Abandon ship? : party brands and politicians’ responses to a political scandal

Daniele, Gianmarco ; Galletta, Sergio ; Geys, Benny

In this article, we study politicians’ – rather than voters’ – responses to the main political scandal in Italian recent history (Tangentopoli), and overcome endogeneity concerns by analysing the local implications of this national corruption scandal. We find that local politicians withdraw support for incumbents in parties hit by Tangentopoli – inducing increased political...

Popularity shocks and political selection : the effects of anti-corruption audits on candidates quality

Cavalcanti, Francisco ; Daniele, Gianmarco ; Galletta, Sergio

We show that the disclosure of information about a government's conduct affects the types of candidates who stand for election. Our empirical test focuses on Brazilian city council elections in 2004 and 2008. The identification strategy exploits the randomness of the timing of the release of audit reports on the (mis)use of federal funds by local governments. We observe that when the audit...

In this paper, I empirically investigate the presence of spillover effects resulting from the strengthening of law enforcement against corruption and organized crime in local governments. Specifically, I take advantage of an Italian law that gives power to the central government to replace democratically elected municipal officials who are potentially connected with mafia with a commission of...

Direct democracy, partial decentralization and voter information : evidence from Swiss municipalities

Galletta, Sergio

In this paper I investigate whether changes in the availability of direct democratic institutions in local Swiss jurisdictions affect expenditure decentralization. By using a panel-based difference in differences estimation I find a statistically significant reduction in decentralization when the mandatory fiscal referendum is introduced at the local level. This result is consistent with the...

Highway to economic growth? : Competition in public works tenders in the Democratic Republic of Congo

Galletta, Sergio ; Jametti, Mario ; Redonda, Agustin

The Democratic Republic of Congo (DRC) is one of the poorest countries in the World. The construction sector will play an essential part to bring the country on the path of economic growth, and competition within the sector is crucial to achieve this goal. In this paper we analyze the effect of competition in public works tenders in the DRC. Using a unique and newly assembled database on...

How to tame two leviathans? : Revisiting the effect of direct democracy on local public expenditure

Galletta, Sergio ; Jametti, Mario

We explore how the vertical structure of direct democracy in a federal context affects expenditure decisions of sub-central governments. In so doing we revisit previous research on the effect of direct democratic institution on public policies. Particularly, the effect of upper-level (state) existence of direct democratic control on local expenditure. Empirically we exploit the fact that both...
