This article argues that process tracing is a viable and suitable methodological alternative to probe the implications of formal models specifying how the dynamics of belief formation may systematically cause bargaining failures under uncertainty. I illustrate the argument with a brief case study of the failure of the European Defence Community in postwar Europe.

This article argues that process tracing provides a useful, although underestimated, avenue for empirically testing deductive game theoretical arguments. In-depth case analysis allows for a systematic evaluation of the crucial assumptions underlying the models and for making internally valid measurements of the model's core concepts. Furthermore, process tracing enables the researcher to overcome the weak conceptions of processes encountered in many game theoretic arguments. After outlining the usefulness of combining deductive game theory and process tracing, as well as discussing the limits of such an approach, the article illustrates the argument with an example from substantive research on civil–military relations in new democracies.

Although having been practised in the Social Sciences for decades, it was only in recent years that process tracing has gained prominence in methodological debates in political science. In spite of its popularity, however, there has been little success in formalising its methodology, defining its standards, and identifying its range of applicability. This symposium aims at furthering our understanding of the methodology by discussing four essential aspects: the underlying notion of causality, the role of theory, the problem of measurement in qualitative research, and the methodology's relationship with other forms of qualitative inquiry. It brings together methodological and substantive articles by young European scholars and summarises a round-table discussion with Peter A. Hall held at a workshop at the University of Oldenburg, Germany, in November 2010.

This article discusses the potential of case study and process-tracing methods for studying lobbying and framing in the European Union (EU). It argues that case studies and process tracing allow us to explore different sets of questions than large-N and quantitative approaches and to shed light on the mechanisms that contribute to policy change. Through these methods it is possible to study long-term processes and under-researched areas, to analyse the social construction of frames and to single out the conditions that lead to successful framing. In order to show the advantages of case studies and process tracing, illustrative examples drawn from the case study of EU foreign policy towards the Israeli–Palestinian conflict are provided.

This article recalls a distinction between research designs that focus on either the ‘causes of effects’ or the ‘effects of causes’ and compares it to a related but not identical distinction between the aims of developing and testing theoretical explanations. Using a study on environmental policy-making in the European Union as an example, the roles of process tracing and cross-case analysis in different combinations of these categories are highlighted.

The questions address the possibilities of a methodology to capture the temporal unfolding of events, which is an aspect difficult to model in statistical analysis but at the core of ambition of process tracing. Peter Hall is encouraged to present his view on the relevance of the study of causal mechanisms in the social sciences.

In recent years, Comparative Historical Analysis (CHA) has been developed as a methodological apparatus that is distinct from quantitative research in many respects. While this is correct, it is less apparent to what extent CHA is different from and adds something to the tools and techniques known from ordinary case study research (i.e., not tied to Historical Institutionalism). As a researcher who is attached to CHA, Peter Hall is invited to elaborate on this approach.

The questions address the ontological and epistemological implications of taking the ‘mechanismic’ view of causal mechanisms seriously, suggesting that they are more than events or series of intervening variables. Peter Hall is asked his views on the nature of causal mechanisms, and the logics of inference that we can use to study them in within-case analysis.

This article seeks to answer the question of how interbranch organisations (IBOs) can facilitate coordination among agents involved in transactions within agri-food chains. An IBO is a complex entity that establishes relationships among agents operating at different stages of a supply chain. The empirical analysis focuses on the Italian tomato supply chain and adopts a Process-tracing approach. The study is grounded in meso-institutions theory and demonstrates how the meso-institutional nature of the analysed IBO helps explain its role in establishing coordination among agents by performing the functions outlined by the theory. The institutional outcome of this relationship is the adoption of a contractual system that facilitates coordination itself. The contractual system identified provides an example of the articulation between the meso-institutional and micro-institutional levels.

Many studies have analysed what could motivate centre-right governments to develop progressive family policies, given their historically traditionalist ideology. Updating classic institutionalist accounts, this article expands the focus beyond centre-right parties formally in charge. It argues that in coalition and minority governments, partisan veto players may act as agenda-setters, design policy reforms and successfully exert pressure to approve them through three mechanisms: agreements for government formation, conditions for government survival and bureaucratic continuity. Drawing on novel empirical data from interviews and document analysis, this article applies deductive process tracing to analyse the German parental allowance reform of 2006 and the Spanish 2017 paternity leave extension. The findings complement existing studies that focus on the agency of centre-right parties as ‘protagonists’ of these reforms, arguing that in some cases they have instead ‘consented’ to reforms proposed and supported by other parties.

Co-management regimes are institutional innovations that hold the promise of achieving sustainable common-pool resource governance. However, the transition to such institutional regimes in coastal resource systems has faced challenges in many countries. This article examines the processes and outcomes of such institutional changes in coastal fisheries in Ghana, where the transition to co-management was unsuccessful. Combining theoretical perspectives from legal pluralism in legal anthropology and ideational theories of institutional change within institutional economics, the paper uses process tracing to examine the role of ideology and historical institutional dynamics of the resource context in the institutionalization and failure of co-management arrangements for governing coastal fisheries. The study finds that ideological conflicts and historical legacies of legal pluralism hindered the practice and outcomes of coastal fisheries co-management in Ghana. The article argues for particular attention to the historical institutional dimensions and underlying worldviews of the resource context in institutional interventions for sustainability in coastal resource systems.

The retrieval of past instances stored in memory can guide inferential choices and judgments. Yet, little process-level evidence exists that would allow a similar conclusion for preferential judgments. Recent research suggests that eye movements can trace information search in memory. During retrieval, people gaze at spatial locations associated with relevant information, even if the information is no longer present (the so-called ‘looking-at-nothing’ behavior). We examined eye movements based on the looking-at-nothing behavior to explore memory retrieval in inferential and preferential judgments. In Experiment 1, participants assessed their preference for smoothies with different ingredients, while the other half gauged another person’s preference. In Experiment 2, all participants made preferential judgments with or without instructions to respond as consistently as possible. People looked at exemplar locations in both inferential and preferential judgments, and both with and without consistency instructions. Eye movements to similar training exemplars predicted test judgments but not eye movements to dissimilar exemplars. These results suggest that people retrieve exemplar information in preferential judgments but that retrieval processes are not the sole determinant of judgments.
