I finished my 50 miler, and in fairly good shape, too. It took just about 3 hours 20 minutes, which is a bit more than I expected.
I'd hoped to take it easy for the first 30 miles or so, but there were a couple of hills (one at 5 miles, and another another at 17 1/2) that were pretty stiff. Since my heart rate was up to 160 by the top of each hill, I knew I was in for a long ride. Then, to add insult to injury, there was another hill at about 30 that felt like I was riding up a telephone pole for about 2-300 yards. Oh, what fun.
Ah well - next year I'll know to spend a lot more time working on hills beforehand (it's flat enough near Unknown University that I don't see a lot of hills unless I want to).
The legs aren't too bad right now, but I can tell tomorrow will be a real treat.
Next stop - a century!

Another Good Ride
I did a 34 mile ride today - my longest so far this year. I've been using a heart monitor for a couple of years, and every year, it takes me a while to realize that I should pay attention to it - when I keep my pace slow enough in the early miles that my heart rate stays below 135 or so, a couple hour ride becomes pretty easy.
About time - my ride for the Hole in the Wall Gang Camp is only 7 days away.

Stick A Fork In Me!
I'm done, done, DONE with grading for the semester. Now there's nothing left to do but wait for the complaints. Ah well - that I can deal with.
For a reward, I spent the night spent reading an anthology of short stories titled Strange Brew by P.N. Elrod (author of the Vampire Files). It includes stories by some of my favorites, including Jim Butcher, Patricia Briggs, and Charlaine Harris, among others (what can I say - I'm a big fantasy/sci-fi nerd).
On the biking side, there's been nothing but rain for the last few days, so I went to the gym to use the exercise bike for about 40 minutes. It's a poor substitute for having wheels on the road, but my 50 miler (the Angel Ride) is only 11 days ahead, so it's better than nothing.
Enough goofing off - back to research.
Update: The rain stopped, so I got in another 26 miler. I rode like a circus bear on a bike, but I was still within a minute of my best time, so I'll take it. The good news is that I seem to be able to handle at least that distance at a pretty good pace even on an off day. So, with a bit more work, I should be able to do the 50 if I dial back a bit. It won't be pretty, but it's a ride, not a race.

It's Time To Bring The Crop In
It's that time of the semester - exams are done, projects are in (with one exception) and it's grading time. Some highlights/low lights:
Unfortunately, yesterday involved a pretty hard 26 miler followed in short order by my 1 1/2 hour "Yoga For Stiff Guys" class (fairly strenuous yoga done in a heated room). BY the end of the day, I was beat to the bone.
Oh well - back to grading those last few student projects.
- My Student Managed Investment fund was a weak group, and they never seemed to "get with the program". As a result, they did a lot of the work for the end-of-semester presentation to our advisory board in the 11th hour.
- Having said that, they did a pretty good job in the presentation. Not as good as last year's group (that was probably my strongest group in the last 5 years), but good enough
- My Investments class did terribly on my final exam. On the one hand, it means that grades will be lower than expected. On the other, since grades will depend a lot on the curve, it allows me a lot of flexibility.
- I have THREE students that will be returning for my student-managed investment fund class next semester (they're three of the better ones, too). This makes my job a lot easier.

FMA Decisions Are Out!
I just heard from a coauthor - we got a paper accepted at the Denver FMA meeting in October. The idea resulted from taking an idea we'd been working on and applying it to another data set we had available.
It's funny - we submitted two papers: this one was an early version, and the other was pretty much finished. However, to be fair, the results on this one were more interesting. And since we'd already gotten one paper on the program, we were actually glad we got the second one rejected - doing two papers at a conference means there's less time for catching up with friends.
This tale of two papers reminds me of a piece I read a while back (unfortunately, I can't recall its title). It discussed how there's a trade-off in research between "newness" and "required rigor". In other words, if you're working on a topic that's been done to death (e.g. capital structure or dividend policy), you'll be asked to do robustness tests out the yazoo. On the other hand, if it's a more novel idea, there's a lower bar on the rigor side, because the "newness" factor gets you some slack on the rigor side. .
In general, however, the "rigor" bar has been ratcheting up for the last 20-30 years, regardless of the "newness" factor. To see this, realize that the average length of a Journal of Finance article in the early 80s was something like l6 pages - now it's more like 30-40. As further (anecdotal) evidence, a friend of mine had a paper published on long-run returns around some types of mergers in the Journal of Banking and Finance about 9 years back. They made him calculate the returns FIVE different ways.
In any event, to make a long story short, I'm hoping we got accepted at FMA because the reviewers though our paper was a good, new idea.
But it's probably because we got lucky.
But either way, we'll take it - see you in Denver!

