(1) Leo has utility function U=log(cl) where c= consumption, l= leisure. There are 168 hours per week to be divided between leisure and work. The hourly wage rate is 100. Write down his budget constraint and graph it. [25] What are his optimal levels of consumption and leisure? [25] Where a worker has non-labour income m and faces a wage rate w, use a diagram to illustrate how his reservation wage would be determined. [25] Show how his reservation wage changes if there are hours restrictions such that, if he works, he must work at least h hours per week [25]
