In the current context throughout Latin America, where power groups and the market are increasingly interested in the natural and cultural resources of indigenous territories, indigenous peoples are once again being denied, and their identities, preexistence in the territories, and rights are being questioned. As archaeologists, we must recognize that our work is not merely about investigating past landscapes but also about conducting archaeology in territories currently intersected by recurring conflicts. This article proposes and discusses the conceptual and theoretical-methodological foundations of a committed and activist archaeology, one that contributes to social justice and the emancipation of historically subordinated minorities, such as indigenous peoples. This archaeology must be based on two fundamental premises: the recognition of indigenous peoples as subjects of rights and the implementation of interculturality. Based on these principles, two lines of work are proposed, each involving specific methods: (1) the development of demand-driven research that produces knowledge serving the projects and struggles of indigenous peoples, and (2) the creation of multivocal products where indigenous voices appear in the first person, contributing to their internal processes and their articulation with various societal and state actors. This article advocates for a transformation of contemporary Latin American archaeology, both in its relationship with the social environment where research is conducted and in the way knowledge is produced, placing the discipline at the service of the projects, causes, and struggles of subjugated minorities.

Public markets in San Cristóbal de Las Casas, Chiapas, on the one hand, are multicultural spaces, loaded with histories, migration, conflicts, resistance and defense of livelihoods, but they are also spaces conducive to misuse and management power. The objective of this paper is to make visible from within, through the narration of the merchants, the practices of the power of certain leaders. The markets will continue, the leaders fall and others will emerge; the problems will drag on as long as there is no structural attention within public policies. [ABSTRACT FROM AUTHOR]

In this paper, we study the relationship between reconciliations in the Colombian electricity market and the bid prices by firms on the spot market. In this work, we propose a model of behavior of the firm to elaborate theoretical predictions about the relationship between the reconciliations and the bid prices. Subsequently, we developed an empirical strategy to test the predictions of our model. We find that when firms expect their units to have negative reconciliations the next day, they tend to reduce the bid prices for their units. To positive reconciliations, there is no evidence of any relationship. [ABSTRACT FROM AUTHOR]

The main aim of this research is to measure the variation of market power exercised by a vertically integrated firm in the market of transactions carried out through payment cards, because of changes given by the entry of competitive firms in the market of purchasing shops, which increase the level of downstream competition in the industry. To achieve this, it is used as a model based on an oligopolistic structure where there is a leading firm and a fringe of competitive firms that compete each other, based on Stackelberg competition. The econometric model estimates indirectly the residual elasticity demand for the period January 2013-May 2020. As a result, the market power is directly related to the market share of the leading firm, equivalent to 1.14% to 114.35%, being the last predominant value in the trading account.

In this essay, we postulate the relevance of the center-periphery "vision" to characterize global capitalism in its different periods and, especially, at present. We emphasize the asymmetries between central and peripheral countries, and how they display a pattern of unequal development, where the relations of dependence between the two are understood by the subordination exercised by the central pole over the peripheral one. Global capitalism, thus configured, confers on the economic centers oligopolistic--in some cases also oligopsonistic--market powers, accentuating a rentier relationship between the two poles. As a central corollary of our analysis, we point out that center-periphery relations in the 21st century exacerbate rentierism while diversifying it, under different rent appropriation strategies related to peripheral specificities. Thus, we can distinguish a "classic" rentierism derived from the extraction of natural resources, the financial rentierism characteristic of the neoliberal phase of capitalism, and the emergence of a new digital rentierism associated with the platform economy.

The energy policies of the different countries of the European Union are marked by the community objectives of achieving a 32% of renewable energy consumption of total consumption by 2030. Although there are ambitious objectives to promote the energy transition in the EU, the development of RES has been uneven between countries. The article analyzes how the energy transition process is developing in Spain and Hungary through a comparative study of the institutional contexts on which this process is based. Two countries whose natural potential has allowed them to be ambitious in their renewable energy development projections, but which must propose a new approach to their energy systems if they want to achieve their full development. Along with structural problems such as the energy tradition linked to hydrocarbons, the monopolization of electricity markets or administrative complexity, the social and landscape dimension of renewables are emerging as new challenges for both countries. The objective of the article is to analyze the similarities and differences between the two models of energy development that allow to exemplify the various national realities behind this European objective and to understand the uneven energy transition in different European countries.

