Customer Satisfaction with E-Retailers: The Role of Product Type in the Relative Importance of Attributes

It is of strategic importance for e-retailers to allocate their resources to various service attributes according to their relative importance. How does one determine the relative importance of different service attributes? Does the relative importance of different service attributes remain the same across different product categories? These questions must be addressed by researchers and e-retailers. Since customer ratings for service attributes are highly correlated, modeling methods other than traditional regression models should be used to analyze the relative importance of service attributes to overall customer satisfaction. As such, this article utilizes neural networks in order to study the relative importance of e-retailer service attributes. Importantly, this article shows that the relative importance of e-retailer service attributes varies across different product categories (i.e., convenience, shopping, and specialty goods).     

The Primitive Uncertainty Construct: Possibility,Potential Surprise,Probability and Belief; Some Experimental Evidence

This paper investigates the nature of the primitive uncertainty measure by means of a laboratory experiment that consists of four uncertain situations. It considers the related pair of possibility and potential surprise associated with George Shackle; and the supposedly related pair, belief and probability. The assessment of the relative merits of potential measures of uncertainty is based upon modal responses and χ² tests. It is found that the dominant uncertainty concept is potential surprise, and the subjects' explanations of their choice of an uncertainty concept gave substantial weight to possibility where it is felt that there is vagueness or doubt about the outcomes in a given situation     

Quantitative restrictions and Indian imports

Many governments in LDCs tend 3o rely heavily on import control for achieving adjustments in the balance of payments. The empirical analysis of imports of these countries has failed to address the issue of quantitative restrictions satisfactorily. In this paper, a set of disaggregated import demand equations are specified which attempt to capture the government's decision regarding quota restrictions. The model postulates that the overall level of imports is determined by expected foreign exchange availability while the composition of imports (once the level has been decided) is based on political and economic priorities and on relative prices.     

Global inequality and international trade

The paper analyses the effect of widespread trade liberalisationon global income inequality. The analysis of the trend in globalinequality during 1981–97, presented in the first partof the paper, shows that the apparent growth of income inequalityamong countries conceals a process of convergence. Some developingcountries achieved significantly faster economic growth thanthe advanced industrialised countries and, though small in number,they actually account for a majority of the population of thedeveloping world. Thus international inequality (i.e., the inequalityof distribution of per capita incomes among the world's population)in fact declined even though the inter-country income inequalityincreased. The analysis in the second part of the paper shows(i) that while improved trade performance did have a stimulatingeffect on growth performance of countries, trade liberalisationhad extremely varied effects on trade performance across countries,and (ii) that the distribution of benefits and costs of tradeliberalisation across countries has been such as to reduce internationalinequality without affecting inter-country inequality.     

Indebtedness,tenancy and the adoption of new technology in semi-feudal agriculture

The paper seeks to analyse the relationships between usurious money-lending, share tenancy and the incentives for the adoption of new technology by the semi-feudal landlords who typically combine the roles of landowner and money-lender vis-á-vis the tenants. It is argued that in a labour-abundant economy, ‘tenant-indebtedness’, by itself, is not likely to restrict the adoption of technological improvements. The adoption of new technology does not automatically improve the economic conditions of the tenants, nor does it necessarily transform the semi-feudal relations of production into capitalist ones.     

Personalized Pricing and Quality Customization

We embed the principal–agent model in a model of spatial differentiation with correlated consumer preferences to investigate the competitive implications of personalized pricing and quality allocation (PPQ), whereby duopoly firms charge different prices and offer different qualities to different consumers, based on their willingness to pay. Our model sheds light on the equilibrium product-line pricing and quality schedules offered by firms, given that none, one, or both firms implement PPQ. The adoption of PPQ has three effects in our model: it enables firms to extract higher rents from loyal customers, intensifies price competition for nonloyal customers, and eliminates cannibalization from customer self-selection. Contrary to prior literature on one-to-one marketing and price discrimination, we show that even symmetric firms can avoid the well-known Prisoner's Dilemma problem when they engage in personalized pricing and quality customization. When both firms have PPQ, consumer surplus is nonmonotonic in valuations such that some low-valuation consumers get higher surplus than high-valuation consumers. The adoption of PPQ can reduce information asymmetry, and therefore sellers offer higher-quality products after the adoption of PPQ. Overall, we find that while the simultaneous adoption of PPQ generally improves total social welfare and firm profits, it decreases total consumer surplus.     

Putting one-to-one marketing to work: Personalization, customization, and choice

The tailoring of a firm’s marketing mix to the individual customer is the essence of one-to-one marketing. In this paper, we distinguish between two forms of one-to-one marketing: personalization and customization. Personalization occurs when the firm decides what marketing mix is suitable for the individual. It is usually based on previously collected customer data. Customization occurs when the customer proactively specifies one or more elements of his or her marketing mix. We summarize key challenges and knowledge gaps in understanding both firm and customer choices in one-to-one markets. We conclude with a summary of research opportunities.     

A dimensional versus attribute approach for disaggregate choice models

A fundamental issue facing choice modelers is to make a decision on what kind of independent variables to include in a choice model. With survey data, the two immediate options are: actual product attributes or underlying latent dimensions (factor scores). Using behavioral logic we argue that heterogeneity of consumer perceptions of variables and their saliences should be the key items moderating such a decision. We present empirical evidence to support our theory that dimensional (factor score) based models do better in terms of predictions than attribute based models in more heterogeneous populations. Empirical analysis shows that in segments (where consumer heterogeneity is lower) the predictive performance of attribute based models improves relative to the factor score model and may actually have a better predictive fit when the respondents are relatively homogeneous with respect to attribute ratings and saliences.
