This paper explores some of the implications for econometric practice of the principle that people's observed behavior will change when their constraints change. In dynamic contexts, a proper definition of people's constraints includes among them laws of motion that describe the evolution of the taxes they must pay and the prices of the goods that they buy and sell. Changes in agents' perceptions of these laws of motion (or constraints) will in general produce changes in the schedules that… 

Forecasting the Forecasts of Others

This paper explores the formulation and analysis of linear equilibrium models of investment in which learning is perpetual and informationally decentralized firms need never share the same beliefs

Counterfactuals, Forecasts, and Choice-Theoretic Modelling of Policy

This paper focuses on the problem of formulating an analysis of economic policy that is consistent with rational expectations. Cooley, LeRoy,and Raymon show that the Lucas and Sargent strategy for

Econometric Policy Evaluation: Note

for successive values of the endogenous variables y,, with the x, treated as deterministic forcing variables. Here 0 is a parameter vector and the Et are random shocks. Lucas correctly observed that

Fiscal Foresight: Analytics and Econometrics

Fiscal foresight---the phenomenon that legislative and implementation lags ensure that private agents receive clear signals about the tax rates they face in the future---is intrinsic to the tax

Stochastic models in dynamic economics: problems of time inconsistency, causality and estimation

The theory of feedback and optimal control, originally developed for and applied most successfully in physical and engineering systems, has found many applications in dynamic economics for over two

Quantitative Theory and Econometrics

Quantitative theory uses simple, abstract economic models together with a small amount of economic data to highlight major economic mechanisms. To illustrate the methods of quantitative theory, we

Recursive Models of Dynamic Linear Economies

A common set of mathematical tools underlies dynamic optimization, dynamic estimation, and filtering. In Recursive Models of Dynamic Linear Economies, Lars Peter Hansen and Thomas Sargent use these

The Political Manipulation of Macroeconomic Policy

Conventional wisdom and some research indicate that macroeconomic policies follow cycles corresponding to political, as well as economic, forces. Using vector autoregression analysis, I test three

Economic and econometric models





The paper investigates an econometric method for selecting macroeconomic policy rules when expectations are formed rationally. A simple econometric model of the U.S. is estimated subject to a set of

Theory of the Consumption Function

What is the exact nature of the consumption function? Can this term be defined so that it will be consistent with empirical evidence and a valid instrument in the hands of future economic researchers


Given n observations on a system of linear stochastic difference equations with appropriate initial conditions, and given a prior density (possibly diffuse) of its parameters, this paper obtains the

Stabilizing Powers of Monetary Policy under Rational Expectations

The potential of monetary policy to stabilize fluctuations in output and employment is demonstrated in a stochastic rational expectations model in which firms choose, considering average

The Macroeconomic Impact of Changes in Income Taxes in the Short and Medium Runs

The effects of an unexpected change in income taxes are studied in a model with full rational expectations. In the short run, aggregate supply is quite price elastic because commitments to pay

Simulation Methodology in Macroeconomics: An Innovation Technique

This paper discusses a simulation procedure where innovations from time-series processes are used in conducting simulation experiments with macroeconometric models. A particular theoretical example

Long-Term Contracts, Rational Expectations, and the Optimal Money Supply Rule

The paper is concerned with the role of monetary policy and argues that activist monetary policy can affect the behavior of real output, rational expectations notwithstanding. A rational expectations
