Available in PDF, EPUB and Kindle. Book excerpt: "This paper estimates the parameters of a stylized dynamic stochastic general equilibrium model using maximum likelihood and Bayesian methods, paying special attention to the issue of weak parameter identification. Given the model and the available data, the posterior estimates of the weakly identified parameters are very sensitive to the choice of priors. We provide a set of tools to diagnose weak identification, which include surface plots of the log-likelihood as a function of two parameters, heat plots of the log-likelihood as a function of three parameters, Monte Carlo simulations using artificial data, and Bayesian estimation using three sets of priors. We find that the policy coefficients and the parameter governing the elasticity of labor supply are weakly identified by the data, and posterior predictive distributions remind us that DSGE models may make poor forecasts even when they fit the data well. Although parameter identification is model- and data-specific, the lack of identification of some key structural parameters in a small-scale DSGE model such as the one we examine should raise a red flag to researchers trying to estimate--and draw valid inferences from--large-scale models featuring many more parameters"--Federal Reserve Board web site.

This book was released on 2005-03 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper develops a small open economy model where entrepreneurs partially finance investment using foreign currency denominated debt subject to a risk premium above and beyond international interest rates. We use Bayesian estimation techniques to evaluate the importance of balance sheet vulnerabilities combined with the presence of the financial accelerator for emerging market countries. Using Korean data, we obtain an estimate for the external risk premium, indicating the importance of the financial accelerator and potential balance sheet vulnerabilities for macroeconomic fluctuations. Furthermore, our estimates of the Taylor rule imply a strong preference to smooth both exchange rate and interest rate fluctuations.

Book excerpt: Examining the business cycle and the monetary transmission mechanism in a small open economy based on the macroeconomic models is vital for successfully implementing forward-looking and counter-cyclical macroeconomic policies. In the context, this thesis focuses on the importance of various modelling implications (i.e., frictions and shocks) in developing empirically viable small open economy dynamic stochastic general equilibrium (DSGE) models. The thesis comprises three self-contained chapters on formulating, estimating and evaluating the DSGE models using Bayesian methods and data for Australia and the United States (US) (or G7 for Chapter 2), as well as a general thesis introduction and conclusion. Chapter 2 investigates the quantitative role of a cost channel of monetary policy and an uncovered interest rate parity (UIP) modification in an estimated small open economy DSGE model. For this purpose, a small open economy New Keynesian DSGE model developed by Justiniano and Preston (2010a) (i.e., benchmark model for the thesis) is augmented to incorporate the cost channel and the UIP modification based on a forward premium puzzle. The empirical analysis shows that introducing the cost channel and the UIP modification into the estimated model improves its ability to fit business cycle properties of key macroeconomic variables and to account for the empirical evidence on the monetary transmission mechanism. Chapter 3 assesses the importance of news shocks in a small open economy DSGE model for analysing business cycle properties of macroeconomic aggregates, including labour market variables. To this end, the model in Chapter 2 is enlarged in Chapter 3 to include (i) the theory of invoulntary unemployment proposed by Galí (2011), (ii) an endogenous preference shifter, similar to that used by Galí et al. (2011), and (iii) both news (anticipated) and unanticipated components in each structural shock. The results show that the estimated model is able to qualitatively replicate the existing VAR-based results (e.g., Kosaka 2013, Kamber et al. 2014 and Theodoridis and Zanetti 2014) on news driven business cycles, and the presence of news shocks has the potential to improve the model fit. Another important finding is that news shocks have been the main drivers of the Australian business cycle in the inflation-targeting period. Chapter 4 examines the significance of financial frictions and shocks in a small open economy DSGE model for explaining macroeconomic fluctuations. In doing so, Chapter 4 has further extended the model in Chapter 3 to a rich DSGE model in the two-country setting with involuntary unemployment, financial frictions and shocks. The main results include (i) the presence of financial accelerator improves the model fit, (ii) the financial accelerator amplifies and propagates the effects of monetary policy shocks on output, but dampens the effects of technology and labour supply shocks in Australia and the US, and (iii) financial shocks (i.e., shocks to the credit spread) are important for explaining investment and output fluctuations in both countries. Finally, this thesis provides implications for designing macroeconomic policies and building empirically viable open economy DSGE models to analyse the transmission mechanism of monetary policy and the business cycle.

Available in PDF, EPUB and Kindle. Book excerpt: Dynamic stochastic general equilibrium (DSGE) models have become one of the workhorses of modern macroeconomics and are extensively used for academic research as well as forecasting and policy analysis at central banks. This book introduces readers to state-of-the-art computational techniques used in the Bayesian analysis of DSGE models. The book covers Markov chain Monte Carlo techniques for linearized DSGE models, novel sequential Monte Carlo methods that can be used for parameter inference, and the estimation of nonlinear DSGE models based on particle filter approximations of the likelihood function. The theoretical foundations of the algorithms are discussed in depth, and detailed empirical applications and numerical illustrations are provided. The book also gives invaluable advice on how to tailor these algorithms to specific applications and assess the accuracy and reliability of the computations. Bayesian Estimation of DSGE Models is essential reading for graduate students, academic researchers, and practitioners at policy institutions.

