Econometric methods and practice have advanced greatly as a result, but the modern menu of econometric methods can seem confusing, even to an experienced number-cruncher.
Luckily, not everything on the menu is equally valuable or important. Some of the more exotic items are needlessly complex and may even be harmful. On the plus side, the core methods of applied econometrics remain largely unchanged, while the interpretation of basic tools has become more nuanced and sophisticated.
Mostly Harmless Econometrics. Regression models designed to control for variables that may mask the causal e¤ects of interest; 2. Instrumental variables methods for the analysis of real and natural experiments; 3. Di¤erences-in-di¤erences-type strategies that use repeated observations to control for unobserved omitted factors. The productive use of these basic techniques requires a solid conceptual foundation and a good understanding of the machinery of statistical inference.
Both aspects of applied econometrics are covered here. This book was written with these students in mind. At the same time, we hope the book will …nd an audience mostly harmless econometrics pdf free download other groups of researchers who have an urgent need for practical answers regarding choice of technique and the interpretation of research …ndings.
The concerns of applied econometrics are not fundamentally di¤erent from those in other social sciences or epidemiology. Anyone interested in using data to shape public policy or to promote public health must digest and use statistical results, mostly harmless econometrics pdf free download. Anyone interested in drawing useful inferences from data on people can be said to be an applied econometrician. Many textbooks provide a guide to research methods and there mostly harmless econometrics pdf free download some overlap between this book and others in wide use.
But our Companion di¤ers from econometrics texts in a number of important ways. This view shapes our approach to all research questions. Of course, mostly harmless econometrics pdf free download quasi-experimental research designs are more convincing than others, but the econometric methods used in these studies are almost always fairly simple. Consequently, our book is shorter and more focused than textbook treatments of econometric methods.
We emphasize the conceptual issues and simple statistical techniques that turn up in the applied research we read and do, and illustrate these ideas and techniques with many empirical examples. A second distinction we claim is a certain lack of seriousness.
Most econometrics texts appear to take econometric models very seriously. Typically these books pay a lot of attention to the putative failures of classical modelling assumptions such as linearity and homoskedasticity. Warnings are sometimes issued. We take a more forgiving and less literal-minded approach. A principle that guides our discussion is that the estimators in common use almost always have a simple interpretation that is not heavily model-dependent.
If the estimates you get are not the estimates you want, the fault lies mostly harmless econometrics pdf free download the econometrician and not the econometrics! A leading example is linear regression, which provides useful information about the conditional mean function regardless of the shape of this function. Likewise, instrumental variables methods estimate an average causal e¤ect for a well-de…ned population even if the instrument does not a¤ect everyone.
The conceptual robustness of basic econometric tools is grasped intuitively by many applied researchers, but the theory behind this robustness does not feature in most texts.
Our Companion also di¤ers from most econometrics texts in that, on the inference side, we are not much concerned with asymptotic e¢ ciency.
Rather, our discussion of inference is devoted mostly to the …nite-sample bugaboos that should bother practitioners. The main prerequisites for the material here are basic training in probability and statistics. We espe- cially hope that readers are comfortable with the elementary tools of statistical inference, such as t-statistics and standard errors.
Familiarity with fundamental probability concepts like mathematical expectation is also helpful, but extraordinary mathematical sophistication is not required. Although important proofs are presented, the technical arguments are not very long or complicated.
Unlike many upper-level econometrics texts, we go easy on the linear algebra. For this reason and others, our Companion should be an easier read than competing books. Grateful thanks to Princeton University Press for agreeing to distribute our Companion on these terms. Acknowledgments We had the bene…t of comments from many friends and colleagues as this project progressed. Special thanks are due to Alberto Abadie, David Autor, Amitabh Chandra, Monica Chen, John DiNardo, Joe Doyle, Jerry Hausman, Andrea Ichino, mostly harmless econometrics pdf free download, Guido Imbens, Rafael Lalive, Alan Manning, Karen Norberg, Barbara Petrongolo, James Robinson, mostly harmless econometrics pdf free download, Tavneet Suri, and Je¤ Wooldridge, who reacted to the draft at various stages.
