Teorias em estrat��gia

A estrat��gia empresarial �� uma disciplina jovem. Comparado com os campos de estudo de economia e sociologia o campo de estrat��gia empresarial pode ser visto como um fen��meno de forma����o mais recente, embora extremamente din��mico em sua capacidade de criar abordagens te��ricas diferenciadas. Este trabalho discute a recente prolifera����o de teorias em estrat��gia empresarial, propondo um modelo de classifica����o destas teorias baseado na an��lise emp��rica do modelo de escolas de pensamento em estrat��gia empresarial desenvolvido por Mintzberg, Ahlstrand e Lampel em seu livro Saf��ri de Estrat��gia (1998). As poss��veis conseq����ncias relativas �� intera����o entre teoria e pr��tica s��o tamb��m discutidas apresentando o que definimos como a s��ndrome do ornitorrinco.

Terrores e mist��rios da adolesc��ncia e juventude: uma an��lise da prefer��ncia dos jovens pela hist��ria de terror

Life expectancy, educational attainment, and fertility choice

This paper explores the role of mortality as a determinant of educational attainment and fertility, both during the demographic transition and after its completion. Two main points distinguish our analysis from the previous ones. Together with the investments of parents in the human capital of children, traditional in the fertility literature, we introduce investments of adult individuals (parents) in their own education, which ultimately determines productivity in both the goods and household sectors. Second, we let adult longevity affect the way parents value each individual child. Increases in adult longevity or reductions in child mortality eventually raise the investments in adult education. Together with the higher utility derived from each child, this tilts the quality-quantity trade off towards less and better educated children, and increases the growth rate of the economy. This setup can explain both the demographic transition and the recent behavior of fertility in ���post-transition��� countries. Evidence from historical experiences of demographic transition, and from the recent behavior of fertility, education, and growth generally supports the predictions of the model.
