Mathematics for Stability and Optimization of Economic Systems


Book Description

Economic Theory and Mathematical Economics: Mathematics for Stability and Optimization of Economic Systems provides information pertinent to the stability aspects and optimization methods relevant to various economic systems. This book presents relevant mathematical theorems sufficient to develop important economic systems, including Leontief input–output systems, Keynesian dynamic models, the Ramsey optimal accumulation systems, and von Neumann expanding economic systems. Organized into two parts encompassing nine chapters, this book begins with an overview of useful theorems on matrices, eigenvalue problems, and matrices with dominant diagonals and P-matrices. This text then explores the linear transformations on vector spaces. Other chapters consider the Hawkins–Simon theorem concerning non-negative linear systems. This book discusses as well the dual linear relations and optimization methods applicable to inequality economic systems. The final chapter deals with powerful optimal control method for dynamical systems. This book is a valuable resource for mathematicians, economists, research workers, and graduate students.




Inflation in Emerging and Developing Economies


Book Description

This is the first comprehensive study in the context of EMDEs that covers, in one consistent framework, the evolution and global and domestic drivers of inflation, the role of expectations, exchange rate pass-through and policy implications. In addition, the report analyzes inflation and monetary policy related challenges in LICs. The report documents three major findings: In First, EMDE disinflation over the past four decades was to a significant degree a result of favorable external developments, pointing to the risk of rising EMDE inflation if global inflation were to increase. In particular, the decline in EMDE inflation has been supported by broad-based global disinflation amid rapid international trade and financial integration and the disruption caused by the global financial crisis. While domestic factors continue to be the main drivers of short-term movements in EMDE inflation, the role of global factors has risen by one-half between the 1970s and the 2000s. On average, global shocks, especially oil price swings and global demand shocks have accounted for more than one-quarter of domestic inflation variatio--and more in countries with stronger global linkages and greater reliance on commodity imports. In LICs, global food and energy price shocks accounted for another 12 percent of core inflation variatio--half more than in advanced economies and one-fifth more than in non-LIC EMDEs. Second, inflation expectations continue to be less well-anchored in EMDEs than in advanced economies, although a move to inflation targeting and better fiscal frameworks has helped strengthen monetary policy credibility. Lower monetary policy credibility and exchange rate flexibility have also been associated with higher pass-through of exchange rate shocks into domestic inflation in the event of global shocks, which have accounted for half of EMDE exchange rate variation. Third, in part because of poorly anchored inflation expectations, the transmission of global commodity price shocks to domestic LIC inflation (combined with unintended consequences of other government policies) can have material implications for poverty: the global food price spikes in 2010-11 tipped roughly 8 million people into poverty.




Exchange Rate Misalignment in Developing Countries


Book Description

This article analyzes the theory of equilibrium real exchange rates and defines misalignment as a deviation of the real exchange rate (RER) from its equilibrium level. The role of macroeconomic policies is then analyzed under three alternative nominal exchange rate regimes: predetermined nominal exchange rates; floating nominal rates; and dual or black market nominal exchange rates. This discussion points out how inconsistent macroeconomic policies often lead to real exchange rate misalignment. Corrective measures, including nominal devaluation and several alternative approaches, are then evaluated.




Multiple Exchange Rates, Fiscal Deficits and Inflation Dynamics


Book Description

The paper explores the inflationary implications of exchange rate regime reforms in a small open economy model combining the public finance view of inflation with multiple exchange markets. To account for the experience of many developing countries, the analysis focuses on transitions to multiple official exchange markets. In those countries, multiple exchange rates were often announced as temporary. The paper shows that the dynamic response of inflation to the reform markedly differ whether the announcement is credible or not. The paper also compares the response of inflation under a fixed crawl of nominal official rates and under the presence of policy rules aimed at reducing the spread between the official and parallel exchange rates.




