The worldwide pandemic of the new coronavirus is an external event that has been impacting economic sectors, with the technology sector being positively impacted by an increase in demand for products and services related to information technology. Motivated by the essentiality of the information technology sector, this study aims to analyze the behavior of stock returns of companies in the information technology sector listed on B3 during the Covid-19 pandemic. Descriptive methodology was used, with a quantitative approach for data analysis, regarding the procedures, it was classified as an event study. The initial sample comprised 14 firms from the information technology sector listed in Brazil, Stock Exchange, Counter (B3) and plus the Ibovespa index, 9 firms were eliminated for not presenting results throughout the analyzed period, leaving the final sample with 5 firms, with daily data for the period from 03/12/2019 to 03/12/2021 (2,766 daily observations). The results suggest that the Covid-19 pandemic affected the returns of the information technology sector, which after the start of the pandemic presents returns higher than the Ibovespa Index, however, when analyzing the persistence of returns, the results are significant in only some months.

Based on long-term ethnographic research in state-run settlement projects on former sugarcane plantations in Northeast Brazil, this article questions the evidence of "the economy" as a privileged framework for understanding the life situation of the poor, structured by precariousness and uncertainty about the future. Exploring the polysemy of Portuguese esperar (to wait, to hope, and to expect), it analyzes the plurality of orientations to the future among former sugarcane wageworkers included as beneficiaries in land reform projects, and their strategies to mitigate uncertainty in various configurations. If radical uncertainty lies out of reach of human hands, relative uncertainty may be acted on by mobilizing people. While money is desirable, it has a transitory character; and the value of friends lies in their potential to help, especially in case of a crisis. Ethnography thus suggests moving beyond an "economic anthropology" that aims to analyze "other economies" in order to explore the fields of opportunities and frames of reference that structure life situations and the local versions of oikonomia in its original meaning of "government of the household".

The purpose of this study was to understand the opportunistic behavior of the concepts from uncertainty, bounded rationality and asset specificity. A theoretical model was proposed and tested where the specificity was operationalized according to the dedicated, physical and human assets following Anderson and Schmittlein (1984), Carson, Madhok and Wu (2006) and Skarmeas, Katsikeas and Schlegelmilch (2002), anchored in the Transaction Cost Theory (TCT). The opportunistic behavior was operationalized as the indicators proposed by Carson, Madhok and Wu (2006). The bounded rationality has been studied from the perspective of Simon (1957, 1980) and the operationalization of the construct uncertainty in line with Knight (2002), Duncan (1972), Gordon and Narayanan (1984), Milliken (1987) and Milliken (1990). The data was collected from 111 managers in the manufacturing industry in Brazil selected on the basis of Industrial Federation of the São Paulo and submitted to Structural Equation Modeling. The results showed that bounded rationality and asset specificity positively influence the opportunistic behavior of economic agents, confirming the arguments of the theory of transaction costs, meaning that as greater the specificity of the assets less are the investment possibilities of reuse, making continuity valuable relationship and potential target of opportunistic. The results confirmed the multidimensionality of the construct uncertainty, too, reinforcing the theoretical arguments from the perspective of Uncertainty Information. This finding, with Simon (1957, 1980) definitions, enabled the operationalization of the construct bounded rationality from the uncertainty effect and response uncertainty, and the realization of the importance of this premise to explain the existence of transaction costs. In this sense the results allows a range of possibilities and contributes significantly to the advance of empirical studies in the field of TCT. [ABSTRACT FROM AUTHOR]
