Answer: Keynesian Economic Theory
Explanation: The policy adopted by the President was to cut back taxes and increase government spending on road, bridges and schools. This policy of the government is called the expansionary fiscal policy which is used to combat an economy suffering from recession. The Keynesian theory also supports the argument that when an economy is suffering from recession, economic output is influenced by aggregate demand. Thus, the government and use its fiscal policy tools to bring the economy out of recession. It also supports that the Fed can also use its monetary policy to bring the economy out of recession. But since here taxes and government spending are uses, we can say that Obama was a proponent of Keynesian Economic theory.
The shortest-route problem is a special case of the transshipment problem while transportation problems prevent shipments from entering and exiting some nodes, the transshipment problem does.
<h3>What are transshipment?</h3>
Transshipment is the loading and unloading of goods and stuff from one transport vehicle to another vehicle.
Transshipment happens because of no direct connection between the ports, due to this the goods are transported to different vehicles.

Answer:
Decision on the margins
Explanation:
Pool time seems to be having a greater effect at the moment, it makes sense for his to spend a bit more time in the pool and a bit less time on the bike.
However, this does not mean that it makes sense for her to spend all his time in the pool and no time on the bike. If he cut out all training on the bike, the value of a little bit of bike training might be higher than the value of the last hour of pool training. Dimitri does not treat biking versus swimming as an all-or-nothing decision. He makes small changes at the margin in the number of hours spent training for each activity.
Also they both realise that his time is fixed (20hrs) and anytime he wants to spend extra on one activit, is time he cannot spend on another (opportunity cost).
They are both trying to improve Dimitri's total time (exploiting opportunities to makes themselves better off).
An assumption that Dimitri realises that as he spends more time in the pool improving his swim time, his run and cycle times will suffer. As he swims more, his improvement is likely to slow down, while spending less time on cycling and running will cost him progressively more in terms of time.
Conclusion Dimitri is looking at the margins. His wife on the other hand, is not, she is ignoring the interaction, may be forgetting the decreasing improvements in swim and increasing deterioration in the other 2 legs.
Answer:
The correct answer is: a virtual corporation.
Explanation:
Virtual corporations are becoming more common with the massification of the internet and communications. They are generally companies that are dedicated to the commercialization of products and generate a massive movement in the network that allows them to be in the "voice to voice" of people. They do not have physical facilities, which saves them expenses such as leasing and public services, and the contracted staff is minimal. These companies are based on the strategy of fast and massive shipments through transport companies in order to satisfy the needs of their clients.
