Abstract
Behavior is a critical aspect of public budgeting research. However, much of the scholarly focus has been on collective budgeting behavior, leaving a gap in understanding individuals’ pre-negotiation judgment behavior. This oversight is concerning given evidence from adjacent fields that highlights predictable information-processing irrationalities due to human cognitive limitations. While it is plausible that cognitive biases also influence individuals’ judgments of budget proposals, behavior-informed insights from Economics, Psychology, and Public Administration have yet to be fully integrated into public budgeting research. In this article, we differentiate between individual budget judgment and collective budget negotiation, advocating for renewed attention to budgeting behavior at the micro-level. Through a scoping review, we gather empirically verified effects of cognitive biases on private financial decision behavior and discuss these findings within the context of public sector decision-making. Our theoretical contribution includes the development of an advanced behavioral model of Public Budgeting and hypotheses to test cognitive bias effects on individual budgeting action. Amid recent criticisms of behavioral public administration, we are developing research agenda aimed not only at testing the existence of bias but also at identifying solutions to change judgment behavior, thereby better equipping individuals for collective budgeting action.
Introduction
The government’s engagement with pressing public concerns, such as climate change, digitalization, migration, and inclusion, are increasingly pivotal (Moynihan, 2022). Despite the diverse nature of these concerns, they all necessitate resources, which are typically allocated by politicians (Sicilia & Steccolini, 2017). The behavior of these politicians during the budgetary process holds significant sway over final budget settlements (Rubin, 2020). Hence, it is unsurprising that extensive research spanning eight decades has delved into the behaviors of various budgeting actors.
Early scholars of budgeting sought to formulate normative theories to aid politicians in maximizing the utilization of public resources (e.g., Key, 1940), involving methodologies such as analyzing and comparing the marginal costs and returns of budget proposals (Lewis, 1952). However, the perception of budgeting as a political rather than purely economic process has redirected much of the focus in behavioral budgeting research toward individuals' behavior
Despite the wealth of insights derived from this research, we argue that there is a need for renewed focus to gain a deeper understanding of individuals’ behavior when they evaluate spending alternatives, prioritize savings opportunities, weigh priorities, and consider other factors
This study aims to broaden the understanding of budgeting behavior by proposing a multi-level model of public budget decision-making, where individual judgments are decoupled from collective negotiations. This allows for a deeper exploration of the formation of initial budget decisions—termed “predecisions”—which consistently serve as the foundation for collective action. Both judgment and negotiation involve distinct activities and behavioral patterns, which we will explore in greater detail below. The focus in this study is on the judgment phase, particularly the impact of cognitive biases on the formation of predecisions. Naturally, there will be variation in predecisions due to the diverse societal perspectives and political ideologies of politicians. However, this variability among individual politicians does not imply immunity from cognitive biases in micro-level budget decision-making. Below, we delineate the potential influence of bias on individual budgeting action and propose methods to investigate bias while recognizing the wide spectrum of individual preferences. Insight into these bias effects is crucial for enhancing budget judgment and better equipping individuals for negotiations.
The research question is:
We employ smart screening software to identify pertinent studies from a pool of 2,753 abstracts resulting from a scoping review of the literature. Each of the 44 selected studies provides empirical evidence on the impact of cognitive biases on the decision-making behavior of individuals in private sector, financial settings. The scoping review encompasses an array of distinct biases. This article examines the influence of the eight most extensively researched biases:
Toward a Behavioral Model of Budgeting Behavior
Budgeting behavior refers to the actions, decisions, and strategies employed by individuals or groups involved in the budgetary process. This encompasses various aspects, including how people assess information, negotiate settlements, and decide collectively about the use of public resources. In addition to fiscal and procedural autonomy, the behavior of politicians plays a significant role in determining the utilization of resources (Rubin, 2020). Given the critical role of politicians in making decisions, as well as the responsibilities of civil servants in preparing them, it is not surprising that scholars have dedicated considerable attention to studying their behavior.
