The book starts with a summary of basic skills and takes its readers as far as constrained optimisation helping them to become confident and competent in the use of mathematical tools and techniques that can be applied to a range of problems in economics and finance. Designed as both a course text and a handbook, the book assumes little prior mathematical knowledge beyond elementary algebra and is therefore suitable for students returning to mathematics after a long break. The fundamental ideas are described in the simplest mathematical terms, highlighting threads of common mathematical theory in the various topics.

These were mathematics courses in an economics setting, given by mathematicians based in the Department of Mathematics for students in the Faculty of Social Sciences or School of Man- agement. The majority of students to whom these courses were given were study- ing for degrees in economics or business administration and had not acquired any mathematical knowledge beyond pre-calculus mathematics, i.

This course led on to the more advanced second-semester course, which was also suitable for students who had already covered basic calculus. The second course contained at most one of the three Chapters 10, 12, and In any particular year, their inclusion or exclusion would depend on the requirements of the economics or business studies degree syllabuses. The authors have not at- tempted to write an undergraduate text in economics but instead have written a text in mathematics to complement those in economics.

The simplicity of a mathematical theory is sometimes lost or obfuscated by a dense covering of applications at too early a stage. Some knowledge of theory is necessary if correct use is to be made of the techniques; therefore, the authors have endeavoured to introduce some basic theory in the expectation and hope that this will improve understanding and incite a desire for a more thorough knowledge.

They will also be in a better position to understand and be in control of calculations done by hand or calculator and also to be able to visualise problems graphically or geometrically.

It is still true that the best way to understand a technique thoroughly is through practice. Mathematical techniques are no exception, and for this reason the book illustrates theory through many examples and exercises.

We are grateful to Noreen Davies and Joe Hill for invaluable help in prepar- ing the manuscript of this book for publication. Above all, we are grateful to our wives, Nesta and Gill, and to our chil- dren, Nicholas and Christiana, and Rebecca, Christopher, and Emily, for their patience, support, and understanding: this book is dedicated to them.

In this introductory chapter, the reader is reacquainted with some of the basic principles of arithmetic and algebra that formed part of their previous mathematical education. Mathematics is a subject that can only be learnt by doing examples, and therefore students are urged to work through the examples in this chapter to ensure that these key skills are understood and mastered. The counting numbers are collectively known as the natural numbers.

The natural numbers can be represented by equally spaced points on a line as shown in Fig. The direction in which the arrow is pointing in Fig.

It is sometimes useful and necessary to talk in terms of numbers less than zero. For example, a person with an overdraft on their bank account essentially has a negative balance or debt, which needs to be cancelled before the account is in credit again. In the physical world, negative numbers are used to report temperatures below 00 Centigrade, which is the temperature at which water freezes.

If the line in Fig. The nat- ural numbers, their negatives, and the number zero are collectively known as the integers. All these numbers can be represented by equally spaced points on a number line as shown in Fig. If we move along the line to the right, the numbers become progressively larger, while if we move along the line to the left, the numbers become smaller. Essential Skills 3 X -4 -3 -2 -1 0 1 2 3 4 5 Figure 1. We say that ab is the product of a and b. Thus, we can write 1.

Therefore, the order in which the mathematical operations are performed is important and the convention is as follows: brackets, exponents, division, multiplication, addition, and subtraction. So that the evaluation of expressions within brackets takes precedence over addition and the evaluation of any number or expressions raised to a power an exponential takes prece- dence over division, for example. However, the main point to remember is that if you want a calculation to be done in a particular order, you should use brackets to avoid any ambiguity.

Essential Skills 5 Example 1. The integers a and b are known as the numerator and denominator of the fraction, respectively.

Note that a can be greater than b. The formal name for a fraction is a rational number since they are formed from the ratio of two numbers.

This is achieved by identifying any common factors in the numerator and denominator and then cancelling those factors by dividing both numerator and denominator by them. To compare the relative sizes of two fractions and also to add or subtract two fractions, we express them in terms of a common denominator. The com- mon denominator is a number that each of the denominators of the respective fractions divides, i. The simplest way to compare the relative sizes is to multiply the numerator and denominator of each fraction by the denominator of the other, i.

We follow a similar procedure when we want to add two fractions. The idea is to express each of these fractions as equivalent fractions having a common denominator. Essential Skills 7 Note that a smaller common denominator, namely 48, could have been used in this example since the two denominators, viz.

