The Ramsey problem, or Ramsey pricing, or Ramsey–Boiteux pricing, is a second-best policy problem concerning what prices a public monopoly should charge for the various products it sells in order to maximize social welfare (the sum of producer and consumer surplus) while earning enough revenue to cover its fixed costs.
The potential of modern financial economics theory to complement existing actuarial science was recognized by actuaries in the mid-twentieth century. [11] In the late 1980s and early 1990s, there was a distinct effort for actuaries to combine financial theory and stochastic methods into their established models. [12]
Price theory was a significant aspect of his legacy as a teacher, and he taught the subject from 1946 to 1964 and again from 1972 to 1976. Notable economists who took Friedman's price theory course include James M. Buchanan , Gary Becker , and Robert Lucas Jr. , all of whom later became Nobel laureates.
Another modern development is the convergence of modern finance theory with actuarial science. [47] In the early 20th century, some economists and actuaries were developing techniques that can be found in modern financial theory, but for various historical reasons, these developments did not achieve much recognition.
In financial economics, asset pricing refers to a formal treatment and development of two interrelated pricing principles, [1] [2] outlined below, together with the resultant models. There have been many models developed for different situations, but correspondingly, these stem from either general equilibrium asset pricing or rational asset ...
In a discrete (i.e. finite state) market, the following hold: [2] The First Fundamental Theorem of Asset Pricing: A discrete market on a discrete probability space (,,) is arbitrage-free if, and only if, there exists at least one risk neutral probability measure that is equivalent to the original probability measure, P.
Actuarial science – discipline that applies mathematical and statistical methods to assess risk in the insurance and finance industries. What type of thing is actuarial science? [ edit ]
Risk premium is the product of the market price of risk and the quantity of risk, and the risk is the standard deviation of the portfolio. The CML equation is : R P = I RF + (R M – I RF)σ P /σ M. where, R P = expected return of portfolio I RF = risk-free rate of interest R M = return on the market portfolio σ M = standard deviation of the ...
