Quinoa has evolved considerably in the past decades, becoming consolidated as a fundamental pillar for Andean farming communities and emerging as a prominent actor in the global superfood market. Despite this, prices of this grain have been characterized by complex dynamics, with substantial...

We introduce the vector-valued t-Riesz distribution for time series models of electricity prices. The t-Riesz distribution extends the well-known Multivariate Student's t distribution by allowing for tail heterogeneity via a vector of degrees of freedom (DoF) parameters. The closed-form density...

Quinoa has undergone a remarkable transformation in recent decades, consolidating its position as a fundamental pillar for Andean farming communities and emerging as a prominent player in the global superfood market. However, the prices of this grain have shown complex dynamics, with large...

This paper investigates the causal effect of global value chain (GVC)-related trade on the German labor market during the COVID-19 crisis, using a difference-in-differences approach combined with entropy balancing. The analysis of monthly establishment-level data from January 2019 to December...

This paper investigates nowcasting Growth-at-Risk (GaR) using consensus forecasts from the Survey of Professional Forecasters (SPF) in the US. Incorporating SPF consensus forecasts into the conditional mean of an AR-GARCH type model significantly enhances nowcasting accuracy for GaR and the...

We analyze whether the Olympic Games contribute to a process of democratization in the awarded country, as postulated in the cases of the 2008 and 2014 Olympics, controlling for endogeneity issues that may arise if the decision to award host status by the International Olympic Committee is...
