...e YOUR ECONOMETRICS PAPER BASIC TIPS There are a couple of websites that you can browse to give you some ideas for topics and data. Think about what you want to do with this paper. Econometrics is a great tool to market when looking for jobs. A well-written econometrics paper and your presentation can be a nice addition to your resume. You are not expected to do original research here. REPLICATION of prior results is perfectly acceptable. Read Studenmund's Chapter 11. One of the most frustrating things in doing an econometrics paper is finding the data. Do not spend a lot of time on a topic before determining whether there is data available that will allow you to answer your question. It is a good idea to write down your ideal data set that would allow you to address your topic. If you find that the available data is not even close to what you had originally desired, you might want to change your topic. Also, remember that knowing the location of your data – website, reference book, etc – is not the same as having your data available to use. It may take a LONG time to get the data in a format that EVIEWS can read. Do not leave this till the last minute. For most data, I enter the data into Excel first. I save the Excel sheet in the oldest version, namely MS Excel Worksheet 2.1 . The reason is that format can be read by most programs whereas newer formats may or may not be read. Eviews easily reads an Excel sheet 2.1 version. You should use...

Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.1 or any later version published by the Free Software Foundation (see Appendix F for details). i Preface The previous edition of this manual was about using the software package called gretl to do various econometric tasks required in a typical two course undergraduate or masters level econometrics sequence. This version tries to do the same, but several enhancements have been made that will interest those teaching more advanced courses. I have come to appreciate the power and usefulness of gretl’s powerful scripting language, now called hansl. Hansl is powerful enough to do some serious computing, but simple enough for novices to learn. In this version of the book, you will find more information about writing functions and using loops to obtain basic results. The programs have been generalized in many instances so that they could be adapted for other uses if desired. As I learn more about hansl specifically...

...1. In the population model: cigsi = βo + β1educi + ui a) Interpret the coefficient β1. β1 represents the slope of the regression line and is the change in cigs associated with a unit change in educ. So for one unit increase of educ there will be β1 units increase/decrease (depending on the sign of β1) in the cigs. b) Can you predict the sign of β1 (without doing any estimation)? Explain. The sign of β1 would most probably be minus looking at the information from the surveys in the excel spreadsheet. The education value is always a positive number (educi > 0), βo is also a positive number (the intercept with y, as cigsi >=0). In this way in order for the number of cigarettes to be equal to 0, the β1 value should be negative. 2. Use the data in SMOKE.sav (see Blackboard) to estimate the model from question 1. Report the estimated equation in the usual way. Also, plot a handwritten graph of the estimated equation. cigs = 11,412 – 0,219 educ 3. Does educ explain a lot of the variation in the number of cigarettes smoked? Explain. The regression R2 is the fraction of the sample variance of cigsiexplained by (or predicted by) educi. In this example R2 equals to 0,002 and this amount is closer to 0, which means that the regressor educ is not very good at predicting the value of cigs, thus does not explain a lot of the variation in the number of cigarettes smoked. 4. Find the predicted difference in number of smoked cigarettes for two people...

...empec, Vol. 13, 1988, page 223-249 Nonparametric Estimation and Hypothesis Testing in Econometric Models By A. Ullah ~ Abstract: In this paper we systematically review and develop nonparametric estimation and testing techniques in the context of econometric models. The results are discussed under the settings of regression model and kernel estimation, although as indicated in the paper these results can go through for other econometric models and for the nearest neighbor estimation. A nontechnical survey of the asymptotic properties of kernel regression estimation is also presented. The technique described in the paper are useful for the empirical analysis of the economic relations whose true functional forms are usually unknown. 1 Introduction Consider an economic model y =R(x)+u where y is a dependent variable, x is a vector o f regressors, u is the disturbance and R(x) = E ( y l x ) . Often, in practice, the estimation o f the derivatives o f R(x)are o f interest. For example, the first derivative indicates the response coefficient (regression coefficient) o f y with respect to x, and the second derivauve indicates the curvature o f R(x). In the parametric econometrics the estimation o f these derivatives and testing 1 Aman Ullah, Department of Economics, University of Western Ontario, London, Ontario, N6A 5C2, Canada.

