**What is the least cost combination?** The principle of least cost combination states that if two factor inputs are considered for a given output the least cost combination will be such where **their inverse price ratio is equal to their marginal rate of substitution**.

## What are the technical conditions of optimal combinations of inputs?

The first order conditions state that the variable factors are combined in an optimal manner when the ratio of marginal products is equal to the ratio of factor prices. This optimal combination is called the **least cost combination of inputs**.

## When total product is highest marginal product will be?

Relationship between Marginal Product and Total Product

It states that when only one variable factor input is allowed to increase and all other inputs are kept constant, the following can be observed: When the Marginal Product (MP) increases, the Total Product is also **increasing at an increasing rate**.

## What is Isoquant curve?

An isoquant curve is **a concave line plotted on a graph**, showing all of the various combinations of two inputs that result in the same amount of output. Most typically, an isoquant shows combinations of capital and labor and the technological trade-off between the two.

## What does W and R mean in economics?

w/r is the **wage rate to rental rate** (the cost of employing capital as an input) ratio. This measures the relative cost of employing inputs.

## What is optimal input level?

It is another application of the maximization principle, which says that the best level of an input is that **level for which its marginal benefit to the firm–the extra money the firm can obtain by hiring or buying the input**–just equals the marginal cost to the firm of hiring or buying the input.

## What is isoquant curve?

An isoquant curve is **a concave line plotted on a graph**, showing all of the various combinations of two inputs that result in the same amount of output. Most typically, an isoquant shows combinations of capital and labor and the technological trade-off between the two.

## What is expansion path in economics?

In economics, an expansion path (also called a scale line) is **a path connecting optimal input combinations as the scale of production expands**. … As a producer’s level of output increases, the firm moves from one of these tangency points to the next; the curve joining the tangency points is called the expansion path.

## When total product is increasing at an increasing rate marginal product is?

If the total product curve rises at an increasing rate, the marginal product of **labor curve is positive and rising**. If the total product curve rises at a decreasing rate, the marginal product of labor curve is positive and falling. 8.

## When total product is increasing at a decreasing rate marginal product is?

Marginal product is the additional output produced by one additional unit of variable input in the short run. The Marginal product diminishes with the **increase in the level of production**.

## When marginal product is zero the total product is?

When the marginal product is zero then **the total product becomes constant at its maximum**. With the increase in product , the total variable costs also increase but at a lesser rate . With a decreasing marginal product, the total variable cost increases at an increasing rate.

## Why can’t two Isoquants cross?

Therefore, isoquants cannot intersect. An isoquant must always be convex to the origin. This is because of the operation of **the principle of diminishing marginal rate of technical substitution**. … The MRTS diminishes because the two factors are not perfect substitutes.

## What are the types of isoquant curve?

**Linear Iso-quant Curve**: This curve shows the perfect substitutability between the factors of production. Right Angle Iso-quant Curve: This is one of the types of iso-quant curves, where there is a strict complementarity with no substitution between the factors of production. …

## What is equal product curve?

Equal product curve is also known as **production indifference curves**. A given quantity of output that can be produced with different combination of inputs are shown by the isoquant. Isoquant curves are also called as Equal product, Isoproduct or Production Indifference curves.

## What does p * mean in economics?

This P is referred to as the **market price** P*, since it is the price where quantity supplied is equal to quantity demanded. To find the market quantity Q*, simply plug the equilibrium price back into either the supply or demand equation.

## What is the full form of economics?

**Rating**. **ECONOMICS**. **Excellent Conception Of Normal Or Maniacal Incidents** Conditioning Society.

## How do you find the optimal level of input?

Profit = TVP – TC = TVP –TVC – TFC = Py. **Y – Px X – TFC**. The criterion for determining the optimum amount of input is derived from the slopes of total value product and total cost curves, when those curves are plotted as functions of the input, X.

## How is the most profitable amount of input determined?

Profit is maximized at the **level of variable input where the MVP = MIC**, that is, where the value of the additional output produced by using one more unit of variable input is equal to the cost of that last unit of variable input.

## What is the optimal level of output?

The optimal output, shown in the graph as Q_{m}, is **the level of output at which marginal cost equals marginal revenue**. The price that induces that quantity of output is the height of the demand curve at that quantity (denoted P_{m}).

## How do you calculate expansion path?

For any input prices, the firm uses y/a units of input 1 and y/b units of input 2 to produce y units of output (see its conditional input demands), so that its output expansion path is the **line z _{2} = (a/b)z_{1}.**

## How do you calculate income expansion path?

The income expansion path (also called income consumption curve, IEP) is a graph that shows how different income affects consumption of two different products. To find the income expansion path, **you find the consumer’s optimum of each budget constraint and draw a curve to connect the consumer’s optimums together.**

## How can you drive an expansion path of a firm?

First, it may want to expand by successively increasing its level of cost or its expenditure on the inputs X and Y, i.e., by using more and more of inputs, and, consequently, by producing more of its output. Second, the firm may decide to expand **by increasing its level of output per period**.

## When total product is increasing at a increasing rate?

**When the marginal product is increasing**, the total product increases at an increasing rate. If a business is going to produce, they would not want to produce when marginal product is increasing, since by adding an additional worker the cost per unit of output would be declining.

## What is marginal cost equal to?

Marginal Cost is equal to **the Change in Total Cost divided by the Change in Quantity**. Marginal Cost refers to the cost required produce one more unit of Q. Marginal Cost is equal to the Wage Rate (Price of Labor) divided by the Marginal Productivity of Labor.

## Why does marginal cost Finally increase?

Marginal Cost. Marginal Cost is the increase **in cost caused by producing one more unit of the good**. … At this stage, due to economies of scale and the Law of Diminishing Returns, Marginal Cost falls till it becomes minimum. Then as output rises, the marginal cost increases.
