Cleaning Hansard: The pay's not great but the work is hard

A short description of the post.

The SQL Is Never As Good As The Original

SQL is a popular way of working with data. Advanced users probably do a lot with it alone, but even just having a working knowledge of SQL has increased the number of datasets that I can get data from to then analyse with other tools such as R or Python. You can use SQL within RStudio if you want. The following are a few notes to help future-Rohan when he needs to use SQL. A worked example with a sample of the Hansard data will be included in a future post.

Topic Modelling - Theory

Each statement in Hansard needs to be classified by its topic. Sometimes Hansard includes titles that make the topic clear. But not every statement has a title and the titles do not always define topics in a well-defined and consistent way. One way to get consistent estimates of the topics of each statement in Hansard is to use the latent Dirichlet allocation (LDA) method of Blei, Ng, Jordan, @Blei2003latent, as implemented by the R package 'topicmodels' by Grun @Grun2011.

Getting started with LaTeX

LaTeX makes it easier to produce papers that look great, but it can be overwhelming at the start. These notes help you get up-and-running with LaTeX.

Reproducing a Grattan Institute map

Blogdown is a package that allows you to make websites (not just blogs, notwithstanding its name) largely within R Studio. It builds on Hugo, which is a popular tool for making websites.

Mapping the 2016 Australian Election Polling Place Results

The note that follows introduces Australia's political system, and then details the process of downloading and merging first-preference votes by polling place, and then plotting it on an interactive map.

Greitens Reports For Duty

Eric Greitens may be the Republican Übermensch. Rhodes Scholar, Navy SEAL officer, husband and father. He's now the Republican candidate in the Missouri gubernatorial election. And one suspects that being a governor could just be a step for Greitens. While 2016 will always be the year that US politics descended to the gutter, it could also be the year that the next Republican president begins his political career.

Professional Amateurs

Despite many unforced errors Hillary Clinton has won the Democratic nomination and polls suggest she will beat Donald Trump. But her campaign continues to make unforced errors. There was plenty of evidence of an amateur nature to what should be a professional campaign at a recent rally for Clinton’s running mate, Tim Kaine, in Grand Rapids, Michigan.

Trump, Revisited

Donald Trump is an improved politician, but it's unlikely to be enough. He has harnessed fervent anti-Clinton sentiment amongst Republicans. But he does not have time to build the coalitions usually needed to win a US presidential election.

Broader Thinking Needed on the Australian Budget

The Treasury Secretary, and many others, bemoan the wasted years of the mining boom. Most agree that Australia should have more to show for what was the most significant boom since Federation. But the boom is over. And a fixation on budget surpluses means that we are missing an opportunity to make up for it. Australia’s credit rating is a strength that we should take advantage of. The Commonwealth should be borrowing to fund infrastructure investment.

Notes and Photos From Iowa

Bernie Sanders seems quite reasonable for a revolutionary. An energetic man of 74, he spoke for an hour in Perry, Iowa, to a room of 300 from only a few lines of handwritten notes, and then fielded half an hour of questions. He does not have the same aura that surrounded, then, Senator Obama in his own Iowa battle with, then, Senator Clinton in 2008 say those who saw both. Instead, Sanders has preternatural calm.

Prepare For Future Economic Crises Now

Few policymakers were prepared for the financial crisis of 2007-08. Until it hit, their focus was on more obvious threats to the economy, instead of such an unexpected event. Could this be because planning for unexpected economic events is not the explicit responsibility of any particular policy-maker? If so, this has to change.

In Appreciation of Ronald Coase

Ronald Coase, one of the most influential economists of the twentieth century, passed away in 2013 aged 102. Reading his papers today, I wonder whether he'd have become an economist if he were making that decision now.

I'll Have What They're Having

Some accuse the Rich White Males from San Francisco's Bay Area of only making products for other Rich White Males. But that neglects the fact that what they want is sometimes also what the rest of us want.

The Human Equation: An Interview With George Zachary

In an age when you can buy data-driven refrigerators and Moneyball is nominated for Academy Awards you may be surprised to hear there are investors who describe themselves as gut-driven. Frankly I thought such people would be too embarrassed to be out in public. Then I heard George Zachary talk.

Final Shot At Ending Industrial Disputes

The industrial relations disputes that culminated in the shutdown of Qantas last year took more than nine months to make it through arbitration. Such lengthy delays have left many wondering if changes should be made to the processes that underpin this form of dispute resolution. The use of ‘final offer’ arbitration could be the small change that has a big effect, saving conflicted parties time, money and reputation.

Tournaments Could Drive R&D Effort

The government should use tournaments to stimulate research and development in Australia. They have been largely overlooked since the Cutler Review of Innovation, but when structured properly, they encourage out-standing achievement and promote creative destruction.

Plastic Policies

There is broad agreement that Australian plastic bag consumption should be reduced. To this end, recent South Australian legislation has banned certain types of plastic bags. But other states wishing to reduce their plastic bag consumption may find a tax rather than a ban the more appropriate policy instrument.

Home Buyers Will Be Hurt by Aid Plan

The Government's First Home Saver Accounts policy, announced during the last federal election, is a promise that should never have been made. It will place upward pressure upon inflation and increase the potential for domestic financial turbulence. It will be the individuals that the policy is designed to help (young Australians with a still-insecure financial foundation) that will be most hurt in the long-run.
