Harry Johnson's 1971 ideas about the factors affecting the success of the Keynesian Revolution and the Monetarist Counter-revolution are summarised and extended to the analysis of the Rational Expectations - New Classical (RE-NC) Revolution It is then argued that, whereas Monetarism brought...

This paper provides a look into what Lucas meant by the term ‘analogue systems’ and how he conceived making them useful. It is argued that any model with remarkable predictive success can be regarded as an analogue system, the term is thus neutral in terms of usefulness. To be useful Lucas...

This introductory paper offers a look into the intellectual and technical progress that led Robert E. Lucas to his seminal paper entitled Expectations and the neutrality of money. It is argued that the neutrality paper applies the capital-theoretic approach of Lucas’s firm microeconomics of...

This paper offers a critical survey of the three overlapping domains of the phygital world: the Web, the Infosphere, the Metaverse, and their innovative components – blockchain, distributed ledger technology, cryptoassets and cryptocurrencies. This requires a (bold) attempt to synthetize the...

The uniqueness of bounded local equilibria under interest rate rules is analyzed in a model with sticky information à la Mankiw and Reis (2002). The main results are tighter bounds on monetary policy than in sticky-price models, irrelevance of the degree of output-gap targeting for determinacy,...

We derive the optimal monetary policy in a sticky price model when private agents follow adaptive learning. We show that this slight departure from rationality has important implications for policy design. The central bank faces a new intertemporal trade-off, not present under rational...

We derive necessary and suffcient conditions for simple monetary policy rules that guarantee equilibrium determinacy in the New Keynesian monetary model. Our modeling framework is derived from a fully specified optimization model that is still amenable to analytical characterisation. The...

This paper considers a prototypical monetary business cycle model for the U.S. economy, in which the equilibrium is undetermined if monetary policy is ‘inactive? In previous multivariate studies it has been common practice to restrict parameter estimates to values for which the equilibrium is...

Imposing the natural rate hypothesis (NRH) can dramatically alter the determinacy bounds on monetary policy by closing the output gap in the long run. I show that the hypothesis eliminates any role for the output gap in determinacy and renders the conditions for determinacy identical for all...

Most studies of optimal monetary policy under learning rely on optimality conditions derived for the case when agents have rational expectations. In this paper, we derive optimal monetary policy in an economy where the Central Bank knows, and makes active use of, the learning algorithm agents...
