I believe the answer is: scarcity and opportunity costs
A concert tend to happen on unpredicatble time, which make it considered to be scarce among fans. When we are forced to choose between going to concert or study, we would be forced to weigh the opportunity cost that arise when we sacrifice a certain option to pursue another, and choose the activity that give us the most benefit.

3. Set up budget system that both have to follow, Take in what they have, and ration it.
Bonus: One stops working, going back to home or working from home so the house does not get chaotic.
Potential rate of return on investments and the level of risk are directly correlated. In general, if the level of risk of investment increases, the amount of potential return increases as well. As investors move up on the 'pyramid of investment risk' the chances of losing increase along with the amount of potential return.
the internal validity is still manipulated by the researcher and the DV is measured.
The DV is a variable that is being measured/observed, whereas the IV is a variable that is altered to see how it impacts something else. The term "dependent" refers to the idea that the IV will have an impact on the DV.
<h3>What parallels exist between studies conducted in a lab and those conducted in the field?</h3>
Since experiments are the only way to reliably establish causality, laboratory and field experiments are comparable in that they are both helpful in determining cause and effect. Furthermore, because there is a high level of control over confounding variables, the two experiment designs have the potential to have high internal validity.
