Giovanni B. Concu, Claudio Detotto, Marco Vannini (18/01/2021), Drivers of intentions and drivers of actions: willingness toparticipate versus actual participation in fire management inSardinia, Italy
Changing wildfire regimes coupled with budget cuts are spurring increased involvement of communities and citizens in fire management programs. Policy making faces the task of understanding citizens’ willingness to participate and mobilizing will into actions. As there is no reason to expect that the same factors affect willingness to participate and actual participation in the same direction, policy making would require information both on citizens’ preferences over management programs and on drivers and barriers to adoption. In this paper we compare data on preferences from a latent class Discrete Choice Experiment (DCE) with data on adoption of fire prevention and mitigation measures. The objective is to test if the same factors explain actual participation and willingness to participate in fire management programs. Results suggest that sufficient information for policy design cannot be gained exclusively from the DCE or the analysis of actual behavioural data as the sets of explanatory factors do not entirely overlap. However, two variables – knowledge of fire prescriptions and community’s capacity – can be used to influence both the adoption of prevention and mitigation measures and citizens’ willingness to participate in fire management. Policy makers can directly control these factors to nudge the public towards greater involvement in fire prevention and mitigation.

Georges Casamatta (24/06/2020), Optimal income taxation with tax avoidance and endogenous labor supply
We determine the optimal income tax schedule when individuals both determine endogenously their labor supply and have the possibility of avoiding paying taxes. Considering a convex concealment cost function, we propose a formula for the optimal marginal tax rate, that generalizes the standard Mirrlees formula to the case of tax avoidance. We also show that the results obtained by (2020) in the fixed income case hold true when labor supply is endogenous: with a low enough marginal cost of avoidance, part of the taxpayers, located in the interior of the skill distribution, optimally choose to avoid taxes.
Keywords: tax avoidance, optimal income taxation.
Georges Casamatta (18/05/2020), Optimal bequests taxation in the steady state
We consider an infinite-horizon economy populated by two types of individuals, some individuals being more productive than others. Individuals live one period and are altruistic toward their children. Assuming that the allocation received by a given individual depends only on his type and the one of his parent, we first determine the second-best steady state allocation and then study the optimal bequest and labor income tax functions, that are assumed to be separable. We first show that the second-best is not implementable with such tax schedules. We then demonstrate that it may be desirable to tax large bequests (and to subsidize low bequests), provided that individuals are sufficiently altruistic and the less productive individuals are sufficiently numerous. The taxation of large bequests is however not always part of the optimal solution. A numerical example suggests that no taxation of bequests is needed under moderate altruism, while large bequests should be subsidized when individuals are poorly altruistic.
Keywords: bequests, taxation, steady state.

Georges Casamatta (04/05/2020), Optimal income taxation with tax avoidance
We determine the optimal income tax schedule when individuals have the possibility of avoiding paying taxes. Considering a convex concealment cost function, we find that a subset of individuals, located in the interior of the income distribution, should be allowed to avoid taxes, provided that the marginal cost of avoiding the first euro is sufficiently small. This contrasts with the results of Grochulski (2007) who shows that, with a subadditive cost function, all individuals should declare their true income. We also provide a characterization of the optimal income tax curve.
Keywords: fiscal avoidance, optimal income tax.

Yuheng Ling, Claudio Detotto, Dominique Prunetti (03/02/2020), Spatio-Temporal Modeling of second homes dynamics in Corsica
Second home development is an important issue to a housing market and local land use. Understanding second home dynamics at the small area scale will help pol- icymakers to conduct effective interventions to meet the concern of local inhabitants. Conventional approaches do not consider second homes varied across space and over time. Hence, spatial models, such as the Besag, York and Mollie (BYM) model, are useful in terms of offering a feasible way to model both covariates and spatial, temporal dependence. This tool is then applied to analyse the second home ratio at a county level in Corsica, France, over the period 2007-2016. We intend to investigate the impact of spatially referenced covariates and the spatio-temporal dependencies of the second home ratio in each Corsican county. Binomial regression models with spatial and tem- poral random effects are implemented via Integrated Nested Laplace Approximations pertaining to a Bayesian paradigm. Results show that the model with spatial, temporal random components and a spatiotemporal interaction term produces the most realistic estimates and the best forecast. Then, physical landscape counts, coastal counties, and mountainous counties are positively associated with second home rates, while cultural landscape counts, number of households and interest rates are negatively associated with the second home rates. We also identify the “hot spot” and “cold spot” of the sec- ond homes. While the temporally structured component reveals that there was merely a gradual increase on the second home ratio over the past 10 years.
