Colombia Firm Energy Market

A firm energy market for Colombia is presented. Firm energy—the ability to provide energy in a dry period—is the product needed for reliability in Colombia’s hydro-dominated electricity market. The firm energy market coordinates investment in new resources to assure that sufficient firm energy is available in dry periods. Load procures in an annual auction enough firm energy to cover its needs. The firm energy product includes both a financial call option and the physical capability to supply firm energy. The call option protects load from high spot prices and improves the performance of the spot market during scarcity. The market provides strong performance incentives through the spot energy price. Market power is addressed directly: existing resources cannot impact the firm energy price. Since load is hedged from high spot prices, the market can rely on high prices to balance supply and demand during dry periods, rather than rationing.Auctions

Simulation of the Colombian Firm Energy Market

We present a simulation analysis of the proposed Colombian firm energy market. The main purpose of the simulation is to assess the risk to suppliers of participation in the market. We also are able to consider variations in the market design, and assess the impact of alternative auction parameters. Three simulation models are developed and analyzed. The first model (Model 1) uses historical price data from October 1995 through May 2006 to assess the performance risk of hypothetical thermal and hydro generating units. The second model (Model 2) uses historical price and operating data to assess performance risk of the actual generating units in Colombia over the same period. This analysis allows us to assess company risk. The third model (Model 3) differs from the other models in that it explicitly models the firm energy auction and investments going forward. Thus, the model is able to assess how the distribution of firm energy purchases differs from the firm energy target, and how this distribution depends on the firm energy demand curve. Model 3 also studies the investment decisions of suppliers, the impact of lumpy investments, and the impact of a higher scarcity price. Taken together, the simulation results demonstrate the risk reducing benefits of the firm energy market. Provided there is competitive new entry in response to load growth, the firm energy market should work well at coordinating investment in new supply, while minimizing supplier and consumer risks.Auctions

Wind Energy in Colombia: A Framework for Market Entry

The purpose of this report is to provide decision makers in Colombia (and by extension other countries or regions), who are considering the deployment or consolidation of wind power, with a set of options to promote its use. The options presented are the result of an analysis of the Colombian market; this analysis included simulations and modeling of the country’s power sector, and extensive consultations with operators, managers, and agents. More information on the analysis and simulations is presented in the appendixes. Wind was chosen to exemplify the range of renewable energy alternatives available to complement traditional power sector technologies on the basis of its technical maturity, its relatively low cost compared to other options, the country’s experience, and its wind power potential.wind energy, Colombia

Auctioning Long-term Gas Contracts in Colombia

This paper presents an approach to auctioning long-term gas contracts in Colombia. I propose an annual auction for long-term firm gas contracts. The auction would assign and price all firm gas contracts, with the exception of gas from the Guajira field, which is assigned administratively at a regulated price. The proposal is a partial market design in that it does not address the transportation of gas from producer to consumer.Auctions, gas auctions

The impact of minimum wages in Mexico and Colombia

There are diverging views about how minimum wages affect labor markets in developing countries. Advocates of minimum wages hold that they redistribute resources in a welfare-enhancing way, and can thus reduce poverty, improve productivity, and foster growth. Opponents, on the other hand, contend that minimum wage interventions result in a misallocation of labor and lead to depressed wages in the very sectors - the rural and informal urban sectors - where most of the poor are found, with the effect of wasting resources and reducing the growth rate. Data from Colombia and Mexico for the 1980s provide an opportunity to evaluate the impact of minimum wages. In Mexico in the 1980s, the minimum wage fell in real terms roughly 45 percent. By 1990, Mexico's minimum wage was about 13 percent of the average unskilled manufacturing wage. During the same period, the minimum wage in Colombia increased at nearly the same rate, reaching roughly 53 percent of the average unskilled wage. The author charts how the mandated minimum wage affected the demand for skilled and unskilled labor in both countries during that decade. Findings are as follows. In Mexico, minimum wages have had virtually no effect on wages or employment in the formal sector. The main reason: the minimum wage is not an effective wage for most firms or workers. In the informal sector, in turn, there is considerable noncompliance with the mandated minimum wage, especially among part-time and female workers. As a result, significant numbers of workers are paid at or below minimum wages. In Colombia, minimum wages have a much stronger impact on wages, judging from their proximity to the average wage and both cross-section and time series estimates. The estimates imply that the elasticity of low-paid unskilled employment with respect to minimum wages is in the range of 2 to 12 percent.Wages, Compensation&Benefits,Environmental Economics&Policies,Labor Policies,Banks&Banking Reform,Municipal Financial Management,Environmental Economics&Policies,Wages, Compensation&Benefits,Child Labor,Banks&Banking Reform,Municipal Financial Management

