La economía política de las drogas ilegales en los Andes (Otros Temas)

Este artículo examina el negocio de las drogas ilegales en los Andes desde las relaciones de la oferta y la demanda. Luego, en el intento de construir una respuesta a la interrogante de por qué unos países producen drogas ilegales y otros no, Thoumi cuestiona las cuatro razones (pobreza, desigualdad, crisis económicas y corrupción) que comúnmente se utilizan para explicar este fenómeno, y señala que en muchas ocasiones estas variables son detonantes más que causas. En la parte final, el autor expone las características sociales e institucionales de los países que propician las destrezas necesarias para llevar a cabo actividades ilegales, y argumenta que su solución requiere cambios estructurales en la sociedad.

Technological Solutions Potentially Influencing the Future of Long-Term Care. ENEPRI Research Report No. 114, April 2012

This report provides a forecast of the potential direct and indirect influences of various kinds of technologies on the LTC milieu, answering the following question: from a technology-driven perspective: “Consider each technological solution. What could be its future usage in the LTC sector?” Future technological deployments will induce changes in the respective roles of the care recipient and of the formal and informal carers, with an impact on three major concerns: the transformation of the care recipient into a proactive subject, the augmented potentiality for home care and the new functions that informal carers could assume.

Public and Private Regulation: Mapping the Labyrinth. CEPS Working Document No. 370, October 2012

Private governance is currently being evoked as a viable solution to many public policy goals. However, in some circumstances it has shown to produce more harm than good, and even disastrous consequences as in the case of the financial crisis that is raging in most advanced economies. Although the current track record of private regulatory schemes is mixed, policy guidance documents around the world still require that policy-makers give priority to self- and co-regulation, with little or no additional guidance being given to policymakers to devise when, and under what circumstances, these solutions can prove viable from a public policy perspective. With an array of examples from several policy fields, this paper approaches regulation as a public-private collaborative form and attempts to identify possible policy tools to be applied by public policy-makers to efficiently and effectively approach private governance as a solution, rather than a problem. We propose a six-step theoretical framework and argue that IA techniques should: i) define an integrated framework including both the possibility that private regulation can be used as an alternative or as a complement to public legislation; ii) involve private parties in public IAs in order to define the best strategy or strategies that would ensure achievement of the regulatory objectives; and iii) contemplate the deployment of indicators related to governance and activities of the regulators and their ability to coordinate and solve disputes with other regulators.

The euro crisis: ten roots, but fewer solutions. Bruegel Policy Contribution 2012/17, October 2012

Many factors have contributed to the euro crisis. Some have been addressed by policymakers, even if belatedly, and European Union member states have been willing to improve the functioning of the euro area by agreeing to relinquish national sovereignty in some important areas. However, the most pressing issue threatening the integrity, even the existence, of the euro, has not been addressed: the deepening economic contraction in southern euro-area member states. The common interest lies in preserving the integrity of the euro area and in offering these countries improved prospects. Domestic structural reform and appropriate fiscal consolidation, wage increases and slower fiscal consolidation in economically stronger euro-area countries, a weaker euro exchange rate, debt restructuring and an investment programme should be part of the arsenal. In the medium term, more institutional change will be necessary to complement the planned overhaul of the euro area institutional framework. This will include the deployment of a euro-area economic stabilising tool, managing the overall fiscal stance of the euro area, some form of Eurobonds and measures to make euro-area level decision making bodies more effective and democratically legitimate.

A high-order arbitrarily unstructured finite-volume model of the global atmosphere: tests solving the shallow-water equations

Simulations of the global atmosphere for weather and climate forecasting require fast and accurate solutions and so operational models use high-order finite differences on regular structured grids. This precludes the use of local refinement; techniques allowing local refinement are either expensive (eg. high-order finite element techniques) or have reduced accuracy at changes in resolution (eg. unstructured finite-volume with linear differencing). We present solutions of the shallow-water equations for westerly flow over a mid-latitude mountain from a finite-volume model written using OpenFOAM. A second/third-order accurate differencing scheme is applied on arbitrarily unstructured meshes made up of various shapes and refinement patterns. The results are as accurate as equivalent resolution spectral methods. Using lower order differencing reduces accuracy at a refinement pattern which allows errors from refinement of the mountain to accumulate and reduces the global accuracy over a 15 day simulation. We have therefore introduced a scheme which fits a 2D cubic polynomial approximately on a stencil around each cell. Using this scheme means that refinement of the mountain improves the accuracy after a 15 day simulation. This is a more severe test of local mesh refinement for global simulations than has been presented but a realistic test if these techniques are to be used operationally. These efficient, high-order schemes may make it possible for local mesh refinement to be used by weather and climate forecast models.
