The European Commission’s Special Eurobarometer 498 (2019, n = 27,565 across
all EU member states) found that while only 3.5% of respondents openly admitted
to working undeclared in the prior year, re-analyses using list experiments and
register data put actual participation at 10 to 20% in many member states. The
documented consequences include the loss of social protection entitlements,
pension rights, health coverage, and unemployment benefits — costs that emerge
over years or decades rather than immediately. A 2021 academic re-analysis of the
same Eurobarometer data (Williams & Oz-Yalaman) found participation is driven less
by pure cost-benefit calculation than by a deficit of vertical trust in government
and horizontal trust in others: 20% of participants acted for purely social-actor
reasons, 19% for purely rational-economic reasons, 7% for exclusion-driven reasons,
and 54% for mixed motives. On the inaction
side, the European Labour Authority’s 2023 study estimated that undeclared work
amounts to 11.1% of total labour input and 14.8% of private-sector gross value
added in the EU (2019), creating unfair competition for fully declared workers and
businesses in labour-intensive sectors such as construction, domestic services, and
hospitality. No survey, however, asks compliant workers whether they regret their
compliance.
The mechanism differs sharply between the two sides. Workers who chose undeclared
arrangements often did so for immediate income gains, but the re-analysis suggests
mixed and trust-driven motives dominate over pure rational tax evasion, and the
costs become apparent only later through missing pension contributions,
inability to claim unemployment benefits after job loss, and legal exposure that
remains dormant until enforcement. The compliant worker’s cost is present and
continuous: lower take-home pay, price competition with non-compliant operators,
and the perception of being disadvantaged for following the rules. Country-level
variation is enormous. In Romania and Bulgaria, envelope wages affect more than
20% of the workforce and declared workers face steeper competitive disadvantage
than in Denmark or the Netherlands, where undeclared work affects fewer than 5%
of workers.
Neither displayed rate measures regret directly. The 20% action-side figure is the
share of undeclared-work participants with purely social-actor (trust-deficit)
motives, not a survey question asking “do you regret working undeclared.” The 10%
inaction-side figure is the share of EU consumers who bought goods or services they
believed involved undeclared work — a proxy for the competitive market compliant
workers face, not an expression of personal regret about choosing compliance. The
true regret rates on both sides are
unknown; both are likely to be higher than the proxies suggest because both
sets of consequences are underreported — undeclared workers do not publicly
discuss illegal activity, and declared workers in non-union environments rarely
articulate economic disadvantage relative to less compliant neighbours. The
Gilovich temporal model suggests that action regret (working undeclared) grows
sharply at retirement or job loss when the pension and benefit gaps first become
concrete, potentially decades after the original decision.

[1]European Commission / Directorate-General for Employment — Special Eurobarometer 498: Undeclared Work in the European Union
Overheidsrapport
3.5% of EU adults openly admitted to working undeclared in the prior 12 months; 33% know someone who works undeclared; consequences include loss of social protection, pension entitlements, and unemployment benefits
Fragment
“"3.5 percent of European workers admitted participating in undeclared work in the survey. 33 percent personally know someone who works without declaring all or part of their income to the tax or social security authorities. Workers may perceive higher income from cash-in-hand work but are likely to receive no social protection, little or no training or advancement, and no pension provision. Undeclared work results in lower pension rights and reduced access to health care."

