4. if there is a technology breakthrough is improved, does it mean the supply will increase?

i think is no.

If the supply of good A increase, then the competitive supply of good A will drop.

Just think

.......

If the increased supply can induce a increase in revenue
then the supply will increase
so all depends on the elasticity of demand
the answer is no (not sure)

我就覺得第4題因為有technology breakthrough, cost of production is reduced,
假設, 用黎produce果筆錢不變的話, supply咪多左囉

的確有potential 去increase supply
但若果demand 係inelastic
increased supply 所帶黎o既decrease in price 只會做成損失
supply curve 係the quantity supply that the firm is willing and able to produce at each price level

注意able to produce 並不代表willing to produce

我假設左elasticity of demand 係 1丫嘛 (holding other things being constant)
