In economics, inflation is a rise in the general level of prices of goods and services in an economy over a period of time. When the general price level rises, each unit of currency buys fewer goods and services. Consequently, inflation also reflects an erosion in the purchasing power of money – a loss of real value in the internal medium of exchange and unit of account in the economy. A chief measure of price inflation is the inflation rate, the annualized percentage change in a general price index (normally the Consumer Price Index) over time.

Inflation's effects on an economy are various and can be simultaneously positive and negative. Negative effects of inflation include a decrease in the real value of money and other monetary items over time, uncertainty over future inflation which may discourage investment and savings, and if inflation is rapid enough, shortages of goods as consumers begin hoarding out of concern that prices will increase in the future. Positive effects include ensuring central banks can adjust nominal interest rates (intended to mitigate recessions), and encouraging investment in non-monetary capital projects.

Alan Harvey Guth (born February 27, 1947) is an American theoretical physicist and cosmologist. Guth has researched elementary particle theory (and how particle theory is applicable to the early universe). Currently serving as Victor Weisskopf Professor of Physics at the Massachusetts Institute of Technology, he is the originator of the inflationary universe theory.

He graduated from MIT in 1968 in physics and stayed to receive a master's and a doctorate, also in physics.

As a junior particle physicist, Guth first developed the idea of cosmic inflation in 1979 at Cornell and gave his first seminar on the subject in January 1980. Moving on to Stanford University Guth formally proposed the idea of cosmic inflation in 1981, the idea that the nascent universe passed through a phase of exponential expansion that was driven by a positive vacuum energy density (negative vacuum pressure). The results of the WMAP mission in 2006 made the case for cosmic inflation very compelling.

Alan Guth was born on February 27, 1947 in New Brunswick, New Jersey. After his junior year at Massachusetts Institute of Technology, he enrolled in a five-year program where he could get his bachelor’s and master’s after two more years. Guth obtained a bachelor’s and master’s degree in 1969 and a doctorate in 1972. In 1971, he married Susan Tisch, his high school sweetheart. They have two children: Lawrence (born 1977) and Jennifer (born 1983).

Andrei Dmitriyevich Linde (Russian: Андрей Дмитриевич Линде; born March 2, 1948) is a Russian-American theoretical physicist and professor of Physics at Stanford University. Dr. Linde is best known for his work on the concept of the inflationary universe. He received his Bachelor of Science degree from Moscow State University. In 1975, Linde was awarded a Ph.D. from the Lebedev Physical Institute in Moscow. Among the various awards he's received for his work on inflation, in 2002 he was awarded the Dirac Medal, along with Alan Guth of MIT and Paul Steinhardt of Princeton University.

Linde is best known for proposing "eternal chaotic inflation" to explain a number of problems in cosmology. This variant of cosmic inflation proposes that the false vacuum is eternally inflating in exponential growth powered by repulsive constant random zero point dark energy of negative pressure. This false vacuum is like supersaturated steam in which liquid bubbles of more stable vacuum form with Higgs-Goldstone fields that describe the cohering of most of the pre-inflationary random dark energy into the smooth fabric of curved spacetime. Our universe is only a small causal part of a single bubble, and there are 10^10^10^7 bubbles. In fact, there are 10^10^10^7 of universes like ours on a single bubble which is more like an expanding infinite sheet than a finite spherical surface (suppressing 1 space dimension for ease of visualization).

Schiff is CEO and chief global strategist of Euro Pacific Capital Inc., a broker-dealer based in Westport, Connecticut and CEO of Euro Pacific Precious Metals, LLC, a gold and silver dealer based in New York City.

Schiff frequently appears as a guest on financial television and is often quoted in major financial publications. He is host of The Peter Schiff Show, a radio show broadcast on terrestrial and internet radio. He is a frequent guest on internet radio as well as the host of the former podcast Wall Street Unspun. In 2010 Schiff ran as a candidate in the Republican primary for the United States Senate seat from Connecticut.

Schiff is known for his bearish views on the dollar and dollar denominated assets, while bullish on investment in tangible assets as well as foreign stocks and currencies.

Peter Schiff was born and raised in New Haven, Connecticut. His father, Irwin Schiff, is a prominent figure in the U.S. tax protester movement, currently serving a 13-year sentence for tax evasion. Peter Schiff attended Beverly Hills High School in California, and graduated from the University of California, Berkeley in 1987 with a Bachelor's degree in finance and accounting.
