The monopolist faces a demand curve given by Q (p) = 50−2.5p. Its cost function is C(y) = 4y. What is its optimal level of output and price?
Global warming has had significant negative effects. But it has also had some positive effects. ln particular, wine-growing regions in several major producing countries have expanded, increasing the overall world supply of wine. But the demand for wine has also increased over this period. Use supply and demand curves to show what happens to price and quantity as a result of these two developments.

As a result of imbalance in revenue generation by provincial governments and local municipalities in South Africa, intergovernmental grants have been a important source of finance for Local Governments. The allocations of these funds for use in the local authorities have been questionable, some doubting if the funds are use for what they were earmarked for. Critically discuss, with the aid of diagrams the conditional no -matching grants with unconditional nonmatching grant?
