Is your MBA tax deductible?
Although the line of Tax Court cases considering the deductibility of MBA related tuition expenses may at first appear to be a confusing and winding maze of inconsistency, more careful inspection reveals that—in most cases—the courts probably got it right. For the most part, MBA students at elite schools who attempted to take enormous tax deductions for career-transforming educational experiences were turned away, whereas those toiling away in an effort to improve their established business skills while continuing to work full-time were permitted to take their deductions. In short, at the end of the day it appears as if the courts generally muddled through the cluttered, outdated mess that is Treasury Regulation § 1.162-5 and came out with the right answers.

Samsung TV USB Media Player: Tips and Troubleshooting
The TV supports a variety of video file formats, such as AVI, MP4, MKV, and VOB. These are really just "containers" for audio and video information, so just because you have one of these files there's no guarantee that the TV will play it. Within the container, the audio and video is stored using a codec. Common video codecs are Divx, Xvid, and MPEG4. Common audio codecs are AC3, MP3, and DTS. You can use software like VLC to tell what codecs were used to create a particular file.
Not supported audio codec
MKV has become popular with high definition material (720p, 1080p). However, the most common problem when you try to play an MKV file is that the video works but the error message comes up: "Not supported audio codec" and there is no sound. Most of the time, this is because the audio was encoded with Digital Theater System (DTS) which the TV doesn't support (Samsung didn't want to pay the license fee). You can easily fix this by reencoding the file to Dolby Digital (AC3) using PopCorn Audio Converter.
Dialog is not in English
MKV files often contain more than one audio track. However, the TV has no way to select between the tracks, so if the default audio track is not the one you want, you can't change it while you're watching. First, open the file with VLC to make sure there is an English language track in the file. Then, open the file in MKVmergeGUI (part of MKVtoolnix) which will allow you to select exactly which audio track you want, and create (aka "remux") a new file that has only that audio track.
It is possible that a file could have both problems - DTS audio and a primary non-English track. In that case, first remux a new MKV using mkvmerge with only the audio track you want. Then, run it through the DTS to AC3 conversion.
The TV won't display subtitles
Just as an MKV file can contain more than one audio stream, it may also contain subtitles, however the TV doesn't support this subtitle format. First, extract the subtitles from the file using MKVExtractGUI. Then, run the output through Subtitle Workshop to convert to SRT format which the TV supports. Make sure you name your new SRT file exactly the same as your MKV file (except for the file name extension, which will obviously be different: .SRT versus .MKV) and put it in the same directory as the video file. Then, you can activate the captions using the CC button on the TV's remote control.
Archiving your DVDs to a hard drive
With 1TB hard drives available for under $100 now, you might want to backup your DVD collection. This would allow you to play any of your movies off the hard drive without having to search for the discs. However, if you try to just copy the files off your DVD and play them on the TV, you probably won't get what you're expecting, even though the TV supports VOB files. The file may not play at all, or the video will start and end in weird places. This is because the DVD menu also contains instructions on where the video should start and stop, but the TV doesn't know how to read that data. The solution is to use DVDShrink to remaster the DVD and extract just the video you want. This will work for both a movie that is one big file as well as a DVD with TV shows on it, where you want a separate output file for each episode. Put the DVD in the computer and start DVDShrink. Select the Re-Author function and then select the various video tracks that you want to extract. Select Backup to copy those files to your hard drive. Now you can open each of those VOBs will be a self-contained video file that the TV can recognize.

Puerto Rico: Day 4
We drove into Old San Juan and took a tour of Fort San Felipe del Morro. Old San Juan is a nice place to visit but very touristy. One fun attraction was the Don Q rum tasting room near the cruise ship terminal. Who doesn't like free samples of rum? Dinner at Pal Cielo was excellent...a funky little place that we wouldn't have otherwise found except for our host's recommendation. Great ceviche.

Puerto Rico: Day 2
Leaving the hotel, we drove to Fajardo to catch the afternoon ferry to Vieques. We didn't have any trouble getting a seat, and for $2 it's a lot cheaper than flying. We left our rental car at the ferry terminal and hoped it would still be in once piece upon our return. Martinque Car Rental picked us up at the ferry and took us to their office, where we rented a Jeep Wrangler that had definitely seen better days. Surprisingly, we had a hard time reserving a car, most of the places were booked up several weeks in advance. It was a short drive to the Esperanza Inn. Our room was a nicely furnished apartment that had air conditioning (thank goodness) and a television. The owners were very friendly and gave us a hand when we had trouble starting our rental car. We spent the rest of the evening walking along the Esperanza beach plaza.

The Sovereign Ceiling
The sovereign ceiling says that the private sector should not be able to borrow on better terms than the government, since the government has the most senior claims on the firm's earnings (priority ahead of both debt and equity). If the government runs into economic trouble, it may be more likely to expropriate assets. Additionally, the government's problems may reflect broader economic issues that will also impact the firm. Therefore, lenders should not offer better terms to a private company than they would to its host country. The country's credit rating is a cap on all firms' credit ratings.

