Many governments end up with chronic budget deficits because a. some resources are not available from within, so they have to be bought from other nations. b. many government programs are popular with voters, but hardly any voter likes paying taxes. c. the nation simply cannot produce everything that it consumes, so it has to rely on other nations. d. businesses do not want to have "big government" around too much.

a. some resources are not available from within, so they have to be bought from other nations.

Explanation:

The budget deficit itself is an easily understood term. This third refers to the fact that a country spends more than it collects. That is, the tax paid by the population is not enough to cover the country's debts and expenses. This generates several bad results for the economy of the country, one of these results is that the country starts to stop producing some resources, and buy from other producing nations.

Many developed countries can manage to generate deficits year after year, one of the explanations for this is that they have some confidence in the market, but for those developing countries that do not have as much market confidence generate a deficit. Budgeting can be a real nightmare.

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. : )
