Getting Into the Nitty-Gritty of Fiscal Multipliers: Small Details, Big Impacts


Book Description

Despite the remarkable progress the literature has made throughout the past years in studying fiscal multipliers, estimates still vary considerably across studies. Partly, estimates differ because of context-specific variables that affect multipliers, but also because of the lack of a standardized framework to calculate and report them, making comparisons among studies hard to make. In this paper, we use a large panel of countries to study how some important methodological details affect the empirical estimates. Focusing on emerging economies, we show how slight changes in the filtering approach of fiscal forecast errors or the accumulation procedure of responses can significantly impact estimates. We emphasize that one of the most important features of estimating multipliers is the endogenous dynamic responses of fiscal variables to fiscal shocks, and therefore we argue against reporting multipliers as simply the output response to exogenous fiscal innovations. Although our baseline results are in line with the previous studies, our standardized framework allow us to make fairer comparisons of multiplier estimates across budgetary items and country income groups.




Estimating Fiscal Multipliers Under Alternative Exchange Rate Regimes: The Case of Bolivia


Book Description

Empirical (employing the Blanchard-Perotti framework) and modeling (using a country-specific DSGE model) approaches are used to estimate fiscal multipliers by policy instrument for Bolivia, to evaluate possible adjustments in a fiscal consolidation strategy. Multipliers are also estimated using alternative assumptions about the accompanying exchange rate regime and capital mobility, highlighting the importance of the policy mix in determining the impact of fiscal adjustments. The study exploits the DSGE modeling structure to assess this interaction of fiscal and monetary policy in a lower middle-income country under different exchange rate regimes. It finds that expenditure multipliers fall into the range of 1/3 to 2/3, with public investment multipliers slightly higher than government consumption multipliers over longer horizons, and multipliers generally higher under a peg than inflation targeting. Tax multipliers are shown to be about half of expenditure multipliers.

The Information Revolution and National Security


Book Description

The effects of the information revolution are particularly profound in the realm of national security strategy. They are creating new opportunities for those who master them. The U.S. military, for instance, is exploring ways to seize information superiority during conflicts and thus gain decisive advantages over its opponents. But the information revolution also creates new security threats and vulnerabilities. No nation has made more effective use of the information revolution than the United States, but none is more dependent on information technology. To protect American security, then, military leaders and defense policymakers must understand the information revolution. The essays in this volume are intended to contribute to such an understanding. They grew from a December 1999 conference co-sponsored by the U.S. Army War College Strategic Studies Institute and the University of Pittsburgh Matthew B. Ridgway Center for International Security Studies. The conference brought together some of the foremost members of the academic strategic studies community with representatives of the U.S. Government and U.S. military. As could be expected when examining a topic as complex as the relationship between the information revolution and national security, the presentations and discussions were far-ranging, covering such issues as the global implications of the information revolution, the need for a national information security strategy, and the role of information in U.S. military operations. While many more questions emerged than answers, the conference did suggest some vital tasks that military leaders and defense policymakers must undertake.

Renminbi Internationalization


Book Description

A Brookings Institution Press and Asian Development Bank Institute publication Meet the next global currency: the Chinese renminbi, or the "redback." Following the global financial crisis of 2008, China's major monetary policy objective is the internationalization of the renminbi, that is, to create an inter-national role for its currency akin to the international role currently played by the U.S. dollar. Renminbi internationalization is a hot topic, for good reason. It is, essentially, a window onto the Chinese government's aspirations and the larger process of economic and financial transformation. Making the renminbi a global currency requires rebalancing the Chinese economy, developing the country's financial markets and opening them to the rest of the world, and moving to a more flexible exchange rate. In other words, the internationalization of the renminbi is a monetary and financial issue with much broader supra-monetary and financial implications. This book offers a new perspective on the larger issues of economic, financial, and institutional change in what will eventually be the world's largest economy.




Big Farms Make Big Flu


Book Description

The first collection to explore infectious disease, agriculture, economics, and the nature of science together Thanks to breakthroughs in production and food science, agribusiness has been able to devise new ways to grow more food and get it more places more quickly. There is no shortage of news items on hundreds of thousands of hybrid poultry—each animal genetically identical to the next—packed together in megabarns, grown out in a matter of months, then slaughtered, processed and shipped to the other side of the globe. Less well known are the deadly pathogens mutating in, and emerging out of, these specialized agro-environments. In fact, many of the most dangerous new diseases in humans can be traced back to such food systems, among them Campylobacter, Nipah virus, Q fever, hepatitis E, and a variety of novel influenza variants. Agribusiness has known for decades that packing thousands of birds or livestock together results in a monoculture that selects for such disease. But market economics doesn't punish the companies for growing Big Flu—it punishes animals, the environment, consumers, and contract farmers. Alongside growing profits, diseases are permitted to emerge, evolve, and spread with little check. “That is,” writes evolutionary biologist Rob Wallace, “it pays to produce a pathogen that could kill a billion people.” In Big Farms Make Big Flu, a collection of dispatches by turns harrowing and thought-provoking, Wallace tracks the ways influenza and other pathogens emerge from an agriculture controlled by multinational corporations. Wallace details, with a precise and radical wit, the latest in the science of agricultural epidemiology, while at the same time juxtaposing ghastly phenomena such as attempts at producing featherless chickens, microbial time travel, and neoliberal Ebola. Wallace also offers sensible alternatives to lethal agribusiness. Some, such as farming cooperatives, integrated pathogen management, and mixed crop-livestock systems, are already in practice off the agribusiness grid. While many books cover facets of food or outbreaks, Wallace's collection appears the first to explore infectious disease, agriculture, economics and the nature of science together. Big Farms Make Big Flu integrates the political economies of disease and science to derive a new understanding of the evolution of infections. Highly capitalized agriculture may be farming pathogens as much as chickens or corn.

Post Walrasian Macroeconomics


Book Description

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.