Interestingly, a significant body of research highlights the behavior of individuals within the context of their interactions during the budgeting process. Insights gleaned from these studies delve deep into unraveling the dynamics of the “budgeting game”. They shed light on the reasons behind actors’ specific behaviors, such as systematically over-asking due to their awareness that others will push back on budget requests, unreasonably inflating certain events to persuade others to punctuate existing allocations or delaying decision-making to foster collective momentum (Jones & Baumgartner, 2009; Rubin, 2020; Wildavsky, 1988). Additionally, these studies demonstrate how individual conduct can be depoliticized by procedural interventions, such as establishing a fixed base and negotiating only on additional resources or minor adjustments (e.g., Lindblom, 1959; Schick, 2003). However, there has been relatively less emphasis on investigating the processes of individuals as they engage with budgetary information, leaving it unclear how individuals prepare for collective decision-making (see Litton, 2023). Do politicians possess the ability to logically process budgetary information, or do they, like decision-makers in other domains, face cognitive limitations that lead them to “overreact or underreact” to certain information features (cf. Cantarelli et al., 2023)? If so, this leads to biased predecisions that are less well-aligned with the objectives of politicians and complicate further negotiations.
To explore the cognitive aspects of politicians’ budgeting behavior, alongside their interpersonal interactions, we refine the behavioral model of the policy process created by Ewert et al. (2020) (refer to Figure 1). Our behavioral model of the budgetary process delineates actions and outcomes across micro-, meso-, and macro-levels, highlighting their interconnectedness. It implies that collective budget negotiations at the meso-level should be considered in relation to actions and outcomes at the other levels. This multi-level perspective is crucial because individual budgeting actions (i.e., judgments made by individuals on budget proposals) set the stage for collective action, directly influencing its course. Additionally, social changes at the macro-level resulting from negotiated expenditure, investment, and taxation decisions indirectly determine the conditions for both collective and individual behavior in the future.

Behavioral model of the budgetary process
Building on this model, we can explicitly focus on the micro-level where politicians, driven by their ambitions and ideologies, and process budgetary information to form preferences, or predecisions, for collective budget negotiations. These distinct levels of budgeting entail different activities and behavioral dynamics, adding complexity to budgeting decision-making. Addressing gaps in the literature, this study specifically examines the judgment behavior of individuals and the connection between individual and collective budgeting actions, highlighted by bolded boxes and arrows in the model.
To delve deeper into budget judgment behavior, we draw upon two bodies of knowledge. Research on microbudgeting provides one foundation (Thurmaier, 1995; Thurmaier & Willoughby, 2001). This literature underscores that individual budgeting action extends beyond mere economic-rational considerations of information. Instead, it involves multiple rationalities. Initially proposed by Key (1940), there exists an
Insights from behavioral studies in the fields of Economics, Psychology, and Public Administration, in particular, are instrumental in advancing this line of reasoning. A recent literature review on information use in public sector decision-making reveals that over 30% now adopt a behavioral lens, often focusing on cognitive biases and decision noise (Cantarelli et al., 2023). By integrating theories and methodologies from the behavioral science literature, new avenues emerge for comprehending and predicting individual’s budget judgment behavior. It is probable that budgeter’s preference formation is
Directly extrapolating insights from prior research to budget judgment behavior proves unfeasible. This limitation arises because much of the previous research in Economics and Psychology often neglects to differentiate between various types of information (cf. Head, 2016). Typically, the primary focus is on economic rationality and the logical processing of numerical information. However, considering that budget judgment encompasses multiple rationalities, thereby adding an extra dimension to information processing by individuals, it becomes imperative to explicitly explore the impact of cognitive biases on budget decision-making. In this article, we leverage existing literature to identify which biases have the most significant influence on financial decision-making in other domains. This process helps us formulate hypotheses for targeted research into the judgment behavior of individual politicians as they assess budget proposals and prepare for negotiations.
Methodology
We employ a two-step method to formulate a research agenda for Behavioral Public Budgeting. Initially, we utilize the relatively innovative approach of
Search Strategy and Study Selection
We utilized three search strategies to locate pertinent publications that explore the influence of bias on financial decision-making. We searched the Scopus database, focusing on the period post-2000, considering most empirical work would follow Barberis and Thaler’s (2003) seminal survey on Behavioral Finance. In October 2021, we executed a search to identify empirical publications on the behavioral dimensions of financial decision-making, utilizing the query

Utilizing Insights From the Review
Our scoping review reveals that 44 different biases have been investigated, with a significant portion of insights collected in Asian countries (73%), followed by Europe (15%) and the USA (4%). Behavioral research in financial decision making is contemporary, as most studies (84%) are published in 2018 or later. While the majority of these studies focus on investigating the effects of bias, a significant portion (41%) also delve into its antecedents. The predominant research approach is observational, with 71% of studies employing surveys to collect data. Eleven studies utilize interventional methods, including vignette and lab experiments.
