Residential heating is responsible for one-fifth of Germany’s energy consumption. Heating costs were around 562 euros per year for an average apartment in 2016, which is more than a 13th month’s rent minus heating costs (Kaltmiete). These are the findings of the 2016 Heat Monitor, published...

In Deutschland wird seit 1978 durch staatliche Energieeffizienzmindeststandards versucht, den Heizenergieverbrauch in Wohngebäuden zu reduzieren. So sollen Kosten verringert, die Abhängigkeit von Energieimporten reduziert und, im Rahmen der nationalen Klimaschutzbemühungen, die CO2-Emissionen...

This note demonstrates that in applied regression analysis, the variance of a coeffi cient of interest may decrease from the inclusion of a control variable, contrasting with Clarke’s assertion (2005, 2009) that the variance can only increase or stay the same. Practitioners may thus be...
