Accountability is one of the cornerstones of good governance. Establishing accountable governments is a top priority on the international development agenda. Yet, scholars and democracy practitioners know little about how accountability mechanisms develop and thus can be supported by international and national actors. The present study tackles the questions of how, and in what sequence accountability sub-types develop. We consider not only vertical (elections and political parties) and horizontal accountability (legislature, judiciary, and other oversight bodies) but also diagonal accountability (civil society and media) in both their de-jure and the de-facto dimensions. By utilizing novel sequencing methods, we study their sequential relationships in 173 countries from 1900 to the present with data from the new V-Dem dataset. Considering the long-term dimensions of institution building, this study indicates that most aspects of de-facto vertical accountability precede other forms of accountability. Effective institutions of horizontal accountability-such as vigorous parliaments and independent high courts-evolve rather late in the sequence and build on progress in many other areas.Keywords Accountability .

This power of the people to hold political leaders to account is fundamental to representative democracy, hence a key feature of most definitions of democracy (e.g., Dahl 1971Dahl , 1989Schmitter and Karl 1991).

Yet, we know little about how and in what sequence different aspects of accountability evolve. The extant literature provides some suggestions on the sequence of democratization-thus how accountability starts to evolve. Dahl (1971) famously argued that it is conducive if competition among elites evolves before the expansion of participation, and there is some empirical support for this (Wilson 2015, p. 234). And while there are contributions on how one aspect of accountability may strengthen other aspects (e.g., Keane 2009), this study is the first of its kind by investigating if there are generalizable sequences in the evolution of accountability across 35 highly specific institutions with data covering 176 countries and 113 years.Taking Dahl's (1971) famous axiom as a point of departure, we argue that governments are more likely to allow for de-facto accountability if the costs of supplying accountability decrease and the costs of suppressing the demand for accountability increase.
