  1. Hello, I’ve just finished my first year of a BSc Economics degree at Warwick University. I’ve been dead set on a PhD in Economics in the US for a while, and I’m aiming for the top 5. However, I don’t feel like my undergraduate degree is helping me. Although I can take a limited number of modules from the maths department, I don’t feel like I’m getting enough maths to be competitive at the top programs. I have the option to switch to BSc MMORSE (essentially maths, stats and economics), which allows for far more mathematical/statistical/econometric modules to be taken while not sacrificing much economic theory, although it would take me two years longer. I’m struggling to come to a decision on whether to switch. I’ve performed well in my first year (estimated top 0.5-1%), but worry that even if hypothetically every other part of my application was exceptional, it would be undermined by my lack of maths. I realise how hard it is to get into a top 5 program especially with a non-top 10 undergrad, but I’m serious in my ambitions. Do you think the value placed by the top PhD programs on mathematical preparation justifies the obvious financial/social costs of switching? Thank you!
  2. Hey guys, I am currently a 2nd-year Master's student at a top 5 college in my country. Type of Undergrad: Engineering in Electronics & Communication from a virtually unknown Asian university. Undergrad Percentage: First Class (62%) Math Courses: Maths - I, Maths - II, Maths - III (covered Linear Algebra, Calculus, Numerical Methods) : First class with distinction Master's degree - 1st year GPA : 8/10 Relevant Courses: Micro 1 - 9 (A+) Macro 1 - 8 (A) Micro 2 - 8 (A) Statistics - 9 (A+) Econometrics - 6 (B) :( GRE : 160 V, 166 Q, 4 AWA Internship Experience: Worked on applied micro Letters of Recommendation: Three good letters. My current program is specialized in environmental economics, but here on I am interested to pursue research in economic theory or macroeconomics. Will my econometrics grade significantly hurt my chances? I am trying to compensate for the low grade in this semester's econometrics course but I won't have that on my transcripts when I apply this year. Do I have a shot at any of the top 50 US programs or should I try getting some research experience first before applying? I am not so keen on enrolling for another Master's program since time and money both are a constraint. Which schools should I be looking at? Any other suggestions are also welcomed. Thank you!
  3. Hi I am doing a degree in economics and applied maths and took a total of 14 maths and stats courses. Out of those all except for 4 are As (As in many proof based courses like functional analysis, ODEs, Complex Analysis, Real Analysis). I have Cs in PDEs, Bayesian Inference, Stochastic Processes and Stochastic Simulation. Three of those were because of poor health during prep and exams and I missed the deadline to apply for a resit. I m definitely going to retake PDEs and stochastic processes wherever I do my pre-doc/just any uni close to me that offers the course because I know that those courses are important. Do I need to retake the bayesian and stochastic simulation courses as well? I honestly can't be bothered to do it. Also what do you think about my overall profile in terms of maths prep? I have strong As in all my Econ courses. Thank you
  4. How to Solve: LCM, GCD and Properties of LCM and GCD Hi All, I have recently uploaded a Video on YouTube to discuss LCM and GCD in detail. Following is covered in the video: What is LCM and how to find LCM of 2 or more numbers using three methods. What is GCD and how to find GCD of 2 or more numbers using three methods. • Listing Out Multiples • Common Division Method • Prime Factorization Method How to find LCM and GCD of Exponents and Fractions. Properties of LCM and GCD Prop 1: LCM of 0 and any number does not exist • LCM ( 0 , a ) = Does not exist Prop 2: GCD of 0 and any number is equal to the number itself. (Because all whole numbers are factors of 0. So, a will be also be a factor of 0.) • GCD ( 0 , a ) = a Prop 3: LCM of 1 and any number is equal to the number itself • LCM ( 1 , a ) = a Prop 4: GCD of 1 and any number is equal to 1 • GCD ( 1 , a ) = 1 Prop 5: Product of two numbers = Product of their LCM and GCD • a*b = LCM(a,b) * GCD(a,b) Prop 6: LCM of two numbers is always a multiple of their GCD • LCM(a,b) = GCD(a,b) * k [where k is an integer] Prop 7: LCM of two numbers always lies between the larger of the two numbers and the product of those two numbers • Larger (a,b) Prop 8: GCD of two numbers is always smaller than or equal to the smaller of those two numbers • GCD (a,b) Prop 9: LCM of two numbers is equal to the larger of the two numbers when one number is multiple of other • LCM(a,b) = Larger(a,b) => either a is a multiple of b or b is a multiple of a Prop 10: LCM of two numbers is equal to the product of those two numbers when the numbers are co-prime • LCM(a,b) = a*b => a and b are co-prime numbers Co-prime numbers are numbers which have only one factor in common (i.e. 1) Prop 11: GCD of two numbers is equal to the smaller of the two numbers when one number is multiple of other • GCD(a,b) = Smaller(a,b) => either a is a multiple of b or b is a multiple of a Prop 12: GCD of two numbers is 1 when the numbers are co-prime • GCD(a,b)=1 => a and b are co-prime numbers Prop 13: All numbers can be written as a multiple of their GCD • a and b can be written as a multiple of their GCD • a = GCD(a,b) * k [where k is an integer] • b = GCD(a,b) * t [where t is an integer] Prop 14: All multiples of LCM are divisible by the numbers whose LCM we have calculated • Multiples of LCM(a,b) will be divisible by both a and b Prop 15: a + b and a -b will always be divisible by GCD(a,b) • a+bGCD(a,b)=k [where k is an integer] • a−bGCD(a,b)=t[where t is an integer] Sample Word Problems: Prob 1: Joe has 12 A-grade projects and Chris has 18 B-grade projects. They have to divide up the projects into small teams with equal number of projects in each team; each team can have either A-grade project or B-grade project only. If there is no remainder, find the largest possible number of projects in each team. Prob 2: Joe and Chris were each given a piece of wood of equal length. Joe cuts his wood piece into equal lengths of 12 cm, while Chris cuts his wood piece into equal lengths of 18 cm. If there was no remainder in both cases, find the shortest possible length of wood given to them. Prob 3: Two steel pieces of length 340 cm and 408 cm are to be cut into pieces of all the same length without remainder. Find the greatest possible length of the pieces. Solutions: Prob 1: GCD (12,18) =6 Prob 2: LCM(12,18) = 36 Prob 3: GCD(340,408) = 68 Ankit

