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,...

Assuming inflation is a forward variable in Taylor (1999) model, this paper finds opposite policy rule recommandations with counter-cyclical policy rule parameters (Taylor principle: inflation rule larger than one and bounded upwards) in the case of optimal policy under commitment versus...

We construct the first algorithm for the perfect foresight solution of otherwise linear models with occasionally binding constraints, with fixed terminal conditions, that is guaranteed to return a solution in finite time, if one exists. We also provide a proof of the inescapability of the...

Famines are almost always man-made often used as a deterrent. Since ancient times, food and hunger have been a weapon of war. Among the most notorious examples in Africa are the Herero and Namaqua genocide in German South-West Africa (now Namibia) from 1904 to 1908. It was the first genocide of...

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...

Sub-Saharan Africa emerged in the past years as global epicentre of Islamist terrorism. The impact of terrorism on the economy has a negative bearing on the formal and a positive effect on the informal sector. Among other things, this is due to the poorly diversified development economies of...

Russia and China challenge the liberal order and rule of law on a global and regional level. The Trump administration has facilitated the support of the move away from the liberal international order and the "Westphalian" system of states that America had defended for centuries. Extremism is...
