INSPECCIÓN DEL TRABAJO Y REDEFINICIÓN DEL DERECHO DEL TRABAJO
Authors: Oberto Thania , Sánchez Miguel
Published: October 2022

Esta investigación tiene como objetivo analizar el papel que la Inspección del Trabajo puede ejercer en la redefinición del Derecho del Trabajo en un mundo donde existe una reducción significativa y creciente de los trabajadores bajo relación de dependencia. Las nuevas formas en que se están organizando las actividades económicas buscan desdibujar la tradicional relación de trabajo, con el fin de evadir o desaparecer las obligaciones laborales. La idea es eliminar la figura del trabajador dependiente y con ello la protección propia del derecho del trabajo. Para lograr el objetivo propuesto, se realizó una investigación documental y de nivel descriptivo. Se concluye que el crecimiento de la informalidad hace que exista una masa de trabajadores que no se encuentren protegidos por la legislación o lo están de manera parcial, encontrándose al margen de los derechos laborales. El uso de la tecnología es uno de los elementos que ha facilitado en algunas actividades económicas la desprotección laboral y el encubrimiento de las relaciones de trabajo. La inspección del trabajo al estar en contacto directo con la realidad laboral puede mostrarla y dar a conocer al Estado las deficiencias de la legislación, con el fin de que se vayan introduciendo los cambios requeridos en materia legislativa laboral para lograr el redimensionamiento de todos los elementos existenciales de la relación de trabajo y alcanzar la redefinición de un Derecho del Trabajo que vaya en consonancia con los avances tecnológicos y el resguardo del proceso social de trabajo y de la anhelada justicia social.

Published: October 2022

Rice (Oryza sativa) is a vital staple food crop in more than 60 percent of the world, and around 430 million metric tons of rice are consumed worldwide. Moreover, to reduce synthetic fertilizer use while keeping rice production on track, the researchers decided to conduct a study on Kappaphycus drippings (K.D.) foliar fertilizer in rice production at Brgy. Mangayon, Compostela, Davao de Oro from July to December 2019 to determine the effects of different rates of synthetic fertilizer (S.F.) supplemented with Kappaphycus drippings (K.D.) foliar fertilizer on the growth and yield performance of rice and the return of cost production (RPC). Randomized Complete Block Design (RCBD) was used in the experiment, with six treatments replicated four times. The six treatments were as follows T1 - 100% SF (Control), T2 - 90% SF + KD, T3 - 80% SF + KD, T4 - 70% SF + KD, T5 - 60% SF + KD and T6 - 50% SF + KD. The experimental plot has a 4 x 4-meter dimension. The study results showed that K.D. foliar fertilizer positively impacted rice plants' growth performance, particularly on the plant height, leaf color index (LCI), and the number of tillers and productive tillers per hill and, at the same time, reduced the rice bug population. Furthermore, rice yield was positively influenced by K.D. foliar fertilizer and increased return on production cost despite the lesser rates of synthetic fertilizer (S.F.).

Published: October 2022

How to obtain a high return and face the low-risk investment is a hot topic widely discussed among investors. However, the specific method of targeting the optimal portfolio requires sophisticated mathematical computations. By research, some scholars found that the theory of portfolio helps investors to get a higher return and reduce investment risk. Thus, the aim of this paper is to collect and optimize a selected portfolio—Apple, Google, Netflix, Tesla, and Walmart—by GARCH model and Sharpe ratio, based on the mean returns and correlation matrix, among which Google and Apple are strongly positively correlated to each other, while Walmart, Tesla, and Netflix are weakly positively correlated. The price return of GARCH volatility of each equity shows the stock returns will go down in the next 7 days. We compare the optimal portfolio with NASDAQ composite to find the superiority of our model.

China's unique "semi-mandatory dividend policy" makes information conveyed by the disclosure of domestic cash dividend policy is different from the western scholars research and have it’s own new connotation. The "semi-mandatory dividend policy" makes it more difficult for investors to interpret the message of dividend policy and make rational decisions. At the same time，it also makes the market reaction of dividend policy more complicated in the further study. The announcement of mixed dividend policy and non-dividend policy caused a significant rise in stock prices. The CAR (-2, 2) of the companies’ stock with non-dividend policy have the highest average. The results show that China's capital market is more keen on stock speculation. The "speculation" and "arbitrage" behavior of institutional or individual investors on stocks will have a certain impact on the stock price after the announcement of dividend policy. Based on the relevant conclusions of the empirical study and combined with China's relevant policies, his thesis makes an in-depth analysis of the reasons why the disclosure of cash dividend, mixed dividend and non-dividend policy affects the stock price.

