I investigate the effect of open source on standardization outcomes in a market with positive network externalities. In a closed source world, it seems reasonable to assume that the probability of a standard being chosen is positively correlated with its quality. Open source may weaken or invert...

There is still hardly any empirical evidence on how divergent broadband technologies, and, by extension, bandwidth levels, influence GDP growth, or on the extent of spatial externalities at a regional level. Our study aims to assess the economic benefits of high-speed broadband networks within...

The economics literature on Net Neutrality (NN) has been largely critical of NN regulation on the basis of theoretical findings that NN violations can be both welfare improving and welfare deteriorating, depending on the circumstances of the case in question. Thus, an ex post competition policy...

We analyze competition between Internet Service Providers (ISPs) where consumers demand heterogeneous content within two Quality-of-Service (QoS) regimes, Net Neutrality and Paid Prioritization, and show that paid prioritization increases the static efficiency compared to a neutral network. We...

The Covid-19 pandemic has sparked hope that firm digitalisation will result in long-lasting reductions in mobility and related carbon missions via the use of working from home and online services. In this study, we quantify the extent to which firm digitalisation can be associated with changes...

This paper studies the effects of the high-speed internet expansion on the match quality of new hires. They combine data on internet availability at the local level with German individual register and vacancy data. Results show that internet availability has no major impact on the stability of...

We design the profit-maximizing mechanism to sell an excludable and nonrival good with network effects. Buyers have heterogeneous private values that depend on how many others also consume the good. In optimum, an endogenous number of the highest types shares consumption, and we provide an...

This policy report studies the effects of a sudden stop of natural gas imports from Russia on the German economy. The analysis focuses on the supply-side effects that arise when a gas shortage affects production in the gas-intensive manufacturing sectors, with a corresponding production...

Reverse stress tests are a relatively new stress test instrument that aims at finding exactly those scenarios that cause a bank to cross the frontier between survival and default. Afterward, the scenario which is most probable has to be identified. This paper sketches a framework for a...
