Hoarding is the act of engaging in excessive acquisition of items that are not needed or for which no space is available.
Civil unrest or the threat of natural disasters may lead people to hoard foodstuffs, water, gasoline, and other essentials that they believe will soon be in short supply. Survivalists, also known as preppers, often stockpile large supplies of these items in anticipation of a large-scale disaster event.
Compulsive behavior (or compulsion) is defined as performing an action persistently and repetitively. Compulsive behaviors could be an attempt to make obsessions go away. Compulsive behaviors are a need to reduce apprehension caused by internal feelings a person wants to abstain from or control. A major cause of compulsive behavior is obsessive–compulsive disorder (OCD). "Compulsive behavior is when someone keeps doing the same action because they feel like they have to, even though they know these actions do not align with their goals." There are many different types of compulsive behaviors including shopping, hoarding, eating, gambling, trichotillomania and picking skin, itching, checking, counting, washing, sex, and more. Also, there are cultural examples of compulsive behavior.
In macroeconomic theory, liquidity preference is the demand for money, considered as liquidity. The concept was first developed by John Maynard Keynes in his book The General Theory of Employment, Interest and Money (1936) to explain the determination of the interest rate by the supply and demand for money.The liquidity preference theory by Keynes was a refinement of Silvio Gesell's theory that interest is caused by the store of value function of money.
The demand for money as an asset was theorized to depend on the interest foregone by not holding bonds (here, the term "bonds" can be understood to also represent stocks and other less liquid assets in general, as well as government bonds). Interest rates, he argues, cannot be a reward for saving as such because, if a person hoards his savings in cash, keeping it under his mattress say, he will receive no interest, although he has nevertheless refrained from consuming all his current income. Instead of a reward for saving, interest, in the Keynesian analysis, is a reward for parting with liquidity. According to Keynes, money is the most liquid asset. Liquidity is a potentially valuable attribute of an asset, in circumstances requiring cash money to meet obligations or contingencies. The more quickly an asset can be converted into cash money at or near the present value of its expected long-term cash flow, the more liquid it is said to be.
