“How Does Income Inequality Affect
Market Outcomes in Vertically Differentiated Markets?”, forthcoming in the International Journal of
Industrial Organization.
Abstract:
The distribution of consumer incomes is a key factor
in determining the structure of a vertically differentiated industry when
consumer's willingness to pay depends on her income. This paper computes the
Shaked and Sutton (1982) model for a lognormal distribution of consumer incomes
to investigate the effect of inequality on firms' entry, product quality, and
pricing decisions. The main findings are >>>>

“From Consumer Incomes to Car
Ages: How the Distribution of Income Affects the Distribution of Vehicle
Vintages” Working Paper, October
2010 (original draft from March 2008).
Abstract:
This paper studies the relationship between consumer
incomes and ages of the durable goods consumed. At the household level, it
presents evidence from the Consumer Expenditure Survey of a negative
correlation between incomes and ages of the vehicles owned. At the aggregate
level, it constructs a dynamic, heterogeneous agents, discrete choice model, to
study the relationship between the distribution of consumer incomes and the
distribution of vehicle vintages. >>>>

4. “Exploring Innovation with Market
Concentration and Consumer Income in Dynamic
Markets”, joint with Mei Lin and Andrew Whinston, Proceedings of the
Seventh Workshop on e-business (WeB) 2008,
Abstract:
Our study examines the disruptive innovations
that arrive from outside of the industry through computational analyses that
connect innovation rate to market concentration and consumer income in a
dynamic setting. The findings show that a market of fewer incumbents (higher
concentration) generates less innovations due to the reduced innovation premium
and shortened length of incumbency; however, the equilibrium innovation rate
increases in the market share of the top firm, due to enhanced innovation
premium. We also find that more high-income consumers stimulate innovation.
Lastly, higher consumer welfare and aggregate welfare are found in a more
innovative market in the long term.
