A consumer's post‐purchase product usage behaviour influences future decision making. Particularly, for fashion products, in which usage behaviour is highly observable, impacts of usage behaviour on future purchases and other consumers are more conspicuous. This study investigated usage behaviour for clothing fashion products. Behavioural aspects (use frequency and use variety) of usage behaviour were considered with psychological aspects (use satisfaction). The study focused on the differences in usage behaviour (use frequency, use variety and use satisfaction) by product types (fashionability and classification). Data was collected from a questionnaire survey. The results revealed that product types affected the post‐purchase usage behaviour of fashion products. There were significant differences in the use frequency by the product classification, in the use variety by the product fashionability and in the use satisfaction by the product classification and fashionability. Further, significant differences by product types were discussed.

This chapter considers warranty policies involving two attributes, such as the time elapsed since sale of the product and product usage at a given point in time. Examples of such policies are found for automobiles, where warranty may be invoked by the consumer if both time and usage are within specified warranty parameters when a product failure occurs. Here, we assume that usage and product age are related through a random variable, the usage rate, which may have a certain probabilistic distribution as influenced by consumer behavior patterns. Furthermore, product failure rate is influenced by the usage rate and product age as well as research and development expenditures per unit. It is assumed that, in production, there is a learning effect with time. The attained market share of a product will be influenced by the warranty policy parameters of warranty time and usage limit and also by the product price and product quality. An integrated model is developed to address multiobjective goals such as attainment of a specified level of market share and net profit per unit when manufacturing and warranty costs are taken into account. The impact of the goal priorities are investigated on the attained warranty policy parameters.

Two-attribute warranty policies are considered that incorporate, for example, the time elapsed since sale of the product and product usage at a given point in time. Such policies occur in consumer products, such as automobiles, where warranty may be exercised if both time and usage are within specified warranty parameters when a product failure occurs. In this chapter, it is assumed that usage and product age are related through a random variable, the usage rate, which may have a certain probabilistic distribution as influenced by consumer behavior patterns. Product quality is modeled through the product failure rate, which is influenced by unit research and development expenditures as well as the usage rate and product age. The attained market share of the product is modeled as a function of the warranty policy parameters of price, warranty time, and usage limit, with product quality also having an influence. Attainment of single and multiple objectives are explored. Such objectives encompass expected total unit costs as a proportion of unit product price and market share.

For certain consumer durables, such as automobiles, warranty policies involve two attributes. These could be the time elapsed since sale of the product and usage of the product at a given point in time. Warranty may be invoked by the consumer if both time and usage are within specified warranty parameters when a product failure occurs. In this chapter, we assume that usage and product age are related through a random variable, the usage rate, which may have a certain probabilistic distribution as influenced by consumer behavior patterns. Additionally, product failure rate is influenced by the usage rate and product age. The integrated model includes expected unit warranty costs, expected unit research and development costs, and expected unit production costs. It is assumed that in production, there is a learning effect with time. A multiobjective model is incorporated with the objectives being market share and proportion of expected warranty costs relative to total manufacturing expenditures per unit. The goals could be conflicting in nature. The problem then is to determine the warranty policy parameters while attaining certain desirable values of the two objectives.

Some consumer durables, such as automobiles, involve warranties involving two attributes. These are time elapsed since the sale of the product and the usage of the product at a given point in time. Warranty may be invoked by the customer if both time and usage are within the specified warranty parameters and product failure occurs. In this chapter, we assume that usage and product age are related through a random variable, the usage rate, which may have a certain probabilistic distribution as influenced by consumer behavior pattern. Further, product failure rate is influenced by the usage rate and product age. Of importance to the organization is to contain expected warranty costs and select appropriate values of the warranty parameters accordingly. An avenue to impact warranty costs is through research on product development. This has the potential to reduce the failure rate of the product. The objective then becomes to determine warranty parameters, while constraining the sum of the expected unit warranty costs and research and development (R&D) costs per unit sales, under a limited R&D budget.

The growing volume of consumer transactions in used products markets has given rise to strategic decisions made by sellers in the amount of information disclosed on usage‐based attributes – product attributes that quantify the degree by which a product has been used. This paper seeks to address this issue. Based on the phenomenon referred to as the dilution effect, it is proposed that sellers would have less desire to disclose usage‐based attribute information in product advertisements for older products. The effects of usage‐based attributes on asking prices of used products are also examined and profiled across time and contrasted across three countries: Britain, Canada, and the USA.

Used product advertisements were obtained for 1995 (USA) and 2010 (USA, Canada, and Britain). The ratio of ad content dedicated to usage‐based attributes was then computed and profiled across various conditions, and variations were tested using statistical methods.

The results indicate that a dilution‐based strategy, whereby usage‐based product information is less likely to be disclosed for older products, was evident in 1995 as it was in 2010. Furthermore, cross‐country variations were observed in the use of this strategy.

The research presented can be expanded to cover other product categories where used products are exchanged and usage‐based attributes constitute a fundamental consumer consideration in such exchanges. The research can also be extended to cover a wider range of countries for analysis.

This paper extends traditional pricing theory to consider the effects of usage‐based attributes on used product prices and associated consumer communications. Given the growth in the volume of consumer transactions in used product markets, this line of inquiry is relevant not only from an academic perspective but can also inform public policy and potential regulatory measures.

This study aims to identify the involuntary barriers of financial inclusion which are affecting the usage of Islamic microfinance services in PROCAPEC institution located in Nouakchott-Mauritania. Subsequently, it also examines the effect of gender as a moderator in the model.

Primary data was collected through a cross-sectional questionnaire from 381 beneficiaries of PROCAPEC – a major Islamic microfinance provider in Mauritania. In methodology, the study uses confirmatory factor analysis to identify relevant involuntary factors affecting usage, followed by structural equation modelling to test the impact of these factors on the usage of Islamic microfinance (IsMF) products.

Two of the four factors are statistically significant in affecting the usage of IsMF products, namely, affordability and eligibility. Gender is a moderator in the relationship between affordability and usage, as well as eligibility and usage.

Policymakers, practitioners and managers of Islamic microfinance institutions can consider these factors and focus on strategies, including pricing and promotion, which aim to further develop the Islamic microfinance industry in Mauritania. Also, reducing documentation required from clients and adopting lenient rules to provide suitable products will enhance the use of IsMF products, which may lead to more customers’ attraction.

Although several researchers have articulated financial inclusion, this study sheds light on a specific dimension of financial inclusion to determine the factors impacting IsMF products’ usage. In Mauritania, there are few studies about microfinance. This study will be amongst the pioneer contribution to the geographical gap.

Warranty policies for certain products, such as automobiles, often involve consideration of two attributes, for example, time and usage. Since consumers are not necessarily homogeneous in their use of the product, such policies provide protection to users of various categories. In this chapter, product usage at a certain time is linked to the product age through a variable defined as usage rate. This variable, usage rate, is assumed to be a random variable with a specified probability distribution, which permits modeling of a variety of customer categories. Another feature of the chapter is to model the propensity to execute the warranty, in the event of a failure within specified parameter values (say time or usage). In a competitive market, alternative product/warranty offerings may reduce the chances of exercising the warranty. This chapter investigates the impact of warranty policy parameters with the goal of maximizing market share, subject to certain constraints associated with expected warranty costs per unit not exceeding a desirable level.
