This result suggests that more inclusive governance through direct decision-making mechanisms may induce more accountable and less inefficient governments. Direct Democracy and Local Government Efficiency

Taxpayer nudges-behavioral interventions that aim to increase tax compliance without changing the underlying economic incentives of taxpayers-are used increasingly by governments because of their potential cost-effectiveness in raising tax revenue. We collect about a thousand treatment effect estimates from over 40 randomized controlled trials, and in a meta-analytical framework show that non-deterrence nudges-interventions pointing to elements of individual tax morale-are on average ineffective in curbing tax evasion, while deterrence nudges-interventions emphasizing traditional determinants of compliance such as audit probabilities and penalty rates-are potent catalysts of compliance. These effects are, however, fairly small in magnitude. Deterrence nudges increase the probability of compliance by only 1.5-2.5 percentage points more than non-deterrence nudges, while the effects are likely to be bound to the short-run, and are somewhat inflated by selective reporting of results.

Recent theoretical research suggests that financing sub-national governments' expenditure out of own revenue sources is linked to more responsible budgeting, because the financial implications of spending decisions then are internalized within a jurisdiction. We test this proposition empirically on a sample of 23 OECD countries over the 1975-2000 period, and find evidence in line with the hypothesis that greater revenue decentralization (measured as sub-national governments' share of own source tax revenues in general government tax revenue) is associated with improved sub-national government budget deficits/surpluses. This finding is cross-validated with a novel, independent dataset consisting of all 34 OECD member states from 2002 to 2008.
