Denis Hilton : Incentivizing environmentally responsible behaviour : Nudges and green fiscal systems.

Policy-makers have a range of options available to regulate “green” consumer behaviour (e.g., eco-labels, carbon footprint information, descriptive and injunctive norms, fiscal systems, laws, or some combination of these) but little guidance in how to choose between these options. We aim to provide a common behavioural framework for understanding the separate and combined effects of these regulatory systems. We illustrate our approach using findings about the impact of different kinds of eco-labels and nudges in realistic incentivized online shopping platforms. We then show, using survey methodology in the transport domain, that some fiscal measures may influence purchase intentions through both prices and injunctive social norms, and that these effects are independent and additive. However, an overly high financial incentive may have paradoxical effects.

Alan Lewis : Attitudes to tax evasion and benefit fraud: U.K and Italy compared.

In neo-classical economics the decision to evade tax is analysed in the same way as the decision to commit benefit fraud as both decisions depend on the net expected utility that a ‘representative individual’ will derive from the gamble. If the financial loss that a community experiences when there is tax evasion is equal to the financial loss experienced when there is benefit fraud there is no reason to expect differences in individuals’ attitudes toward these crimes. However replies to questionnaires show respondents are more condemnatory of benefit fraud than tax evasion (Cullis, Jones, Lewis, Castiglioni and Lozza, 2015).
The present study presents novel data from among samples of undergraduate students in the U.K. (n=127) and Italy (n=122). The questionnaire investigates whether the seriousness of the two crimes are similar, whether respondents themselves would evade taxes or engage in benefit fraud and what they believe the appropriate punishments should be. Cultural differences are also explored between the two countries where both tax evasion and benefit fraud are more common in Italy; does this mean that Italian respondents will be more tolerant ?
