Inventors in developing countries are usually unable to capture the full benefit of their innovations. They therefore tend to devote too few resources to research. Government can address this problem of under-investment in research by (i) increasing restrictions on trade; (ii) establishing a patent system to provide inventors with exclusive control over their inventions for a period of time; (iii) subsidising the purchase of technology from other countries. a. only (i) is used.
b. only (ii) is used.
c. only (iii) is used.
d. (i), (ii) and (iii) are all used.

You own a nonunion company with 93 nonexempt employees. all of these employ- ees pack books into boxes for shipment to customers throughout the united states. because of wide differences in performance, you have decided to try performance appraisal, something never done before. until now, you have given every worker the same size increase. now you want to measure performance and reward the best performers with bigger increases. without any further information, which of the five types of appraisal formats do you think would be most appropriate? justify your answer. do you anticipate any complaints, or other comments, from employees after you implement your new system?
