The Spanish Pension System: Overview and Long-Term Projections

In the middle of the so-called pension crisis, the ageing of population and the sharp decrease in affiliations to Social Security are threatening the well-functioning of the Spanish public pension system. The purpose of this paper is to present the main challenges to be faced by the Spanish pension system, as well as to shed light on the main determinants that will condition the evolution of pension expenditure over GDP along the following decades. This quantitative analysis, which considers the 2011 and 2013 pension reforms, uses the latest data on the Spanish demographic, labor market and institutional factors in order to project the evolution of the system from the expenditure side up to 2060. For the purpose of analyzing the dynamics and the underlying drivers of pension expenditure, the so-called aggregate accounting approach will be utilized. The alternative scenarios proposed allow for exploring the robustness of the results within the baseline scenario, which constitutes the reference point of projections in the exercise. The analysis concludes that, by the end of the projected period, Spain will count on a similar public pension expenditure ratio as the current one.

Transmission network expansion planning for the Colombian electrical system: Connecting the Ituango hydroelectric power plant

The hydroelectric power plant Hidroltuango represents a major expansion for the Colombian electrical system (with a total capacity of 2400 MW). This paper analyzes the possible interconnections and investments involved in connecting Hidroltuango, in order to strengthen the Colombian national transmission system. A Mixed Binary Linear Programming (MBLP) model was used to solve the Multistage Transmission Network Expansion Planning (MTEP) problem of the Colombian electrical system, taking the N-1 safety criterion into account. The N-1 safety criterion indicates that the transmission system must be expanded so that the system will continue to operate properly if an outage in a system element (within a pre-defined set of contingencies) occurs. The use of a MBLP model guaranteed the convergence with existing classical optimization methods and the optimal solution for the MTEP using commercial solvers. Multiple scenarios for generation and demand were used to consider uncertainties within these parameters. The model was implemented using the algebraic modeling language AMPL and solved using the commercial solver CPLEX. The proposed model was then applied to the Colombian electrical system using the planning horizon of 2018-2025. (C) 2014 Elsevier B.V. All rights reserved.

Retos y alternativas de inversión para las compañías aseguradoras en Colombia

En este documento se explica el rol de las compañías aseguradoras colombianas dentro del sistema pensional y se busca, a través de la comprensión de la evolución del entorno macroeconómico y del marco regulatorio, identificar los retos que enfrentan. Los retos explicados en el documento son tres: el reto de la rentabilidad, el reto que plantean los cambios relativamente frecuentes de la regulación, y el reto del “calce”. El documento se enfoca principalmente en el reto de la rentabilidad y desarrolla un ejercicio de frontera eficiente que utiliza retornos esperados calculados a partir de la metodología de Damodaran (2012). Los resultados del ejercicio soportan la idea de que en efecto los retornos esperados serán menores para cualquier nivel de riesgo y sugiere que ante tal panorama, la relajación de las restricciones impuestas por el Régimen de inversiones podría alivianar los preocupaciones de las compañías aseguradoras en esta materia. Para los otros dos retos también se sugieren alternativas: el Algorithmic Trading para el caso del reto que impone los cambios en la regulación, y las Asociaciones Público-Privadas para abordar el reto del “calce”.

The Impact of New Capital Requirements on the Portfolio Decisions of Finnish Pension Institutions

This paper examines the potential impact of new capital requirements on asset allocations of Finnish pension institutions. We describe the new requirements and consider portfolio construction to minimize regulatory capital, given the investor’s preferred level of expected return. Results identify portfolio transactions that enhance expected return without increasing capital needs. Regulation calls for portfolio diversification and prudence in management, but this paper shows that market participants can exploit inconsistencies in regulation. Possible future consequences include capital outflows from the pension system and an unintended decrease in pre-funding of old-age pensions.

Swedish Premium Pension Funds: Attributes and Performance

This study investigates the relationship between fund attributes and performance. The focus is on funds available in the Swedish Premium Pension system (PPM-funds). The aim has been to investigate whether administration fees, manager tenure or past performance are of importance for pension savers when they pick their PPM-funds. The results indicate that high fees are a disadvantage to pension savers investing in bond funds but not to those investing in stock funds. Manager tenure has no relationship with performance. There is evidence of performance persistency in most of the investigated fund categories.