They are not to blame for our presumptuousness or remaining mistakes. Thanks also go to our students at LSE and MIT. We would especially like to acknowledge the skilled and tireless research assistance of Brigham Frandsen, Cynthia Kinnan, and Chris Smith. The …rst describes the type of research agenda for which the material in subsequent chapters is most likely to be useful.
The second discusses the sense in which ex- periments, mostly harmless econometrics pdf free download, i. After this introduction, the three chapters of Part Mostly harmless econometrics pdf free download present core mate- rial on regression, mostly harmless econometrics pdf free download, instrumental variables, and di¤erences-in-di¤erences.
These chapters emphasize both the universal properties of the relevant estimators e. We then turn to important exten- sions in Part III. Chapter 6 covers regression discontinuity designs, which can be seen as either a variation on regression-control strategies or a type of instrumental variables strategy. In Chapter 7, we discuss the use of quantile regression for estimating e¤ects on distributions.
The last chapter covers important infer- ence problems that are missed by the textbook asymptotic approach. Some chapters include more technical or specialized sections that can be skimmed or skipped without missing out on the main ideas - these are indicated with a star.
Notation, an acronym glossary, and an index to empirical examples are gathered at the back of the book. But a coherent, interesting, and doable research agenda is the solid foundation on which useful statistical analyses are built. Good econometrics cannot save a shaky research agenda, but the promiscuous use of fancy mostly harmless econometrics pdf free download techniques sometimes brings down a good one. Like the biblical story of Exodus, a research agenda can be organized around four questions.
We call these Frequently Asked Questions FAQsbecause they should be. The FAQs ask about the relationship of interest, the ideal experiment, the identi…cation strategy, mostly harmless econometrics pdf free download, and the mode of inference. In the beginning, we should ask: What is the causal relationship of interest? For example, as part of a research agenda investigating human productive capacity— what labor economists call human capital— we have both investigated the causal e¤ect of schooling on wages Card,surveys research in this area.
The causal e¤ect of schooling on wages is the increment to wages an mostly harmless econometrics pdf free download would receive if he or she got more schooling. A range of studies suggest the causal e¤ect of a college degree is about 40 percent higher wages on average, quite a payo¤. The causal e¤ect of schooling on wages is useful for predicting the earnings consequences of, say, changing the costs of attending college, or strengthening compulsory attendance laws. This relation is also of theoretical interest since it can be derived from an economic model.
Causal questions can be asked about …rms, or, for that matter, countries. This study is concerned with whether countries that inherited more democratic institutions from their colonial rulers later enjoyed higher economic growth as a consequence. The answer to this question has implications for our understanding of history and for the consequences of contemporary development policy.
Today, for example, we might wonder whether newly forming democratic institutions are important for economic development in Iraq and Afghanistan. The case for democracy is far from clear-cut; at the moment, China is enjoying robust growth without the bene…t of complete political freedom, while much of Latin America has democratized mostly harmless econometrics pdf free download a big growth payo¤.
The second research FAQ is concerned with the experiment that could ideally be used to capture the causal e¤ ect of interest. In the case of schooling and wages, for example, we can imagine o¤ering potential dropouts a reward for …nishing school, and then studying the consequences.
In fact, Angrist and Lavy have run just such an experiment. Although this study looks at short-term e¤ects such as college enrollment, a longer-term follow-up might well look at wages, mostly harmless econometrics pdf free download. In the case of political institutions, we might like to go back in time and randomly assign di¤erent government structures to former colonies on their Independence Days an experiment that is more likely to be made into a movie than to get funded by the National Science Foundation.
Ideal experiments are most often hypothetical. Still, hypothetical experiments are worth contemplating because they help us pick fruitful research topics. Something like a well-funded Stanley Milgram, the psychologist who did path-breaking work on the response to authority in the s using highly controversial experimental designs that would likely cost him his job today.
Seeking to understand the response to authority, Milgram showed he could convince experimental subjects to administer painful electric shocks to pitifully protesting victims the shocks were fake and the victims were actors. This turned out to be controversial as well as clever— some psychologists claimed that the subjects who administered shocks were psychologically harmed by the experiment. The description of an ideal experiment also helps you formulate causal questions precisely.
