Austerity plans and tax evasion : theory and evidence from Greece

The unprecedented tax hikes implemented in Greece in 2010 generated a much lower than expected increase in tax revenues. In this paper, we document a new stylized fact explaining this gap: the strong increase of tax evasion. We then analyze the response of the economy to tax hikes in a stylized model where firms adjust the share of their declared activity. We calibrate the model to firm-level balance sheet data for Greece and quantify the response of tax evasion to the 2010 fiscal adjustment. One third of the tax increase is lost because small and medium size firms expand their share of non-declared activity. In turn, this lowers their borrowing capacity and contributes to non-negligible output losses.

Rare Events and Risk Perception: Evidence from Fukushima Accident

We study changes in nuclear-risk perception following the Fukushima nuclear accident of March 2011. Using an exhaustive registry of individual housing transactions in England and Wales between 2007 and 2014, we implement a difference-in-difference strategy and compare housing prices in at-risk areas to areas further away from nuclear sites before and after Fukushima incident. We find a persistent price malus of about 3.5% in response to the Fukushima accident for properties close to nuclear plants. We show evidence that this price malus can be interpreted as a change in nuclear-risk perception. In addition, the price decrease is much larger for high-value properties within neighborhoods, and deprived zones in at-risk areas are more responsive to the accident. We discuss various theoretical channels that could explain these results.
