Abstract
We analyze the result of
allowing a risk averse trader to split his order among
risk averse market makers. We find that the market makers’ aggregate expected utility of profit can increase with the number of market markers and
that the aggregate liquidity always increases with it.
Despite this latter finding,
we show that the cost of trading for the traders increases with the number of
market makers as measured by their aggregate expected utility of profit. The
larger the market makers’ risk aversion, the bigger that cost is. We also find
that when the number of market makers tends to infinity, their aggregate expected utility of profit tends to zero. We also obtain that the market makers’
individual and aggregate expected utility of profit can increase with their risk
aversion and that the trader’s expected utility of profit can increase or decrease with the market makers’ risk aversion. We offer a potential answer to
the ongoing debate concerning the dealers’ competitiveness. Indeed, risk
aversion reduces competition between market
makers as it acts as a commitment for market makers to set higher prices. This commitment is higher the
higher the risk aversion
