Calculus can be thought of as the mathematics of change. Because everything in the world is changing, calculus helps us track those changes. Algebra, by contrast, can be thought of as dealing with a large set of numbers that are inherently constant. Solving an algebra problem, like \( y = 2x + 5 \), merely produces a pairing of two predetermined numbers, although an infinite set of pairs. Algebra is even useful in rate problems, such as calculating how the money in your savings account increa...

_It might make sense just to get some in case it catches on. If enough people think the same way, that becomes a self-fulfilling prophecy. _ _- Satoshi Nakamoto, January 16, 2009 _ Bitcoin has become its own monetary pyramid due to its properties as a first-layer money. The pyramid is reminiscent of gold-anchored pyramids of the past, but BTC doesn't derive its first-layer status solely from comparisons and metaphors; Satoshi designed a digital asset that specifically mimicked precious metals...

* A trolley car is hurtling out of control down a track where there are five workers ahead. You are standing by a switch that can divert the car onto a side track, where only one worker is currently, but that worker is your best friend. If you do nothing, the five workers will be killed, and if you throw the switch, your friend will be killed (but the five will be spared). There is no time to warn the workers or take any other action. Should you throw the switch or not? Does your answer chan...

Governments report proprietary fund assets, liabilities, and net position in a _Statement of Net Position_. Proprietary fund statements draw a distinction between major and non-major proprietary funds. Bothell is unique in that it did not have any non-major proprietary funds. There are only three funds – Water, Sewer, and Storm and Surface Water. Total assets in Water ($25.9 million), Sewer ($23.5 million), and Storm and Surface Water ($42.2 million) add up to the total assets reported under ...

The _Statement of Revenues, Expenditures, and Changes in Fund Balance_ is an income statement prepared on a modified accrual basis in the governmental fund statements. It lists the revenues, expenditures, and the change in fund balances. In this case, changes in fund balance are akin to changes in net assets or changes in net position. Bothell's Statement of Revenues, Expenditures, and Changes in Fund Balances shows that its two largest overall revenue sources are taxes ($40.5 million in the ...

The payback period is considered a method of analysis with serious limitations and qualifications because it does not account for the time value of money, risk, financing, or other important considerations, such as opportunity cost. While the time value of money can be rectified by applying a weighted average cost of capital discount, it is generally agreed that this tool for investment decisions should not be used in isolation. Alternative measures of "return" economists prefer are net prese...

In this section, we discuss the idea of calculating a Beta coefficient to help investors measure the risk-reward trade-off for a blended pool of investments. In this case, it is important to remember that a portfolio may represent the seller's side of the market, and the buyer can be an institutional investor or a mutual fund. A portfolio's Beta is the volatility correlated to an underlying index. If we consider the S&P 500 as the index, a portfolio that fluctuates identically to the market h...

The Global Settlement was an enforcement agreement to address issues of conflict of interest within the SEC and other big investment companies. The Global Settlement was an enforcement agreement reached on April 28, 2003 between the Securities and Exchange Commission (SEC), National Association of Securities Dealers (NASD), New York Stock Exchange (NYSE), and ten of the United States's largest investment firms. The agreement was meant to address issues of conflict of interest within their bus...

Read this section on how to identify the different actors that participate in a stock market, differentiate the New York Stock Exchange from other stock exchanges, distinguish the NASDAQ from other stock exchanges, and explain how a market index works and its purpose. The individual actors in the financial markets can be divided into three main categories: investors, intermediaries, and issuers.
