Does policing help in reducing crime rates?
Those studies trying to assess the impact of policing on crime which are based on police-recorded crime figures often report a negative effect of police on property crime but no effect of police on violent crime. In a recent
the effect of police on violent crime. They do not find a similar estimation bias for the effect of police on property crime. Changes in the way the police record violent incidents rather than changes in reporting behavior of the public are shown to be the underlying cause of the estimation bias. This type of measurement error in police-recorded crime has been found in many countries, including the US. To address the classical chicken-and-egg problem in the relation between police and crime, the authors model the police funding formula which is used to distribute police resources across police force areas in England and Wales. By using the difference between actual police levels and police levels predicted by the funding formula, they can identify the real effect of police on crime.
Can exclusionary long-term contracts be justified?
In spite of the Chicago school arguments, it is well known that in certain cases an incumbent firm may use exclusivity contracts so as to monopolize an industry or deter entry. Such an anticompetitive practice could be tolerated if it were associated with sufficiently large efficiency gains, e.g. insuring buyers against price volatility, a rationale that is often invoked to justify long-term contracts in the energy sector. In a recent TILEC discussion paper, TILEC members Cédric Argenton and Bert Willems study the trade-off between the positive effects (risk sharing) and the negative effects (exclusion) of exclusivity contracts. The authors revisit one of the main 'theories of harm' under risk-aversion and show that although exclusivity contracts induce optimal risk-sharing, they can be used not only to deter the entry of a more efficient rival on the product market, but also to crowd out financial investors willing to insure buyers at competitive rates. They further show that in a world without financial investors, purely financial bilateral instruments, such as forward contracts, achieve optimal risk sharing without distorting product market outcomes. Thus, they argue there is no room for an insurance defense of exclusivity contracts.
Energy investment; a balancing exercise

Paradoxically, State aid is, in principle, prohibited by European competition law unless it contributes to clearly defined objectives of common interest, such as environmental protection or security of supply. State aid must therefore be notified to the Commission in order to be assessed for exemption from the State aid prohibition. The need to balance different objectives in the State aid assessment leaves Member States with great uncertainty about how to design their State aid measures to get Commission's clearance. In her recent discussion paper, TILEC member Natalia Fiedziuk tries to clarify the approach of the European Commission to State funding of energy infrastructure, and in particular what significance it attaches to different objectives of the European energy policy in the final decision making. One of the conclusions of the paper is that the leniency of the European Commission vis-à-vis State funding of energy infrastructure will depend on the extent the infrastructural project delivers priority objectives of common interest set in the European energy policy.
