European Policy Analysis references for defining the identity of one policy versus another, hence delineating the boundaries of policies. First and most fundamentally, a policy can be described as a certain ensemble of substantive problems, goals, and means. Problems, conceived of as perceived difference between a given and a desired state of the world, mark the starting point of a certain policy and policy actions (Dery 1984; Hoppe 2011). Policy goals specify an envisioned end state of policymaking; and a policy tool (as the means) comprises a set of interventions that is expected to transform a policy problem into a policy solution. These substantial policy elements span two mutually constitutive layers, which can be considered policy-related excerpts of the subjective and objective worlds (Majone 1980). Policies are usually written in some form of (symbolic) policy text (such as a bill, a law, a regulation, or a manifesto). These policy texts are interpreted and enacted in some form of (material) policy action “on the ground” (such as the allocation of resources to build an infrastructure and so forth). Second, the social dimension of a policy reflects the assumption that “public policy is a matter of human agency” (Schneider and Ingram 1997, 1). Following this, the policy substance (problems, solutions, and means) cannot be meaningfully understood in isolation from the actors who make and interpret a policy. These actions take place in some form of policy arena (Ostrom 1999), which includes various kinds of actors who are part of specific, more complex actor constellations, and engage with one another in various spheres that are characterized by either “opening” (debates) or “closing” (decisions) forms of interactions (Scharpf 1997; Stirling 2008). Third, the temporal dimension reflects the widespread assumption that a policy is not a singularity or a static entity. Rather than a “still,” a policy is understood as a “movie” (Kay 2006), implying that its substantial elements and social arena evolve over time as a sequence of different temporal states. Most prominently, this notion has been expressed in models such as the policy cycle (Jann and Wegrich 2007) or other temporal ideas highlighting the chaot ic and contingent character of policy developments (Kingdon 2014; Zahariadis 2007). These different policy temporalities can be captured according to more general, time-related criteria (Pierson 2004; Prittwitz 2007), such as duration, dynamics, or velocity. Similar to time, the spatial dimension of a policy is fundamental as it underlies the other dimensions. Most prominently, the notion of policy space is reflected in concepts, such as multilevel policymaking, suggesting that a policy may extend over several functional or jurisdictional levels of governance (Piattoni 2010). The many ways of thinking about and conceptualizing policy space can be reduced to two: a vertical subdimension covering various policymaking levels that are related in some form of hierarchical order (from the local to the international) and a horizontal one referring to various policy areas at a certain level, which are demarcated by jurisdictional borders. The second question (How are policies integrated?) relates to the modes of policy integration and can be approached by more closely looking at the meaning of “integration.” Following a generic understanding, “integration” 181
