,Chapter 1: Digital Household Finance — Positioning
1.1 Corporate Finance & Household Finance
Household finance studies how ordinary households use financial instruments to reach their goals — the household-
level mirror image of the corporate finance studied in Part 1. The single biggest challenge in this field is the emotional
component of investing: people are not the fully rational decision-makers that classic finance assumes.
Three well-documented mistakes households systematically make:
— Underparticipation: households invest too little in financial markets in the first place (too much sits in
cash/savings accounts).
— Underdiversification: when households do invest, they hold too few different assets (e.g. skipping low-cost
diversified vehicles like ETFs in favour of a handful of individual stocks).
— Underusage of annuities: households systematically prefer a lump-sum pension payout over a monthly "for life"
annuity, even when the annuity would better match their actual retirement-income needs.
Two broad ways to address these mistakes:
Approach What it does Limitation
Teach people how to make better decisions Does not always work — education
Financial education
themselves alone often fails to change behaviour
Change the context: redesign the product Requires first understanding actual
Financial engineering or the choice environment so that people (not assumed) behaviour before it
naturally do better can be designed well
The two-step logic that runs through the whole course: first build a better understanding of actual human behaviour
(behavioural finance), then use that understanding to design better digital-era applications and products that improve
financial wellbeing.
1.2 Recent European Initiatives to Improve Financial Wellbeing
1.2.1 Belgian example — the Pensiontest: a tool that shows the trade-off between taking a pension as a lump sum
versus as an annuity, and visualises the risk attached to each choice.
1.2.2 Financial literacy: an EU Commission 2023 survey on financial literacy and self-awareness asked questions such as
what happens to bond prices when interest rates rise, whether a higher-return investment is likely to be riskier, and
whether respondents hold shares/ETFs/crypto. Key takeaways: people broadly grasp the risk/reward trade-off in the
abstract but disagree on what actually constitutes "risk"; people agree it makes sense to prepare financially and admit
they could use guidance; people are relatively comfortable using digital financial services, yet simultaneously have low
trust in advice — whether human or digital; and the overall financial literacy score leaves clear room for improvement.
1.2.3 Financial resilience: emerging trends (mobile apps, robo-advice, social media, crypto) are reshaping retail investor
behaviour, which raises the need for both financial literacy AND regulatory/supervisory oversight — though regulation
must be balanced carefully so that it does not stifle innovation.

and the EU economy becomes stronger options; unified cross-border markets;
and more competitive support for long-term saving goals
, Regulatory and supervisory initiatives focus on two goals: increasing comparability (e.g. comparison platforms like
Spaargids.be for savings, JustETF for ETFs) and reducing switching costs. ESMA (the EU's securities and markets
supervisor) oversees MiFID — the legislation governing trading and selling of financial instruments, including suitability
requirements — and is pushing to modernise today's largely semi-automated suitability process by incorporating
behavioural finance insights.
A live EU consultation is exploring how to simplify and standardise investor risk profiling (ideally so people could
complete it unaided, without needing an advisor's encouragement) and how to personalise and standardise asset
allocation recommendations across providers. Banks resist full standardisation/portability of client profiles between
institutions, since a bank's own view of the client is part of its competitive "added value" — sharing that data too freely
would make switching between banks too easy. The overarching goals are portability (letting a client's profile move
with them from one provider to another), reduced switching frictions, comparability, and a shift toward an "open
finance" framework — moving the emphasis away from products and toward the investor (appropriateness).
Conclusion of 1.2: interest in (digital) investing as part of household finance is rising; accessibility is growing, but this
can also introduce new, more systemic risks; and financial and digital literacy are becoming steadily more important.
