The main objective of this study is to propose an appropriate time series forecasting model for HIBOR. HIBOR conceptually captures the interaction between demand and supply of Hong Kong dollar in the interbank market. The volatility of HIBOR reflects market sentiment, changes in underlying macroeconomic environment, random events and even political climate. Thus, the time series data of HIBOR appears to have multiple seasonality during the aforesaid period. The TBATS model, the state space modeling framework developed by De Livera, Hyndman and Snyder (2010) is adopted for this study to improve the accuracy and efficiency of the time series modeling and forecasting of HIBOR. The TBATS model incorporates Box-Cox transformations, Fourier representations with time varying coefficients, and ARMA error correction. Likelihood evaluation and analytical expressions for point forecasts and interval predictions under the assumption of Gaussian errors are derived, leading to a simple, comprehensive approach to forecasting complex seasonal time series. In addition, the trigonometric formulation is used as a means of decomposing complex seasonal time series, which helps to identify and extract seasonal components which are otherwise not apparent in the time series plot itself. The performance of the TBATS model as evaluated by measures of forecast error are presented.","PeriodicalId":70909,"journal":{"name":"经济世界:英文版","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135778085","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}

The goal is the complete modernization of the tax system, so that it responds more fully to the principles of social justice, contributes to the economic development of the country and is governed by simple and modern procedures, which apply to all tax objects. The purpose of the study is to deepen the proposals for tax reform based on the peculiarities of the Greek economy, the international trends in this field and the weaknesses of the tax system. The effects of a tax reformation are analyzed and how it should take the form of the reform, which, however, requires a new legislation, which will bring about radical and deep cuts, which respond to the new conditions and the internationalization of the economy. Proposals for a set of structural measures, which are necessary for the country’s adaptation to the wider European environment and the elimination of the weaknesses that increase its distance from the other member countries.
