One bank offers a 2% variable rate loan all competitor offers a 3% fixed rate loan over the same period it is likely better to choose the fixed rate loan even though the interest rate is higher because the rate on the 1. is open to fluctuations 2. variable loan appears less active 3. variable loan can increase dramatically 4. variable loan will never increase

1. the rate on the variable loan is open to fluctuations.

A variable interest rate loan is a loan with an interest rate that varies as market interest rates change. As a result, payments can change too. On the other hand, fixed interest rate loans are those in which the interest rate charged in the loan remains fixed for the entire term of the loan, no matter what happens with market interest rates.

The disadvantage that a variable loan has when compared to a fixed rate loan is that the variable loan is open to fluctuations in market interest rates. This uncertainty means that it is possible for your payments to increase in the future.

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. : )
