text_A: Sterling Archer is a famous name.
text_B: Mathematical economics is the application of mathematical methods to represent theories and analyze problems in economics .. economics. economics. By convention , the applied methods refer to those beyond simple geometry , such as differential and integral calculus , difference and differential equations , matrix algebra , mathematical programming , and other computational methods .. applied methods. Applied mathematics#Economics. calculus. calculus. difference. difference equations. differential equations. differential equations. matrix algebra. Matrix ( mathematics ). mathematical programming. mathematical programming. computational methods. Computational economics. An advantage claimed for the approach is its allowing formulation of theoretical relationships with rigor , generality , and simplicity .. Mathematics allows economists to form meaningful , testable propositions about wide-ranging and complex subjects which could less easily be expressed informally .. Further , the language of mathematics allows economists to make specific , positive claims about controversial or contentious subjects that would be impossible without mathematics .. positive. Positive science. Much of economic theory is currently presented in terms of mathematical economic models , a set of stylized and simplified mathematical relationships asserted to clarify assumptions and implications .. economic models. Model ( economics ). Broad applications include  :. optimization problems as to goal equilibrium , whether of a household , business firm , or policy maker. optimization. mathematical optimization. equilibrium. Economic equilibrium. static -LRB- or equilibrium -RRB- analysis in which the economic unit -LRB- such as a household -RRB- or economic system -LRB- such as a market or the economy -RRB- is modeled as not changing. equilibrium. Economic equilibrium. economy. economy. comparative statics as to a change from one equilibrium to another induced by a change in one or more factors. equilibrium.

Comparative dynamics. economic growth. economic growth. Formal economic modeling began in the 19th century with the use of differential calculus to represent and explain economic behavior , such as utility maximization , an early economic application of mathematical optimization .. calculus. calculus. optimization. mathematical optimization. differential calculus. differential calculus. utility. utility. mathematical optimization. mathematical optimization. Economics became more mathematical as a discipline throughout the first half of the 20th century , but introduction of new and generalized techniques in the period around the Second World War , as in game theory , would greatly broaden the use of mathematical formulations in economics .. economics. economics.

John Maynard Keynes , Robert Heilbroner , Friedrich Hayek and others have criticized the broad use of mathematical models for human behavior , arguing that some human choices are irreducible to mathematics ..
