和经济没关系,可算成语,意思是快速估算法,約略的估計或單憑經驗來做的方法,經驗法則.

本意是小法宝、小窍门、经验法则之类的
个人对增长与收敛较熟悉，经济增长中的Rule of Thumb是罗默推算出来的，并经过了实证证明，大致是
Rule of Thumb: If an economy grows at g% we can show that it doubles roughly every 70/g years. So if an economy grows at 2% it will double every 35 years and if it grows at 7% it will double every 10 years.
呵呵，曼昆还写过My Rules of Thumb一文，列举了他的六个工作窍门（这里Rules of Thumb的意思就像是二楼所说）
Rule No. 1:Learn from the Right Mentors
Rule No. 2: Work With Good Co-Workers
Rule No.3: Have Broad Interests
Rule No. 4: Allocate Time and Crew
Rule No.5: Write Well
Rule No.6: Have Fun

sungmoo：
A rule of thumb is an easy-to-remember guideline that isn't necessarily a hard-and-fast rule or scientific formula but it's more than just a dumb guess. For centuries rule of thumb has been used as an estimated measurement by many craftsmen including carpenters, brewers, and tailors. The term referred generally to the length of the thumb from the joint to the tip, approximately an inch.
Or
A Rule of thumb is a procedure based on experience and common sense. It can also be used to refer to a general principle regarded as roughly correct but not intended to be scientifically accurate.

As a rule of thumb, economists believe the US economy needs to add about 150,000 jobs each month to absorb new workers joining the labour force.