A comprehensive list of biases is available on the journal website; however, we focus on the eight most prevalent ones in this article. This selection is primarily driven by numerical prevalence, with each of these biases examined in at least 10 separate empirical studies. It is important to acknowledge that alternate selections may have been made by other researchers. Furthermore, it is essential to note that the biases discussed herein are not exhaustive, and there exist additional cognitive fallacies that impact financial decision-making. Our decision to focus on these biases was made to allow detailed analysis, recognizing that certain biases, such as
This study centers on investigating the effects of
The most prevalent cognitive bias in our review is
In the realm of Public Administration, overconfidence remains relatively underexplored, despite its “undeniable importance warranting more focused research” (Battaglio et al., 2019, p. 314). Nonetheless, evidence suggests its relevance in public decision-making. For instance, Liu et al. (2017) demonstrate that overconfident bureaucrats, who overestimate their knowledge levels, consistently make poorer estimations. Similarly, Sheffer and Loewen (2019) find that overconfident politicians are more inclined to ignore information and take risks.
This suggests that overconfidence bias also distorts budget judgment behavior. When politicians overlook essential budget information features, their judgment is compromised. Overconfidence bias can lead politicians to be overly optimistic and develop predecisions with greater risk than they intend. Failure to utilize information may also result in implementation problems, especially when overly positive goals and estimates prove unattainable in practice. To investigate the influence of overconfidence bias, we posit the following hypothesis:
In Public Administration literature, herding bias relates to social norms, wherein scholars explore whether group behavior can influence individual behavior. Like herding, social norms tap into people’s reluctance to deviate from their groups. Research indicates, for instance, that health professionals are more likely to adopt a vaccine if they know their colleagues are doing so (Belle & Cantarelli, 2021). Moreover, field experimentation reveals that social norms play a significant role in citizens’ willingness to pay taxes compared to enforcement techniques (Larkin et al., 2018). Herding can yield either advantageous or disadvantageous outcomes. While peer preference information serves as a valuable tool for policymakers in guiding individuals toward desired courses of action, dependence on group behavior may lead them to disproportionately emphasize that information in their predecision making.
We hypothesize that herding bias influences budget judgment by causing politicians to assign disproportionate value to peer preference information. Politicians not only take deliberate actions to facilitate group decision-making but are also likely to be unconsciously influenced by their peers’ preferences. If politicians rely excessively on this information and ignore other inputs, they are more likely to formulate predecisions that do not effectively align with their personal goals. Instead of determining how to best achieve their own objectives by weighing various pieces of information, they primarily observe and follow the voting behavior of their colleagues. We propose the following hypothesis for empirical testing:
In Public Administration literature, representativeness bias has been a subject of study, with its impact varying across different contexts. Stolwijk and Vis (2021) demonstrate that politicians frequently make conjunction errors when estimating someone’s occupation and often overlook the broader scope when assessing earthquake probabilities. This observation aligns with the findings of Nielsen and Bækgaard (2015), who observed that politicians’ propensity to invest in a particular policy increases when recent performance in that policy area is strong. However, if they overreact to recent performance and neglect to consider the broader scope, there is a risk of overspending on approaches that have poor long-term performance.
We anticipate that representativeness influences judgment behavior, particularly through scope neglect. Similar to how financial decision-makers often base their forecasts of future profits on recent profit trends, we hypothesize that politicians tend to base their budget predecisions on overly narrow samples or limited past experiences. We expect that scope neglect will have a more pronounced effect on politicians’ behavior compared to experts. This expectation is grounded in microbudgeting research, which indicates that experts possess greater proficiency in evaluating and delineating the ramifications of budgetary decisions (Thurmaier, 1995). We propose the following hypothesis for empirical testing, which can be tailored to explore differences among various types of budgeting actors:
In Public Administration literature, the influence of anchoring is extensively documented and consistently supported (Battaglio et al., 2019). Studies indicate that managers exposed to high anchors tend to rate identical subordinates more favorably (Belle et al., 2017) and allocate employees more time to respond to emails (Belle et al., 2018). Anchoring also impact the preferences of politicians, leading them to accept higher taxes when primed with a high starting point, even when the possibility of tax abolition is emphasized (McCaffery & Baron, 2006).
