The God theory is not just a bad theory.

And that is why so many economists and market participants were shocked by Yellen s apparent complacency. With US unemployment now at 5.1 , standard monetary theory dictates that interest rates must be raised urgently.

It was begun with the invention of relativity theory and quantum theory.

Second, exchange rates need to reflect economic fundamentals. But while theory suggests that flexible exchange rates should blunt foreign monetary or financial shocks, in practice, such a currency regime rarely works on its own.

It is to Phelps that we owe the theory of the natural unemployment rate a cornerstone of modern macroeconomic theory and economic policy that Milton Friedman rediscovered a year later, albeit heuristically. Phelps was also responsible for the island parable, which helped explain why monetary policy can have temporary real effects as a result of imperfect information.

The currency was in theory governed by a rules based Currency Board, which the British invented for their smaller colonies. It tied the local currency to the British Pound, giving local authorities no discretion in monetary policy.

The problems with having a theory is that your theory may be loaded with cognitive biases.

So, while monetary policy can in theory be automated, as computer programmers say, garbage in, garbage out. Stock and housing prices may be volatile, but the data are much cleaner and timelier than anything available for output and inflation.

So without a theory of planetary rings and with only grainy data, you can't have a good theory.

And he was reading Einstein's recently published general theory of relativity, and he was thrilled by this theory.

It was called the upsuck theory.

It's the same theory of gravity.

They follow from the fundamental theory.

Now, what is game theory about?

They opposed Darwin's theory of evolution.

It's difficult to understand his theory.

Your theory has no scientific basis.

He put forward a new theory.

I'm a biologist, and the central theorem of our subject the theory of design, Darwin's theory of evolution by natural selection.

Stephen Wolfram Computing a theory of everything

Now, does string theory offer an answer?

Denis Dutton A Darwinian theory of beauty

I think your basic theory is wrong.
