Authors: Guo Zhichao
Published: November 2023

With the continuous accumulation of theoretical knowledge and progressive applied research, analyzing financial time series data gradually becomes everlasting research in modern days. The simpler Dickey-Fuller originally is a test commonly used in econo-metrics and finance to test the stationarity of financial time series data. Thereafter, simpler Dickey-Fuller is eventually extended to the augmented Dickey-Fuller test to examine the stationarity of financial time series data such as stock prices, returns, and so on. This paper mainly focuses on the utilization of the augment Dickey-Fuller test and tests the stationarity of stock prices and returns for Nike, and Amazon. Both the stock price which is non-stationary, and the return, which is stationary, illustrate that these two companies are market-efficient. Additionally, the paper provides plots of stock prices and returns for these two companies by executing Python code. The results from the augment Dickey-Fuller test not only verify the characteristics of these plots but also indicate that the augment Dickey-Fuller test is useful to predict stock price and return.

Authors: Chai Tianrun
Published: November 2023

This study investigates the application of the Markowitz Model in optimizing portfolios of high-end companies. By analyzing a 20-year dataset spanning 2001 to 2021, this paper explores the construction of efficient and minimum variance frontiers and their performance compared to the index model and the naive portfolio approach. The findings highlight the limitations of relying solely on historical data, as past performance may not accurately predict future outcomes due to evolving market conditions and company-specific factors. Additionally, the study emphasizes the need for incorporating practical factors such as transaction costs and liquidity constraints into the evaluation of portfolio optimization models. Furthermore, the study acknowledges the limitations of its focus on certain companies, recognizing that findings may not be directly applicable to other regions and markets with differing economic, regulatory, and industry dynamics. While the Markowitz Model offers a sophisticated framework for portfolio optimization, it is important to consider these limitations and conduct further research to enhance its effectiveness in diverse investment contexts.

Walmart is a retail industry leader, and its growth and success have given the company a measure of reference significance. Analyzing the retail industry's current market condition, resolving the challenge, and providing strategic reference for other businesses may all be accomplished by studying Walmart's approach to marketing. This study examines the following aspects of Walmart's marketing strategy through literature review and analysis method: market segmentation, market target, and market positioning, with an eye on the theory underlying each of them. The research concluded that Walmart used population, geography, and the purchasing power of different consumer groups to divide the market into distinct segments, and that the company used both a generic marketing strategy and a more targeted marketing strategy to meet customer demand for its low prices and convenient locations. Walmart has made tactical tweaks to the aforementioned marketing methods to account for the ever-shifting nature of the market. In order to pursue the sustainable development of businesses, the paper adopts a more complex and humanized segmentation principle, modifies the market target strategy and market positioning, and upgrades the positioning to energy conservation and environmental protection.
Impact of the Sino-US Trade War on Factor Endowment in the Guangdong-Hong Kong-Macao Greater Bay Area: A Perspective from Factor Endowment Theory
Authors: Bao Kuo
Published: November 2023

This study chooses the Guangdong-Hong Kong-Macao Greater Bay Area as the research object to explore the impact of Sino-US trade barriers on the factor endowment of the region. Based on the factor endowment theory, this paper proposes a hypothesis, tests collinearity, and establishes a multiple linear regression model. The results show that the trade barriers between China and the U.S. cannot explain the changes in GBA's factor endowments since the fitting degree is low. The correlation test shows the substitution effect between factor endowments. Based on the data analysis results, Sino-US trade barriers did not affect the factor endowment of the GBA. The possible reasons are the trade deflection and the policy that restrict factor mobility.

Being the central bank of the United States, the Federal Reserve wields significant impact in global finance and macroeconomics. The policy of increasing interest rates has sparked extensive debate and apprehension as it profoundly affects the worldwide financial landscape. After thorough examination of relevant literature and research findings, we ascertain that monetary policys impact on global financial markets can be primarily understood through several key aspects: 1) The impact of interest rate hikes on the stock market is predominantly negative, which may lead to capital outflows, dampened consumer sentiment and higher borrowing costs. 2) Interest rate hikes have an impact on changes in interest rates in the bond market, which may lead to increased debt expenses and inversions. 3) The interest rate hike influences the exchange rate changes in the foreign exchange market, attracting funds into the United States, resulting in other countries facing the risk of capital outflow and currency depreciation. This article explores the global impact of the Federal Reserves interest rate hikes on financial markets and provides valuable insights for policymakers and investors. Given the potential negative consequences of rising interest rates on stock and bond markets, investors may find it prudent to adjust their portfolios accordingly. Simultaneously, it is crucial to closely monitor global economic dynamics and monetary policies while maintaining flexibility in responding to market fluctuations.

