Monetary policy affects the degree of strategic complementarity in firms' pricing decisions if it responds to the aggregate price level. In normal times, when monopolistic competitive firms increase their prices, the central bank raises interest rates, which lowers consumption demand and creates...

The aim of the paper is to compare the sensitivity of a government's fiscal policy and a central bank's monetary policy, which are in Nash equilibrium in the case of a non-cooperative game between the government and the central bank in Czechia, Hungary, and Romania. The analysis for each country...

We explore the interaction between central bank digital currencies and cryptocurrencies using a game-theoretic model. The solution of this model is characterized by a multiplicity of equilibria, delimited by the regulatory capability of the central bank and its interaction with the financial...

The paper examines whether central banks should be committed to achieving price stability (a low-inflation target), and how strong (explicit) their long-term monetary commitment should be. For that purpose we propose a game theoretic framework that enables us to model various degrees of...

The Crash of 2008 is often blamed on the Fed’s overly ‘loose’ monetary policy after 2001 (see Taylor, 2009, 2010). In short, the argument goes, American monetary policy was too ‘loose’ for four years between 2002 and 2006; and too ‘tight’ once the Fed realised that it was presiding...

This paper generalizes the classical theory of economic policy to a static LQ-strategic context between n players. We show how this generalized version of controllability can profitably be used to deal with policy ineffectiveness issues and Nash equilibrium existence.

The paper examines whether central banks should be committed to achieving price stability (a low-inflation target), and how strong (explicit) their long-term monetary commitment should be. For that purpose we propose a game theoretic framework that enables us to model various degrees of...

The paper studies the relationship between equilibrium existence in LQ games and the classical theory of economic policy, generalizing some recent results. In particular, by focusing on system controllability instead of the controllability by one or some of the players, we find conditions for...

This paper presents a monopolistic competition model of a bank choosing the optimal level of the screening effort in the presence of cross-selling activities. We demonstrate that, in absence of informational synergies, the larger is the range of services that the bank produces, the lower is the...

The theory of economic policy has its roots in the contributions of Tinbergen and Theil, who solved the problem of a policymaker aiming to achieve certain values for his policy targets, or to minimize a loss function defined on those targets, by using the available policy instruments. After...
