Recent evidence suggests that macroeconomic outcomes are inferior in countries operating under presidential regimes compared with those with parliaments, with lower levels of economic growth, higher rates of inflation, and higher levels of income inequality in countries with presidential governments. Despite this, more heads of state look to consolidate and build their executive power. This book considers why presidential regimes, in particular, are so bad for the economy.

Throughout the book, the authors comprehensively and simultaneously consider the impact of legal, political, and economic institutions on the mechanisms. It is first demonstrated that presidential countries have (on average) inferior outcomes relative to parliamentary states with respect to these institutions and, moreover, with respect to healthcare and human development indicators. Subsequently, the book explores the impact of constitutional choice (parliamentary versus presidential) on both institutions and macroeconomic outcomes. It is documented that having a presidential regime induces weaker institutions, but that quality institutions can mitigate some of the negative impacts of such regimes.
