scientists 5quot Explain four core ideas that de ne way economists think about macroeconomic questions i Explain why economics is worth studying I Economics is the science ofchoice the science that explains the choices that we make and how those choices change as we cope with scarcity Society s wants exceed the resources available to satisfy them l Rich and poor alike are faced with scarcity

edition Required What has been ordered is a package that comes with the text the text itself a printed study guide and access to the website econFoundations with exercises sample quizzes and various support materials and to online and phone tutorial support Note If you buy a used secondhand copy of the book it probably won t have an access number that works any more for the website however you can buy the access separately for 30 online at the website beginning in January This is the publisher s way of encouraging you to buy a new book Target Copy has a packet that contains an expanded version of the PowerPoint slides I use in class in note form 6 slidespage on one side of the page threeholepunched so you have blank pages to write notes on The packet should cost under 15 many students nd it convenient to buy it put it in a threering binder and bring it to class to make notes directly without having to copy the slides Alternatively you can download the slides in 3 or 6 slidespage form from the web see below There is no need to bring the text or studyguide to class Objectives This course is an introductory survey of economics with main focus on macroeconomics and the international economy At the end of the course you should be able to critically read and discuss an article on economics in serious media such as the Wall StreetJournal New York Times or Business Week Forbes or The Economist understand and express in normal language the jargon and reasoning of an economic statement or argument distinguish fallacious plausible and unknowable assertions about the economy Requirements and Grading Your grade will be based on three elements 1 lnclass Exams three midterms 18 20 and 22 of course grade respectively on Thursday 31 January Thursday 7 March and Thursday 11 April 2 A comprehensive nal 25 of course grade on Tuesday 23 April 300 500 p m 3 Best eight 2 minute cointoss quizzes 15 of grade Each class we will at some point during the class toss a coin to determine whether to do a 2 minute quiz so there should be about 12 of them We will do the quizzes at a random time during class to discourage people showing up near the end for the quiz only and with the seating in Moore you had better not try to leave after we do it The quiz questions will be based on closely parallel to a question from the study guide or econFoundations website on the material we are covering that day Each 2 minute quiz is scored out of 2 points 2 for a substantially right answer 1 for a wrong answer zero for absent To repeat the best eight count scaled to 15 of the total course grade Typically the final scale for the class is such that the difference between maximum and minimum points on these twominute quizzes 15 points out of a hundred is equivalent to more than a full letter grade This is deliberately designed as a an incentive for you to come to class however boring I am research shows students who attend class do better and b an incentive to actually use the study guide andor the econFoundations website Exams will be multiple choice There is no preset point score equivalent of letter grades the scale gtcurve is determined after the test on the basis of performance by the class as a whole 1 use and grades Make sure you understand how your grade will be determined 1 do not permit any form of extra credit Your grades during the semester will be accessible through a gradeengine on the course website If you are unable to be present for a scheduled midterm exam for a legitimate reason you must inform Dr Cobbe in advance and request alternative arrangements e g earlier time for a test greater weight on the other two quizzes if possible emergencies on the day of the test CALL 644 7091 N0 makeups 0r alternatives permitted after the event if you miss the test without my permission beforehand Because only the best 8 count no makeups on twominute quizzes If an excused absence prevents you from taking a scheduled midterm and you cannot do it early the weight on that 1 midterm will be given to the other two midterms equally You cannot have a makeup after the test has been given Unexcused absences translate into zeroes If you are taking both ECO 2013 and 2023 this semester both should have their nal at the same time check your 2023 syllabus If so you need to either take both nals in the same time slot one after the other or one on Tuesday and the other at the scheduled makeup time on Friday of exam week 26 April at 530 pm Consult Dr Cobbe after Spring Break you will need a written permission slip to take the makeup General Housekeeping Notes 1 make heavy use of email if you dont have an FSU garnet email address already get one at once If you prefer to use a nonFSU email address there is an easy way to forward your FSU email to the other address fill out the form at htggsregisteracns fsueduCARSforwardhtml You must have an FSU email address and then forward because the course mailing lists are generated from registration data and only include FSU email addresses 1 check my email frequently and in general you should get a reply within 24 hours usually much quicker The course email list has address ECO201302garnetacns fsuedu email sent to that address goes to everyone registered for the class and me If you want to send email to me only not to everybody in the class use the address jcobbecoss fsuedu The material in this class is mostly cumulative i e it builds on what has gone before We move quite fast there