Total = 82 marks ________________________________________________________ ** Allowed a regular calculator ** ** Very literal about her answers, if its two marks, need two points ** ** Write in short form ** ** Presentation questions are all in True/False ** ** NO UTI ** ** She likes giving E. answers that combine two answers, ELIMINATE incorrect answers first ** ** Be sure to know SOLOW ** ex. What curve will shift and what way, maybe why. Some say “State” meaning no answer needed. Others have ‘explain briefly’. ** Check TRUE/FALSE underline key words (always, must, etc) ** ** We do need to know similarities and differences between Solow and Harrod-Domar Model ** ** Growth accounting formula, Solow formula, Harrod-Domar, write them down ** ** Drawing graphs helps ** --OFFICE HOURS ON THURSDAY, LAST CHANCE FOR QUESTIONS— All these questions have been on an exam 1.

(1 mark) Solow: Says poor countries with the same potential steady-state level of GDP as rich countries will catch up to the rich or poor countries with the same population growth, savings rates and depreciation rates will catch up with rich. This is conditional convergence. (2 marks) The evidence says there is no evidence of unconditional convergence. There is some evidence of conditional convergence if you group countries by geographical regions, same characteristics, etc. The gap is basically staying the same, rather than narrowing. (2 marks) 2.
