Available in PDF, EPUB and Kindle. Book excerpt: Much of the research on fiscal multipliers has used reduced form modelling approaches. While these models have been extended to include richer controls and identification approaches, it remains unclear whether shocks identified capture the true structural shocks. An alternative way to identify these shocks is through dynamic stochastic general equilibrium models. This paper estimates an open-economy dynamic stochastic general equilibrium model for South Africa, but with a more detailed fiscal block, to measure the impact of fiscal policy shocks on macroeconomic outcomes. Simulations indicate that government spending and investment multipliers are generally positive, albeit smaller than 1. Second, it is found that taxes are highly distortionary, with large negative multipliers for private consumption and investment. In contrast, the impact of tax shocks on output is ambiguous. Finally, simulations suggest that government consumption spending and labour and consumption taxes are the most effective instruments for stabilizing debt after a fiscal shock.

Available in PDF, EPUB and Kindle. Book excerpt: For a long time, economic research on Africa was not seen as a profitable venture intellectually or professionally-few researchers in top-ranked institutions around the world chose to become experts in the field. This was understandable: the reputation of Africa-centered economic research was not enhanced by the well-known limitations of economic data across the continent. Moreover, development economics itself was not always fashionable, and the broader discipline of economics has had its ups and downs, and has been undergoing a major identity crisis because it failed to predict the Great Recession. Times have changed: many leading researchers-including a few Nobel laureates-have taken the subject of Africa and economics seriously enough to devote their expertise and creativity to it. They have been amply rewarded: the richness, complexities, and subtleties of African societies, civilizations, rationalities, and ways of living, have helped renew the humanities and the social sciences-and economics in particular-to the point that the continent has become the next major intellectual frontier to researchers from around the world. In collecting some of the most authoritative statements about the science of economics and its concepts in the African context, this ^lhandbook (the first of two volumes) opens up the diverse acuity of commentary on exciting topics, and in the process challenges and stimulates the quest for knowledge. Wide-ranging in its scope, themes, language, and approaches, this volume explores, examines, and assesses economic thinking on Africa, and Africa's contribution to the discipline. The editors bring a set of powerful resources to this endeavor, most notably a team of internationally-renowned economists whose diverse viewpoints are complemented by the perspectives of philosophers, political scientists, and anthropologists.
Download or read book A Medium Scale DSGE Model for the Integrated Policy Framework written by Mr. Tobias Adrian and published by International Monetary Fund. This book was released on 2022-01-28 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper jointly analyzes the optimal conduct of monetary policy, foreign exchange intervention, fiscal policy, macroprudential policy, and capital flow management. This policy analysis is based on an estimated medium-scale dynamic stochastic general equilibrium (DSGE) model of the world economy, featuring a range of nominal and real rigidities, extensive macrofinancial linkages with endogenous risk, and diverse spillover transmission channels. In the pursuit of inflation and output stabilization objectives, it is optimal to adjust all policies in response to domestic and global financial cycle upturns and downturns when feasible—including foreign exchange intervention and capital flow management under some conditions—to widely varying degrees depending on the structural characteristics of the economy. The framework is applied empirically to four small open advanced and emerging market economies.
Download or read book Financial Crises in DSGE Models written by Mr.Jaromir Benes and published by International Monetary Fund. This book was released on 2014-04-04 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents the theoretical structure of MAPMOD, a new IMF model designed to study vulnerabilities associated with excessive credit expansions, and to support macroprudential policy analysis. In MAPMOD, bank loans create purchasing power that facilitates adjustments in the real economy. But excessively large and risky loans can impair balance sheets and sow the seeds of a financial crisis. Banks respond to losses through higher spreads and rapid credit cutbacks, with adverse effects for the real economy. These features allow the model to capture the basic facts of financial cycles. A companion paper studies the simulation properties of MAPMOD.
