The university formerly known as NUI Galway (and before that, UCG) rebranded as University of Galway last year.

This post outlines how you can make beamer slides to match the university branding. The theme is called Gaillimh after the name of the city in the Irish language.

The theme should compile if you use pdflatex. However, full implementation requires you to use xelatex. This is because the official University branding is very clear that the font of preference is Spectral. This is a lovely font, freely available from Google Fonts, and you can even download it HERE, but pdflatex won’t let you use your own fonts. So if you want to use be very consistent with the branding and use Spectral, you will need to compile your document with xelatex.

An example PDF of the Gaillimh theme is viewable HERE. I include a couple of screenshots below.

You can download all the files you need to install and use the theme in one zip-file HERE.

University College Dublin has an excellent, professionally-crafted visual identity. Credit where it’s due, the branding is distinctive and coherent.

But there isn’t a beamer theme. UCD Marketing have Powerpoints to beat the band, but I (and at least a dozen other people worldwide) prefer generating slidedecks in TeX.

So I have made a beamer theme to replicate the official UCD branding. There is a norm of naming beamer themes after university locations such as AnnArbor or Berkeley. The UCD beamer theme is thus named Belfield. Though the UCD brand is very well known on our island, this little bit of research infrastructure can help you represent the university internationally.

An example PDF of the Belfield theme is viewable HERE. I include a couple of screenshots below.

You can download all the files you need to install and use the theme in one zip-file HERE.

Alternatively you can download them individually. Instructions are available from the README.txt. Don’t skip the readme file, it helps with the installation.

On any given day, I will usually be working on only one of several projects in Stata. These projects will often take several years. It should be easy to switch to the folders for these files. For example, to switch to my project on Stamp Duty the command go stamp would be handy.

I wrote a small bit of code to make that happen. You can download go.ado here. Download it, edit it with your own shortcuts, save it to your preferred ado folder, and make it easier to jump to different projects.

When exporting graphics from Stata or Matlab, it’s better to select a lossless/vectorized format instead of a rasterized pic. This ensures your image is high-quality and not grainy/pixelated.

Grainy exports

Poor quality, grainy image

Better quality export

Unfortunately, Matlab does not allow lossless PDF exports of pictures with non-standard fonts. (I’m not the first person to notice this problem. I failed to implement Juan Guerrero’s suggested solution.) Matlab will export the font in PNG no problem, but your image will appear grainy. If you try to export as a PDF, your fonts will be reverted to something weird. Obviously this doesn’t matter if you’re happy with the default fonts, but this bug does limit your ability to customize the output.

Thankfully, with the help of the nice people at Inkscape (https://inkscape.org/) there is a workaround.

  1. Install Inkscape
  2. Generate your figure in Matlab
  3. In “Export Setup”, change the Font to anything saved on your system. Export as Scalable Vector Graphic (SVG) file
  4. Open the SVG in Inkscape
  5. Save it a lossless PDF as, say, figure7.pdf
  6. Include in your LaTeX document with \includegraphics{figure7}

Done!

Over on Twitter, Gray Kimbrough suggests using colour to indicate statistical significance/p-values instead of the traditional stars. This was part of a broader argument for Powerpoint over Beamer.

I much prefer Beamer to Powerpoint, and I knew it would be very easy to implement coloured cells in regression tables directly from Stata into LaTeX/beamer.

I use the wonderful estout to produce regression tables (and have modified it in the past) so here’s how to produce the table above with one extra line in your do-file.

clear
sysuse auto

** This line generates a local named siggreen, defining significance with green opacity
local siggreen "star(\cellcolor{green!10} 0.10 \cellcolor{green!35} 0.05 \cellcolor{green!95} 0.01) nonotes"

** Run a few sample regressions
qui eststo: reg price foreign mpg weight
qui eststo: reg price foreign mpg weight turn
qui eststo: reg price foreign mpg weight turn gear_ratio displacement headroom

** Using esttab, produce the output with Enda's preferred options
esttab using myoutput.tex, replace booktabs nodepvars nomtitle se label ar2 `siggreen' title("Green Regression")

Then, to include that table into your TeX document:

\documentclass{article}
\usepackage[table]{xcolor}
\usepackage{booktabs}
\begin{document}
\input{myoutput}
\end{document} 

If you want to include this tables in your Beamer slides, see this post.

