The paper contrasts empirically the results of alternative methods for estimating the value and the depreciation of mineral resources. The historical data of Mexico and Venezuela, covering the period 1920s-1980s, is used to contrast the results of several methods. These are the present value,...

We study the determinants of comparative advantage in polluting industries. We combine data on environmental policy at the country level with data on pollution intensity at the industry level to show that countries with laxer environmental regulation have a comparative advantage in polluting...

We study the effects of the cancellation of a sizeable child benefit in Spain on birth timing and neonatal health. In May 2010, the government announced that a 2,500-euro universal "baby bonus" would stop being paid to babies born starting January 1, 2011. We use detailed micro data from birth...

This paper provides empirical evidence on the explanatory factors affecting introductory prices of new pharmaceuticals in a heavily regulated and highly subsidized market. We collect a data set consisting of all new chemical entities launched in Spain between 1997 and 2005, and model launching...

In this paper we attempt to describe the general reasons behind the world population explosion in the 20th century. The size of the population at the end of the century in question, deemed excessive by some, was a consequence of a dramatic improvement in life expectancies, attributable, in turn,...

This paper studies two important reasons why people violate procedure invariance, loss aversion and scale compatibility. The paper extends previous research on loss aversion and scale compatibility by studying loss aversion and scale compatibility simultaneously, by looking at a new decision...

Informal care is today the form of support most commonly used by those who need other people in order to carry out certain activities that are considered basic (eating, dressing, taking a shower, etc.), in Spain and in most other countries in the region. The possible labour opportunity costs...

This paper studies oligopolistic competition in off-patent pharmaceutical markets using a vertical product differentiation model. This model can explain the observation that countries with stronger regulations have smaller generic market shares. It can also explain the differences in observed...

This paper analyzes the nature of health care provider choice in the case of patient-initiated contacts, with special reference to a National Health Service setting, where monetary prices are zero and general practitioners act as gatekeepers to publicly financed specialized care. We focus our...

This paper tests the internal consistency of time trade-off utilities. We find significant violations of consistency in the direction predicted by loss aversion. The violations disappear for higher gauge durations. We show that loss aversion can also explain that for short gauge durations time...
