Darkwah, A.B., Shaffer, B. and Hastings-Simon, S., 2026. Layering incentives: The impact of local top-ups on solar adoption and welfare. Energy Policy, 217, p.115427.
Abstract: This paper investigates the effect of a local “top-up” to an existing solar rebate program in Alberta. Specifically, we examine whether providing additional financial incentives at the local level increases adoption rates and generates meaningful public welfare benefits. Using a difference-in-difference framework, we find that the incidence of the top-up is fully passed through to consumers, resulting in a 72\% increase in solar installation rates. Our welfare analysis, using the Marginal Value of Public Funds (MVPF), also reveals that the societal benefits of the top-up exceed its costs, yielding a favorable return on public investment. These findings suggest that local top-ups can be an effective tool for increasing renewable energy adoption and enhancing public welfare, offering important insights for policymakers.
Resource Revenue Sharing Agreements" with Lucija Muehlenbachs \& Laurel Wheeler, Forthcoming in the Canadian Public Policy/ Analyse de Politiques
Abstract: A growing number of First Nations across Canada are entering into agreements with provincial governments to share revenues from natural resource extraction within their traditional territories. Yet, little guidance exists on the design of these Resource Revenue-Sharing Agreements (RRSAs). In this paper, we examine publicly available RRSAs to summarize their common components. We outline the decision points involved in structuring an RRSA and discuss potential benefits and drawbacks for First Nations considering entry.
Works in Progress
Abstract: I analyze the effectiveness of Canada's first greenhouse gas pricing policy in reducing emissions in the electricity market and assess the role of market power in influencing these outcomes. I find that although increasing the stringency of the policy significantly reduced emissions, the presence of market power among large firms mitigated these benefits. Specifically, strategic behavior by firms induced gas-to-coal switching, thereby limiting the intended emissions reductions. These findings highlight market power as a factor that could impede or slow the decarbonization of the electricity sector.
