The purpose of this study is to study the impact of chosen macroeconomic factors on firm performance in the United Kingdom. To study effects of macroeconomic factors, panel data with instrumental variables were used between the period of 2000 and 2014 for top 100 firms in UK. As a result of the analysis, gross domestic product, inflation rate, and the rate of domestic debt interest payments to total income tax have a direct impact on firm performance. On the other hand, exchange rate, interest rate and the rate of short term foreign debts to central bank international reserves have an inverse relationship. 2018-01-01T00:00:00Z /library/oar/handle/123456789/73110 Title: An investigation of fat-tailed distributions in fitting the Japanese stock market returns Authors: Kayaba, Kengo; Hirano, Yui; Ueda, Naoki; Matsui, Nobuki Abstract: The Tokyo Stock Exchange (TSE) is the fourth largest stock exchange in the world by aggregate market capitalization of its listed companies and largest in East Asia and Asia. It is of great importance for those in charge of managing risk to understand how its market index returns are distributed. The goal of this paper is to examine how various types of heavy-tailed distribution perform in risk management of the N225 Index returns. We compared these heavy-tailed distributions through a variety of criteria. Our results indicate the generalized hyperbolic distribution has the best goodness of fit and generates most suitable risk measures. 2018-01-01T00:00:00Z /library/oar/handle/123456789/73109 Title: The challenges and countermeasures of blockchain finance and economics Authors: Zheng, Yang; Huang, Tao Abstract: Blockchain is a new underlying technology in the Internet era, whose ultimate goal is to analyse and process the information data through the effective integration of financial resources. No matter what kind of financial formats or new financial service models are generated, they are all dedicated to upgrade the financial system and promote the efficiency and quality of financial operations and service from the layer of data, rules, and application according to the market and customer needs. Blockchain technology can help the financial industry to automatically and accurately identify customer credit conditions to restructure the financial market credit system and improve the efficiency of cross-border payment. However, it also poses a challenge for the development of the financial industries. In this paper, we systematically analyse the technology of blockchain and its application in the financial and economic field, the status quo and the challenges it faces, and then give constructive suggestions to help the blockchain technology develop better in the financial and economic field. 2018-01-01T00:00:00Z /library/oar/handle/123456789/73108 Title: Competing globally with cost accounting : a case study Authors: Pedro, Maria Isabel; Cancio Martins, Joao; Filipe, José António Abstract: In recent years, information has played a key role in business competitiveness, allowing not only to inform managers about external contexts, but also to internal problems. Thus, cost accounting has relevant tools, with the ability to provide information about how the resources of a company are used, making it possible to evaluate and improve their performance. The main goal of this research is to develop a different costing system model to a company, in order to provide distinct information on the costs of production processes, to help managers make better operational and strategic decisions. This company business is processing and packaging fruit and vegetables, in particular they are organized by three main sectors: fruit, potatoes and 4th range products. Those cost allocation methodologies could be identified, on one hand, the profitability of each product, helping to define the best medium-term strategy and, on the other hand, some operational faults. Basically, this work aims to prove the importance of costing models to improve the performance and the competitiveness in a real context. 2018-01-01T00:00:00Z
