Two Essays on the economics of Education

We develop a job-market signaling model where signals may convey two pieces of information. This model is employed to study the GED exam and countersignaling (signals non-monotonic in ability). A result of the model is that countersignaling is more expected to occur in jobs that require a combination of skills that differs from the combination used in the schooling process. The model also produces testable implications consistent with evidence on the GED: (i) it signals both high cognitive and low non-cognitive skills and (ii) it does not affect wages. Additionally, it suggests modifications that would make the GED a more effective signal.

The costs of education, longevity and the poverty of nations

This paper explores the distortions on the cost of education, associated with government policies and institutional factors, as an additional determinant of cross-country income differences. Agents are finitely lived and the model takes into account life-cycle features of human capital accumulation. There are two sectors, one producing goods and the other providing educational services. The model is calibrated and simulated for 89 economies. We find that human capital taxation has a relevant impact on incomes, which is amplified by its indirect effect on returns to physical capital. Life expectancy plays an important role in determining long-run output: the expansion of the population working life increases the present value of the flow of wages, which induces further human capital investment and raises incomes. Although in our simulations the largest gains are observed when productivity is equated across countries, changes in longevity and in the incentives to educational investment are too relevant to ignore.

The impact of structured teaching methods on the quality of education

This paper estimates the impact of the use of structured methods on the quality of education of the students in primary public school in Brazil. Structure methods encompass a range of pedagogical and managerial instruments applied to the education system. In recent years, several municipalities in the State of São Paulo have contracted out private educational providers to implement these structured methods in their schooling system. Their pedagogical proposal involves structuring curriculum contents, elaboration and use of teachers and students textbooks, and training and supervision of the teachers and instructors. Using a difference in differences estimation strategy, we find that the fourth and eighth grader students in the municipalities with structured methods performed better in Portuguese and Math than students in municipalities not exposed to the methods. We find no differences in approval rates. However, a robustness check is not able to discard the possibility that unobserved municipal characteristics may affect the results.

Accountability and yardstick competition in the public provision of education

This paper explores the institutional change introduced by the public disclosure of an education development index (IDEB, Basic Education Development Index) in 2007 to identify the e ect of education accountability on yardstick competition in education spending for Brazilian municipalities. Our results are threefold. First, political incentives are pervasive in setting the education expenditures. The spatial strategic behavior on education spending is estimated lower for lame-ducks and for those incumbents with majority support at the city council. This suggests a strong relation between commitment and accountability which reinforces yardstick competition theory. Second, we nd a minor reduction (20%) in spatial interaction for public education spending after IDEB's disclosure | compared to the spatial correlation before the disclosure of the index. This suggests that public release of information may decrease the importance of the neighbors` counterpart information on voter`s decision. Third, exploring the discontinuity of IDEB`s disclosure rule around the cut-o of 30 students enrolled in the grade under assessment, our estimates suggest that the spatial autocorrelation | and hence yardstick competition | is reduced in 54%. Finally, an unforeseen result suggests that the disclosure of IDEB increases expenditures, more than 100% according to our estimates.

A USAID e a educação brasileira: um estudo a partir de uma abordagem crítica da teoria do capital humano

1\ guisa de uma fundarrentação teórica, procura esta dissertação, desmistificar tcx:1a uma noção de neutralidade conceitual do capital desenvolvida em função de una visão ideol~izada da economia da educação. A critica a este preconceito procurou se respaldar nos argumentos de autoridade dos classicos da economia; igualrrente, tenta desideologi zar a noção de capital humano, cujo desenvolvirrento é irrpropriarcente ~ tribuido à função da educação; e finaJ..nente, dirrensiona-a, no cont:exto prÕprio do ideário capitalista. Procura dem::mstrar que a ajuda proporcionada pela USAID ao processo educacional brasileiro era mais uma tentativa de garantir o lucro dos capitais investidos no Brasil, na rredida em que o aparelho ~ ducativo produzisse um contigente de mão de obra eficientemente capaz' de implerrentar o novo mcx:1elo econômico, implantado a partir de 1964. Olestiona a rrodernização do subsistema de ensino rrédio, considerado em função do "efeito derronstração" das Escolas polivalentes , que buscava adaptar o aparelho escolar ã racionalidade da empresa, na rredida em que, assim, internalizava, no alunaCio, pela profissionalização precoce, os valores capitalistas da competição e do lucro, COItO va leres universais. Discute a EPEM e o PREMEN como organismos criados para impl~ rrentar a transformação do subsistema de ensino nédio. Análisa as Confe rências de Educação e questiona o ideário da Escola Polivalente, identificando- o como contraditório e inconsistente para o modelo de sociedade sob o modo de produção capitalista, conforme é proposto pelo atual sistema de governo no Brasil. O seu conteúdo pretende atingir a profissionais de educação' em geral, e mais especificamente aos interessados em economia da educação,sociologia da educação e estudos sociais.
