I am not teaching this course right now, but I have left links to my notes and other course materials below. Hopefully, you or someone else will find them useful. A word of caution however:  Like everyone else, I make mistakes. I am aware of most of the errors, but I simply haven't had time to fix them.

     Course Requirements
     
    Your final grade will be determined by a weighted average of a mid-term exam (35 percent), a final exam (45 percent) and the quality of your class participation (20 percent). 

    The exams will consist of a section of identifications -- in which you will write brief definitions and describe the relevance of key concepts, theories, etc. -- and a section of essays. 

    Homework will be assigned and the solutions will be reviewed in class, but I will not collect them and I will not grade them. If you read the Lecture Notes and the textbook do the homework regularly, you will develop a good understanding of the course material and you will score higher on the exams. If you only read the Lecture Notes and do the homework the night before the exam, don't expect to pass. 

    Finally, in evaluating the quality of your class participation, I will consider: 

    1. your attitude towards the course material,
    2. how well you demonstrate an understanding of the required readings and homework assignments and
    3. how often you ask intelligent questions in class. 
    Saying "I don't understand" and explaining what you don't understand and why you don't understand it is one of the most intelligent things you can do. It demonstrates curiosity and interest in the course material. 
    By contrast, sitting in silence when you don't understand is one of the dumbest things you can do. 
     
    Course Textbook
     
    • Doviak, Eric. Lecture Notes on Economic Growth and Economic Fluctuations. -- click HERE
    • a custom textbook that I designed with the assistance of McGraw-Hill (available in the bookstore)
    • Pearce, David W. (ed.) The MIT Dictionary of Modern Economics. ISBN: 0-262-66078-4 (???)

      •  
    My Lecture Notes contain a lot of information, but they are not a substitute for a textbook. You need a textbook for depth. I recommend the custom textbook because it covers the material in the Lecture Notes in far greater depth than my Lecture Notes and more intuitively than other textbooks do. 
     
    Why Study Macroeconomics?
     
    Macroeconomics is the study of how economies perform over short and long periods of time. This is an important discipline because the performance of an economy is directly tied to living standards. After all, the more our economy produces, the more we can consume and the higher is our standard of living. 
     
    Similarly, if an economy is producing less output this year than it did last year, our consumption in this year will likely be lower than it was last year and the number of unemployed workers will likely be higher than it was last year. 
     
    Macroeconomics also examines the impact that government policy can have on the rate of unemployment, the level of output that our economy produces and the prices that we pay for the goods and services that we consume. 
     
    Of fundamental importance is the time frame in which we are examining the economy's performance. Many of the government policies which boost our living standards over short periods of time are downright harmful to our living standards over longer periods of time. 
     
    This course places a great emphasis on the difference between the short-run and long-run performance of the economy and stresses the tradeoffs that government policymakers face. For example, raising taxes and cutting government spending is political suicide, but one day we will have to pay off the government debt and that will require either tax hikes or cuts in government spending. 
     
    Studying such tradeoffs will help you understand the nature of tradeoffs that you face in everyday life. 
     
    For example, in the short run, spending time studying economics prevents you from spending time with family and friends. In the long run, time spent studying economics will enable you to make more rational decisions, which will increase your productivity at the office and -- hopefully -- enable you to get a raise. 
     
    Objectives of this Course
     
    This course has two sets of objectives: practical and academic. The practical objectives aim to teach you how to apply mathematics and economics in daily life. The academic objectives (which are listed with the class schedule) aim to teach you basic macroeconomics. 
     
    The practical objectives consist of: 
    • enabling you to interpret graphs and equations, both mathematically and intuitively,
    • developing your logical thinking skills,
    • teaching you how independent variables affect dependent variables and
    • helping you apply the concept of opportunity cost, marginalism and efficient markets in everyday life.
     
    Knowledge of algebra is a prerequisite. I will conduct a review of basic algebra, but it's meant to be a review, not an opportunity to learn it for the first time. If you are unable to grasp the concepts I cover during the math review, I will advise you to drop the course -- not because I'm cruel, but rather because I don't want you to suffer for four months and fail. 
     BlackBoard 
      
    I won't use BlackBoard much in this course, but there may be times when I would like you to read materials other than the Lecture Notes or the textbook. In such an event, I'll post the articles to BlackBoard. 
     
