We propose a novel approach for causal mediation analysis based on changes-in-changes assumptions restricting unobserved heterogeneity over time. This allows disentangling the causal effect of a binary treatment on a continuous outcome into an indirect effect operating through a binary...

We study the impact of fiscal revenue shocks on local fiscal policy. We focus on the very volatile revenues from the immovable property gains tax in the canton of Zurich, Switzerland, and analyze fiscal behavior following large and rare positive and negative revenue shocks. We apply causal...

This paper proposes a difference-in-differences approach for disentangling a total treatment effect on some outcome into a direct impact as well as an indirect effect operating through a binary intermediate variable – or mediator – within strata defined upon how the mediator reacts to the...

This paper evaluates the effect of a voucher award system for assignment into vocational training on the employment outcomes of unemployed voucher recipients in Germany, along with the causal mechanisms through which it operates. It assesses the direct effect of voucher assignment net of actual...

The ability of voters to use the available electoral instruments is crucial for the functioning of democracies. The paper shows that voters consider the institutional environment when making electoral decisions. Voters recognize that executives who face binding term limits (i.e., lame ducks)...

We aim to estimate the elasticity of voter turnout. We analyze how voters react to a change in voting costs. Some municipalities in the canton of Berne reduced voting costs by paying the postage of the return envelope when voters opt for postal voting. We find that paying the postage is...

In this paper, we present and illustrate novel data on more than a century of regulation in Switzerland. We provide quantitative measures for Swiss cantons on the annual stock of legally binding rules from 2006-2013 and on regulatory activity as reflected in the annual changes to such regulation...

We study the impact of a one-off exogenous fiscal windfall on local public finances in the canton of Zurich in Switzerland. The windfall was due to the IPO of Glencore on the London Stock Exchange in 2011. As a result, its CEO paid an extraordinary tax bill of approximately CHF 360 million....

Public auditors should reduce agency problems and improve transparency. We address the question of whether auditors should be elected by the citizens or appointed by either the legislature or the executive, and explore the influence of conducting performance audits. We construct a unique dataset...

Corporate auditors review and evaluate financial statements. To enhance independence the selection process and mandatory auditor rotation requirements have been debated intensively. The available empirical evidence is not conclusive and suffers from serious endogeneity problems. We propose...