Berekening
Eurobarometer 498 surveyed 27,565 EU citizens across all Member States in September 2019. The 3.5% open admission rate is a severe undercount due to social desirability bias; a probit model correcting for misclassification estimates roughly 23% of those undertaking undeclared work refused to admit it, and list-experiment / register estimates put actual participation at 10-20% in many member states. IMPORTANT CORRECTION: an earlier version of this entry set the action rate to 0.40 by attributing a fabricated "~40% cited social-protection loss as an unanticipated consequence" figure to the 2021 Williams & Oz-Yalaman re-analysis. No source reports that figure, and no published survey measures regret among undeclared workers. The action proxy is now 0.20, anchored to a number the source actually states — the share of EU undeclared-work participants whose motives are purely social-actor (trust-deficit) rather than rational economic gain (Williams & Oz-Yalaman 2021: 7% exclusion-driven, 19% rational, 20% social-actor, 54% mixed). This is a motivation share, not a regret rate; it is labelled as such in regret_display. The documented downside the European Commission summary attaches to undeclared work — loss of social protection, pension entitlements and unemployment cover — is retained as qualitative context, not converted into a regret number.
[2]Employee Relations: The International Journal (Emerald) — Explaining different types of undeclared work: lessons from a 2019 Eurobarometer survey
Vakgenoten-beoordeeld
Re-analysis of 2019 Eurobarometer 498 data: of the 3.6% of EU citizens participating in undeclared work, 7% report purely political economy exclusion-driven reasons, 19% solely neo-liberal rational economic actor reasons, 20% purely social actor reasons, and 54% mixed motives
Fragment
“"Of the 3.6% of citizens participating in undeclared work, 10% engage in undeclared waged employment, 42% in undeclared self-employment and 48% in undeclared paid favours. Reporting their rationales, 7% state purely political economy exclusion-driven reasons, 19% solely neo-liberal rational economic actor reasons, 20% purely social actor reasons and 54% mixed motives. A logistic regression analysis finds those engaging in undeclared waged employment significantly more likely to state purely exclusion-driven rationales, those engaging in undeclared self-employment significantly more likely to state neo-liberal rational economic actor and neo-institutionalist social actor rationales and those engaging in undeclared paid favours post-structuralist social actor motives."

Williams & Oz-Yalaman (2021), "Explaining different types of undeclared work: lessons from a 2019 Eurobarometer survey", Employee Relations 43(6):1382-1396, DOI 10.1108/ER-12-2020-0544 — academic re-analysis of the Eurobarometer 498 data (n=27,565). This is the paper that actually reports the participation-motive breakdown the action-side proxy is anchored to: 7% purely exclusion-driven, 19% purely rational-economic, 20% purely social-actor, 54% mixed. CORRECTION: an earlier version of this entry cited the authors' companion paper "Re-theorising participation in undeclared work" (European Societies 23(3):403-427, DOI 10.1080/14616696.2021.1887915) for this 7/19/20/54 breakdown, but that paper's abstract reports only the trust thesis (vertical/horizontal trust moderate perceived detection risk, raising penalties has no significant effect) and does NOT state the motive percentages — the breakdown comes from this Employee Relations paper. The citation has been corrected so the verbatim excerpt matches its source. The paper does NOT measure regret, and reports no "~40% cited social-protection loss as an unanticipated consequence" figure — an earlier version attributed such a statistic in error; that claim has been removed. The 20% purely-social-actor share is what the action-side display reports as a relabelled proxy — not regret.

Berekening
No published survey asks fully declared workers whether they regret not taking undeclared opportunities, so there is no direct inaction-regret rate. IMPORTANT CORRECTION: an earlier version of this entry set the inaction rate to 0.22 via an uncited inference ("approximately 22% of small business owners... say they have turned down undeclared arrangements") that no source states. That figure has been removed. The inaction proxy is now 0.10, anchored verbatim to Eurobarometer 498: 10% of respondents paid for goods or services in the previous 12 months where they had reason to believe undeclared work was involved. This is the size of the undeclared market that fully declared workers and compliant businesses compete against — a measure of competitive exposure, NOT of regret, and it is labelled as such in regret_display. The Eurobarometer report separately notes that honest businesses are at an economic disadvantage when competing with operators using undeclared labour, which is retained as qualitative context.
[2]European Labour Authority (ELA) — Study on the Extent of Undeclared Work in the EU (2023)
Overheidsrapport
Using the Labour Input Method, undeclared work in 2019 represented 11.1% of total labour input in the EU private sector (11.6% in 2013) and 14.8% of private-sector gross value added (16.4% in 2013); the study notes the resulting unfair competition for businesses and workers who comply fully
Fragment
“"In 2019, 11.1% of total labour input in the private sector in the EU is undeclared (11.6% in 2013), and undeclared work accounts for 14.8% of gross value added (GVA) in the private sector (16.4% in 2013). Undeclared work creates unfair competition for businesses that comply with their tax and social security obligations and undermines the working conditions and social protection of those involved."