I’ve discussed in the past how to indicate statistical significance with colour rather than stars. Another concern people have about using Beamer is that it can be hard to squish results into one slide. In my opinion, that is solved very easily with my tinytable command.

\documentclass[xcolor={table}]{beamer}
\usepackage{booktabs}

\newcommand{\tinytable}[1]{\textcolor{black}{\tiny \input{#1} }}

\begin{document}
\begin{frame}
\frametitle{Fascinating}
\input{myoutput}
\end{frame}

\begin{frame}
\frametitle{Still fascinating, but smaller}
\tinytable{myoutput}
\end{frame}
\end{document} 

This generates the following:

The economic package includes old commands that are now deprecated within LaTeX. This caused me a problem using the AER bibliography style (aer.bst), and likely causes problems with other BibTeX styles too. My particular problem was with scrartcl refusing to recognise the \bf command rather than the newer \textbf version.

Very specifically, the problem was “Class scrartcl Error: undefined old font command `\bf’.”

The fix for this is simple. Just include the following two lines in the preamble of your document.

\DeclareOldFontCommand{\bf}{\normalfontbfseries}{\textbf}
\DeclareOldFontCommand{\it}{\normalfont\itshape}{\textit}

You could alternatively open up your *.bst file and manually change the code, but the two lines above should fix it.

There has been much hand-wringing about Apple’s low effective tax rates, particularly since the European Commission’s declaration that they know more about the correct implementation of Ireland’s tax laws than Ireland’s own tax authorities. This has focused the public eye on the taxation of multinational corporations in Ireland and elsewhere. There is a problem with the taxation of MNCs, but I argue it is a problem largely attributable to actions in Washington DC, not anywhere else.


Let me explain. The US headline corporate tax rate is 35%. Thus if an American company earns $100 in the United States, the IRS expects that company to pay a total of $35 in taxes. Further, the US corporate tax base is structured on a worldwide income system. So if Starbucks earns $100 in Denmark, the IRS still expects the company to pay a total of $35 in taxes. For example, if Starbucks pays $20 in taxes to Denmark, the residual $15 is due in taxes to the US. (See here for an example of this offsetting rule.)

Continuing with the Denmark example, the amount due to the Danish government must by law account for the fact that a lot of Starbucks’ profitability comes from its intellectual property: its recipes, branding, and so on. That intellectual property is American, not Danish. For the sake of argument, let’s say that 75% of Starbucks’ profitability in Denmark is based on American intellectual property, and the rest is due to shrewd decisions by managers in Copenhagen. (Change these numbers as you see fit, the idea still holds.) Thus although Starbucks will technically book $100 of profit in Denmark, 75% of that is “American profit”, with only 25% attributable to decisions by the Danish operation. Denmark’s corporate tax rate is 22%, so Starbucks will owe 22% of $25 = $5.50 to Denmark. But recall that they booked $100 of gross profits in Denmark so, on the face of it, The Guardian and other such outlets will wail that Starbucks gets away with a tax rate of only 5.5%. How unfair, how unjust, etc.

Of course what The Guardian and The Huffington Post will typically fail to mention is that the IRS expects the residual $29.50 to be paid in the US ($35 less the $5.50 paid in Denmark = $29.50). That is the main reason why newspaper headlines mislead the public. But a further, more substantive issue that is rarely discussed in the media is where the real problem comes in: the United States’ unusual treatment of (unrepatriated) foreign profits.

What is this unusual treatment? Starbucks do not have to pay that tax liability until they redistribute the profits back to the shareholders by way of a dividend payment. So it is perfectly legal, as per the Tax Reform Act of 1986, for Starbucks’ profits to sit in a bank earning interest rather than paying up to the IRS.

