In conducting empirical investigations of the permanent income model of consumption and the consumption-based intertemporal asset pricing model, various authors have imposed restrictions on the nature of the substitutability of consumption across goods and over time. In this paper we suggest a...

receives private signals about the current values of a subset of the shocks, and (3) the equilibrium price conveys information … about the private signals and beliefs of other traders. Since prices convey information in this economy, traders will face … deduced in various imperfect information environments. Then the volatility and autocorrelations of prices in this model are …

A decentralized market theory of investment based on rising supply price is formulated and explained. Asset prices … embody all available information in a competitive market and serve as "sufficient statistics" for future market conditions …, because it pays to "build ahead of demand" in the presence of rising supply price. This model, similar to q-theory, assumes …

A number of recent studies have attempted to test propositions concerning "long runt" economic relationships by means of frequency-domain time series techniques that concentrate attention on low frequency co-movements of variables.The present paper emphasizes that many of these propositions...

In some applications of the distributed lag model, theory requires that all lag coefficients have a positive sign. A …

The paper explains how the Almon polynominal lag specification can be made stochastic in two different ways - one suggested by Shiller and another following the lines of Lindley and Smith. It is shown that both the estimators can be considered as modified ridge estimators. The paper then...

Standard inference in cointegrating models is fragile because it relies on an assumption of an I(1) model for the common stochastic trends, which may not accurately describe the data's persistence. This paper discusses efficient low-frequency inference about cointegrating vectors that is robust...

Recently there has been a great deal of interest in studying monetary policy under model uncertainty. We point out that different assumptions about the uncertainty may result in drastically different robust' policy recommendations. Therefore, we develop new methods to analyze uncertainty about...
