Imperfect Bayesians: A Process Model and Evidence from Response Times
People are not Bayesians. Or are they? This work discusses a simple process model of faulty decision making where deliberative processes standing in for Bayesian updating compete with simpler heuristics, resulting in predictable error and response-time patterns. The predictions are then tested in a decision-making experiment on belief updating where opposite biases can occur, representativeness (overweighting the sample information due to stereotypical appearances) and conservatism (overweighting the prior).

Environmental Tax Reform under debt constraint
This article analyzes the impacts of Environmental Tax Reform (ETR) when the government is constrained not to increase the public debt-to-output ratio. We consider an
overlapping generations model with pollution. Public spending for pollution abatement are …nanced by tax revenues and public debt. We show that keeping constant the public
debt-output ratio is not an obstacle to attain a double dividend, i.e. an increase of both (i) environmental quality and (ii) aggregate consumption. First, if the capital stock is
low and the pollution abatement is large enough, a successful ETR consists in a rise of the environmental tax, compensated by a decrease of the income tax. Secondly, we show
that the environmental tax revenues may help reduce the public debt-output ratio. We give conditions (on the initial level of the environmental tax and the debt-output ratio)
such that an increase of the environmental tax, budget-balanced by a decrease of the debt-output ratio may also achieve a double dividend. We conclude that public debt crisis
should not compromise ETR, instead, environmental tax revenues could be part of the solution.
