Welfare analysis of regulating mobile termination rates in the UK with an application to the Orange/T-Mobile merger

We present a calibrated model of the UK mobile telephony market with four mobile networks; calls to and from the fixed network; network-based price discrimination; and call externalities. Our results show that reducing mobile termination rates broadly in line with the recent European Commission Recommendation to either pure long-run incremental cost ; reciprocal termination charges with fixed networks; or Bill & Keep (i.e. zero termination rates), increases social welfare, consumer surplus and networks profits. Depending on the strength of call externalities, social welfare may increase by as much as £ 990 million to £ 4.5 billion per year, with Bill & Keep leading to the highest increase in welfare. We also apply the model to estimate the welfare effects of the 2010 merger between Orange and T-Mobile under different scenarios concerning MTRs, and predict that consumer surplus decreases strongly.

The politics of growth: Can lobbying raise growth and welfare?

This paper aims at analyzing the effects of lobbying over economic growth and primarily welfare. We model explicitly the interaction between policy-makers and firms in a setup where the latter undertakes political contributions to the former in exchange for more restrictive market regulations which induce exit and enhance the profitability of the market. In a sectorial equilibrium, despite stimulating growth, lobbying restricts the market structure and reduces welfare when compared to the free-entry outcome. However, once general equilibrium considerations are taken into account, we find that lobbying may improve welfare over a welfare maximizing free-entry equilibrium, by means of an expansion in aggregate demand. This introduces a new paradigm in the literature about the effects of lobbying over economic performance.

Baumol revisitado: Que futuro para o peso do sector da saúde em portugal?

A “Doença de Baumol” refere que o baixo crescimento da produtividade no sector da saúde e a uniformidade dos salários da economia como um todo, fazem com que os custos neste sector, dito “estagnado”, sejam inevitavelmente crescentes o longo do tempo. Este facto coloca uma pressão real acrescida na sustentabilidade dos Orçamentos de Estado na generalidade dos países desenvolvidos, que é difícil de resolver e para o qual se torna urgente desenvolver métodos de análise e solução eficazes. Concretamente, partindo de hipóteses cruciais, a fracção de despesa pública em saúde em Portugal, poderá atingir 9,5% do PIB já em 2010 e 20,9% do mesmo em 2030. Dado que não se põe a hipótese de conter custos baixando a qualidade dos cuidados médicos proporcionados pelo sector público, os dois caminhos mais plausíveis no curto prazo, são aumentar a eficiência ou incrementar o financiamento e provisão pelo sector privado e outras instituições de cariz social.
