The Financial Knowledge Scale: An Application of Item Response Theory to the Assessment of Financial Literacy

Financial Literacy, Financial Education, and Downstream Financial Behaviors

Policy makers have embraced financial education as a necessary antidote to the increasing complexity of consumers' financial decisions over the last generation. We conduct a meta-analysis of the relationship of financial literacy and of financial education to financial behaviors in 168 papers covering 201 prior studies. We find that interventions to improve financial literacy explain only 0.1% of the variance in financial behaviors studied, with weaker effects in low-income samples. Like other education, financial education decays over time; even large interventions with many hours of instruction have negligible effects on behavior 20 months or more from the time of intervention. Correlational studies that measure financial literacy find stronger associations with financial behaviors. We conduct three empirical studies, and we find that the partial effects of financial literacy diminish dramatically when one controls for psychological traits that have been omitted in prior research or when one uses an instrument for financial literacy to control for omitted variables. Financial education as studied to date has serious limitations that have been masked by the apparently larger effects in correlational studies. We envisage a reduced role for financial education that is not elaborated or acted upon soon afterward. We suggest a real but narrower role for “just-in-time” financial education tied to specific behaviors it intends to help. We conclude with a discussion of the characteristics of behaviors that might affect the policy maker's mix of financial education, choice architecture, and regulation as tools to help consumer financial behavior.

The ABCs of Financial Education: Experimental Evidence on Attitudes, Behavior, and Cognitive Biases

This paper uses a large-scale field experiment in India to study attitudinal, behavioral, and cognitive constraints that can stymie the link between financial education and financial outcomes. The study complements financial education with (i) financial incentives on a financial literacy test to affect participant motivation, (ii) financial goal setting to provide a psychological nudge, and (iii) personalized financial counseling to enhance the intensity of treatment. The analysis finds no impact of financial incentives on learning but significant effects of both goal setting and counseling on real financial outcomes. These results identify important complements to financial education that can bridge the gap between financial knowledge and behavior change.

Debt literacy, financial experiences, and overindebtedness

We analyze a national sample of Americans with respect to their debt literacy, financial experiences, and their judgments about the extent of their indebtedness. Debt literacy is a component of broader financial understanding that measures knowledge about debt and self-assessed financial knowledge. Financial experiences are the participants’ reported experiences with traditional borrowing, alternative borrowing, and investing. Overindebtedness is a self-reported measure. Debt literacy is low, with only about one-third of the population grasping the basics of interest compounding. Even after controlling for demographics, we find a relationship between debt literacy and both financial experiences and debt loads. Individuals with lower levels of debt literacy tend to transact in high-cost manners, incurring higher fees and using high-cost borrowing. We provide a rough estimate of the national implications of debt ignorance on credit card costs by consumers. Less knowledgeable individuals also report that their debt loads are excessive or that they are unable to judge their debt position.

5: Behavioural biases in personal finance

Behavioural economics merges psychology and economics to explore systematic deviations in financial decision-making from traditional economic models. This chapter examines key biases such as mental accounting, present bias, planning fallacy, and misunderstanding of risk, which influence spending, saving, investing, and insuring decisions. Demonstrating the interplay of cognitive biases and heuristics highlights why individuals make suboptimal choices despite financial literacy and resource capacity. Strategies like goal-setting, commitment devices, and education interventions are evaluated, focusing on their limitations and potential for addressing these biases. The chapter concludes by emphasising the need for systemic changes, such as policy-level interventions and financial regulation, to complement behavioural interventions and address structural barriers to better financial decisions. Future research directions are suggested, including tailoring interventions, exploring technology's role, and integrating systemic solutions to support sustainable financial well-being.

Financial product sensitivity predicts financial health

Abstract Recent research has aimed to understand how people consider financial decisions because they have important consequences for well‐being. Yet existing research has largely failed to examine how attitudes and behaviors vary as a function of the specific financial product (e.g., debt type). We ask to what extent people differentiate between similarly categorized financial products (e.g., debt or investment) as a function of their terms (e.g., interest costs and expected returns) and whether such differentiation predicts financial health. Across four studies, we find not only that there are individual differences in attitudes toward similar financial products (e.g., two distinct loans), but also that the extent to which a consumer is averse to high‐cost versus low‐cost products predicts financial health. This relationship cannot be fully explained by financial literacy, numeracy, or intertemporal discounting. In addition, nudging people toward differentiating between financial products promotes decisions that are aligned with financial health.