It is one of the few courses that explicitly covers empirical methods, i.e., the analysis of observed economic behavior in the form of data. Empirics stand in contrast to theory, e.g., micro and macro, about how agents behave. Despite this under-representation, empirical analysis comprises a large part of economists’ workload and is one of the most practical skills that an economics student can learn. Course Objectives In this class students will: 1. perform statistical and practical inference based on the results of empirical analysis, 2. identify useful characteristics of estimators, e.g., unbiasedness, consistency, efficiency, 3. state predictions of theoretical economic models in terms of testable hypotheses, 4. model economic relationships using classical methods, such as Ordinary Least Squares, derive the properties of estimators related to these methods, and 5. perform estimation using methods discussed in class using software, 6. perform diagnostic tests that infer whether a model’s assumptions are invalid, 7. evaluate empirical models based on whether their resulting estimators...

...Principles of Econometrics Tips for a Term Paper Topic Your work MUST BE ORIGINAL, but the issue/model/methodology need not! Money/Macro/International Economics Common Approaches 1. Apply a model or law (e.g., Phillips curve, Okun’s law, etc.) to more recent data. 2. Extend what is known for the U.S. to other countries (emerging, developing or Eastern European). Examples: 1. Outsourcing: Do firms that outsource tend to do better? Or why they outsource? 2. Trade deficit: What causes the huge US trade deficit? 3. Twin deficits: Is there a link between the trade deficit and the government budget deficit? 4. Foreign exchange: What has caused the recent drop of the US dollar? 5. Oil shocks: Have oil shocks led to recessions in the US or elsewhere? 6. Growth: Why some countries are rich while others poor? 7. Election: What determines an election outcome? 8.

...International Conference On Applied Economics – ICOAE 2010 299 DOES STOCK MARKET DEVELOPMENT CAUSE ECONOMIC GROWTH? A TIME SERIES ANALYSIS FOR BANGLADESH ECONOMY MD. SHARIF HOSSAIN (PH. D.)1 - KHND. MD. MOSTAFA KAMAL2 Abstract In this paper the principal purpose has been made to investigate the causal relationship between stock market development and economic growth in Bangladesh. To investigate long-run causal linkages between stock market development and economic growth the Engle-Granger causality and ML tests are applied. In this paper another attempt has been made to investigate the non-stationarity in the series of stock market development and economic growth by using modern econometric techniques. The co-integrated tests are applied to know whether this pair of variables shares the same stochastic trend or not. From our analysis it has been found that the stock market development strongly influences the economic growth in Bangladesh economy, but there is no causation from economic growth to stock market development. Thus unidirectional causality has prevailed between stock market development and economic growth in the Bangladesh economy. Also it has been found that all the variables are integrated of order 1, and both the variables stock market development and economic growth share the same stochastic trend in Bangladesh economy.

...Impact of Education on Growth 27.05.2015 Applied Econometrics İpek Tuğrul 15415 İpek Tuğrul 15415 27.05.2015 Term paper: Impact of Education on Growth As a basic theory which is always taught in economics, the effect of education on the economic growth of a country is always positive. In order to further verify this theory, the authors of many books provide examples which complement it. If we go deep into this theory and search for other evidence, we come across different researches done by economists and statisticians who have analyzed the theory to a great extent. In order to differentiate their studies they have done their empirical research on the subject by using different econometric models. Even though the underlying result i.e. derived from their research is the same, yet these models have different comprehensive implications, something which will also be discussed in our review. As a part of our review we have taken four different research paper written by different researchers, which have the same fundamental scope. However, the origins of these researches are subject to geographical changes and this has been done in order to prove our basic rationality of the theory. The critical reviews consist of the methods used by the authors and the way they have tried to analyze the empirical evidence by using econometric models. The first article which we will be reviewing in our...
