The historic precedents in telecommunications antitrust findings have tended towards finding harm to competition when network operators integrate downstream and bundle the provision of applications and services. The reason for this is that market power in network provision is thought to be extended into the applications market(s). More recently however, proposed mergers have been between telecommunications and media distribution firms, both of whom have some degree of market power, already sell their own services in bundles, and who may or may not have been offering combined bundles already via contractual agreements. Examples include Sky/Vodafone in New Zealand, and Time Warner/AT&T in the United States as well as Vodafone/Unitymedia in Germany and Media Capital/Altice in Portugal. These complex proposed arrangements pose challenges to competition authorities, whose legal and procedural rules and precedents, especially those defining the relevant markets affected by the merger or vertical integration activity, have been developed from the analysis of simpler cases. These precedents may not be sufficient to analyse current cases, characterized by multiple products catering to heterogeneous consumer preferences, and consumers are not constrained to buying only one variant of the products in each of the upstream and downstream markets.We illustrate the challenges by way of a case study of the proposed merger between Sky and Vodafone, declined by the New Zealand Commerce Commission in February 2017. Limitations in existing market definition processes and the evaluation of market power where bundling already occurs risk overlooking complex demand-side interactions that influence the profitability and efficiency of various structural and contractual strategic choices. We propose that classic merger and antitrust analysis based on econometric cost-benefit analysis can be augmented by using simulation and numerical analysis of a range of bundle offers expected to be relevant in decision-making. We develop a simple model and use it to illustrate how it may be used to inform broadband and content mergers, and other complex antitrust cases, such the assessment of the effects of two-sided markets and firm pricing decisions.  相似文献

In 2014 democracy in South Africa was 20 years old. The democratic government in 1994 inherited both a high and increasing public debt/gross domestic product ratio and significant development backlogs. The government had to establish fiscal sustainability, yet also pursue development in a sustainable way. This article explores the government's performance in reconciling fiscal sustainability with sustainable development. The article shows that fiscal policy has been sustainable over the 20 years, with some risks appearing towards the end, and that the government pursued sustainable development through reallocating resources within the budget and by spending more in real terms. Three phases can be identified: 1994–2000, 2001–08 and 2009–13. However, poor service delivery and low levels of government investment during the 20 years threaten to undermine economic growth. Lower growth consequently threatens the sustainability of both fiscal policy and development, which, in turn, again undermines growth prospects. Hence, the article also identifies key future challenges.  相似文献

This paper investigates the expenditure patterns of South African households using detailed cross‐sectional expenditure and price data that varies across region and time. Linear expenditure system parameter estimates are used to calculate income and price elasticities for a number of product categories at different points of the income distribution. We find substantial variation in the price and income elasticities of demand for items across the income distribution, with the bottom quartile being extremely sensitive to increases in the price of food and clothing items, and the top quartile being as sensitive as households in developed countries.  相似文献

This research analyses the commitment to and use of ‘balanced scorecards’ by retailers in generating sustainable profitability, whilst contributing to socio-economic development in South Africa. An international literature review of scorecard frameworks, plans and reports by major retail companies and semi-structured dialogic interviews with a purposive sample of retail business stakeholders and government officials formed the methodology. By contrasting the literature and empirical insights, a summary of findings was generated, which conclude that most retailer scorecards (formal or informal) seek to balance financial with ‘cause-related marketing’ targets, but implementation differs according to factors such as company size, developmental maturity and managerial competence. Furthermore, collaboration between retailers and state institutions in scorecard management is not a reality, as has been achieved in other industries. It is therefore recommended that a Retail Charter scorecard framework be considered, to promote public/private-sector knowledge-sharing and socio-economic development.  相似文献

We explore international variation in business cycle dynamics to gain insights into the recent pattern of robust productivity growth during downturns (productive recessions) and weak employment growth during recoveries (jobless recoveries) seen in some advanced economies. We find that sectoral change is associated with productive recessions but that labor market rigidity can impede reallocation and reduce the probability of a productive recession. We also find evidence of a link between productive recessions and jobless recoveries and that recessions dominated by reductions to employment, rather than changes in average employee hours, are more likely to be associated with jobless recoveries.

The 1990s were an extraordinary period for the US economy, both because of declining budget deficits and emerging budget surpluses, as well as high rates of economic growth. This paper challenges the conventional wisdom that high growth rates caused budget improvements, and claims that budget consolidations also contributed to fostering economic growth. We propose the existence of a non-Keynesian effect, where fiscal policy runs counter to Keynesian theory and fiscal consolidation can foster economic growth. We present empirical evidence that an increase in tax revenues reduces the distortionary bias of future taxation and therefore leads to an increase in consumer confidence and consumption. Two supply side effects are proposed: a reduction in transfers reduced labour market pressures and government savings provided liquidity for financial markets, both of which increased incentives to invest.  相似文献

During the last decade economic literature explored the presence of and reasons for what became known as “the great moderation” in the US and other G7 countries. “The great moderation” describes the decrease in economic volatility experienced in many of the G7 countries. This paper finds that in South Africa volatility is also not constant (it even finds that there are autoregressive conditional heteroskedastic effects present) and that volatility also decreased, particularly since 1994. Following the literature, the paper explores several reasons for this decrease and finds that smaller shocks, better monetary policy and improvements in the financial sector that place less liquidity constraints on individuals and allow them to manage their debt better are some of the main reasons for the reduction in the volatility of the South African economy. The literature on the G7 also suggests that better inventory management contributed to the lower volatility. However, this seems not to be true for South Africa.  相似文献

Fields ( The Economic Journal , vol. 103, 1993, pp. 1228–35) provides a forceful argument in favor of a U-shaped path for inequality during a period of high-income-sector enlargement in a dual-economy model. This paper explores the assumptions necessary to derive Fields's controversial result and demonstrates that in fact a U-shaped pattern is possible using the Atkinson index, but some bizarre assumptions about inequality aversion are required.  相似文献
