Inverse Productivity or Inverse Efficiency? Evidence from Mexico 总被引:2,自引:0,他引:2
Using a unique panel data set from rural Mexico, we find strong evidence of a negative relationship between farm size and both productivity and technical efficiency: large farms not only have a lower value of output per hectare than small farms, they also produce further from the efficiency frontier. Our findings suggest that, in spite of the ongoing transformation of agricultural supply chains and economists’ recommendations for small farmers to exit crop production, there may be sustained advantages for smallholder farms. Our analysis offers new insights into inverse-farm size relationship, the productivity–efficiency relationship, and the use of stochastic frontier techniques. 相似文献

Edward Comor 《国际研究季刊》2001,45(3):389-408
The author examines the concept of global civil society (GCS) through the use of theoretical tools and empirical evidence related to the study of International Communication. He demonstrates that scholarship on GCS tends to simplify the process through which information becomes knowledge and that the state system–GCS relationship often is presented in terms of an ahistorical power dichotomy. In relation to these problems, what the author calls GCS progressives tend to underplay political-economic factors shaping GCS, including the implications of structural power; they tend to emphasize the importance of spatial integration while neglecting related changes in temporal norms; and, more essentially, they often under-theorize the importance of socialization processes and relatively unmediated relationships in the ongoing construction of reality. The author concludes that through a more focused analysis—concentrating on how new technologies can be used to organize nationally and locally, and on lifestyle changes associated with communications developments—more precise analyses and fruitful strategies for GCS progressives may emerge. 相似文献

This study interviewed 350 African immigrants in North Carolina (NC) to shed light on their economic conditions. It focused primarily on their labor force participation and incomes for the period 2004–2014. The findings showed that both structural changes in NC's economy and prejudicial experiences within the labor force were the most important forces that undermined the economic ambitions of the Africans. The study also yielded a complex picture and raised some questions about the resettlement outcome of African immigrants in the United States. 相似文献
