The theory of disruptive technologies/innovations is one of the most influential theories on how companies and industries respond to technological change. Over the years, the theory of disruptive innovations has undergone changes in relation to its initial concept, which has led the theory to be applied in different contexts. In dissonance, the academic literature has not yet provided a clear picture of the impact of disruptive innovation on new markets. This theoretical essay seeks to revisit the concept of disruption that affects existing structures of the main market and/or creates an opportunity for a new market. In this way, this essay seeks to review the concept of disruptive innovation presented in the literature and present an academic perspective of disruption and creation of new markets. This theoretical essay presents a recap of the theory of disruptive innovations, its different concepts present in the literature, its non-compliance with current models, standards and markets, and its potential to affect existing market structures and create new markets. Despite the different concepts employed, a new value architecture is presented in most proposals, where disruption is found in the development of new disruptive technologies and their integration into new business models. This theoretical essay seeks to contribute to a better understanding of the concept of disruptive innovations, especially with their impact on the development of new markets. [ABSTRACT FROM AUTHOR]

The internet revolution profoundly altered economic relations, with the developing of new technologies and commercial practices. This article scrutinizes how markets involved in this reality can facilitate anti-competitive behavior. It posits that the structure of these markets can enable new manifestations of anti-competitive practices, challenging traditional premises of competition law. The methodology, regarding the procedure, consists of the literature review of competition and the Google Shopping case study, decided by the Brazilian Economic Defense Council (CADE), in 2019. While technically approaching the characteristics of these markets - such as zero price, multiple sides and attention -, one can visualize the way in which the abuse of a dominant position can be revealed in digital markets, through the handling of big data and the consequent consolidation of economic power. When exploring the different views of the case study, even with divergent views of the decision makers, it is pointed out the need to rethink concepts in the analysis of anti-competitive behavior in digital markets.

The broiler production chain in Mato Grosso do Sul has a market structure similar to that of a competitive oligopoly, with high concentration, no differentiation from and no market dominance by agents. In this work we sought to analyze the effects of a concentrated market structure for the performance of the production chain, as well as its relationship and interaction with the rest of the state economy. From the background provided by the input-product model, the sector's low direct contribution to the generation and spillover of the multiplicative effects of employment (E), income (R) and production (VA) was found. The results enable a better understanding of the broiler production chain and the reflexes of a market structure concentrated in the economy. [ABSTRACT FROM AUTHOR]

Halal broilers for the market of Islamic countries make up 35% of exported broilers from Brazil. Halal production standards have several peculiarities and affect the market's competiveness. The latter has numberless ways of interpretation and measurements that depend on the theoretical approach. Current study analyzes the characteristics of the Institutional Environment that limits a specific market and identifies the main barriers for the introduction of new companies. Barriers characterize the structure of a specific market and they protect the consolidated firms due to the imposition of costs to potential novel companies. Characteristics may be observed in informal (religious and cultural aspects) and formal (legislation) institutions. [ABSTRACT FROM AUTHOR]
