Computational Topics in Economics and Econometrics Spring Semester 2003 Tuesday 12-2 Room 315 Christopher Flinn Room 302 Christopher.fl[email protected]
Computational Topics in Economics and Econometrics Spring Semester 2003 Tuesday 12-2 Room 315 Christopher Flinn Room 302 christopher.fl[email protected] Introduction: The objective of this course is to develop computational modeling skills that will increase the stu- dent’s capacity for performing quantiative research in economics. The basic premise of the course is the following. To adequately explain social phenomena of interest to economists requires the use of relatively sophisticated, albeit stylized, models. These models, whether involving only the solution of individual decision rules in a dynamic context or the determination of equilibria in a general equilibrium model, can only be solved numerically. We will review techniques that allow the solution of a large class of fixed point problems, which virtually all economic problems can be cast as, and will illustrate and compare techniques in the context of diverse examples. As an integral part of the course, students will be expected to contribute problems of their own, hopefully taken from current research questions they are investigating. We will also study the use of computational-intensive techniques in econometrics. Over the past several decades there have been a lot of exciting developments in this area due to enormous increases in processor speed and affordability. Topics in this area that we will treat include general computational issues in the estimation of nonlinear models, simulation estimation methods (maximum likelihood and method of moments), bootstrap methods, and the E-M algorithm. Examples from my own and other applied economists’ research will be used to illustrate the methods where appropriate. Because applied numerical analysis is at least one-half art form, it will be extremely useful for all of us to hear from individuals who have successfully completed large research projects that required them to solve daunting computational problems in the process. -

Simulating Inflation 1
Running head: SIMULATING INFLATION 1 Simulating Inflation: Is the Economy a Big Balloon? Ryan Heathcote A Senior Thesis submitted in partial fulfillment of the requirements for graduation in the Honors Program Liberty University Spring 2013 SIMULATING INFLATION 2 Acceptance of Senior Honors Thesis This Senior Honors Thesis is accepted in partial fulfillment of the requirements for graduation from the Honors Program of Liberty University. ______________________________ Mark Shaneck, Ph.D. Thesis Chair ______________________________ Terry Metzgar, Ph.D. Committee Member ______________________________ Monty Kester, Ph.D. Committee Member ______________________________ James H. Nutter, D.A. Honors Director ______________________________ Date SIMULATING INFLATION 3 Abstract Inflation is a common problem in modern economics, and it seems to persist, requiring government financial policy intervention on a regular basis in order to properly manage. The mechanics of inflation are difficult to understand, since the best metric modern society has for inflation involves taking samples of prices across the country. A simulation can give deeper insight into more than the mere fact that prices rise over time: a simulation can help to answer the “why” question. The problem with this statement is that developing a simulation is not as simple as writing some code. A simulation is developed according to a paradigm, and paradigms are not created equal. Research reveals that traditional paradigms that impose order from the outside do not mimic reality and thus do not give a good degree of accuracy. By contrast, Agent Based Modelling models reality very closely and is consequently able to simulate economic systems much more accurately.

The views expressed are those of the author(s). ABSTRACT In this paper we describe a step-by-step approach for the use of big data in nowcasting exercises and, possibly, in the construction of high frequency and new indicators. We also provide a set of recommendations associated to each step which are based on the outcome of the other tasks of the project as well as on the outcome of the previous project on big data and macroeconomic nowcasting. -

All Rights Reserved. 1 Some thoughts on debugging • As soon as we started programming, we found out to our surprise that it wasn’t as easy to get programs right as we had thought. Debugging had to be discovered. I can remember the exact instant when I realized that a large part of my life from then on was going to be spent in finding mistakes in my own programs. – Maurice Wilkes • Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it. – Brian W. Kernigan • Sometimes it pays to stay in bed on Monday, rather than spending the rest of the week debugging Monday’s code. – Dan Saloman © 2017 Rogue Wave Software, Inc.
