This paper explores one option for the development of a theoretical approach to economic decision-making that goes beyond the mechanical-mathematical models based on the assumptions of rational self-interest and utility maximization. The proposed model incorporates facts, values, relationships,...

To avoid the dangerous consequences of climate change, humans need to overcome two intertwined conflicts. First, they have to deal with an intra-generational conflict that emerges from the allocation of costs of climate change mitigation among different actors of the current generation. Second,...

We show that on-demand insurance contracts, an innovative form of coverage recently introduced through the InsurTech sector, can serve as a screening device. To this end, we develop a new adverse selection model consistent with Wilson (1977), Miyazaki (1977) and Spence (1978). Consumers have...

This paper presents two arguments in favor of the sole use of an income tax for redistribution purposes. The first is that most findings on nonlinear commodity taxation such as Mirrlees's formulae for Pareto efficiency, Seade's results on zero tax rates at the endpoints of the scale, and the...

The government often provides relief against large risks, such as disasters. A simple, general rationale for this role of government is considered here that applies even when private contracting to share risks is not subject to market imperfections. Specifically, the optimal private sharing of...

A method for handling monotonicity constraints in optimal control problems is applied in order to correct a technical weakness of optimal nonlinear taxation models with many commodities, caused by the neglect of a second order constraint for utility maximization. We conclude that all the optimal...

The standard model on optimal income taxation in the presence of tax evasion is extended to allow for mobility between the legal and hidden sectors. The conclusions from the traditional analysis of tax evasion strongly contrast with those that result when extensive margin responses are taken...
