International portfolio reallocation: Diversification benefits and European monetary union

We investigate the determinants of bilateral international equity and bond portfolio reallocation across a large cross-section of countries spanning over two sample periods: 1997-2001 and 1997-2005. We find that the strongest drivers are the marginal diversification benefits arising from the pure asset component and the initial degree of underweight. This evidence suggests that global portfolio reallocations over the asset boom and bust period were determined by optimal diversification considerations. We also find that due to economic and monetary union (EMU) the weight assigned by euro area investors to investment in euro area countries increased significantly in equity and fixed income portfolios, with a trade diverting effect against the British bond market.     

Capturing how individuals perceive genetic risk information: a phenomenological perspective

The prevailing scientific approach to genetic risk information centres around communication of risk in terms of numerical probabilities. However, it is well known that individuals have difficulties in understanding and making sense of this information in their own lives. There is, accordingly, a need to investigate whether any methodologies in psychological research may shed light on how individuals perceive genetic risk information within their specific contexts of family history, personal relationships, lifestyles and future plans. To explore whether hermeneutic phenomenology and methodology may offer a deeper understanding of an individual’s perception of having a hereditary predisposition, we conducted a literature search. We found that Interpretative Phenomenological Analysis may be a fruitful approach to an individual’s lived experiential world. The studies analysed showed how individuals interpret information about genetic risk in the light of their own beliefs about the multiple causes of illness, patterns of heredity and observable risk factors in their families. People’s understanding of their experience is derived from an intricate interconnectedness with others that arises in the context of a world shaped in equal measure by language and culture, on the one hand, and bodies and objects on the other.     

Optimal Export Taxes, Welfare, Industry Concentration, and Firm Size: A General Equilibrium Analysis

By using an imperfect-competition model, it is shown that an export tax, optimal in partial equilibrium, is upwardly biased and may not be optimal in a general equilibrium setting with free entry/exit. It is shown also that the export tax has an ambiguous impact on firm size. The results of an applied general equilibrium model for the Turkish economy suggest that the export tax estimated with the PE formula is larger by a small factor than the computed export tax. However, the export tax leads to an increase in firm size and, most importantly, to a social welfare loss.     

Impact of Environmental Regulations on Trade in the Main EU Countries: Conflict or Synergy?

In an increasingly integrated world with declining trade barriers, environmental regulations can have a decisive role in shaping countries’ comparative advantages. The conventional wisdom about environmental protection is that it comes at an additional cost on firms imposed by the government, which may erode their global competitiveness. However, this paradigm has been challenged by some analysts. In particular, Porter and van der Linde argue that pollution is often associated with a waste of resources and that more stringent environmental policies can stimulate innovations that may overcompensate for the costs of complying with these policies. This is known as the Porter hypothesis. While there is a broad empirical literature on the impact of trade on environment, the empirical literature on the impact of environmental regulations on trade flows is relatively scarce, very heterogeneous and presents mixed results. The innovative feature of this paper is its attempts to estimate, in a gravity setting, augmented with a proxi of environmental stringency, the impact of three major multilateral environmental agreements (MEAs) on 15 EU countries’ bilateral exports. According to our estimates, in the period 1988–2008, to be member of MEAs had a positive average impact on EU‐15 bilateral exports. This evidence can be partly explained by a possible trade diversion effect with respect to countries that did not sign MEAs and a corresponding trade creation effect among members of the environmental agreements. Furthermore, evidence coming from interaction effects estimates seems to show that for exporting countries, having signed the United Nations Framework Convention on Climate Change and the Montreal agreements partly mitigates (by the amount of the estimated coefficient) the negative impact of having a relatively more stringent environmental regulation on bilateral trade. This result could have important policy implications for the future international trade–environmental negotiations.     

Reserves,Sovereign Wealth Funds and the Resilience of Global Imbalances

Reserves and sovereign wealth funds (SWFs) assets should be jointly considered for the assessment of global imbalances, hence their denomination as sovereign external assets (SEAs): both are public capital outflows from developing to developed countries, both hinder adjustment in current account surplus and deficit countries and, therefore, both contribute to sustain global imbalances. They represented 135 per cent and 50 per cent of net and gross US financing needs, respectively, in 2007. Reserves contribute 80 per cent and SWFs 20 per cent. They will go on providing resilience to the global imbalances, and the relative importance of SWFs is set to increase if commodity prices stay high.     

The empirical risk–return relation: A factor analysis approach

Existing empirical literature on the risk–return relation uses relatively small amount of conditioning information to model the conditional mean and conditional volatility of excess stock market returns. We use dynamic factor analysis for large data sets, to summarize a large amount of economic information by few estimated factors, and find that three new factors—termed “volatility,” “risk premium,” and “real” factors—contain important information about one-quarter-ahead excess returns and volatility not contained in commonly used predictor variables. Our specifications predict 16–20% of the one-quarter-ahead variation in excess stock market returns, and exhibit stable and statistically significant out-of-sample forecasting power. We also find a positive conditional risk–return correlation.
