Changes in dividends impact household consumption. Capital gains also have an impact, but a smaller one than dividends. The magnitude of the impact depends on household wealth, with consumption rising proportionately higher among comparatively less affluent households.
The findings are based on an analysis of Swedish households. Sweden was chosen because the country levied a wealth tax between 1999 and 2007. This provided the study’s authors with information about portfolio holdings, debt obligations and real estate transactions. Information on income, municipality of residence, demographics and wealth was also available. Households were categorized by wealth levels: bottom 5% to 50%, 50% to 70%, 70% to 90%, 90% to 95% and the top 95% to 100%.
Consumption was defined as the aftertax labor and financial asset income less interest payments, change in debt, change bank account balances, and savings and pension contributions.
Households whose wealth ranked in the bottom half consume $0.51 of every dollar of change in dividend income. They also react to capital gains, consuming about $0.33 for every dollar of capital gains.
At higher levels of wealth, the impact on consumption is smaller. A change in dividends led to about a $0.09 difference in consumption for the wealthiest 10% of households. Every dollar of capital gains was linked to between a $0.05 and $0.06 increase in consumption. Overall, as wealth increased, the proportionate effect dividends and capital gains had on consumption decreased.
One reason dividends may have a bigger impact on consumption than capital gains is how investors view them. Changes in dividend income are more persistent than changes in capital gains. As such, the reaction to the dividends would rationally be stronger if households viewed dividend income as being separate from capital gains income.
Households also do not necessarily sell their stocks to realize the capital gains. Rather, they adjust their savings rate. To the extent households are not selling stocks that have risen in price, the impact on consumption will be less than that of an increase in the amount of dividend income received.
