The nexus between income and happiness is very much disputed. Many cross-sectional studies see a positive relationship, most longitudinal studies don't. Starting from the fact that the theoretical basis in happiness research has been comparatively weak, we develop a model that identifies...

Studies on EU enlargement mostly focus on its welfare-economic and much less so on its public-choice dimension. Yet, the latter may be as important as the former when it comes to sustain integration. This paper aims at filling the gap by exploring theoretically and empirically how enlargement of...

How globalization affects happiness is highly disputed. Several studies use an index that amalgamates globalization's different dimensions into a single variable. Unlike previous studies and in order to better illuminate its facets, we adopt a disaggregated perspective on trade (policy) data....

In international relations, short-run incentives for non-cooperation often dominate. Yet, (external) institutions for enforcing cooperation are hampered by national sovereignty, supposedly strengthening the role of selfenforcing mechanisms. This paper examines their scope with a focus on...

There has been an intense debate as to the effects of offshoring and global value chains on labor, with the debate centering around possible negative employment and income effects for the low(er) skilled in advanced economies. Although sociological and psychological research has shown that...

Taking Macur Olson´s theory of the decline of nations as pathbreaking in this field we develop a formal model of the behavior of interest groups and their interaction to win some deeper insights into the interior mechanics of the interest-group-state. Followed by a brief survey of empirical...

With interest groups significantly affecting economic performance (according to Mancur Olson) and a vital interest of governments in economic growth and low unemployment in order to win elections, there should be a link between political business cycles and the evolution of lobbies over time...

Mancur Olson's theory of the decline of nations is path-breaking in political economics. It has been tested cross-sectionally in numerous empirical studies. We survey the existing results briefly, with a special focus on studies using the number of lobbies as an exogenous variable. Using data...

Previous studies were plagued with considerable problems when interpreting and empirically analysing Wagner's Law. Therefore, we initially present some kind of "pure theory of government's share" for a two-person society based on the pure theory of public and private goods as originally...

We examine whether the Samuelsonian definition of public goods can be reconciled with "Wagner's Law", that is, public expenditures outpacing economic growth. While both predominantly focus on the demand-side, they differ with respect to their socio-political foundations. Taking the latter into...