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

This paper describes the core features of the power sector 1994 regulatory reform and evaluates utility performance and efficiency before and after the reform. The performance analysis assesses the changes in means and medians of a series of profitability, efficiency, investment, sales of the privatized power holdings. Technical efficiency is estimated through DEA technique in a sample of 33 power thermal-plants that account for 85% of the thermal park and 12 distribution utilities. The sample units are plants that were active before the reform and new entrants that started business operations after the reform. The main outcomes show that efficiency scores have improved after the reform and that regulatory policy has had a positive effect on technical efficiency in thermal power generation. In contrasts the less efficient power distributors got worsened after the reform and were not able to undertake plant restructuring in order to catch up productive efficiency with respect to the best practice production frontier. ******************************************************************* 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.Privatization, industrial restrucuring, Colombian power sector, regulatory reform

Privatization in Colombia: A Plant Performance Analysis

This paper describes the privatization program carried out in the productive sector of the Colombian economy during the 1990s. It evaluates privatization within the policy context of general market deregulation and the promotion of private investment in the provision of public infrastructure and domiciliary public services. Two case studies are explored: the manufacturing and power sectors. The paper follows the ex-post measuring and econometric analysis of a set of operative and restructuring performance indicators for the privatized firms. For manufacturing, the study sample consists of 30 large manufacturing firms of which the Instituto de Fomento Industrial was the founding or supporting partner. The main findings suggest that those firms followed pro-cyclical behavior relative to their private competitors and undertook tight plant operative restructuring. For the power sector, the paper studies the impact of regulatory reform on market entry, ownership structure, market competition, and productive efficiency of the privatized holdings. The results suggest that privatization and entry competition in power generation have had a positive effect on the privatized utilities’ efficiency and investment. With respect to thermal generation, the measurement of productive efficiency follows a data envelope analysis technique based on a sample of 33 plants that account for 85% of the installed capacity. The sample units are plants that were active before the reform and new entrants that started business operations after the reform. The main outcome shows that efficiency scores have improved after the reform and that regulatory policy has had a positive effect on productive efficiency.

Perfomance and Efficiency in Colombia's Power Distribution Sistem: Effects of the 1994 Reform

We asess evolution in perfomance, efficiency and productivity of Colombia's power distribution utilitiesbefore and after the 1994 regulatory reform that introduced electricity market activities for the power sector in 12 distribution companies from 1985 to 2001. Perfomance is evaluated contrasting changes in meanand median by Wilcoxon Rank Sum and Pearson test on financial and other perfomance indicators. Technical efficiency is measured by means of Data Envelopment Analysis (DEA). The nature of the dataset allows the the estimation of Malmquist productivity index and its evolution in time. Results show a recovery after thereform in the mains perfomance indicators of profitability, parcial input productivity, and output. Plantefficiency and productivity increased after de reform, mainly in the largest utilities used as benchmarks inthe DEA efficiency scores measures. Meanwhile, the less efficient power distribution companies did not improve after the reform and were not able to undertake plant restructuring to chatch up in plant efficiency with respectto the Pareto efficient input allocation. Econometric results on DEA efficiency scores suggest a positive effectof policy reform.Electricity distribution, productive efficiency, power sector Colombia, Malmquist productivity index

Transacciones basadas en información privilegiada y conducción empresarial en América Latina

(Disponible en idioma inglés únicamente) A diferencia de los inversionistas externos, los grupos de control tienen la opción de realizar transacciones basadas en información privilegiada y pueden ejercerla a costa de los inversionistas externos. En este trabajo se calculan las probabilidades de realización de transacciones informadas (ITP, por sus siglas en inglés) para el universo de acciones líquidas de siete países latinoamericanos que se negocian tanto en el país de origen como en ADR, y se aplica la ITP para dar respuesta a preguntas sobre la conducción empresarial. Se halló una heterogeneidad considerable de las ITP dentro de un entorno institucional. No obstante, se identificaron diferencias significativas de la ITP media entre gamas de volumen, países y tipos de título valor. La ITP guarda una correlación intuitivamente llamativa con algunas de las variables de protección de inversionistas en el ámbito nacional que se emplean en la obra publicada (no con todas). Se hallaron incrementos considerables de la ITP justo antes de efectuarse anuncios empresariales públicos, lo que sugiere que hay agentes informados privadamente que están explotando su privilegio cuando existe la posibilidad de obtener su mayor valor. La ITP adquiere su valor en el mercado: las compañías con mayor ITP registran un menor coeficiente de Tobin. Se concluye que el mercado parece reconocer y valorar acordemente las variables sustitutivas no observables de la probabilidad de realización de transacciones informadas (ITP) de la calidad de la conducción empresarial, tal como la heterogeneidad del comportamiento de la empresa.
