- How many educated workers for your economy? European targets, optimal public spending, and labor market impactPublication . Lebon, Isabelle; Rebière, ThérèseThis paper studies optimal taxation schemes for education in a search- matching model where the labor market is divided between a high-skill and a low-skill sector. Two public policy targets - maximizing the total employment level and optimizing the social surplus - are studied according to three different public taxation strategies. We calibrate our model using evidence from thirteen European countries, and compare our results with the target from the Europe 2020 Agenda for achievement in higher education. We show that, with current labor market char- acteristics, the target set by governments seems compatible with the social surplus maximization objective for some countries, while being too high for other countries. For all countries, maximizing employment would imply higher educational spending than that required for the social surplus to reach its maximum.
- Momentum meets value investing in a small European marketPublication . Lobão, Júlio; Azeredo, MarcosIn this paper, we investigate two prominent market anomalies documented in the finance literature – the momentum effect and value-growth effect. We conduct an out- of-sample test to the link between these two anomalies recurring to a sample of Portuguese stocks during the period 1988–2015. We find that the momentum of value and growth stocks is significantly different: growth stocks exhibit a much larger momentum than value stocks. A combined value and momentum strategy can generate statistically significant excess annual returns of 10.8%. These findings persist across several holding periods up to a year. Moreover, we show that macroeconomic variables fail to explain value and momentum of individual and combined returns. Collectively, our results contradict market efficiency at the weak form and pose a challenge to existing asset pricing theories.
- The Dutch disease revisited : absorption constraint and learning by doingPublication . Iacono, RobertoThis paper revisits the Dutch disease by analyzing the general equilibrium effects of a resource shock on a dependent economy, both in a static and dynamic set- ting. The novel aspect of this study is to incorporate in one coherent framework two distinct features of the Dutch disease literature that have previously been analyzed in isolation: capital accumulation with absorption constraint, and productivity growth induced by learning-by-doing. The result of long run exchange rate appreciation is maintained in line with part of the Dutch Disease literature. In addition, a permanent change in the employment shares occurs after the resource windfall, in favor of the non-traded sector and away from the traded sector growth engine of the economy. In other words, in the long run both of the classic symptoms of the Dutch Disease remain in place.
