Optimal stopping problems can be found in areas of statistics, economics, and mathematical finance (related to the pricing of American options). A key example of an optimal stopping problem is the secretary problem .
A Lorenz curve always starts at (0,0) and ends at (1,1). The Lorenz curve is not defined if the mean of the probability distribution is zero or infinite. The Lorenz curve for a probability distribution is a continuous function. However, Lorenz curves representing discontinuous functions can be constructed as the limit of Lorenz curves of ...
The goal is to find models in which existence of money can alter the equilibrium solutions, perhaps because the initial position of agents depends on monetary prices. Some critics of general equilibrium modeling contend that much research in these models constitutes exercises in pure mathematics with no connection to actual economies.
Equity premium puzzle: The equity premium puzzle is thought to be one of the most important outstanding questions in neoclassical economics. [6] It is founded on the basis that over the last one hundred years or so the average real return to stocks in the US has been substantially higher than that of bonds.
Economics classes make extensive use of supply and demand graphs like this one to teach about markets. In this graph, S and D refer to supply and demand and P and Q refer to the price and quantity. The following outline is provided as an overview of and topical guide to economics:
The solution to these problems is important because of the "fundamental fact of economic institution life" that ... [ 2 ] "The economic problem, "the struggle for subsistence", always has been hitherto primary, most pressing problem of the human race- not only of the human race, but of the whole of the biological kingdom from the beginnings of ...
The solution of the resulting system of equations (both linear and non-linear) is the general equilibrium. [25] At the time, no general solution could be expressed for a system of arbitrarily many equations, but Walras's attempts produced two famous results in economics. The first is Walras' law and the second is the principle of tâtonnement.
Supply chain as connected supply and demand curves. In microeconomics, supply and demand is an economic model of price determination in a market.It postulates that, holding all else equal, the unit price for a particular good or other traded item in a perfectly competitive market, will vary until it settles at the market-clearing price, where the quantity demanded equals the quantity supplied ...