Using the rule 1. Its decimal representation is 0. This is an example of a recurring decimal. Essential Skills 9 form the real numbers. Every point on the number line in Fig. For example, 2 1 0.

Suppose that we wish to write the number To do this, we truncate the part of the number following the second digit after the decimal point: If we wish to write the same number correct to three decimal places, the truncated number is Therefore, the number The mass of an electron is 0. This is a shorthand means of expressing very large or very small numbers. The standard form of a number expresses it in terms of a number lying between 1 and 10 multiplied by 10 raised to some power or exponent.

For example, the standard form of 0. The power gives the number of decimal places the decimal point needs to be moved to the right in the case of a positive power or the number of decimal places the decimal point needs to be moved to the left in the case of a negative power.

For example, 5. Returning to the above examples, the Earth is about 1. What is the price of the refrigerator without sales tax? Here x is known as the base and n is the power or index or exponent. There are rules for multiplying and dividing two algebraic expressions or numerical values involving the same base raised to a power. Suppose we wish to raise an expression with a power to a power, for example x2 4.

These rules for simplifying expressions involving powers may be used to evaluate arithmetic expressions without using a calculator. For example, consider xy 3. Essential Skills 15 Solution. Using the quotient rule 1. Expressions consisting simply of a coefficient multiplying one or more variables raised to the power of a positive integer are called monomials.

Monomials can be added or subtracted to form polynomials. Each of the monomials comprising a poly- nomial is called a term.

The coefficient of x2 is 3, the coefficient of x is 2, and the constant term is 1. To add or subtract two polynomials, we collect like terms and add or sub- tract their coefficients. Example 1. This process, which is also known as expanding the brackets or multiplying out the brackets, culminates in an equivalent ex- pression without brackets. Essential Skills 17 where a, b, and c are any three numbers. It is important to take care multiplying out brackets when there is a negative sign outside the brackets.

Elements of Numerical Mathematical Economics with Excel - Ebook

Elements of Numerical Mathematical Economics with Excel: Static and Dynamic Optimization shows readers how to apply static and dynamic optimization theory in an easy and practical manner, without requiring the mastery of specific programming languages that are often difficult and expensive to learn. Featuring user-friendly numerical discrete calculations developed within the Excel worksheets, the book includes key examples and economic applications solved step-by-step and then replicated in Excel. After introducing the fundamental tools of mathematical economics, the book explores the classical static optimization theory of linear and nonlinear programming, applying the core concepts of microeconomics and some portfolio theory.

Mathematical economics is the application of mathematical methods to represent theories and analyze problems in economics. By convention, these applied methods are beyond simple geometry, such as differential and integral calculus , difference and differential equations , matrix algebra , mathematical programming , and other computational methods. 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.

Оказавшись в условиях подлинного разведывательного затемнения, АНБ выпустило секретную директиву, одобренную президентом Соединенных Штатов. Заручившись поддержкой федеральных фондов и получив карт-бланш на все необходимые меры для решения проблемы, АНБ приступило к созданию невозможного - первой универсальной машины для вскрытия шифров. Вопреки широко распространенному мнению о том, что такой компьютер создать невозможно, АНБ осталось верным своему девизу: возможно все; на невозможное просто требуется больше времени. Через пять лет, истратив полмиллиона рабочих часов и почти два миллиарда долларов, АН Б вновь доказало жизненность своего девиза. Последний из трех миллионов процессоров размером с почтовую марку занял свое место, все программное обеспечение было установлено, и керамическая оболочка наглухо заделана. ТРАНСТЕКСТ появился на свет.

 Я тебя предупредил! - кипятился панк.  - Это мой столик. Я прихожу сюда каждый вечер. Подними, говорю. Беккер терял терпение. А ведь он мог быть сейчас в Смоки-Маунтинс, со Сьюзан.

 Нет. Мы к нему не прикасались. Мой друг испугался. Он хоть и крупный, но слабак.  - Она кокетливо улыбнулась Беккеру.  - Не волнуйтесь, он ни слова не понимает по-испански.

 - Он даже не служит у. Стратмор был поражен до глубины души. Никто никогда не позволял себе говорить с заместителем директора АНБ в таком тоне. - Сьюзан, - проговорил он, стараясь сдержать раздражение, - в этом как раз все. Мне было нужно… Но тигрица уже изготовилась к прыжку.

От нее исходил легкий аромат присыпки Джонсонс беби.
