The classical stochastic adjustment methods only allow quarterly or monthly benchmarks to be estimated and can only be applied when high frequency is a regular multiple of low frequency. Thus, they fail to offer solutions for such problems, thereby evidencing the need to develop tools and methods for high-frequency series (daily or weekly ones). This paper obtains the first known method for using daily indicators, taking into account the different number of days for each month. The proposed Bayesian (normal-gamma) method can employ several indicators for the likelihood model, also obtaining an explicit (non iterative) solution for the optimal estimate of high frequency series. It is also important to observe that the model includes a correction mechanism for volatile indicators, as is often found in benchmarking problems for small areas. The methodology, in the line of normal-gamma specifications, allows Bayesian Credibility intervals for the estimated daily series. ","PeriodicalId":210068,"journal":{"name":"Studies of Applied Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140461192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In fact, the financial inclusion of productive and consumer units in the rural sector - above all - depends on the economic and financial sustainability of these entities. In this context, it is important to know how profitable cooperatives are in Ecuador, identifying those factors, internal and external, that explain such profitability; for this reason, this article aims to analyze the relationship between internal factors such as liquidity, management and solvency indicators; and external factors such as inflation and real GDP with the profitability of cooperatives, segment I, measured through the Return On Equity (ROE). Using econometric techniques, it is found that the country's production level and the generalized price level as external factors, maintain a statistically significant relationship with respect to the ROE of the cooperatives.","PeriodicalId":210068,"journal":{"name":"Studies of Applied Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117108267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Direct cash assistance is a social protection program from the government to maintain the ability to have purchasing power in meeting the needs of life. The subjects of this study were people who had livelihoods as farmers in various villages in Semen District, Gampengrejo District and Ngasem District, Donomulyo District, Sumbermanjing Wetan District, Wates District, and Binangun District, East Java Province, Indonesia. This type of research is explanatory and the data analysis method is carried out descriptively. The sampling method was carried out using a simple random sampling method on groups of farmer households in the village within the period of April-June 2021. Meanwhile, data collection is carried out by conducting in-depth interviews, observations, and distributing questionnaires. The number of samples that can be collected from data collection are 760 respondents. The results of the study provide results that the behavior of the digital economy of rural farmers is influenced by cost, privacy, and social factors. Direct cash assistance provided by the government to farmers encourages changes in farmers' behavior in conducting non-cash transactions. To encourage the digitization of non-cash transactions, it is necessary: the existence of digital literacy activities for farmers through the provision of IT supporting facilities and infrastructure, assistance in the use of IT in financial transactions, and, the existence of regulations that can facilitate farmers' access to digital financial transaction activities.","PeriodicalId":210068,"journal":{"name":"Studies of Applied Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128417268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Socially Responsible Investment (SRI) does not take into account this integration, so it is necessary to know the real impact that ESG criteria have on the valuation of actions to carry out effective investment decisions. The approach used is the Value – Drivers Adjustment (VDA) through the Discounted Cash Flow (DFC) method for Shell PLC as one of the most influential O&G companies in the energy transition. The results of the analysis reveal that the impact of ESG criteria on valuation translates into a reduction of 29.11% of its target price. The need for investment and the rising cost of capital explain these result. This results in a more comprehensive valuation method, where ESG criteria are no longer supplementary information and become indirect financial elements.\u0000 \u0000 ","PeriodicalId":210068,"journal":{"name":"Studies of Applied Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115983160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

That is why the fluctuation of oil prices and its impact on the general budget was chosen, and data were collected from the Central Bank, the Iraqi Ministry of Finance and OPEC, and the study is based on a review of the various literature presented in the paper.  For the purpose of the current study, the oil sector was chosen. The variables of exchange rate, gross domestic product, price per barrel, oil revenues, oil revenues, and inflation were measured with the help of data on a scale by using the multiple regression model. Indeed, the volatility of oil prices has been measured. The study concluded that there is an impact of oil price fluctuation on the general budget . The Iraqi economy loses more than one billion dollars due to the drop in crude oil prices by one dollar in the price of a barrel of oil it exports, which exacerbates its budget deficit.
