A common assumption in macroeconomics is that energy prices are determined in a world-wide, rather frictionless market. This no longer seems an adequate description for the situation that much of Europe currently faces. Rather, one reading is that shortages exist in the quantity of energy...

The paper is concerned with determinacy in a version of the New-Keynesian model that integrates imperfect competition and nominal price and wage setting on goods and labour markets. The model is reformulated with an explicit period of arbitrary length and shown to remain well-defined as the...

This paper analyzes conditions for determinacy in a new Keynesian model with endogenous growth. Endogenous growth shrinks the determinacy region considerably. Complying with the Taylor principle is not sufficient for determinacy, which decreases in the spillovers from actual on potential output....

We introduce rule-of-thumb consumers in an otherwise standard dynamic sticky price model, and show how their presence can change dramatically the properties of widely used interest rate rules. In particular, the existence of a unique equilibrium is no longer guaranteed by an interest rate rule...
