Office hours Tuesdays and Thursdays 3:00 – 5:00pm. Additional hours are available by appointment and can be scheduled by e-mail. Tracking me down in my office is another option but there are no guarantees I will be there. Communication E-mail is my preferred method of out-of-classroom communication. I will make every effort to answer all emails within 24 hours. Likewise it is your responsibility to check your @pitt.edu address on a regular basis as this is the address I have on file for all of you. I also have a mailbox in the department, it is located in the 4900 area (across from this classroom 4716) and is the one labeled ‘Bosworth’. Course description This course provides a rigorous introduction to the methodology of econometrics. Upon completion of this course students will have a deep understanding of: • What econometrics is • How economists conduct empirical research • The linear regression model • Estimation and inference using Ordinary Least Squares • Pitfalls of using OLS and how to avoid or work around them • Pulling causality out of correlation instrumental variables • Using computer software to programmatically work with data 1 Prerequesites You should be fairly comfortable with concepts from algebra and basic calculus. Furthermore, this course is heavy on probability theory and statistics. Having taken the 1000-level statistics course is a minimum. If the phrases “cumulative distribution” or “t-statistic” sound foreign to you; you should seriously reconsider your readiness to take econometrics. Textbook The text for this class is Introductory Econometrics: A Modern Approach 4e by Jeffrey M. Wooldridge. You must purchase this book, but a searchable pdf copy can also be found on my Dropbox account to which you will receive an invite from me at your Pitt e-mail. Software The homework and many in-class exercises will utilize the Mathematica software. You need not already know how to use this system, as it will be explained in-class. It should be installed in all campus computing labs. Furthermore, you may obtain a licensed copy for your personal Windows, Mac or Linux machine for $5 at Software Licensing Services in 204 Bellefield Hall. Class rules You are an adult. I do not have an attendance policy because I work off the assumption that you, as an adult, must have a perfectly valid reason for any absence from my class. My suggestion however, is that you attend every lecture. This semester is extremely compressed and we will cover a large amount of material in a very short time. Furthermore, while you are in lecture please refrain from distracting other students by talking, using your phone, texting, etc. Students with disabilities Any student with a need for special accommodation due to disability should inform me of this. The Disability Resources and Services Office (216 William Pitt Union, 412-624-7890) will coordinate the needed accommodations. Exams Dates of exams are contained in the detailed course schedule below. Exams will contain mostly problem-solving questions but may also include short writing responses. You may bring your notes and book to the exams. Exams are not cumulative. I will not offer make-up exams, with one exception: if you notify me or the department secretary as soon as possible of a serious reason (such as hospitalization) for missing an exam. This notification should be given prior to the exam. 2 Assignments There will be periodic homework assignments. Homework will not be accepted after 11:59pm on the due date posted. Homework is worth 13 of your grade, and will be very helpful in studying for the exams. You are allowed to work in groups, but everyone must turn in a copy of the assignment individually. Cheating I will monitor all tests very aggressively. Any student caught cheating will automatically fail the course, without exception. The university policies on plagiarism are well defined and I will follow them. Help The material of this course is highly cumulative. If you do not understand something, please seek help immediately. You are welcome to come to my office with questions about the general concepts presented in lecture; or to assist you in problem-solving skills required to complete a homework assignment. Grading Although attendance of lectures is not required, missing classes will seriously compromise your performance in this course. Your course grade will be computed with the following weights: Homework assignments Midterm exam Final exam 1 3 1 3 1 3 The course letter grade will be determined as follows: • after the final exam I will compute course scores incorporating scores earned on tests and homework weighted as indicated above • a student fails the class if the determined course score is below 50 • the rest are graded based on the following scale: 88–100 A range 75–87 B range 60–74 C range 50–59 D range • there may be curving to the extent that I reserve the right to uniformly add points (or not) to all exam scores; no points will ever be subtracted 3 Course calendar Week 1 2 3 4 5 6 Dates Jun 25 Jun 27 Jul 02 Jul 04 Jul 09 Jul 11 Jul 16 Jul 18 Jul 23 Jul 25 Jul 30 Aug 01 Lecture Review of statistics The simple regression model Multiple regression: Estimation No class – holiday Multiple regression: Inference & Asmptotics Midterm exam Multiple regression: Further issues Multiple regression: Qualitative information & dummy vars.

