U . S . MONEY DEMAND INSTABILITY A Flexible Least Squares Approach *

چکیده
This paper uses a Jle.rrhle leust squares (FLS) time-varying linear regression technique to investiaate coefficient stabilitv for the Goldfeld U.S. money demand model over the period 1959:62 to 19X5:Q3. Time paths traced out by the FLS coefficient estimates exhibit shifts in 1974 and 1983; but these shifts are small relative to a persistent downward trend in the estimated coefficient for the inflation rate, indicating potential model misspecitication. The FLS estimates also indicate that the ‘unit root’ nonstationarity problem reported by OLS money demand studies disappears if the coefficient estimates are allowed to exhibit even small amounts of time variation.

Liquidity Demand of Heterogeneous Firms in the Economy of Iran: Microfoundation Approach
One of the main reasons in economic recession is the liquidity constraints of economic firms. When external finance becomes expensive for firms, money demand will act as a buffer stock. Actually, firms reduce unfavorable effect of liquidity constraints by holding money. In this study, after extracting firms liquidity demand function based on micro foundations and creating an index for firms liq...
متن کاملIs the US Demand for Money Unstable?
The demand for money (M1) for the USA is estimated with annual data from 1960-2008 and its stability is analyzed with the extended Gregory and Hansen (1996b) test. In addition to estimating the canonical specification, alternative specifications are estimated which include a trend and additional variables to proxy the cost of holding money. Results with our extended specification showed that th...
متن کاملA Simple Estimator of Cointegrating Vectors in Higher Order Integrated Systems
Efficient estimators of cointegrating vectors are presented for systems involving deterministic components and variables of differing, higher orders of integration. The estimators are computed using GLS or OLS, and Wald Statistics constructed from these estimators have asymptotic x2 distributions. These and previously proposed estimators of cointegrating vectors are used to study long-run U.S. ...
متن کاملExact and approximate solutions of fuzzy LR linear systems: New algorithms using a least squares model and the ABS approach
We present a methodology for characterization and an approach for computing the solutions of fuzzy linear systems with LR fuzzy variables. As solutions, notions of exact and approximate solutions are considered. We transform the fuzzy linear system into a corresponding linear crisp system and a constrained least squares problem. If the corresponding crisp system is incompatible, then the fuzzy ...
متن کاملAdaptive Estimation of Heteroscedastic Money Demand Model of Pakistan
For the problem of estimation of Money demand model of Pakistan, money supply (M1) shows heteroscedasticity of the unknown form. For estimation of such model we compare two adaptive estimators with ordinary least squares estimator and show the attractive performance of the adaptive estimators, namely, nonparametric kernel estimator and nearest neighbour regression estimator. These comparisons a...