Download or read book Methods for Applied Macroeconomic Research written by Fabio Canova and published by Princeton University Press. This book was released on 2011-09-19 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last twenty years have witnessed tremendous advances in the mathematical, statistical, and computational tools available to applied macroeconomists. This rapidly evolving field has redefined how researchers test models and validate theories. Yet until now there has been no textbook that unites the latest methods and bridges the divide between theoretical and applied work. Fabio Canova brings together dynamic equilibrium theory, data analysis, and advanced econometric and computational methods to provide the first comprehensive set of techniques for use by academic economists as well as professional macroeconomists in banking and finance, industry, and government. This graduate-level textbook is for readers knowledgeable in modern macroeconomic theory, econometrics, and computational programming using RATS, MATLAB, or Gauss. Inevitably a modern treatment of such a complex topic requires a quantitative perspective, a solid dynamic theory background, and the development of empirical and numerical methods--which is where Canova's book differs from typical graduate textbooks in macroeconomics and econometrics. Rather than list a series of estimators and their properties, Canova starts from a class of DSGE models, finds an approximate linear representation for the decision rules, and describes methods needed to estimate their parameters, examining their fit to the data. The book is complete with numerous examples and exercises. Today's economic analysts need a strong foundation in both theory and application. Methods for Applied Macroeconomic Research offers the essential tools for the next generation of macroeconomists.
Download or read book Assessing Dsge Models with Capital Accumulation and Indeterminacy written by Mr.Vadim Khramov and published by International Monetary Fund. This book was released on 2012-03-01 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The simulated results of this paper show that New Keynesian DSGE models with capital accumulation can generate substantial persistencies in the dynamics of the main economic variables, due to the stock nature of capital. Empirical estimates on U.S. data from 1960:I to 2008:I show the response of monetary policy to inflation was almost twice lower than traditionally considered, as capital accumulation creates an additional channel of influence through real interest rates in the production sector. Versions of the model with indeterminacy empirically outperform determinate versions. This paper allows for the reconsideration of previous findings and has significant monetary policy implications.
Download or read book Bayesian Multivariate Time Series Methods for Empirical Macroeconomics written by Gary Koop and published by Now Publishers Inc. This book was released on 2010 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bayesian Multivariate Time Series Methods for Empirical Macroeconomics provides a survey of the Bayesian methods used in modern empirical macroeconomics. These models have been developed to address the fact that most questions of interest to empirical macroeconomists involve several variables and must be addressed using multivariate time series methods. Many different multivariate time series models have been used in macroeconomics, but Vector Autoregressive (VAR) models have been among the most popular. Bayesian Multivariate Time Series Methods for Empirical Macroeconomics reviews and extends the Bayesian literature on VARs, TVP-VARs and TVP-FAVARs with a focus on the practitioner. The authors go beyond simply defining each model, but specify how to use them in practice, discuss the advantages and disadvantages of each and offer tips on when and why each model can be used.

It reviews the state of the art in Bayesian econometric methodology, with chapters on posterior simulation and Markov chain Monte Carlo methods, Bayesian nonparametric techniques, and the specialized tools used by Bayesian time series econometricians such as state space models and particle filtering. It also includes chapters on Bayesian principles and methodology.
Download or read book Managing Reductions in Aid Inflows Assessing Policy Choices in Haiti written by Ioana Moldovan and published by International Monetary Fund. This book was released on 2018-09-11 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: A low-income country such as Haiti that confronts an environment of diminishing aid inflows must assess tradeoffs among the available policy options: spending cuts, monetization, sales of debt, or use of foreign reserves. To provide the analytical tools for this task, the paper draws from a set of DSGE models recently developed to evaluate policy choices in low-income countries for which external aid flows represent an important revenue source. Two simplified stylized variations of the main model are used to gain intuition and initially assess the trdeaoffs. Subsequenctly a full-scale small open economy DSGE model, calibrated to match conditions in Haiti and in similar low-income countries, is employed. Several key results are common to all model versions. While sales of foreign exchange reserves can compensate for the loss of aid inflows, this strategy is not sustainable. The remaining policy choices entail larger welfare costs, involving lower consumption levels and real depreciation. The results suggest that a mixture of spending cuts and depreciation is the best strategy, when use of foreign reserves is constrained.