Course Description This course is an introduction to econometric methods from the perspective of users. The main goal of the course is to guide the student’s incursion into the application of econometrics to real-world problems. Econometric methods and techniques are always based on more or less realistic assumptions dictated by the need to reconcile the real-life constraints imposed by available economic data, with a coherent mathematical framework. In this course, students will learn to understand and interpret these assumptions in various empirical settings. The background knowledge needed to succeed in this course is college algebra and some elements of probability and statistics. But, the indispensable tools of probability and statistics will be taught as part of the course. Given the applied nature of the course, basic familiarity with computers is also required. Unless otherwise stated, the statistical package STATA will be used for most examples. Time and Classroom MW 3:00 PM - 4:15 PM, CL00358 Office Hour: Monday 9:50AM-10:50AM Textbook Jeffrey M.

These tools are useful for those intending to become quantitative business and economic analysts, and also, for those interested in knowing how economics is applied to real-world problems. The primary topic of the course is the linear regression model, which allows us to quantify the effect of changing one variable on another one. The course focuses on interpretation and estimation of parameters, as well as, hypothesis testing. These issues will be studied following an applied perspective. For this purpose, we can find many interesting questions such as: does reducing class size improve elementary school education? Is there racial discrimination in the credit market? We will employ the statistical package STATA, a computer software widely used in quantitative economic research. The background knowledge needed for this course is college algebra, basic probability, and elementary statistics. Textbooks Main Reference J. M. Wooldridge.

Pearson Prentice Hall, 2008. Requirements and Grading Policy The final grade will be based on six problem sets, two midterms, and a final exam. The weights are as follows. Problem Sets (20%): Six problem sets, each weights 3.33%. They involve the statistical software STATA, which will be taught during lectures. Students are allowed to submit their answers alone or in pairs. Problem sets will be due in hardcopy at the beginning of the class on the specified date. Midterms (40%): Two midterms, each weights 20%. The dates are Tuesday, February 25th, and Thursday, April 10th. Both are in-class. Final (40%): It is cumulative. All exams are closed-book and no calculators or any electronic devices are allowed. The only valid reason for missing an exam (or a homework) is serious illness to be verified in writing by a medical doctor. If you cannot make one midterm due to a serious illness, the final weights 60% instead of 40%. If you know that you cannot make the final exam on the specified date, you cannot take this course. Academic dishonesty will be handled according to the university regulations with no exceptions. Students must be aware of the University of Pittsburgh’s policy on Academic Integrity.1 1 This information is available at http://www.bc.pitt.edu/policies/policy/02/02-03-02.htm. 2 Disability Resources If you have a disability for which you are or may be requesting an accommodation, you are encouraged to contact both your instructor and the Office of Disability Resources and Services, 216 William Pitt Union, 412-648-7890/412-383-7355 (TTY), as early as possible in the term.