IMF Staff papers


Book Description

This paper reviews an attempt that is made to arrive at a rough quantification of the possible effects of various techniques of IMF reserve creation through the IMF on its own liquidity. For purposes of comparison, the additional needs for IMF resources arising, respectively, from the several techniques of reserve creation are expressed in terms of the amounts of the currencies that are normally suitable for drawing, distributed in proportion to quota, to which the IMF would have to secure to cover the additional needs in question. When reserves are created by the IMF, their creation will in some instances involve a use of Fund resources and may affect its own liquidity. When account is taken of the secondary impact of gold investment on world reserves, it appears that the liquidity cost to the IMF of creating reserves by means of gold investment, though greater per unit of investment, might be somewhat less per unit of reserves created than that of other forms of investment.




A Monetary and Fiscal History of Latin America, 1960–2017


Book Description

A major, new, and comprehensive look at six decades of macroeconomic policies across the region What went wrong with the economic development of Latin America over the past half-century? Along with periods of poor economic performance, the region’s countries have been plagued by a wide variety of economic crises. This major new work brings together dozens of leading economists to explore the economic performance of the ten largest countries in South America and of Mexico. Together they advance the fundamental hypothesis that, despite different manifestations, these crises all have been the result of poorly designed or poorly implemented fiscal and monetary policies. Each country is treated in its own section of the book, with a lead chapter presenting a comprehensive database of the country’s fiscal, monetary, and economic data from 1960 to 2017. The chapters are drawn from one-day academic conferences—hosted in all but one case, in the focus country—with participants including noted economists and former leading policy makers. Cowritten with Nobel Prize winner Thomas J. Sargent, the editors’ introduction provides a conceptual framework for analyzing fiscal and monetary policy in countries around the world, particularly those less developed. A final chapter draws conclusions and suggests directions for further research. A vital resource for advanced undergraduate and graduate students of economics and for economic researchers and policy makers, A Monetary and Fiscal History of Latin America, 1960–2017 goes further than any book in stressing both the singularities and the similarities of the economic histories of Latin America’s largest countries.

Fiscal Deficits and Inflation


Book Description

Macroeconomic theory postulates that fiscal deficits cause inflation. Yet empirical research has had limited success in uncovering this relationship. This paper reexamines the issue in light of broader data and a new modeling approach that incorporates two key features of the theory. Unlike previous studies, we model inflation as nonlinearly related to fiscal deficits through the inflation tax base and estimate this relationship as intrinsically dynamic, using panel techniques that explicitly distinguish between short- and long-run effects of fiscal deficits. Results spanning 107 countries over 1960-2001 show a strong positive association between deficits and inflation among high-inflation and developing country groups, but not among low-inflation advanced economies.




Coordination of Monetary and Fiscal Policies


Book Description

Recently, monetary authorities have increasingly focused on implementing policies to ensure price stability and strengthen central bank independence. Simultaneously, in the fiscal area, market development has allowed public debt managers to focus more on cost minimization. This “divorce” of monetary and debt management functions in no way lessens the need for effective coordination of monetary and fiscal policy if overall economic performance is to be optimized and maintained in the long term. This paper analyzes these issues based on a review of the relevant literature and of country experiences from an institutional and operational perspective.




Exchange Rate Economics


Book Description

''In summary, the book is valuable as a textbook both at the advanced undergraduate level and at the graduate level. It is also very useful for the economist who wants to be brought up-to-date on theoretical and empirical research on exchange rate behaviour.'' ""Journal of International Economics""




Evolving Monetary Policy Frameworks in Low-Income and Other Developing Countries


Book Description

Over the past two decades, many low- and lower-middle income countries (LLMICs) have improved control over fiscal policy, liberalized and deepened financial markets, and stabilized inflation at moderate levels. Monetary policy frameworks that have helped achieve these ends are being challenged by continued financial development and increased exposure to global capital markets. Many policymakers aspire to move beyond the basics of stability to implement monetary policy frameworks that better anchor inflation and promote macroeconomic stability and growth. Many of these LLMICs are thus considering and implementing improvements to their monetary policy frameworks. The recent successes of some LLMICs and the experiences of emerging and advanced economies, both early in their policy modernization process and following the global financial crisis, are valuable in identifying desirable features of such frameworks. This paper draws on those lessons to provide guidance on key elements of effective monetary policy frameworks for LLMICs.