Download or read book Exchange Rate Flexibility and Credit during Capital Inflow Reversals written by Mr.Nicolas E. Magud and published by International Monetary Fund. This book was released on 2014-04-16 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: We document the behavior of macro and credit variables during episodes of capital inflows reversals in economies with different degrees of exchange rate flexibility. We find that exchange rate flexibility is associated with milder credit growth during the boom but, even though smaller than in more rigid regimes, it cannot shield the economy from a credit reversal. Furthermore, we observe what we dub as a recovery puzzle: credit growth in economies with more flexible exchange rate regimes remains tepid well after the capital flow reversal takes place. This results stress the complementarity of macro-prudential policies with the exchange rate regime. More flexible regimes could help smoothing the credit cycle through capital surchages and dynamic provisioning that build buffers to counteract the credit recovery puzzle. In contrast, more rigid exchange rate regimes would benefit the most from measures to contain excessive credit growth during booms, such as reserve requirements, loan-to-income ratios, and debt-to-income and debt-service-to-income limits.

This book was released on 2021-04-30 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Morocco Policy Analysis model (MOPAM) was created in the Bank Al-Maghrib to simulate the impact of external developments, domestic macroeconomic policies, and structural reforms on key macroeconomic aggregates. We describe its structure and demonstrate its operation on two medium-term scenarios: (1) fiscal consolidation to stabilize the debt-to-GDP ratio and (2) the effects of the COVID-19 shock, including the endogenous fiscal and monetary policy response.

Download or read book News Shocks in Open Economies written by Mr.Rabah Arezki and published by International Monetary Fund. This book was released on 2015-09-29 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper explores the effect of news shocks on the current account and other macroeconomic variables using worldwide giant oil discoveries as a directly observable measure of news shocks about future output ? the delay between a discovery and production is on average 4 to 6 years. We first present a two-sector small open economy model in order to predict the responses of macroeconomic aggregates to news of an oil discovery. We then estimate the effects of giant oil discoveries on a large panel of countries. Our empirical estimates are consistent with the predictions of the model. After an oil discovery, the current account and saving rate decline for the first 5 years and then rise sharply during the ensuing years. Investment rises robustly soon after the news arrives, while GDP does not increase until after 5 years. Employment rates fall slightly for a sustained period of time.
Download or read book Debt Sustainability Public Investment and Natural Resources in Developing Countries written by Mr.Giovanni Melina and published by International Monetary Fund. This book was released on 2014-04-01 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents the DIGNAR (Debt, Investment, Growth, and Natural Resources) model, which can be used to analyze the debt sustainability and macroeconomic effects of public investment plans in resource-abundant developing countries. DIGNAR is a dynamic, stochastic model of a small open economy. It has two types of households, including poor households with no access to financial markets, and features traded and nontraded sectors as well as a natural resource sector. Public capital enters production technologies, while public investment is subject to inefficiencies and absorptive capacity constraints. The government has access to different types of debt (concessional, domestic and external commercial) and a resource fund, which can be used to finance public investment plans. The resource fund can also serve as a buffer to absorb fiscal balances for given projections of resource revenues and public investment plans. When the fund is drawn down to its minimal value, a combination of external and domestic borrowing can be used to cover the fiscal gap in the short to medium run. Fiscal adjustments through tax rates and government non-capital expenditures—which may be constrained by ceilings and floors, respectively—are then triggered to maintain debt sustainability. The paper illustrates how the model can be particularly useful to assess debt sustainability in countries that borrow against future resource revenues to scale up public investment.
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.
Download or read book Fiscal Consolidation and Public Wages written by Juin-Jen Chang and published by International Monetary Fund. This book was released on 2019-06-10 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: A New Keynesian model with government production, public compensation, and unemployment is fit to U.S. data to study the macroeconomic and fiscal effects of public wage reductions. We find that accounting for the type of government spending is crucial for its macroeconomic implications. Although reductions in public wages and government purchases of goods have similar effects on total output and the fiscal balance, the former can raise private output slightly, in contrast to the substantial contractionary effects of the latter. In addition, the baseline estimation finds that exogenous public wage reductions decrease private wages. Model counterfactuals show that sufficiently rigid nominal private wages can reverse the response of private wages, as the rigidity dampens the labor reallocation effect from the public to private sector that exerts downward pressure on private wages.