Although theoretical structures will be covered in some detail, the main emphasis will be on working with datasets and regression analysis in an effort to find relationships between variables that affect the world. Course Materials: Textbook: "Introductory Econometrics: A Modern Approach” 5th ed. J. Wooldridge CourseWeb: Check here often for assignments, exam dates, etc. Student Learning Outcomes: By the end of the course, students should be able to 1. Use statistical software programming (viz. Excel and STATA). 2. Use regression analysis to find the effects of variables on other variables. 3. Have a healthy understanding of the theoretical underpinnings of econometrics. 4. Understand and interpret the assumptions of econometric models in light of actual empirical applications. 5. Become proficient in the management of datasets. Course Policies Attendance: Although attendance will not figure directly into your grade for the semester, you are highly encouraged to attend class. You will be responsible for getting any notes or materials for any lectures that you miss. Office Hours: Students are encouraged to attend office hours to discuss any of the course content. If you are unable to meet during office hours, contact me so that we may coordinate another time to meet. Cheating and Academic Integrity: All students are expected to adhere to the standards of academic honesty. Any student engaged in cheating, plagiarism, or other acts of academic dishonesty would be subject to disciplinary action. Any student suspected of violating this obligation for any reason during the semester will be required to participate in the procedural process, initiated at the instructor level, as outlined in the University Guidelines on Academic Integrity http://www.pitt.edu/~provost/ail.html. This may include, but is not limited to the confiscation of the examination of any individual suspected of violating the University Policy. If you are caught cheating on an exam or an assignment, you will receive a zero on the exam or assignment. In addition, the event will be reported to the Office of Judicial Affairs, which may lead to additional actions from the University. Use of Electronics: The use of cell phones during lectures is a disrespectful distraction to your instructor and other classmates. Use of laptops for activities other than note taking is also distracting. Please turn your cell phones and electronic devices off while in class. In emergency situations, please discuss limited use of cell phone with me prior to the class during which you would like to use your cell phone. Email: My Pitt Email is typically the best way to get in touch with me. Try to plan ahead so that you can ask me questions well before any graded assignments are due. For example, please don't Email questions about problem sets and exams the night before they're due (or, if you do, realize that I might not be able to respond in time). Disability Services: If you have a disability, please contact me and the Office of Disability Resources and Services (DRS), 216 William Pitt Union, 412-648-7980/412-383-7355 (TYY) as early as possible in the term. DRS will verify your disability and determine reasonable accommodations for this course. Policy Regarding Missed Exams: Out of fairness to everyone in the class, exams are only given at the assigned time. If you cannot attend an exam due to a personal emergency outside your control, please let me know as soon as possible. Course Grades Your grade in the course will be a weighted average of problem set scores, papers, and two exams. The particular weights are given by Problem Sets and Papers: Midterm: Final Exam: 30% 35% 35% The exams will be based on material from the lectures and from the book. The exams will not be comprehensive. Note that the exams make up 70% of your grade. The final exam will be held on the last day of class (Thursday, April 17). Periodically, I'll assign problem sets relevant to the course material. Each problem set and written assignment will be equally weighted with respect to your grade. As a whole, problem sets will make up 30% of your grade. Your semester average will be converted to a letter grade according to the following table. Letter A AB+ B BC+ C CD+ D DFailure % 93-100 90-92 87-89 83-86 80-82 77-79 73-76 70-72 67-69 63-66 60-62 <60 ECON 1150: Applied Econometrics 1 (Summer 2014) University of Pittsburgh Department of Economics Instructor: Tate Twinam Email: tat47@pitt.edu Office: 4923 Wesley W.

If you wish, you can purchase your own copy of Stata/IC 13 for $98.00 online at http://www.stata.com/order/new/edu/gradplan.html Most students do not purchase their own copy of Stata. University Policies: We will adhere to the university’s Academic Integrity Policy in this class. See the University of Pittsburgh’s Undergraduate Bulletin or the Guidelines on Academic Integrity: Student and Faculty Obligations and Hearing Procedures at www.pitt.edu/~provost/ai1.html for full details on this. The Office of Disability Resources and Services, 140 William Pitt Union (412)648-7890 is available for students who have or may request an accommodation for a disability. If needed, please contact the office as early as possible in the term. Course Policies: Grading: Problem Sets Midterm 1 Midterm 2 Final 10% 20% 30% 40% Homework: There will be 8 or 9 problem sets which will be posted on the course website. Problem sets will not be graded. I will simply record whether you have turned each one in. I will also drop one, so that if you turn in 7 of 8 (or 8 of 9), you will receive full credit; if you turn in 4 out of 8 you will receive ½ credit, and so forth. I will not return the problem sets to you until the end of the term so that, if you are on the border between grades, I can refer back to them to break ties. Please take