The interactive effects of policies: Insights for policy feedback theory from a qualitative study on homelessness

by Anna Kopec

Existing policy feedback literature on participation examines how policy designs shape political behavior and argues that policies can encourage some people to participate whilst discouraging others. This prompts the inquiry: how do the effects of policy design characteristics interact? How might the positive effects of one element of a policy, for example, interact with the negative effects of another to influence participation of a marginalized group? How might multiple negative or positive effects influence participation? To explore these complex effects, this study compares how homelessness policies affect political engagement in Melbourne, Australia, and Toronto, Canada.

Drawing on 118 qualitative interviews with individuals experiencing homelessness, service providers, and policymakers, this comparative study explores how the effects of policy design characteristics (i.e., distribution of benefit, generosity, eligibility, visibility, delivery design, and integration) work together to either mobilize or discourage political engagement. Table 1 defines these terms below:

Figure 1 demonstrates how the interaction of multiple policies, through their design characteristics, influences political participation. These effects are shaped by the resources allocated, the signals policies send about individuals’ roles in society, and their broader impact on institutional capacity to facilitate engagement.

The qualitative interview data reveals diverse service access among participants, highlighting key variations in characteristics, particularly visibility, delivery, and integration. Table 2 outlines the policy areas by city and sector, detailing policy characteristics and their effects on engagement as reported by participants. While both cities have many negative policy effects, Melbourne’s housing and health policies showed more positive impacts, particularly in integration, visibility, and delivery.

Notably, Table 3 illustrates that individuals experiencing homelessness actively engage in various efforts to drive change. While 56-64% of participants reported voting in their last federal election, over 90% engaged in actions such as peer work, providing organizational feedback, and joining advisory groups.

The way in which different policy design characteristics interact can either amplify exclusion or help counteract it, depending on how services are structured and delivered. For example, integrated service delivery can moderate the negative effects of means-tested programs with strict eligibility rules. In Melbourne, social workers traveling to service centers helped reduce barriers related to eligibility and stigma. In contrast, Toronto’s lack of visibility and integration often left participants feeling isolated.

Policy feedback scholars must pay closer attention to the lived experiences of marginalized populations. These perspectives reveal how policy design and the interplay of its characteristics directly shape political participation. Without this understanding, we risk overlooking the conditions under which participation influences policy or the ways we might create spaces that meaningfully support civic engagement.

This research highlights how policies are structured and delivered, not just how their content affects democratic engagement. Integrated, visible services can empower marginalized individuals to engage politically, even amid social and economic instability.

For marginalized and targeted populations, policy design can dictate their civic participation and relationship with the state. Too often, policies reinforce exclusion, further distancing individuals from decisions that directly impact their lives. By examining where and how these populations participate, we gain critical insight into whether their voices are meaningfully reflected in future policymaking.

About the Author

Anna Kopec is an Associate Professor at the School of Public Policy at Carleton University. Her research agenda examines the relationship between political participation and public policy among marginalized populations in Western welfare states. How do policy designs influence the political agency of vulnerable groups, and how in turn do such groups participate to bring about changes to the policies and systems they interact with? This comparative work focuses on populations experiencing homelessness. A secondary research agenda examines intersectionality and homelessness, with a consideration of how policies and services individuals access influence how certain communities participate.
