7. Limitations and future research
Our research presents several other interesting questions that have considerable practical implications. For example, personality variables (i.e., creativity, liking to work with one's hands) may moderate the value created through different stages of production and are domains ripe for exploration. Consumers who enjoy working with their hands and expressing themselves through physical labor may identify with self-made products even if they only participate in the realization stage, since manual labor is part of their self-identity. Our studies involved university students who may have higher needs for cognition than many non-students and may value design more than assembly or customized construction opportunities. Hence, design participation may have been relatively more important for our population and may add more value than craftsmanship or manual effort.
