This paper studies the effect of forward contracts on the stability of collusion among firms, competing in supply functions on the spot market. A forward market can increase the range of discount factors which allow to sustain collusion. On the contrary, collusion is destabilised when a...

This paper provides a novel rationale for the regulation of market size when heterogeneous firms compete. A regulator seeks to maximize total welfare by choosing the number of firms allowed to enter the market, e.g. by issuing a certain number of licenses. Opening up the market for more firms...

The manufacturing sector accounts for a substantial share of German GDP, employment and carbon emissions. Therefore, the manufacturing sector's energy use and carbon emissions are of crucial importance for reaching Germany's climate goals. In this paper, we analyse energy use patterns in German...

Rising energy prices might lead to adjustments along the supply chain and make firms outsource energy-intensive processes. This could lead to carbon leakage. I provide empirical evidence whether energy price-induced offshoring occurs using firm-level data on energy use, imports, and material...

Carbon emissions from German manufacturing have increased over the past decade, while carbon intensity (emissions per Euro of gross output) has declined only slightly. We decompose changes in emissions between 2005 and 2017 into scale, composition (changes in the mix of goods produced) and...

The cost and revenue earnings potential of alternative power generation sources has shifted considerably in recent years. Here we introduce the concept of Levelized Profit Margins (LPM) to capture the changing unit economics of both intermittent and dispatchable generation technologies. We apply...

The parameterisation of energy and climate policies often depends on the technology, which is price-setting in electricity markets. We propose two simple approaches to determine marginal technologies in electricity wholesale from available data. Both approaches are complementary, computationally...

How much information should governments reveal to consumers if consumption choices have uninternalized consequences to society? How does an alternative tax policy compare to information disclosure? We develop a price theoretic model of information design that allows empiricists to identify the...

Drastic emission reductions are necessary to combat climate change. However, despite several climate policies, carbon emissions from German manufacturing have actually increased between 2005 and 2017. In this paper, we provide evidence of how the policy mix overall has affected the German...

Climate policy often implies increasing energy prices. Due to incomplete regulation across the globe, concerns about their competitiveness and employment effects play an important role in the policy debate. Using micro-data on electricity network charges and the official census data for Germany,...
