We propose a formal description of individual preferences that captures a subsistence requirement in consumption in an otherwise standard constant-elasticity-ofsubstitution (CES) utility specification. We study how substitutability between the subsistence good and another good depends on the...

We argue that economics – as the scientific method of analyzing trade-offs – can be helpful (and may even be indispensable) for assessing the trade-off between intergenerational and intragenerational justice. Economic analysis can delineate the “opportunity set” of politics with respect...

Commercial cattle farming in Namibia, a prime example of livestock farming in semi-arid rangelands, is subject to a variety of risks, predominant among which is precipitation risk. At the same time it suffers from rangeland degradation that is at least partly due to inadequate management. We...

We study how society's preferences affect the resilience of economies that depend on more than one type of natural resource. In particular, we analyze whether the degree of complementarity of natural resources in consumer preferences may give rise to multiple steady states and path dependence...

Most ecosystem services, which are essential for human well-being, are globally declining, while the production of consumption goods, measured by GDP, is still growing. To adequately account for this opposite development in public cost-benefit analyses, it has been proposed - based on a...

We develop and formalize a utilitarian notion of responsibility for sustainability which is inspired by Singer's (1972) principle and the Brundtland Commission?s notion of sustainability (WCED 1987). We relate this notion of responsibility to established criteria for the assessment of...

We study the regulation of a morally responsible agent in the context of a negative consumption externality and motivation crowding. In particular, we analyze how various governmental interventions affect the agent’s motivation to assume moral responsibility. Employing a motivation-crowding...

We propose a new three-step model-selection framework for size distributions in empirical data. It generalizes a recent frequentist plausibility-of-fit analysis (Step 1) and combines it with a relative ranking based on the Bayesian Akaike Information Criterion (Step 2). We enhance these...

We study the effectiveness of costly rewards in mitigating excess extraction in a standard Common Pool Resource (CPR) game experiment. We implement two treatments. In the first, rewards are a pure transfer from one player to the other. In the second, the benefits of receiving a reward are higher...
