Does the Size of the Business Still Matter, or Is Profitability under New Management, by Order of the COVID-19?

Businesses should come up with a strategy, plans, and goals so that their total assets can make a profit during the transformation process. Utilizing various features of a property can generate this income. This comparison provides evidence of profitability. During the global economic downturn, a number of businesses encountered issues that caused their payment situations and profitability to deteriorate. The goal of this article is to ascertain whether particular profitability indicators also revealed the pandemic-related global crisis, particularly in the Visegrad Group countries. This analysis was conducted based on categories of business size. Specifically, 8671 enterprises were analyzed. The evaluation of indicators revealed whether there was a significant change in a negative direction, a significant change in a positive direction, or no significant change. It was possible to make a clear diagram of the companies that took part in the study and to figure out the median values in order to compare the results of the chosen profitability indicators. Correspondence analysis was conducted so that conclusions could be more accurate. According to the findings of this study, indicators of ROA, ROE, and ROS did not change significantly across enterprise size categories in the years preceding, during, and after the pandemic. Since the government regulations of the V4 countries had a significant impact on these businesses, the change was most obvious in the case of small businesses within the ROS indicator. The added value of the article is derived from its analysis of selected profitability indicators in the largest group of Central European nations and its relevance.

Metamorphoses of Earnings in the Transport Sector of the V4 Region

The transportation sector is a crucial sector of the sustainability of every national economy. Previous studies highlighted the core significance of transport enterprises in European countries over the past 60 years. The long-term sustainability of enterprises is determined by their ability to gain earnings. Thus, earnings are the synonym of significance in corporate life. The purpose of this study was to capture the lever year, the trend, and the slope of the development of earnings in the transport sector before the COVID-19 pandemic. Time series of the annual earnings of the enterprises from the close countries of the V4 region were used during a 10-year period. Buishand's test sets the change-points of the development and indicated the values of specific central lines. The year 2013 was the lever date for the earnings of 830 Slovak and 1042 Hungarian enterprises. The year 2015 was the year of momentum for 757 Polish enterprises. The development of 397 Czech enterprises was mainly influenced by the year 2014. The results of the Mann–Kendall test detected a positive trend in the series of business finance in all countries. In addition, the Sen's slope was estimated in the transport sector for the analyzed period 2010–2019.

Delivery Apps Use during the COVID-19 Pandemic: Consumer Satisfaction Judgments, Behavioral Intentions, and Purchase Decisions

The aim of this systematic review is to synthesize and analyze existing evidence on delivery apps use during the COVID-19 pandemic. With increasing evidence of app-based sales systems, there is an essential demand for comprehending whether perceived control over food delivery apps may strengthen consumer feelings. In this research, prior findings were cumulated indicating that consumer habits in identifying information as regards ready-to-eat food and making decisions accordingly have reconfigured online delivery. We carried out a quantitative literature review of ProQuest, Scopus, and the Web of Science throughout January 2022, with search terms including "delivery app" + "COVID-19 pandemic," "consumer satisfaction judgment," "behavioral intention," and "purchase decision." As we analyzed research published between 2020 and 2022, only 159 papers met the eligibility criteria. By removing controversial or unclear findings (scanty/unimportant data), results unsupported by replication, undetailed content, or papers having quite similar titles, we decided on 24, chiefly empirical, sources.
