Education and Early Career Outcomes of Second-Generation Immigrants in France

We estimate a flexible dynamic model of education choices and early career employment outcomes of the French population. Individuals are allowed to choose between 4 options: continue to the next grade, accept a permanent contract, accept a temporary contract, or withdraw from the labor force (a residual state). Our analysis focuses on the comparison between French Second-Generation Immigrants whose parents are born in Africa and French-natives. We find that schooling attainments explain around two thirds of the differences in access to early career employment stability. However, one third cannot be linked to observed investment in human capital.schooling attainments, second-generation immigrants, fixed term employment

A spectral-like decomposition for transitive Anosov flows in dimension three

Given a (transitive or non-transitive) Anosov vector field $X$ on a closed three-dimensional manifold $M$, one may try to decompose $(M,X)$ by cutting $M$ along two-tori transverse to $X$. We prove that one can find a finite collection $\{T_1,\dots,T_n\}$ of pairwise disjoint, pairwise non-parallel incompressible tori transverse to $X$, such that the maximal invariant sets $\Lambda_1,\dots,\Lambda_m$ of the connected components $V_1,\dots,V_m$ of $M-(T_1\cup\dots\cup T_n)$ satisfy the following properties: 1, each $\Lambda_i$ is a compact invariant locally maximal transitive set for $X$, 2, the collection $\{\Lambda_1,\dots,\Lambda_m\}$ is canonically attached to the pair $(M,X)$ (i.e., it can be defined independently of the collection of tori $\{T_1,\dots,T_n\}$), 3, the $\Lambda_i$'s are the smallest possible: for every (possibly infinite) collection $\{S_i\}_{i\in I}$ of tori transverse to $X$, the $\Lambda_i$'s are contained in the maximal invariant set of $M-\cup_i S_i$. To a certain extent, the sets $\Lambda_1,\dots,\Lambda_m$ are analogs (for Anosov vector field in dimension 3) of the basic pieces which appear in the spectral decomposition of a non-transitive axiom A vector field. Then we discuss the uniqueness of such a decomposition: we prove that the pieces of the decomposition $V_1,\dots,V_m$, equipped with the restriction of the Anosov vector field $X$, are "almost unique up to topological equivalence".Comment: 22 pages, 4 figure

Expectations in an OG Economy

Dynamic economic models usually describe the path of economic variables as prices, consumption or capital at equilibrium. The most popular models assume that agents have perfect foresight. Implicitly this assumption requires that agents can compute the complete infinite path, an exercise that requires to solve a system of equations involving an infinite num- ber of equations and unknowns. Equivalently, one could assume that there is a well behaved and fast mechanism driving the economy to the temporary equilibrium. A major difficulty is that the behavior of the consumers in any given period depends on the present and all the fu- ture prices. In the paper, we consider an overlapping generation model in which the consumers form expectations using truncated versions of the model. The mechanism of price adjustment may then be analyzed. Both the expectational dynamics, as treated in Balasko (1994), and the Wal- ras’s tatonnement, as in Hens (1997), are considered. Sufficient conditions for stability of the perfect foresight equilibrium within these price forma- tion mechanisms are derived. We also discuss the issue of the robustness of the results to parameters used in the truncation.expectations, learning, overlapping generations, computation of equilibria.
