Institutions and economic growth in Portugal: a quantitative exploration

This paper presents a broad diagnostic of the level of institutional development in Portugal in the legal, corporate governance and financial systems. A comparative assessment suggests that Portuguese institutions are less developed than their European Union and East Asian counterparts, more developed than Greek institutions and on a level similar to that of Spanish institutions. We use data for a wide cross-section of countries since 1960 and correlate indicators of institutional development with the long-term average growth rate, identifying issues where reform is likely to significantly affect economic growth. We construct three new indices that measure the potential of institutional reform - the impact of reform on growth, the required reform effort and the efficiency of reform index - by taking into consideration the institutional distance between Portugal and the European Union. These indices measure, respectively, which reforms have the most payoff in terms of growth, which are less costly to undertake and which deliver the most growth per required effort. Our results strongly suggest that in a large number of issues, institutional reform may translate into substantially higher rates of economic growth. Of the ten most promising reforms, six are in the legal area, irrespective of which of the indices is considered. Whereas legal reform is promising at the aggregate and the microeconomic levels, in the financial sector aggregate indicators offer the wider scope for productive reform, while in the corporate governance area it is indices at the micro level that hold the most promise. These results support the view that a comprehensive reform effort is likely to deliver higher rates of growth in Portugal, allowing faster real convergence with the rest of the European Union.Received: January 2003, Accepted: February 2004, JEL Classification: O0, O5, K00, K4, G2, G3This paper is based on Firms, Financial Markets and the Law: Institutions and Economic Growth in Portugal, prepared for the conference Desenvolvimento Económico Português no Espaço Europeu: Determinantes e Políticas, organized by the Banco de Portugal.

Job and worker flows in high adjustment cost settings

This paper analyses the relationship between the size of adjustment costs and the intensity of labor market flows. I argue that high adjustment costs inhibit adjustment to temporary shocks, leaving adjustment to long-lived shocks unchanged. Worker turnover is also reduced because of the negative impact that adjustment costs have on churning.Received: January 2002, Accepted: November 2002, JEL Classification: J23, J63I am grateful to the FCT for funding this research (research grant Praxis/PCSH/C/CEG/13/96), and to Pedro Portugal, Daniel Hamermesh and two anonymous referees for helpful comments on earlier versions of this paper.

Does IMF Support Accelerate Inflation Stabilization?

This paper analyzes the effects of International Monetary Fund (IMF) arrangements on the timing of inflation stabilization programs. By providing financial support that may allow the reduction of inflation without incurring politically unacceptable economic costs, the IMF can hasten stabilization. But, since support can also reduce the costs of inflation, it may instead delay it. Empirical results obtained for 10 countries that suffered from chronic inflation fail to support the hypothesis that IMF financial assistance accelerates stabilization. Rather, they indicate that other factors have a greater impact on the timing of stabilizations: greater fragmentation of the political system delays stabilization, while a higher level of inflation hastens it.

Economic performance and international trade engagement: the case of Portuguese manufacturing firms

By combining economic and financial data for Portuguese manufacturing firms with data on their exports and imports, we uncover some aspects of the relationship between international trade engagement and firms’ performances. In line with recent theoretical and empirical developments in the international trade literature: (i) we testify that Portuguese international trade is highly concentrated, especially on the import side, and both in inter- and intra-sector terms; (ii) we corroborate previous studies and theses according to which two-way traders outperform only importers, only exporters and above all domestic firms; (iii) we find that the greater the diversification of markets and goods (especially with regard to imports), the better the performance achieved by internationalised firms; (iv) we notice that the higher the intensity of firms’ international trade (especially imports), the better their performance; (v) we also present evidence that destination markets for exports and origin markets for imports are also important in explaining firm’s performance.     

The Portuguese business cycle: chronology and duration dependence

This paper tries to identify a chronology for the Portuguese business cycle and test for the presence of duration dependence in the respective phases of expansion and contraction. A duration-dependent Markov-switching vector autoregressive model is employed in that task. This model is estimated over year-on-year growth rates of a set of relevant economic indicators, namely industrial production, a composite leading indicator and, additionally, civilian employment. The estimated specifications allow us to identify four main periods of contraction during the last three decades and some evidence of positive duration dependence in contractions, but not in expansions, especially when employment is added to the model.     

