10. Consider the labour/leisure choice problem where the utility function is: U(c,l) = c²l where c is consumption of goods and services, and l is leisure time. The constraint is: w(T – 1) + N = c, where w is the real wage, T is time available for work and leisure and N is income derived from non-labour sources (rents, profits etc). This is all spent on consumption c. (a) Form the Lagrangean, find optimal consumption (c*) and leisure (1*) in terms of w, and N. Do not check the second order conditions. (b) Labour time advanced (L*) is T– l*. Define this in terms of w,T and N. (c) Show that optimal L* change positively as the real wage (w) increases.

Consider the labour/leisure choice problem where the utility function is:
1 1
U(c,l) = czl2,
where c is consumption of goods and services, and l is leisure time.
The constraint is:
w(T – 1) + N = c,
where w is the real wage, T is time available for work and leisure and N is
income derived from non-labour sources (rents, profits etc). This is all spent
on consumption c.
(a)
Form the Lagrangean, find optimal consumption (c*) and leisure (1*) in terms of w, T
and N. Do not check the second order conditions.
(b)
Labour time advanced (L*) is T- 1*. Define this in terms of w,T and N.
(c)
Show that optimal L* change positively as the real wage (w) increases.

A financial instrument promises to pay the following:
After 3 years £10,000
After 7 years £15,000
After 10 years £25,000
Find the net present value of this financial instrument, assuming a
constant interest rate of 2.75% (0.0275).
