This Research Paper contains a detailed documentation of the dynamic computable general equilibrium model PuMA. The model is used for analysing economic, labour market and public finance effects of different policy options, structural changes and other important policy questions. PuMA is similar...

This study is the first systematic discussion of potential risk transfer options for cyber risks. We compare several risk transfer options, including insurance, reinsurance and alternative risk transfer. Moreover, we discuss the potential role of the government and the capacity of insurance...

Under simple majority voting an absolute majority of voters may choose policies that are harmful to minorities. It is the purpose of sub- and super-majority rules to protect legitimate minority interests. We study how voting rules are chosen under the veil of ignorance. In our experiment,...

The paper compares the welfare properties of two competing organizations of the monetary system: The current fractional reserve banking system versus a narrow banking system where inside money is fully backed by outside money issued by the central bank.

We concern a sender-receiver game of common interests having infinite types, e.g the set [0; 1]², but with finite signals. In our paper, we extend the game by introducing multiple priors over the type space and use incomplete preferences in Bewley's way. We characterize the equilibria under...

In statistics, samples are drawn from a population in a datagenerating process (DGP). Standard errors measure the uncertainty in sample estimates of population parameters. In science, evidence is generated to test hypotheses in an evidencegenerating process (EGP). We claim that EGP variation...

We study optimal tax design based on the idea that policy-makers face trade-offs between multiple margins of redistribution. Within a Mirrleesian economy with earnings, consumption and retirement savings, we derive a novel formula for optimal income and savings distortions based on...
