Estimating demand with distance functions: Parameterization in the primal and dual

Our purpose is to investigate the ability of different parametric forms to ‘correctly’ estimate consumer demands based on distance functions using Monte Carlo methods. Our approach combines economic theory, econometrics and quadratic approximation. We begin by deriving parameterizations for transformed quadratic functions which are linear in parameters and characterized by either homogeneity or which satisfy the translation property. Homogeneity is typical of Shephard distance functions and expenditure functions, whereas translation is characteristic of benefit/shortage or directional distance functions. The functional forms which satisfy these conditions and include both first- and second-order terms are the translog and quadratic forms, respectively. We then derive a primal characterization which is homogeneous and parameterized as translog and a dual model which satisfies the translation property and is specified as quadratic. We assess functional form performance by focusing on empirical violations of the regularity conditions. Our analysis corroborates results from earlier Monte Carlo studies on the production side suggesting that the quadratic form more closely approximates the ‘true’ technology or in our context consumer preferences than the translog.     

The meeting place: Qualitative aspects of product environmental assessment

Quantitative methods for evaluating the environmental impact of products are receiving considerable attention. Software is being developed to enable analysis of many aspects of a product's life cycle—from materials' extraction, through manufacture, to use and disposal. Less attention is being paid to the qualitative aspects of products and their significance in addressing environmental concerns. Here, the argument is made for including qualitative evaluations as an important facet of product environment assessment. Such evaluations are essential if significant progress is to be made in alleviating the adverse environmental effects of products. Combined with quantitative analyses, the two approaches become mutually supportive and, ultimately, inseparable.Qualitative environmental assessments can be applied to existing products and at every stage of the design process. Their adoption within the context of professional practice will be fostered by their inclusion, formulation and discussion within design education. This paper describes the basis and nature of these qualitative judgments, and places the qualitative and quantitative in a unified context which points towards more sustainable ways of living. The use of scenarios is discussed as a tool for academic design projects in order to address the complex relationships which might otherwise seem overwhelming to the design student.

British Science Parks: Reflections on the Politics of High Technology

Science parks—high technology property developments associated with universities—have suddenly proliferated in Britain. Local authorities, universities and public sector development agencies are now eager to exploit what seems an obvious way of stimulating high technology industry. Though much of their enthusiasm is a product of self interest, it is justified by arguments that science parks provide conditions conducive to high technology industry's prosperity. These arguments are hard to accept, but then so too is the reasoning that perceives easy and instant benefits from high technology. Such euphoria is in stark contrast to the reality that will probably face many British science parks. Keywords: science parks, high technology, universities, Britain, information flow.     

Transparency and empowerment in an investment environment

In a laboratory-controlled environment we provide experimental evidence on the effects of transparency (complete over incomplete information) and empowerment on trust and trustworthiness. We implement a simple version of the standard two-person investment game in a repeated game context with multiple treatments under two information environments. We find that when principals are empowered by being able to penalize agents who may not act in a way the principal believes is in the principal's best interest, the level of trust and investment increases over that which is realized in the absence of empowerment regardless of the degree of transparency. In transparent environments the effect of empowerment is about the same regardless of whether empowerment is introduced or removed. However, in opaque environments, the loss of empowerment has a substantially greater negative effect on trust than the positive effect associated with the introduction of empowerment.     

The effect of traditionally marginalized groups in advertising on consumer response

Increasingly, national brands have cast people from marginalized groups in advertising. It is important to understand the elements that influence consumers’ responses to advertisements featuring groups who have been traditionally excluded from advertising campaigns. Although consumers may wish to buy brands that support their own views on human rights and equality, we propose that consumers in the target market may be uncomfortable if the group portrayal contradicts their beliefs about the topic, concept, or social groups in the ad. Across two studies, we show that when an ad creates this type of internal contradiction within consumers, it may elicit a more negative response than an ad portraying a more traditional model. However, we also find preliminary evidence that using models from marginalized groups can be more effective than using more traditional models—as long as such portrayals do not violate certain target consumers’ schemas. The implications of these results will be discussed.     

Online marketing: When to offer a refund for advanced sales

Advance selling is a marketing strategy commonly used by online retailers to increase sales by exploiting consumer valuation uncertainty. Recently, some online retailers have started to allow refunds on products sold in advance. On the one hand this reduces the net advance sales, but on the other hand it allows a higher advance sales price. This research is the first to explore the overall effect of allowing a refund on profits from advance sales, identifying conditions where advance selling with or without refunds (or no advance selling at all) is best. We analytically compare the profits of three advance selling strategies: none, without refund, and with refund. We show that selling in advance and allowing a refund is optimal for products with a relatively small profit margin and small strategic market size, and that the added profit can be considerable. Our results guide managers in selecting the right advance selling strategy. To facilitate this, we graphically display, based on the two dimensions of regular profit margin and strategic market size, under what conditions the different strategies are optimal.     

A modest proposal for resolving the Eurozone crisis

This paper presents three simple policies for overcoming the crisis that can be implemented immediately and require none of the moves such as national guarantees or fiscal transfers to which many Europeans are opposed, nor moves towards federation that entail Treaty changes, which electorates are most likely to reject. The logic behind these policy proposals is juxtaposed with the false dilemmas that currently impede clear thinking and immobilise Europe’s policymakers.     

Keiretsu centrality — profits and profit stability: A power dependence perspective

Prior studies compare keiretsu member firm and independent firm performance. Here, we use historical and power dependence perspectives to theorize that the Japanese keiretsu system primarily benefits the most central firms. We test this by examining the performance of two types of keiretsu firms (central firms and other member firms) within two types of keiretsu (horizontal and vertical). We hypothesize and find that: (1) central vertical keiretsu firms are more profitable than central horizontal keiretsu firms; (2) central horizontal keiretsu firms have greater profit stability than central vertical keiretsu firms; (3) central vertical keiretsu firms are more profitable than non-central vertical keiretsu firms; and (4) central horizontal keiretsu firms have greater profit stability than non-central horizontal keiretsu firms. Implications for managers and future research directions are discussed.
