How would you reply to a one-off change in your revenue? For instance, how would you react to somebody handing you £500? All through the pandemic a big group of UK households had been requested this hypothetical query in a survey. Households had been additionally requested for different info, for example about their debt, financial savings, and expectations for the longer term, giving us a possibility to unpick their responses. We’d count on households who’re involved about their monetary future to be much less wanting to spend than others, preferring to save lots of up for rainier days. In a new paper, we discover the other consequence: involved households would in reality spend round 20% greater than others.

Family spending out of revenue transfers has been low throughout the pandemic

The Covid-19 (Covid) pandemic has introduced renewed curiosity to understanding how family spending responds to revenue adjustments. The disaster hit incomes for a big share of households and lockdown restrictions meant that the autumn in combination spending was important, with massive variations throughout households. Family spending behaviour might be a important determinant of the form of the restoration.

New information units have allowed economists to estimate households’ marginal propensity to devour (MPC) – the share of an increase in revenue {that a} shopper spends moderately than saves – fairly swiftly throughout the pandemic. The out there proof factors to households principally saving or paying down debt when receiving a one-off fee. However there’s proof that the MPC out of constructive revenue shocks is largest for low-income and liquidity-constrained households, and for households who suffered larger revenue falls relative to their pre-pandemic revenue.

There’s much less empirical proof and consensus in regards to the hyperlink between family expectations and the MPC. In line with precautionary financial savings fashions, financially involved households are likely to have decrease MPCs, in order to construct up financial savings to mitigate future unfavorable revenue shocks. There’s some proof for the United States and euro space in that route. However others discover little position for people’ macroeconomic expectations in explaining variations in MPCs. And there’s proof for the UK that people who count on their monetary scenario to worsen or a job loss within the subsequent three months really report a better MPC out of a hypothetical switch. On this publish we due to this fact dig deeper into the hyperlink between monetary considerations and family spending.

Spending out of a switch from family survey information

We use granular information masking a balanced panel of seven,000 UK households collected within the Understanding Society Covid-19 Research. Understanding Society is the UK’s important longitudinal family survey. The Covid Research was launched to seize experiences of a subset of those households throughout the pandemic. Our variable of curiosity, the MPC, is extracted from a number of questions in July 2020, November 2020 and March 2021 which ask households what they’d do over the following three months in the event that they had been to obtain a one-time hypothetical switch of £500.

Chart 1 exhibits that round 78% of households wouldn’t change their spending in response to a one-time fee of £500. Round 18% would spend extra, whereas roughly 4% would spend much less. The responses are comparatively steady throughout the three survey waves. We then compute the family’s MPC because the reported pound consumption change divided by £500. We assume that MPCs fluctuate between zero and one, in order that households who reported they’d spend much less or the identical are recoded as having an MPC of zero. We discover that the common elicited MPC throughout surveys stands at solely 11%.

Monetary considerations throughout the pandemic

The surveys additionally contained questions on family expectations, which permit us to discover the hyperlink between monetary considerations and the MPC. These expectations relate to households’ monetary scenario within the subsequent three months, aligning with the time horizon of the MPC query. Our important measure of economic considerations focuses on households’ perceived probability of getting difficulties in paying payments and bills within the subsequent three months (starting from 0%–100%).

In our baseline regressions we rework the monetary considerations variable right into a binary one, taking the worth of 1 if the family’s anticipated likelihood of economic misery is above the median within the pattern, and nil in any other case.

What determines monetary considerations?

We hyperlink the Covid surveys to the principle survey to extract necessary pre-crisis family traits, resembling mortgage debt and financial savings. We then discover which traits correlate with monetary considerations by working probit panel regressions throughout the three surveys. We embody a big set of family traits: socio-demographic variables; monetary traits; subjective present monetary scenario; employment info; advantages and well being considerations.

We discover that households which can be involved about not with the ability to pay their payments within the brief time period are considerably extra prone to fall into varied teams: already involved about their present monetary scenario; liquidity constrained; belong to low-income teams; renters or mortgagors; youthful, male, and ethnic minorities; furloughed; reliant on advantages; or employed in industries extra closely impacted by the pandemic.

