    • Defining the economic scope for ecosystem-based fishery management

      Reimer, Matthew (Proceedings of the National Academy of Sciences of the United States of America, 3/5/2019)
      The emergence of ecosystem-based fisheries management (EBFM) has broadened the policy scope of fisheries management by accounting for the biological and ecological connectivity of fisheries. Less attention, however, has been given to the economic connectivity of fisheries. If fishers consider multiple fisheries when deciding where, when, and how much to fish, then management changes in one fishery can generate spillover impacts in other fisheries. Catch-share programs are a popular fisheries management framework that may be particularly prone to generating spillovers given that they typically change fishers� incentives and their subsequent actions. We use data from Alaska fisheries to examine spillovers from each of the main catch-share programs in Alaska. We evaluate changes in participation�a traditional indicator in fisheries economics�in both the catch-share and non�catch-share fisheries. Using network analysis, we also investigate whether catch-share programs change the economic connectivity of fisheries, which can have implications for the socioeconomic resilience and robustness of the ecosystem, and empirically identify the set of fisheries impacted by each Alaska catch-share program. We find that cross-fishery participation spillovers and changes in economic connectivity coincide with some, but not all, catch-share programs. Our findings suggest that economic connectivity and the potential for cross-fishery spillovers deserve serious consideration, especially when designing and evaluating EBFM policies.
    • Fisheries Production: Management Institutions, Spatial Choice, and the Quest for Policy Invariance

      Reimer, Matthew; Abbott, Joshua; Wilen, James (University of Chicago Press Journals, 2017-04-01)
      The fishery-dependent data used to estimate fishing production technologies are shaped by the incentive structures that influence fishermen’s purposeful choices across their multiple margins of production. Using a combination of analytical and simulation methods, we demonstrate how market prices and regulatory institutions influence a dominant short-run margin of production—the deployment of fishing time over space. We show that institutionally driven spatial selection leads to only a partial exploration of the full production set, yielding poorly identified estimates of production possibilities outside of the institutionally dependent status quo. The implication is that many estimated fisheries production functions suffer from a lack of policy invariance and may yield misleading predictions for even the most short-run of policy evaluation tasks. Our findings suggest that accurate assessment of the impacts of a policy intervention requires a description of the fishing production process that is sufficiently structural so as to be invariant to institutional changes.
    • Identifying the Potential for Cross-Fishery Spillovers: A Network Analysis of Alaskan Permitting Patterns, Working Paper, Resources for the Future

      Addicott, Ethan T.; Kroetz, Kailin; Reimer, Matthew; Sanchirico, James N.; Lew, Daniel K.; Huetteman, Justine (Resources for the Future, 2016-12-01)
      Many fishermen own a portfolio of permits across multiple fisheries, creating an opportunity for fishing effort to adjust across fisheries and enabling impacts from a policy change in one fishery to spill over into other fisheries. In regions with a large and diverse number of permits and fisheries, joint-permitting can result in a complex system, making it difficult to understand the potential for cross-fishery substitution. In this study, we construct a network representation of permit ownership to characterize interconnectedness between Alaska commercial fisheries due to cross-fishery permitting. The Alaska fisheries network is highly connected, suggesting that most fisheries are vulnerable to cross-fishery spillovers from network shocks, such as changes to policies or fish stocks. We find that fisheries with similar geographic proximity are more likely to be a part of a highly connected cluster of susceptible fisheries. We use a case study to show that preexisting network statistics can be useful for identifying the potential scope of policy-induced spillovers. Our results demonstrate that network analysis can improve our understanding of the potential for policy-induced cross-fishery spillovers.
    • Mechanisms matter for evaluating the economic impacts of marine reserves

      Reimer, Matthew (ScienceDirect, 2018-03-01)
      Large areas of marine and coastal environments have been protected to satisfy diverse policy goals, but there has been limited work understanding the economic impacts of such closures. While methods for establishing causal impacts are prevalent, less attention has been paid to explaining the mechanisms through which the causal relationship came to be. Understanding mechanisms is crucial for designing policies that foster the mechanisms that achieve the intended objectives of marine reserves and mitigate the mechanisms that do not. We estimate the treatment effect of a large marine reserve on the net earnings of a commercial fishery using difference-in-differences and synthetic-control designs, and decompose the treatment effect into its constituent mechanisms through structural equation modeling. We find minimal evidence that closing the marine reserve to fishing had a significant economic cost for the industry; however, several counteracting mechanisms are critical for explaining the effect and for generalizing to other settings.