Regular US taxpayers have to pay their previous year’s taxes by April 15th. Corporations can choose when they pay up, and they are welcome under US tax law to wait many years to do so. They may even hold out in the hope that Congress drops the tax rate — for example Donald Trump has proposed lowering the corporate tax rate from 35% to 15% — and end up paying much less than previously thought. Apple is sitting on about $150bn dollars of unrepatriated profits. They’re holding out (completely sensibly, from their perspective) for a law change so when it comes to paying up, they do so at a lower rate. This holding out again makes it appear that companies like Apple’s tax liabilities are lower than they actually are. How unfair, how unjust, etc. Yet I don’t think I have ever seen a newspaper discuss the intricacies of why an existing US law — the Tax Reform Act of 1986 — encourages this perverse behaviour, nor do I predict a flurry of articles heaping praise on Apple or Starbucks when their effective tax rate shoots through the roof when they eventually repatriate back-dated income.

You can also perhaps see why Apple’s low tax payments in Ireland are an issue for Washington, not Dublin.

Finally, all this is relatively moot if we fail to consider the incidence of corporate taxes. Most members of the public understand that taxes on oil are passed onto the consumer, at least in part. However, the same logic has yet to penetrate the public consciousness on corporate taxes. If you tax a corporation, the workers and customers of that corporation cannot magically wave a moral wand and avoid the economic repercussions of the tax. Some of that tax will inevitably be passed onto consumers, some onto workers, some onto shareholders, etc.

Exactly how the tax is split between groups is a tricky thing to statistically disentangle. However, recent research suggests that about 30% of corporate taxes in the US are passed onto the corporation’s employees; and excellent work by German economists suggests that over there perhaps as much as 80% is passed onto workers. The clamour for increased taxation of multinationals almost never considers this reality. I have never seen it mentioned in newspapers that if large multinationals are successfully dodging taxes, it is almost certain that their consumers and workers also benefit from this.

To be clear: I like The Guardian; the Tax Reform Act was a considerable improvement overall; and corporations should pay the tax rates that are demanded of them by law. However the depiction of corporate taxation in the media routinely overlooks mandatory deductions for intellectual property, the deferral of unrepatriated foreign earnings, and the crucial issue of incidence/who actually pays the corporate tax.

Debate on the topic suffers as a result.

“The decisive inhibitions, then, will always be those on the actual use of nuclear weapons. By far the worst consequences of their possession would be the use of them. Possession itself can be mischievous; and the stronger the perceived limitations on the usefulness of nuclear weapons, the stronger will be the considerations militating against acquisition.

There is a stronger way to phrase this. A government that would use nuclear weapons if it had them, and could get them, would get them. No inhibition on mere possession could survive a decision to use them. […]

In these conditions—and we are probably talking about the 1990s—possessing or not possessing some nuclear weapons, or having it known or not known that a country possesses some nuclear weapons, will not decisively differentiate countries as it may have done in the past. The difference will seem greatest when it doesn’t matter much. […]

The organizations most likely to engage in nuclear terrorism will be national governments. Passive terrorism on a grand scale we call “deterrence.” When it is directed at us, rather than at our enemies, we call it “blackmail.” […]

Some of the more dramatic acts of terrorism that we have read about in recent years have been initiated by individuals or small groups that had more passion than perseverance, more interest in getting attention than in getting results. They did not appear to be well-articulated pieces of a grand strategy in furtherance of a major objective. Most of them do not seem to have involved careful planning by large numbers of thoughtful people. But an organization that had the brains and the money and the teamwork and the discipline to bring off the successful construction of a nuclear bomb would have plenty of time and plenty of reason to think carefully about how to use this potential influence, this dreadful threat that may be as diplomatically unwieldy as it is enormous.”

— Thomas Schelling (1984), “Who Will Have the Bomb?” in Choice and Consequence.
