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 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 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 paper formulates and estimates an open economy monetary DSGE model to investigate the quantitative significance of the financial accelerator mechanism in business cycle fluctuations for African countries. We employ the Bayesian technique to evaluate the statistical importance of the...

The elasticity of intertemporal substitution (EIS) is a crucial parameter in finance and macroeconomics, yet its estimation remains elusive. We show, based on Fisher's relation and the expectations theory of the term structure, that the EIS is the inverse of the product of the average term to...

We derive the new Keynesian IS curve from the Fisher relation and the expectations theory of the term structure, without reference to household preferences. We show that, under certain conditions, parameters of the empirical new Keynesian IS curves need not be estimated but can be calibrated...

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...

The paper builds on the Goodwin (1967) model which describes the distributive cycle of capitalist economies whereby mass unemployment is generated periodically through the conflict about income distribution between capital and labor. We add to this model a segmented labor market structure with...

This paper reviews Thomas Piketty's Capital in the Twenty-First Century. Piketty's Capital seeks to bring the issue of inequality back to the centre of social analysis and to encourage discussion about the evolution of wealth and inequality with a view to inform policy. The book uses data...
