We examine the association between calorie-based indicators and experiential indicators of food security using data from slum households of Kolkata surveyed in 2010–2011. Experiential indicator is constructed following the United States Household Food Security Survey Module. Calorie based indicator is constructed using household-specific calorie norms. Modelling techniques take account of potential endogeneity in the relationship. The two indicators are aligned in the same direction implying more accurate targeting. However, there is a lack of one-to-one correspondence between the two measures and the drivers of calorie deprivation and food insecurity also differ, suggesting a one-size-fits-all policy cannot address both concerns simultaneously. 相似文献

Discovering the Dark Side of Power: The Principal’s Moral Hazard in Political-Bureaucratic Relations
Marian Döhler 《国际公共行政管理杂志》2018,41(3):190-202
Principal agent (PA) is among the most prominent concepts for analyzing the relationship between politics and bureaucracy. Nonethelesss, the inherent bias of PA scholars to attribute moral hazard almost exclusively to the agent, usually referred to as “bureaucratic drift”, requires re-examination. Building on the spare literature in which moral hazard of the principal is considered, this paper provides empirical evidence for a neglected aspect of the PA concept. Three cases of German regulatory agencies responsible for drug control, financial services and rail safety are analyzed in critical situations which were largely perceived as bureaucratic failures. The analysis reveals that a good deal of these failures, ranging from negligence to suppressing crucial information, has to be attributed to the political principal. This is called the dark side of power because the intention is to shift blame or to dodge political responsibility. Turning conventional PA reasoning upside down, the conclusion is that the principal’s moral hazard should be considered more routinely as a potential explanation for political-bureaucratic interactions. 相似文献

An ongoing debate among policymakers and terrorism scholars concerns the effectiveness of deterrence as a counterterrorism tool. Absent from the debate is a discussion of the complex nature of terrorist decision making. Decisions are made at varying levels in a terrorist organization, often by actors having different motives, resulting in behavior that is not always fully rational. This article identifies several circumstances when terrorist behavior is not the product of an entirely unitary, rational decision-making process, and therefore highlights when deterrence policies will be least effective. It concludes with some policy implications for understanding when deterrence policies are most likely to succeed and how to address terrorism in other situations. 相似文献
