Instrumental variables (IV) estimation of a demand equation using time series data is shown to produce a weighted average derivative of heterogeneous potential demand functions. This result adapts recent work on the causal interpretation of two-stage least squares estimates to the simultaneous...

The nexus between debt and inequality has attracted considerable scholarly attention in the wake of the global financial crisis. One prominent candidate to explain the striking co-evolution of income inequality and private debt in this period has been the theory of upward-looking consumption...

According to the permanent income logic, individuals form expectations about their ability to produce in the long run and decide how much to consume today according to their forecasts.This paper documents that deviations of current consumption from its permanent level warranted by...

What model features and calibration strategies yield a large average marginal propensity to consume (MPC) in heterogeneous agent models? Through a systematic investigation of models with different preferences, dimensions of ex-ante heterogeneity, income processes and asset structure, we show...

This paper uses housing returns to estimate the elasticity of intertemporal substitution (EIS) in consumption for fifteen advanced economies over the postwar period 1950 − 2015. As housing is the main asset for the majority of households, returns on housing are better suited to estimate the...

We develop an income shock classification taxonomy that classifies income changes into 9 categories based on the magnitude, direction and permamency of the income change. Using 01/2017 - 06/2022 bank transaction data of Belgian employees and workers, we apply this classification on labour income...

We characterize optimal consumption policies in a recursive intertemporal utility framework with local substitution. We establish existence and uniqueness and a version of the Kuhn-Tucker theorem characterizing the optimal consumption plan. An explicit solution is provided for the case when the...

Economic growth tends to stimulate fundamental changes in consumption patterns as consumers who get rich tend to spread their spending more evenly across a wider variety of goods and services. Comparing cross sectional spending patterns across rich and poor countries, we investigate how this...
