Bureaucrats, interest groups and policymaking: a comprehensive overview from the turn of the century

The study investigates how bureaucrats (non-elected government officers) interact with interest groups in policymaking, addressing a comparatively underexplored nexus in political science. While extensive research examines bureaucrats’ ties to politicians, parties, and ministers, fewer studies analyze their connections to interest organizations. The paper aims to advance this agenda by mapping and synthesizing recent literature across public administration and lobbying/interest-group studies to identify topics, gaps, methods, and theoretical approaches. Three research questions guide the analysis: (i) How does recent research approach interactions between bureaucrats and interest groups? (ii) What methods and strategies predominate? (iii) What does empirical evidence reveal about how interest groups interact with the public bureaucracy? Initial bibliometric evidence suggests a larger body of work than expected, but concentrated on specific themes (venue choice, influence on policymaking) and dominated by US and European scholarship. The paper positions its contribution as an integrative literature review combining bibliometrics and qualitative content analysis to clarify concepts, synthesize findings, and highlight future directions, with datasets made available in an open repository.

The paper reviews research from 2000–2022 at the intersection of bureaucracies and interest groups. It notes the lack of a consensual definition of “interest groups,” variation in whether NGOs are included, and frequent conflation with lobbying. Coding of stakeholders referenced as interest groups most commonly identified firms/trade associations/business groups, citizens/public-interest groups, and unions/professional associations. Bibliometric network maps (VOSviewer) show that “bureaucracy” and “lobbying/interest groups” largely form distinct clusters with some connections; corruption and public policy link the clusters, while political appointments cluster with patronage, clientelism, and parties rather than interest groups. Titles/abstracts analysis similarly shows bureaucracy linked to government, politicization, appointments, and corruption, while interest groups are linked to policy and influence; “government official” often refers to both elected and non-elected officials. The qualitative review of 415 texts finds: (1) frequent mention of corruption; (2) lobbying studies center on interest group influence over policymaking and increasingly mention bureaucrats; (3) bureaucratic politicization studies rarely mention interest groups, focusing instead on bureaucrat–politician relations. Main thematic strands include access and venue choice (interest groups’ decisions to lobby agencies vs legislatures), influence on bureaucratic rulemaking, and revolving doors. Far fewer studies examine interest groups’ direct influence on political appointments or bureaucrats’ memberships and personal networks. The literature on bureaucratic profiles (e.g., representative bureaucracy, bureaucratic activism) often omits nonpartisan organizational ties. The appointments literature tends to emphasize presidential/party control and delegation dynamics (especially in the US), with limited empirical work on direct IG influence over selections. Research is regionally concentrated in the US and Europe, and theoretical frameworks often reflect US institutional features, limiting generalizability. Informal institutions (patron–client relations) are largely neglected despite their potential relevance in shaping bureaucrat–IG interactions.

An integrative literature review combined bibliometric analysis and qualitative content analysis. Data sources: Scopus and Web of Science. Search terms (2000–2022) combined bureaucracy/bureaucrat/civil servants/government officers/officials with (i) interest groups/lobbying/advocacy/pressure groups/interest organisations/lobbyists; (ii) politicisation; (iii) patronage. Initial data were exported to separate folders and merged in Mendeley, with exclusions for non-academic materials and off-topic uses (e.g., private-sector ‘bureaucracy’, ‘patronage’ in arts, incidental mentions). The general collection included 1,978 items (articles, books, reports, chapters). Tools: VOSviewer and R Studio for bibliometrics; all 1,978 abstracts were read. Screening for qualitative analysis applied criteria: contemporary period; policy cycle phases of policymaking/rulemaking/appointments (excluding evaluation); executive branch/federal agencies/committees (excluding SOEs and courts); journal articles/chapters; focus on senior officers. This yielded 484 texts; after removing reports/books/unavailable items and adding some relevant citations, and accounting for language availability, the final coded sample was 415 journal articles/chapters/papers (mostly in English, some in French, Spanish, Portuguese; abstracts in English were analyzed for other languages). Coding in NVivo followed a deductive approach based on prior theory and initial abstracts, with iterative refinement; codes covered actor interactions, countries, methods, and theoretical frameworks. Limitations included breadth of phenomenon and terminology, potential selection bias, incomplete metadata, and language constraints; mitigations included large sample sizes (N=1,978 and N=415) and reading all abstracts. Network maps used occurrence/co-occurrence thresholds and a thesaurus to merge similar terms.

