From systemically dispossessing Indigenous people of their territory for Euro-American settlement to routinely denying African American farmers operating loans in the 20th century, the US government's complicity in creating racial hierarchies in terms of land access is well documented. Less understood is how land policies oriented towards racial equity, namely, the Justice for Black Farmers Act (JBFA), and other initiatives that deal with land access as well as addressing racism more broadly, emerged during recent decades. In this article, we argue that such initiatives resulted from Black-led organizations and other farmer advocacy allies responding to neoliberal policy reforms. Concretely, even as these reforms destabilized farm economies, they also led to a decentralization of agricultural policy administration, which, in turn, created opportunities for community-based organizations to influence land governance. We make this argument after presenting a three-part periodization of the evolution of US land policy, starting with the emergence of racial hierarchies, then the period of partial reforms that began during the New Deal and, finally, the era of neoliberal reform.  相似文献

When and why did Sterling Area countries stop holding sterling as the majority of their foreign exchange reserves? This paper takes a comparative approach to examine the relative importance of various determinants of adherence to sterling in its declining years as an international currency. Using an original cross-national panel dataset covering the period 1965–79, we conduct survival analysis which systematically evaluates a comprehensive set of economic and political factors, at the country level as well as in international relations, about when and why countries chose to diversify their reserves away from sterling. Our results highlight the significance of international transactional factors in influencing adherence to sterling, while the effects of British geopolitical retrenchment, Commonwealth cultural ties, and distributional issues were more ambiguous and sensitive to local conditions. We also find that domestic political and historical factors, such as democracy and imperial legacy, played a role in sterling's international unravelling. Finally, we use our results to examine the experience of individual sterling countries and their decisions to diversify.  相似文献

Smallholder agriculture in sub-Saharan Africa is commonly characterised by high levels of technical inefficiency. However, much of this characterisation relies on self-reported input and production data, which are prone to systematic measurement error. We show theoretically that non-classical measurement error introduces multiple identification challenges and sources of bias in estimating smallholders' technical inefficiency. We then empirically examine the implications of measurement error for the estimation of technical inefficiency using smallholder farm survey data from Ethiopia, Malawi, Nigeria and Tanzania. We find that measurement error in agricultural input and production data leads to a substantial upward bias in technical inefficiency estimates (by up to 85% for some farmers). Our results suggest that existing estimates of technical efficiency in sub-Saharan Africa may be severe underestimates of smallholders' actual efficiency and what is commonly attributed to farmer inefficiency may be an artefact of mismeasurement in agricultural data. Our results raise questions about the received wisdom on African smallholders' production efficiency and prior estimates of the productivity of agricultural inputs. Improving the measurement of agricultural data can improve our understanding of smallholders' production efficiencies and improve the targeting of productivity-enhancing technologies.  相似文献
