Maximum-likelihood estimation of the variance of the disturbances in a linear regression is considered in the context of exact linear restrictions on the coefficient vector. The exact risk function for the associated ...

By replacing the unknown random factors of factor analysis with observed macroeconomic variables, the arbitrage pricing theory (APT) is recast as a multivariate nonlinear regression model with across-equation restrictions. ...

Michael Pelcovits (1979, p. 307) recently showed that with an unstable foreign excess supply curve, either a fixed quota or a buffer stock program with a fixed tariff can be used to stabilize domestic price at a given level, ...

Recently, several authors have argued for the use for the use of dynamic preference structures for leisure which incorporate forms of intertemporally nonseparable utility in the analysis of intertemporal labor supply decisions. ...

Voltage-dependent membrane currents were studied in dissociated hepatocytes from chick, using the patch-clamp technique. All cells had voltage-dependent outward K+ currents; in 10% of the cells, a fast, transient, ...

Interest in the poverty of U.S. women with children but without husbands stems from numerous sources including (i) the secular growth of this demographic group-up 110 percent since 1970 to a total of 6 million (almost 20 ...

The paper develops a unified theory of likelihood specification testing based on M-estimators of auxiliary parameters. The theory is sufficiently general to encompass a wide class of specification tests including moment-based ...

FISHER and TEMIN (1973) have argued recently that many empirical studies1 relating to the Schumpeterian hypothesis are inappropriate for testing that hypothesis. They observe that Schumpeter can be interpreted as hypothesizing ...
