Why did some Bolivian departments have more success containing COVID-19 than others? We argue that low government legitimacy hampers coordinated responses to national crises, particularly where political polarization is severe and the crisis response becomes politicized. Low can intensify challenges of poverty poor infrastructure. An original dataset daily observations on subnational coronaviru...

Dynamic voltage and frequency scaling (DVFS) is a technique for adjusting the speed and power consumption of processors, allowing performance to be traded for reduced power consumption. Since CPUs are typically the largest consumers of power in modern servers, DVFS can have a significant impact on overall server power consumption. Modern operating systems include DVFS governors, which interact ...

We propose two new jump-robust estimators of integrated variance based on high-frequency return observations. These MinRV and MedRV estimators provide an attractive alternative to the prevailing bipower and multipower variation measures. Specifically, the MedRV estimator has better theoretical efficiency properties than the tripower variation measure and displays better finitesample robustness ...
