One of the fastest-developing areas of political science studies the relationship between the different branches of government. Within that literature, the most popular research questions concern the delegation of powers by one branch to another, the resulting levels of discretion of the...

This paper empirically investigates the relationship between long-run economic growth and output volatility. There is an emerging theoretical literature on the topic which is inconclusive on the size and direction of the relationship. We analyze this relationship empirically for the time series...

Economic theories are increasingly popular in political science, and in particular in research on the relations between the legislative, the executive, and the judicial branches of government. Among these theories, principal-agent (´PA´) and transaction cost economics (´TCE´) feature...

We focus on the recent experience of Ghana, where a National Health Insurance Scheme (NHIS) became law in 2003 and fully implemented from late...

Smart Grids require innovations in the electricity networks, mainly on the level of the distributed system operator (DSO). A main objective is to increase the share of distributed generation (DG) connected to that network level, but also to enable load management on the demand side. This paper...
