While the fertility effects of improving teenagers’ access to contraception are theoretically ambiguous, most empirical work has shown that access decreases teen fertility. In this paper, we consider the fertility effects of access to condoms—a method of contraception not considered in prior work. We exploit variation across counties and across time in teenagers’ exposure to condom distribution programs in schools. We find that access to condoms in schools increases teen fertility by about 12 percent. The results suggest that the effects of condom access varied significantly across different programs; the positive fertility estimates are driven by communities where condoms are provided without mandated counseling. Programs that mandated counseling have zero or negative fertility effects, but estimates on these counties are less robust across specifications.  相似文献

In this Special Section, this article reviews South Korean views on Japan's ‘peace’ Constitution and the Abe government's attempts at constitutional reform. It identifies three different understandings among South Korean academics on why Japan is escalating attempts to revise the Constitution under the Abe government. An in-depth analysis demonstrates that all three perspectives pay specific attention to Japan's constitutional reform in relation to security policy changes. However, they differ in assessing the impact of Japan's constitutional reform on South Korea as well as how South Korea should deal with such a change. A minority opinion considers Japan's ‘remilitarisation’ through constitutional revision as conducive to South Korean security interests by increasing deterrence against North Korea, whereas the dominant opinion is that any attempt to revise the Constitution could be in and of itself a potential threat to South Korea's security due to a lack of trust attributed to unresolved historical conflicts between Korea and Japan. However, all three approaches pay hardly any attention to the positive role of Japan's peace Constitution while Japan's peace Constitution might provide a regional peace model in Northeast Asia.  相似文献

Contemporary urbanization in the Global South merits greater attention from scholars of comparative politics. Governance, associational life, and political behavior take distinctive forms in the social and institutional environments created by rapid urbanization, particularly within informal settlements and labor markets. In this special issue, we examine forms of collective action and claims-making in these spaces. We also consider how the state assesses, maps, and responds to the demands of informal sector actors. Tackling questions of citizen and state behavior in these informal urban contexts requires innovative research strategies due to data scarcity and social and institutional complexity. Contributors to this symposium offer novel strategies for addressing these challenges, including the use of informal archives, worksite-based sampling, ethnographic survey design, enforcement process-tracing, and crowd-sourced data.  相似文献

O’Donnell analyses the confluence of Islamophobia and anti-government conspiracy theory in the works of the far-right think tank, the Center for Security Policy (CSP). He argues that, rather than only being a contemporary form of the religious and racialized demonologies that code ‘Islam’ as being the constitutive outside of ‘the ‘West—irrational, religious and authoritarian versus rational, secular and democratic—Islamophobic conspiracism should also be examined in the context of anxieties over the erosion of personal and state sovereignty under neoliberalization. Mobilizing an Islamophobic demonology that constructs ‘Muslims’ as inassimilable to ‘American’ subjectivity, the CSP's Islamophobic conspiracism projects this construction of absolute alterity on to American social and state systems. In doing so, O’Donnell contends, Islamophobic conspiracism takes neoliberalization's estrangement of the state and its citizens to its logical conclusion, transfiguring the societal processes that impact on the freedom of the individual—notably the state and civil society—into something inassimilable to that individual's claims to self-ownership and self-mastery.  相似文献

When agencies regulate, they must calculate the costs and benefits of their regulations. To do this, they must often price non-market goods—for instance, the value of protecting wildlife or the environment. Regulators have typically relied upon contingent valuation surveys to put prices on these types of goods. But contingent valuation surveys are fraught with error and often give rise to implausible valuations that cannot be trusted. Quadratic voting offers a better solution. Agencies should hold quadratic votes over nonmarket goods and use those votes to price the goods at issue.  相似文献
