Distortions in the investment goods sector and productivity decline

We study the impact of distortions in the investment goods sector on aggregate total factor productivity (TFP). We develop a two-sector neo-classical growth model in which TFP in the capital goods sector relative to TFP in the consumption sector is inversely related to the price of investment relative to consumption, so that we use relative prices to measure TFP in the investment goods sector. The model is calibrated to Brazil and we nd that distortions in the investment goods sector may explain most of the decline in Brazilian TFP relative to the United States since the mid-1970s.

The evolution of international output differences (1960-2000) : from factor to productivity

This article presents a group of exercises of leveI and growth decomposition of output per worker using cross-collntry data from 1960 to :2000. It is shown that at least llntil 197.5 factors of production (capital anel education) ",ere the main source of output dispersion across ecoIlomies and that productivity variance was considerably srnaller than in late years. Qnly after this date the prominence of productivity started to sho\\' up in the data. as the majority of the litcrature has found. The gro\\'th decomposition exercises showecl that t he reversal of relative irnportance of proeluctivity vis-a-\'is factors is explainecl by the very good (bad) performance of procluctivity of fast (slow) growing cconomies. Although growth in the pcriod, on avcragc. is mostly clue to factors accumulation. its variance is explained by productivity.

Can unobserved heterogeneity in farmer ability explain the inverse relationship between farm size and productivity?

The well-known inverse relationship between farm-size and productivity is usually explained in terms of diminishing returns with respect to land and other inputs coupled with various types of market frictions that prevent the efficient allocation of land across farms. We show that even if in the absence of diminishing returns one can provide an alternative explanation for this phenomenon using endogenous occupational choice and heterogeneity with respect to farming skills.

Why has productivity growth stagnated in most Latin American countries since the neo-liberal reforms?

Latin America’s economic performance since the beginning of neo-liberal reforms has been poor; this not only contrasts with its own performance pre-1980, but also with what has happened in Asia since 1980. I shall argue that the weakness of the region’s new paradigm is rooted as much in its intrinsic flaws as in the particular way it has been implemented. Latin America’s economic reforms were undertaken primarily as a result of the perceived economic weaknesses of the region — i.e., there was an attitude of ‘throwing in the towel’ vis-à-vis the previous state-led import substituting industrialisation strategy, because most politicians and economists interpreted the 1982 debt crisis as conclusive evidence that it had led the region into a cul-de-sac. As Hirschman has argued, policymaking has a strong component of ‘path-dependency’; as a result, people often stick with policies after they have achieved their aims, and those policies have become counterproductive. This leads to such frustration and disappointment with existing policies and institutions that is not uncommon to experience a ‘rebound effect’. An extreme example of this phenomenon is post-1982 Latin America, where the core of the discourse of the economic reforms that followed ended up simply emphasising the need to reverse as many aspects of the previous development (and political) strategies as possible. This helps to explain the peculiar set of priorities, the rigidity and the messianic attitude with which the reforms were implemented in Latin America, as well as their poor outcome. Something very different happened in Asia, where economic reforms were often intended (rightly or wrongly) as a more targeted and pragmatic mechanism to overcome specific economic and financial constraints. Instead of implementing reforms as a mechanism to reverse existing industrialisation strategies, in Asia they were put into practice in order to continue and strengthen ambitious processes of industrialisation.

Ilustração e interpretação textual: a arte como estratégia de ensino-aprendizagem na área de linguagens e códigos

Investiguei a arte como estratégia de ensino/aprendizagem e como esta prática estabelece quebra de paradigmas e incentivo à autonomia discente. Para tanto fiz uma breve descrição histórica acerca do panorama teórico correlacionado com o percurso das inovações educacionais desde o final da Idade Média até a contemporaneidade, buscando identificar de que forma o acúmulo teórico-metodológico gerado por este itinerário influenciou na disciplina Arte/Educação e no seu potencial inovador. Observei ainda como a ilustração textual, produzida pelos educandos, funciona como veículo de reelaboração crítica de suas realidades mediata e imediata. Esta investigação teve como sujeitos alunos do nono ano do Ensino Fundamental II, no decorrer de 2011, na escola autogestionária Waldorf Micael, em Fortaleza, Ceará, Brasil. Ao longo das observações, procurei responder às seguintes questões: De que maneira a ilustração textual se configura na qualidade de mediadora de processos interpretativos no contexto de ensino/aprendizagem em arte e literatura? De que forma, ela, no contexto da sistemática pedagógica, se revela como ferramenta de inovação pedagógica? Qual a sua importância no desenvolvimento do senso crítico do educando, e como tal fato se configura inovador? Como interfere na apreensão da realidade do educando, no seu aspecto estético, político e social? Os dados da investigação foram obtidos por meio de entrevistas, análise documental e observação participante; dessa forma esta pesquisa configurou-se como qualitativa, do tipo etnográfica e de base hermenêutica.
