There are many arguments put forward for why trade should be restricted. In my ECONS102 class last week, as part of our topic on international trade and globalisation we covered five of the most common, each of which has a little story that goes along with it:The jobs argument: Trade with other countries will lower…

In my ECONS101 class, we have a topic that is devoted to understanding pricing and business strategies that deviate from the ideal ‘marginal revenue equal to marginal cost’ approach to pricing for firms with market power. In particular, I focus part of the topic on firms that price below the short-run profit-maximising price for strategic…

Who values democracy?

This paper examines the conventional view that redistribution is central to the democratization process using data from stock markets. Consistent with this view, democratizations have a large, negative impact on asset valuations driven by a rise in redistribution risk. Across 90 countries over 200 years, risk premia are substantially elevated— similar in magnitude to financial…

I have a four-part series (here, here, here, and here) documenting that Americans are getting richer over time, yet many people feel pessimism and dissatisfaction. This Kite & Key video helps to explain this seeming contradiction. If you don’t want to watch a 10-minute video, here are two charts that summarize the message. This first […]

The gender wage gap is fading away

The gender wage gap has dropped by two-thirds in the last 30 years. It has halved since the first pay equity claim was filed 14 years ago. The gender wage gap is now barely 5.5% in June 2026 according to the recently released Statistics New Zealand data. It is a stretch to file pay equity claims asking for 30% more when the gender wage gap struggles to stay above 5%.
The gender wage gap data released by Statistics New Zealand recently is the raw data. There are no adjustments to that pay gap for differences in educational backgrounds, continuity of employment and dedication to demanding careers, unsocial hours, risk of injury, and the greater desire of women for work-life balance and jobs with more working from home options.
It is not mischievous to say that the gender wage gap may round down to zero once these factors are considered.
From time-to-time, detailed datasets become available on male and female workers that show that the gender wage gap goes down or close to zero. There are even detailed datasets where hiring and job assignments are made without any management intervention or possible bias.
There is a large gender wage gap driven by work-life balance under a bus and train drivers’ collective agreement in Massachusetts. The work-force was one-third female with hiring via a lottery among applicants with a clean record. Shifts are chosen by drivers strictly according to their seniority at each depot.
There was still a 11% gender wage gap because women drivers elected to work less overtime, they avoided overtime shifts on short notice, and they worked fewer shifts at nights and weekends. This gender wage gap among bus and train drivers cannot be the fault of their sexist employer because work was allocated by an exceptionally detailed union contract.
A 7% gender wage gap emerged even when a computer algorithm is allocating the work first come, first served.
A study of Uber drivers found a gender pay gap of zero once account is taken for male Uber drivers driving more at nights, weekends and in the more dodgy neighbourhoods with drinking establishments. Male Uber drivers also worked more hours per year which meant they had much more work experience than female Uber drivers. These additional hours meant men became more skilled in deciding when and where to best cruise for the best paying jobs. The fact that men drive faster explained the last two percentage points of the gender pay gap at Uber. Speed meant men were available for the next Uber job quicker.
The gender wage gap is just into the double digits for the top 10% of female earners in New Zealand in 2025 (see OECD graphic). This is because their chosen careers are often not family friendly. But even at the top end of town the gender pay gap has halved in the last 20 years.

OECD data explorer
Women’s willingness to trade work-life balance for lower wages and fewer promotions is a big driver of the gender wage gap and the channelling of women into family friendly occupations. The wages of men and women at all levels are similar in the years leading up to motherhood then everything changes.
Top American labour economist Claudia Goldin found that some careers severely penalise any time off such as for motherhood or working less than punishingly long or rigid hours. Goldin refers to these jobs as greedy jobs. Women’s preference for family friendly occupations that can pay less and a tendency to avoid greedy jobs will mean that the gender wage gap may always be with us at least at the big end of town.
The Allocative Cost of War

Why is war so economically costly? Our answer is that modern war lowers output not only by destroying productive factors, but also by making the surviving economy work less efficiently. Using uniquely comprehensive firm-level data collected during Russia’s full-scale invasion of Ukraine in 2022, we document a dramatic collapse in allocative productivity in Ukraine. To…

The Pro-Growth Impact of Deregulation
12 Sep 2026 Leave a comment
in applied price theory, economic growth, economic history, economics of regulation, entrepreneurship, macroeconomics Tags: European Union

Regulation adds “clutter” to an economy, sort of akin to creating an obstacle course that workers and businesses have to navigate in order to be productive. In other words, red tape makes it harder to be profitable. And that reduces incentives to invest. And every economic theory agrees that less investment means less prosperity. That’s […]

‘Incomplete Contracts and the Theory of Contract Design,’ by Robert Scott and George Triantis
11 Sep 2026 Leave a comment
in applied price theory, economics of information, economics of regulation, history of economic thought, industrial organisation, law and economics, property rights

Economists and lawyers know that almost every contract is incomplete. Contracts routinely omit or leave undefined important terms, and they rarely anticipate every circumstance that might frustrate performance. The reason is simple: It makes little sense to spend $1,000 drafting a provision that has an expected value of only $100. Parties therefore leave lower-value contingencies…

Bilateral, plurilateral, and multilateral are words that New Zealand’s civil service love. There is nothing that can’t be improved by doing it in concert with others. Sometimes there’s good reason for just doing stuff. New Zealand made the right decision when it unilaterally slashed all of its tariffs. It also progressed all the other trade agreements that helped…
