The purpose of this paper is to investigate the effects of tax reform on entrepreneurship in South Africa using repeated cross-sectional data from the World Bank.

The paper adopts a difference-in-difference estimation technique as well as contrasting periods before and after the tax reform. This contrast is achieved by examining individuals in the formal and informal sector and measuring the effectiveness of the reform on self-employment.

The results indicate that the tax reform had a positive and significant effect on the probability of becoming self-employed in South Africa and is robust across different econometric specifications.

The authors use individual-level data to measure the effectiveness of a tax reform policy on entrepreneurship. Utilizing the South African post-Apartheid tax reform as a natural experiment allows the authors to identify the effects of taxes on the choice of becoming self-employed.

Years ago, the Katz Commission questioned the constitutionality of certain provisions of the Income Tax Act, 1962. The purpose of this article is to investigate the general principles of human rights litigation and the progress made to date in respect of rectifying the unconstitutional provisions of the Income Tax Act that were identified by the Katz Commission. It has been established that, although some unconstitutional provisions have been amended, others still prevail, and that, in the light of the factors identified, they will probably not be challenged successfully by taxpayers.

In 1994, after the 1993 Constitution had been adopted, the Katz Commission questioned the constitutionality of some provisions of the Income Tax Act. The purpose of this article is, firstly, to follow up on the progress made in amending the provisions concerned and, secondly, to establish reasons for the lack of success achieved by taxpayers who attack the constitutionality of certain provisions. Some progress has been made, but in this article, the author argues that SARS should amend section 104(2) of the Act. The establishment of a specialist ombudsman’s office is also proposed. Such an office that could assist taxpayers to enforce their constitutional rights against the Commissioner is the essential missing element.

This study analyses and discusses the application and constitutionality of the general onus of proof provision (section 82 of the Income Tax Act 58 of 1962 [the “Act”]), the presumption in favour of the State when criminal sanctions are applied to an offending taxpayer (section 104(2) of the Act) and the mechanics for imposing administrative sanctions in terms of section 76(1)(b) of the Act. The conclusion reached is that the reverse onus presumption, as provided for in terms of section 104(2) of the Act, is unconstitutional. It is penal in nature and offends against the constitutional right of an accused to a fair trial (sections 35(3) of the Constitution of the Republic of South Africa Act, 108 of 1996 [the “Constitution”]). The section 36 limitation of rights clause of the Constitution does not save it. Section 76(1)(b) of the Act read in conjunction with the deeming provision of section 76(5) of the Act, is inextricably linked to the section 82 general reverse onus provision of the Act. Hence, when these three sections are applied together, they create a reverse onus that, prima facie, violates the right to just administrative action (section 33 of the Constitution). Regarding the general reverse onus burden as provided for in terms of section 82 of the Act, the conclusion reached is that it is reasonable and justifiable in an open and democratic society and can therefore be regarded as constitutional.

When products are differentiated, applying the standard critical loss formula to assess whether it is profitable for a hypothetical monopolist to impose a common price increase can lead to delineating an antitrust market that is too broad by setting a critical loss threshold that is too low. This error is particularly likely to occur when the products exhibit very different per-unit profits, own price elasticities, and cross price elasticities. In particular, different per-unit profits are a necessary condition for this error to occur and this difference is more likely to be driven by an asymmetry in prices than by an asymmetry in costs when own price elasticities are moderate in magnitude. In contrast, differences in the quantity sold of each product do not tend to lead to errors in market definition. Given the issues associated with the standard critical loss analysis, critical loss analysis with asymmetric price increases and the gross upward pricing pressure index are practical alternative approaches for conducting market definition analysis when products in a candidate market are differentiated.

A measure of how much money is laundered is required to determine the effectiveness of any anti-money laundering regime and the reduction of money laundering in targeted areas. In the absence of useful estimates, authorities need to look at the best quality data available to arrive at a meaningful estimate and a consequent target for reduction of money laundering. Since tax crimes are viewed as one of the top three sources of laundered money, an understanding of the underlying predicate offence – tax evasion – may be indicative of the values or volumes involved in order to facilitate a target setting process. It is suggested that a “whole of government approach”, as is advanced by the OECD, is applied between the tax administration and the financial intelligence centre in South Africa. The paper aims to discuss these issues.

By reviewing tax gap and money laundering estimation models and results from South Africa's first tax amnesty, it is proposed that micro analysis methodologies are applied to arrive at an estimate of the size and impact of money laundering which results from tax evasion practices.

By making basic inferences from the results of the 2003 voluntary disclosure programme, it is estimated that a potential revenue gap of between ZAR4 billion and ZAR12 billion exists for personal income tax alone and that the value of personal assets acquired from the proceeds of crime can, at any time, be as high as ZAR1.4 trillion.

In the absence of empirical and statistical data, it is necessary for authorities in developing countries to identify and make use of the most relevant and detailed data to assess its effectiveness in identifying, quantifying and reducing money laundering.

The purpose of this study is to use the structural model to determine the influence of mobile telecommunication on Egypt’s economic growth from 2000 to 2009. By focusing on mobile unique subscribers and mobile broadband-capable device penetration as indicators of telecommunications adoption, the authors seek to understand their overarching effects on the nation’s economic landscape.

