Markets with Frictions

Determine the friction coefficient.
Choose a coefficient of friction equal to 0.13.
Multiply these values by each other: 250 N * 0.13 = 32.5 N.

If it talks to your hart you may consider ideas of endless scope. Such as Economy, Population and interactions between.

Start here with economy, considering:
..
Search costs are the costs incurred by a consumer in identifying a firm's product and price, regardless of whether the consumer then buys the product from the searched firm or not.

Switching costs are the costs incurred by a consumer in changing suppliers that do not act to improve the consumer's prepurchase information.

Nice quote:
The universe of financial market frictions
can be partitioned in many ways, so no
structure can hope to be complete or
very precise.
