Administrative authorization for the demolition of urban rental units pursuant to the law of 1964: a spanish example of problematic over-activity in the application of transitional laws

Transitional provisions are defined as the set of regulations that rule juridical relationships on the occasion of a legislative change. Out of this context of law succession, their indiscriminate application can lead to serious inconsistencies. The analysis of a Spanish private law example is offered to illustrate this fact. It concerns the administrative authorization for the demolition of rented buildings in the cities. A regulation repealed more than fifteen years ago and however widespread utilised on ancient constructions that, after recent urban development, have acquired great economic value; something that in the end explains the current importance of such provisions. What is happening in Spain: denaturalization of the original  figure due to a mixture of formalist interpretations and speculative market interests, is presented here to call the attention on the necessary limitation of transitional provisions’ effects.

Testing the law of one price in food markets: evidence for Colombia using disaggregated data

This paper applies stationarity tests to examine evidence of market integration for a relatively large sample of food products in Colombia. We Önd little support for market integration when using the univariate KPSS tests for stationarity. However, within a panel context and after allowing for cross sectional dependence, the Hadri tests provide much more evidence supporting the view that food markets are integrated or, in other words, that the law of one price holds for most products.

Do more decentralized local governments do better? an evaluation of the 2001 decentralization reform in Colombia

In this paper I evaluate the impact of the 2001 decentralization reform in Colombia. I use data from Colombia's municipalities. I look at the effect of the 2001 reform on enrolment in pre-college schools. While all municipalities received earnmarked national transfers, withthe reform some of then now have more responsabilities to provide education (deeper decen-tralization) than others. Particulary important, the reform entitle the more decentralizedmunicipalities to sign subsidy contracts with private school. Departments (the regional gov-ernments) are entitle to sign this type of contracts for the less decentralized municipalities.Since the rule for municipalities to receive more responsabilities follows and exogenous popu-lation threshold, I can implement Regression Discontinuity Design. Enrolment is measuredthrough two variables: the number of students enroled in public schools and the number of subsidized students enroled in private schools. Results sugest that more decentralized mu-nicipalities subsidize more students in private schools. The difference is significant at all thelevels of pre-college school for the period 2004-2006. In 2005, the difference accounts for20% of enrolment in private schools and 3% of population of school age. Besides, there are not significant differences among municipalities regarding enrolment in public schools.

Performance and efficiency in Colombia's power utilities: an assessment of the 1994 reform

El artículo describe las características centrales de la reforma regulatoria al sector eléctrico en 1994 y evalúa el desempeño y la eficiencia de las empresas públicas antes y después de la reforma. El análisis de desempeño evalúa los cambios en medias y medianas en ganancias, eficiencia, inversión y ventas de las empresas privatizadas en el sector. La eficiencia técnica es estimada mediante la técnica DEA en una muestra de 33 plantas térmicas de energía, que representan el 85% del parque térmico; y 12 empresas distribuidoras de energía. La muestra de plantas generadoras está compuesta por plantas que estaban activas antes de la reforma y plantas nuevas que entraron en operación después de la reforma. Los principales resultados muestran que la eficiencia mejoro después de la reforma y que la política regulatoria ha tenido un efecto positivo en la eficiencia de la generación térmica de energía. Por el contrario, las distribuidoras de energía menos eficientes empeoraron después de la reforma y no llevaron a cabo una reestructuración para alcanzar la eficiencia productiva respecto a las empresas que conforman la frontera de eficiencia en distribución de energía.
