This paper aims to explore university students' multitasking behavior in online classrooms and their influence on academic performance. Also, the study examined students' opinions.

A total of 302 university students fulfilled an online survey. Ten questions were focused on demographic information, five items evaluated online class behavior of students, 9 items evaluated self-efficacy and four items measured academic performance.

Multitasking behavior was found to negatively influence self-efficacy of −0.332, whereas self-efficacy showed a positive influence of 0.325 on academic performance. Cronbach's alpha and average variance extracted values were 0.780 and 0.527 (multitasking behavior), 0.875 and 0.503 (self-efficacy), 0.781 and 0.601 (academic performance). Outcomes of the bootstrapping test showed that the path coefficients are significant.

The research findings may help university managers understand undergraduates’ online and face-to-face behavior and strategies to improve the behavior to ensure the best academic outcomes. The novelty is based on using the partial least square structural equation modeling technique.

The following chapter aims to investigate the impact on the prices of inferior goods from COVID-19, a global pandemic with a spread never before seen, and in order to stipulate the possible consequences, a contrast was made with past world crises in order to speculate the state in which the country and its citizens would be economically benefited. The chapter has been based on articles previously carried out by specialists, said essays, likewise, that have been contrasted by different authors; therefore, it could be stipulated that the methodology used throughout the trial was the one applied, since it was based on prior knowledge from great scholars on the subject. The results found indicate that, even though the country is in an uncertain outlook, the possibilities of economic recovery are high since previous economic crises denote large drops in money fluctuation with a high rate of recovery.

The tension between the United States and China has not ended, despite the lengthy negotiations carried out in 2019 to appease differences and decrease protectionism over the technology industry, since the trade war was producing devastating consequences for both powers and international trade. The resurgence of tension is due to two main factors, such as mutual accusations about who is to blame for the origin of COVID-19 and the use of the new 5G mobile technology by Chinese companies like ZTE and Huawei. We developed an in-depth analysis of the consequences on international prices of the technology industry and international trade due to the reappearance of the trade conflict between China and the United States. This analysis will be carried out through the application of economic theories. There is greater distrust in the technology sector, and this produces a variation in the price of the technology industry. Likewise, according to Marshall's law of demand and supply, this effect can be explained more accurately; since there was a lower demand for technological products, the digital industry will have to lower its prices to generate income.

Food insecurity in the Latin American region has become a complex problem that significantly impacts people's physical and mental well-being. The factors causing food insecurity are varied, ranging from social, political, and economic causes. Ensuring access to food is not a task with limited responsibilities; on the contrary, both public and private institutions must contribute to creating sustainable and innovative solutions. In general, it is necessary to ensure that the food system flows correctly, ensuring the availability of balanced and nutritious food for the diet of the inhabitants of a given nation. Alternative solutions apart from the government's help include sustainable cultivation, finger millet, and close cooperation with the farmers from the agriculture sector. The present research aims to consolidate theoretical information on the Latin American situation and seek the leading solutions of the parties involved.