Journal Of Undergraduate Research In Finance
There's a new journal out geared towards undergraduate research. It's called (appropriately), The Journal of Undergraduate Research In Finance. Here's it's description:
The Journal of Undergraduate Research in Finance publishes original work written exclusively by undergraduates. Accepted articles are largely the result of the highest quality senior or honors theses. Articles come from all areas of Finance, case studies and pedagogy. All articles are subject to blind review by faculty.So, if you have a student who has done some good research and who might be looking for an outlet, have them send it in - the submission deadline for this year's edition is May 15. As an added inducement, the top three articles for this year's issue will be invited to the FMA meeting in Denver to present their research, and will be considered for the annual Mark J. Bertus prize (in the amount of $1,000).The JURF exists to encourage exceptional undergraduate students to pursue high quality research in Finance, to provide these students with an outlet for their research, and to prepare these students for success in graduate school or industry. To maintain a focus on contributions made by the students, faculty involvement is limited to the guidance typically given during the writing of a senior thesis. Initial submissions must be made while the author is an undergraduate student.
The JURF is published annually.

The Default Major
A colleague just pointed out a great article in the New York Times, titled "The Default Major". Here's a few choice pieces:
These sound like things I've heard my own colleagues say in the hallways at Unknown University.
Nothing new. But somehow, there are professors in my school (several come to mind without much effort) who hold the students to high standards AND get top evaluations. The common threads in their classes is that they DEMAND that students come to class prepared and cold-call from day one. And they make classroom performance (either measured by the quality of participation or by numerous in-class quizzes (often of the unannounced, "pop quiz" variety) a major part of the grade.
Of course, they work a lot harder than the other professors in the classroom, but DUH.
Students will slack, not go to class, and cheat like crazy if all the instructor does is read off PowerPoint slides and give softball take-home assignments. They're rational, after all.
I view the course design (of which the grading scheme is a major part) as a mechanism design problem. In other words, it's an exercise in putting together a grading scheme that forces the students into behaviors that I want them to engage.
For the most part, they're rational - they'll find a way to get the grade they want while minimizing effort. The trick is to set the class up so that they can't slack. Unfortunately. that's harder than the old "30% of the class grade is based on the mid-term, 50% on the final, and 20% on quizzes" structure.
But it's possible.
Business majors spend less time preparing for class than do students in any other broad field, according to the most recent National Survey of Student Engagement: nearly half of seniors majoring in business say they spend fewer than 11 hours a week studying outside class. In their new book “Academically Adrift: Limited Learning on College Campuses,” the sociologists Richard Arum and Josipa Roksa report that business majors had the weakest gains during the first two years of college on a national test of writing and reasoning skills. And when business students take the GMAT, the entry examination for M.B.A. programs, they score lower than students in every other major.Let's see - the students don't study as much, they minimize effort, cheat on take-home exams, and don't come to class prepared.
...
Donald R. Bacon, a business professor at the University of Denver, studied group projects at his institution and found a perverse dynamic: the groups that functioned most smoothly were often the ones where the least learning occurred. That’s because students divided up the tasks in ways they felt comfortable with. The math whiz would do the statistical work, the English minor drafted the analysis. And then there’s the most common complaint about groups: some shoulder all the work, the rest do nothing.“I understand that teamwork is important, but in my opinion they need to do more to deal with the problem of slackers,” says Justin Triplett, a 2010 Radford graduate who is completing his first year in Radford’s M.B.A. program. From his perch as a teaching assistant, he estimates that a third of students in the business school don’t engage with their schoolwork. At Radford, seniors in business invest on average 3.64 hours a week preparing for class, according to the National Survey of Student Engagement.
...
One senior accounting major at Radford, who asked not to be named so as not to damage his job prospects, says he goes to class only to take tests or give presentations. “A lot of classes I’ve been exposed to, you just go to class and they do the PowerPoint from the book,” he says. “It just seems kind of pointless to go when (a) you’re probably not going to be paying much attention anyway and (b) it would probably be worth more of your time just to sit with your book and read it.”
How much time does he spend reading textbooks?
“Well, this week I don’t have any tests, so probably zero,” he says. “Next week I’ll have a test, so maybe 10 hours then.”
He adds: “It seems like now, every take-home test you get, you can just go and Google. If the question is from a test bank, you can just type the text in, and somebody out there will have it and you can just use that.”

