不好意思,以下是题目AAB015: The following appeared in a research paper written for an introductory economics course: "For the past centure, an increase in the number of residential buiding permits issued per month in a particular region has been a reliable indicator of coming improvements to that region's economy. If the monthly number of residential buiding permits issued rises consistently for a few months, the local unemplayment rate almost always falls and economic production increases. This well-established connection reveals an effective method by which a regional government can end a local economic downturn: relax regulations governing all construction so that many more building permits can be issued." |
