This paper examines the stock market reaction to annual earnings information releases using data on the Nigerian Stock Exchange. Using the event study method, the speed of reaction of the market to annual earnings information releases for a sample of 16 firms listed on the exchange is tested....

We provide a theoretical justification for bi-sourcing, which refers to thesituation where a final goods producer buys an input from an outside supplier and alsoproduces it in-house. Bi-sourcing occurs if the marginal cost of producing the input inhouseis higher than the marginal cost of outside...

We examine a Stackelberg game where a financially constrainedleader faces competition from a ‘deep pocket’ follower. We analyzethe consequences of this trade-off between a financial and a strategicadvantage for both the design of financial contracts and market structure.We derive conditions...

We show the effects of Bertrand and Cournot competition on R&D investmentand social welfare in a duopoly with R&D competition where success in R&D isprobabilistic. We show that R&D investments are higher under Bertrand (Cournot)competition when R&D productivities are sufficiently low (high), and...

If households and firms face different interest rates, there may be mutual gains in forming seniority wage contracts, which facilitate implicit saving by younger workers, who might otherwise save either little or nothing at all at low interest rates. A three-period OLG model is presented with...

We show the welfare effects of entry in presence of technology licensingunder Cournot competition. If the entrant is technologically inferior to that of theincumbent then, though licensing reduces (or completely eliminates) excessive entryfor relatively low entry costs, it creates excessive...

We consider the effects of an imperfectly competitive banking sector on the capital stock in a version of the two-period Diamond OLG model, focusing on how profits are returned. There are two broad alternatives: profits may be taxed and returned to households exogenously as fiscal transfers or...
