستهای ارزی و تجاری مناسب برای خروج از ...
In Structural Vector Autoregressive (SVAR) models, heteroskedasticity can be exploited to identify structural parameters statistically. In this paper, we propose to capture time variation in the second moment of structural shocks by a stochastic volatility (SV) model, assuming that their log variances follow latent AR(1) processes. Estimation is performed by Gaussian Maximum Likelihood and an e...
Identifiability of Non-Gaussian Structural VAR Models for Subsampled and Mixed Frequency Time Series
Causal inference in multivariate time series is confounded by subsampling in time between the true causal scale and the observed data sampling rate. In practice, this presents challenges for inferring causal interaction between time series due to differences in sampling rates across time series and generally low sampling rates due to technological limitations. To determine instantaneous and lag...
We identify structural vector autoregressive (SVAR) models by combining sign restrictions with information in external instruments and proxy variables. We incorporate the proxy variables by augmenting the SVAR with equations that relate them to the structural shocks. Our modeling framework allows to simultaneously identify different shocks using either sign restrictions or an external instrumen...
The author evaluates the ability of a variety of output-gap estimators to accurately measure the output gap in a model economy. A small estimated model of the Canadian economy is used to generate artificial data. Using output and inflation data generated by this model, the author uses each output-gap estimation methodology to construct an estimate of the true output gap. He then evaluates the m...
In this paper we apply the method of inferred causation for macroeconomic analysis. First we introduce briefly the theory of inferred causation developed by Pearl and Verma (1991). We apply this method to the identification of structural vector autoregression (SVAR) models. In an example of monetary policy analysis we demonstrate how causal information embedded in the data can be used to identi...
This paper investigates changes in the conduct of U.S. monetary policy. Monetary policy is modeled in the context of the Bernanke-Mihov (1998) structural VAR (SVAR) extended to allow explicitly for the Fed’s forward looking behavior. This is achieved by including its realtime forecasts on in‡ation and unemployment (the “Greenbook” forecasts). Stability tests that exploit the SVAR identifying re...