Pension structural reforms, re-reforms and their effects on social welfare: The case of Chile

This article fi rst summarizes the structural reforms of pensions (total or partial privatization) in Latin America and Central and Eastern Europe, identifying their advantages and disadvantages, and does the same with the international process of re-reforms of pensions with a greater role of the state. Second, chooses Chile as a case study, as a world pioneer in both types of reforms; describes their characteristics and effects on social welfare of the structural reform of 1981 and the re-reform of 2008. Such effects are evaluated based on ten basic principles of social security from the International Labour Offi ce (ILO): 1) social dialogue to approve the reforms, 2) universal coverage of the population, 3) equal treatment of insured persons, 4) social solidarity, 5) gender equity, 6) suffi ciency of benefi ts, 7) effi ciency and reasonable administrative cost, 8) social participation in the management of the system, 9) role of the state and supervision, and 10) fi nancial sustainability. Third, it summarizes the advantages and disadvantages-challenges of the re-reform and informs on the current debate for further reforms.

Efectos del sistema de multifondos en el Régimen de Ahorro Individual en Colombia

Recientemente, el gobierno nacional radicó un proyecto de reforma financiera en el que se propone flexibilizar la regulación de los Fondos de Pensiones. En particular, se propone que los agentes pueden escoger la composición del portafolio en el que están invertidos sus ahorros pensionales. Para evaluar los posibles efectos de este cambio sobre el bienestar de los agentes, este trabajo analiza las decisiones de inversión de un individuo con función de utilidad con aversión absoluta al riesgo constante (CARA) frente a la Teoría de la diversificación del portafolio. Adicionalmente, se realiza un ejercicio contrafactual con el fin de calcular cual hubiera sido el valor del activo pensional para diferentes individuos si la legislación propuesta por el gobierno hubiera aplicado para el período 1980-2008. Este ejercicio se realiza utilizando información de las Bolsas de Valores de Colombia y la Encuesta de Calidad de Vida 2003 (ECV 2003), siguiendo la metodología de Herscovich (2003) los resultados del análisis teórico sugieren que ante un mayor valor acumulado en las cuentas de pensión, los individuos disminuyen su exposición ante el riesgo en sus portafolios. Así, la composición del portafolio debe estar más concentrada en renta variable para los agentes jóvenes y más concentrada en renta fija para los agentes viejos. Por otro lado, el ejercicio contrafactual, indica que la mejor decisión habría sido invertir todo el portafolio en activos de renta variable. Este contraste en los resultados llama la atención acerca de dos problemas: Primero, es posible que la estrategia que maximiza la utilidad ex-ante de los individuos no sea la misma que maximiza el valor de su pensión. Segundo, el ejercicio presentado parte del supuesto de que no hay información adicional que permita suponer cambios de tendencia o de volatilidad en las rentabilidades de los distintos activos financieros. No obstante, es claro que los especialistas en el mercado financiero cuentan con información suficiente para predecir este tipo de eventos. Por esta razón, el estudio sugiere que el papel de la asesoría financiera a los ahorradores es fundamental para permitir un cambio al sistema multifondos, puesto que el incremento en las opciones de inversión no conduce a un incremento en el bienestar de los individuos en ausencia de información. Adicionalmente, al comparar la evolución de las cuentas de pensión con los porcentajes históricos y con el sistema multifondos, se encuentra un mejor desempeño cuando el porcentaje de inversión en activos de renta variable es mayor que el actual, lo cual sugiere un incremento en la restricción actual de inversión de activos de renta variable para mejorar el desempeño de los fondos.

Equilibrium Principle in Colombian Public Contracting

Public contracting in Colombia is conflicting and inefficient. It frequently leads to damage to State property. The Colombian legal system cannot assure efficient and transparent public contracting. The cause is the institutional environment characterized by high transaction costs. Colombian law worsens the process by recognizing the principle of economic equilibrium in public contracts. This principle increasese contract incompleteness and renders impossible the use of economic incentives to control the opportunism of the economic agents. The authors present the hypothesis that the economic equilibrium principle increases the conflictive nature of public contracting. They test the hypothesis empirically. The first section of the paper presents a summary of the literature on transaction costs economics, as well as the legal literature on the historical origin and the content of the economic equilibrium principle. The second section describes the methodology of the empirical study. The third section shows the empirical evidence of the effects that the economic equilibrium principle exerts over the public contracting. The last section presents the conclusions.
