Abstract:
I show that after accounting for predictable variation arising from movements
in real interest rates, preferences, income shocks, liquidity constraints and
measurement errors, volatility of household consumption in the US increased
between 1970 and 2004. For households headed by nonwhite
and/or poorly educated individuals, this rise was significantly larger. This
stands in sharp contrast with the dramatic fall in instability of the aggregate
U.S.
economy over the same period. Thus, while aggregate shocks affecting households
fell over time, idiosyncratic shocks increased. This finding may lead to
significant welfare implications.
Abstract:
We study whether the increased income uncertainty in the US over the
last quarter-century had a negative impact on household welfare by looking at
variability of household consumption growth. We are particularly interested in
understanding the effect of greater uncertainty on the liquidity constrained
households. We study the evolution of liquidity constraints in the US in the Panel
Study of Income Dynamics, greatly extending Jappelli et.al (1998) methodology on how to construct such measures
using information from the Survey of Consumer Finances. We find that although
household indebtedness increased substantially, reflecting greater availability
of credit, there was no decline in the proportion of liquidity constrained
households between 1983 and 2007. Applying methodology developed in Gorbachev
(2009), we find that the evolution of consumption volatility for the liquidity
constrained households increased by economically and statistically more than
for the unconstrained households. This increase was lower than that of family
income volatility for these groups. Nevertheless, the welfare cost to society
is substantial: we estimate that an average household would be willing to
sacrifice 2.35 percent of nondurable consumption per year to lower consumption
risk to its 1984 levels.
- Volatility of
Housing Consumption. (with Brendan O'Flaherty)
Abstract:
The aim of the project is to design a theoretical model in which homelessness
is an endogenous state that arises in a dynamic stochastic environment. The
ultimate goal is to understand whether homelessness spells, entrances and exits
could be predicted and if so what information is necessary; and to design and
evaluate a homelessness prevention program in a dynamic and stochastic
environment. Examples of the questions we want to answer are: Should borrowing
constraints be relaxed so that people can borrow their way out of homelessness
today, or will relaxing borrowing constraints allow people to over-consume
today and so borrow their way into homelessness tomorrow? Should precautionary
savings be encouraged so that people have cushions to withstand future shocks,
or will savings just delay entry into homelessness? What interventions
will affect the probability of becoming homeless and how will they affect
behaviour? How will interventions affect incentives to save and to consume
before homelessness prevention programs kick in?
