This paper aims to test the effects of social interaction and input spillovers on the agricultural performance of family farms in mixed paddy rice production (organic and conventional farming). Using survey panel data from a Chinese village, we adopt a Spatial Durbin Model (SDM) derived from spatial econometrics to disentangle the social interaction effect from spillover effects and to control for technological heterogeneities. Our analysis reveals a negative social interaction effect indicating that an increase in the yield of neighbouring plots leads to a decrease in the yield of the plot itself. We also find input spillovers. Labour, capital costs, water and organic pesticides have positive spillovers while external nutrients (nitrogen and phosphate) have negative spillover effects. Our study thus calls for a better understanding of social interactions and spillover effects among farmers in the promotion of sustainable family farming. 相似文献

This article discusses the development of Berber literature in Morocco and the connections between this literature and Moroccan national identity as well as the pan-Amazigh identity movement. Over the last 40 years, the political conjuncture in Morocco has led Berber writers to affirm an alternative definition of Moroccanness, not exclusively based on Arabness, but one in which Berberity is included. This article aims to shed light on modern Berber literature, and on the social space in which it is embedded. It argues that there is no autonomous Berber literary field, the literature being intrinsically bound up with identity issues, but a Berber literary space, located at the intermingling of several fields (the political field and the field of language production in particular). The article first reconstructs the Moroccan political context by exploring the Amazigh movement, its aspirations and its reality. It then focuses on the relationship between the language issues (alphabet, standardization, etc.) and the emergence of a Berber “neo-literature.” Lastly, it moves beyond Morocco into the wider pan-Berber world – the Maghreb and those countries to which Berbers have emigrated – to question the possibility of a transnational Berber literature. 相似文献

AbstractA basic trade-off in military cooperation exists: States must respond to the dominant ally’s demands and act as a reliable partner while simultaneously making a decision that is acceptable to domestic audiences. We argue that compensatory burden-sharing strategies are imperfect but dependable solutions to manage foreign policy decisions at the domestic and alliance levels. Our theoretical expectations are tested using the US-Japan and US-Republic of Korea alliances and, in particular, the contribution of each country to the war in Afghanistan. We find that foreign aid commitments to third parties are made as a form of compensation when alliance expectations are substantial, but the secondary ally's ability to contribute militarily is highly constrained. Foreign aid has therefore served as an alliance management tool. 相似文献

Specialized literature has analyzed the impact of changes to fiscal institutions such as The National System of Fiscal Coordination (1980) and the constitutional reforms of article 115 (1983 and 1999) on the degree of financial dependence of local (municipal) governments and the governmental functioning. Political environment as well, affects to an important extent such functioning. Indeed, previous studies in the field of political economy point to the effects of political environment and fiscal institutions -such as public spending and debt- on national and sub-national governments. Based on four variables -political affiliation of the mayor, political affiliation of the governor, composition of local congresses and celebration of local elections-, the authors build indicators of “political confluence” at the municipal level. They study the effect that the degree of political unification at the municipal level has on the financial dependence with respect to the State government, and also to the local Congress. In their analysis, the authors also consider the political affiliation of the mayor and the local electoral cycle. Through its analytical focus and main empirical findings, this article contributes to broadening the scope of empirical studies of municipal financial dependence. Simultaneously, it adds to existing literature in the field of political economy that accounts for public finances at the sub-national level 相似文献

Over the last thirty years, Mexico has undergone an important consolidation of its institutional framework, focused primarily on the electoral and political system. This process of political change was accompanied by a significant transformation and liberalization of the financial and economic system. Mexico’s current situation proves that both processes do not yield satisfactory results when social problems are left unattended. In fact, the transition from a noncompetitive political system to a more democratic one, has not guaranteed better living conditions for most of the population, in part because there is practically no participation in public life on behalf of most of the citizenry. This article reflects on the fundamental importance of citizens’ participation in democracy. Particular attention is paid to public participative budgets as factors which may contribute to democracy’s consolidation and quality, but which have had negligible impacts thus far as is illustrated by public participative budgets initiatives that have been held in Mexico City. 相似文献
