Distinguishing between the confounding effects of temporal dependence, variation in exogenous factors and residual heterogeneity over and above that due to measured explanatory variables is a major challenge to be confronted in any analysis of panel or similar longitudinal data. This paper...

The generalized estimating equation (GEE) approach to the analysis of longitudinal data has many attractive robustness properties and can provide a 'population average' characterization of interest, for example, to clinicians who have to treat patients on the basis of their observed...

The thesis presents several theoretical models on the causes and consequences of income growth and uncertainty.Part I deals with international trade as a major source of aggregate productivity. It presents the Melitz (2003) model and develops an integrated model of intra-industry trade and...

This paper uses affiliate level data from Swedish multinationals to examine the impact of tax treaties on both overall affiliate sales and the composition of those sales. In line with previous results, we find little evidence for an effect of treaties on the level of total sales. We do, however,...

This paper empirically examines whether expansion of the EU has increased international tax competition. To do so, we use a simple model of tax competition to determine how a given country weights the taxes of others when choosing its own tax. This indicates that the market potential of a...

Heterogeneous firm productivity raises the question of whether governments should pursue `pick-the-winner' strategies by subsidizing highly productive firms more, or taxing them less, than their less productive counterparts. We study this issue in a setting where governments can set...

Governments worldwide use targeted tax policies to trade off the gains from increased FDI against the cost of excessive profit shifting by multinational firms. We show that optimal tax systems generally incorporate both thin capitalization rules, which tax discriminate between purely national...

Several countries have recently introduced national capital standards exceeding the internationally coordinated Basel III rules, which is inconsistent with the `race to the bottom' in capital standards found in the literature. We study regulatory competition when banks are heterogeneous and give...
