Which explains the connection between the law of demand and excess demand ? ?

The decreases in price leads to greater quantity demanded and limited supply, which occurs during excess demand.

Supply and demand are two of the most important factors in the economy, as they identify the elements within a consumption relationship. When an item is traded, there are always two economic agents involved: one that buys and the other that sells, which are, respectively, the plaintiff and the offerer.

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )
