ABSTRACT The Levin Center for Oversight and Democracy at Wayne State University Law School is in the process of creating the first‐ever comprehensive database of congressional oversight reports for all House and Senate Committees since the 106th Congress (1999–2000). In this article, we place these reports into the broader context of the tools Congress has to conduct oversight in service of its many legislative branch responsibilities under the Constitution. We also explain the development of the database. We conclude the article by discussing how the congressional scholars in this special issue use this database to examine how Congress conducts oversight, and we propose several additional areas for future study.
ABSTRACT How does unequal representation affect policymaking? Existing research shows that overrepresented districts exert disproportionate influence over public policy, yet our understanding of the underlying sources of this advantage remains limited. I argue that increased representation can independently bias policymaking via two channels: a mechanical effect, whereby additional representatives increase a district's likelihood of shaping the legislative agenda, and a behavioral effect, whereby legislators intensify constituency‐oriented effort due to intra‐district competition. To test this, I leverage the quasi‐experimental setting created by the electoral rule of the Italian Senate (1994–2006), which allowed districts with similar population sizes to elect either one or two senators. Using a regression discontinuity design and comprehensive data on bill (co‐)sponsorship, I find evidence consistent with both channels. Examining policy outcomes, I do not find that unequal representation yields distributive benefits, but I do find suggestive evidence of a broader legislative advantage.
ABSTRACT How do issue‐owning parties adapt their rhetoric when transitioning from opposition to government? Focusing on the Green parties in Germany and Ireland, we analyze legislative debates to trace how these parties seek to maintain ownership of environmental issues. Using more than 1.7 million parliamentary speeches from the German Bundestag (1991–2018) and the Irish Dáil (1992–2013), we apply a fictitious prediction problem approach implemented as a multiclass text‐classification task to measure distinctiveness in parties' legislative speeches. Our findings show that both parties increased their rhetorical distinctiveness on environmental issues during their first time in government, but with key differences: the Irish Greens maintained a distinct profile throughout their term, while the German Greens' distinctiveness increased as elections neared. No such patterns emerge for welfare, a non‐owned issue. Our study offers a framework and a transferable method for studying how smaller parties navigate between coalition influence and visibility through the issues they own.
ABSTRACT This article assesses the linkage between the House and Senate oversight committees' reports and subsequent legislative efforts in those policy areas from the 106th to the 116th Congresses (1999–2020). The analysis finds support for the three proffered hypotheses. First, the policy topics covered in the reports spur the referral of bills on those topics to the oversight committees. Second, the oversight reports on topics that the majority staff releases are more reflected in downstream legislative activity than the topics covered in the minority staff reports. Finally, the majority's advantage in pushing legislation related to its oversight reports' topics is greater in the House than it is in the Senate. These initial findings substantiate the importance of gathering and coding congressional oversight reports for not only how Congress conducts oversight, but also how it legislates.
ABSTRACT This study investigates the effect of committee leadership positions on political fundraising in the South Korean National Assembly from 2004 to 2019. Drawing upon theories of legislative power and campaign finance, we examine whether acquiring standing committee chairmanships significantly increases political contributions received by legislators, even within Korea's highly restrictive regulatory regime that prohibits corporate donations. Utilizing OLS regression and difference‐in‐differences with Panel Matching methodology, we find compelling evidence of a substantial leadership premium. OLS estimates reveal that committee chairs consistently outraise non‐chairs by 16%–21%; Panel Matching estimates confirm an immediate increase of approximately 1.15 log‐points (a 216% increase) following chair appointment. Event study analysis validates our identification strategy by demonstrating parallel pre‐trends and sharp treatment effects at the moment of leadership transition, with effects dissipating after chairs leave their positions. Split‐sample OLS estimates reveal a cross‐over pattern: the premium is significant for Targeted and Mixed committees in the first half of the legislative term but shifts to Universal committees in the second half, suggesting that the relevant dimension of heterogeneity may be whether a committee holds jurisdictional authority over concentrated regulatory or budgetary stakes. These findings demonstrate that the link between institutional power and political money persists even under highly restrictive campaign finance regimes—reflecting structural features of legislative organization that transcend specific regulatory designs. The individual‐as‐proxy mechanism we identify, whereby organized interest groups circumvent the corporate donation ban through coordinated individual‐level contributions, suggests that regulation reshapes the channels of strategic giving without eliminating its underlying demand.
