We revisit Hawkins’ (Comput Stat 9(3):233–247, <CitationRef CitationID="CR15">1994</CitationRef>) algorithm for fitting monotonic polynomials and discuss some practical issues that we encountered using this algorithm, for example when fitting high degree polynomials or situations with a sparse design matrix but multiple observations...</citationref>

We show that both parametric distribution functions appearing in extreme value theory have log-concave densities if the extreme value index [gamma][set membership, variant][-1,0] and that all distribution functions F with log-concave density belong to the max-domain of attraction of the...

In this paper we present the weighted least squares estimator for the extreme value index, and prove its consistency and asymptotic normality.

We provide critical notes to the paper by Kallis et al. (2013) on monetary valuation. We evaluate the four criteria they propose for assessing valuation studies. We argue that no clear distinction is made between monetary valuation and pricing instruments. The selected criteria are more relevant...

An agreement on climate change mitigation hinges on large-scale international cooperation. Rational agents are supposed to consider the cost and benefits of cooperation, which then determine their negotiation positions. Behavioral economics provides experimental evidence that decision-making in...
