Answer: shift to the left
Step-by-step explanation:
The social return helps in comparing the value of benefits and the costs to achieving the benefits. The social return is the ratio of net present value of the benefits in comparison to the net present value of the investment or the costs to getting the benefits.
In this case, if a small electric automobile manufacturer is able to gain the social return generated by its electric motor, it would decrease the demand for financial capital which simply means that the demand for financial capital will shift to the left. This shift to the left is as a result of the gain in its social return gotten by the electric motor.
