The paper presents a model of a monetary economy where there are differences in liquidity across assets. Money circulates because it is more liquid than other assets, not because it has any special function. There is a spectrum of returns on assets, reflecting their differences in liquidity. The...

A growing theoretical literature argues that aggregate price flexibility and the inflation-output tradeoff faced by central banks should rise with microeconomic price change dispersion. However, there is little empirical work testing this prediction. I fill this gap by estimating time-varying...

Is monetary policy less effective at increasing real output during periods of high volatility than during normal times? In this paper, I argue that greater volatility leads to an increase in aggregate price flexibility so that nominal stimulus mostly generates inflation rather than output...

This paper evaluates the concepts of natural rates of interest and output in Woodford's "neo-Wicksellian" and "benchmark New Keynesian" version of the New Neoclassical Synthesis (NNS) by comparing them with the original approach of Wicksell and critical assessments and adaptations by Lindahl,...

Much recent monetary policy analysis has featured stochastic simulations with small structural macroeconomic models that include: a spending vs. saving ( IS') sector; a price-adjustment sector; and an interest rate policy rule. The first two are frequently specified so as to reflect optimizing...

Existing literature on the strategic interaction between the central bank (CB) and unions assumes that firms face perfect competition on product markets and that inflation is chosen directly by the monetary authority. Although these simplifications have the virtue of making complex strategic...

The effectiveness of alternative loss functions assigned to the common central bank of a monetary union is studied. The alternative policy objectives are a function of the degree of aggregation of decision variables. We consider, respectively, the policy based on the union-wide aggregates and...

Rational inattention theory is economic theory that recognizes that people have finite information-processing capacity, in the sense of Shannon and engineering information theory. This approach is still in the early stages of development, but it promises to provide a unified explanation for some...

Endogenous money is a core component of post-Keynesian economics, but it has not been fully integrated into its macroeconomics. To do so requires replacing the accounting truism that ex post expenditure equals ex post income with the endogenous money insight that ex post expenditure equals ex...

This paper asks why modern finance theory and the efficient market hypothesis have failed to explain long-term carry trades; persistent asset bubbles or zero lower bounds; and financial crises. It extends Godley and Lavoie (Monetary Economics: An Integrated Approach to Credit, Money, Income,...