  7. Hi guys, I'm currently an undergraduate student at Oxbridge, studying CS & Maths. Recently, after doing a research project in game theory, I have been reading various texts and taking online courses (MIT OCW, etc.) in economics, and I'm finding it extremely interesting so far. I might be thinking too many steps ahead, but I would like to make a transition to economics; I would like to continue on to a PhD program, preferably in the US (I always wanted to take on postgraduate studies, it feels like economics is the one). I've come to know that a lot of programs look favourably upon students with heavy maths and programming background, but also that they expect at least some previous exposure to economics at the undergraduate level. Yet, as I'm studying in the UK, I'm only doing courses in maths and computer science, and quite likely that I will need to do a masters degree to match that expectation. I have been more or less in the top 15-20% of my cohort (trying to get those up), and my coursework includes (this list could get much longer if I continue on to 4th year): (Maths) Linear Algebra, Groups, Real Analysis, 2 years of Probability Theory, Multivariable Calculus, Differential Equations (ODEs and PDEs), Complex Analysis, Topology, Statistics, Functional Analysis, Probability and Measure, Stochastic Calculus, Dynamical Systems, Differential Geometry and more (CompSci) Object Oriented Programming, 2 years of Algorithms, Computational Complexity, Machine Learning, Computational Game Theory, and more (I cut down some courses rather irrelevant) What would be some possible pathways for me to get into Top Econ PhD programs? Should I do a masters degree in economics (e.g. LSE EME, Cambridge Diploma then MPhil)? Or does anyone have other suggestions? Realistically speaking, what would be my chances? Thank you everyone! I would hugely appreciate any advice.
  8. Hi everybody, I'm finishing up a BSc in maths in Denmark, and I wish to do a phd in economics in the US. I currently hold offers from Oxford - MSc in Mathematical Sciences (1 year) LSE - MSc Economics (2 years) Imperial College London - MSc Pure Mathematics (1 year) Which of the options will be a better gateway to a phd in econ in the US? All the best
  9. Hi everyone I'm finding it difficult to guess where I stand in terms of application strength as my background might be a bit disadvantageous when it comes to applying for PhDs in economics since I didn't have room in my degree to do any foundational economics units. Would like to know what sort of schools I should be applying for. I don't think my profile is strong enough for US top 15, maybe top 50? Should I consider doing a masters in economics first? PROFILE: Type of Undergrad: Pure maths, with some bioinformatics and philosophy from an Australian university. I guess top tier but we don't really care about that much down here. Undergrad GPA: 6.71/7 (about a 3.8), 1st Class Honours in Mathematics (this is comparable to summa cum laude but with a research thesis) GRE: Q 166, V 168, AWA 5 Math Courses: 3 semesters of analysis, 1 semester of probability, 6 semesters of algebra/geometry, some applied maths, other random maths courses Econ Courses: 1 reading course on economics Other Courses: Bioinformatics, philosophy, Letters of Recommendation: Honours maths thesis supervisor, worked together for a year, thesis was in combinatorial algebra/ solving a problem in linear algebra Maths professor I worked with for half a year as a teaching assistant, Final letter writer will likely be a professor who knows me fairly well but also in maths! Research Experience: Honours thesis in algebra: 1 year 4 research courses I did in my undergrad: each one lasted a semester. none of these are in economics. Teaching Experience: Got a job as a tutor for a first year course in my second year of uni. I've been doing that for three years. Research Interests: Development economics, mathematical economics Concerns: I reckon my lack of a strong econ background definitely sets me back. Is there anything I can do about this at this stage? Looking to apply this year. Thank you for any advice
  10. Undergrad- Delhi University (Top Univ in India/Average college )Scored 53% (a below average score) Scored approx 50% in the maths courses (Maths for Economics -1 and 2,Linear Algebra and Calculus ) (It's a kinda a long story though luckily I was able to wriggle myself into a masters course by placeing well in the Entrance exam.) Currently pursuing my M.A. Economics from an average program in my country(India). It's currently my first semester and I would like to pursue research in Behavioral/Experimental Economics. The reason I say that it's an average program is that although the faculty is reasonably renowned (in my country at least) and has considerable publication ,the university itself has only been founded in 2008. I will have an option to write a dissertation in my second year.However any other quality research experience would be hard to find. What can I do to increase my chances of getting into a decent P.h.d. course upon my completion in 2019? Would aiming for Top 30 be too high ?
