The multivariate Vasicek model is commonly used to capture mean-reverting dynamics typical for short rates, asset price stochastic log-volatilities, etc. Reparametrizing the discretized problem as a VAR(1) model, the parameters are oftentimes estimated using the multivariate least squares (MLS)...

This study analyzes the impact of research and development (R&D) investment on economic growth in Panama, an emerging economy with structural challenges in its innovation system. Using a multivariate econometric approach that included elastic net regularization and fixed-effect panel data...

In European intraday electricity markets, a systematic zigzag pattern can be observed, characterized by alternating maxima and minima at the shift of hourly products. This price formation contradicts the fundamental understanding, that prices to are a monotonously increasing function of residual...
