We consider a world economy, in which the global public good "biodiversity" is positively correlated with that share of land which is protected by land-use restrictions against the deterioration of habitats and ecosystems. The willingness-to-pay for biodiversity conservation is positive in...

The European Union designates 26% of its landmass as a protected area, limiting economic development to favor biodiversity. This paper uses the staggered introduction of protected-area policies between 1985 and 2020 to study the selection of land for protection and the causal effect of...

This paper analyzes nature protection by a social planner under different "utilitarian" social welfare functions. For that purpose we construct an integrated model of the economy and the ecosystem with explicit consideration of nonhuman species and with competition between human and nonhuman...

In an integrated economy-ecosystem model humans choose their land use and leave the residual land as habitat for three species forming a food chain. The size of habitat determines the diversity and abundance of species. That biodiversity generates, in turn, a flow of ecosystem services with...

NGO aid is still widely believed to be superior to official aid (ODA). However, the incentives of NGOs to excel and target aid to the poor and deserving are increasingly disputed. We contribute to the emerging literature on the allocation of NGO aid by performing panel Tobit estimations for...

We use Swiss data to test whether intergenerational educational mobility is affected by the age at which children first enter (primary) school. Early age at school entry significantly affects mobility and reduces the relative advantage of children of better educated parents. -- Age at entry ;...

This paper presents the results of a randomized experiment analyzing the use of vouchers for adult training. In 2006, 2,400 people were issued with a training voucher which they were entitled to use in payment for a training course of their choice. User behavior was compared with a control group...

This paper studies the role of culture in shaping unemployment outcomes. The empirical analysis is based on local comparisons across a language barrier in Switzerland. This Röstigraben separates cultural groups, but neither labor markets nor political jurisdictions. Local contrasts across the...

Behavioral economics documents the importance of status and self-image concerns in the workplace, but is largely silent about how to instrumentalize them to induce effort. Awards - widespread in the corporate sector and elsewhere - are motivators that derive their value from such social...
