During the latest decades, household mortgage loans have increased substantially in many countries. We develop an OLG model where housing is a positional consumption good (such that housing choices are partly driven by relative consumption concerns), and where the consumers are also...

A significant part of the revenue in the EU budget is raised via a GNI-based resource. The purpose of this paper is to analyze how this way of raising funds to the central authority in an economic federation affects the tax policy implemented by the lower level jurisdictions. This question is...

This paper shows how the first-best and second-best rules for optimal public good provision depend on the adaptation to private and public consumption. Adaptation in private consumption typically leads to over-provision relative to the Samuelson condition, while adaptation in public consumption...

This paper deals with optimal income taxation based on a model with households where men and women allocate their time between market work and household production, and where households differ depending on which spouse has comparative advantage in market work. The purpose is to analyze the tax...

Almost all previous studies on public policy under relative consumption concerns have ignored the role of leisure for status comparisons. Inspired by Veblen (1899), this paper considers a two-type optimal income tax model, where people care about their relative consumption, and where the...

This paper deals with optimal income taxation under international outsourcing and FDI. We show how the joint effect of outsourcing and FDI on the optimal marginal income tax rates depends on whether FDI is horizontal or vertical.

Earlier literature on tax competition and policy coordination typically assumes that the labor market is competitive; a description less suitable for Europe, where trade unions have had a strong position in the labor market for a long time. This paper concerns factor income taxation and public...

This thesis consists of an introductory chapter and four papers, which relate to environmental policy in the presence of transboundary environmental damage. Paper [I] concerns public policy in a multi-jurisdiction framework with transboundary environmental damage. Each jurisdiction is assumed...

This paper addresses transboundary environmental problems in the context of an optimal tax problem, when part of the labor force is mobile across countries. The policy instruments include both commodity taxation and nonlinear income taxation. We show how the tax policy in a noncooperative...

This thesis consists of a summary and four papers. The first two papers are theoretical contributions within the area of optimal taxation and public expenditures under asymmetric information between the government and the private sector, and the last two are empirical contributions to the...
