On our interpretation, real bills advocates favor unfettered intermediation, while their critics, who we call quantity theorists, favor legal restrictions on intermediation geared to separate “money” from “credit.” We display examples of economies in which quantity-theory assertions...

Commodity money is modeled as one or two of the capital goods in a one-consumption good and one or two capital-good, overlapping generations model. Among the topics addressed using versions of the model are (i) the nature of the inefficiency of commodity money; (ii) the validity of...

This paper constructs a model with two structural equations: the Government budget constraint and a linear version of Cagan’s portfolio balance equation. The model contains a continuum of equilibria with “sunspot equilibria.” Closed forms for the solutions are found. Even though there is a...

This paper presents estimates of the productivity and factor bias effects of interindustry Ramp;D spillovers for five high-tech industries. Each industry is distinguished as a separate spillover source. The industries are each affected by Ramp;D spillovers and are themselves spillover sources....

In this paper we look at some empiricel evidence of and theoretical rationale for price inflexibility in the face of a decrease in short run demand in the Western-type industrialized economies. The empirical evidence suggests that price sluggishness is pervasive but varies across markets,...

In this paper an attempt is made to answer two questions:1) What set of factors explains the recent slowdown of the U.S. aggregate labor productivity, and 2) whether the same set of forces account for the slowdown of sectoral productivity growth as well. We specify a model which relates measured...
