Hard Core Cartels aim to design, being aware of the presence of an antitrust authority, market practices granting avoidance of antitrust investigations. We show, in a dynamic game, that they can reach this goal and get extra—normal profits. However, the bulk of this opportunity does not lay,...

We consider vertical price restrictions like Recommended Retail Prices (RRP) and Resale Price Maintenance (RPM), together with a retailer’s unit discount when purchasing the good from the manufacturer. We study how retailer’s buyer power affects the nature of the vertical price restriction...

This paper presents a new stochastic frontier model for panel data. The model takes into account firm unobservable heterogeneity and short-run and long-run sources of inefficiency. Each of these features is modeled by a specific random effect. In this way, firms’ latent heterogeneity is not...

This paper investigates the process of GDP generation in Former Soviet Union (FSU) economies to provide understanding of the impact of technology channels on countries’ efficiency. We apply a stochastic frontier approach to 15 FSU economies over the period 1995–2008, and we find that...

Policy makers have made several attempts to limit hospitals upcoding. We investigate the impact on discharges with and without complications of a law introducing a minimum length of stay to discharges with complications. We implement a DID econometric model to assess the impact of the law and a...

We investigate how the intensity of competition among airports affects their technical efficiency by computing airports’ markets on the basis of a potential demand approach. We find that the intensity of competition has a negative impact on airports’ efficiency in Italy during the...

A wider RJV extension hastens process innovations at the cost of increasing collusion in the .nal market. In a Cournot model, an extended RJV is welfare enhancing only when the Antitrust Authority is strong, so that the increase in distortion is limited, and when the size of the technical...

This paper investigates the efficiency of Italian hospitals during the period 1998–2007 and consider the impact of some DRG distortions like uocoding, cream skimming and readmission. We apply both a stochastic frontier approach and a multilevel model. We show that readmissions are the most...

In this paper we study the efficiency of European airports by applying a DEA model to 57 airports. The sample covers 95% of all the airports with a traffic of at least 5 millions passengers (yearly). We find that largest airports (with more than 10 millions passengers) are more efficient, while...

We develop a dynamic duopoly, where .rms have to take into account a technological externality, that reduces over time their innovation costs, and an inter-.rm spillover, that lowers only the second comer.s R&D cost. This spillover exerts its e¤ect after a disclosure lag. We identify three...