Predation and reputation acquisition in debt markets

This paper presents a model of predation based on reputational differences between the entrant and an incumbent. While the incumbent has an established reputation in the debt market, the entrantss quality is not yet known in the debt market. We show that the incumbent may have incentives to prey in order to interfere with the reputation acquisition of the entrant.Received: June 2002 , Accepted: December 2002, JEL Classification: C72, D82, G3, L1I am grateful to one anonymous referee for very valuable comments.

Human capital,innovation capability and economic growth in Portugal, 1960-2001

In maintaining that the main flaw in empirical studies on economic growth derives from the fact that they employ Solow-style neoclassical growth models, rather than testing actual endogenous growth theory, we examine the human capital-innovation-growth nexus, thus testing new growth theory more directly. We test its insights against the economic evolution of an individual country, Portugal, using time series data from 1960 to 2001. Estimates based on vector autoregressive and cointegration analysis seem to confirm that human capital and indigenous innovation efforts were enormously important to the economic growth process in Portugal during the period of study. In particular, the indirect effect of human capital through innovation, emerges here as being critical, showing that a reasonably high stock of human capital is necessary to enable a country to reap the benefits of its indigenous innovation efforts.Received: November 2003, Accepted: November 2004, JEL Classification: C22, J24, O30, O40 Correspondence to: Aurora A.C.

Structure and performance in the Portuguese banking industry in the nineties

In this paper we study the structure-performance relationship in the Portuguese banking industry during the nineties. The hypothesis of pure collusion, efficient structure, modified efficient structure and hybrid collusion/efficiency are tested using a direct measure of efficiency. Our results endorse the hybrid collusion/efficiency hypothesis in the first half of the nineties. However, after 1994 results lend some support to the modified efficient structure hypothesis. Competition at the local level remains important throughout the decade, suggesting that banks in less competitive local markets exert some level of market power and exhibit superior performances.Received: November 1999, Accepted: February 2003, JEL Classification: C21, L11Correspondence to: Victor MendesThe authors wish to thank Pedro Pita Barros and two anonymous referees for helpful comments.

Maturity and volatility effects on UK smiles

The smile effect is a result of an empirical observation of the options implied volatility with the same expiration date, across different exercise prices. However, its shape has been under discussion seeming to be dependent on the option underlying security. In this paper, and filling up a scarce empirical research on the topic, we used liquid equity options on 9 stocks traded on the London International Financial Futures and Options Exchange (LIFFE) between August 1990 and December 1991. We tested two different hypothesis for testing two different phenomena: (1) the increase of the smile as maturity approaches; (2) and the association between the smile and the volatility of the underlying stock. In order to estimate implied volatilities for unavailable exercise prices, we modelled the smile using cubic B-spline curves. We found empirical support for the smile intensification (the U-shape is more pronounced) as maturity approaches as well as when volatility rises. However, we found two major sources of disagreement with the literature on stochastic volatility models. First, as maturity approaches, out-of-the-money options implied volatility tends to be higher than the implied volatility of in-the-money options. Second, as the volatility of the underlying asset increases, the implied volatility of in-the-money options tends to be higher than implied volatility of out-of-the-money options.Received: September 2001, Accepted: September 2003, JEL Classification: G13Correspondence to: João L.

Business Cycles,Core, and Periphery in Monetary Unions: Comparing Europe and North America

Using different levels of regional aggregation, we compare Europe with the USA and Canada as regards business cycle synchronization and core-periphery patterns. A long annual sample (1950–2005) makes it possible to study how these aspects have evolved over time. Results support the economic viability of EMU. Average cyclical correlations among European countries have risen significantly, reaching levels close to those of North American regions. Applying fuzzy clustering to the analysis of core-periphery issues, we find European countries to actually outperform USA Census Regions: the core-periphery divide is milder, and peripheral status seems generally less protracted.
