Theories Of Policy Diffusion

Policy diffusion is the idea that the policy decisions of one place influence the policies of another place. While policies can diffuse because the policies are effective and popular, the reality of policy decision making is often much more complicated. A variety of factors can influence how a policymaker selects what policies. This memo will outline how policies diffuse by exploring some of the various factors-or mechanisms-that enable policy diffusion. While numerous mechanisms can encourage a policy's diffusion, this memo focuses on the mechanisms that are most prominent in education policy, including problem definition and policy entrepreneurs. Finally, we'll explore how these mechanisms can shift depending on the varied contexts of policy …show more content…

Policy development is often portrayed as starting with a specific, objective problem that is then addressed by policies that are meant to perfectly address those problems (Lindblom, DATE). However, in reality, the resources available to policymakers are limited and access to information is finite. Consequently, policy development depends on a problem definition that is subjective and shifts as value goals are leveraged (Lindblom, DATE). The subjective nature of a problem definition is critical to policy diffusion because certain policies are more or less appropriate for certain problems. If a policymaker's decisions are based on a flexible and changing problem definition, then policies are selected not based on research and empirical evidence but are more often selected based on a variety of influencing factors. This is an important aspect of policy diffusion because it means that the vast adoption of a policy is not because a policy particularly good or effective, but because a variety of factors enabled the spread of that …show more content…

As Craig Volden suggests, isolating diffusion mechanisms is difficult (2010). Policymakers might identify problems and determine solutions based on the influence of policy entrepreneurs, but other external pressures are also influential in the decisions of policymakers. Some policies diffuse because policymakers are left with few policy options. In those instances, the line between volunteerism and cohesion is muddled. This can be seen in the national adoption of 21 as the national drinking age. While state policymakers could technically choose to make 21 the legal drinking age, those states would lose federal funding for highways. Thus, the national drinking age policy diffused because state policymakers were left with few alternatives. However, policies are often diffused through multiple policy mechanisms that work simultaneously rather than diffusing through one mechanism alone. For example, in their study of performance-accountability policies in higher education, Michael McLendon et. al. examined several mechanisms that enabled the diffusion of these policies. Their study found that states with a larger Republican legislative presence were more likely to adopt these performance-accountability policies-possibly due to the fact that it is politically advantageous for Republican policymakers to support these policies (DATE). That political gaming is