What inspires and propels investigative work in Congress? Members consistently cite legislative action to claim credit for their investigations, but what makes certain inquiries more legislatively productive than others? In this paper, I link members' investigative and legislative work and argue that committee investigations represent a crucial stage in the broader policymaking process in Congress. I assess the structure of House Oversight Committee investigations and the role of each component part in predicting legislative outcomes. I show that, contrary to their reputation as theatrical time-wasters, public nonlegislative committee hearings contribute to problem-solving via both individual and collective legislative action. Additionally, I offer a normative upside to the effects of partisanship on executive-targeted investigations: Committee investigations are more legislatively productive under divided rather than unified government.
Prominent theories of campaign issue strategy provide three main perspectives candidates can adopt when deciding what issues to discuss: (1) issues voters view their party as "owning", (2) "trespassing" onto issues that the other party owns, and (3) addressing timely and salient issues (e.g., "wave riding"). This paper examines candidate issue messaging strategies in congressional primary campaigns. By isolating party-owned issues and issue trespassing from wave riding, a distinction not typically made in previous literature, we explore how candidate characteristics and electoral conditions influence the use of these three strategies in primary elections. Leveraging a dataset of campaign website issue platforms for nearly all congressional candidates running in primary elections from 2018 to 2022, we find that incumbent candidates dedicate relatively more of their campaign platform to party-owned and opposing party-owned issues compared to challengers. Further, we find that candidates who must appeal to a partisan primary electorate spend relatively less time engaging in issue trespassing, but discuss salient, wave riding issues more. Overall, our results contribute to the growing body of literature on issue messaging strategies and primary elections.
Congress negotiates while uncertain about the effects of proposed policies, and often relies on committees to conduct oversight that reports about the past and projects the future. Little is known about their conclusions, their accuracy, and how politics seeps into what they choose to report. We apply a typology of knowledge claims contained in congressional oversight, which classifies them based on whether they are prospective or retrospective, and whether they contain an inference. We use a large language model (LLM) to extract findings, evaluations, predictions, and recommendations from a new dataset of committee reports issued in the 103rd-118th Congresses. We argue that partisan investigation teams reveal more raw findings and make fewer recommendations, relative to bipartisan teams, which is consistent with their need to demonstrate they have acquired expertise. Our study pilots a general approach to studying the acquisition and sharing of information in legislative oversight.
State legislators play a key role in election administration, but have increasingly challenged the legitimacy of elections. Using a dataset of tweets from over 4200 state legislators, we examine the institutional, individual, and state-level factors associated with legislators' propensity to make electoral fraud claims from 2019 to 2022, a period characterized by heightened criticism of status quo electoral procedure. We find that Republican partisanship, state polarization, serving in a state with a higher nonwhite population, and belonging to the state's upper chamber are correlated with more frequent election fraud tweets. Meanwhile, legislative professionalism, committee leadership, unified government, and being a female legislator are associated with making fewer fraud claims. By shifting attention from Congress to state legislatures-institutions that directly oversee election rules and administration-we identify correlates of public contestation of electoral procedure among subnational elites.
Do part-time politicians benefit professionally from holding political office? Despite the prevalence of part-time officeholders in democratic systems, little is known about how political service interacts with ordinary careers. This study examines whether entering part-time local office affects politicians' likelihood of attaining managerial positions in their non-political employment. Leveraging Danish electoral data from 1997 to 2013 linked to administrative labor-market registers, I employ an event-study design comparing narrowly elected winners and losers in municipal elections. The analysis distinguishes effects across public versus private employment and jobs inside versus outside the municipality. The results show that winning office increases the probability of holding a public-sector managerial position within the municipality by about one percentage point-substantial relative to a low baseline-while no effects emerge elsewhere. Electoral victory also increases candidates' likelihood of pursuing and attaining local and national political office. These findings indicate modest but meaningful career rewards concentrated where political authority is exercised.
