This paper analyses how labour market heterogeneity affects unemployment, productivity and business cycle dynamics that are relevant for monetary policy. The model matches remarkably well the short and long run dynamics of skilled and unskilled workers. Skill mismatch and skill-specific labour...

This study examines whether and how important it is to adjust output gap frameworks during the COVID-19 pandemic and similar unprecedentedly large-scale episodes. Our proposed modelling framework comprises a Bayesian Structural Vector Autoregresion with an identification setup based on a...

In this paper we explore whether the changing composition of output in response to technology shocks can play a significant role in the propagation of shocks over time. For this purpose we study two multisector RBC models, with two and three sectors. We find that, whereas the two-sector model...

Given its consumptionist nature, economic activities in Nigeria are mainly driven by household aggregate consumption expenditure with greater percentage of the spending on consumer-goods-importation. A statistical performance-illustration of the sectoral components of Nigeria's gross domestic...

Following an unparalleled rise in uncertainty over the Great Recession, the US economy has been experiencing anaemic productivity growth. This paper offers a quantitative study on the link between uncertainty and low productivity growth. Firstly, using micro level data I show that uncertainty...

In this chapter, we outline the reasons why economics has been concerned with non-linear dynamics, with a particular focus on business cycles and on economic growth. Using varying perspectives, we discuss the salient historical mathematical approaches to the problem and the results that were...
