Cities increasingly address climate change, e.g. by pledging city-level emission reduction targets. This is puzzling for the provision of a global public good: what are city governments' reasons for doing so, and do pledges actually translate into emission reductions? Empirical studies have...

This paper sets out a simple dynamic probabilistic voting model in which a government allocates a fixed budget across electoral districts that differ in their loyalty to the ruling party. The model predicts that the geographic pattern of spending depends on the way the government balances...

Centralisation of political decision making often fails to produce the desired results. For instance, it is frequently argued that decision making within the European Union results in overspending and overregulation in some policy areas, while too low spending and too little regulation prevails...
