Question

provide at least 4 cases that shifts the iso cost line and create new producerequulibrium point

Answer 1

Isocost line represent all the combinations of inputs which costs the same total amount. Its the firm's budget constraint when buying factors of production. Producer is in equilibrium when isocost line is tangent to the highest isoquant. Therefor, Shift of isocost line implies a change in producer equilibrium.

Now let's look at 4 cases that shifts the isocost line and create new producer equilibrium point.
