Despite the growing importance of the digital sector, research on economic complexity and its implications continues to rely mostly on administrative records—e.g. data on exports, patents, and employment—that have blind spots when it comes to the digital economy. In this paper we use data on the...

This paper provides an assessment of the 2019 minimum-wage hike in Spain, which increased the minimum wage by 22 % and directly concerned 7 % of dependent employees. We make use of two complementary approaches, one that follows incumbent workers over time and hence does not take account of any...

We empirically study whether carbon emissions affect firms’ cost of capital raised on conventional bond markets. We find that firms with higher carbon emissions face higher spreads in the secondary market but not in the primary market. We show that this gap is related to uncertainty about climate...

Compositional Data (CoDa) is usually viewed as data on the simplex and is studied via a log-ratio analysis, following the classical work of Aitchison (1986). We propose to bring to the fore an alternative view of CoDa as a stick breaking process, an approach which originates from Bayesian...

We study a situation where physicians differing in their degree of altruism exert a diagnostic effort before deciding whether to test patients to determine the most appropriate treatment. The diagnostic effort generates an imperfect private signal of the patient’s type, while the test is perfect....

This paper analyzes the effect of longevity on parenting choices from a life course perspective. We develop an overlapping generations model to address a core tradeoff that young parents face when investing in their children’s human capital. They can choose a low-time-cost demanding strategy that...

The European Union designates 26% of its landmass as protected areas, limiting economic development for biodiversity. We use the staggered introduction of protected areas between 1985 and 2019 to study the selection of protected land and the causal eect of protection on vegetation cover and...

We first show a simple but striking result in bilevel optimization: unconstrained smooth bilevel programming is as hard as general extended-real-valued lower semicontinuous minimization. We then proceed to a worst-case analysis of box-constrained bilevel polynomial optimization. We show in...

Consider the global optimisation of a function defined on a finite set endowed with an irreducible and reversible Markov generator. By integration, we extend to the set of probability distributions on and we penalize it with a time-dependent generalized entropy functional. Endowing with a Maas’...
