Their work has fed into top decision-making processes, appearing in House of Representatives economics committee inquiries, meetings and submissions.
But funded by the Susan McKinnon Foundation, the Macquarie Business School and the Becker Friedman Institute, e61’s work is also freely available to the public. And the things you can learn from them are fascinating – providing insight into how economics applies in the real world – beyond the abstract, and beyond the bookish or theoretical.
Matthew Elias, for example, looked at the role we – as consumers – play in the highly concentrated supermarket sector.

As you know, Coles and Woolworths control about 67 per cent of supermarket retail sales nationally, and they’ve been under the scrutiny of the competition watchdog which is due to release its final supermarket inquiry report this year. While the supermarkets have copped some heat from frustrated consumers convinced that the lack of competition in the sector has led to excessive price growth, Elias found part of the problem was that customers don’t tend to shop around.
Shopping around, and the threat of customers leaving, is an important way to put pressure on businesses to deliver the best prices and quality they can. But looking at consumer shopping data, Elias found even in areas with several providers, shoppers tended to exhibit inertia: that is, they don’t tend to change their shopping habits over time, instead returning to certain supermarket brands – especially Coles and Woolworths.
Why? The answer is unclear, but some possibilities include costs including time spent learning the layout of a different store, the effort needed to compare the costs of various items, proximity to certain stores and brand loyalty promoted by schemes like Flybuys or Everyday Rewards.

Jack Buckley, Ewan Rankin and Dan Andrews meanwhile looked at non-compete clauses: where an employee agrees not to compete with their employer by, for instance, working in a similar industry, for some time even after their job ends.
About one in five of us are tied up in a non-compete clause, and it’s coming at a cost – not just to our economy (people switching to better-suited jobs can help improve innovation and lift productivity), but also to our pay.
The researchers found evidence that the fall in job mobility (people moving between jobs) was linked to lower wage growth for workers with non-compete clauses. On average, they found, people with non-compete clauses earn 4 per cent less than similar workers with just a non-disclosure agreement (aimed just at preventing employees from sharing trade secrets).

Then there’s research by Rachel Lee, Dan Andrews and Jack Buckley which sounded a warning for policymakers looking to tweak their payroll tax settings. When South Australia bumped up the payroll tax-free threshold (which also sharply increased the marginal tax rate for firms over that limits), it led to a phenomenon called “bunching.”
Basically, e61’s analysis of business income tax data found lots of new businesses in South Australia were ending up just below the new payroll tax threshold. Since firms with an annual wage bill of less than $1.5 million could be exempt from payroll tax, there was a jump in the number of firms just under that size – despite a lot of those businesses being productive and growing firms which you’d expect to continue growing.
The conclusion? That little tweak in the payroll tax settings may have stunted the growth of many businesses, which cut back on their workers in an effort to slash their payroll tax. Sure, it benefited some smaller firms which were able to grow within that threshold, but the costs of businesses shrinking their payrolls was bigger.
Kaplan says he wants to see e61 be at the forefront of major policy movements over the next debate: both avoiding bad policy mistakes and guiding good policy. It might take a while for the new kid on the economics block to become a hard-hitter, but linking some of the brightest academic economists with crucial policy problems is helping to inject rigour into our understanding of economics – and that of our policymakers.
