In a model calibrated to match micro- and macroeconomic evidence on household income dynamics, we show that a modest degree of heterogeneity in household preferences or beliefs is sufficient to match empirical measures of wealth inequality in the United States. The heterogeneity-augmented...

This paper aims to test the microfoundations of consumption models and quantify the macro implications of heterogeneity in consumption behavior. We propose a new empirical method to estimate the sensitivity of consumption to permanent and transitory income shocks for different groups of...

This paper presents two models of consumption for the primary purpose of forecasting consumption expenditure growth in New Zealand. The models, which are consistent with a range of consumption functions including the life-cycle and permanent income hypothesis, are error correction models with...

We use sizeable lottery prizes in Norwegian administrative panel data to characterize households’ marginal propensities to consume (MPCs). Our main contribution is to document how MPCs vary with household characteristics and prize size, and how lottery prizes are spent and saved over time. We...

We use administrative and survey-based micro data to study the relationship between cognitive abilities (IQ), the formation of economic expectations, and the choices of a representative male population. Men above the median IQ (high-IQ men) display 50% lower forecast errors for inflation than...

Intertemporal substitution is at the heart of modern macroeconomics and finance as well as economic policymaking, but a large fraction of a representative population of men - those below the top of the distribution by cognitive abilities (IQ) - do not change their consumption propensities with...

The well-documented positive correlation between income risk and wealth was interpreted as evidence for high amounts of precautionary wealth in various studies. However, the large estimates emerged from pooling non-entrepreneurs and entrepreneurs without controlling for heterogeneity. This paper...

Various studies have interpreted a positive correlation between income risk and wealth as evidence for large precautionary savings. However, the high estimates emerged from pooling non-entrepreneurs and entrepreneurs without controlling for heterogeneity. This paper provides evidence for Germany...

Much analysis in macroeconomics empirically addresses economy-wide incentives behind consumer/investment choices by using insights from the way a single representative household would behave. Heterogeneity at the micro level can jeopardize attempts to back up the representative consumer...

Unconventional fiscal policies incentivize households to accelerate consumption by generating future consumer price ination, and offer an alternative to unconventional monetary policy (Correia et al. (2013)). We use a natural experiment to study the causal effect of unconventional fiscal...
