Hmm. Not off the top of my head. The intuition is pretty straightforward though. Imagine the difference between doubling total amount of money in the economy by either:

a. doubling the amount of money each individual person has.

b. distributing that new money evenly across every person.

In the former case, the demand curve would get steeper, no? And in the latter case, it would get flatter.

In case a, you'd decrease the price elasticity of demand and people would have an incentive to raise prices. You'd have inflation.

In case b, you'd increase the price elasticity of demand providing an incentive for producers to keep their prices lower and compete with each other on price.

Of course it all depends on where on the demand curve we're talking about. But for many of the goods we produce, their market-clearing prices are at a quantity such that they would benefit from an additional even distribution of income to every person.
