This is an extract of our Pareto Optimality Mathematical Methods & Model Analysis document, which we sell as part of our Advanced Microeconomics Notes collection written by the top tier of University Of Leeds students.

The following is a more accessble plain text extract of the PDF sample above, taken from our Advanced Microeconomics Notes. Due to the challenges of extracting text from PDFs, it will have odd formatting:

PARETO OPTIMALITY ANSWER An economy is composed of consumers with identical incomes and an identical utility function U=x1 0.5x20.5. There is a single input labour, of which 100 units are available. Production of x 1 requires 2 units of labour per unit of output; production of x2 requires 3. (i) Find an expression for the slope of the set of indifference curves of the consumers MRS = -
