Abstract The elasticity of aggregate supply cropland is one key to understanding the degree which policy‐induced increases in demand for biofuel feedstocks or agricultural CO 2 offsets will result higher prices expanded crop production. We report land elasticities United States and Brazil estimated directly from recent changes planted acreage expected returns. resulting implied land‐use with respect price are quite inelastic have declined sharply years. imply that current estimates...
The use of agricultural-based biofuels has expanded. Discussions on how to assess green house gas (GHG) emissions from biofuel policies, specifically (non-observed) land-use change (LUC) effects involve two main topics: (i) the limitations existing methodologies, and (ii) isolate biofuels. This paper discusses methodologies currently used by policy-makers take decisions quantify LUCs owing production expansion. It is our opinion that concerns regarding GHG associated with should focus...
Abstract: This paper aims to develop new methodology for the Brazilian beef and dairy sectors incorporating different levels of productivities in Land Use Model (BLUM), analyzing land use dynamics. Several datasets combinations were used supply demand equations re-estimated. Historical database developed this shows that livestock sector increased productivity per hectare (in both sectors), being an important releaser other agricultural uses. Even frontier regions, occupation process was...
O presente artigo analisou se há convergência do PIB per capita das microrregiões paranaenses utilizando as metodologias de β-convergência e σ-convergência citados em Barro & Sala-i-Martin (1995). Pode-se afirmar que, no período 1970 a 2002, houve significativa dessas regiões uma velocidade 4,92% ao ano mais pobres reduzirão metade dessa diferença renda quatorze anos. Esses resultados foram fortalecidos pelo teste σ-convergência, pois variância (em ln) reduziu-se significativamente...
