The Costs of Power Interruptions in Germany: A Regional and Sectoral Analysis

A high standard of security of electricity supply comes at serious electricity system costs. However, these system costs have to be balanced with the economic costs induced by an insecure supply of electricity. Following a macroeconomic approach, we analyze the economic costs imposed by potential power interruptions in Germany. Using an extensive dataset on industries and households, we estimate both Values of Lost Load and the associated hourly costs of power interruptions for different German regions and sectors. We find that interruption costs vary significantly over time, between sectors and regions. Peaking at midday on a Monday in December at 750 Mio € per hour, the average total national outage costs amount to approximately 430 Mio € per hour. A missing gigawatt hour creates average outage costs of about 7.6 Mio €.     

Convergence in a Dynamic Heckscher–Ohlin Model with Land

Convergence among nations that share the same preferences and technologies is a key result of the closed‐economy neoclassical growth framework that has received substantial support in the data. However, Heckscher–Ohlin versions of the two‐sector neoclassical growth model predict that nations that differ in their capital–labor ratios may not converge to the same steady state, even if they are identical in all other aspects. This is a puzzling result that warns us about potential dangers of international trade. In this paper we show that when land, an input in fixed supply, is introduced into the model, international trade in goods no longer limits the capacity of poor nations to catch up with the advanced world.
