Fixed-mobile integration

Often, fixed-line incumbents also own the largest mobile network. We consider the effect of this joint ownership on market outcomes. Our model predicts that while fixed-to-mobile call prices to the integrated mobile network are more efficient than under separation, those to rival mobile networks are distorted upwards, amplifying any incumbency advantage. As concerns potential remedies, a uniform off-net pricing constraint leads to higher welfare than functional separation and even allows to maintain some of the efficiency gains.

The effects of land-use development policies on forest management

This paper develops a model of a forest owner operating in an open-city environment, where the rent for developed land is increasing concave in nearby preserved open space and is rising over time reflecting an upward trend in households’ income. Thus, our model creates the possibility of switching from forestry to residential use at some point in the future. In addition it allows the optimal harvest length to vary over time even if stumpage prices and regeneration costs remain constant. Within this framework we examine how adjacent preserved open space and alternative development constraints affect the private landowner´s decisions. We find that in the presence of rising income, preserved open space hastens regeneration and conversion cuts but leads to lower density development of nearby unzoned parcels due to indirect dynamic effects. We also find that both a binding development moratorium and a binding minimum-lot-size policy can postpone regeneration and conversion cut dates and thus help to protect open space even if only temporarily. However, the policies do not have the same effects on development density of converted forestland. While the former leads to high-density development, the latter encourages low-density development.

António Manuel Pinto Barbosa, economista e governante

António Manuel Pinto Barbosa (1917-2006), incluído entre os “Cem portugueses que moldaram o século XX” no Expresso Revista foi biografado por João César das Neves e Francisco Azevedo e Silva num livro publicado em 1999, cujo capítulo 7 o intitula “Decano dos economistas”. A sua actividade na Faculdade de Economia da Universidade Nova de Lisboa, que fundou em 1978 e onde foi homenageado em 1989, e sobretudo na Academia das Ciências de Lisboa foram porém menosprezadas nesse trabalho. Este elogio tenta reparar a falha, focando ainda o problema dos desequilíbrios da balança de pagamentos que tanto o preocuparam na Europa e no mundo, na medida em que interagem perigosamente com os desequilíbrios orçamentais, hipotecando a riqueza das nações. Aos complementos de texto acrescem anexos com referências e trabalhos consultados, o processo individual na Academia e contribuições recentes para a análise dos desequilíbrios externos na Zona Euro no espírito de Pentti Kouri (1949-2009).

António Manuel Pinto Barbosa (1917-2006), economista e governante, foi incluído pelo Expresso Revista entre os “Cem portugueses que moldaram o século XX”. Biografado por João César das Neves e Francisco Azevedo e Silva num livro publicado em 1999, cujo capítulo 7 o intitula “Decano dos economistas”, mas a sua actividade na Faculdade de Economia da Universidade Nova de Lisboa, que fundou em 1978 e onde foi homenageado em 1989, e sobretudo na Academia das Ciências de Lisboa, é menos conhecida. Este escrito tenta reparar a falha e foca ainda o problema dos desequilíbrios da balança de pagamentos na Europa e no mundo que tanto o preocuparam, na medida em que interagem perigosamente com os desequilíbrios orçamentais, hipotecando a riqueza das nações. Inclui o elogio pronunciado em sessão conjunta da Academia das Ciências de Lisboa, 14/11/13 (cadeira nº 18L), o discurso de aceitação por Pedro Soares Martínez, decano da secção de direito e ciência política da Academia (cadeira 11L), pronunciado na mesma sessão, e um testemunho de Manuel Jacinto Nunes, que sucedeu a Pinto Barbosa enquanto decano dos economistas portugueses e da secção de economia e finanças da Academia (cadeira 8L), mas não estava na sessão. Seguem-se complementos incluíndo excertos duma análise dos desequilíbrios externos na Zona Euro no espírito de Pentti Kouri (1949-2009).

Referenda outcomes and the influence of polls: A social network feedback process

This paper proposes a model to explain the differences between outcomes of referenda and the voting trends suggested by polls. Two main effects are at stake. First, the evolution of the voters' attitudes is conditional on the public information made available to them. Second, the predisposition toward abstention among individuals within each voting group may be different. Our model describes how these two aspects of decision making may interact, showing how publicly available information may amplify the distinct tendency toward abstention between both groups and thus affect the outcome of the referendum.