Drawing from a wealth of empirical evidence, we anticipate that anchoring influences politicians’ judgment behavior, prompting their predecisions to gravitate toward the provided anchors. Despite anticipated diversity in individual preferences, it is likely that politicians unconsciously yet systematically align their decisions with anchor values. In budgeting contexts where numerical values play a crucial role, careful consideration of anchors, whether relevant or not, is essential. While anchors can sometimes aid decision-making, they may also distort judgment. This aligns with Sanders et al.’s (2018) suggestion that politicians are significantly swayed by the previous year's budget when tasked with applying a zero-based budgeting approach. To investigate the impact of anchoring bias, we propose the following hypothesis:
While the effect of high and low anchors has been extensively examined, there remains considerable uncertainty regarding the influence of anchors relative to the absence of anchors. LeBoeuf & Shafir (2006) observed that high anchors significantly impacted individuals’ estimates, whereas the low anchor and no anchor conditions yielded comparable results. We advocate for specific research aimed at investigating the effect of anchors in scenarios where no anchors are employed. The following hypotheses provide guidance for such inquiry:
In Public Administration literature, availability bias effects are also evident (Battaglio et al., 2019). When assessing public performance, people often overlook objective data and instead rely on easily recalled cues, such as recent events (Andersen & Hjortskov, 2016). Butler and Vis (2023) illustrate that topics receiving extensive news coverage disproportionately attract more attention from politicians. Sunstein and Zeckhauser (2011), on the other hand, find no impact of availability bias on people’s willingness to pay based on the perception of fearsome risks.
We posit that the influence of availability bias persists in budget judgment, particularly regarding spending on newsworthy items. It would be valuable to determine whether politicians overspend in such items compared to prevalent matters with lower news value. Drawing from insights across various decision domains, we hypothesize a correlation between the perceived newsworthiness of items and politicians’ propensity to allocate resources. This relationship can be examined through experimental manipulation of event characteristics. If, under otherwise identical circumstances, politicians demonstrate a higher willingness to allocate funds to “exceptional, well-publicized events” than to “prevalent, neglected events,” it suggests biased decision-making. In the discussion section, we will explore potential debiasing strategies. We expect that enhancing estimation quality could play a crucial role in reducing bias, prompting politicians to adjust their preferences based on objective assessments of event frequency. These propositions can be empirically tested using the following two hypotheses:
In Public Administration literature, loss aversion has garnered increasing attention. People may seek unreasonable reimbursements to offset losses (Battaglio et al., 2019), and managers’ overreaction to information about losses prompts unethical behavior (Belle & Cantarelli, 2017). Managers appear to take greater risks to compensate for losses (Deslatte et al., 2021). The relevance of loss aversion in budget decision-making is explicitly demonstrated by Litton (2023), who found that students and managers are more likely to choose risky options and are willing to spend more when a proposal is framed in terms of potential losses. Loss aversion is closely related to the
The insights derived from the review, supplemented by the findings of Litton (2023), lead us to believe that loss aversion bias also influences the formation of budget predecisions by politicians. In Litton’s study, both students and managers exhibited a preference for safer approaches when the budget proposal was framed in terms of gains. Therefore, we expect that also politicians exhibit a propensity to spend on safely framed approaches. The hypothesis can be articulated as follows:
On the contrary, when budget proposals in Litton’s (2023) experiment were framed in a loss-emphasizing manner, preferences shifted, with students and managers more frequently opting for the risky approach. To ascertain whether politicians exhibit a similar change in preference, and whether their willingness to spend consequently increases, we have formulated a second hypothesis regarding loss aversion:
Regret aversion remains relatively underexplored in Public Administration literature, yet it holds significant relevance for budgeting practices. It aligns closely with notions of incrementalism in microbudgeting, where politicians are hesitant to make sweeping, potentially riskier changes to existing allocations. Instead, they tend to favor incremental adjustments out of concern that disruptive changes could provoke political complications, impacting the balance of power. Insights from organization theory, such as Zeelenberg and Beattie’s (1997) research on the motivation to avoid regret, shed light on regret aversion beyond financial contexts. Individuals may adjust their risk-taking behavior based on past experiences and may deviate from rational decision-making principles when anticipating regret over potentially unjustified decisions. In such scenarios, individuals often opt to maintain the status quo or conform to prevailing preferences.