  11. Hi, I am a candidate from India. I have done business administration at both undergraduate and graduate levels specialising in Finance (BBA and MBA). I have also completed two levels of CFA. I am planning on pursuing a PhD in Finance but I do not have sufficient math background. After speaking with several people (past and current PhD students, and Professors) I have come to the conclusion that I need to do a Masters in order to bring my math skills up to scratch. I have gone through a lot of posts and have a fair idea of the kind of quant courses that are required of PhD finance students. Although I have taken courses in Statistics, Econometrics and Probability, I understand that the level at which these courses were conducted is not considered very competitive, especially to do research. I have no college level Calculus at all. So, my question is, which Masters should I pursue? I could not see a lot of MFin courses that taught the kind of math courses that were required of a PhD candidate. Should I go for an MS in Stat or Economics? Are there colleges that offer specialised courses for this very purpose? I saw that TAMU was one. Any information on this would be very helpful. Please keep in mind that I am an International candidate and options like taking courses in the evening at a local US university is probably ruled out because I would need to be enrolled full time in a course to get a student visa. 1) MS in Stat or Economics or anything else? 2) Any university or college that offers specialised courses for people like me? Thanks!
  12. Hey everybody, I almost finished my Bachelor's in economics in Maastricht and I am thinking of where to go for Master's program. I definitely want to do something much more technical than in my Bachelor's program; either something like mathematical economics or econometrics (financial econometrics but I am not definitely sure yet). With that I mean that I really want to do more abstract and complicated maths including mathematical proofs, abstract reasoning, etc. I am looking for a top (research) Master's program (2year) and I plan to go to top 20 US school afterwards I know that there are already lots of threads here but I still couldn't find definite answers, especially about the level of tinbergen's advanced econometrics track. GPA: 9/10 GRE quant: 168 What is the best address for Master's program in econometrics (financial econometrics) or mathematical economics in Europe? I applied at LSE, Cambridge, Oxford already. But I am also interested in Bonn, Mannheim, Tinbergen Institute and Tilburg University. What are the chances to go from the German and Dutch unis to top20 grad school in US for PhD in economics? And how technical are these degrees? I heard Bonn and Mannheim are quite good and technical. However, Bonn and Mannheim are both rather weak in Econometrics. Anyone knows more about how good they are in econometrics? I also heard that Tinbergen is very good at econometrics because of its technical and rigorous econometrics track? Anyone has any experience with it? Is it possible to do as "normal" economics graduate to do the "econometrics" track? Or is it too hard? Thank's for your help!!!!
  13. Hello guys, Please i need a bit of advice. I am not very good at maths and i want to pursue a PhD in Economics. How long do you think i have to prepare to be ready before i embark on this journey. My first degree and Msc were both in Economics but during those times i really struggled with it. I am not confident enough that i am good enough in maths. Thank you.
  14. Is there a formula to figure out the number of Primes between two given integers? Let's say if I have to find total number of Prime numbers between 19 & 79.
  15. What is the square root of 4? Is it -2 & 2 or simply 2? -2 x -2 = 4 2 x 2 = 4
  16. Can you come up with a series of 3 consecutive integers in which none of them is divisible by 3?
  17. Please let me know if there is a simple method to solve problems dat involve Mixture and proportions. How do u solve - In what proportion must 3 types of wheat be at Rs.127, Rs. 129 & Rs. 132 respectively be mixed to produce mixture worth Rs. 132??
  18. Sorry, if this has already been answered somewhere else. Why is 0! = 1? n! = n x (n-1) x (n-2) x........ x 2 x 1 How do we put 0 in the above formula and get value 1? Thanks
  19. Hi! I came across this - "The square root of a negative number is not a real number."