From the perspective of the company's long-term and stable development, it is particularly critical to select the most appropriate form of equity incentives according to the life cycle and its own development stage. This paper summarizes the relevant literature on equity incentives and life cycle at home and abroad, and finds that most scholars believe that equity incentives can often achieve the expected incentive effect, and the equity incentive plan based on the perspective of life cycle can also help to further enhance the positive effect of equity incentives.
Model Comparison between CAPM and APT: With focus on application of Factor Models
Authors: Wu Ruijun
Published: October 2022

Asset pricing theory has been one of the most rapidly growing research fields of western financial theory in the past few decades and one of the most significant theoretical tools extensively used in the financial industry, which attempts to interpret  the price or value of assets paid in the future under uncertain circumstances. With increasingly more research on comparison between financial factor models, it is sometimes hard for scholars to have an explicit comprehension of various study of a certain topic. This paper aims to collect and analyse past research on comparing CAPM and APT, specifically focusing on the application aspect. The paper found that the CAPM needs careful time horizon screening while APT is more flexible. However, APT requires more data analysis for factor selection and sensitivity measurement. Both models prefer markets with many assets. The results of the paper provides useful information and insights to scholars who intend to do empirical study on the two models in hands on data collection preparation and model fitting process, which could potentially help them save time from try-and-error.

Authors: Yao Lin
Published: October 2022

With the development of society, investors have begun to realize the paramount significance of investing. The majority of investors prefer to know more about brands they are familiar with, like Starbucks, a worldwide brand. However, whether it is worth investing in Starbucks is unsure. Consequently, this study used three methods (P/E, EV/EBITDA and P/S) to make an analysis of the investment strategy of Starbucks. There are two findings in this study. Firstly, four comparable companies should be chosen and then use the three methods, respectively, to get the average fair value of Starbucks. Secondly, by comparing the up-to-date stock price with the value calculated, it is found that the value obtained by all approaches is smaller than that shown on the website. Consequently, Starbucks is undervalued. As time goes by, if investors invest in Starbucks at this time, the stock price might go up to its fair value, bringing investors considerable revenue. Thus, it suggests that this paper helps investors get an optimal investment strategy for Starbucks. In addition, Starbucks will also benefit from this paper due to the detailed description of stock evaluation.

Authors: Zhao Yiwen
Published: October 2022

Under the impact of the epidemic, the economy of all countries has been affected to varying degrees, and the most obvious common one is that the global inflation rate has risen, thus resulting in the phenomenon of purchasing power deviation. The focus of this paper is that the traditional Capital Asset Pricing Model (CAPM) lacks the prediction of this part of the risk, so it can not realize the original intention of THE CAPM Model, completely to wash away this part of the risk. As well as the domestic and foreign research review in recent years, the literature analysis, the conclusion is drawn, in view of the traditional CAPM in the international portfolio investment deficiency, as well as the applicability in the real financial market, this paper suggests that under the purchasing power parity offset, the use of high-order CAPM through the international portfolio investment is a more stable choice.
An Empirical Study on the Impact of Fed Rate Hikes: Perspective from Fama-French Three-Factor Model
Authors: Zhao Yihang
Published: October 2022

The Fed’s interest rate hike is currently a hot issue of social concern. Some researchers believe that the Fed's rate hike this time is an "urgent cycle" rather than a "long-term cycle". However, there is still no unified explanation for the formation mechanism and scope of influence behind it. Therefore, this paper collects the return data of the US stock industry and conducts a Fama-French three-factor regression analysis. Research shows that the short-term negative impact of the U.S. stock market in the context of the Fed raising interest rates is not conducive to the development of the U.S. stock market, meanwhile, the energy industry benefits from the hike on the long term. The fed rate hike will have a negative impact on the rest of the industry in the short term, with the durable goods sector and business equipment sector having the most severe impact, and the utility sector and non-durable goods sector having a relatively small negative impact.

The traditional accounting information system provides lagging information which not only affects the quality of the information but also reduces the It's relevant and is gradually losing its value.
