Mecanismos não-lineares de repasse cambial para o IPCA

This paper explores two changes in traditional models that measure the exchange rate pass-through in Brazil. The first change is a non-linear specification to the pass-through coefficient, making it depend on other variables that reflect economic conditions. The second change is to consider different components of the consumer price index, in search for transmission mechanisms of the exchange rate pass-through to prices. The empirical evidence obtained in the period between the quarter of 1994 and the last quarter 2001 suggests the existence of different non-linear mechanism among different price groups.

Salários, produtividade e lucros na indústria brasileira, 1945-1978

<abstract language="eng">Wages, productivity and profits in the Brazilian manufacturing industry, 1945-1978. This article investigates the distribution between profits and wages in Brazil's manufacturing industry from 1945 to 1978. First, the article provides yearly series of average real wages and labour productivity, from which labour unit costs and the distribution between profits and wages in the manufacturing industry are estimated. Second, the article addresses the behaviour of wages, labour productivity and industrial income distribution in the context of variable economic, political and institutional conditions which prevailed in post-war Brazil. The results of the quantitative analysis allow us to assess both the trends and the yearly behaviour of the manufacturing income distribution during a key period of the Brazilian economic history

A pesquisa em cognição e as atividades escolares de leitura Research on cognition and reading activities in school

Este artigo reúne pressupostos teóricos da Linguística Cognitiva e da Psicolinguística, em especial os estudos em metacognição, a fim de discutir problemas relacionados à leitura nas aulas de língua materna e estrangeira, principalmente no que tange à validação das questões de interpretação de textos. Para tanto, analisamos questões presentes em materiais didáticos de língua materna e estrangeira, a fim de sugerir formas de trabalhar a interpretação de textos, a partir da visão de que a cognição humana opera em basicamente dois planos de percepção/conceptualização. Conscientes da necessidade de abordar em várias frentes o problema da má qualidade de leitura do aluno brasileiro, apresentamos nossa proposta como parte de um projeto de pesquisa maior, que inclui o que o aluno pode aprender acerca do funcionamento de sua própria mente, e como pode utilizá-la satisfatoriamente para realizar as atividades de leitura que lhe são solicitadas, na escola e fora dela.<br>This paper assembles theoretical assumptions on Cognitive Linguistics and Psycholinguistics, especially those related to studies on Metacognition, in order to discuss problems on reading in native and foreign languages, mainly reading comprehension activities. We analyze activities of native and foreign language textbooks, in order to suggest interesting and relevant ways to work with reading comprehension, considering that human cognition basically operates in two levels of perception/conceptualization. Due to the need to address the problem of low quality of reading in Brazilian school in several ways, we present our proposal as a part of a greater research project, which includes how students can learn about their mind's work and how they can use it to accomplish reading activities in school and beyond
