On the construction of a finite Siegel space

In this note we construct a finite analogue of classical Siegel's Space. Our approach is to look at it as a non commutative Poincare's half plane. The finite Siegel Space is described as the space of Lagrangians of a $2n$ dimensional space over a quadratic extension $E$ of a finite base field $F$. The orbits of the action of the symplectic group $Sp(n,F)$ on Lagrangians are described as homogeneous spaces. Also, Siegel's Space is described as the set of anti-involutions of the symplectic group.2

Ricardian Equivalence Proposition in a NK DSGE Model for two Large Economies: The EU and the US

This paper examines the macroeconomic effects of active fiscal policy management coupled with a monetary policy that follows the Taylor principle. The objective is to investigate the relevance of the Ricardian Equivalence Proposition (REP) in a framework where two large open economies interact and a fraction of the consumers is financially constrained. According to an estimated vector autoregressive model, a positive shock in government expenditure leads to an increase in private consumption (at odds with the permanent income hypothesis). The channels are studied in a fully microfounded dynamic stochastic general equilibrium model economy calibrated for the Euro Area (EU-12) and for the United States. The crucial parameter that drives the break of the REP is the share of financially constrained consumers. Firms produce tradable varieties in a monopolistic competition framework and pricing is à la Calvo, which leads to nominal price stickiness. Labor varieties are immobile across countries and are demanded in an aggregated fashion by firms. Fiscal policy is specified as a time-consistent rule. We simulate through impulseresponse functions parameterizations that yield results consistent with the REP, and estimate a subset of deep parameters employing Bayesian techniques.

Education, Gender and Youth in the labor market in Argentina

The main goal of this paper is to show the importance of secondary education in the results of Argentine youth in the labor market, both empirically and with existing data, and differentiating impacts by gender. The evidence suggests that secondary education promotes greater participation in the labor force and it does so in a higher degree among young women than young men. Also, compared with primary education, secondary school increases the employment opportunity of youth and has a positive effect on remuneration for both gender, but effect is more positive among boys than among girls.
