We develop a unified cost-benefit framework that allows for a better understanding of nature conservation and climate policies under risk and uncertainty. We derive modified Hotelling rules from a social planner’s welfare optimization. They reveal four forces that jointly determine market...

Behavioral economics has so far largely avoided discussing the psychological origins of preferences, as well as their relation to needs. This has not only restricted interdisciplinary exchange, but also significantly limits the predictive capabilities of models. For example, the revealed...

The Deferred Acceptance (DA) algorithm is stable and strategy-proof, but can produce matchings that are Pareto-inefficient for students, and thus several alternatives have been proposed to correct this inefficiency that only involve consented priority violations. However, we show that these...

We consider welfare impacts of prohibitive tariffs on trading partners. Initially, there is prohibitive tariff by one country and a zero tariff by its trading partner. Thereafter, the trading partner also resorts to prohibitive tariff. We demonstrate how prohibitive tariffs by the trading...

We develop a unified cost-benefit framework that allows for a better understanding of nature conservation and climate policies under risk and uncertainty. We derive modified Hotelling rules from a social planner’s welfare optimization. They reveal four forces that jointly determine market...

Revealed preference theory (RPT) and its behavioral extension (BRPT) underpin an important strand of welfare economics. Their normative appeal rests on the claim that welfare can be inferred from observed behavior without substantive assumptions about what agents should value - a property I call...

The crises of both the climate and the biosphere are manifestations of the imbalance between human extractive, and polluting activities and the Earth's regenerative capacity. Planetary boundaries define limits for biophysical systems and processes that regulate the stability and life support...

A literature review is conducted of five recently developed methodologies to determine an optimal non-anthropocentric animal welfare levy that internalizes the social costs of animal suffering into the price of animal products, whereby animal and human welfare are counted equally. Chicken meat...

We review the evolution of the concept of utility in economics, addressing the conceptual and terminological fragmentation that characterises the interdisciplinary debate. This study adopts the scoping review framework to systematically analyse the main theoretical approaches, ranging from...

The well-known cooperative game solution core, with its strict stability requirement, provides no solution for non-balanced games. Subiza et al. (2025) relaxes the stability concept of the core and proposes δ-stable set, a non-empty solution for every essential TU-game. However, their approach...

Despite crowdfunding platforms' growing involvement in financing welfare, related ethical issues have received little scholarly attention. To address this gap, we focus on GoFundMe, the leading welfare crowdfunding platform in the US, to examine whether it facilitates the establishment of a just...

We establish the Subgradient Theorem for monotone correspondences -- a monotone correspondence is equal to the subdifferential of a potential if and only if it is conservative, i.e. its integral along a closed path vanishes irrespective of the selection from the correspondence along the path. We...

This paper characterizes a novel class of welfare criteria for settings with endogenous population. The core innovation is to treat parents’ fertility preferences as ethically relevant, deferring to them on the quality--quantity trade-off under conditions of equality. The resulting family of...

Welfare economics relies on access to agents' utility functions: we revisit classical questions in welfare economics, assuming access to data on agents' past choices instead of their utilities. Our main result considers the existence of utilities that render a given allocation Pareto optimal. We...

We reappraise the Arrow problem by studying the aggregation of choice functions. We do so in the general framework of judgment aggregation, in which choice functions are naturally representable by specifying, for each menu A and each alternative x in A, whether x is choosable from A, or not. Our...
