Autocracies and policy accumulation: the case of Singapore

The tendency of vote-seeking politicians to produce ever-more policies in response to the citizens’ demands has been identified as a central driver of the process of “policy accumulation.” If we accept this premise, policy accumulation should be a central feature of modern democracies but overall be less pronounced in autocracies. Due to its highly ambivalent nature, policy accumulation and its implications may thus constitute an important but so far neglected facets of the new system competition between democracies and autocracies. In this article, we test this argument in the context of the authoritarian regime of Singapore. Singapore is one of the very few autocracies that display elements of political competition and has a level of socio-economic development that is comparable to advanced democracies. Singapore thus constitutes a least-likely case for low levels of policy accumulation. By studying changes in Singapore’s environmental policy over a period of more than four decades (1976 to 2020) and by contrasting the patterns observed with the policy developments in 21 OECD democracies, we find that autocratic regimes do indeed tend to accumulate less than democratic regimes. More precisely, we find that Singapore (1) has only produced about one-fourth of the environmental policy measures of an “average” democracy and (2) is constantly the country with the lowest level of policy accumulation in our sample. These findings hold even when controlling for alternative explanations, such as the effectiveness of the administration and the government’s ability to opt for stricter and more hierarchical forms of intervention.