The foreign profits tax "loophole"
Scenario 1: You're an individual investor and who buys a share of stock in Toyota in January for $100. Over the course of the year, the company earns $5/share in pre-tax profit. They pay corporate taxes of 20% on their earnings, so your share of the after-tax profit is $4. The local government collects $1/share in tax revenue. The company pays no dividend and reinvests those $4 profits into developing new products, hiring workers, expanding factories, etc. At the end of the year, your share is now worth $104. You haven't sold your share, so your profits are unrealized, and the tax you owe is $0, because although your investment is worth more on paper, you haven't actually received any cash. You have deferred your tax burden until you either sell the shares or receive a dividend.
Scenario 2: You're a corporation who buys a small company that owns several companies in Estonia for $100 million. Over the course of the year, the subsidiary earns $5 million in pre-tax profit. They pay corporate taxes of 20% on their earnings, so your share of the after-tax profit is $4 million. The local government collects $1 million in tax revenue. The company pays no dividend back to the US and reinvests the $4 million profit into developing new products, hiring workers, expanding factories, etc. At the end of the year, your investment is now worth $104 million. Your company in the US hasn't received any cash or profits and under the current system you wouldn't owe any additional tax on top of what the subsidiary already paid the local government.
However, if the tax laws were changed to make foreign income taxable, you would have to immediately pay US taxes on the entire $5 million, even though the parent corporation never received any cash from the foreign subsidiary - all the cash and profits were either paid in the first round of local taxation or reinvested in growing the company.
This is a highly simplified example. Obviously there is a distinction between normal foreign earned profits and truly abusive tax shelters in some countries that should be eliminated. But this example shows that foreign earned profits are not much different than profits earned on other similar investments. So is it equitable to treat them differently? Investors who have a 401k or IRA also take advantage of tax deferral - is that a "loophole"?

"Over 400 years ago Shakespeare explained that to take out a loan one had to negotiate both the interest rate and the collateral level. It is clear which of the two Shakespeare thought was the more important. Who can remember the interest rate Shylock charged Antonio? But everybody remembers the pound of flesh that Shylock and Antonio agreed on as collateral. The upshot of the play, moreover, is that the regulatory authority (the court) decides that the collateral level Shylock and Antonio agreed upon was socially suboptimal, and the court decrees a different collateral level. The Fed too should sometimes decree different collateral levels."

Cap-and-trade market structure, lessons from the past

First, the credits were initially distributed to natural shorts (e.g. a power plant that produces SO2) that expected to use them at some point in the future. Except for relative emissions reductions (a plant installs a better scrubber and thus needs fewer credits), most of the market participants will stay long the credits to offset their natural short exposure. Thus, incentives to trade are reduced and the market is less liquid. Lower liquidity means that small changes in supply or demand can have a magnified effect on price.
Second, the credits were distributed for free, and were held on the firms' balance sheet at zero tax basis. When a credit is redeemed, the increased value is recognized as a gain, but offset by the increased environmental liability from generating the SO2, so it's a wash for tax purposes. If a firm believed the price spike was temporary, it could sell some of its banked credits while prices were high, then buy them back once the market returned to normal, netting a profit. But this action creates a taxable gain today, while the liability is still off in the future. The potential gains from this arbitrage must be weighed against the acceleration of the tax liability.
Third, many of the firms with credits are publicly regulated utilities. If the firm were to profit from selling credits high and buying them back low, regulators might force the firm to pass the profits along to customers (rather than letting shareholders and management keep them). On the other hand, if the arbitrage failed and the firm lost money, regulators might view this as speculation and punish management for being imprudent.
Thus, the owners of SO2 credits failed to create a viable market for them. Note that financial intermediaries, such as the much maligned short sellers and speculators, could help provide liquidity to a market like this and thereby enable more efficient price discovery, reducing the risk of disruptive price spikes.

Encyclopedias and the Pace of Change
Last week, Microsoft announced that they are shutting down Encarta, the digital encyclopedia that was originally released on CD-ROM. A brief history:
- 1778-1993 (215 years): Encyclopædia Britannica rules the day
- 1993-2009 (16 years) Microsoft's Encata quickly takes over
- 2009-?: Volunteer-edited Wikipedia ascends to the throne
The question is, how long will Wikipedia reign? If the average lifespan of encyclopedia technology continues to shrink at the speed implied above, a challenger may already exist. Ironically, Microsoft helped force Britannica's capitulation by giving away free copies (excuse me, "bundling") of Encarta when you bought a new computer with the Windows operating system. Wikipedia's product managed to undercut them on price while offering greater value and a lower cost of production.

Trop50: An Orange Juice Ripoff
I spotted a container of Trop50 at the store and although it is the same shape and price as the regular Tropicana ($2.96), the Trop50 package is 8% smaller by volume (64 ounces versus 59 ounces). The problem compounds when you flip the carton around and notice the statement "contains 42% juice." The back panel reveals that the primary ingredient is water, followed by reconstituted orange juice, then some vitamins, and finally stevia (a non-sugar "natural" sweetener). So Trop50 expects you to pay an 8% premium for a product that contains 58% less juice (58% more watered-down) than regular OJ?
Here's a cheaper alternative: fill your glass halfway with regular orange juice, then add water until it's full (cost per 12 oz serving: $0.28). Or, buy Trop50 (12 oz for $0.60), and pay a 117% premium for the 30 seconds it will save you in the morning.