Artificial intelligence and personal finance

Artificial intelligence (AI) is transforming how consumers access and use financial information, education and advice for personal financial decision making. While consumers’ increasing use of AI tools and AI-generated content for personal finance brings opportunities in terms of accessibility, personalisation and decision making, it also increases risks related to bias, hallucinations, commercial influence, data privacy and exclusion, with uncertain benefits on long-term financial well-being. This policy paper provides policymakers and stakeholders with an overview of current trends, opportunities and risks in the use of AI in personal finance and in the design and delivery of financial education. It also proposes a set of financial literacy competencies to support the use of AI in personal financial decision making.

Household Finance

Household financial decisions are complex, interdependent, and heterogeneous, and central to the functioning of the financial system. We present an overview of the rapidly expanding literature on household finance (with some important exceptions) and suggest directions for future research. We begin with the theory and empirics of asset market participation and asset allocation over the life cycle. We then discuss household choices in insurance markets, trading behavior, decisions on retirement saving, and financial choices by retirees. We survey research on liabilities, including mortgage choice, refinancing, and default, and household behavior in unsecured credit markets, including credit cards and payday lending. We then connect the household to its social environment, including peer effects, cultural and hereditary factors, intra-household financial decision-making, financial literacy, cognition, and educational interventions. We also discuss literature on the provision and consumption of financial advice.

The Credit Card Debt Puzzle: The Role of Preferences, Credit Access Risk, and Financial Literacy

Abstract. We use the 1979 National Longitudinal Survey of Youth to revisit what is termed the credit card debt puzzle: why consumers simultaneously co-hold high-interest credit card debt and low-interest assets that could be used to pay down this debt. Relative to individuals with no credit card debt but positive liquid assets, borrower-savers have very different perceptions of future credit access risk and use credit cards for precautionary motives. Moreover, changing perceptions about credit access risk are essential for predicting transitions among the two groups. Preferences and the composition of financial portfolios also play a role in these transitions.

Behaviorally Informed Policies for Household Financial Decisionmaking

Low incomes, limited financial literacy, fraud, and deception are just a few of the many intractable economic and social factors that contribute to the financial difficulties that households face today. Addressing these issues directly is difficult and costly. But poor financial outcomes also result from systematic psychological tendencies, including imperfect optimization, biased judgments and preferences, and susceptibility to influence by the actions and opinions of others. Some of these psychological tendencies and the problems they cause may be countered by policies and interventions that are both low cost and scalable. We detail the ways that these behavioral factors contribute to consumers’ fiancial mistakes and suggest a set of interventions that the federal government, in its dual roles as regulator and employer, could feasibly test or implement to improve household financial outcomes in a variety of domains: retirement, short-term savings, debt management, the take-up of government benefits, and tax optimization.

Do people like financial nudges?

Do people like financial nudges? To answer that question we conducted a pre-registered survey presenting people with 36 hypothetical scenarios describing financial interventions. We varied levels of transparency (i.e., explaining how the interventions worked), framing (interventions framed in terms of spending, or saving), and ‘System’ (interventions could target either System 1 or System 2). Participants were a random sample of 2,100 people drawn from a representative Australian population. All financial interventions were tested across six dependent variables: approval, benefit, ethics, manipulation, the likelihood of use, as well as the likelihood of use if the intervention were to be proposed by a bank. Results indicate that people generally approve of financial interventions, rating them as neutral to positive across all dependent variables (except for manipulation, which was reverse coded). We find effects of framing and System. People have strong and significant preferences for System 2 interventions, and interventions framed in terms of savings. Transparency was not found to have a significant impact on how people rate financial interventions. Financial interventions continue to be rated positive, regardless of the messenger. Looking at demographics, we find that participants who were female, younger, living in metro areas and earning higher incomes were most likely to favor financial interventions, and this effect is especially strong for those aged under 45. We discuss the implications for these results as applied to the financial sector.

The Ostrich in Us: Selective Attention to Personal Finances

Abstract We analyze attention to personal finances using a high-frequency panel of bank data, including information on logins. We document a number of robust patterns. Relative to their personal histories, individuals pay more attention when holding more cash and liquidity and when receiving income. In contrast, attention decreases discretely as bank account balances go from positive to negative and then decreases further as overdraft debt increases. We conclude that Ostrich effects in a personal finance context, i.e., the avoidance of obtaining information on everyday personal finances, is a widespread phenomenon and explore a number of explanations for our findings.

