Analyzing the impact of GST on tax revenue in India : the tax buoyancy approach

Purpose: The purpose of this paper is to analyse the impact of newly introduced Goods and Services Tax (GST) in India. This paper adopts the tax buoyancy approach for analysing the impact of GST on tax revenue. Design/Methodology/Approach: We conducted our study using semi logarithmic ANCOVA regression model in which we introduced VAT and GST as dummy variables. Findings: Our study finds that after the introduction of GST India’s tax revenue has become less responsive to the changes in GDP. It indicates that post introduction of GST there is some reduction in the tax burden on the consumers and corporates which supports the government’s justification behind the introduction of GST. Practical Implications: The study is expected to help the government in deciding the future course of action towards effective policy making for revenue generation. Originality/Value: Since none of the existing studies analyses the impact of GST on tax revenue our study is unique and fulfils the gap in the existing literature.peer-reviewe

Proxy Signature Scheme with Effective Revocation Using Bilinear Pairings

We present a proxy signature scheme using bilinear pairings that provides effective proxy revocation. The scheme uses a binding-blinding technique to avoid secure channel requirements in the key issuance stage. With this technique, the signer receives a partial private key from a trusted authority and unblinds it to get his private key, in turn, overcomes the key escrow problem which is a constraint in most of the pairing-based proxy signature schemes. The scheme fulfills the necessary security requirements of proxy signature and resists other possible threats

Cryptanalysis of recently proposed Remote User Authentication Schemes

Recently Manik et al. [13] proposed a novel remote user authentication scheme using bilinear pairings. Chou et al. [14] identified a weakness in Manik et al.’s scheme and made an improvement. In this paper, we show that both Manik et al.’s and Chou et al.’s schemes are insecure against forgery attack and replay attack

Computer extracted gland features from H&E predicts prostate cancer recurrence comparably to a genomic companion diagnostic test: a large multi-site study

Existing tools for post-radical prostatectomy (RP) prostate cancer biochemical recurrence (BCR) prognosis rely on human pathologist-derived parameters such as tumor grade, with the resulting inter-reviewer variability. Genomic companion diagnostic tests such as Decipher tend to be tissue destructive, expensive, and not routinely available in most centers. We present a tissue non-destructive method for automated BCR prognosis, termed "Histotyping", that employs computational image analysis of morphologic patterns of prostate tissue from a single, routinely acquired hematoxylin and eosin slide. Patients from two institutions (n = 214) were used to train Histotyping for identifying high-risk patients based on six features of glandular morphology extracted from RP specimens. Histotyping was validated for post-RP BCR prognosis on a separate set of n = 675 patients from five institutions and compared against Decipher on n = 167 patients. Histotyping was prognostic of BCR in the validation set (p < 0.001, univariable hazard ratio [HR] = 2.83, 95% confidence interval [CI]: 2.03-3.93, concordance index [c-index] = 0.68, median years-to-BCR: 1.7). Histotyping was also prognostic in clinically stratified subsets, such as patients with Gleason grade group 3 (HR = 4.09) and negative surgical margins (HR = 3.26). Histotyping was prognostic independent of grade group, margin status, pathological stage, and preoperative prostate-specific antigen (PSA) (multivariable p < 0.001, HR = 2.09, 95% CI: 1.40-3.10, n = 648). The combination of Histotyping, grade group, and preoperative PSA outperformed Decipher (c-index = 0.75 vs. 0.70, n = 167). These results suggest that a prognostic classifier for prostate cancer based on digital images could serve as an alternative or complement to molecular-based companion diagnostic tests

The Effects of Internal Audit, Audit Committee and Firm Characteristics on Audit Fees in a Multi-Country and Industry Setting

This paper examines the association between audit fees and attributes of internal audit (IA), audit committee (AC), as measured by independence and financial expertise, as well as characteristics of the firm. The determinants of audit fees have been extensively investigated in the prior literature, but the results are conflicting. We develop a comprehensive model from a multi-country and multi-industry perspective. A total of 3,136 companies covering a period of 10 years (2011-2020) with 15,247 observations from 55 countries were included in this study. We found that the most critical variables that have a significant positive effect on the audit fees are client size, leverage (risk), profitability, complexity, losses, AC independence, AC expertise and auditor size. The study also shows that audit pricing is significantly negatively related to foreign operations, auditor tenure, and internal audit independence. The results highlight variables that affect audit fees across a range of countries/industries

An empirical analysis of auditors' evidence gathering techniques in Bahrain

This study investigates auditors' perceptions regarding audit evidence gathering techniques in the following areas: extent of use, reliability, average time spent and persuasiveness of the collected evidence. Additionally, the problems encountered by the auditors in using these techniques in the field are also catalogued. This study used a survey method and collected information from the Big 4 and non-Big 4 firms in Bahrain. The results indicate that the auditors primarily use documentation, analytical procedures and confirmations in collecting evidence. The auditors rank confirmation, physical and documentary evidence as the most reliable forms of evidence. The auditors also spend most of their time on these techniques. However, the sufficiency and competency of the audit evidence is rated as merely satisfactory. The Bahrain business environment is conservative and secretive, which affects the audit process and partly explains our results. The common problems faced by both the Big 4 and non-Big 4 firms are difficulties in collecting external evidence and uncooperative clients. The study also analyses the differences in the perceptions of the Big 4 and non-Big 4 auditors and experienced versus non-experienced auditors. The results of this study shed light on the problems and perception of the auditors in the non-Western countries in using standard evidence collection techniques.audit evidence; Bahrain; Big 4 firms; non-Big 4 firms; evidence persuasiveness; auditor perceptions; auditing; reliability; evidence collection.

Point‐of‐care end‐tidal carbon monoxide reflects severity of hemolysis in sickle cell anemia

Carbon monoxide (CO) production from heme catabolism is increased with hemolysis. A portable end-tidal CO (ETCO) monitor was used to analyze breath samples in 16 children with sickle cell anemia (SCA, 5-14 years). Median (range) ETCO for SCA was 4.35 ppm (1.8-9.7) versus 0.80 ppm (0.2-2.3) for controls (P &lt; 0.001). ETCOc &gt;2.1 ppm provided sensitivity and specificity of 93.8% (69.8-99.8%) for detecting SCA. ETCO correlated with reticulocytosis (P = 0.015) and bilirubin (P = 0.009), and was 32% lower in children receiving hydroxyurea (P = 0.09). Point-of-care ETCO analysis may prove useful for non-invasive monitoring of hemolysis and as a screening test for SCA
