Available in PDF, EPUB and Kindle. Book excerpt: This paper studies the equilibrium dynamics of an economy with firm selection and aggregate fluctuations. A firm has access to a noisy signal about the aggregate state and learns about its individual profitability (type) from realized revenue history. When a firm cannot separate the aggregate state and its type, transitory aggregate shocks have a persistent hangover effect on the firm's subsequent belief about its individual type. Endogenous firm selection exacerbates the aggregate impact of such shocks, and learning prolongs it. A feature of the rational-expectations competitive equilibrium is that each firm's decision hinges on its own beliefs but is independent of the endogenous cross-sectional type-belief distribution. With a tractable characterization of the equilibrium dynamics, the model provides a unified view about firm selection, endogenous volatility in uncertainty, and time-varying resource misallocation.

Download or read book An Introduction to Computational Macroeconomics written by Anelí Bongers and published by Vernon Press. This book was released on 2020-09-01 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an introduction to computational macroeconomics, using a new approach to the study of dynamic macroeconomic models. It solves a variety of models in discrete time numerically, using a Microsoft Excel spreadsheet as a computer tool. The solved models include dynamic macroeconomic models with rational expectations, both non-microfounded and microfounded, constituting a novel approach that facilitates the learning and use of dynamic general equilibrium models, which have now become the principal tool for macroeconomic analysis. Spreadsheets are widely known and relatively easy to use, meaning that the computer skills needed to work with dynamic general equilibrium models are affordable for undergraduate students in Advanced Macroeconomics courses.

Download or read book Post Walrasian Macroeconomics written by David Colander and published by Cambridge University Press. This book was released on 2006-07-17 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macroeconomics is evolving in an almost dialectic fashion. The latest evolution is the development of a new synthesis that combines insights of new classical, new Keynesian and real business cycle traditions into a dynamic, stochastic general equilibrium (DSGE) model that serves as a foundation for thinking about macro policy. That new synthesis has opened up the door to a new antithesis, which is being driven by advances in computing power and analytic techniques. This new synthesis is coalescing around developments in complexity theory, automated general to specific econometric modeling, agent-based models, and non-linear and statistical dynamical models. This book thus provides the reader with an introduction to what might be called a Post Walrasian research program that is developing as the antithesis of the Walrasian DSGE synthesis.

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 Innovation Globalization and Firm Dynamics written by Anna M. Ferragina and published by Routledge. This book was released on 2014-03-14 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the relationship between firm dynamics, innovation and globalization, the processes that are essential for long term economic growth and welfare creation. This volume deals with these three issues in three sections titled respectively: entrepreneurship, new firm formation and growth; productivity-innovation-growthnexus; globalization, multinational firms and producers’ dynamics. The book presents new studies written by distinguished researchers in the field, who use state-of-the-art methodologies and extensive sources of firm- and plant-level longitudinal data to analyze and understand these major economic issues facing modern economies. In the first section, the book proposes two comprehensive introductory surveys which explore in detail the underpinnings of entrepreneurship, new firm formation and growth in advanced and developing countries. The second fundamental issue, productivity-innovation and firm dynamics, is approached by examining key drivers of selection mechanisms such as size, scale elasticity, innovative efforts, financial fragility of the firms, barriers to entry and exit, capital and financial market distortions, institutional inefficiencies and other market imperfections which affect the ability of firms to expand or enter. The third section examines differences, linkages and intertwined evolution of foreign and domestic firms in their dynamics of survival and growth in different institutional contexts and periods. Each chapter includes a detailed discussion of the implications of the respective analyses for enterprise policy. In a concluding chapter the overall implications for enterprise policy of the analyses presented in the different chapters are drawn by the Editors. This approach ensures that the book is integrated around a coherent central theme in comprehensive framework. The book responds to a growing concern among scholars, professionals, and policy makers over the recent decades about firm ability to survive and compete in a context of increasing globalization and international competition. The approach adopted is both theoretical and empirical with consideration of paradigmatic case studies in Europe, Africa and Asia, providing new evidence on developed, developing and transition economies in a comparative perspective. The cases selected represent different levels of development, different firms strategies and paths, with distinct outcomes. The book is an essential reading for scholars and students concerned with industry development, public policy and globalization, as well as to all those involved professionally in such issues.

Download or read book Dynamic General Equilibrium Modeling written by Burkhard Heer and published by Springer Science & Business Media. This book was released on 2009-08-12 with total page 720 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 Optimal Unemployment Insurance written by Andreas Pollak and published by Mohr Siebeck. This book was released on 2007 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Designing a good unemployment insurance scheme is a delicate matter. In a system with no or little insurance, households may be subject to a high income risk, whereas excessively generous unemployment insurance systems are known to lead to high unemployment rates and are costly both from a fiscal perspective and for society as a whole. Andreas Pollak investigates what an optimal unemployment insurance system would look like, i.e. a system that constitutes the best possible compromise between income security and incentives to work. Using theoretical economic models and complex numerical simulations, he studies the effects of benefit levels and payment durations on unemployment and welfare. As the models allow for considerable heterogeneity of households, including a history-dependent labor productivity, it is possible to analyze how certain policies affect individuals in a specific age, wealth or skill group. The most important aspect of an unemployment insurance system turns out to be the benefits paid to the long-term unemployed. If this parameter is chosen too high, a large number of households may get caught in a long spell of unemployment with little chance of finding work again. Based on the predictions in these models, the so-called "Hartz IV" labor market reform recently adopted in Germany should have highly favorable effects on the unemployment rates and welfare in the long run.

Download or read book International Financial Integration written by Mr.Gian Milesi-Ferretti and published by International Monetary Fund. This book was released on 2003-04-01 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent decades, the foreign assets and liabilities of advanced economies have grown rapidly relative to GDP, with the increase in gross cross-holdings far exceeding changes in the size of net positions. Moreover, the portfolio equity and FDI categories have grown in importance relative to international debt stocks. This paper describes the broad trends in international financial integration for a sample of industrial countries and seeks to explain the cross-country and time-series variation in the size of international balance sheets. It also examines the behavior of the rates of return on foreign assets and liabilities, relating them to "market" returns.

Download or read book Hysteresis and Business Cycles written by Ms.Valerie Cerra and published by International Monetary Fund. This book was released on 2020-05-29 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, economic growth and business cycles have been treated independently. However, the dependence of GDP levels on its history of shocks, what economists refer to as “hysteresis,” argues for unifying the analysis of growth and cycles. In this paper, we review the recent empirical and theoretical literature that motivate this paradigm shift. The renewed interest in hysteresis has been sparked by the persistence of the Global Financial Crisis and fears of a slow recovery from the Covid-19 crisis. The findings of the recent literature have far-reaching conceptual and policy implications. In recessions, monetary and fiscal policies need to be more active to avoid the permanent scars of a downturn. And in good times, running a high-pressure economy could have permanent positive effects.
