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...

Common wisdom suggests that entry reduces profits of the incumbentfirms. On the contrary, we show that if the incumbents differ in marginal costs and theentrants behave like Stackelberg followers, entry may benefit the incumbents who arerelatively cost efficient while it always hurts the cost...

This paper re-considers the comparison of Bertrand and Cournot equilibria in a differentiatedduopoly with linear demand and cost functions. It focuses on the case of substitutegoods, and allows for cost asymmetries between firms. The main finding is that, when thedegree of cost asymmetry is...

In this paper we consider a regulated monopoly that can pad its costs to increaseits cost reimbursement. Even while padding is ineácient the optimal incentivescheme tolerates some padding of costs to reduce the information rents paid tolow cost types. It is shown that high cost ßrms pad costs...

In this paper, we aim to model the vertical relation between retailers and suppliersin the food industry whereby retailers exercise seller power in their relation with consumersand buyer power in their relation with producers. We then evaluate the degree of pricetransmission, relative to the...

This paper is concerned with the impact of food scares, principally the BSE crisis, in the UK and focuses on price adjustment at different stages in a vertically-related market. Our interest is motivated primarily by the presence of market power that is alleged to occur in UK food retailing....

This paper focuses on price transmission in a vertically-related set-up where the retail stage may exercise oligopoly and/or oligopsony power, an issue addressed by the UK anti-trust authority investigation of the food retailing sector. From a theoretical perspective, we set out simple tests...

This paper is concerned with the impact of food scares, principally the BSE crisis, in the UK and focuses on price adjustment at different stages in a vertically-related market. From a theoretical perspective we show that if market power has an effect on the margin between retail and farm prices...

In open-end funds, net inflows are positively correlated with past performance. This study investigates how past net asset value (NAV) returns affect the premium on closed-end funds traded in the United States and the United Kingdom. Past performance is significantly priced in stock funds,...

...In this paper, we tackle all these difficulties by conducting a full geomatrical analysis of the comparative statics of general models...