Netflix and binge viewing have gained increasing popularity among the new generation of TV and movie viewers since they are more convenient and can provide customized watch-ing services. This paper is focused on the unique business model of Netflix and seeks to find out why it once became popular among Chinese viewers. A crucial reason is that Netflix has made a committed effort to create and promote original content. It keeps a keen eye on viewers needs by creating a tailored and remarkable TV viewing experience. However, the negative impacts of binge-watching behaviour cannot be ignored. It is now considered an important reason for loneliness and a low degree of cognitive function. Overall, the paper employs secondary data analysis, which offers a critical review of previously collected data in the new research area.
Merger and Acquisitions of Internet Companies: A Comprehensive Analysis
Authors: Lu Runlin
Published: November 2023

With the rapid development of the Internet, the world has entered the Internet era - new technologies such as Big data, artificial intelligence and cloud computing are rapidly changing people's lifestyle and consumption concepts. At the same time, competition among internet companies is also very fierce, and after rapid growth, internet companies will also face certain business growth bottlenecks. In this context, if a company wants to expand its business scale, in addition to relying on its own endogenous growth, it usually chooses to implement mergers or acquisitions. By integrating the advantageous resources of enterprises in the same industry or upstream and downstream, the goal is to integrate the value chain, increase market share, and achieve diversified development. This article compares and analyzes two merger and acquisition cases in the Chinese internet industry, exploring the key factors behind mergers and acquisitions, and hoping to provide some inspiration for the merger and acquisition of internet enterprises.

This paper builds on the existing literature on the effect of unionization on OSH by providing an analysis of unionization’s effects on COVID-19 mortality. It combines data from the NVSS with the CPS into a unique dataset. It finds that a 10 percentage-point increase in unionization is associated with a reduction in mortality from 26 per 100,000 workers to 24 per 100,000 workers. This means that if the United States had the union density of 35 percent that it had in 1954 instead of today’s rate of 10 percent, the COVID-19 mortality rate for working people would have fallen from 26 to 19 per 100,000..
A Review on the Impacts of Toposequence on Soil Properties
Authors: Omokaro Godspower Oke
Published: November 2023

This study demonstrates the significant influence of toposequence position on soil properties and hydrological conditions, affecting crop yield. Variations in toposequence position lead to differences in soil properties; physical and chemical properties may vary minimally or maximally depending on the slope’s location. As slope increases, soil moisture and organic carbon rise, while bulk density, pH, and soil temperature decrease. Soils along a toposequence reveal that landscape position, erosion, aspect, and drainage impact soil depth, particle size distribution, and CEC. Understanding topography’s influence on soil characteristics is crucial for evaluating soil productivity and devising conservation strategies. This knowledge is essential for assessing soil value and avoiding uneven input distribution in agricultural fields on diverse terrains. This review paper summarizes the impacts of toposequence on soil physical and chemical properties. The study utilized databases such as Google Scholar, African Journals Online (AJOL), Scopus, Web of Science, ScienceDirect, and Directory of Open Access Journals (DOAJ) to identify relevant studies.

This study investigated farmers’ perceptions of practices in crop production in relation to soil health in Sapele, Delta State. The results obtained from demographics show that most of the farmers were experienced men and women. In terms of farming experience, they were highly exposed. However, only a few of them had attained tertiary education, which explains their limited exposure to soil management practices and their effects. The study revealed that most crops, such as maize, had a growing cycle of 0-6 months. Cassava, on the other hand, took 12 months to reach full maturity and was predominantly cultivated on 2.5-5 acres of land owned by individual farmers. Mixed cropping was practiced because it allowed farmers to cultivate a variety of plants and crops. The climate, temperature, and vegetation of the Songhai community were conducive to planting. Regarding farming and soil fertility, many farmers relied on bush fallowing as their primary source of income. Weeds and other agents that reduce productivity and profitability were mainly controlled through mechanical methods, traps, and introducing biological pest enemies. To improve crop yield and soil health, organic manure, especially from poultry droppings, was the most used due to its availability and low cost. Farmers understood the importance of good soil health management practices and were open to adopting new methods, such as microbial inputs, to enhance soil health and crop yield. The study suggests that additional research is needed to identify measures farmers are likely to adopt to protect publicly owned natural resources. Furthermore, the government should encourage the development of general guidelines for obtaining indicators and their use to monitor improvements in soil health.
