- With the cash cushion that was built during the pandemic losing its fluff, it is a good time to revisit consumption behavior, which is starting to lose steam in Europe and the US. The wealth effect is a behavioral economic theory that suggests that asset-price fluctuations affect household spending. However, we find that the income effect overshadows the wealth effect in France, Germany, Spain and the US. The marginal propensity to consume (MPC) per 1% difference in disposable income is 0.21% for France, 0.71% for Germany, 0.78% for Spain and 0.35% for the US. This highlights the importance of supporting household income as a tailwind to attain the much-desired economic soft landing.
- However, the wealth effect of housing prices clearly dominates that of stock market prices almost by a factor of ten in France, Germany, Italy, Spain and the US. For continental Europe, keeping inflation at bay holds the answer to consumption, while in the US the prospect of diminishing wealth weighs on the Fed’s hopes for a stormy soft landing.
FEATURE - OVERVIEW:
Consumption: what’s wealth got to do with it?
KEY DEVELOPMENTS
US GDP data, gasoline price pressures, high-yield corporate spreads ignore recession bells
- US GDP data came out stronger than expected, but underlying cracks appear—Household and government spending surprised on the upside but we still expect a recession in Q1 2023 in line with recent hard and soft data. This deteriorating momentum should comfort the Fed in slowing the pace of rate hikes during the FOMC meeting next week.
- No relief in sight for gasoline prices—As the European embargo on Russian diesel is about to begin, refiners' margins are also increasing and pointing towards expensive fuel for longer.
- High yield – High-yield investors have missed the recession memo and are already pricing in the recovery phase.
US economy ends 2022 on a strong footing, but more and more cracks appear under the surface
US GDP overshot expectations in Q4 2022, growing +2.9% q/q annualized (after +3.2% in the previous quarter). This is more than twice the pace we expected in our December 2022 scenario. Household consumer expenditure (+2.1%) and government consumption (+3.7%) both surprised on the upside. However, other components of expenditures were weak, notably residential investment (-19%), and business investment growth (+0.7%) slowed markedly from the previous quarter. Net trade and inventories provided large boosts to GDP growth, with the fall in imports outstripping the fall in exports.
Soft data point to a recession beginning in Q1 2023, with hard data catching up fast. Business surveys released in January suggest the economy is currently entering a recession (see Figure 1), consistent with our forecasts. However, the surveys are probably overestimating the depth of the downturn as business sentiment tends to deteriorate excessively when gloomy talk of recession increase. Meanwhile, hard data released for December 2022 show that economic momentum was rapidly fading, with both retail sales and industrial production showing outright declines. We expect GDP to contract -0.8% (annualized) in Q1 2023.


Oil prices may have decreased, but there is no relief in sight for the consumer

Some asset classes continue to ignore the recession memo


Fluctuations in asset prices – real or financial – rarely come without any other macroeconomic developments. To measure both the income and wealth effects on consumption, we drew from Caceres (2019) [1] and his macro estimations to measure both impacts in France, Germany, Italy, Spain and the US. Generally, we find that the income effect overshadows the wealth effect in all countries and it is statistically significant, as expected. The marginal propensity to consume (MPC) per 1% difference in disposable income is 0.21% for France, 0.71% for Germany, 0.78% for Spain and 0.35% for the US. These income effects highlight the importance of supporting household income as tailwinds to attain the much-desired soft landing.
Another feature that is common for most countries is that the wealth effect of housing prices clearly dominates that of stock market prices almost by a factor of ten in France, Germany, Italy, Spain and the US, as shown in the table below. This is in line with expectations as stock market prices are more volatile than real estate prices.[2] Looking at home sales turnover or the structure of savings might hold some of the answers for further analysis. For Germany, we find that the wealth effects materialize with a lag of two years, while for the US and France there is both a lagged and instantaneous effect.

[2] Our regression results are inconclusive for Italy and Spain, we would need to further research the consumption behavior to better assess the impact of changes in asset prices on their decision-making process


Using our macroeconomic expectations and forecasts for asset prices, while drawing from the income and wealth effects described above, we estimate real consumption growth in 2023 and 2024. For continental Europe, we are mostly looking at flat consumption growth in line with the region’s economic slowdown. Because disposable income has the stronger effect, it appears that the inflation genie holds the answer as households are impacted by high prices and the economic effects of the war in Ukraine. For the US, as we expect inflation to come down sooner, despite the strong labor market, consumption might lose steam and park for the next two years at the stagnation station because of the impact of asset prices on households’ internalized net worth function.