    • So go to:  http://www.cuny.edu
    • At the bottom of the orange column on the left-hand side is a "Log-in" link. Click there.
    • On the next page ... If you already have a Portal Login, just enter your username and password.
     
    If you don't have a Portal Login yet, then click the "Register Now!" link and the system will verify your status by using your last name, Social Security Number, date of birth, etc. 
     
    • After you have logged in, you'll see a "My Page" window with a whole bunch of bubbles. In the bubble in the upper left ("SSO Applications for Faculty and Staff"), there is a link to "BlackBoard." Click on that link.
    • On the next page, you'll be asked to choose your CUNY school. Select the Brooklyn College link and you'll be taken to another screen with a whole bunch of bubbles.
    • In the "My Courses" bubble, you'll see a link to the Macro course. Click on that link and you'll finally be in BlackBoard.
    • All of the files for the course are in the "Course Documents" page, which you can get to by clicking on the "Course Documents" link in the green column on the left-hand side. 
      
    Attendance Policy
     
    Come and go as you please, but keep in mind that the lectures are an important part of the course. If you're not here, it's going to be a lot harder to understand the course material. Poor attendance will also adversely affect my evaluation of your class participation. 
     
    For example, if you never come to a single class, but somehow manage to ace both exams (which is highly unlikely), your final grade would be a B-plus - that's 80 percent of an A (4.0). 
     
    Exam Make-Up Policy
     
    Any student who is either unable to attend class on the day of the exam or simply doesn't feel like coming to class on the day of the exam, doesn't have to come. There's no need to contact me or explain the reason for your absence. Just don't come. 
     
    If you miss the mid-term exam, you will be expected to submit a take-home examination within two weeks of the class immediately following the mid-term exam. No exceptions. 
     
    If you miss the final exam, you will have to make it up during departmental exams next semester. 
     
    In deciding whether or not to come to class on the day of the exam, keep in mind that I see absolutely no reason why the difficulty of the take-home exam or the departmental exam should be comparable to that of the in-class exam. 
     
    If I were in your shoes, I would come to class on the day of the exam. 
     
    Instant Replay Rule
     
    If you do not do well on an exam and would like to improve your grade by doing the make-up exam, I'll look very favorably upon your efforts. 
     
    For those of you who would like to improve your grade by haggling with me over points, we'll play by the "Instant Replay Rule." If your complaint has merit, I'll fix your grade. If your complaint does not have merit, it will cost you one whole letter grade. 
     
    Email at your Own Risk
     
    Any take-home assignment (such as a make-up exam) should be submitted to me during regular class hours. If you cannot attend class that day, ask a friend to submit it for you. 
     
    I will also accept assignments submitted to me by email or left in my box at the Economics Department Office (Whitehead 217). 
     
    Keep in mind however that email does not always work perfectly. There is a low (but not insignificant) probability that the email will not be delivered to me. There is also a low (but not insignificant) probability that an assignment left in my box will disappear. 
     
    I will not be held accountable for vanishing emails. Nor will I be held accountable for assignments devoured by the mailbox gremlin. You assume ALL of the risk associated with email and/or mailbox submissions. If I don't receive it, it's your problem, not mine. 
     
    Policy on Cheating 
     
    Don't even think about it. I will catch you and I will pursue the harshest penalty that the college allows. 
     
    What you should think about is the reputation of your school. If Brooklyn College were to develop a reputation for tolerance of cheating, then potential employers would consider completion of a degree at Brooklyn College to be a trivial accomplishment and your investment of time, money and energy at this school will have been squandered. 
     
    Use of notes during an in-class exam is cheating. Don't do it. Copying material from a website on a take-home exam is cheating. Don't do it. 
     
    If you think I won't know if you copied material from a website on a take-home exam, you're wrong. 
     
    What to Expect
     
    I have an easy-going attitude, but don't expect an easy A. I work hard and I expect the same from you. 
     
    I'll give you all the help you need, but don't expect me to spoon-feed you the answers. This is college. Come prepared to ask me questions. Don't waste my time. 
     
    I don't see things in black and white. I am incapable of answering a question with a simple "yes" or "no." I look for the complexity in an issue and seek to understand it. 
     
    If you get impatient with someone who takes their time to answer a question or goes into too much detail, then I'm probably not the professor for you. 
     
    On the other hand, if you want to learn how to analyze an issue and come to a well-reasoned conclusion, then you're in the right place.