are 20 chapters in the main textbook and we will cover all of them although not all the material in all chapters email will tell you what you can pay less attention to it is important not to get behind at the beginning and to keep up throughout With a twiceaweek only class there are only 25 class meetings other than exams you cannot afford to miss much material The text package gives you lots of alternatives for practice and learning make use of them If you work this stuff it will help you on quizzes and exams More generally if you are having trouble with the course ASK FOR HELP B contact one of the TA s go to the help room see below or see Dr Cobbe in office hours If you have already taken ECO 2023 the first three weeks chapters 1 7 4 are going to be mostly if not wholly review 7 material you have seen before Do not be lulled into a false sense that the whole course will be easy most people find ECO 2013 more difficult than ECO 2023 There will be a regular weekly help session in room BEL 0004 on Wednesdays 515 7 630 p m You are not required to attend and you get no extra credit for doing so but if you have questions or problems this is an opportunity to come ask for further explanation and hear what other people are having trouble with Review sessions will be scheduled before the midterms assuming a room can be obtained details will be provided by email and in class The Department of Economics has a help room for all its lower division courses The room is 146 W113 and will be open 11 am to 4 p m and 630 pm to 730 pm Monday through Thursday and 11 am to 3 pm Friday depending on usage opening times might be adjusted later in the semester The room will be staffed by economics graduate student TA s and will have materials for all the 2000level courses in the Department and some PCs for the websiteCD material You will be emailed with the times that my TA s will be working in the help room but if you have a courserelated economics question rather than a question about your grade you can go there anytime it is open 7 all the graduate students staffing the room should be able to answer your questions The location is 146 W113 146 William Johnston Building But it is hard to find There is a brick arched walkway by some dumpsters about half way from Landis Green to Ivy Way between the side of W113 and the side back of Reynolds Hall There are double doors with windows into WJB in that walkway 146 is just inside first door on the right Each class is 75 minutes 200 to 315 that is the price you pay for only meeting twice a week 1 will try to break the 75 minutes up by having you do things during it butl will normally try to use the full 75 minutes This is not the nicest room please do me and your fellow students the courtesy of not leaving early or arriving late that is disruptive for others The classes are anchored around lecture material keyed to the PowerPoint slides but we should be coming out of the slides and doing other things a lot of the time If we are spending too much time on the slides and you are getting bored or sent to sleep let me know Economics is about I 39 39 but also about r 39 The A A that come with this text package are quite good and can be very helpful for understanding and absorbing the material ifyou use them The course will also use the web to post material of various kinds The home page for the course is httpmailerfsueduNjcobbe 13502htm39 1 also leave up on the web material from earlier semesters which you can browse if you want start from httpmailerfsueduNjcobbeec02013htm A longer version of the PowerPoint slides thatl use in class will be posted to the web in 3 and 6 slideperpage note format you can download if you wish I believe there is also a version of the PowerPoint slides on the eFoundations website but they are not quite the same and I prefer mine Do not imagine that if you have the text and the slides you have the whole course and don t need to come to class because the slides are available to you 1 will tend to go through them fast and 1 mean to do lots of things that are NOT in the slides Class time can maybe help you begin to understand the material reading the book and the slidesnotes will help too yes it really does but the only way to fully get it is to be able to do it B which is where the eFoundations website and Study Guide can really help you Many people find it both less unpleasant and more productive to work software or other exercises with one or two others rather than alone I encourage you to do that try to find a couple of other people in the class with whom you can form a little study group and meet regularly to do the exercises and talk about the material B for most people that works better than just studying alone The schedule below is somewhat tentative because this is a brand new book B it may turn out that we go a bit faster or slower in places and we may not have time to cover everything on this initial outline I will email the class where we are in the book and what the coverage is for the midterm exams on a regular basis The Department of Economics strongly endorses the Academic Honor Code and any instance of academic dishonesty detected will lead to severe academic penalties at least an un droppable zero for any graded item in question If you have any doubts as to what is or is not academic dishonesty consult the Student Handbook or ask ADA Statement If you have a disability requiring academic accommodations 1 Inform Dr Cobbe as soon as possible preferably during the first week of class bringing a letter from the SDRC confirming your need for academic accommodations 2 Discuss the accommodations you need with Dr Cobbe39 it is your responsibility to ensure that he has adequate notice to arrange such accommodations Tentative Schedule 1 T 8 J Introduction Chapter 1 2 R 10 J Chapter 1 continued39 Also the
