Despite the popularity of direct democracy in recent decades, research on the actual output effects of popular decision-making is rare. This is especially true with regard to equality, where there are at least three major research gaps: 1) a lack of cross-national analyses; 2) insufficient investigation of the differential effects of different direct democratic instruments on equality; and 3) a failure to distinguish between different aspects of equality, i.e., socioeconomic, legal and political equality. This article takes a first step to tackle these shortcomings by looking at all national referenda in European democracies between 1990 and 2015, differentiating between mandatory, bottom-up and top-down referenda. We find that a large majority of successful direct democratic bills—regardless of which instrument is employed—are not related to equality issues. Of the remaining ones, there are generally more successful pro-equality bills than contra-equality ones, but the differences are rather marginal. Mandatory referenda tend to produce pro-equality outputs, but no clear patterns emerge for bottom-up and top-down referenda. Our results offer interesting, preliminary insights to the current debate on direct democracy, pointing to the conclusion that popular decision-making via any type of direct democratic instrument is neither curse nor blessing with regard to equality. Instead, it is necessary to look at other factors such as context conditions or possible indirect effects in order to get a clearer picture of the impacts of direct democracy on equality.

Direct democracy is seen as a potential cure to the malaise of representative democracy. It is increasingly used worldwide. However, research on the effects of direct democracy on important indicators like socio-economic, legal, and political equality is scarce, and mainly limited to Europe and the US. The global perspective is missing. This article starts to close this gap. It presents descriptive findings on direct democratic votes at the national level in the (partly) free countries of the Global South and Oceania between 1990 and 2015. It performs the first comparative analysis of direct democracy on these continents. Contradicting concerns that direct democracy may be a threat to equality, we found more bills aimed at increasing equality. Likewise, these votes produced more pro- than contra-equality outputs. This held for all continents as well as for all dimensions of equality.

Within the last decades, western democracies have experienced a rise of inequality, with the gap between lower and upper class citizens steadily increasing and a widespread sentiment of growing inequalities also in the political sphere. Against this background, and in the context of the current "crisis of democracy", democratic innovations such as direct democratic instruments are discussed as a very popular means to bring citizens back in. However, research on direct democracy has produced rather inconsistent results with regard to the question of which effects referenda and initiatives have on equality. Studies in this field are often limited to single countries and certain aspects of equality. Moreover, most existing studies look at the mere availability of direct democratic instruments instead of actual bills that are put to a vote. This paper aims to take a first step to fill these gaps by giving an explorative overview of the outputs of direct democratic bills on multiple equality dimensions, analyzing all national referenda and initiatives in European democracies between 1990 and 2015. How many pro-and contra-equality bills have been put to a vote, how many of those succeeded at the ballot, and are there differences between country groups? Our findings show that a majority of direct democratic bills was not related to equality at all. Regarding the successful bills, we detect some regional differences along with the general tendency that there are more pro-than contra-equality bills. Our paper sheds new light on the question if direct democracy can serve as an appropriate means to complement representative democracy and to shape democratic institutions in the future. The potential of direct democracy in fostering or impeding equality should be an important criterion for the assessment of claims to extend decision-making by citizens.