these assignments seriously. While solving the problem sets, you are allowed (in fact encouraged) to work in groups, as long as each group is comprised of no more than three people and as long as each member submits their own written answers. Problem sets should be turned in at the beginning of class on the day that they are due. Late homework will not be accepted and there will be no extensions. Exams: There will be no makeup midterms. If you miss a midterm for any reason, you must fill in the “missed exam form” that can be found on the course webpage and hand it to me within 7 days of the missed exam. Supporting documentation (if exists) can be attached to your form. I am not asking you, however, to disclose any personal information (e.g. medical records) if you wish not to do so. I’m going to assume that students follow the university’s academic integrity guidelines. The weight of a missed midterm exam will be reallocated to the final exam, regardless of the respective means of the individual exams. The final exam is comprehensive, so you will be responsible for all the material covered in this course. The time of the final is set and will not be moved under any circumstances. Exams will be closed book, but you will not need to memorize a bunch of formulas. For each exam, you will be given a set of formulas and notes prepared by me. I will post a copy of this handout before each exam so you know what to expect. Grading: This course will be graded on a curve. From my past experience, the median (not the mean) is a low B, although this could change if this class is particularly weak or strong. For obvious reasons (i.e. grade lobbying), the exact final cutoff points will not be disclosed under any circumstances (so don’t ask). I take objectivity and consistency in grading very seriously. The course policies outlined here apply to everyone: there will be no extra assignments, no reweighting of existing assignments, and no special consideration given to individual students who “feel their grade does not reflect their understanding of the material”. Re-grading: I work very hard to make sure that exams are graded accurately and fairly, but mistakes sometimes happen. If you think your exam should be re-graded, you have to submit in writing the detailed reasons why you think this is the case (unless your points have been added up incorrectly, in which case you can just bring the exam to me for an immediate correction). Take into account that if you ask for a re-grade, the entire exam will be checked again, meaning that you may lose points (since mistakes can happen in both directions). In addition, arguments for additional partial credit will not be considered: you must believe your answer is entirely correct as written. You must submit requests for midterm re-grades within one week of the day the exam was returned. Course Outline Note: The due dates for problem sets are tentative and will be subject to change. Refer to the problem set handouts and the course webpage for the final due dates.

Problem sets should be turned in at the beginning of class on the day that they are due. Late homework will not be accepted and there will be no extensions. Exams: There will be no makeup midterms. If you miss a midterm for any reason, you must fill in the “missed exam form” that can be found on the course webpage and hand it to me within 7 days of the missed exam. Supporting documentation (if exists) can be attached to your form. I am not asking you, however, to disclose any personal information (e.g. medical records) if you wish not to do so. I’m going to assume that students follow the university’s academic integrity guidelines. The weight of a missed midterm exam will be reallocated to the final exam, regardless of the respective means of the individual exams. The final exam is comprehensive, so you will be responsible for all the material covered in this course. The time of the final is set and will not be moved under any circumstances. Exams will be closed book, but you will not need to memorize a bunch of formulas. For each exam, you will be given a set of formulas and notes prepared by me. I will post a copy of this handout before each exam so you know what to expect. Grading: This course will be graded on a curve. From my past experience, the median (not the mean) is a low B, although this could change if this class is particularly weak or strong. For obvious reasons (i.e. grade lobbying), the exact final cutoff points will not be disclosed under any circumstances (so don’t ask). I take objectivity and consistency in grading very seriously. The course policies outlined here apply to everyone: there will be no extra assignments, no reweighting of existing assignments, and no special consideration given to individual students who “feel their grade does not reflect their understanding of the material”. Re-grading: I work very hard to make sure that exams are graded accurately and fairly, but mistakes sometimes happen. If you think your exam should be re-graded, you have to submit in writing the detailed reasons why you think this is the case (unless your points have been added up incorrectly, in which case you can just bring the exam to me for an immediate correction). Take into account that if you ask for a re-grade, the entire exam will be checked again, meaning that you may lose points (since mistakes can happen in both directions). In addition, arguments for additional partial credit will not be considered: you must believe your answer is entirely correct as written. You must submit requests for midterm re-grades within one week of the day the exam was returned. Course Outline Note: The due dates for problem sets are tentative and will be subject to change. Refer to the problem set handouts and the course webpage for the final due dates.

