“…There are also indications that maternal grandmothers are more important in industrialized societies and paternal grandmothers in traditional societies (Coall et al 2018;Kaptijn et al 2013;Snopkowski and Sear 2015). Many traditional societies are patriarchally oriented, with sons being considered more important than daughters.…”

Objectives Evolutionary theory predicts grandmothers to invest more in their daughter's children than in their son's children, because of the higher likelihood of being genetically related to their daughter's children. At the same time, most African cultures are characterized by male dominance, which might make it more profitable to invest in sons than in daughters. Here, the relative importance of paternal versus maternal grandmothers for children's schooling is studied as well as how this grandmother gender effect varies across circumstances. Methods The importance of paternal versus maternal grandmothers for children's schooling is studied using multilevel logistic regression analysis on data for 896,073 children aged 7-15, living in 33 sub-Saharan African countries. We control for demographic and socioeconomic factors at household and context level and study the role of circumstances using interaction analysis. Results Children living with a paternal grandmother have a higher chance of being in school than children living with a maternal grandmother. This effect is larger for boys, when the father is higher educated and when a grandfather is present. It is reduced when mother's education level is higher. Conclusions Children living with a paternal grandmother have better schooling outcomes relative to those living with a maternal grandmother. This advantage of living with a paternal grandmother is stronger for boys and when the father is higher educated. Male dominance as a cultural factor seems to be more important for grandmother's investments than certainty about genetic relatedness. Only a higher education level of the mother seems to counterbalance this tendency to a certain extent.

“…Miller first synthetically considered disagreement and short selling obstacles in 1977. He believes that investor disagreement will lead to a decline in future stock returns (Coall et al, 2018). The greater the investor disagreement, the stronger the issuer's restrictions on short selling of the stock, which means that the stock price is largely overvalued.…”

The phenomenon of high first-day income and high break-up rate in China's capital market has long attracted the attention of investors. Based on the disagreement model, in combination with the information asymmetry theory and behavioral finance, a mathematical model was put forward to analyze the reasons and mechanisms for the excess return of the initial public offering (IPO) on the first-day under the influence of investors' sentiments. The analysis shows that the IPO first-day income is a function of the disagreement between investors, which generally presents an asymmetric U shape. Information asymmetry affects the degree of valuation deviation. The sentiment of investors reflects the psychological state of the investor at the time, which makes the income increase or decrease under the influence of investor sentiment and market sentiment. In turn, it leads to the emergence of excess returns or break-up rates on the first-day. The research results help deepen the understanding of the IPO pricing mechanism and explore the impact of investor psychology on its pricing, putting forward suggestions for the issue pricing mechanism of the Sci-Tech Innovation Board.

This research paper discusses the application of multiagent simulation model of production processes by reference to milk receiving and storage. The paper describes basic parameters for general models, and presents the experiment results obtained during the model processing, as well as the approach towards implementation of the multiagent system employing AnyLogic simulation environment. The introduction of general technique to plot multiagent simulation models allows to use digital tools to create a virtual copy of the true-life processes with the possibility to provide forecast and identification of the food production industries. The employment of simulation modeling enables refinement of the production process under study, identification of its weaknesses, and provision of the expert opinion on improvement of production processes and as regards the results of virtual testing thereof.