How legislators divide their efforts between constituency service and parliamentary work has long attracted scholarly attention, yet we know far less about how voters evaluate this trade-off. This paper addresses this gap by examining how voters evaluate legislators' effort allocation between constituency service and parliamentary work in Taiwan, a context where legislators traditionally devote substantial energy to constituency service, and how pre-existing representational priorities condition these evaluations. We employ an original conjoint experiment and show that Taiwanese voters generally prefer legislators who balance constituency service and parliamentary work, while penalizing those who focus too heavily on one dimension. Furthermore, we demonstrate that citizens' stated representational priorities shape these evaluations: respondents who prioritize parliamentary work favor legislators who allocate more effort to national policymaking, whereas those who prioritize constituency service reward greater local engagement. Taken together, these findings suggest that a preference for balanced representation may be widespread and that incorporating voters' expectations is essential for understanding the dynamics of political representation.
This study examines legislative gatekeeping in the South Korean National Assembly by analyzing bill review subcommittee meeting frequency from 2004-2024. Unlike the U.S. Congress, where majority parties monopolize committee chairs, Korea's proportional chair allocation system creates a unique institutional setting for testing party cartel theory. Using negative binomial regression on 3314 committee-months, we find that partisan coordination between committee and subcommittee chairs significantly increases meeting frequency, whereas ideological extremism reduces legislative activity. Meeting patterns follow an inverted U-shaped electoral cycle, peaking during midterm periods. These effects vary systematically across committee types, with mixed committees showing different dynamics than particularistic or universal goods committees. The findings extend party cartel theory beyond majoritarian systems, demonstrating how "negotiated procedural control" operates when institutional power is distributed rather than monopolized.
Why do senators choose to talk about filibustering, a tool widely associated with obstruction and gridlock? This paper examines how senators strategically reference filibustering in official communications, focusing on two rhetorical frames: credit claiming and blaming. Using an original dataset of Senate press releases from the 109th through 118th Congresses, I show that filibuster rhetoric is structured primarily by party status: minority-party senators claim credit for obstruction, while majority-party senators assign blame. Individual-level factors such as electoral safety and ideological extremity play a limited role. Contrary to expectations, filibuster credit claiming has declined over time, while evidence of increased blaming is mixed. Additional analyses show that these patterns persist across institutional contexts, including unified and divided government, respond to changes in filibuster rules for judicial nominations, and shift within senators as party control changes. Filibuster rhetoric serves as a strategic tool for signaling resistance and shifting blame.
I examine the extent to which interest groups attend to institutional rules and procedures of lawmaking by assessing how they reward legislators who hold different forms of procedural authority in U.S. state legislatures. Revisiting an influential attempt to gauge interest group interest in procedural power, I reassess how "committee assignment power" has been measured and interpreted and ask what donors reward when they give to legislators coded as holding appointment authority. The analysis focuses on contributions directed toward actors involved in committee organization rather than direct access to committee members. I show that the contribution premium associated with assignment authority is composition sensitive and concentrated in a subset of chambers and leadership positions rather than uniformly observed across legislatures. Because offices involved in committee organization frequently bundle multiple procedural capacities, estimated assignment effects are difficult to attribute to appointment authority alone. The results suggest that donors reward bundled leadership capacities that structure the legislative agenda rather than committee appointment authority in isolation. More broadly, commonly used institutional measures may collapse multiple levers of power into a single indicator, and campaign finance may reinforce procedural centralization within legislatures as well as shape policy outcomes.
The minority party in Congress faces structural barriers to influencing policy and controlling the oversight agenda. Yet even when excluded, it can use investigations and formal reports to challenge majority narratives and sustain political visibility. Building on foundational theories of legislative behavior, oversight, and recent work on minority party strategy, we examine when and how the minority uses formal oversight reports and differentiate their behavior from the majority. Using data from the Congressional Oversight Records Database (CORD), we find that minority-issued reports become shorter under unified government, less frequent when the minority is rolled more often on the floor, and longer when the minority has recently lost majority control or when its members have greater committee experience. These findings show that minority oversight is both constrained and strategic; it expands in depth when experience and recent displacement provide motivation but contracts in scope when institutional exclusion is greatest. These findings contribute to emerging research built around CORD by showing that oversight serves as a durable yet limited outlet for the minority party seeking to challenge or advance their own narratives.
