This book was released on 2001 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper derives a second-order approximation to the solution of a general class of discrete- time rational expectations models. The main theoretical contribution of the paper is to show that for any model belonging to the general class considered, the coefficients on the terms linear and quadratic in the state vector in a second-order expansion of the decision rule are independent of the volatility of the exogenous shocks. In other words, these coefficients must be the same in the stochastic and the deterministic versions of the model. Thus, up to second order, the presence of uncertainty affects only the constant term of the decision rules. In addition, the paper presents a set of MATLAB programs designed to compute the coefficients of the second-order approximation. The validity and applicability of the proposed method is illustrated by solving the dynamics of a number of model economies.

Download or read book Dynamic General Equilibrium Modeling written by Burkhard Heer and published by Springer Science & Business Media. This book was released on 2009-02-03 with total page 721 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern business cycle theory and growth theory uses stochastic dynamic general equilibrium models. In order to solve these models, economists need to use many mathematical tools. This book presents various methods in order to compute the dynamics of general equilibrium models. In part I, the representative-agent stochastic growth model is solved with the help of value function iteration, linear and linear quadratic approximation methods, parameterised expectations and projection methods. In order to apply these methods, fundamentals from numerical analysis are reviewed in detail. In particular, the book discusses issues that are often neglected in existing work on computational methods, e.g. how to find a good initial value. In part II, the authors discuss methods in order to solve heterogeneous-agent economies. In such economies, the distribution of the individual state variables is endogenous. This part of the book also serves as an introduction to the modern theory of distribution economics. Applications include the dynamics of the income distribution over the business cycle or the overlapping-generations model. In an accompanying home page to this book, computer codes to all applications can be downloaded.

Download or read book Bayesian Estimation of DSGE Models written by Edward P. Herbst and published by Princeton University Press. This book was released on 2015-12-29 with total page 295 pages. 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.

Download or read book Macroprudential Policy Incomplete Information and Inequality written by Margarita Rubio and published by International Monetary Fund. This book was released on 2017-03-22 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, we use a DSGE model to study the passive and time-varying implementation of macroprudential policy when policymakers have noisy and lagged data, as commonly observed in lowincome and developing countries (LIDCs). The model features an economy with two agents; households and entrepreneurs. Entrepreneurs are the borrowers in this economy and need capital as collateral to obtain loans. The macroprudential regulator uses the collateral requirement as the policy instrument. In this set-up, we compare policy performances of permanently increasing the collateral requirement (passive policy) versus a time-varying (active) policy which responds to credit developments. Results show that with perfect and timely information, an active approach is welfare superior, since it is more effective in providing financial stability with no long-run output cost. If the policymaker is not able to observe the economic conditions perfectly or observe with a lag, a cautious (less aggressive) policy or even a passive approach may be preferred. However, the latter comes at the expense of increasing inequality and a long-run output cost. The results therefore point to the need for a more careful consideration toward the passive policy, which is usually advocated for LIDCs.

Available in PDF, EPUB and Kindle. Book excerpt: The large swings in world food prices in recent years renew interest in the question of how monetary policy in small open economies should react to such imported price shocks. We examine this issue in a canonical open economy setting with sticky prices and where food plays a distinctive role in utility. We show how world food price shocks affect natural output and other aggregates, and derive a second order approximation to welfare. Numerical calibrations show broad CPI targeting to be welfare-superior to alternative policy rules once the variance of food price shocks is sufficiently large as in real world data.

Download or read book Optimal Fiscal Spending and Reserve Accumulation Policies under Volatile Aid written by Ioana Moldovan and published by International Monetary Fund. This book was released on 2019-06-11 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper assesses the optimal setting of fiscal spending and foreign exchange rate intervention policies in response to volatile foreign aid, in a small open economy model that incorporates typical features of low-income countries. Within a class of policy rules, it jointly considers the optimal aid spending and international reserve accumulation policies. The results show that it is optimal to adjust government spending gradually in response to unpredictable fluctuations in aid, while partially accumulating foreign exchange reserves to offset Dutch disease effects. Also, allocating relatively more of the government spending to productive public investment, and less to government consumption, is welfare improving.

Download or read book Theoretical Foundations of Macroeconomic Policy written by Giovanni Di Bartolomeo and published by Routledge. This book was released on 2016-07-15 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent economic events driven by the great financial crisis of 2007-08 has challenged some "dogma", highlighting various limits and drawbacks of current paradigms. The crisis showed the limitations of monetary policy and led to a revaluation of what levels of public debt can be considered safe. This volume aims to refresh the debate on some important long-run macroeconomic issues from new and fresh perspectives. Theoretical Foundations of Macroeconomic Policy raises a number of questions relating to the challenges faced by macroeconomic theory and policies. The common line is the long run and policy perspective. The first part of the book is devoted to the theory of growth and productivity. The second part concentrates on long-run effects of fiscal and monetary policy. Specifically, topics investigated by the international range of authors are the theory of optimal growth, the productivity policies and production function estimations, demand- vs. supply- driven growth, optimal debt default and the incompleteness of financial markets, the long-run optimal inflation target and its relationship with public finance, the long term effects of government budget constraints on growth, and effect on optimal policies in non-market clearing environment. The book will be of interest to postgraduates, researchers, and academics studying macroeconomics and fiscal policies.
