This paper looks at how keeping investment costs hidden can impact investment decisions in a competitive market. If the first mover benefits more from investing than the second mover, there is a specific balanced outcome. However, if the second mover gains more, there is a different balanced outcome. When profit uncertainty is high and investment costs are uncertain, sharing information leads to higher benefits for the first mover. But when both profit volatility and investment cost uncertainty are low, sharing information benefits the second mover.
