*Call for Papers: Political economy of digital platforms: transformations in capitalism and responses from different countries * EPTIC Journal invites interested parties to submit papers for the Thematic Dossier “Political economy of digital platforms: transformations in capitalism and responses from different countries,” which will be coordinated by Helena Martins (UFC) and Rodrigo Moreno Marques (UFMG). The publication will inaugurate a series of three special dossiers related to the project "The economic governance of digital networks: for an analysis of markets, internet competition, and their impact on user rights," developed by the Observatory of Economics and Communication (Obscom) at the Federal University of Sergipe (UFS), with funding from Fapesp (21/06992-1). Texts must be submitted by November 15, 2025. The issue is expected to be published in March 2026. The Political Economy of Information, Communication, and Culture has linked the process of platformization and the emergence of digital platforms to the structural crisis in capitalism, which involves monopolization, concentration, and centralization of capital, stagnant growth in core countries, growing inequalities, financial instability, ecological crisis, and disputes over national sovereignty. As part of this context, technological transformations, from the microelectronic revolution to artificial intelligence, are not just autonomous phenomena, but constitute an attempt by capital to respond to this set of crises and maintain its accumulation process. As instruments of monopolistic economic agents, platforms do not act only as central intermediaries between producers, citizens treated as consumers, advertisers, and other groups. In fact, they act as vectors for the reorganization of capital, enabling data capture and control, monetization of attention, intermediation of exchanges, intensification of work, and value capture in sectors in which they operate, reproducing old relations of national dependence and creating new relations of dependence at the macroeconomic level. Specifically with regard to the cultural industry, they also reorganize the structure of social mediation, with significant power to control the production and circulation of content associated with new forms of manipulation. This general situation affects different countries in different ways, given the unequal international division of labor. We are interested in discussing how the capitalist structural crisis and the actions of platforms manifest themselves in Latin American countries, given the historical technological dependence, the appropriation of wealth, and the exploitation of labor and natural resources by large global corporations, which increases the risks to already fragile national sovereignties and regulatory regimes. This is evident in Donald Trump's threats against countries, including Brazil, that have debated or proposed new regulations on platforms, artificial intelligence, and other technologies. The reactions and national policies of countries such as China and Russia in the face of this complex reality are also emblematic. The impacts of this reconfiguration are diverse, ranging from forms of accumulation to the very organization of the political regime of democracy. Therefore, the dossier hopes to receive texts on: - The relevance and mobilization of classical concepts (value, commodity, labor, and others) for the observation of digital transformations; - Characterization of the current stage of capitalism and its relationship with information and communication technologies; - Geopolitics, wars, genocide, and the role of digital platforms; - Transformations in the world of work associated with platform mediation; - Data sovereignty, digital sovereignty, technological sovereignty, and popular sovereignty; - Regulation of platforms and digital services; - Digital monopolies and monopolization of digital markets.