The hyperlink between monetary considerations and spending

We then run a number of panel regressions to uncover variations in MPCs throughout households throughout the pandemic. Our dependent variable is the elicited MPC, ranging between 0 and 1 and our key explanatory variable is the binary monetary considerations variable. We embody plenty of family controls, resembling financial savings, tenure, revenue and age, which could be anticipated to correlate with a family’s spending selections. Along with our monetary considerations variable, which signifies whether or not a family believes they are going to be worse off financially in three months’ time, we additionally embody a variable indicating whether or not a family is discovering it troublesome to handle financially now. This enables us to tease out the position of short-term expectations about future monetary difficulties. If we didn’t management for a family’s present monetary scenario outcomes may simply replicate that some households are already struggling and so reply extra to an revenue shock.

Monetary considerations over the brief time period, play a key position in explaining variations in MPCs throughout households throughout the pandemic. We discover that financially involved households have an MPC that’s 2.3 proportion factors bigger than households who usually are not involved (left bar in Chart 2). That’s 20% greater than the pattern common. This result’s strong to plenty of checks, resembling different measures of economic considerations, controlling for health-related considerations, and to small adjustments to the design of the MPC query.

Notes: Estimates from a random results mannequin on the particular person stage, the place the dependent variable is the elicited MPC. Controls for full set of family traits. Customary errors in parentheses clustered on the particular person stage. Asterisks, *, ** and *** denote statistical significance on the 10%, 5% and 1% ranges.

We additionally examine whether or not previous spending cuts, unfavorable revenue shocks, mortgage debt, and the labour market scenario clarify why financially involved households have bigger MPCs. We may solely discover some tentative proof that a part of our consequence could also be pushed by completely different shares of discretionary spending and reliance on advantages, however that is unlikely to play a big position.

We adapt our baseline specification to utilize the truth that our monetary considerations variable ranges from 0% to 100%. We discover that households which can be reasonably involved, within the 1%–50% likelihood vary, are driving our important outcomes (Chart 2). This means that, so long as the subjective likelihood of being in monetary misery sooner or later isn’t that giant, involved households will are likely to spend a bigger fraction of the revenue windfall than different households. Against this, households which can be sure they will be unable to pay their payments (100% likelihood) show the smallest MPC; these households save a bigger fraction of the switch to arrange for tougher instances forward.

Whereas our outcomes could also be shocking from the attitude of a classical consumption mannequin, they’re much less shocking from a behavioural perspective. In behavioural fashions households could compartmentalise revenue and spending into completely different ‘psychological accounts’ and finances inside these to assist make trade-offs and act as a self-control system. Financially involved households could be extra prone to finances and deal with funds inside every tagged psychological account as distinct and imperfectly substitutable, making them extra prone to spend out of a switch. There’s additionally proof that completely different preferences can drive variations in consumption behaviour. As an illustration, impatience could lead households to convey consumption forwards, and may correlate with a better likelihood of turning into financially distressed in future.

Now we have proven that financially involved households are related to bigger MPCs out of constructive revenue shocks. However what about unfavorable revenue shocks? Sadly the survey didn’t embody questions on an revenue fall situation. We thus examine whether or not financially involved households that confronted revenue decreases throughout the pandemic had been extra prone to lower their spending than unconcerned households that additionally skilled falls. Our outcomes recommend that financially involved households who had unfavorable revenue shocks certainly lower consumption greater than unconcerned households, indicating that bigger consumption responses of the previous group will not be unique to eventualities of constructive revenue shocks.


We used survey information throughout the pandemic to discover how households who’re involved about their monetary future reply to a hypothetical constructive revenue shock. We discover that, opposite to expectations, involved households intend to spend round 20% greater than others. Households which can be reasonably involved, moderately than those that are sure they will be unable to pay their payments within the close to time period, drive our important outcomes.
