The purpose of this paper is to test whether the IKEA-effect (Norton et al., 2012) – better liking for self-crafted products than for identical products crafted by others – can be exploited to increase liking and consumption of vegetable snacks in children.

A between-subjects experiment was conducted at an after school care facility. In total, 86 children aged four to six either crafted a peacock with vegetables or with non-food objects following an example. After the task, children ate snack vegetables ad libitum, and rated their liking for the vegetables and pride in crafting the peacock.

No significant main effect of the vegetable snack creation on consumption and liking was observed. Also, perceived pride did not mediate the effect of self-crafting vegetable snacks on consumption of and liking for vegetables.

Vegetable consumption did not differ between children who were either simply exposed to vegetable snacks while crafting or those who were crafting the vegetable snacks themselves. The equal consumption might suggest that this is caused by simple exposure, but more research is needed comparing self-crafting and exposure to a condition where there is no initial exposure to vegetables.

Although the IKEA-effect has been demonstrated in adults, this is one of the first studies evaluating the IKEA-effect in children and as a means to increase liking for a generally disliked product in this target group, i.e. vegetables. The IKEA-effect could not be replicated under these more stringent conditions, where the experimental set-up enabled disentangling exposure and crafting effects.

What if companies try to combine the IKEA and Trophy winner effects? The purpose of this study is to understand the similarities and differences between both effects. This is not only theoretically but also practically important for the way that companies interact with their customers.

Successful work – invested either to create or to obtain a product – increases the customers’ valuation of the product. This phenomenon known as the IKEA or Trophy winner effect. This study directly compares both effects using experiments with two different products (paper planes and 3D puzzles). Moreover, this study tests whether they reinforce each other.

The Trophy winner effect looms larger than the IKEA effect for inexpensive items. For slightly more expensive products, this study finds a Trophy loser effect. Positive emotions of trophy winners drive the results for inexpensive products, whereas negative emotions of trophy losers drive the results for slightly more expensive products.

The relevance of the IKEA and Trophy effects is influenced by the type of product. Customers’ labor invested in the product itself is of greater importance the more expensive the product is. As soon as customers interpret the interaction with other customers as competition, the effect on valuation can be substantial even for inexpensive products. Future studies could try to replicate our results with different product categories.

Although the IKEA and Trophy effects are no new phenomena in consumer psychology and behavioral economics, they have not been compared to each other or combined yet. The results are useful for researchers and practitioners alike. They yield implications for product customization and customer empowerment.

This study aims to understand the underlying mechanism and boundary conditions of the IKEA effect in self-expressive mass customization (MC). It examines the effect of the extent of choice in MC toolkits in terms of perceived value of self-designed products, as well as how self-expression mediates this effect and what kind of consumers are more inclined to experience such effect.

Two experiments were conducted, using online MC toolkits. In total, 393 consumers participated in the experiments. Data collected were analyzed using t-tests, analyses of variance, path analyses, bootstrap analyses and spotlight tests.

The results show that offering a greater extent of choice in MC toolkits to consumers provides a greater opportunity for self-expression, resulting in higher product valuation. Further, consumers who have high romanticism in aesthetic preference and high self-esteem are more inclined to influences associated with this effect.

This research adds to the literature on the IKEA effect in self-expressive MC by identifying a key antecedent (extent of choice), its underlying mechanism (self-expression), and two boundary conditions (aesthetic preference and self-esteem). The results of this study provide firms with a better understanding of how they can improve their self-expressive MC strategies.

This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies.

Falling in love with one’s own product is not rational behavior and could be misleading, as it blinds people to strategic foresight. Products should be designed with a strategic focus that is both innovation- and customer-centric.

The paper provides strategic insights and practical thinking that have influenced some of the world’s leading organizations.

The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

The purpose of this paper is to contribute to the marketing literature and practice by examining the effect of product pricing on consumer behaviours with regard to the assertiveness and the sentiments expressed in their product reviews. In addition, the paper uses new data collection and machine learning tools that can also be extended for other research of online consumer reviewing behaviours.

Using web crawling techniques, a large data set was extracted from the Google Play Store. Following this, the authors created machine learning algorithms to identify topics from product reviews and to quantify assertiveness and sentiments from the review texts.

The results indicate that product pricing models affect consumer review sentiment, assertiveness and topics. Removing upfront payment obligations positively impacts the overall and pricing specific consumer sentiment and reduces assertiveness.

The results reveal new effects of pricing models on the nature of consumer reviews of products and form a basis for future research. The study was conducted in the gaming category of the Google Play Store and the generalisability of the findings for other app segments or marketplaces should be further tested.

The findings can help companies that create digital products in choosing a pricing strategy for their apps. The paper is the first to investigate how pricing modes affect the nature of online reviews written by consumers.

The purpose of this paper is to assess the effect of involvement in food preparation on estimated calorie content, perception of portion size and desirability of the food item.

To test the hypotheses, three between-subjects experiments (one online, two in a laboratory setting) were conducted. Across the three experiments, participants were presented with a food item either ready for consumption (low involvement) or with the individual ingredients in need of assembly prior to consumption (high involvement).

Results showed that when a consumer is involved in the preparation of their food, they perceive the food to be lower in calories and smaller in portion size than when the same food is presented fully prepared and ready-to-eat. In addition, the effect of food preparation involvement on perception of portion size has negative downstream consequences on food desirability, as a smaller perceived portion resulted in a less desirable food item.

To the authors’ knowledge, the results of this research are the first to focus on the impact of preparation involvement on perceptions of the specific product attributes of calorie content and portion size, and the downstream effect on desirability.

The purpose of this paper is to examine the effect of manufacturers’ co-production strategy on market segmentation and channel performance under retail competition.

It differs from previous empirical studies by primarily focusing on the increment in consumer value accompanying co-production. The authors establish a game-theoretical model to analyze the impact of co-production on market segmentation and the profitability of channel members in a competitive retail environment.

The results reveal that manufacturers introducing co-production expand market coverage and benefit all channel members, when the intensity of competition is sufficiently high, especially for retailers with low-quality levels, who are out of the market without co-production. Furthermore, with the increase in customer valuation through co-production, employing a co-production strategy is always a dominant strategy for manufacturers.

First, although the authors assume a monopoly manufacturer and two duopoly retailers, adding competition between manufacturers should enrich the model. Multiple products with vertical or horizontal differentiation could also be introduced into the model. Second, the authors use the multiplicative utility function to model the value co-creation effect on consumers; however, different utility functions may yield significantly different results and implications. Third, the authors model a one-shot game in a single product selling period; future studies may employ multi-period games to obtain further insight into co-production strategy. Finally, the model assumes that all consumers are homogenous in the extent of value creation and hassle cost. Future research may find it interesting to consider heterogeneity in these characteristics.

The business world today already sees the power of leadership in a supply chain to have shifted from manufacturers to retail giants such as Walmart, Home Depot and Best Buy. The findings also propose a new route to counteract the emergence and rise of dominant retailers. On the other hand, with the application of new technology in the retail industry such as 3D avatar, AR/VR, Internet of Things, consumers are more likely to participate in various forms of co-production activities, how to execute the co-production strategy has become more and more important for managers.

The conclusion of this study points out the way to achieve a win–win outcome under which both channel members including manufacturer and retailers and consumers can be better off, that is, the channel can reach Pareto improvement, so the social welfare is increased accordingly.

The authors propose an analytical framework to examine the effects of co-production and competition on market segmentation and profitability, and prove that co-production is a powerful marketing tool that can attract consumers and increase profitability, which manufacturers can incorporate into their products even in a competitive environment.
