“…These papers similarly impose a subsistence constraint within a modern growth model and allow for exogenous technological change in the agricultural sector. Gollin et al (2002) also use the model to interpret the evolution of international income differences. The main difference between our paper and these is that the earlier papers do not allow a feedback from industry to agriculture corresponding to the mechanization of farming.…”

This paper examines the effect of agricultural development on a country's overall development and growth experience. In most poor countries, large fractions of land, labor, and other productive resources are devoted to producing food for subsistence needs. This "food problem" can delay a country's industrial development for a long period of time, causing its per capita income to fall far behind the world leader. Once industrialization begins, this trend is reversed. The extent to which a country catches up to the leader depends primarily on factors that affect productivity in non-agricultural activities: agricultural productivity is thus largely irrelevant in the very long run. Terms of use: Documents inBut in the short run, a country that experiences large improvements in agricultural productivity (due to, say, a Green Revolution) will experience a rapid increase in its income relative to the leaders.

This paper develops two-sector general equilibrium models of urbanization, with and without equity consideration, respectively. It is shown that considering equity will result in a higher level of urbanization than otherwise, when urban inequality is sufficiently small or migration costs are sufficiently large. Such a theoretical prediction is confirmed by empirical modeling results using panel data from People's Republic of China (PRC). Provincial governments that paid attention to the inequality issue are found to have higher urbanization levels than those that did not.Finally, we explore possible equity consideration-to-urbanization transmission channels, and empirically establish that equity consideration in PRC (e.g., government initiatives towards combating rural poverty or the urban-rural gap) is positively correlated with road density, which helps reduce migration costs, and with bank lending to the manufacturing sector, which helps enhance the pulling force of migration. Thus, policymakers in the developing world should reverse their prevailing anti-urbanization attitudes and practices that tend to slow down urbanization or restrict rural-to-urban migration.

“…A maioria dos autores relata a tendência declinante da participação da agropecuária na composição do PIB de grande parte dos países do mundo, como por exemplo, Schultz (1951), Ahumada (1967), Araújo (1975), Araújo e Schuh (1988), Syrquin 4 (1988), Stern (1994), Alexandratos (1999), Gollin et al (2000) e Guilhoto (2004), associando essa tendência ao processo de desenvolvimento econômico.…”

“…Stern (1994 aponta a perda nos preços relativos (preços agropecuários / preços industriais) como a principal causa da redução da participação da agropecuária no PIB total de um país. Gollin et al (2000) relata que o desenvolvimento econômico-social ocorre com a liberação de mão-de-obra das atividades agropecuárias para as atividades urbano-industriais, gerando dessa forma rendas (produto) não oriundas da agropecuária, reduzindo a participação desta no total da renda gerada. Os autores comentam a necessidade de ganhos de produtividade na agropecuária para que essa continue fornecendo alimentos em abundância para a população que não está mais trabalhando nas atividades agropecuárias, concordando com Araújo e Schuh (1975), quando afirmam que outra característica importante do desenvolvimento é o crescimento da produtividade do trabalho e a diminuição da diferença desta entre os diferentes setores da economia.…”

Resumo: Este artigo faz uma análise da evolução da participação da agropecuária no PIB dos EUA de 1960 a 2001, dando destaque à análise econométrica das principais variáveis que determinam essa participação. A tendência geral, no período de 1960 a 2001, é a diminuição da participação da agropecuária no PIB. Porém, isto não ocorre de forma contínua, pois de 1971 a 1973 essa participação aumentou. O artigo prova, econometricamente, a quebra de tendência da participação da agropecuária no PIB de 1971 a 1973 e centra sua análise no período de 1973 a 2001. Através de gráficos, observa-se grande crescimento da produção física de cereais e de carnes no período de 1970 a 2001, que se explica pelo grande crescimento da produtividade da agropecuária e dos subsídios governamentais, dado que a tendência da relação de preços recebidos/ preços pagos pela agropecuária foi decrescente nesse período. Baseado em um modelo contábil que explicita as variáveis que determinam a participação da agropecuária no PIB, um modelo econométrico é definido e estimado. As principais variáveis determinando a participação da agropecuária no PIB dos EUA (em ordem decrescente de importância), no período de 1973 a 2001, são a relação de preços recebidos/preços pagos, o valor defasado dessa participação e a produtividade total dos fatores da agropecuária.