This book was released on 2010-08 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thesis (M.A.) from the year 2010 in the subject Business economics - Banking, Stock Exchanges, Insurance, Accounting, grade: A-, Central European University Budapest, language: English, abstract: Using of developments of the last decade in Bayesian estimation, I estimate a small open economy Dynamic Stochastic General Equ ilibr ium (DSGE) model fo r Turkey. The thesis explicitly accounts for a monetar y regime change fro m an exchange rate targeting to an exp licit inflation targeting with a flexible exchange rate. In both regimes, I investigate the behavior of the monetary authority and the main driving forces of business cycles of key macro economy variables of the Turkish economy. My results can be summarized as follows. Monetary policy focused on the stabilizing of the nominal exchange rate in the exchange rate targeting regime. But, it is mainly concerned with the price stability in the inflation targeting reg ime. Monetary policy shocks were the main sources of the fluctuations under both regimes. However, the foreign output shock in the first regime and the real exchange rate shock in the second regime appeared as the additional sources of the fluctuations in the business cycles. The Central Bank of Tur key managed to neutralize inflatio nary sho cks and achieved stability in output and consumption after the regime change. Keywords: Turkey, Bayesian estimation, DSGE models, regime change

Available in PDF, EPUB and Kindle. Book excerpt: We propose a methodology to take dynamic stochastic general equilibrium (DSGE) models to the data based on the combination of differentiable state-space models and the Hamiltonian Monte Carlo (HMC) sampler. First, we introduce a method for implicit automatic differentiation of perturbation solutions of DSGE models with respect to the model's parameters. We can use the resulting output for various tasks requiring gradients, such as building an HMC sampler, to estimate first- and second-order approximations of DSGE models. The availability of derivatives also enables a general filter-free method to estimate nonlinear, non-Gaussian DSGE models by sampling the joint likelihood of parameters and latent states. We show that the gradient-based joint likelihood sampling approach is superior in efficiency and robustness to standard Metropolis-Hastings samplers by estimating a canonical real business cycle model, a real small open economy model, and a medium-scale New Keynesian DSGE model.

This book was released on 2023-06-30 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: We estimate a New Keynesian small open economy model which allows for foreign exchange (FX) market frictions and a potential role for FX interventions for a large set of emerging market economies (EMEs) and some inflation targeting (IT) advanced economy (AE) countries serving as a control group. Next, we use the estimated model to examine the empirical support for the view that interest rate policy may not be sufficient to stabilize output and inflation following capital outflow shocks, and the extent to which FX interventions (FXI) can improve policy tradeoffs. Our results reveal significant structural differences between AEs and EMEs—in particular FX market depth—leading to different transmission of capital outflow shocks which justifies occasional use of FXI in some EMEs in certain situations. Our analysis also highlights the critical importance of accounting for the endogeneity of FXI behavior when assessing FX market depth and policy tradeoffs associated with volatile capital flows in past episodes.

Download or read book Overview of the New Calibrated DSGE Model of the Economy of North Macedonia written by Tibor Hlédik and published by International Monetary Fund. This book was released on 2024-08-30 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a calibrated DSGE model of the economy of North Macedonia that was developed at the National Bank of the Republic of North Macedonia (NBRNM) within a technical assistance project delivered jointly by the International Monetary Fund (IMF) and the Czech National Bank (CNB). The model structure reflects the specific characteristics of the economy of North Macedonia. Namely, it is a small open economy DSGE model featuring a fixed exchange rate regime functioning in an economy experiencing structural changes over time. The paper provides a detailed overview of the theoretical structure of the model, including optimization problems of economic agents and first-order optimality conditions. A particular emphasis is put on model calibration, as well as on model evaluation, including the analysis of impulse responses, shock decompositions and historical in-sample simulation. Compared to other empirical papers focusing on DSGE models, our approach explicitly includes additional trends and wedges needed to capture non-stationary great ratios as well as the Balassa-Samuelson effect. The model has been developed to complement the existing analytic tools used at the NBRNM for policy analyses and to improve the understanding of the underlying drivers of the business cycle of the domestic economy.

Available in PDF, EPUB and Kindle. Book excerpt: United States monetary policy has traditionally been modeled under the assumption that the domestic economy is immune to international factors and exogenous shocks. Such an assumption is increasingly unrealistic in the age of integrated capital markets, tightened links between national economies, and reduced trading costs. International Dimensions of Monetary Policy brings together fresh research to address the repercussions of the continuing evolution toward globalization for the conduct of monetary policy. In this comprehensive book, the authors examine the real and potential effects of increased openness and exposure to international economic dynamics from a variety of perspectives. Their findings reveal that central banks continue to influence decisively domestic economic outcomes—even inflation—suggesting that international factors may have a limited role in national performance. International Dimensions of Monetary Policy will lead the way in analyzing monetary policy measures in complex economies.

This book was released on 2011-09-01 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: When estimating DSGE models, the number of observable economic variables is usually kept small, and it is conveniently assumed that DSGE model variables are perfectly measured by a single data series. Building upon Boivin and Giannoni (2006), we relax these two assumptions and estimate a fairly simple monetary DSGE model on a richer data set. Using post-1983 U.S.data on real output, inflation, nominal interest rates, measures of inverse money velocity, and a large panel of informational series, we compare the data-rich DSGE model with the regular - few observables, perfect measurement - DSGE model in terms of deep parameter estimates, propagation of monetary policy and technology shocks and sources of business cycle fluctuations. We document that the data-rich DSGE model generates a higher implied duration of Calvo price contracts and a lower slope of the New Keynesian Phillips curve. To reduce the computational costs of the likelihood-based estimation, we employed a novel speedup as in Jungbacker and Koopman (2008) and achieved the time savings of 60 percent.
