This paper shows the results of an exploratory analysis of the structure of a complex product category: Wine. In complex categories, a usual strategy of consumers is the partitioning of alternatives into homogeneous subsets and the sequential eliminations of subsets until a product/brand is chosen from among few homogeneous alternatives in the last subset. To identify if there is such a kind of strategy and the product attributes involved is of great interest for the retailer. After a discussion of the different modelling alternatives of the choice process, the authors provide an application of the additive trees (ADDTREE) model to explore the hierarchical structure. The ADDTREE results provide a first overview of the competitive market structure of the wine category: competition becomes more intense as the wine category is partitioned by, first, the type of wine criteria and, second, the designation of origin (DO) criteria. 相似文献

A major drawback of conventional models of the behavior of economic systems (and derived tools for policy intervention) is that the desire for tractability leads generally to a high degree of abstraction from reality. This article suggests an alternative, and arguably complementary, approach which engages specifically with economic complexity. The technique used is one of interactive spatial modelling over long time periods where the principle economic agents base decisions on incomplete heuristic information. For illustrative purposes the model has been calibrated on the basis of Senegalese data for 1981–91 and broad generic equations presented. The article argues that such a methodological approach holds out considerable advantages for strategic planning of sustainable economic systems. In particular it permits the direct engagement of noneconomic disciplines and client stakeholders in the planning process. 相似文献

We study the business‐cycle behavior of segmented labor markets with flexibility at the margin (e.g., just affecting fixed‐term contracts). We present a matching model with temporary and permanent jobs (i) where there is a gap in the firing costs associated with these types of jobs and (ii) where there are restrictions in the creation and duration of fixed‐term contracts. We show that a labor market with ``flexibility at the margin'' increases the unemployment volatility with respect to one that is fully regulated. This analysis yields new insights into the interpretation of the recent volatility changes witnessed in the OECD area. 相似文献

Consumer involvement in online shopping can play a moderating role when explaining Web site effect on satisfaction and trust. This study proposes a set of hypotheses based on the Elaboration Likelihood Model (ELM) of persuasion, a conceptual model that explains the formation of individual attitudes that are prompted by central and peripheral cues. The model proposes the use of central signals when the buyer is highly involved and peripheral signals when the buyer is less involved. Nevertheless, the results of this study would suggest that these relationships are not so clearly defined in the case of online buying, which implies that certain assumptions associated with the ELM need to be revised to take the particularities of the online context into account. © 2011 Wiley Periodicals, Inc. 相似文献

This study uses the strategic group theory to identify business strategies and competitive advantages implemented by Spanish hotels, which are grouped together according to three variables (size, chain affiliation, and category) and the degree of development of the different business strategies. An analysis carried out with the aim of checking the potential existence of significant differences in performance among the strategic groups revealed that the highest performance levels are achieved by larger-sized, chain-affiliated, and higher-category hotels as well as by establishments which base their competitive advantage on category and capacity or size and internal management. 相似文献

Self-regulation (SR) is a common way of enforcing quality in markets (such as banking, financial services and several professions) and in a variety of public and private organizations. We provide experimental evidence of the reputational incentives of self-regulatory organizations (SROs) to publicly disclose versus cover-up fraud in an incomplete information environment. We find that observed behaviour is generally consistent with Bayesian equilibrium when subjects are informed about the relative likelihood of fraud detection by a ‘vigilant’ versus a ‘lax’ SRO type. In particular, a fraud disclosure equilibrium is supported when subjects are informed that the ‘vigilant’ SRO is more likely to detect fraud; otherwise, a cover-up equilibrium is supported. However, when subjects are not informed about the relative likelihood of fraud detection by the SRO types (as expected in real SR situations), no equilibrium is strongly supported. Our results suggest that in practice, the reputation-based incentives for effective SR may be inherently ambiguous and weak. 相似文献

In this paper, we derive two-sided bounds for the ruin probability in the compound Poisson risk model when the adjustment coefficient of the individual claim size distribution does not exist. These bounds also apply directly to the tails of compound geometric distributions. The upper bound is tighter than that of Dickson (1994). The corresponding lower bound, which holds under the same conditions, is tighter than that of De Vylder and Goovaerts (1984). Even when the adjustment coefficient exists, the upper bound is, in some cases, tighter than Lundberg's bound. These bounds are applicable for any positive distribution function with a finite mean. Examples are given and numerical comparisons with asymptotic formulae for the ruin probability are also considered. 相似文献

Food price inflation in Brazil in the 12 months to June 2008 was 18%, whereas overall inflation was 7%. Using spatially disaggregated monthly data on consumer prices and two different household surveys, we estimate the welfare consequences of these food price increases, and their distribution across households. Because Brazil is a large food producer, with a predominantly wage‐earning agricultural labour force, our estimates include general equilibrium effects on market and transfer incomes, as well as the standard estimates of changes in consumer surplus. Although the expenditure (or consumer surplus) effects were large, negative and markedly regressive everywhere, estimates of the market‐income effect were positive and progressive, particularly in rural areas. Because of this effect on the rural poor, and of the partial protection afforded by increases in two large social assistance benefits, the overall impact of higher food prices in Brazil was U‐shaped, with middle‐income groups suffering larger proportional losses than the very poor. Nevertheless, as Brazil is 80% urban, higher food prices still led to a greater incidence and depth of poverty at the national level. 相似文献

This article presents an application of a bibliometric and visual study of the research carried out on a social science subfield,
concretely the consumer behaviour research (CBR), from a longitudinal perspective (period 1966–2008). The study combines performance
analysis and science mapping for detecting and visualizing conceptual subdomains. Quantitative and qualitative measures are
used in order to identify the most prominent themes. Quantitative data are used to put together very related concepts (themes
or clusters of topics), while qualitative indicators (as those based on citations) are used to measure the quality and/or
impact of the detected themes. The study also uses bibliometric maps to show in a visual way the associations between the
main concepts treated by the CBR community. The maps provide insight into the structure of the CBR, visualize the division
of the field into several subfields, and indicate the relationships between these subfields. Co-word analysis is the bibliometric
technique used to identify the main themes. All this allows us to quantify and visualize the thematic evolution of the CBR.
It also helps to both experts and novices to understand the current state of the art of the CBR and to predict where future
research could lead. 相似文献
