Fundamental Methods of Mathematical Economics (COLLEGE IE (REPRINTS))

Product Information

very good math preparation book for econ major. It could be used to undergraduate text, or graduate review book, since the level is a bit lower. Lccn 83019609 Ocr ABBYY FineReader 11.0 (Extended OCR) Ocr_converted abbyy-to-hocr 1.1.11 Ocr_module_version 0.0.14 Old_pallet IA14991 Openlibrary_edition The Qualitative-Graphic Approach 495 The Phase Diagram 495 Types of Time Path 496 Exercise 15.6 498 Leontief Input-Output Models 112 Structure of an Input-Output Model 112 The Open Model 113 A Numerical Example 115 The Existence of Nonnegative Solutions 116 Economic Meaning of the Hawkins-Simon Condition 118 The Closed Model 119 Exercise 5.7 120 However, the author is very good at organizing material. Each part is started with an intuitive instruction and is closed with conclusion part which states the limitation with a certain method. So although this is a math book, the words really account, which really helps you to understand.

Rather, it is an approach to economic analysis, in which the economist makes use of mathematical symbols in the statement of the problem and also draws upon known mathematical theorems to aid in reasoning. As far as the specific subject matter of analysis goes, it can be micro- or macroeconomic theory, public finance, urban economics, or what not. Using the term mathematical economics in the broadest possible sense, one may very well say that every elementary textbook of economics today exemplifies mathematical economics insofar as geometrical methods are frequently utilized to derive theoretical results. More commonly, however, mathematical economics is reserved to describe cases employing mathematical techniques beyond simple geometry, such as matrix algebra, differential and integral calculus, differential equations, difference equations, etc. It is the purpose of this book to introduce the reader to the most fundamental aspects of these mathematical methods—those encountered daily in the current economic literature.
