Climate adaptation economics: Bibliometrics, methods, and mechanisms

Key findings from this study

• The authors propose that methodological approaches shifted from static to integrated, multi-method frameworks better capturing behavioral adaptation responses across households and firms.
• The review identifies that households and firms employ distinct adaptation strategies—consumption and agricultural changes for households versus diversification and innovation for firms—mediated by resource endowments and institutional context.
• The study found that theoretical progress clarified adaptation-mitigation interactions and adaptation finance's role in international climate cooperation, though vulnerabilities of specific regions remain empirically underdeveloped.

Overview

A systematic review and bibliometric analysis of 6,248 publications spanning 1978 to 2025 synthesizes the economics of climate adaptation, tracing research evolution, methodological approaches, and empirical findings on how households and firms respond to climate risks.

Methods and approach

The authors conducted a bibliometric analysis of peer-reviewed literature to map knowledge structures and research trends. They evaluated methodological approaches across the adaptation economics literature, assessing their capacity to capture behavioral responses, estimate causal effects, and model dynamic optimization. The review synthesized theoretical developments and empirical evidence on adaptation strategies across household and firm-level decisions.

Results

Households adapt through consumption adjustments, agricultural practice changes, and migration decisions. Firms employ product diversification, geographic relocation, supply chain reconfiguration, and technological innovation. Methodological approaches evolved from static frameworks toward integrated, multi-method analyses that combine experimental, quasi-experimental, and dynamic modeling techniques. The literature shift reflects growing recognition that single-method approaches inadequately capture complex adaptation responses.

Theoretical progress clarified interconnections between adaptation and mitigation policies, the role of adaptation finance in international climate cooperation, and welfare implications of market-driven versus policy-driven strategies. Resource availability, institutional quality, and behavioral constraints mediate adaptation outcomes across economic agents. Research frontiers remain underdeveloped in vulnerability assessment for specific regions and in long-term dynamic modeling frameworks that incorporate uncertainty.

Implications

Heterogeneity in adaptation responses across populations and sectors necessitates tailored policy approaches rather than uniform interventions. Resource-constrained economies and vulnerable regions require targeted adaptation assistance beyond current mechanisms. Integration of social and political economy dimensions into damage function specification and uncertainty modeling improves policy design and welfare assessment.

Future research advancing empirical identification of heterogeneous behaviors in vulnerable regions strengthens the evidence base for adaptation investment allocation. Network-based approaches and methodological innovation addressing dynamic long-term outcomes will enhance understanding of adaptation effectiveness and inform efficient resource deployment. Theoretical progress on damage functions and uncertainty treatment remains essential for robust cost-benefit analysis of adaptation strategies.
