This paper investigates the identification, the determinacy and the stability of ad hoc, "quasi-optimal" and optimal policy rules augmented with financial stability indicators (such as asset prices deviations from their fundamental values) and minimizing the volatility of the policy interest...

This paper shows that a shift from Ramsey optimal policy under short term commitment (based on a negative-feedback mechanism) to a Taylor rule (based on positive-feedback mechanism) in the new-Keynesian model is in fact a Hopf bifurcation, with opposite policy advice. The number of stable...

We present the first necessary and sufficient conditions for the existence of a unique perfect-foresight solution, returning to a given steady-state, in an otherwise linear model with occasionally binding constraints. We derive further conditions on the existence of a solution in such models,...

This paper demonstrates the existence of a finite set of equilibria in the case of the indeterminacy of linear rational expectations models. The number of equilibria corresponds to the number of ways to select n eigenvectors among a larger set of eigenvectors related to stable eigenvalues. A...

This algorithm extends Ljungqvist and Sargent (2012) algorithm of Stackelberg dynamic game to the case of dynamic stochastic general equilibrium models including exogenous forcing variables. It is based Anderson, Hansen, McGrattan, Sargent (1996) discounted augmented linear quadratic regulator....

Much has been written on the relationship of China and Africa in the past decade. However, the subject of Chinese migrant entrepreneurs in Africa and their articulation with African counterparts was little explored up to the early 2010s. Apparently, this research gap has been closed, as shown by...

In July 2020, the EU Parliament voted in favour of Croatia’s application to become the newest member of the eurozone from January 1, 2023. Despite the setback caused by the COVID-19 pandemic, it met all the criteria for adopting the euro, high inflation, and the impact of Russia’s invasion...

The EU is one of the three largest economies in the world. But its economy, which is still suffering from the cCOVID-19 pandemic and the negative effects of the Russian war in Ukraine, faces a bleak outlook. Inflation, or even stagflation, is a major concern as it reflects cost pressures from...

Pour de nombreux Africains, l'eau n'est pas seulement la source de la vie, mais aussi un moyen de purification et un centre de régénération. Les rituels et les cultes de l'eau, tels que «Mami Wata», conduisent leurs adeptes à la libération du corps et de l'esprit. Mais les rites...