Email: My Pitt Email is typically the best way to get in touch with me. Try to plan ahead so that you can ask me questions well before any graded assignments are due. For example, please don't Email questions about problem sets and exams the night before they're due (or, if you do, realize that I might not be able to respond in time). Disability Services: If you have a disability, please contact me and the Office of Disability Resources and Services (DRS), 216 William Pitt Union, 412-648-7980 as early as possible in the term. DRS will verify your disability and determine reasonable accommodations for this course. Policy Regarding Missed Exams: Out of fairness to everyone in the class, exams are only given at the assigned time. If you cannot attend an exam due to a personal emergency outside your control, please let me know as soon as possible. Course Grades Your grade in the course will be a weighted average of problem set scores and three exams. The particular weights are given by Problem Set Average Exam I Exam II Exam III 25% 25% 25% 25% Thursday, Oct. 1 Thursday, Nov. 5 Thursday, Dec. 10 The exams will be based on material from the lectures and problem sets. The exams will NOT be comprehensive. Periodically, I'll assign problem sets relevant to the course material. Each problem set will be equally weighted with respect to your grade. Your semester average will be converted to a letter grade according to the following table. Letter A AB+ B BC+ C CD+ D DFailure % 93-100 90-92 87-89 83-86 80-82 77-79 73-76 70-72 67-69 63-66 60-62 <60 ECON 1150 - Applied Econometrics I Department of Economics, University of Pittsburgh Syllabus - Spring 2016 Instructor: Federico Zincenko, Ph.D. Lectures: Mondays and Wednesdays, 3:00pm - 4:15pm 358 Cathedral of Learning Office Hours: Tuesdays 4:00pm - 5:00pm, Wednesdays 11:00am - 12:00pm 4713 Posvar Hall e-mail: zincenko@pitt.edu Reader: Marli Wang Dunietz e-mail: mcw45@pitt.edu Course Description The goal of this course it to introduce basic tools in applied econometrics that are commonly employed in government, business, and academic research. Such tools are useful for those intending to become quantitative business and economic analysts, and also, for those interested in knowing how economics is applied to real-world problems. The primary topic of the course is the linear regression model, which allows us to quantify the effect of changing one variable on another one. The course focuses on interpretation and estimation of parameters, as well as, hypothesis testing. These issues will be studied following an applied perspective. For this purpose, we can find many interesting questions such as: does reducing class size improve elementary school education? Is there racial discrimination in the credit market? More generally, we study how to relate economic theory and real-world data. We will employ the statistical package Stata, a computer software widely used in quantitative economic research. The background knowledge needed for this course is college algebra, basic probability, and elementary statistics. 1 References Main Reference The course will be mainly based on my slides, which must be complemented with the following textbook: J.

A Brief Course in Mathematical Statistics. Pearson Prentice Hall. Requirements and Grading Policy The final grade will be based on six problem sets, two midterms, and a final exam. The weights are as follows. Problem Sets (20%): Six problem sets, each weights 3.33%. They involve using Stata, which will be taught during lectures. Students are allowed to submit their answers alone or in pairs. Problem sets will be due in hardcopy at the beginning of the class on the specified date. Midterms (40%): Two midterms, both are in-class. Highest grade midterm weights 25%, the other 15%. The dates are February 2 and April 11 (both are Mondays). Final (40%): It is cumulative and will take place on Saturday, April 30, from 4:00pm to 5:50pm. The room will be announced later. All exams are closed-book and no calculators or any electronic devices are allowed. The only valid reason for missing an exam (or a homework) is serious illness to be verified in writing by a medical doctor. If you cannot make one midterm due to a 2 serious illness, the final weights 60% (instead of 40%) and midterm you take 20%. If you know that you cannot make the final exam on the specified date, you cannot take this course. Course materials – such as slides, problem sets, and grades– will uploaded to the Blackboard: https://courseweb.pitt.edu/webapps/login. In the Syllabus section of this website, you can find statements regarding academic policies: academic integrity, disability services, accessibility, copyright notice, and statement on classroom recording. Students must be aware of all these statements. Among others, to ensure the free and open discussion of ideas, students cannot record classroom lectures. Academic dishonesty will be handled according to the university regulations with no exceptions. Disability Resources If you have a disability for which you are or may be requesting an accommodation, you are encouraged to contact both your instructor and the Office of Disability Resources and Services, 216 William Pitt Union, (412)648-7890/(412)383-7355, as early as possible in the term.
