Sobre Glauconia gaudryi (Vilanova, 1868), gasterópodo del Hauteriviense

En 1868, VILANOVA creó la especie Vicarya gaudryi, que fue considerada sinónima de Muricites strombiformis por MALLADA (1887) y autores posteriores. De acuerdo con todas sus características debe anularse esta sinonimia, redescribiéndose Glauconia gaudryi del Hauteriviense inferior de Mirambel (Prov. Teruel). Se considera propia de un ambiente deltaico

How to achieve full electrification: Lessons from Latin America

Electricity coverage in Latin America has increased substantially in recent decades, rising from 50% of the population in 1970 to more than 95% in 2015. Growth, however, slowed in the 1990s as many countries experienced difficulties in extending their networks further, in particular to serve those living in isolated and rural areas. In spite of this, the process of electrification was not interrupted and at the beginning of the 2010s decade most countries in the region were able to provide access to electricity to almost all of their populations. In this paper, we examine the main strategies used in Latin America to increase coverage and argue that only a combination of policy efforts has made it possible to achieve the current situation. We also examine the remaining obstacles, at policy and institutional levels, to achieving full coverage

Platform price parity clauses and market segmentation

Price parity clauses (PPCs) are widely adopted by online platforms to force client sellers not to lower their prices elsewhere. We investigate under what conditions online travel agencies (OTAs) decide to apply PPCs, and how this affects hotels' listing decisions on OTAs. We find OTAs adopt PPCs when there is a sufficiently large competitive pressure in the market, either between OTAs, or between hotels (or both). PPCs allow OTAs to charge higher commission fees to hotels, which can respond by delisting from certain OTAs, thereby segmenting the market. We also find that consumers and hotels generally lose out with PPCs
