Plant-based meat alternatives (PBMA), you might like them or not, significantly help reach greenhouse gas emission targets. But how can the attractiveness of PBMA products be increased for consumers? This question is essential for retailers, manufacturers, and governmental decision-makers.

Examining the UK market for PBMA burger patties, Paul Naughton (Edinburgh Napier University), Joshua Schramm, and Marcel Lichters  have uncovered promising insights. Their study, recently published in Food Quality and Preference, delves into the role of effective front-of-pack labelling strategies, offering a beacon of hope for the future of sustainable food options.

Our findings:

• Consumers can be grouped into 3 distinct segments in terms of preference for front-of-pack labels: (1) nutritious information, (2) ecological information, (3) taste information
• Price plays the most significant role for consumers when deciding between PBMA or meat products; however ...
• Highlighting taste via an accredited taste label can enhance PBMA’s appeal and convince consumers to switch from meat alternatives to PBMA

These findings underscore the practical implications of the right labeling strategy in promoting sustainable food consumption. The article also equips you with valuable information on segment profiles in the UK and the potential impact of different labels on willingness to pay.

We would happily evaluate similar questions for retailers or manufacturers operating in other countries. You can find the article for free here.

Check out our new R package published in The Journal of Open Source Software.

 In recent years, during discussions with specific small and medium-sized market research providers and marketing departments, we observed that studies on preference elicitation through Conjoint analysis or (anchored) Maximum Difference Scaling (MaxDiff) rarely include measures to assess the predictive (out-of-calibration) validity in holdout tasks to ensure data quality in managerial decision-making.

The reasons for this neglect may be manifold:

• Functions for implementing and validating holdout tasks are often not fully integrated into commercial software solutions that handle Conjoint and MaxDiff studies.
• A lack of time in the fast-paced market research industry
• Insufficient training for participating market research managers
• Ultimately, professional online panel providers have no incentive to address previously unmentioned data quality issues.

 Our new R package validateHOT comes into play (see GitHub for tutorials).

Beginning with a few functions we provided to our students during Conjoint seminars at the Otto von Guericke University Magdeburg, we have now consolidated several functions into a package that offers tools for validating holdout tasks and preparing basic market simulations, among other features. The package also helps with Total-Unduplicated-Reach-and-Frequency (T.U.R.F) analysis. It integrates seamlessly with (Adaptive) Choice-based Conjoint or MaxDiff as conducted by popular proprietary packages commonly used by companies.

Have you ever wondered whether incentive alignment in conjoint analysis is worth the additional costs? Based on our latest meta-analysis, we would say … yes, it is!

Conjoint analyses are often conducted in hypothetical settings where participants are not sufficiently motivated to invest the same mental effort as in an actual purchase situation. This can lead to significant losses and missed opportunities for companies relying on the resultant biased preferences. One effective workaround is to apply incentive alignment.

Our recent meta-analysis, published in Marketing Letters with 12,980 participants, shows that incentive-aligning conjoint analysis increases the prediction accuracy of consumer choices by 12%.

In the meta-analysis, we also find that incentive alignment is more effective for durable and service goods (compared to FMCGs) and when applied with adaptive choice-based conjoint analysis. The latter mirrors our recent findings from a JAMS article.

Our meta-analysis concludes with practical guidelines for market researchers. These include a detailed discussion on the cost implications of incentive-aligning a conjoint analysis, providing valuable insights and equipping researchers with the necessary knowledge for those considering this approach.

We warmly invite you to explore our open-access article, which comprehensively overviews our research findings. This is your chance to enjoy the article for free and delve deeper into the world of incentive alignment in conjoint analysis.
