Expert Solution
Step 1: What is technological improvement and and productivity

Technological improvement is improvement in the efficiency of the production system that means producers are producing goods by using less amount of inputs. Now we come to the term productivity. Productivity actually leads the production of goods and services. Now both of them are related. If technological improvements are there then production increases as well as demand also increases because the cost of production is low that price is lower than other products.
