Abstract

This paper provides a comparative, time-varying assessment of how macroeconomic skewness affects the business cycle in the US, Canada, and the UK. We construct novel aggregate skewness factors for Canada and the UK, alongside a US benchmark, and embed these indicators in country-specific time-varying parameter VAR models with stochastic volatility. Our results show that negative skewness shocks consistently depress output and equity prices, raise unemployment, and trigger monetary easing, while generating generally modest disinflationary effects. Crucially, the macroeconomic transmission of skewness is highly state-dependent: responses are markedly larger and more persistent during major downturns, particularly the global financial crisis and the COVID-19 episode, while remaining muted during tranquil expansions.