The paper uses quarterly time-series data set over the period 2000–2019 and uses a structural econometric model based on an aggregate production function, a demand function, a supply function and an infrastructure function to detect causality and examine long-run relationships between variables.

The findings of the structural model reveal that both mobile unique subscribers and mobile broadband-capable device penetration significantly contributed to Egypt’s gross domestic product (GDP) growth from 2000 to 2019. Specifically, a 1% increase in mobile unique subscriber penetration and mobile broadband-capable device adoption is estimated to result in an average annual contribution to GDP growth of 0.172% and 0.016%, respectively.

The scarcity of panel data is the main research limitation for comparative study with other Middle East and North African Region (MENA) countries. Research extensions would include testing the significance of complementarities such as improving governance measures and building human capacity for both households and firms, which are necessary to boost the impact of telecommunication on economic growth in the MENA region.

Based on these findings, the study puts forth policy recommendations aimed at maximizing investment in network utilization, including mobile and internet services, as well as fixed broadband subscriptions. It highlights the crucial role of these investments in promoting social and economic development, not only in Egypt but also across the MENA region as a whole.

The findings of this research emphasize the importance of strategic investments in network utilization, encompassing mobile, internet services and fixed broadband subscriptions. Such investments are pivotal for fostering social and financial inclusion. The study underscores the potential of these investments to drive social and economic progress, not just within Egypt but throughout the entire MENA region.

Overall, existing literature generally supports the notion that the telecommunications sector has a positive economic impact. However, there is a gap in the literature when it comes to understanding the specific effects of the Egyptian telecommunications sector on the country’s economy, particularly in relation to the Egypt Vision 2030. The study aims to fill this gap by focusing specifically on Egypt and providing additional insights into the direct and indirect effects of the Egyptian telecommunications sector on the economy. By conducting a thorough analysis of the sector’s role, the authors aim to contribute to the existing literature by providing context-specific findings and recommendations.

Is the sharing economy a field? Answering this question is crucial to understanding how sharing organizations look and behave, as well as how the sharing economy might develop. In this chapter, the authors applied two different field conceptions – organizational field and issue field – as a starting point for an explorative empirical analysis. To capture both field concepts, the authors collected relational data and data on organizations’ self-representations to see how organizations engaged in the debate on the sharing economy relate to each other. The observed network of organizations suggests that the sharing economy is an issue field. In addition, the core of this network shows the relational structure of an organizational field. Surprisingly, it is not an organizational field of the sharing economy. Instead, it is a field of organizations heavily engaged in proselytizing new organizational forms that will change other fields. What the authors observed is a new field configuration – the authors call it a disruptive field – that is, less inward-oriented than other fields but much more engaged in changing other fields’ structures and dynamics. With these insights, the authors contribute to institutional research on field configuration and shed light on the phenomenon of the sharing economy and its potential development.

Public and private sector organisations are widely endorsing digital transformation processes, but little is known about the level of digitalisation of an organisation as a whole. The purpose of this paper is to develop a framework to assess an organisation’s level of digital transformation as a whole, taking the field of museums as an exemplary case of application.

The framework draws upon a scoping literature review of studies examining dimensions, metrics and methods for the assessment of the digital transformation of organisations. The framework has been validated by applying it to a sample of 400 Italian museums and further interviews with museum directors.

The authors propose an assessment framework composed of five main dimensions: people, technology, process, customer and strategy and investment. These dimensions are further deployed in sub-dimensions measured through a set of questions. The weighted average of results per dimension and sub-dimension supported the development of a composite index of organisational digital readiness.

The developed framework contributes to the current debate on the measurement of an organisation’s level of digital transformation as a whole, and it can offer practitioners a managerial tool to assess the organisation’s digital readiness.

The purpose of this paper is to consider the impact on bank risk of portfolio diversification between traditional margin income and fee‐based income for banks operating in Australia.

Considering several performance variables, this analysis compares the benefits of diversification across different bank types relative to margin income and fee income. Further, regression analysis considers bank risk and revenue concentration.

This paper documents that fee‐based income is riskier than margin income but offers diversification benefits to bank shareholders. While improving bank risk‐return tradeoff, these benefits are of second order importance compared to the large negative impact of poor asset quality on shareholder returns.

These results have implications for all stakeholders in Australian banks. The results suggest that shareholders of banks will benefit from increased bank exposure to non‐interest income via diversification. From a regulatory perspective, diversification reduces the possibility of systemic risk, but caution must be offered with respect to banks pursuing absolute returns rather than monitoring risk‐return trade‐offs, and so exploiting the benefits of the implied guarantee offered by “too big to fail” However, shareholders should also monitor bank exposure to non interest income to ensure that they do not become over‐exposed to the point where the volatility effect outweighs the diversification benefits.

The results of this study suggest that Australian regulators should consider requiring increased disclosure of the composition of bank non‐interest income. Such disclosure would aid in understanding the changing nature of banking in Australia. Given the recent sub‐prime crisis in the USA and the role played by fee based income sourced from securitization, increased disclosure of the nature of bank non interest income is now of global importance. This disclosure is particularly germane within the context of the implementation of Basle II, with its increased emphasis upon market discipline, given that Stiroh found increased disclosure in this area is accompanied by improved market pricing for risk.
