The consumer loss of the minimum duration for mobile telephone calls

This article estimates price elasticities of demand for the duration of mobile telephone calls for Portugal, as well as the monetary loss per consumer of the existence of a minimum duration of calls. The demand for the duration of calls is estimated using a Tobit model for panel data with individual random effects. The elasticity of demand is found to be small and to vary across firms. At current prices, the average duration of calls ranges between 101 and 109 s, while the estimated average length of calls without minimum duration ranges between 63 and 66 s. Hence, the existence of a minimum duration for calls results in a monetary loss of 35–40% of the average invoice.     

Public Capital Formation and Regional Development in Spain

This paper uses a vector autoregression (VAR) approach to evaluate the effects of public investment on private sector performance in Spain. Empirical results suggest that public investment positively affected private investment, employment, and output at both aggregate and regional levels. The regions that benefited the most from public investment in the last two decades were Cataluña, Madrid, and Pais Vasco. These regions are among the largest economic areas in the country and among the ones with the highest GDP per capita. Accordingly, public investment, while an important factor for aggregate economic growth, has also been a source of increasing regional asymmetries.     

Incentives to invest and to give access to non-regulated new technologies

We analyze the incentives of a vertically integrated firm, which is a regulated monopolist in the wholesale market and competes with an entrant in the retail market, to invest and to give access to a new wholesale technology. The new technology represents a non-drastic innovation that produces retail services of a higher quality than the old technology, and is left unregulated. We show that for intermediate values of the access price for the old technology, the vertically integrated firm may decide not to invest. When investment occurs, the vertically integrated firm may be induced to give access to the entrant for a low access price for the old technology. Furthermore, when both firms can invest, investment occurs under a larger set of circumstances, and it is the entrant the firm that invests in more cases. We also discuss the implications for the regulation of the old technology.     

A longitudinal examination of HRM in a human resources offshoring (HRO) organization operating from India

Human resources offshoring (HRO) forms a significant part of the Indian business process offshoring (BPO) market. This paper assesses HRM in the emergent HRO sector. Longitudinal case-study research enables an in-depth examination of the development of HRM practices in an HRO organization where offshored HR services are delivered from two different cities in India. The paper highlights the development of HR activities focused on extrinsic incentives, rewards and penalties to influence employee behaviour. These practices are mediated by indigenous traditions, the nature of the service offering; management style and an aspiration to ‘role model’ systematic HR practices.     

Inter-industry Wage Dispersion in Portugal

The emerging notion that corporatism/centralisation reduces inter-industry wage dispersion is the main leading force behind this paper. We use data from a long series of comparable datasets to analyse the evolution of the size of inter-industry wage dispersion in Portugal. We compare the results with the ones obtained in other countries to find that the country has a high inter-industry wage inequality when compared with the European standard. Nevertheless, the dispersion decreased during the second half of the 1980s along with the establishment of a neo-corporatist setting, supporting the expected reduction.     

Spillover Effects of Tourism Consumption Between Galicia and the Rest of Spain

Analysing the spillover effects is crucial for small and open regions where productive leakages are relevant, as could be the case of Galicia within the Spanish context. Therefore, the main aim of this paper is to examine the spatial interactions between Galicia and the rest of Spain economies that tourism consumption involves, for the period 2001–2007. An interregional input–output model is applied for the year 2005. Additionally, three different kinds of tourism consumption are considered: two inbound and a domestic one. Among other results, we found that around 1% of the gross value added of the small economy depends on the tourism consumption in the rest of the country.

Procurement cost reduction for customized non-critical items in an automotive supply chain: An action research project

This paper presents the processes involved in organizing a buyers' fair, a fair where first- and second-tier suppliers of the automotive industry make known their buying requirements for non-critical items to SMEs (small and medium-sized enterprises). The fair allowed the procurement process of LCs (large companies) and the prospecting process of SMEs to be faster and less-expensive. The fair was the result of an action research project performed by the researchers in partnership with the Brazilian Federation of Industries.     

The impact on broadband access to the Internet of the dual ownership of telephone and cable networks

In Portugal, until recently, the telecommunications incumbent offered broadband access to the Internet, both through digital subscriber line and cable modem. We estimate the impact on broadband access to the Internet of the structural separation of these two businesses. Using a panel of consumer level data and a random effects mixed logit model, we estimate the price elasticities of demand and the marginal costs of broadband access to the Internet. Based on these estimates, we simulate the effect of structural separation on prices and social welfare. Our estimates indicate that structural separation would cause a substantial welfare increase. These results raise questions about the policy of some countries of allowing the dual ownership of telephone and cable networks.     

Strategies for Fiscal Reform in the Context of the EMU: the Case of Portugal

The authors use an endogenous growth dynamic general‐equilibrium model, which accommodates the institutional constraints of the Stability and Growth Pact, to study tax reform in Portugal. Simulation results suggest that tax cuts financed in a nondistortionary way increase long‐term GDP; i.e., they are efficiency improving, but do not always increase welfare. The tradeoff between efficiency and welfare is alleviated when reductions in public spending or increased public indebtedness finance the tax cuts. Since these mechanisms are not realistic under the institutional setting of the Stability and Growth Pact, tax reform in Portugal must involve trading off distortionary tax margins. In this case, the best strategy to increase both efficiency and welfare is to increase investment tax credits and finance them either through personal income taxes or through employers’ social security contributions.
