A Consistency Framework for Macroeconomic Analysis


Book Description

Illustrating with data for Colombia and Zimbabwe, Easterly presents a consistency framework useful for checking projections or constructing macroeconomic models, reconciling separate accounts for the government, monetary system, nonfinancial private sector, balance of payments, and national accounts.




Framework for Macroeconomic Analysis


Book Description

Models of the RMSM-X genre can-- while preserving their logical structure-- incorporate behavioral equations and provide useful insights into policy actions that would correct internal and external macroeconomic imbalances.




Dynamic Macroeconomics


Book Description

An attempt to revitalize the traditions of nonmarket clearing approaches to macroeconomics. Using tools from dynamic analysis, the text introduces a consistent, integrated framework for disequilibrium macroeconomic dynamics and explore its relationship to the competing equilibrium dynamics.




Macroeconomic Analysis


Book Description

A concise but rigorous and thorough introduction to modern macroeconomic theory. This book offers an introduction to modern macroeconomic theory. It is concise but rigorous and broad, covering all major areas in mainstream macroeconomics today and showing how macroeconomic models build on and relate to each other. The self-contained text begins with models of individual decision makers, proceeds to models of general equilibrium without and with friction, and, finally, presents positive and normative theories of economic policy. After a review of the microeconomic foundations of macroeconomics, the book analyzes the household optimization problem, the representative household model, and the overlapping generations model. It examines risk and the implications for household choices and macroeconomic outcomes; equilibrium asset returns, prices, and bubbles; labor supply, growth, and business cycles; and open economy issues. It introduces frictions and analyzes their consequences in the labor market, financial markets, and for investment; studies money as a unit of account, store of value, and medium of exchange; and analyzes price setting in general equilibrium. Turning to government and economic policy, the book covers taxation, debt, social security, and monetary policy; optimal fiscal and monetary policies; and sequential policy choice, with applications in capital income taxation, sovereign debt and default, politically motivated redistribution, and monetary policy biases. Macroeconomic Analysis can be used by first-year graduate students in economics and students in master's programs, and as a supplemental text for advanced courses.







Macroeconomic Policy


Book Description

This analysis of macroeconomic policy, originally published in 1989, argues that key government objectives, such as reduced inflation, decreased unemployment and an adequate level of national saving can be achieved only by employing both monetary and fiscal policies, in conjunction with supply-side policies expressly designed to improve the workings of the labour market. Part 1 is a comparative analysis showing the effects of monetary and fiscal policy on the economy. Real-wage rigidity in the labour market is shown to have important consequences for the working of both types of policy, because it conditions the economy’s response to tax changes. Part 2 presents an econometric model which combines consistent stock-flow accounts with a full range of expectational effects. Part 3 presents an innovative technique for solving rational expectations models with the need for arbitary terminal conditions.




The Oxford Handbook of Computational Economics and Finance


Book Description

The Oxford Handbook of Computational Economics and Finance provides a survey of both the foundations of and recent advances in the frontiers of analysis and action. It is both historically and interdisciplinarily rich and also tightly connected to the rise of digital society. It begins with the conventional view of computational economics, including recent algorithmic development in computing rational expectations, volatility, and general equilibrium. It then moves from traditional computing in economics and finance to recent developments in natural computing, including applications of nature-inspired intelligence, genetic programming, swarm intelligence, and fuzzy logic. Also examined are recent developments of network and agent-based computing in economics. How these approaches are applied is examined in chapters on such subjects as trading robots and automated markets. The last part deals with the epistemology of simulation in its trinity form with the integration of simulation, computation, and dynamics. Distinctive is the focus on natural computationalism and the examination of the implications of intelligent machines for the future of computational economics and finance. Not merely individual robots, but whole integrated systems are extending their "immigration" to the world of Homo sapiens, or symbiogenesis.




Markups, Gaps, and the Welfare Costs of Business Fluctuations


Book Description

In this paper we present a simple, theory-based measure of the variations in aggregate economic efficiency associated with business fluctuations. We decompose this indicator, which we refer to as 'the gap', into two constituent parts: a price markup and a wage markup, and show that the latter accounts for the bulk of the fluctuations in our gap measure. Finally, we derive a measure of the welfare costs of business cycles that is directly related to our gap variable, and which takes into account explicitly the existence of a varying aggregate inefficiency. When applied to postwar U.S. data, for plausible parametrizations, our measure suggests welfare losses of fluctuations that are of a higher order of magnitude than those derived by Lucas (1987). It also suggests that the major postwar recessions involved substantial efficiency costs.




The Macroeconomic Effects of Public Investment


Book Description

This paper provides new evidence of the macroeconomic effects of public investment in advanced economies. Using public investment forecast errors to identify the causal effect of government investment in a sample of 17 OECD economies since 1985 and model simulations, the paper finds that increased public investment raises output, both in the short term and in the long term, crowds in private investment, and reduces unemployment. Several factors shape the macroeconomic effects of public investment. When there is economic slack and monetary accommodation, demand effects are stronger, and the public-debt-to-GDP ratio may actually decline. Public investment is also more effective in boosting output in countries with higher public investment efficiency and when it is financed by issuing debt.
