I can't really comment as ive only played a Theo techer in primary. For a non-demo i think the answer is obvious.
A point to add - if food is cheap, people might decide to stock earlier which means the demand for tech will be lower as people have lower land sizes. When food is expensive, its better to keep growing, which means they need more tech. So i would assume this will affect how tech prices are in the first place.
