Clearly there's no change in the equilibrium price, exit threshold or entry/exist rate but the measure of entrants is increased from 0.08 to 0.096. Average firm size also increases to 78.67 with an elevated aggregate firm profit.
The reason that the demand increase has such an impact is that given the labor as a numeraire and taking price and wage rate as given, incumbents would employ more labor and increase output, hence increases the expected payoff of the entrants and attracts more entrants until free entry condition rebinds. It's also computationally clear as the process of determining equilibrium price has nothing related to the demand. This also explains why a larger measure of entrants is seen.
