Finance
Finance is a field that deals with the study of investments. It includes the dynamics of assets and liabilities over time under conditions of different degrees of uncertainties and risks. Finance can also be defined as the science of money management. Market participants aim to price assets based on their risk level, fundamental value, and their expected rate of return. Finance can be broken into three sub-categories: public finance, corporate finance and personal finance.
Real Estate
Real estate is "property consisting of land and the buildings on it, along with its natural resources such as crops, minerals or water; immovable property of this nature; an interest vested in this (also) an item of real property, (more generally) buildings or housing in general. Also: the business of real estate; the profession of buying, selling, or renting land, buildings, or housing." It is a legal term used in jurisdictions whose legal system is derived from English common law, such as India, the United Kingdom, United States, Canada, Pakistan, Australia, and New Zealand.
Finance
There’s no longer any reason to believe that the wizards of Wall Street actually contribute anything positive to society, let alone enough to justify those humongous paychecks. ... It’s hard to think of any major recent financial innovations that actually aided society, as opposed to being new, improved ways to blow bubbles, evade regulations and implement de facto Ponzi schemes.
Paul Krugman, "Money For Nothing," The New York Times, April 26, 2009
Economics
The field of economics is not exempt from the consequences of chaos and complexity. Marketplaces are indeterminate; value is subjective; and outcomes are subject to interpretation. Economic forecasting is just as nebulous, being based on the probability of statistical information that may or may not be accurate.
