Capital asset pricing model in Portugal: Evidence from fractal regressions

We examine risk profiles of the Portuguese stock market index component stocks using a novel approach to the classical capital asset pricing model (CAPM). Specifically, we estimate the CAPM via fractal regressions that allow studying the marginal effects at selected scales. In this way, we can reveal whether the risk is perceived differently by market participants with different investment horizons. Apart from the analysis itself, we provide new statistical insights into the issue of separating and comparing the scale-specific effects with statistical validity. We find several stocks deviating from an expected risk perception homogeneity across investment horizons. This is true for both analysed periods, i.e. before and after the global financial crisis. There are also several stocks that changed their relationship to the market portfolio in between, which has strong implications for possible portfolio construction. The proposed methodology is not limited to financial topics but can be used in any discipline where the scale-specific marginal effects might be of interest.     

Accounting and slavery: the accounts of the English South Sea Company, 1713-22

The Asiento was an agreement between the Crowns of England and Spain of tremendous economic and political consequences. In spite of its importance, very little is known about the accounting practices of the Asiento. This paper demonstrates that the developments of the Asiento were very much linked to the lack of accountability of the South Sea Company (SSC) before the Spanish Crown and describes the characteristics of the accounting system used by the SSC to provide information on its developed economic activity. It also discusses the role of accounting in the resolution of conflicts between the tenants of the Asiento, the SSC and its Spanish counterparts.     

To lead or to wait? An application to internationalization strategies under demand uncertainty

We examine the exports versus foreign direct investment (FDI) decision under demand uncertainty for an asymmetric cost duopoly. One of the firms can lead entry before demand realization or retain flexibility enjoying an informational advantage. When the time value of information is small and for sufficiently low investment costs, follow‐the‐leader behavior in FDI arises. Relatively high investment (fixed) costs result in follow‐the‐leader exporting behavior. When the time value of information becomes significant, the potential leader will opt for a wait‐and‐see strategy. For intermediate values of investment costs, the efficient firm invests, while the rival chooses to export.

Relevance of the EU Banking Sector to Economic Growth

Using panel estimates and a sample including all 28 European Union (EU) countries, this paper seeks to improve upon the existing literature with empirical evidence on the role that banking institutions can play in promoting economic growth. Banking sector performance is proxied by relevant operational, capital, liquidity and asset quality financial ratios. Economic growth is represented by the annual gross domestic product (GDP) growth rate. The estimations take into account the recent international financial crisis and consider three panels: one for the time period 1998–2012, a second one for the years before the crisis (1998–2006) and another for the subinterval 2007–2012. The results allow us to draw conclusions not only about the importance of the various financial ratios to economic growth but also regarding reactions to the recent crisis.     

Do Institutions Cause Growth?

We revisit the debate over whether political institutions cause economic growth, or whether, alternatively, growth and human capital accumulation lead to institutional improvement. We find that most indicators of institutional quality used to establish the proposition that institutions cause growth are constructed to be conceptually unsuitable for that purpose. We also find that some of the instrumental variable techniques used in the literature are flawed. Basic OLS results, as well as a variety of additional evidence, suggest that (a) human capital is a more basic source of growth than are the institutions, (b) poor countries get out of poverty through good policies, often pursued by dictators, and (c) subsequently improve their political institutions.     

Le partenariat public-OSBL dans les services sociaux. Le cas espagnol

The article considers the social services supply in the Spanish area of Valencia. The objective is double. First the authors analyse what describes the partnership between public sector and NPO in this area, by using a systemic conception of the social services sector where three main functions can be identified (financing, production and distribution, and regulation). Secondly they search for theoretical arguments explaining this partnership principle. This second section is mainly based on the NPO approach.     

The effect of US holidays on the European markets: when the cat’s away…

This paper presents evidence of the existence of a return effect on European stock markets coinciding with New York Stock Exchange (NYSE) holidays, which is particularly marked after positive closing returns on the NYSE the previous day. The effect is large enough to be exploited by trading index futures. This anomaly cannot be explained by seasonal effects, such as the day of the week effect, the January effect or the pre‐holiday effect, nor is it consistent with behavioural finance models that predict positive correlation between trading volume and returns. However, examination of factors such as information volume or investor mix provides a reasonable explanation.     

Calm After the Storms: Income Distribution and Welfare in Chile, 1987-94

After rising during most—but not all—of the 1960–85period, inequality in Chile seems to have stabilized since around1987. Following the stormy period of economic and politicalreforms of the 1970s and 1980s, no statistically significantLorenz dominance results could be detected since 1987. Scalarmeasures of inequality confirm this picture of stability, butsuggest a slight change in the shape of the density function,with some compression at the bottom being "compensated for"by a stretching at the top. As inequality remained broadly stable,sustained economic growth led to substantial welfare improvementsand poverty reduction, according to a range of measures andwith respect to three different poverty lines. Poverty mixedstochastic dominance tests confirm this result. All of thesefindings are robust to different choices of equivalence scales.
