Uncovering the US term premium: An alternative route

The estimates of the US term premium crucially depend upon the ex-ante decision on whether the short-term rate is either an I(0) or an I(1) process. In this paper we estimate a fractionally integrated (I(d)) model which simultaneously determines both the order of integration of the short-term rate and the associated term premium. We show that the term premium experienced a sharp increase from essentially zero in mid-2007 to almost 3% in 2009. We also show that unemployment and term premium dynamics exhibit a very significant positive co-movement.     

Organic food consumption in Europe: International segmentation based on value system differences

In this paper, we analyze the market for organic products in eight European countries, based on differences in their respective value systems. With a significant sample of 8014 consumers, we first identify international segments in the European organic products market using the Values Theory. Then we apply the Theory of Planned Behavior to examine how European consumers use attitudes, subjective norms and perceived behavioral control to form their purchase intention for organic products. Results show that subjective norms are the main underlying factor driving consumer behavior concerning these products. This effect is higher for the group of countries whose citizens score higher on Schwartz's value scale. In this segment of countries, people are more likely to be affected by what others think, which means that the best approach is to increase social awareness of the relevance of purchasing organic products. Organic products represent a potentially profitable opportunity for companies with an international horizon. Results are also useful for consumers and public administrations.     

Strong dependence in the real interest rates

The stochastic behaviour of the real interest rates in ten European countries, Canada and the US is examined in this article by means of fractionally integrated techniques. Using a procedure, specifically designed for testing I (d) statistical models, the results show that the real interest rates are more persistent in some countries like France, Belgium or the USA than in others like the UK or Germany.     

Sexual Orientation and Labor Force Participation: Findings from Chile and Uruguay

This is the first study that examines the association between sexual orientation and labor force participation in Chile and Uruguay. Using information on heads of households and their partners from recent census data, it applies a simple econometric methodology to measure the relationship of sexual orientation and labor participation, juxtaposing individuals who are part of straight and same-sex couples, while determining any difference in this association according to gender. The study finds that partnered gay men are up to 5.0 percentage points less likely to participate in the workforce compared to married straight men. In addition, lesbians are up to 32.7 percentage points more likely to participate in the labor force compared to married straight women. Trends between the two countries are similar, but the likelihood of participating in the labor force differs significantly. Conservatism in the cultural context and legal frameworks of each country arises as a possible explanation.     

SAVING AND INVESTMENT: PARADIGMS, PUZZLES, POLICIES

The 1990s have seen a renewed interest in issues of capitalaccumulation and growth. New paradigms for saving, investment,and growth have been advanced to address theoretical and empiricalpuzzles and to guide the design of better policies. This paperprovides a policy-oriented review of recent theoretical andempirical work on the determinants of saving and investmentand on their links to growth. It takes stock of new findingsas well as still unresolved questions and gives particular attentionto empirical regularities and to the policy issues relevantto developing countries.      

Long memory and mean reversion in real exchange rates in Latin America

This article examines the long-run Purchasing Power Parity (PPP) hypothesis for 12 Latin American Real Effective Exchange Rates (REERs) using fractional integration techniques. The empirical results, applying parametric approaches, provide evidence of mean reversion in the REERs in the cases of Nicaragua, Belize, Costa Rica, Guyana and Paraguay and lack of it for the remaining seven countries. Employing semiparametric methods, the evidence of mean reversion covers the following countries: Belize, the Dominican Republic, Ecuador and Mexico. Thus, only for Belize and Guyana do we obtain consistent evidence of mean reversion in the real exchange rates. At the other extreme, lack of mean reversion, and thus, lack of PPP, is obtained with both methods in Bolivia, Brazil, Colombia and Venezuela. For the remaining six countries, the results are ambiguous. The results for the PPP theory in Belize and Guyana may show the importance of promoting policies based on exchange rate flexibility and economic liberalization to reach a long-run stability scenario that leads to greater international competitiveness and lower external vulnerability.     

Fractional cointegration and real exchange rates

This paper uses fractional integration and cointegration to model the DM-US dollar and the yen-US dollar real exchange rates in terms of both monetary and real factors, more specifically real interest rate and labour productivity differentials. We find that whilst the individual series may be integrated of order 1, their long-run relationship might have a fractionally cointegrated structure. This means that mean reversion occurs, consistently with the findings of other studies. However, it also indicates, in contrast to such studies, that the cointegrating relationship possesses long memory. In other words, the error correction term responds slowly to shocks, implying that deviations from equilibrium are long-lived. It appears that only a combination of real and monetary variables can accurately track down the movements of real exchange rates.     

Efficiency measurement using a latent class stochastic frontier model

Efficiency estimation in stochastic frontier models typically assumes that the underlying production technology is the same for all firms. There might, however, be unobserved differences in technologies that might be inappropriately labeled as inefficiency if such variations in technology are not taken into account. We address this issue by estimating a latent class stochastic frontier model in a panel data framework. An application of the model is presented using Spanish banking data. Our results show that bank-heterogeneity can be fully controlled when a model with four classes is estimated.
