The literature on household behavior contains hardly any empirical research on the within-household distributional effects of tax-benefit policies. We simulate this effect in the framework of a collective model of labor supply when shifting from a joint to an individual taxation system in France. We show that the net-of-tax relative earning potential of the wife is a significant determinant of intrahousehold negotiation but with very low elasticity. Consequently, the labor supply responses to the reform are essentially driven by the traditional substitution and income effects as in a unitary model. For some households only, the reform alters the intrahousehold distribution in a way that tends to change normative conclusions. A sensitivity analysis shows that the distributional effects captured by the collective model would be significant only for reforms both radical and of extended scope.

Enterprise resource planning (ERP) is assumed as a commonly used solution in order to provide an integrated view of core business processes, including product planning, manufacturing cost, delivery, marketing, sales, inventory management, shipping and payment. Selection and implementation of a suitable ERP solution are not assumed a trivial project because of the challenging nature of it, high costs, long-duration of installation and customization, as well as lack of successful benchmarking experiences. During the ERP projects, several risk factors threat the successful implementation of the project. These risk factors usually refer to different phases of the ERP projects including purchasing, pilot implementation, teaching, install, synchronizing, and movement from old systems toward new ones, initiation and utilization. These risk factors have dominant effects on each other. The purpose of this paper is to explore the hybrid reliability-based method is proposed to assess the risk factors of ERP solutions.
In this regard, the most important risk factors of ERP solutions are first determined. Then, the interactive relations of these factors are recognized using a graph based method, called interpretive structural modeling. The resultant network of relations between these factors initiates a new viewpoint toward the cause and effect relations among risk factors. Afterwards, a fuzzy fault tree analysis is proposed to calculate Failure Fuzzy Possibility (FFP) for the basic events of the fault tree leading to a quantitative evaluation of risk factors.
The whole proposed method is applied in a well-known Iranian foodservice distributor as a case study. The most impressive risk factors are identified, classified and prioritized. Moreover, the cause and effect diagram between the risk factors are identified. So, the ERP leader can plan a low-risk project and increase the chance of success.
According to the authors’ best knowledge, such approach was not reported before in the literature of ERP risk assessments.

The Toyota Hilux case has been designed to show the complexities associated with managerial decision-making in a highly competitive vehicle market in South Africa. The case centres on the challenges the Toyota Hilux faced in sustaining its market leadership position amid intense competition from its rivals and changing customer preferences.
The case is suited to marketing and strategy students who are eager to demonstrate their critical thinking and managerial decision-making skills as part of their Masters of Business Administration (MBA) and Executive MBA academic programmes, and delegates on Executive Education programmes.
The teaching case focuses on the Toyota Hilux brand and the various business dilemmas that Calvyn Williams, sales and marketing manager, and his team experience prior to the launch of the next Hilux: the fierce competition from other brands and the various marketing strategies used.
Expected learning outcomes
The objective of this teaching case is to afford students a “hands-on” understanding and appreciation of the challenges faced by market leaders in sustaining their dominance and selecting the most appropriate strategies for market leaders to adopt in extremely competitive environments such as the South African vehicle market.

Through the use of both sight and blind‐based quality metrics, the purpose of this paper is to ascertain the extent to which the sighted appreciation of a wine's intrinsic merit is confounded by extrinsic cues such as price and region of origin.
Using a database of sighted and blind tastings of three red South African wines (Cabernet, Merlot and Shiraz) over the period 1993‐2001, a series of multiple linear regression models is developed to explain sighted quality ratings.
The meta‐model, with an adjusted R2 of 31 per cent, indicates three statistically significant explicatory factors, namely price, region, and intrinsic quality. The price cue alone explains 84 per cent of sighted quality assessments; the combined effect of both the region and price cue explains 95 per cent. This finding suggests that when quality is measured from a sighted perspective, area becomes a significant explicator, along with price. It is only once the cues of region and price have been factored into the meta‐model that intrinsic merit becomes relevant, and here, only to an extremely limited extent (5 per cent). The lack of correspondence between sighted and blind tasting scores, suggests that for sighted judgements – extrinsic cues appear to be masking the wine's intrinsic merit.
For the first time, blind and sighted tasting results are collated into one database and statistically interrogated. The findings show how we are deleteriously distracted by the apparent efficacy of extrinsic cues.

This study is concerned with evaluating the Federal Reserve forecasts of light motor vehicle sales. The goal is to assess accuracy gains from using consumer vehicle-buying attitudes and expectations about future business conditions derived from the long-running Michigan Surveys of Consumers.
Simplicity is a core principle in forecasting, and the literature provides plentiful evidence that combining forecasts from different methods and models reduces out-of-sample forecast errors if the methods and models are valid. As such, the authors construct a simple vector autoregressive (VAR) model that incorporates consumer vehicle-buying attitudes and expectations about future business conditions. Comparable forecasts of vehicle sales from this model are then combined with the Federal Reserve forecasts to assess accuracy gains.
The findings for 1994–2016 indicate that the Federal Reserve and VAR forecasts contain distinct and useful predictive information, and the combination of the two forecasts shows reductions in forecast errors that are more significant at longer horizons. The authors thus conclude that there are accuracy gains from using consumer survey responses.
This is the first study that is concerned with evaluating the Federal Reserve forecasts of vehicle sales and examines whether there are accuracy gains from using consumer vehicle-buying attitudes and expectations.

The rise of Emirates, Etihad, and Qatar Airways in the Middle East (collectively referred to as “ME3”) has been absolutely dramatic. How should other full-service carriers respond? This study takes a look at how one carrier, Singapore Airlines, has responded and may offer clues to how others may choose to respond. Facing ME3’s ascent in service quality and rapid capacity expansion, Singapore Airlines stuck to its niche as a premium carrier and refrained from tit-for-tat type competition. It managed to command a fare premium in select markets even in the presence of ME3, but had to sacrifice growth in its passenger count. This offers valuable lessons for other full-service carriers.

The purpose of this chapter is to describe and analyze the economic advantage of the geographical location of the Republic of Belarus. The current state of the Belarusian logistics system is analyzed in detail in the chapter. Thus effects of each direction of transportations are analyzed and also approaches to assessment of their cost efficiency are formulated. The factors influencing the export of transport services as well as the development of trends in the transport sector of Belarus are defined. The main directions and ways of improvement of logistics in the Republic of Belarus are described.