Building upon these insights, we propose that regret aversion affects budget judgment behavior. We argue that politicians’ preference for maintaining the status quo stems not only from a desire for political stability but also from their instinctive aversion to regret. Politicians intuitively anticipate the regret they may experience if disruptive changes to existing allocations do not yield favorable outcomes. Therefore, they tend to prefer the status quo or incremental changes that are easily reversible. The systematic consideration of regret may also deter politicians from initiating new projects or implementing new taxes, thereby contributing to a tendency toward inaction. To empirically investigate the impact of regret aversion, we propose the following hypothesis:
Despite its significance, mental accounting is understudied in Public Administration literature. To contextualize the insights from the review within the public sphere, we must draw upon the Public Finance literature. Here, it is revealed that citizens tend to assess the fairness of taxes by considering individual components rather than evaluating taxes as a whole (McCaffery & Baron, 2006). This behavior is associated with the
We anticipate that mental accounting also plays a role in shaping the formation of budget predecisions by politicians. Particularly in a context where a large budget is compartmentalized into increasingly smaller parts, the cognitive processing of these various labels will present a challenge. Despite the distinct legal status of actual budgetary accounts compared to mentally created accounts, it is evident that politicians become psychologically attached to designated accounts once they have been established. Politicians wield the authority to allocate the budget and create accounts, including the power to redirect funds from obsolete accounts. However, the termination of unused reserves or altering their designated purposes is not commonly practiced (Van der Lei, 2019). This reluctance to change may be linked to mental accounting bias that impedes the exploration of alternative expenditures, particularly when those expenditures are unrelated to the original earmark of a reserve. We formulate the following hypothesis to test the effect of mental accounting bias:
We consolidate the findings pertaining to common cognitive biases, alongside the formulation of 12 hypotheses, within Table 1.
Overview of Evidence and Hypotheses
Research Agenda
This study responds to recent calls for renewed attention to public budgeting behavior by leveraging insights from decision-making research in the private sector to refine and update existing perspectives in behavioral budgeting research. It acknowledges the complexities of comparing decision-making between the private and public domains, given the significant group dynamics involved in public budgeting compared to individual decision-making in the private sector. Also, while much of the reviewed literature focuses on investment decisions, this represents only one facet of public budget decision-making. Nevertheless, this perspective proves valuable in uncovering dynamics of financial decision-making behavior at the micro-level, particularly concerning the influence of cognitive biases. Rather than further refining concepts and effects through more precise and detailed reviews, we propose investigations to empirically explore the influence of biases and potential solutions. Below, we outline several research avenues aimed at validating and refining the theoretical foundations presented.
First, we advocate for targeted research to
Second, we emphasize the need for targeted research on
Finally, a significant criticism pertains to the focus of behavioral research on individuals, whereas decisions in the public sector are predominantly
Conclusion
This conceptual study draws on empirical evidence from adjacent academic fields to illustrate how cognitive biases distort politicians’ budget judgment behavior on the micro-level. While politicians’ preferences vary due to diverse societal, political and personal factors, their susceptibility to bias likely remains consistent. We propose twelve hypotheses and outline a research agenda to investigate whether biases lead to systematic and predictable judgment behavior. Although budget decisions ultimately involve group deliberations, the impact of biases on individual judgment behavior merits careful consideration. Systematic overreactions or underreactions to information features pose inherent risks and can significantly influence the collective allocation of public funds. Therefore, it is crucial to develop and test solutions aimed at mitigating these biases and correcting behavior. Doing so will facilitate negotiations with clearer starting positions, thereby enhancing the likelihood of securing adequate resources to effectively address public concerns that are deemed important by politicians themselves.
