An agent with two-parameter, mean-variance preferences is called variance vulnerable if an increase in the variance of an exogenous, independent background risk induces the agent to choose a lower level of risky activities. Variance vulnerability resembles the notion of risk vulnerability in the...

In this paper the welfare state is considered as insurance device. Redistributive taxation reduces the variance of life- time risk. Behind a veil of ignorance with regard to future position in society, agents decide in a two-parametric expectation/standard deviation-approach about labour supply...

Within a two-country model with involuntary unemployment, this paper investigates corporate income taxation under separate accounting versus formula apportionment. In contrast to separate accounting, under formula apportionment the corporate tax policy causes a fiscal externality which goes back...

This paper contributes to the discussion on Separate Accounting versus Formula Apportionment in the corporate income taxation of multinational enterprises (MNEs). The innovation of the analysis is that we consider a general equilibrium tax competition model with an endogenously determined world...

Properness has been introduced in the expected utility framework and it recently has been transfered to mean-variance utility functions. Here, we show that properness implies the slope of the mean-standard deviation indifference curve being convex in the standard deviation. This indifference...

This note provides an alternative proof for the equivalence of decreasing absolute prudence (DAP) in the expected utility framework and in a two-parametric approach where utility is a function of the mean and the standard deviation. In addition, we elucidate that the equivalence of DAP and the...

This paper contributes to the discussion on Separate Accounting versus Formula Apportionment in the corporate income taxation of multinational enterprises. The innovation is that we consider a general equilibrium tax competition model with an endogenous interest rate. In contrast to previous...

In the present paper we extend the classical tax-competition framework of Zodrow and Mieszkowski (1986) by modelling involuntary unemployment and by allowing for labour taxation as a second source of public funds. For a large class of production functions (including CES), it turns out that tax...

This paper provides a rationale for subsidizing green (renewable) energy production. Within a multi-country model where energy is produced with mobile capital in green and dirty production, we investigate the countries’ decentralized choice of emissions taxes and green energy subsidies....
