Portugal–EU Convergence Revisited: Evidence for the Period 1960–2003

This paper uses the stochastic approach to convergence to investigate whether real per capita GDP in Portugal has been converging to the EU15 average. The estimation accounts for conditional convergence, transitional dynamics and up to two structural breaks. It is found that per capita GDP in Portugal has indeed converged to the EU15 average, but the pace of convergence has not been uniform along time. In particular, a slow down in the convergence process is identified in 1974. This result depends, however, as to whether the choice of this break-date is viewed as uncorrelated with the data. No evidence of acceleration in the speed of convergence is found after EC accession, in 1986.An earlier version of this paper was presented at the Fifty-Ninth International Atlantic Economic Conference, London, England, March 9–13, 2005.

The time dependent vehicle routing problem with time windows: Benchmark problems, an efficient solution algorithm, and solution characteristics

An algorithm that can tackle time dependent vehicle routing problems with hard or soft time windows without any alteration in its structure is presented. Analytical and experimental results indicate that average computational time increases proportionally to the number of customers squared. New replicable test problems that capture the typical speed variations of congested urban settings are proposed. Solution quality, time window perturbations, and computational time results are discussed as well as a method to study the impact of perturbations by problem type. The algorithm efficiency and simplicity is well suited for urban areas where fast running times may be required.     

The Economic Adjustment Program for Portugal: assessing welfare impact in a heterogeneous-agent framework

The sovereign debt crisis, triggered by the 2007-08 global financial crisis, has affected several European Union (EU) countries, leading to unprecedented financial assistance programs. In May 2011, the Portuguese Government set an agreement with the Troika (a supranational institution composed by the European Commission (EC), the European Central Bank (ECB) and the International Monetary Fund (IMF)), through which, in exchange for external help, the Portuguese authorities committed to an Economic Adjustment Program (EAP). In order to assess the impacts of the EAP on welfare and, in particular, on inequality, this paper simulates the debt consolidation strategy proposed by the Troika using a general equilibrium model with heterogeneous agents. The model enables to explore the impacts of the fiscal adjustment on the endogenous cross-section distribution of income, wealth and welfare. Our results predict a positive net welfare gain, despite the existence of significant transition costs in terms of output losses and inequality, especially during the first years of implementation. Overall, the net positive welfare gains are biased towards the poorer, which means that the consolidation plan will be, in the end, equality-enhancing. These results reflect the instruments involved in the consolidation strategy: productive and unproductive expenditure cuts combined with a slight increase in social transfers. Furthermore, the simulation predicts a positive impact on the Portuguese net foreign asset (NFA) position. Assuming this prediction is correct, this strongly supports the motivation for the adoption of the Economic Adjustment Program which considers the large external indebtedness of Portugal as a central issue in the economic diagnosis.     

The moderating role of past experience in the formation of a tourist destination's image and in tourists’ behavioural intentions

The aim of this work is to understand the moderating effects of tourists’ prior experiences of a given destination on the process of image formation (in both its cognitive and affective dimensions) for that destination and on the influence that the image – together with the tourist's satisfaction – has on their loyalty-driven behaviours as expressed in the intention to recommend. To achieve this aim, a sample of 512 tourists was used and a multi-group analysis performed, distinguishing between first-time and repeat visitors. The findings reveal that experience has a moderating effect on the formation of the cognitive image and on the influence of the tourist's satisfaction on the overall image of the tourist destination. These findings have significant management implications in the context of helping to create and appropriately manage the image of a tourist destination.     

Measurement Error in Education and Growth Regressions*

The use of the perpetual inventory method for the construction of education data per country leads to systematic measurement error. This paper analyzes its effect on growth regressions. We suggest a methodology for correcting this error. The standard attenuation bias suggests that using these corrected data would lead to a higher coefficient. Our regressions reveal the opposite. We discuss why this is the case.     

Tradability and market penetration costs: Explaining foreign market servicing intensities

Industry level data shows striking differences among sectors in ratios of exports to FDI sales. We identify the elements behind the sectoral differences in the mode of foreign market servicing in the context of a general equilibrium model of monopolistic competition. Our calibration exercise shows that traditional margins such as transportation, fixed entry costs, utility weights, and dispersion of firm productivity are not enough to capture the observed sectoral differences, as is commonly assumed. We propose augmenting the model to allow for sectoral differences in intangible costs of operating in a foreign market in order to explain these observations.     

A financial stability index for Colombia

The imbalances of the financial systems have showed the vast economic and social costs generated by financial instability. As a consequence, the development of stress indexes has spread as an alternative to assess the soundness of financial systems. The aim of this paper is to construct a continuous and quantifiable index with the capacity of establishing the stress level of the Colombian financial system as a function of profitability, liquidity and probability of default. Results show that the index determines effectively the stress level of the system. In addition, we performed forecasts of the financial stability index using macroeconomics variables.     

Corporate entrepreneurship and acquisitions: creating firm wealth

Acquisition is one way entrepreneurial firms have to capture the assets needed to achieve their strategic objectives. We investigate shareholder value creation of Spanish listed firms in response to announcements of acquisitions over the period 1991–2006. Similar to foreign markets, bidders earn insignificant average abnormal returns regardless of the pricing model used in the estimation procedure. When we relate these results to company and transaction characteristics our evidence suggests that the listing status of the target firm is a critical key in the strategic decision to acquire a company. This listing status effect is mainly associated with the fact that unlisted firms tend to be smaller and lesser–known firms, and thus suffer from a lack of competition in the market for corporate control. Consequently, the payment of lower premiums and the possibility of diversifying shareholders’ portfolios lead to unlisted firm acquisitions being viewed as value–orientated transactions which have major implications for managers.     

Partner Selection Decisions in Interfirm Collaborations: The Paradox of Relational Embeddedness

By combining insights from relational network theory and agency theory we identify the boundary conditions to the embeddedness approach to partner selection decisions in interfirm collaborations. Employing a longitudinal dataset comprising the investment syndicates for the population of UK management buyouts between 1993 and 2003, we find that relational embeddedness is less important for selecting partners when agency risks are low, allowing firms to expand their networks. Furthermore, reputational capital may act as a partial substitute for relational embeddedness, again permitting firms to expand their networks. Our findings enhance understanding of the boundary conditions associated with the relational network approach to partner selections and network behaviour.
