Baumgartner and Jones (1993) showed how radically new policies emerge on government agendas as a consequence of exogenous shocks to policy subsystems displacing privileged interests. But how do these policies evolve post-punctuation? In this paper, we present three different models of policy change. Policies may revert to the old status quo if displaced interests re-assert themselves, or they may be “locked-in” by new interests now reaping the benefits. Alternatively, they may incrementally change as lawmakers “learn” how to better meet target population needs, particularly by witnessing how other jurisdictions address similar problems. We test these models with data on change in state charter schools laws over time. We find that whether old status quos are overthrow, and the fate of charter policies when they are enacted, is influenced more by competing political interests, especially interest groups, than elite and public perceptions of broad systemic crises. Yet, we also find that changing demands on the state and learning from the successes and failures of neighboring states also play significant roles. 相似文献

Why were American officials caught by surprise with the military coup and later revolution in Iraq on 14 July 1958? Drawing on American intelligence and diplomatic records as well as multilingual sources, this article argues that the US intelligence failure is the product of two factors: the collection of information from too few and too similar human sources of intelligence in Iraq’s ruling regime, and the unreceptivity of US officials to assessing new information and their unwillingness to update assessments of local Iraqi developments. It revisits America’s intelligence failure in Iraq and suggests important lessons for the study of intelligence. 相似文献

Evidence is presented regarding strengths and limitations of portfolio approaches as applied to diversifying export earnings. An empirical application using data from Malawi, Tanzania, and Zimbabwe is used to demonstrate these strengths and limitations. Modifications of the typical portfolio approach to export diversification are presented; these modifications help make the approach more plausible for use in developing countries. The modified approach is shown to provide guidance to policymakers who seek simultaneously to increase export earnings and reduce their instability. 相似文献

The United States has faced at times the policy dilemma of seeing conflict erupt between two countries with which it maintains friendly diplomatic relations. The bureaucratic biases of relevant agencies can play an important role in determining whether to choose sides or remain neutral in these conflicts. In the early 1960s the Africa Bureau adopted a pro-Ethiopia bias that shaped American policy in the Horn of Africa. With the insights provided by the 2010 Wikileaks cables, this analysis explores how the “Ethiopia imperative” affected three inter-related American policy decisions in the Horn of Africa in the early twenty-first century: the decision to support Ethiopia despite its refusal to abide by a legally binding decision that favoured Eritrea following the 1998–2000 Eritrea–Ethiopia border war; to give Ethiopia what amounted to a “blank cheque” to invade Somalia in December 2006 and overthrow the Council of Islamic Courts (CIC); and to confront and isolate Eritrea diplomatically for waging proxy war against Ethiopia in Somalia. 相似文献
