SJSU Online Economics B.A. - Sample Econometrics Curriculum and Textbooks
SJSU classes started today on campus in San Jose, and online for our SJSU Online Economics B.A. students. Our SJSU Online program launched last Spring, and today we're welcoming our third cohort. In this post I'd like to share a little about my role in the development of the curriculum and content of our SJSU Online Economics B.A. courses, focusing on our Introduction to Econometrics and Research Methods course, ECON 103a.

YOU can use R in the cloud to do original research in less than a minute!
Here's a program in R that runs in the cloud and produces a CSV file with a table showing the most popular college majors and average earnings by major for any occupation.
UPDATE: Here's a video showing you how to use the program!
You can get a free Posit Cloud subscription and try out R without having to download R software or any data.
I tried to make running the code as easy as possible so someone with no experience with coding can run it, and then modify the code and rerun it. A user can select any occupation. Depending on what occupation they pick, it is quite possible no one has ever carried out the analysis before, so this program gives the user a chance to do real, original research. (In fact, the program generalizes the analysis done by John Winters in, "Is economics a good major for future lawyers? Evidence from earnings data," published in The Journal of Economic Education in 2016.
The instructions for using the file are embedded in the first lines of the code to the program linked to above, so click the link and give it a try today! Please leave a comment if you do!

Methods in Open Policy Analysis: An Application to California's Building Energy Codes
I have just posted a new working paper, "Methods in Open Policy Analysis: An Application to California's Building Energy Codes."
Abstract: Have building energy codes succeeded in lowering energy consumption, and have their benefits outweighed their costs? Using survey data from the 2000 US Census, I estimate household electricity and natural gas expenditures by decade of home construction, controlling for household and home characteristics, to study the impact of the first decade of California's energy codes. I then use the estimates in a social cost-benefit analysis (CBA) for a representative household. I find homes built in the 1980s used \$35 less in electricity and \$46 less in natural gas, per year, compared to homes built in the 1970s. For the Sacramento region, the energy codes pass a cost-benefit test (the present value of social benefits exceed compliance costs) when the best-case (low-end) policy cost estimates are used, but fail the test with base-case (mid-point) policy costs. This study paves the way for future analysis by clarifying how a CBA for a representative household fits into a comprehensive CBA.

Analyzing Donut Consumption in Springfield
Michael Bailey's econometrics textbook Real Econometrics begins in Chapter 1 with a small, 13-person data set consisting of characters from the Simpson's animated series (Homer, Marge, Comic Book Guy...). Although the variables are limited to weight and donut consumption (we can also infer gender from the names) it turns out one can use these data set to illustrate many of the core econometric techniques taught in an introductory, undergraduate econometrics course.
I've created two R scripts that contain code examples illustrating these fundamental techniques (such as displaying and summarizing data, calculating and comparing averages, bivariate and multivariate regressions with binary and continuous variables, nonlinear models, and producing tables and figures for use in word processing programs) all using Bailey's Simpsons data. The first one here is intended as an introduction and to help brand new students get started. The second one here illustrates more advanced techniques like nonlinear models and linear probability models.

Where do most people work from home?
The American Community Survey asks respondent how they usually get to work. In this post I examine these data, to suggest which metro areas are hardest hit by shelter-in-place orders. I also present statistics on which occupations are most likely to work from home.

Using R to select your college major
I have created a short video on using the script which you can find here.
Incorporating Published Research in Introductory Econometrics Courses
I'm currently writing a book that describes how to do this, but it won't be finished for another eight months. So for now, I am sharing R scripts, Stata do files and data sets needed to run some of the replications. My hope is to make it easier for instructors to include examples of real research in their classes.
At this link, I include links to the articles as well as replication files, and list the course topics and learning objectives that relate to each study.

Research data for The Impact of Urban Form on Vehicle Ownership
The data and code for this study are hosted at Open ICPSR. The Inter-University Consortium for Political and Social Research was conceived in the 1960s as a place where universities share data, and has thus been in the data game for a long time. In the past their data archiving has been more curated, and the new "Open" ICPSR is a new and exciting development. I plan to continue to use OpenICPSR to archive the research data for my projects.

Downloading Census Micro Data: IPUMS or Census.gov?
Most of the studies I include in the book use data from a database at the University of Minnesota called "IPUMS" (which stands for The Integrated Public Use Microdata Series.) It is also possible, at least for some years, to directly download the ACS data from the Census.gov web page. Which option is preferable? In this post I provide some answers to this question, as well as share a data file illustrating all the variables available by directly downloading the ACS data from the Census.gov webpage.

Replicating Costa and Kahn (2011)
A different question I address in this post is, can their results be replicated using what should be the same data obtained from a different source? It turns out it can and my R script is available here. This is a relevant question because for example sometimes data sets are updated (e.g. if errors are discovered). In addition, the data supplied by Costa and Kahn is only a small subset of the 2000 Census data, which only contains California homeowners in single-family homes. This is enough to reproduce their results, but it severely limits the types of extensions that one can do with their data (for example, if one wanted to estimate the baseline model on Florida households or for households in multi-family housing.)

University Scholar Series
The topic was Trends and Relationships Related to Air Pollution, Regulations, and Economic Growth.
This talk was recorded, and I will update this post with a link to the video once it becomes available. For now, I include a link to my presentation slides.
The first part of my talk stressed fascinating trends in U.S. transportation and residential selection patterns, especially the fall in driving and growth of cities over the last few years. I then discussed both my US and California research, and I briefly discussed my India research. Finally, I discussed some of my thoughts on SJSU's South Campus, an area that straddles some of San Jose's most beautiful parks, and some of the country's worst hazardous waste sites. Here I applied the results of my US and California research to make urban planning suggestions for San Jose.
As I mentioned, I will updating this post as soon as I have the link to the video. For now I'm glad to be done giving talks and teaching a while, and getting back to my India research!

Teaching Industrial Organization in Silicon Valley
Last night I gave the first lecture in our graduate IO course. I have taught the undergraduate version of this course more than a half dozen times, but this is only my second time for the grad class. For the first part of the class, the main textbook is Hal Varian's Intermediate Microeconomics with Calculus. Why is this a good choice for a IO class in San Jose, California?

A Review of Open Microeconomics Textbooks
I have used two of the three books in my own teaching, and in general I've paid close attention to this segment of the textbook market. As a result I am able to comment on not only the books themselves, but also developments in this industry. If you are an instructor considering adopting an "open" textbook, my review is for you.
If you are a donor who wants to support the development of open educaitonal resources, my review is also for you!
