Under a conventional policy rule, a central bank adjusts its policy rate linearly according to the gap between inflation and its target, and the gap between output and its potential. Under 'the opportunistic approach to disinflation' a central bank controls inflation aggressively when inflation...

The inflation targeting policy, which is adopted in a lot of countries in recent years, has been introduced with a band target in most countries. However, in the many theoretical analysis, the target of the inflation rate is assumed to be a point, and the studies that have treated the following...

This paper examines the role of a policymaker in macroeconomic outcomes. To determine the possible trade-offs posed by various policy targets, we link a well-known aggregate supply function with a policy rule. In our model we determine the conditions and explore the possibility under which a...

Under a conventional policy rule, a central bank adjusts its policy rate linearly according to the gap between inflation and its target, and the gap between output and its potential. Under the opportunistic approach to disinflation a central bank controls inflation aggressively when inflation is...

We analyse the stability of countries within a monetary union in the face of asymmetric shocks, using a simple but widely applicable model. We show that members of the union may be subject to severe cycles following asymmetric shocks if there is a significant backward looking element in...

In this paper we derive optimal monetary targeting rules under various assumptions about fiscal behavior. In contrast to the existing literature we use a linear-quadratic approach and allow for dynamic games between the two policy authorities. It is shown that optimal monetary behavior is...

In this paper, we examine how economic shocks affect the distribution of household inflation expectations. We show that the dynamics of households' expected inflation distributions are driven by three distinctive functional shocks, which influence the expected inflation distribution through...

This paper reviews the post-Keynesian theory of inflation against the background of the simultaneous rise in inflation and profit shares in the course of the Covid-19 recovery and the Russian war in Ukraine. It distinguishes between the Keynes, Kaldor, Robinson, and Marglin tradition, and the...

The return of inflation in Western economies has fueled the debate on its main drivers, bringing sector-specific shocks and supply chain bottlenecks to the forefront. Building on the seminal approach of Weber et al. (2024), this paper develops a method to assess the degree of exposure to these...

In this paper, I use firm-level data from Compustat to document the evolution of markups among listed U.S. non-financial firms during the height of the COVID-19 pandemic (2020-2022). I show that, continuing its long-term rise, the aggregate (sales-weighted) markup rises markedly in 2020 and...
