We show that the sale of state-owned firms in dictatorships can help political corporations to emerge and persist over time. Using new data, we characterize Pinochet's privatizations in Chile and find that some firms were sold underpriced to politically connected buyers. These newly private firms benefited financially from the Pinochet regime. Once democracy arrived, they formed connections with the new government, financed political campaigns, and were more likely to appear in the Panama Papers. These findings reveal how dictatorships can influence young democracies using privatization reforms. © The Economic History Association 2020.

This article describes the design and manufacture of a gypsum board which, despite its 45 % wt content of phase change materials, meets the minimum physical and mechanical requirements laid down in the legislation on gypsum plasters (Spanish and European standard UNE EN 13279 and Spanish specifications for gypsum acceptance, RY 85). Under this design, a one-metre square, 1.5-cm thick board contains 4.75 kg of PCM, much more than in any prior drylining (the maximum attained to date is 3 kg per m2). The mechanical and physical characteristics of this new composite were previously improved with two joint-action additives: polypropylene fibres and melamine formaldehyde as a dispersing agent. In the 20-30 ºC temperature range, a gypsum board 1.5 cm thick containing this percentage of PCMs can store five times more thermal energy than conventional plasterboard of the same thickness, and the same amount of energy as half-foot hollow brick masonry. ; En esta investigación se ha diseñado y fabricado un panel de escayola que incorpora un 45% en peso de material de cambio de fase, manteniendo las propiedades físicas y mecánicas exigidas en la normativa de aplicación para yesos de construcción (UNE EN 13279 y referencias a la RY 85). Así, un panel de 1,0 m2 y 1,5 cm de espesor, contiene 4,75 kg de PCM, cantidad muy superior a la conseguida hasta la fecha (3 kg/m2). Para ello se ha mejorado previamente sus prestaciones mecánicas y físicas mediante adiciones binarias: fibras de polipropileno y dispersión de melanina formaldehído. Este porcentaje es capaz de almacenar en 1,5 cm de espesor cinco veces la energía térmica de un panel de cartón yeso con el mismo espesor y la misma cantidad que una fábrica de 1/2 pie de ladrillo hueco, en el rango de temperaturas próximas a la de confort (20-30 ºC).

AbstractWe exploit a fuel tax increase in Portugal to identify its effect on cross-border fuel sales and associated carbon leakage in the Spanish border regions. Using a difference-in-difference strategy, we find that while gasoline sales remained unaffected, diesel sales in Spanish border regions increased by 6–9%. Synthetic control methods confirm these estimates and attribute this differential effect by fuel type to routes frequented by heavy-duty vehicles, with large diesel tanks. We estimate a carbon leakage equivalent to 14–20% of Portugal's annual mitigation commitment for road transport emissions. Our findings imply that heavy goods vehicles' strategic behavior undermines the potential mitigation effects and revenue gains of transport climate policy, underscoring the need for coordinated policies in similar federal or quasi-federal contexts.

Introduction: To report the first
prospective case series of pediatric robotic urology
procedures in Latin America. Material and methods: A
prospective, descriptive, analytic study was performed of
all children who underwent robot-assisted pediatric urology
surgery (da Vinci system) from March 23, 2015 to April 20,
2016. Results: 38 robotic procedures were done in 30
patients. Mean age was 6.6 y (4 mo-15 yo). 20 males and 10
females. Weight range: 7.5 to 60 kg, height range: 55 to
180 cm. Eleven nephrectomies, 11 pyeloplasties, nine
ureteral reimplantations in six patients, four
varicocelectomies, one partial nephrectomy, one release of
ureteropelvic junction extrinsic obstruction were
performed. There was one postoperative complication (2.6%)
and one conversion (2.6%). Mean robotic console time (mean
= 150 min) and hospital stay (mean =2.5 days) were similar
to those reported in the literature. The mean follow up was
of seven months (1-13), with satisfactory evolution and no
mortality. Discussion: The present paper represents the
first pediatric case series in Mexico and Latin America.
Our results are satisfactory and reveal that pediatric
robotic urology procedures are feasible and safely
performed, similar to what has been previously reported in
the international literature.
