The world in which we live is complex and to understand it, human beings make use of some orother simplification process. A theory can accordingly be seen as an attempt to simplify things.Such an observation may come as a surprise to those who have often heard remarks to the effectthat such and such a theory is difficult, or at the least terribly complicated. We should neverthelessremind ourselves that a theory involves an attempt to simplify things – it is the world out there thatis the complicated entity. A particular theory (or model) is merely trying to reduce it to manageableproportions, at least as far as understanding our environment is concerned.”In economics, theory is presented in a simple form by making the…1.23a) Post hoc assumptionb) Fallacy of compositionc) Ceteris paribus assumptiond) Blinkered approach

An economy produces two goods ,X and Y .lt uses two means of production, labour and capital. A unit of labour can produce either 1unit of X or 4units of Y (or linear combination of the two).A unit of capital can produce either 4units of X or 1unit of Y (or linear combination of the two)there are 100units of each means of production. (i) Draw the production possibility frontier of the economy when the two goods can only be produced by a mixture of both factors. (ii)What will be the opportunity cost of X if the economy produces 50units of X ? (iii) Given that the production technology is linear ,will the opportunity cost of X remain unchanged when we produce 90units of X ? (iv)Briefly explain the difference between the PPC with a constant opportunity cost and the PPC with an increasing opportunity cost as more output of one good is produced. Use a well labeled diagram to explain your answer?
