We use panel data on a complete inventory of household spending and assets to estimate the spending response to the sharp and largely unexpected declines in house values that occurred in the Great Recession. Our study complements the existing literature on this topic by relying exclusively on longitudinal micro data on both household wealth and expenditure. Our data span the period 2002-2012, allowing us to separate trends in spending from innovations in response to unexpected wealth changes. We find the marginal propensity to consume out of an unexpected housing wealth change to be 6 cents per dollar among older American households. (JEL D12, D14, E21)The quantitative relationship between an unexpected wealth loss or gain (a wealth shock) and consumption can sharpen our understanding of intertemporal decisions. In the absence of constraints, it reveals the choice between present and future consumption and shows how consumption is traded off against other uses of wealth such as leisure. In the presence of constraints, it shows the realized ability to smooth consumption. Further, from a macro perspective, the average response of households to wealth shocks has the potential to exacerbate booms or busts in the economy. Windfall gains in the housing or stock market may lead to spending increases, possibly contributing to bubbles in those markets. Unanticipated wealth losses may cause spending reductions, adding to the deflationary forces that were responsible for the losses. Consequently, policy makers have considerable interest in the consumption response to a wealth shock.In this article, we use household-level data on wealth changes and spending from before, during, and after the Great Recession to estimate the response of household spending to wealth shocks.
