In this paper, we develop and numerically solve a model of idiosyncratic labour income and idiosyncratic interest rates to predict the evolution of a wealth distribution over time. Stochastic labour income follows a deterministic growth trend and it fluctuates between a wage and unemployment...

In the absence of first-best climate policy, we demonstrate that existing government institutions and policy established for reasons unrelated to climate change may induce climate adaptation. We examine the impact of temperature on ambient ozone concentration in the United States from 1980-2013,...

Assuming a two-period model with endogenous choices of labour, education, and saving, it is shown to be second-best efficient not to distort the choice of education. In general this implies distorting the saving decision. Hence a strict order of policy priority is derived. Efficient tax policy...

We examine the second-best family policy under the assumption that both the number and the future earning capacities of the children born to a couple are random variables with probability distributions conditional on unobservable parental actions. Potential parents take their decisions without...

As credit and insurance markets are imperfect, and given that intra-family transfers, and the way a child uses her time outside school hours, are private information, the second-best policy makes school enrollment compulsory, forces overt child labour below its efficient level (if positive), and...

The debate on the immigration policies in OECD countries has turned its attention towards illegal migrants. Given that migration flows are determined by immigration laws, the probability of potential detection, penalties for unauthorised migrants and their employers, and on income differences...

We study the interactions between capital income tax and social security privatization in the context of rising longevity. In an economy with idiosyncratic income shocks, redistributive defined benefit social security provides some insurance against income uncertainty. This insurance comes at...

We study the optimal tax system when taxpayers earn different kinds of income by supplying different inputs. Imperfect substitution between inputs allows for general equilibrium effects. We consider any type of cross-base responses to tax changes such as income-shifting. Formalizing the tax...

This paper presents a comprehensive analysis of the role of capital taxation in advanced economies with a focus on the Swedish experience. We synthesize the existing theoretical literature, present facts about the capital stock and its distribution, review current capital tax practices and...

We theoretically express the Laffer tax rate on capital income as a function of the elasticities of capital income (the "direct" elasticity) and of labor income (the "cross" elasticity) with respect to the net-of-tax rate on capital income. We estimate these elasticities using salient capital...
