This paper presents a new model incorporating features of developing country agriculture likely to shape the welfare outcomes of alternative agricultural policies. The model features heterogeneous households linked through markets in a rural economy-wide structure, with endogenous market participation for farmers facing transactions costs. We use it to simulate the impacts on rural welfare of market price supports, production subsidies, input subsidies, and the removal of transaction costs. Applications to six countries demonstrate the diversity of potential impacts, exhibit some systemic differences compared with impacts in developed countries, and identify specific circumstances under which market interventions may be only slightly less efficient than direct payments at transferring incomes to rural households.  相似文献

We adapt the models of Menzio and Moen (2010) and Snell and Thomas (2010) to consider a labor market in which firms can commit to wage contracts but cannot commit not to replace incumbent workers. Workers are risk averse, so that there exists an incentive for firms to smooth wages. Real wages respond in a highly nonlinear manner to shocks, exhibiting downward rigidity, and magnifying the response of unemployment to negative shocks. We also consider layoffs and show that for a range of shocks labor hoarding occurs while wages are cut. We argue these features are consistent with recent evidence. (JEL E32, J41)  相似文献

This study uses state‐level panel data from a 33‐year period to test the hypotheses of offsetting and enhancing behavior with regards to motorcycle helmet legislation. Results presented in this article find no evidence of offsetting behavior and are consistent with the presence of enhancing behavior. State motorcycle helmet laws are estimated to reduce motorcycle crashes by 18.4% to 31.9%. In the absence of any behavioral adaptations among motorcyclists mandatory helmet laws are not expected to have any significant impact on motorcycle crash rates. The estimated motorcycle crash reductions do not appear to be driven by omitted variable bias or nonclassical measurement error in reported crashes. Overall, the results strongly suggest that mandatory helmet laws yield significant changes in motorcycle mobility in the form of reduced risk taking and/or decreased utilization.  相似文献

This paper analyzes the role of propaganda use in cyberterrorism. The main premise is that cyberterrorists display various semiotic gestures (e.g., the use of images and Internet videos) to communicate their intents to the public at large. In doing so, they communicate themes??these themes range from hate to anger. Cyberterrorism, then, is a form of theater or spectacle in which terrorists exploit cyberspace to trigger feelings of panic and overreaction in the target population. In many cases, this form of propaganda is the primary means of communication for various cyberterrorist groups to convey their intents. Internet sites also produce numerous opportunities for in-group communication and publicity.  相似文献

The best-known and most influential cinematic image of Scotland is that which constructs the country as the civilised modern world’s northern boundary and ideological antithesis. This historically venerable representational tradition incorporates Brigadoon (d. Vincente Minnelli, USA, 1954), Brave (d. Mark Andrews/Brenda Chapman/Steve Purcell, USA, 2012) and much else in between. The following essay examines what is perhaps the most explicit and extended twenty-first century manifestation to date of Scotland’s classic celluloid stereotype: the oeuvre of British popular genre filmmaker Neil Marshall. Analysis of this director’s Scottish trilogy – Dog Soldiers (GB/Lux/USA, 2002), Doomsday (GB/USA/SA/Ger, 2008), and Centurion (GB/Fr, 2010) – suggests not simply the historical persistence of a particular cultural representation of a particular national culture and identity, but also the varied, and often non-nationally specific, thematic uses to which Scottish cinematic stereotypes can be and are put. That conclusion suggests a number of possible future directions for Scottish cinema criticism more generally. First, the need for a more inclusive critical engagement with popular genre cinema, a hitherto under-examined area with the study of Scotland’s relationship with the moving image. Second, the extent to which critics might usefully approach Scottish-set and -themed cinema in a more multifaceted manner than has frequently been the case in historical terms. Neil Marshall’s oeuvre exemplifies the complex interplay of nationally and non-nationally specific images and ideas that exist within many popular filmic representations of Scotland.  相似文献

Prisoner reentry has received great interest in political sociology, criminology, and beyond. Research documents the struggles of individuals trying to find their way back into society. Less attention has been given to the organizational aspects of reentry. This is unfortunate given the rapid growth of nonprofit reentry organizations in the United States, which introduces a new set of questions about the context and challenges to prisoner reentry. Drawing on an ethnography of Safe, a nonprofit reentry organization in the Northeast, I describe the organization's pivotal role in institutionalizing the pathway to prisoner reentry: a road to reentry, which takes former prisoners through a process that reconfigures their morality, identity, and social relationships. The road‐to‐reentry concept helps bring together scholars of the welfare state and criminology by highlighting how the challenges of prisoner reentry rely on how this process is organized. The way in which prison reentry is organized, in turn, affects former prisoners’ agency and shapes the relationship between these men and women and their respective families and communities.  相似文献

Import Security: Assessing the Risks of Imported Food   总被引:1,自引:0,他引:1       下载免费PDF全文
We use data on food import violations from the FDA Operational and Administrative System for Import Support (OASIS) to address rising concerns associated with imported food, quantify import risks by product and by country of origin, and explore the usefulness of OASIS data for risk assessment. In particular, we assess whether there are significant trends in violations, whether import violations can be used to quantify risks by country and by product, and how import risks depend on economic factors of the country of origin. The results show that normalizing import violations by volume of imports provides a meaningful indicator of risk. We then use regression analysis to characterize import risks.  Using this model, we analyze import risks by product type, violation type, and economic factors of the country of origin.  We find that OASIS data are useful in quantifying food import risks, and that the rate of refusals provides a useful decision tool for risk management.  Furthermore, we find that some economic factors are significant indicators of food import risk by country.  相似文献

ABSTRACT

This paper argues that contemporary child and youth experiences of globalization call for retheorizing global justice around a new concept of empowered inclusion. The first part of the paper examines three case studies in globalization – child labour movements, child and youth migration, and young people’s organization around climate change – and shows how, in each case, young people, through their struggles against injustice, are simultaneously disempowered and empowered by their deep global interdependency. The second part proposes new theoretical advances in global justice that better respond to child and youth experiences through a childist concept of the empowered inclusion of both children and other marginalized groups. And the third part advances some preliminary suggestions about how a more child-responsive conception of global power and justice might be operationalized in practice across global policies, institutions, and culture.  相似文献
