Regulating a natural monopoly market has always remained a source of concern. The problem arises because of the decreasing average cost structure in the market. Ideally, only one firm serving the whole market demand is the efficient solution to avoid any cost duplication. However, when there is...

This paper studies the efficacy of entry threats in a contestable environment using experiments. It is hypothesized here that the entrant firm's home market profits influence the entrant's competitive behavior even when entry is costless and completely reversible. In the experiment, entrants and...

I study the effect of sunk entry-costs on potential competition in a multi-market framework, where potential entrants have different home market profits. Although sunk-entry-costs are supposed to increase entry barriers, my experimental results suggest that firms view entry costs differently...