Perspectives on mental accounting: An exploration of budgeting and investing

This article provides an overview of recent advances in the literature on mental accounting within the context of consumer financial decision‐making. We first discuss the categorization process that underlies mental accounting and the methods people use to categorize funds. We then highlight some of the notable work that examines how mental accounting influences budgeting, spending, and investment decisions. The article concludes by proposing an agenda for future research, focusing on current gaps in our knowledge and promising areas to explore.

Savers and Borrowers: Strategies of Personal Financial Management

Saving and borrowing are traditionally and stereotypically thought of as opposites, with different motivations and consequences. Through a questionnaire survey of economic position, practices, and attitudes, the present paper examined the relation between saving and borrowing among British respondents. While saving and borrowing were found to be determined by different economic, social, and psychological factors, they did not describe mutually exclusive strategies of financial management. Saving regularly could also be distinguished from having savings. In all, six strategies were identified (combining saving or not saving, borrowing or not borrowing, and having or not having savings). Each combination was found to have specific discriminating characteristics. Savers and borrowers were found to have different psychological motivations, seeing debt either as a failure or as a normal part of everyday life. Many people retained savings or carried on saving at the same time as having debts: they were found to feel more in control and optimistic about their financial position than those who had debts but no savings. A further group had neither debts nor savings: they adopted an inflexible approach to financial management. Each group of people with different financial management strategies was illustrated by a case study.

Beyond Income: Dynamic Consumer Financial Vulnerability

This research challenges the entrenched belief that financial vulnerability affects only low-income consumers. Instead, most consumers across the socioeconomic spectrum experience varying degrees of financial vulnerability at different points during their lives, whether sporadically or chronically; vulnerability is dynamic and heterogeneous. The authors propose a novel, theory-driven definition of consumer financial vulnerability (CFV) as the risk of incurring future harm, given the consumer's current access to various financial resources. A new conceptual framework decouples “vulnerability” from “harm” to distinguish the state of CFV, its determinants (access to various interdependent financial resources), and the constructs it foreshadows (multiple interconnected forms of realized harm). Five research propositions follow: (1) financial resource volatility plays a vital role in CFV, (2) recovering from harm requires more financial resources than preventing harm, (3) a multiperiod lens is needed to assess CFV accurately, (4) greater financial resource access can increase CFV, and (5) generalized financial literacy is not a panacea for mitigating CFV. The propositions and their implications for marketing strategy, public policy, and consumer well-being offer a rich research agenda. The authors propose a measure of CFV—the probability that financial resources are insufficient to meet or exceed a harm threshold—for future empirical investigations.

The Impact of Payment Frequency on Consumer Spending and Subjective Wealth Perceptions

Abstract Payment frequency is a fundamental yet underexplored feature of consumers’ finances. As higher payment frequencies are becoming more prevalent, consumers are receiving more frequent yet smaller paychecks. An analysis of income and expenditure data of over 30,000 consumers from a financial services provider demonstrates a naturally occurring relationship between higher payment frequencies and increased spending. A series of lab studies support this finding, providing causal evidence that higher (vs. lower) payment frequencies increase spending. The effect of payment frequency on spending is driven by changes in consumers’ subjective wealth perceptions. Specifically, higher payment frequencies reduce consumers’ uncertainty in predicting whether they will have enough resources throughout a period, increasing their subjective wealth perceptions. As such, situational factors that reduce prediction uncertainty for those paid less frequently (e.g., the timing of consumers’ expenses, income levels) moderate the impact of payment frequency. The effects of payment frequency on subjective wealth and spending can occur even when objective wealth favors those with lower payment frequencies. More broadly, the current work underscores a need to understand how timing variations in consumers’ income impact their perceptions, behaviors, and general well-being.

Overconfidence and the Credit Card Debt Puzzle

This article investigates the credit card debt puzzle. Simultaneously holding credit card debt and liquid assets is puzzling given the sizeable difference between interest rates of debt and assets. However, this behavior is common—about 31% of households in the 2016 Survey of Consumer Finances. The cost of co-holding may be justified if consumers anticipate future restrictions in credit or if they need to maintain liquidity. Other existing explanations for co-holding include impulsive spending and low financial literacy. This research reveals a new explanation for the credit card debt puzzle: consumers’ overconfidence of their financial knowledge. Using a Coarsened Exact Matching method, we found that overconfident consumers were 20%–40% more likely to co-hold credit card debt and liquid assets.
