大家可唔可以幫我講解下答案的原因, 我不太明白
如果 講解得令我滿意的話,我會贈送40分 thx!Ina small college town, four microbreweries have opened in the last two years.Demonstrate the effect of these new market entrants on demand for incumbentfirms (microbreweries) that already served this market. Assume that the localcommunity now places a moratorium on new liquor licenses for microbreweries.How will this moratorium affect the long-run profitability of incumbent firms? ANSWER: The arrival of a new entrant should begraphically depicted by a leftward shift in the demand curves faced by allincumbent firms. If firms are able to make economic profits, these will be ableto be maintained in the long run if new entrants are not allowed.