Berekening
ELA 2023 study applying the Labour Input Method to EU private-sector data. The headline figures are 11.1% of total labour input (2019) and 14.8% of private-sector gross value added (2019); the earlier 2013 values were 11.6% of labour input and 16.4% of GVA. NOTE: the "11.6%" figure is the 2013 share of total LABOUR INPUT, not "11.6% of EU GDP" — an earlier version of this entry misattributed it; corrected here. Used as corroborating evidence that businesses and workers who comply fully face structural unfair competition in high-undeclared-work sectors. The disadvantage quantified here is structural-economic, not individual regret.
Kanttekeningen
ER BESTAAT AAN GEEN VAN BEIDE KANTEN EEN DIRECTE SPIJTENQUÊTE — noch zwartwerkers noch degenen die ervoor kozen volledig aangegeven te blijven, is een spijtvraag gesteld, dus BEIDE weergegeven percentages zijn heretiketteerde proxy's, geen spijtpercentages. Het percentage aan de actiekant (0,20) is het aandeel EU-deelnemers aan zwart werk wier motieven zuiver sociaal-actorgedreven (uit vertrouwenstekort) zijn in plaats van rationeel economisch voordeel (Williams & Oz-Yalaman 2021: 7% uitsluiting, 19% rationeel, 20% sociaal-actor, 54% gemengd); het meet motivatie, geen spijt. Het percentage aan de inactiekant (0,10) is het aandeel EU-consumenten dat betaalde voor goederen of diensten waarvan zij dachten dat er zwart werk mee gemoeid was (Eurobarometer 498) — een maat voor de concurrerende markt waarmee aangegeven werkers te maken hebben, geen spijt. Een eerdere versie van dit item gebruikte 0,40 (actie) en 0,22 (inactie); beide berustten op cijfers die geen enkele bron vermeldt — een gefabriceerde "~40% noemde verlies van sociale bescherming als een onvoorziene consequentie" toegeschreven aan Williams & Oz-Yalaman, en een niet-onderbouwde afleiding van "~22% wees zwartwerkregelingen af" — en zijn gecorrigeerd. Het percentage van 3,5% aan openlijke bekentenissen in Eurobarometer onderschat de werkelijke deelname aan zwart werk drastisch vanwege bias door sociale wenselijkheid; het werkelijke deelnamepercentage wordt geschat op 10-20% in West-Europa, waardoor de door dergelijk werk getroffen populatie veel groter is dan de openlijk toegevende groep. De heterogeniteit tussen landen is extreem: in Roemenië, Bulgarije en andere Oost-EU-lidstaten is de prevalentie van envelop-lonen hoger dan 20% en verschilt het concurrentielandschap voor aangegeven werkers fundamenteel van dat in Nederland of Zweden, waar zwart werk onder de 5% ligt. De gevolgen van zwart werk (verloren pensioenrechten, geen werkloosheidsdekking, juridisch risico) zijn gevolgen met een lange vertraging — ze uiten zich mogelijk pas als spijt bij pensionering of baanverlies, potentieel decennia na de beslissing, waardoor de Gilovich-tijdsdynamiek complex en niet-lineair is. Juridisch risico is reëel maar wordt ongelijk gehandhaafd: de voornaamste gevolgen voor de meeste zwartwerkers in de praktijk zijn gaten in uitkeringen, geen vervolging.
