Most-favored-nation (MFN) clauses in wholesale contracts have been the subject of recent controversy and renewed antitrust scrutiny. We demonstrate that a vertical environment where MFN clauses may be endogenously adopted shares equivalence properties with an environment where a final goods monopolist sells a good exhibiting negative consumption externalities directly to consumers and is faced with an exogenously imposed uniform pricing requirement. By leveraging these equivalence results, we are able to offer a new and useful framework for assessing the welfare effects of wholesale MFNs and which generates new insights.  相似文献

Between 1988 and 1993, the Belgian personal income tax system and the indirect tax system were reformed to a considerable extent. We use microsimulation models to investigate the impact of the reform on the liability progression and the redistributive effect of the combined tax system. The redistributive effect of personal income taxes decreased, notwithstanding an increase in liability progression. For indirect taxes, both the liability regressivity and the reverse redistributive effect have been enhanced. We use recently developed statistical tests to gauge the significance of the observed changes.  相似文献

This paper describes how the distribution of land access rights and the prevailing social fabric have evolved in a Rwandan village in the face of extreme land pressure. The study was conducted to gain a better understanding of the equity impact of land tenure individualization and the rising incidence of market transactions in such a context. The densely populated area studied during 1988-93 was in northwest Rwanda and belongs to the commune of Kanama in Gisenyi prefecture. Acute competition for land in a context characterized by too slow expansion of non-agricultural income opportunities has led to increasingly unequal land distribution and rapid processes of land dispossession through the functioning of the illegal land market and evolution of indigenous tenure arrangements. Also, the many land disputes and the threat of landlessness have led to rising tensions in social relations and even within the core of family life, paving the way for more overt expressions of discontentment and violence. A connection between those conditions and the civil war which erupted in 1994 is established.  相似文献

ABSTRACT

The complex nature of small business operations has led to adopting IT as a tool to enhance the productivity, efficiency and growth of Small, Medium and Micro Enterprise (SMMEs). Despite the increased spend on IT, many SMMEs do not understand the importance of IT investment evaluation, which adversely impacts their technology and decision-making ability to realise benefits. The study explores the role evaluation plays in SMMEs’ decision-making to adopt the technology, and the ability to evaluate technology potentials thereof. Case studies were conducted, data collected analysed using the thematic analysis, with hermeneutics employed to derive deeper and richer meanings from the findings. SMMEs often base their decision to adopt the technology on speculative and empirical knowledge from personal judgement, communication preferences and individual experiences. Implications of TE potential may lead to the adoption of inappropriate or non-adoption of the technology, with adverse effects on business sustainability.  相似文献

We present a qualitative study of Agile Stage-Gate Management (ASGM),: a hybrid new product development methodology that combines Agile and Stage-Gate Management (SGM) approaches for the coordination of new product development. When applied to software projects, Agile is expected to deliver reduced development times, improved resource utilization, and greater financial success. We examine whether ASGM practitioners realize similar outcomes in a sample of global firms developing complex electro-mechanical products (e.g., automobile components, railway propulsion systems, and medical devices). Our grounded theory approach articulates an understanding of ASGM through extensive interviews of experienced professionals. Our thematic analysis supports many expected benefits (i.e., speed to market, innovation enabling), but also does not encourage others, and reveals new pitfalls that deserve recognition (i.e., resource inefficiency). ASGM is not a panacea for all product development. Overall, physical product firms adopting this method can expect reduced development times and higher levels of innovation but will expend more resources to complete development projects, but a dichotomy exists. Physical product developers using ASGM experience a negative impact on project resource efficiency due to the need for dedicated resources, frequent product demonstrations, and duplicative management structures.  相似文献

We consider returns from rebalanced and buy and hold portfolios consisting of the same stocks. Theoretical properties are derived using Jensen’s inequality and the Hölder’s Defect Formula. Simulations are used to confirm theory and to investigate ambiguous cases where theory is silent. Rebalancing decreases total return volatility, while buy and hold produces greater expected return. Results are more opaque with respect to Sharpe Ratios and expected geometric means. Our empirical tests are based on portfolios composed of the risk-free asset, CRSP market value returns and returns from five Fama–French industries. While rebalancing reduces volatility and momentum effect, our tests largely favor the buy and hold strategy due to the high relative returns enjoyed by stocks vis-a-vis the risk-free asset. Transactions cost for rebalancing the portfolio are economically negligible.  相似文献

Based on the assumption that codified technological know-how contributes to economic growth, this paper presents the estimation of a Cobb–Douglas production function, pooling data from four European countries and 12 sectors. The empirical results confirm that both the stock of patents and the stock of technical standards contribute significantly to economic growth in the 1990s. Whereas the results of the country models are rather similar, we observe significant differences between the sector models, which indicate that standards are more important for growth in less R&D-intensive industries and patents in R&D-intensive industries.

The constant price method is used here to evaluate transfers related to inflation either between households and other economic agents (essentially enterprises) or among groups of households defined by occupation, age class and so on. The results obtained are only fragmentary due to a lack of many pieces of information. The method requires in fact the splitting up of every value variation into a price component and a size component.
Nevertheless, some interesting results are shown. In recent years, if the total productivity surplus has always been positive, the wealth surplus of households is sometimes positive, sometimes negative. Concerning the distribution of the productivity surplus among household groups, it has not been possible to find significant distortions, other than those which are related to differences in the propensity to save. On the contrary, marked distortions appear in the distribution of the wealth surplus due to wide differences in estate composition and indebtedness level.  相似文献

Multiple blockholder structures are a widespread phenomenon in the U.S. The theoretical literature, however, provides conflicting predictions on whether a single large blockholder or a set of dispersed smaller blockholders is better for firm value. Using U.S. data, we find a negative correlation between Tobin's Q and blockholder dispersion. The findings are robust to a wide variety of model specifications and controls and differ from results for other geographic regions such as Europe and Asia.  相似文献
