Deflating Russia’s gas pressure

The contest between the EU and Russia over their neighbourhood has intensified. The future of Ukraine is the coveted prize. Moscow is determined to thwart Ukraine’s drift towards the EU. Yet, even as Moscow still holds many cards, the EU is well positioned to counteract Russian pressure head on.

On the global supply of basic research

&
In this paper we study the incentives for basic-research investments by governments in a globalized world. For this purpose, we develop a two-country Schumpeterian growth model in which each country chooses its basic-research investments. We find that a country’s basic-research investments increase with the country’s level of human capital and decline with its ownmarket size. This may explain the large basic-research investments by small open economies. Compared with the optimal investments achievable when countries coordinate...

Measurement of the “Underlying energy efficiency” in Chinese provinces

&
China is one of the largest consumers of energy globally. The country also emits some of the highest levels of CO2 globally. In 2009, 18% of the world’s total energy was consumed in China and the growth rate of energy consumption in China is 6.4% per year. In recent years, the Chinese government decided to introduce several energy policy instruments to promote energy efficiency. For instance, reduction targets for the level of energy intensity have...

Complements and substitutes in generalized multisided assignment economies

We consider a finitely populated economy in which there are different types of agent, each agent is of exactly one type, and profit is created by coalitions containing at most one agent of each type (or side). The surplus of a so-called generalized multisided assignment economy is defined as the maximum aggregate profit that can be attained by matching agents into pairwise disjoint coalitions of the above kind. We present negative results that establish that...

A robust approach to risk aversion

&
We investigate whether the set of Kreps and Porteus (1978) preferences include classes of preferences that are stationary, monotonic and well-ordered in terms of risk aversion. We prove that the class of preferences introduced by Hansen and Sargent(1995) in their robustness analysis is the only one that fulfills these properties. The paper therefore suggests a shift from the traditional approach to studying the role ofrisk aversion in recursive problems. We also provide applications, in which...

The One-Time Pad Revisited

&
The one-time pad, the mother of all encryption schemes, is well known to be information-theoretically secure, in contrast to most encryption schemes used in practice, which are at most computationally secure. In this paper, we focus on another, completely different aspect in which the one-time pad is superior to normal encryption, and which surfaces only when the receiver (not only the eavesdropper) is considered potentially dishonest, as can be the case in a larger protocol...
