Using a Cournot oligopoly model with an endogenous number of firms and evasion of indirect taxes, this paper shows that … more intense competition may have the negative side-effect of eroding tax revenues by increasing tax evasion. This will be … weakly concave or convex and inelastic. The desirable result of more competition, less evasion and higher tax revenues will …

Unlike standard auctions, we show that competitive procurement may optimally limit competition or use inefficient … auction to guard against firms bidding low to win the contract and then cutting back on effort. While competition helps reduce …

We modify the paper of Stahl (1989) on sequential consumer search in an oligopoly context by relaxing the assumption …
