Chapter 7. Democracy
Chapter Overview
This chapter begins by defining democracy and examining the three waves of democracy that
resulted in more people living in democracies than in dictatorships for the first time in history. It
then turns to examine presidential and parliamentary forms of democracy, and the strengths and
weaknesses of each. Next it discusses how electoral rules determine the number of candidates
elected from districts, how votes obtained by parties and elections are translated into legislative
seats, and the shape of party systems. The following section asks whether democracies do a
better job than authoritarian political systems of promoting economic growth and enhancing
citizens’ capabilities. The chapter ends by testing the hypothesis that democracies do a better job
of enhancing capabilities than authoritarian political systems.
The chapter defines a democracy as a state in which virtually all citizens are able to vote for who
will represent them in free, fair, and periodic elections, and distinguishes between direct and
representative democracy. It then turns to the three waves of democracy. The first had its roots in
the American and French revolutions, the second followed World War II, with the rise of
independence movements in European colonies, and the third dates from 1974, with the collapse
of dictatorship in Portugal followed soon after by the fall of authoritarian regimes in Greece and
Spain. This section also discusses the meaning of the maxim “No bourgeoisie, no democracy”
and reviews contending explanations of why some countries succumbed to the appeal of
democracy while others have resisted.
Having discussed the remarkable historical transition from authoritarianism to democracy in a
large majority of countries in the world, the chapter turns to the forms of democracy. It focuses
on presidential and parliamentary democracy, discussing how they differ from each other and the
strengths and weaknesses of each.
Democracies differ not only in the distribution of power between legislature and executive, but in
electoral systems, which determine how elections are conducted. Some countries have single
member districts in which one legislator is elected from each district, while others have
multimember districts. Countries also differ in how votes gained by candidates and parties are
translated into legislative seats. The three main choices are plurality vote, double-ballot, and
proportional representation rules. Finally, electoral rules help shape party systems with single-
member districts in which candidates win by a plurality, creating a bias toward two-party
systems, and multimember districts and proportional representation creating a bias toward
multiparty systems. Electoral rules are not neutral. Different rules benefit different groups and
parties, making electoral rules the focus of intense political struggle.
One of the longstanding controversies in comparative politics is whether democracies are more
successful in promoting economic development than authoritarian political systems. There are
advocates for both types of political system. Some of the best recent research concludes that
neither has a clear advantage in promoting economic growth.
But does one have an advantage in enhancing citizens’ capabilities? The final section tests the
relationship between the level of democracy and physical well-being, informed decision-making,
and safety. The results are mixed. Countries with the highest democratic scores had lower infant
