All but one free ride when wealth effects are small
Joaquim Silvestre
SERIEs , 2012, DOI: 10.1007/s13209-011-0057-4
Abstract: Quasilinear preferences on a public good and a numeraire good are limits of preferences where both goods are normal. The set of equilibria of the voluntary contribution (or private provision) game is easily characterized under quasilinearity by: top valuators aggregately contribute their common stand-alone contribution, whereas non-top valuators contribute nothing. Because, as long as preferences are randomly selected, there will typically be a single top valuator, it follows that, typically, the equilibrium is unique, with all players but one contributing nothing, hence “free riding” in the sense of the ordinary English usage of the expression. The upper-hemicontinuity of the Nash equilibrium correspondence implies that this is also the case when both goods are strictly normal, but the wealth effects on the public good are small.

Abstract: background: endemic pemphigus foliaceus is an autoimmune, cutaneous and bullous disease, most incident in the midwest of brazil and with a lower incidence in some south-american countries. although its autoimune character has been demonstrated by the presence of autoantibodies and by the importance of genetic predisposition, the environmental factors that trigger the disease have not been clearly established yet. objectives: to know the distribution of the disease in the state of goias, and its social and demographic characteristics. methods: two hundred and ten patient records with an established diagnosis from the period between 1996 and 2001 were analyzed. demographical information was correlated with the state population, and the incidence of the disease was determined for each of its microregions. results: a higher incidence of the disease was observed in the rural areas, among patients in the third decade of life, with a slight familiar occurrence and with no gender preference. the largest contingent (74.3%) of patients came from the state of goiás, and the greatest incidences occurred in the microregions of anicuns, chapada dos veadeiros, rio vermelho, vale do rio dos bois, iporá e aragar?as. conclusions: there was a prevalence of the disease in the third decade of life and in those individuals who lived or worked in rural areas. disease concentration areas were detected, through calculation of an incidence coefficient, in some of the microregions, especially in the central area of the state of goiás. further research is necessary to clarify the reasons for this ecological concentration.
Desemprego tecnológico: Ricardo, Marx e o caso da indústria de transforma??o Brasileira (1990-2007)

Abstract: the issue of technological unemployment was a cause for concern for two of the greatest thinkers in the field of economic science: david ricardo and karl marx. both believed that the introduction of new machines could bring about chronic unemployment for a certain period of time. however, this was only a possibility that had already taken place within english industrial capitalism, but that could be avoid if new investments absorbed the workforce laid off by the introduction of new machinery. in the case of brazil, the country underwent a restructuring period of its industrial base during the 1990s, which according to the methodology employed in our study, verified the existence of the technological unemployment phenomenon during much of the aforementioned decade.
