The Director of National Intelligence’s work involves coordinating the many intelligence's agencies in charge of security and espionage in our country.
<u>Explanation:</u>
Some of these have had historically conflicting objectives (the DEA efforts against drug trafficking conflicted with the CIA strategy to finance counter communism movements) and the operate with high degree of secrecy.
On the positive side, their work protects the life and safety of Americans from unknown threats.
On the negative side, the secrecy they operate makes them difficult to be held accountable and they operate in the margins of people’s rights. There’s a trade off between Security and Liberty, and sometimes the threats to security do not seem to justify the cutback on liberties.
<u>The optimality condition in the consumer's choice between two goods is the following</u>
<u>
</u>
The ratio of the marginal utilities is called the Marginal Rate of Substitution between goods x and y, and it arises from the preferences of the consumer towards the two goods. The MRS establishes the rate at which this consumer can give up a certain quantity of good x in exchange for another amount good y, while maintaining the same level of utility (it establishes the units of good x that would satisfy the consumer if he had to reject a certain number of units of y, given his personal preferences).
When MRS is equaled to the price ratio, it allows to calculate the bundle of goods x and y, that provides the maximum utility to this consumer given the market prices of x and y, which means that t<u>he solution provides the highest-utility bundle that he can afford. </u>
<u>If the rule does not hold, the choice might be either suboptimal or impossible.</u> When the result is suboptimal, the consumer acquires a bundle that he can afford but that is not the one yielding the maximum utility. If the result obtained is impossible, the consumer cannot afford the bundle, even tough it yields very high utility to him.
