The paper extends the Salop model of localized competition by allowing firms to have heterogeneous costs. We provide a general but highly tractable analytical solution for the equilibrium prices, and we study the long-run properties of the model using two different entry games. We show that cost...

Using more than 10 million on-line fares, we study the determinants of yearly fares' changes in June 2002-June 2005. We verify whether airlines took advantage, after the Euro introduction, of potential inflationary pressures by increasing their fares more in routes to Eurozone nations. The...

We analyze the entry and exit activity in the European Airline Markets in the post-liberalisation period and study the differential traits between traditional and low cost carriers. Alongside with the characteristics traditionally highlighted as determinants of entry (such as airport presence...

This study uses firm level data from two detailed surveys of Italian manufacturing firms to study the relationship between R&D expenditures and productivity growth. The analysis considers the different contributions of various forms of R&D (product, process, internal, external in collaboration...

Three forces affect the pricing of a firm's inventory over time, if it can sell multiple units before any price adjustment takes place. Perishability drives prices down; scarcity and intertemporal price discrimination up. Hidden prices arise because all items, even if not immediately up for...

This study explicitly takes into account that the decision to enter into a cooperative R&D relationship is related to the antecedent decision to carry out R&D. This calls for a methodological approach that, at the same time, allows the joint analysis of the determinants of the two decisions and...
