8. Factors of production can be: (a) Land (b) Labour (c) Organisation (d) All of the above

In economics, the terms efficient, effective and productive are often known. Question:    a. Explain the difference between each of these terms. Explain with examples    b. How many types of efficiency are there? Explain the difference between each!    c. If the results of the rice production model are as follows:    Qp = 0.031 + 0.046 Land Area + 0.092 Seed + 0.198 TK + 0.728 Fertilizer + 0.222 Perticide. Explain the results of the analysis related to the concept of efficiency for each variable and return of scale

Specify and explain the typical shapes of marginal-benefifit and marginal-cost curves. How are these curves used to determine the optimal allocation of resources to a particular product? If current output is such that marginal cost exceeds marginal benefifit, should more or fewer resources be allocated to this product? Explain.

(a) Suppose that the 149 million square kilometers of land on the surface of the population of 7 billion people in late 2011 or early 2012. population of 7 billion people in late 2011 or early 2012. 4. According to the United Nations Population Fund (UNFPA), the world reached a (a) Suppose that the 149 million square kilometers of land on the surface of the earth was divided equally among this population, so that each person was allotted a square parcel of land How long would the sides of each square parcel be? (b) According to the United Nations Food and Agriculture Organization (FAO), only about 32% of the surface of the earth is considered arable and suitable for farming. If only the arable land was divided into equal square parcels among the population, how long would the sides of each square parcel be? (c) Express your answers to parts (a) and (b) in terms of some concrete unit of length. For instance, you might compare them to the height of the Empire State Building, the span of…