This article examines parliamentary speech as a job-market signal in Westminster systems, where ministers are selected from the legislature under conditions of informational asymmetry. Building on signaling theory, it argues that party leaders use visible, effortful parliamentary activities-such as frequent speechmaking-as proxies for latent qualities like political aptitude and commitment. Using data from Australia, Canada, Ireland, and the UK, it finds that a one standard deviation increase in first-term speech rate is associated with a 27% [95% CI: 19, 36] increase in the risk of ministerial promotion. The relationship is role-specific (predicting ministerial but not whip appointments) and robust to confounds such as elite education, gender, and prior experience. These findings contribute to the literatures on ministerial selection and parliamentary debate by reframing parliamentary speech as a strategic investment. They also challenge critical conceptions of the Westminster model by showing how fused executive-legislative dynamics shape ministers' career incentives and understanding of institutional design.
In the US Congress, rising partisanship in foreign policymaking has heightened pressure on co-partisans to defer to the president. Simultaneously, post-Cold War expectations for congressional engagement have pushed legislators to be more active in foreign affairs. How do co-partisan members balance these conflicting demands? This paper argues that co-partisan legislators navigate these competing pressures through selective activism, rather than simply delegating foreign-policy authority to the executive. Analyzing the cosponsorship of foreign policy bills, the study demonstrates that co-partisans maintain engagement by promoting policies aligned with their president while strategically avoiding those that conflict with the administration's agenda. Furthermore, the analysis shows that cosponsorship significantly increases the likelihood of final passage, indicating that selective activism carries substantive policy consequences. By illuminating the nuances of co-partisan engagement, this study broadens our understanding of how partisanship and activism interact to shape congressional behavior in a domain traditionally dominated by the president.
Measuring the value of cabinet portfolios is a fundamental task in the study of coalition politics. Yet existing measures are often static, have limited coverage, or assume that all parties value portfolios equally. In this paper, we introduce a new approach that overcomes these problems. We argue that parties signal their portfolio preferences through legislative behaviors, such as floor speeches, bill sponsorship, motions, and budgetary earmarks. Leveraging these behaviors as inputs, we develop and validate a dynamic Bayesian latent-variable model to disentangle two concepts: a portfolio's underlying salience and the specific value each party assigns to it, independent of the effects of office-holding. Applying this method to Brazil, a presidential system in which government coalitions and cabinet changes are frequent, we show that our estimates capture portfolio importance and their temporal shifts better than alternative measures. Furthermore, we show that portfolio allocation among coalition parties is more proportional once we weight portfolios using our salience scores. We provide a checklist and a replication repository applied to Denmark for researchers interested in adapting our framework to other contexts.
This article introduces the concept of priority responsiveness, which assesses the extent to which representatives' issue priorities reflect those of male and female citizens equally. Arguing that political priorities are a crucial but overlooked dimension of responsiveness, I analyze 131,601 survey responses on citizens' most important problems and 127,830 parliamentary speeches and identify a gap in priority responsiveness in the gender-egalitarian context of Norway. Representatives focus more on issues prioritized by male citizens than by female citizens. This disparity appears to be driven by representatives' tendency to emphasize issues prioritized by citizens of their own gender. Since women deliver fewer speeches than their male counterparts, their stronger emphasis on issues prioritized by women does not substantially affect overall responsiveness. By contrast, male representatives' greater focus on issues important to men appears to drive the bias. Neither party affiliation nor government ideology significantly affects the gender bias in priority responsiveness.
Polls show that men are less likely to support gun restrictions than women, but do voter preferences translate into elite behavior? To answer this question, we use a novel dataset of hand-coded state firearm legislation across six politically diverse states (California, Florida, Iowa, Illinois, Michigan, Texas) to construct an 11-year panel dataset. Our results demonstrate that descriptively, women generally cosponsor more restrictive and fewer permissive gun policy bills than men, even after accounting for partisanship. Using multiple staggered difference-in-differences specifications, we find women are no more likely than men to advance restrictive gun bills, yet they do cosponsor fewer efforts to expand gun rights (permissive bills). Our findings imply that electing more women may not substantially increase efforts to tighten gun laws but could curb gun rights expansion, showcasing how gender may shape legislation through agenda restraint rather than by promoting active policymaking.
