the searcher will ask the comrade's employer for a job. The employer will take on the new
worker if his last period's labor input does not exceed his current input target.
Store search is undertaken by every person. The searcher first asks a "soulmate"
(someone with the same consumption goods) for his effective retail prices, and then asks
a randomly chosen shop if it has a posted price for one of the searcher's consumption goods.
For each of his consumption goods, the searcher decides to switch, to either the soulmate's
shop or to the randomly located shop, or decides to stay with his current shop, depending
on which choice yields the lowest effective price.
