Abstract

This study aimed to estimate the extent of tax evasion in Jordan based on a currency demand methodology, the results of the time series stationarity test showed that there was a time series to be non-stationary at the same degree, and the results of the co-integration test showed the existence of co-integration between the model variables, the size of tax evasion during the period 1980–2019 was estimated using the fully modified ordinary least squares method (FM-OLS).The results showed that the average rate of tax evasion as a percentage of (GDP) amounted to 2.7%, whereas it reached 16.7% of tax revenues, After the extent of tax evasion had been estimated, its impact on some macroeconomic variables was identified through the Toda and Yamamoto causality test, This test showed that tax evasion had an impact on the general consumer price index, GDP, tax revenues, public debt, both public and private investment, and both public and private consumption, Finally the study recommends that more attention should be paid to the tax evasion phenomenon by officials in charge of economic policies and tax administration in order to reduce tax evasion and its impact on the economic variables and, thus, achieve greater economic stability. Doi: 10.28991/esj-2021-01271 Full Text: PDF

Abstract

In the modern era, many research works are going on throughout the world for finding suitable cementitious material for the replacement of cement since it causes environmental pollution. In this order Fly ash, Silica fume, GGBS, Metakaolin, Micro materials, Quartz powder, etc. are tried out for replacing partially or fully the cement in concrete. A new ultrafine material called Alccofine (AF) which is manufactured from glass wastes is tried out for replacing partially in this research. Compressive strength is one of the important properties of cement. Strength tests are not made on neat cement paste because of difficulties of excessive shrinkage and subsequent cracking of neat cement. Cement mortar of 1:3 mix proportion is used to cast the cubes having an area of 50 cm2 are used for the determination of compressive strength of cement as per IS: 4031-1988 (Part-6). The graded Indian Standard sand (Ennore Sand -ES) confirming to IS: 650-1991 is used for preparing the cubes. In the same mix proportion, the same size cubes are cast with the River Sand (RS) to study the difference of the compressive strength between the Indian standard sand and river sand. Ordinary Portland cement (OPC) and Portland Pozzolana Cements (PPC) are used. The present study is the influence of Alccofine on cement mortar cubes by replacing the cement by Alccofine with various proportions like 5%, 10%, 15%, 20% were cast and tested in the laboratory as per Indian Standard 4301-1988 (Part-6) and the results were analysed and presented in the form of charts and graphs. It is observed that the early age strength is obtained for all the combinations but 10 percent of Alccofine yields more strength than other dosages. Doi: 10.28991/esj-2021-01265 Full Text: PDF
