Why a Financial Transaction Tax Is a Bad Idea

<em>This article was originally posted on TabbForum <a href="http://tabbforum.com/opinions/associate-professor-university-of-alaska-anchorage">here</a></em> By Holly A. Bell Former Secretary of Labor Robert Reich claims financial transaction taxes are simply sales taxes on Wall Street traders and won’t harm markets or cause capital to flee. Yet studies of FTTs in other countries show they harm Main Street and distort markets. Former Secretary of Labor Robert Reich recently produced a snappy video about why financial transactions taxes (FTTs) as proposed by Bernie Sander’s on the campaign trail should be retained and turned into law. Unfortunately, his pithy presentation is wrought with inaccuracies. He begins by modifying the language of FTTs by shruggingly telling us it’s just a sales tax. We pay sales taxes on many things and it’s only “fair,” he claims, that anyone who sells a stock should pay a tax too. Yet it’s not exactly like a sales tax. For one thing, it’s not transparent.

The Potential Effects of Reg AT: Unintended Risks and Diminished Cooperation with Market Participants

Ill-considered regulation regarding algorithmic trading will adversely affect the ability of legitimate market participants to contribute to liquidity, price discovery, narrow spreads, and low trading costs. The CFTC shares with market participants a growing interest in algorithmic trading and its potential effects on the markets. Rather than working with market participants cooperatively, the Commission proposes a prescriptive regime applicable to virtually any firm that trades in the futures (and swaps) markets. If finalized, this proposal will establish an approach dominated by enforcement that will chill firms’ willingness to work with the Commission to address emerging problems in the area. In addition, by opening firms’ source code to unlimited inspection by the Commission and others, the proposal creates dangerous vulnerabilities for an asset of utmost importance to trading firms. <strong>To see full article click <a href="http://mercatus.org/publication/potential-effects-reg-unintended-risks-and-diminished-cooperation-market-participants">here</a></strong>

…and then one morning you wake up and you’re a reference on Wikipedia

Life is weird sometimes. I had a pretty great week last week. I got to go to Chicago early in the week to speak at a conference on high-frequency and algorithmic trading and meet a lot of interesting--and frighteningly smart--people. I always enjoy getting my nerd on with other academics and policy wonks especially when combined with industry experts and a guy who started university at 14 and now builds neural networks to create artificial intelligence-type systems to trade stocks. For about 2 1/2 minutes I was even able to hold my own in a conversation with him about how his systems handle outliers in their outputs. Being in Chicago also allowed me to enjoy their freakishly warm 70-degree temperatures while Alaska was experiencing slick roads due to freezing rain and snow. Upon returning home I received another speaking invitation and an offer to be a guest on Reuters Global Markets Forum.
