Financial Constraints: Do They Matter to R&D Subsidy Attribution?
Silva, Filipe; Carreira, CarlosEven though innovation subsidies and financial constraints are two closely related lines of research, the link between them is rather unexplored. This paper is, to our knowledge, the first to explicitly analyse both the allocation of innovation subsidies and their role in alleviating firms’ financial constraints. It is not the purpose of the paper to question whether subsidies foster innovation, but rather if: ...
Educação para o desenvolvimento: a educação como via para a erradicação da pobreza
Carreira, CarlosA Declaração do Milénio das Nações Unidas, aprovada na Cimeira do Milénio, reflectindo as preocupações de 147 Chefes de Estado e de Governo e de 191 países, que participaram na maior reunião de sempre de dirigentes mundiais, definiu alvos concretos no domínio do desenvolvimento, como reduzir para metade a percentagem de pessoas que vivem na pobreza extrema e fornecer água potável e educação a todos. Na senda de...
No Deep Pockets: Some stylized results on firms' financial constraints
Silva, Filipe; Carreira, CarlosThis paper is a brief survey of recent empirical work on financial constraints faced by firms. It is organized as a series of stylized results which mirror what is generally understood about severity of financial constraints and effects that they have upon firms. This survey shows that (a) the financial constraint is a widespread key concern for firms, hindering their ability to carry out their optimal investme...
Internal and external restructuring over the cycle: a firm-based analysis of gr...
Carreira, Carlos; Teixeira, PaulinoAbstract This paper discusses the role played by internal restructuring vis-à-vis external restructuring in industry productivity growth, arguing that the contribution of these two components is expected to be sensitive to the economic cycle. The study describes gross flows (job and output) over a period of one decade, and analyses the productivity differential among continuing, entering and exiting firms in t...
The Shadow of Death: Analysing the Pre-Exit Productivity of Portuguese Manufact...
Carreira, Carlos; Teixeira, PaulinoIn this study, we examine the pre-exiting productivity profile of mature firms relatively to survivors. We also evaluate how productivity affects the probability of exit along various dimensions. Our approach is an empirical one, and it is based on an unbalanced panel of Portuguese manufacturing firms covering a period of one decade. Our findings confirm that market selection forces low-productivity firms to ex...
Entry and exit as a source of aggregate productivity growth in two alternative ...
Carreira, Carlos; Teixeira, PaulinoThis paper proposes a neo-Schumpeterian model in order to discuss how the mechanisms of entry and exit contribute to industry productivity growth in alternative technological regimes. By assuming a) that firms learn about the technology through a variety of sources, and b) a continuous flow of entry and exit, our numerical simulation exercise does show that exits and contraction take mostly place among less pro...
A Abertura do Mercado de Telecomunicações Celulares ao Terceiro Operador: Uma D...
Carreira, Carlos M. G.Este trabalho investiga o grau de economias de escala, os custos marginais e os custos médios, nas empresas de telecomunicações móveis digitais, com base na função de custo translog. Os resultados permitem-nos concluir que os operadores estão localizados na zona de economias de escala crescentes e custos marginais decrescentes, tornando-se estes praticamente constantes a partir dos 3,5 milhões de assinantes. As...
