Foreign exchange (FX) trading volume is a key factor in exchange rate volatility. Given the important role of volatility in economic growth and stability, this paper investigates the dynamic nature of exchange trading volume on exchange rate volatility using hourly high-frequency data. The...

Over the past few decades, fiscal policy has been about 30 percent more procyclical and about 40 percent more volatile in commodity-exporting emerging markets and developing economies (EMDEs) than in other EMDEs. Both procyclicality and volatility of fiscal policy-which share some underlying...

We develop a score-driven time-varying parameter model where no particular parametric error distribution needs to be specified. The proposed method relies on a versatile spline-based density, which produces a score function that follows a natural cubic spline. This flexible approach nests the...

We utilize Bayesian model averaging to estimate a stochastic discount factor (SDF) for single-stock options. A Bayesian model averaging SDF outperforms reduced-form benchmark models in-sample and out-of-sample in pricing option return anomalies and portfolios. We document that the SDF is dense...

Countries facing commodity (net) export price shocks tend to implement fiscal rules and to financially close their economies, demonstrating "macroeconomic prudence". These effects are (unsurprisingly) asymmetric between import and export price shocks. The impact of commodity (net) export prices...

European electricity markets are in the midst of unprecedented changes-caused by Russia's invasion of Ukraine and the rise of renewable sources of energy. Using high-frequency data, this paper investigates volatility spillovers across 24 countries in the European Union (EU) during the period...
