This study investigates the predictability of a fixed uncertainty index (UI) for realized variances (volatility) in the international stock markets from a high-frequency perspective. We construct a composite UI based on the scaled principal component analysis (s-PCA) method and demonstrate that...

We use UK transaction-level data during the Covid-19 pandemic to study whether mortgage payment holidays (PH) can act as a mechanism for smoothing household consumption following negative aggregate shocks. Our results suggest that mortgage PH were accessed by both households with pre-existing...

This paper proposes an Exponential HEAVY (EHEAVY) model. The model specifies the dynamics of returns and realized measures of volatility in an exponential form, which guarantees the positivity of volatility without restrictions on parameters and naturally allows the asymmetric effects. It...

We examine the supply-side characteristics - unskilled labor, imported input intensity, dependence on inputs from China, production complexity - that determine different potential vulnerabilities of traded products to the COVID-19 pandemic. Relying on monthly exports at the product level by all...