Another Good Ride
It was another nice day today (but windy as all get out). So, I did another 17 1/2 mile ride. Yesterday, my feet were freezing (it was about 50 degrees). Today, it was warmer (no need for a jacket), but the wind was brutal - over 20 mph at times.
Still, it was good, and about 5 minutes faster than yesterday for the same course. I was pretty tired after yesterday's ride, but the forecast says rain for the next few days, so I figured I'd take the ride when I could get it.
I must have gone harder than I thought, because about three hours later, I got a hamstring cramp of truly biblical proportions. Luckily, the Unknown Family was out of town, because I actually yelled (and loudly)
But given the chance, I'd take the ride again if I could. It's biking season!

The First Ride of the Season
Up until the last two weeks or so, I've been getting up at least 5 days a week at 4:30 and working out at the local YMCA from 5-6 (mostly spinning on the stationary bike). As a result of this and watching my diet, I've dropped about 15 pounds since the beginning of the year. So, I'm about the same weight at the beginning of biking season that I usually am around mid-Jul. I was wondering how this would translate to actually being on the road.
Today I found out - I took my first ride of the season, and went about 17 1/2 miles (about twice what I usually do at the beginning of the season). Despite the relative cold (about 52 and windy as all get out), it was pretty easy - I was able to keep my heart rate under 150 pretty much the whole way (except for the last 50 yards of a steep half-mile long hill at the 8 mile mark). So, it looks like it'll be a good riding season.
I'll be riding in the Angel Ride, a 50 mile fund-raiser for the Hole In The Wall Camp over Memorial Day Weekend, so I need to get with it. It's actually the second day of a two-day ride where they go the length of northern Connecticut (from the northwest corner to the northeast corner - about 80 miles) the first day, stay at the camp over Saturday night, and ride down the eastern border of Connecticut (northeast to southeast - about 50 miles) the second day. I'll be as part of a group that includes two guys from my weekly bible study and a lady from my wife's grief group (she lost a daughter to cancer a couple of years ago).
And finally, there's only three weeks left to the semester - yeah, baby!

Finance Videos Online
As I've mentioned before, I'm a big fan of using pre-recorded videos as resources for my students. I've been wondering if they would be attractive to others.
I recently came across a site called MindBites - they provide a platform for the distribution of video content online. Basically, they're an iTunes-type store for instructional videos. So, I uploaded my tutorials (so far, only the first two) for the Texas Instruments BA 2+ calculator, and priced them at $0.99 each (pretty much an iTunes model). I'm curious to see if anyone buys them.
Since I'm already putting much of my core Introductory Finance Class into short videos as a resource for my students, I'll post them to the Mindbites site as well. I figure there might be someone who's willing to pay a few bucks for (as an example) a series of 5 videos (about 3 hours alltogether of lectures on Time Value (with examples for using the calculator, the formulas, and Excel spreadsheets). If not, at least I'll have them done for my classes.
In case you're interested, the videos can be found here. If you decide to download them (the site takes PayPal), leave a review.