In this paper, we elaborate a theoretical model to explain how generating firms choose their aggregate position in bilateral contracts in the Colombian electricity market. Subsequently, we propose an empirical strategy to contrast the theoretical predictions of the model with data from the wholesale market. Our results show that there is evidence in favor of the hypotheses of our model. Firms tend to adjust their contracts according to the ideal generation they expect the market operator to allocate them, and the difference between marginal costs and contract prices.

The objective of this work is to predict the consumption of residential electrical energy in the Cajamarca Region through HoltWinters models. This predictive modeling procedure is useful for the short and medium term prediction of electricity sales. The forecast of electricity consumption is important in regional and national energy planning; from their results, the agents of the electric power market make more adequate decisions for their work. The Holt-Winters method was estimated for different smoothing constants, which includes methods for seasonal additive and multiplicative patterns. The value of the statistical tests of the mean absolute percentage error (MAPE) was considered as the main estimator of the capacity of the model. The additive Holt-Winters model was selected as the best prediction model, with an average absolute percentage error of 1,70 and with estimated smoothing constants of 0,4. [ABSTRACT FROM AUTHOR]

Non-conventional sources of renewable energy (NCER) are energy sources considered as a clean alternative for the energy supply versus an electric generation based on fossil fuels. In addition, they are a way by which the concentration level in the market is reduced and the participation of the demand can be given. This article presents different mechanisms of integration of these sources in the market, and analyzes their effect on the electricity price in Colombia. Under defined simulation conditions, the results indicate that a 20% share of the USRE in the coverage of demand on a distributed basis generates a 22% reduction in the electricity price for a long term.

The Royal Decree 647/2011 regulates the activity of system load managers for the energy recharge of electric vehicles. These managers are commercial companies that provide electric recharge services and can act as agents in the electricity production market, access transportation and distribution networks, and invoice and collect the energy delivered in resale. Additionally, they must acquire the necessary energy, inform their clients of its origin, and promote its rational use. The National Energy Commission is responsible for inspecting and supervising load managers to verify compliance with established requirements and obligations. This Royal Decree also establishes access tolls for low voltage consumers and promotes the development of electric vehicles and energy system efficiency. [Extracted from the article]

In this work, based on the results of a computational tool designed and developed on a free use spreadsheet, risk management techniques are applied to identify, assess and control the financial risks associated with participation in an electricity market such as the Colombian one. This project takes place in two stages. In the first stage, the simulation model was defined (using Monte Carlo simulation) for two of the actors in the market (generators and traders); using their profit margins as the objective function. In the second stage, a computational tool implemented in a spreadsheet was used to simulate the marginal benefit of these agents. The results show that the simulation tool can be used to estimate losses or benefits (profit margins) of agents according to their degree of risk aversion. [ABSTRACT FROM AUTHOR]

Upon the supposed integration process (NAFTA) for the Mexican market strategic behavior, this paper aims to measure market power during the 1990-decade second half using the structure-behavior-performance paradigm, in the context of an economy with huge asymmetries as the Mexican one and considering the Mexican market from an aggregate perspective. A lineal model is proposed that reflects the relation between structure and performance in order to show the statistical signification of the coefficient relative to concentration indexes. A methodological analysis tool is offered, which might be applied to other Latin American economies, this adds a remarkable multiplier effect in times of a profound global economic crisis, in which Latin America is particularly vulnerable due to the dependence and development conditions.

This paper presents the main findings of the work carried out by Universidad de los Andes and Universidad Nacional de Colombia, with support from Colciencias -- the Colombian National Science Development Institution) and ISAGEN, a power generation company. These results are briefed in the following items: i) The main drivers for penetration of new energy sources and cleaner Technologies (not only for electricity) in the country, will be in its order: energy basket diversification, reduction of dependence on fossil fuels (as it is the case of biofuels), minimization of environmental impact, and support to technology and industrial development. ii) Current regulation of the energy market is not explicitly against the development of these power sources and technologies, however the market architecture and rules were made thinking in conventional sources and technologies, then some adjustments should be carried out to "level de playing field" for renewable in the country, this should aim to include all external cost and benefits from its installation and operation, as well as from the participation of distributed generation in grids. iii) It is indispensable to have appropriate financial schemes for longer pay-back periods with these technologies, investors should be aware of the benefits and complementarities that can be achieved in power markets, such as emission reduction. In addition, governments should give some priority to in-country technology development and to the adoption of some of these sources when conditions are the most favourable. [ABSTRACT FROM AUTHOR]
