We derive a traditional Phillips curve under the assumption that firms optimize their prices in the context where a fraction of their output is contracted on previous prices, and where they face potential losses and gains from such contracts. Our derivation delivers an augmented exact...

We derive the backward-looking Keynesian wage-price spiral from micro-foundations. The optimal price Phillips curve features one lag of price inflation, the lag of the labour share, excess demand pressure, speed-limit effects and supply shocks. The wage Phillips curve features current and lagged...

We investigate inflation dynamics and the presence of the cost channel in ten emerging markets since the 1990's from the new Keynesian and triangle Phillips curve perspectives. A negative sign on the output gap is a common finding in new Keynesian specifications. This problem may be addressed by...

We propose a solution to address the observed negative sign on the marginal cost variable in new Keynesian Phillips curve estimations. Our solution is based on an elaborate specification of the cost function faced by firms and the formulation of a reduced-form production function which is...

The recent global financial crisis has increased interest in macroeconomic models that incorporate financial linkages. Here, we compare the simulation properties of five mediumsized general equilibrium models used in Eurosystem central banks which incorporate such linkages. The financial...

We construct an open-economy DSGE model with a banking sector to analyse the impact of the recent credit crunch on a small open economy. In our model the banking sector operates under monopolistic competition, collects deposits and grants collateralized loans. Collateral effects amplify monetary...