• Thematic concentration: Most publications focus on interest group strategies, venue choice (legislative vs administrative venues), revolving doors, and influence over policymaking/rulemaking. Far fewer examine direct interest group influence over political appointments and the personal networks/memberships of bureaucrats.
• Clustering: Bibliometric maps show bureaucracy, political appointments, and interest groups as separate clusters linked via corruption and public policy. Appointments cluster more with patronage, clientelism, and parties than with interest groups.
• Access as proxy for influence: Access to bureaucracy is often used as a proxy for influence, but causal mechanisms for why bureaucrats comply with IG preferences remain underexplored.
• Sparse evidence on appointments: Quantitative content indicates 82 documents link appointments to parties, 82 to presidents, but only 16 link appointments to interest groups, underscoring a gap in direct IG influence on selection of bureaucrats.
• Revolving doors: Studies document movements between public and private sectors (including EU cases), but this literature is somewhat siloed from broader public administration research.
• Methods: Regression is the predominant method (155 documents), followed by surveys (89) and in-depth interviews (82), helping identify patterns but offering limited insight into causal mechanisms.
• Theory: Principal–agent/delegation frameworks are most common (54 documents), complemented by rational choice/formal models (32). Institutional analyses emphasize formal institutions (regimes n=41; systems of government n=35), with limited attention to informal institutions (n=4).
• Geography and authorship: Scholarship is concentrated in the United States and Europe; authors with ≥3 publications are mostly affiliated with US, UK, or European institutions. The US, UK, and EU are the most-cited contexts, suggesting a global North bias and potential limits to theory travel.
• Stakeholder composition: Business groups/firms/trade associations are the most frequently referenced interest groups, followed by public interest groups and unions/professional associations.

Findings address the research questions by showing that interactions between interest groups and bureaucrats are indeed studied but primarily through the lenses of access, venue choice, and rulemaking influence. This reveals a literature that is rich in documenting contacts and outcomes but thin on explicating causal mechanisms—why bureaucrats accede to interest group preferences, and through which pathways. The dominance of principal–agent frameworks, quantitative methods, and US/European cases helps explain emphases on formal oversight, delegation, and legislative–executive dynamics while leaving informal institutions and non-Western contexts underexplored. The sparse empirical work on direct IG influence over appointments and limited attention to bureaucrats’ memberships/personal networks suggest that significant aspects of political connections remain overlooked. Integrating public administration and lobbying literatures, expanding methodological toolkits (triangulation, network analysis, process tracing), and incorporating informal institutions can better capture the multi-tier interactions among politicians/parties, bureaucrats, and interest groups across diverse institutional settings. Broadening regional and linguistic coverage is critical for developing theories that travel beyond the US–Europe axis.

The review demonstrates a substantial but segmented literature: interest group studies emphasize strategies, access, and rulemaking influence, while bureaucracy research focuses on politicization and party/presidential control. Two central gaps are identified: (i) limited empirical evidence on interest group influence over political appointments; and (ii) scant attention to bureaucrats’ political engagement and memberships beyond parties. Addressing these requires closer integration of public administration and lobbying research, greater consideration of informal institutions (e.g., patron–client relations), and methodological triangulation to uncover causal mechanisms. Regional diversification beyond the global North is needed to develop concepts and theories that travel effectively. The author outlines next steps to conduct additional reviews in French, Spanish, and Portuguese and a qualitative comparative study to build and test theories beyond traditional approaches.

• Conceptual/terminological breadth complicates search and identification; key terms (e.g., lobbying, interest groups) carry stigma and are used inconsistently across studies.
• Potential selection bias due to availability and researcher screening decisions; some items lacked metadata (keywords/abstracts), hindering bibliometric analysis.
• Language constraints: focus on English in Scopus/Web of Science; some non-English texts included but others excluded; results may reflect an English-language and global North bias.
• Scope limitations: excluded evaluation phase, state-owned enterprises, courts, and focused on senior officials; findings may not generalize across all policy cycle phases or institutional arenas.
• Predominance of quantitative methods in the literature limits insight into causal mechanisms, underscoring the need for mixed methods and qualitative depth.
