Strengthening cross-border law enforcement cooperation in the EU: the Prüm network of data exchange

The Prüm network was established to provide mechanisms and the infrastructure to achieve a closer cooperation between the EU member states in combating terrorism, organised crime and illegal immigration through the cross border exchange of DNA profiles, fingerprints and vehicle registration data. While Prüm offers clear benefits for cross-border policing, it continues to present challenges of a technical and scientific nature as well as legal, ethical and socioeconomic concerns. This article reviews these challenges as well as the existing safeguards. It argues that, in order to achieve Prüm benefits and maximise its potential, it is important to enhance the necessary dialogue and cooperation between member states so as to confront the above concerns and address challenges posed by Prüm through balanced measures.     

Maintaining Perspective on the Economic Issues of Today

As the new administration takes office it is important to maintain some perspective on the economicchallenges facing the nation. The situation is far better today than when President Obama took office in2009 and 2013. Unemployment is close to pre-Great Recession levels, incomes are rising and poverty ratesfalling. We face economic challenges but the most important ones are not international trade or immigration.Sluggish economic growth, a fiscal crisis in our entitlement programs, high inequality in incomes andwealth, and climate change are what should demand our attention.     

Promises Schmomises

In this piece, I argue that promises need not be kept just because they were made. This is not to say, however, that unwise, unhappy, and unfortunate promises do not generate obligations. When broken promises will result either in wrongful gains to promisors or wrongful losses to promisees, obligations of corrective justice will demand that such promises be kept if their breach cannot be fully repaired. Thus, when a broken promise will constitute a deliberate loss transfer for personal gain, the duty not to exact unjust enrichment (a wrongful gain) will require a promisor either to honor her promise or craft a means of ensuring that the promisee’s impoverishment is not traded for her enrichment. And when a broken promise will constitute the culpable imposition of a reliance-based injury on a nonculpable promisee (a wrongful loss), the duty to make others whole when one has purposefully, knowingly, or recklessly injured them will require one either to keep one’s promise or to fashion a remedy for its breach that ensures that the promisee is left no worse off than he would be had the promise not been made. This account explicitly parts ways with normative powers theories of promising. It places no weight at all on the raw fact that a promise has been made. Instead, it locates the gravamen of a promissory violation in the harm that is caused to a promisee who nonculpably relies upon and changes her position in anticipation of the prediction about the promisor’s future conduct that is embedded in his promise. Absent any adverse reliance on the part of a promisee, there is nothing that gives rise to an obligation of performance or repair on the part of the promisor. But this account is also to be distinguished from utilitarian theories that take promises to be instruments of wealth maximization that properly give way whenever the reason for honoring them speaks in favor of violating them. On my account, the balance of reasons for action that determines the morality of performance includes deontological rights and duties, agent-relative permissions, and Hohfeldian liberties. As I shall argue, even if one rightly concludes that one has no duty either to keep a promise or to craft a remedy for its breach, one must nevertheless remember that virtue requires one to be or become the kind of person who often goes beyond the call of duty. But the fact that virtue often requires us to do what we have no duty to do should not cause us to confuse its conditions with the conditions of right and wrong action. We have a duty to keep promises or to otherwise protect the reliance interests that they generate only when failing to do so will lead either to our own unjust enrichment or to others’ unjust injury. And this means that we have a duty to keep promises in far fewer circumstances than is commonly believed.     

In remembrance of Robert D. Tollison

We discuss the mechanisms related to quadratic voting, from Vickrey’s counter-speculation mechanism and his second-price auction, through the family of Groves mechanisms and its most notable member, the Clarke mechanism, to the expected externality mechanism, Goeree and Zhang’s mechanism, the Groves–Ledyard mechanism, and the Hylland–Zeckhauser mechanism. We show that each mechanism that involves collective decisions has a quadratic aspect and that all of the mechanisms that we discuss are applications of the fundamental insight that for a process to be efficient, all parties involved must bear the marginal social costs of their actions.

Relating Seasonal Hunger and Prevention and Coping Strategies: A Panel Analysis of Malawian Farm Households

Relative to chronic hunger, seasonal hunger in rural and urban areas of Africa is poorly understood. This paper examines the extent and potential correlates of seasonal hunger in Malawi using panel data from 2011–2013. We find that both urban and rural households report seasonal hunger in the pre-harvest months. Certain strategies to smooth consumption, including crop storage and livestock ownership, are associated with fewer months of hunger. In addition, we find that Malawian households that experience seasonal hunger harvest their crops earlier than average – a short-term coping mechanism that can reduce the crop’s yield and nutritional value, possibly perpetuating hunger.
