Clearly distinguish between the following pairs of concepts as used ina economics.

a)production possibility set and input requirement set
b)price discrimination and multi plant monopolist.
c)partial equilibriam and general equilibrium analysis

a) Production possibility set and input requirement set:

- Production possibility set (also known as production possibility frontier) refers to the combination of goods and services that can be produced given available resources and technology. It represents the maximum output an economy can produce using all its resources efficiently.
- Input requirement set, on the other hand, refers to the combination of inputs (such as labor, capital, raw materials) needed to produce a given level of output. It represents the minimum inputs required to produce a specific level of output efficiently.

To understand these concepts, you can consider the following steps:
1. Identify the resources and technology available in an economy.
2. Determine the maximum combination of goods and services that can be produced efficiently using all available resources and technology. This represents the production possibility set.
3. Analyze the specific inputs required to produce a given level of output. This represents the input requirement set.

b) Price discrimination and multi-plant monopolist:
- Price discrimination refers to the practice of charging different prices to different customers for the same product or service. It occurs when a seller can segment the market and identify different price elasticities of demand among buyer groups.
- A multi-plant monopolist, on the other hand, refers to a monopolistic firm that operates multiple production plants. Each plant is located in a different region, allowing the firm to serve different markets with differentiated prices.

To understand these concepts, you can follow these steps:
1. Understand the concept of monopolistic firms that have control over the market.
2. Analyze the pricing strategies of such firms. If the firm charges different prices based on customer groups or regions, it indicates price discrimination.
3. In the case of a multi-plant monopolist, identify how the firm operates multiple plants to serve different markets. This often involves different prices for each market served.

c) Partial equilibrium and general equilibrium analysis:
- Partial equilibrium analysis focuses on the analysis of a specific market, assuming all other markets remain unchanged. It examines the interactions between demand and supply within a particular market.
- General equilibrium analysis, on the other hand, considers the interdependences between multiple markets in an economy. It analyzes how changes in one market affect other markets and the overall equilibrium of the economy.

To understand these concepts, you can follow these steps:
1. Identify the market or markets under analysis.
2. Conduct a partial equilibrium analysis by focusing on the interactions between demand and supply within the selected market.
3. To conduct a general equilibrium analysis, consider the interactions and interdependences between multiple markets. Assess how changes in one market can spill over and affect other markets in the economy.
