Econometrics, the result of a certain outlook on the role of economics, consists of the applica- tion of mathematical statistics to economic data to lend empirical support to the models constructed by mathematical economics and to obtain numerical results. Econometrics may be defined as the social science in which the tools of economic theory, mathematics, and statistical inference are applied to the analysis of economic phenomena.
The art of the econometrician consists in finding the set of assumptions that are both suffi- ciently specific and sufficiently realistic to allow him to take the best possible advantage of the data available to him. The method of econometric research aims, essentially, at a conjunction of economic theory and actual measurements, using the theory and technique of statistical inference as a bridge pier.
Samuelson, T. Koopmans, and J. Darnell and J. As the preceding definitions suggest, econometrics is an amalgam of economic theory, mathematical economics, economic statistics, and mathematical statistics. Yet the subject deserves to be studied in its own right for the following reasons. Economic theory makes statements or hypotheses that are mostly qualitative in nature.
For example, microeconomic theory states that, other things remaining the same, a reduc- tion in the price of a commodity is expected to increase the quantity demanded of that com- modity. Thus, economic theory postulates a negative or inverse relationship between the price and quantity demanded of a commodity.
But the theory itself does not provide any numerical measure of the relationship between the two; that is, it does not tell by how much the quantity will go up or down as a result of a certain change in the price of the commod- ity. It is the job of the econometrician to provide such numerical estimates. Stated differ- ently, econometrics gives empirical content to most economic theory.
The main concern of mathematical economics is to express economic theory in mathe- matical form equations without regard to measurability or empirical verification of the theory. Econometrics, as noted previously, is mainly interested in the empirical verification of economic theory. As we shall see, the econometrician often uses the mathematical equations proposed by the mathematical economist but puts these equations in such a form that they lend themselves to empirical testing.
And this conversion of mathematical into econometric equations requires a great deal of ingenuity and practical skill. Economic statistics is mainly concerned with collecting, processing, and presenting economic data in the form of charts and tables.
These are the jobs of the economic statisti- cian. It is he or she who is primarily responsible for collecting data on gross national product GNP , employment, unemployment, prices, and so on.
The data thus collected constitute the raw data for econometric work. But the economic statistician does not go any further, not being concerned with using the collected data to test economic theories. Of course, one who does that becomes an econometrician.
Although mathematical statistics provides many tools used in the trade, the econometri- cian often needs special methods in view of the unique nature of most economic data, namely, that the data are not generated as the result of a controlled experiment.
The econo- metrician, like the meteorologist, generally depends on data that cannot be controlled directly. As Spanos correctly observes:. In econometrics the modeler is often faced with observational as opposed to experimental data.
This has two important implications for empirical modeling in econometrics. First, the modeler is required to master very different skills than those needed for analyzing experimen- tal data. How do econometricians proceed in their analysis of an economic problem? That is, what is their methodology? Although there are several schools of thought on econometric methodology, we present here the traditional or classical methodology, which still domi- nates empirical research in economics and other social and behavioral sciences.
See also Aris Spanos, op. To illustrate the preceding steps, let us consider the well-known Keynesian theory of consumption. The fundamental psychological law. In short, Keynes postulated that the marginal propensity to consume MPC , the rate of change of consumption for a unit say, a dollar change in income, is greater than zero but less than 1.
Specification of the Mathematical Model of Consumption Although Keynes postulated a positive relationship between consumption and income, he did not specify the precise form of the functional relationship between the two. For simplicity, a mathematical economist might suggest the following form of the Keynesian consumption function:. Geometrically, Equation I. This equation, which states that consumption is linearly related to income, is an example of a mathematical model of the relationship between consumption and income that is called the consumption function in economics.
A model is simply a set of mathe- matical equations. If the model has only one equation, as in the preceding example, it is called a single-equation model, whereas if it has more than one equation, it is known as a multiple-equation model the latter will be considered later in the book. In Eq. Thus, in the Keynesian consumption function, Eq.

This chapter discusses and illustrates some comparatively simple methods of estimating nonlinear-in-parameter regression models.
Chapter 15, on qualitative response regression models, which replaces old Chapter 16, on dummy dependent variable regression models, provides a fairly extensive discussion of regression models that involve a dependent variable that is qualitative in nature.
The chapter also discusses the Poisson regression model, which is used for modeling count data, such as the number of patents received by a firm in a year; the number of telephone calls received in a span of, say, 5 minutes; etc.
This chapter has a brief discussion of multinomial logit and probit models and duration models. Chapter 16, on panel data regression models, is new. A panel data combines features of both time series and cross-section data. Because of increasing availability of panel data in the social sciences, panel data regression models are being increasingly used by researchers in many fields.
This chapter provides a nontechnical discussion of the fixed effects and random effects models that are commonly used in estimating regression models based on panel data. Chapter 17, on dynamic econometric models, has now a rather extended discussion of the Granger causality test, which is routinely used and misused in applied research.
The Granger causality test is sensitive to the number of lagged terms used in the model. It also assumes that the underlying time series is stationary. Except for new problems and minor extensions of the existing estimation techniques, Chapters 18, 19, and 20 on simultaneous equation models are basically unchanged. This reflects the fact that interest in such models has dwindled over the years for a variety of reasons, including their poor forecasting performance after the OPEC oil shocks of the s.
Chapter 21 is a substantial revision of old Chapter Several concepts of time series econometrics are developed and illustrated in this chapter. The main thrust of the chapter is on the nature and importance of stationary time series.
The chapter discusses several methods of finding out if a given time series is stationary. Stationarity of a time series is crucial for the application of various econometric techniques discussed in this book. Chapter 22 is also a substantial revision of old Chapter It also discusses the topic of measuring volatility in financial time series by the techniques of autoregressive conditional heteroscedasticity ARCH and generalized autoregressive conditional heteroscedasticity GARCH.
Appendix A, on statistical concepts, has been slightly expanded. Appendix C discusses the linear regression model using matrix algebra. This is for the benefit of the more advanced students. As in the previous editions, all the econometric techniques discussed in this book are illustrated by examples, several of which are based on concrete data from various disciplines. The end-of-chapter questions and problems have several new examples and data sets.
For the advanced reader, there are several technical appendices to the various chapters that give proofs of the various theorems and or formulas developed in the text. I hope this gives the instructor substantial flexibility in choosing topics that are appropriate to the intended audience. Here are suggestions about how this book may be used. One-semester course for the nonspecialist: Appendix A, Chapters 1 through 9, an overview of Chapters 10, 11, 12 omitting all the proofs.
One-semester course for economics majors: Appendix A, Chapters 1 through Two-semester course for economics majors: Appendices A, B, C, Chapters 1 to Chapters 14 and 16 may be covered on an optional basis.
Some of the technical appendices may be omitted.
