question
If buyers think the price of potato chips will be higher next week, today we would expect to see
answer
an increase in demand
Because it's buyers having the expectation, this is a demand shifter. As buyers think potato chips will be more expensive next week, they'll want to buy more now, increasing demand (shifting the demand curve to the right) today. (An increase in quantity demanded of potato chips can ONLY be caused by a decrease in price of potato chips.)
