Regime hídrico de alguns solos de Jaboticabal

Na caracterização hídrica dos solos do Campus da Faculdade de Ciências Agrárias e Veterinárias de Jaboticabal (SP), verificou-se que o Latossolo Vermelho eutroférrico típico apresentou maior capacidade de água disponível. A retenção da água, na capacidade de campo (0,01 MPa) e ponto de murcha permanente (1,5 MPa), correlacionou-se melhor com as frações argila e silte, em relação ao teor de matéria orgânica e densidade do solo. Utilizando características hídricas, como a capacidade de água disponível, foi estabelecido por meio do balanço hídrico de Thornthwaite o regime hídrico para os solos. Verificou-se a predominância do regime hídrico ústico em todos os solos (Latossolo Vermelho Nitossolo).

Do Agglomeration Economies Reduce the Sensitivity of Firm Location to Tax Differentials?

Recent theoretical work in economic geography has shown that agglomeration forces can mitigate 'race-to-the-bottom' tax competition, by partly or fully offsetting firms' sensitivity to tax differentials. We test this proposition using data on firm births across Swiss municipalities. We find that corporate taxes deter firm births less in more spatially concentrated sectors. Firms in sectors with an agglomeration intensity in the top quintile are less than half as responsive to differences in corporate tax burdens as firms in sectors with an agglomeration intensity in the bottom quintile. Hence, agglomeration economies do appear to attenuate the impact of tax differentials on firms' location choices.
