This note considers Tobin's average Q in a framework where firms finance investment by equities and debt. The determination of its long-run equilibrium value Q° is based on positing equality of the loan rate and, adjusted for a risk premium, the return on equities. Q° can thus be characterized...

The Keynesian stability condition is a necessary assumption for the IS equilibrium concept to make economic sense. With reasonable values for the saving parameter(s), however, it typically implies excessively strong multiplier effects. This is more than a cosmetic issue, not least because any...

This paper derives firms' desired rate of utilization from an explicit maximization of a conjectured rate of profit at the micro level. Invoking a strategic complementarity, desired utilization is thus an increasing function of not only the profit share but also the actual utilization. Drawing...

Concentrating on speculative flow rather than stock demand, the paper puts forward a deterministic continuous-time model of the equity market that is compatible with a growing and inflationary economy. Instead of the systematically rising equity price, the central state variable in now Tobin's...

This paper shows that an analytical determinacy analysis of the baseline New Keynesian model with both staggered wages and prices developed by Erceg, Henderson and Levin (2000) is possible despite the high dimensional nature of this model. It is possible if the formulation of the model is...

The paper considers an elementary New-Keynesian three equation model and compares its Bayesian estimation to the results from the method of moments (MM), which seeks to match finite set of the model-generated second moments of inflation, output and the interest rate to their empirical...

With the help of two examples, we illustrate the usefulness of agent-based models as a tool for economic policy design. In our first example, we apply a financial market model in which the order flow of speculators, relying on technical and fundamental analysis, generates intricate price...

This paper analyzes labor productivity and the law of decreasing labor content (LDLC) originally formulated by Farjoun and Machover (1983). First, it is shown that the standard measures of labor productivity may be rather misleading, owing to their emphasis on monetary aggregates. Instead, the...
