Path dependence in energy systems and economic development
Energy systems are subject to strong and long-lived path dependence, owing to technological, infrastructural, institutional and behavioural lock-ins. Yet, with the prospect of providing accessible cheap energy to stimulate economic development and reduce poverty, governments often invest in large engineering projects and subsidy policies. Here, I argue that while these may achieve their objectives, they risk locking their economies onto energy-intensive pathways. Thus, particularly when economies are industrializing, and their energy systems are being transformed and are not yet fully locked-in, policymakers should take care before directing their economies onto energy-intensive pathways that are likely to be detrimental to their long-run prosperity

Low-Income Countries and an SDR-based International Monetary System
The global financial crisis, the weakening role of the dollar and the increasing international importance of China are calling for a reform of the international monetary system in the direction of greater multilateralism. To this end, we advance a proposal based on a greater role of the Special Drawing Rights (SDRs) and focus on the potential benefits that these could bring to Low-Income Countries (LICs). SDRs would be created exogenously - with a disproportionate allocation to LICs -, but also endogenously, through a substitution account and an overdraft facility. Finally, the paper discusses the superiority of this proposal in the context of the current foreign assistance framework
Light scattering of rectangular slot antennas: parallel magnetic vector vs perpendicular electric vector
We study light scattering off rectangular slot nano antennas on a metal film varying incident polarization and incident angle, to examine which field vector of light is more important: electric vector perpendicular to, versus magnetic vector parallel to the long axis of the rectangle. While vector Babinet's principle would prefer magnetic field along the long axis for optimizing slot antenna function, convention and intuition most often refer to the electric field perpendicular to it. Here, we demonstrate experimentally that in accordance with vector Babinet's principle, the incident magnetic vector parallel to the long axis is the dominant component, with the perpendicular incident electric field making a small contribution of the factor of 1/broken vertical bar epsilon broken vertical bar, the reciprocal of the absolute value of the dielectric constant of the metal, owing to the non-perfectness of metals at optical frequencies
