To analyze the optimal social insurance package, we set up a two-period life-cycle model with risky human capital investment in which the government has access to labor taxation, education subsidies, and capital taxation. Social insurance is provided by redistributive labor taxation. We point...

We investigate how multinational two-sided platform firms set their prices on intra-firm transactions. Two-sided platform firms derive income from two customer groups that are connected through at least one positive network externality from one group to the other. A main finding is that, even in...

Previous theoretical studies on the debt shifting behavior of multinationals have assumed affiliates of multinationals to be wholly owned. We develop a model that allows a multinational firm to determine both the leverage and ownership structure in affiliates endogenously. A main finding is that...

This paper analyzes optimal linear taxes on labor income and savings in a two-period life-cycle model with ex ante identical households, endogenous leisure demands in both periods, and general processes of skill shocks over the life cycle. We demonstrate that the Atkinson–Stiglitz theorem...

In a two-period world with endogenous savings and two assets, the optimal tax structure and optimal diversification of aggregate (capital) risk between private and public consumption are analyzed. We show that there is no trade-off between efficiency in intertemporal consumption and allocation...
