The Constitution explicitly states that neither the Congress nor any state may pass an “ex post facto Law,” which imposes criminal liability for past actions that weren’t restricted at the time. The Maryland, New York, and Vermont acts all propose to tax companies retroactively for legally producing fossil fuels.

Numerous empirical studies show a relationship between a drug’s expected market size and the magnitude of research and development investments. Early studies focused on changes to market size resulting from the demographics of disease burden (Acemoglu and Linn 2004) and policy changes influencing market demand (Finkelstein 2004). These findings have largely been confirmed by more […]

I’m currently in Finland for meetings with various people and I learned that the country’s bloated public sector and expensive welfare state are imposing a very heavy cost on the economy. How heavy of a cost? According to IMF data, there’s been no growth in per-capita GDP over the past 18 years. Why is Finland […]

Labour leader Chris Hipkins has joined the chorus of those opposing changes to pay equity legislation. Does this mean he knows what a woman is now? It is easy for opposition parties and their allies to criticise proposed changes but Heather du Plessis-Allan points out the problem with existing legislation: . . . Those pay […]

The Hollywood Reporter has a good piece on Trump’s proposed movie tariffs: Even if such a tariff were legal — and there is some debate about whether Trump has the authority to impose such levies — industry experts are baffled as to how, in practice, a “movie tariff” would work. “What exactly does he want […]

TweetHere’s a letter to The Hill. Editor: Pres. Trump said that “China probably will eat those tariffs” (“Trump says China ‘probably will eat those tariffs’,” April 29). So the president believes that the tariffs will be ‘eaten’ by China – meaning, he believes the tariffs won’t result in higher prices in America of Chinese goods.…

The fervent proponents of proportional representation should take heart that the Bloc […]

A couple of months ago now I wrote a post about the new set of discount rates government agencies are supposed to use in undertaking cost-benefit analysis, whether for new spending projects or for regulatory initiatives. The new, radically altered, framework had come into effect from 1 October last year, but with no publicity (except […]

Eric Crampton writes – Come the next pandemic, we are going to be in the same stupid mess that we were in during the last one. Trusted pharmaceutical regulators overseas, like those in Australia, Canada, Europe, and the UK, will have given provisional approvals for vaccines that are safe. And Kiwis will have to wait, […]

My latest paper, Pandemic Preparation Without Romance, has just appeared at Public Choice. Abstract: The COVID-19 pandemic, despite its unprecedented scale, mirrored previous disasters in its predictable missteps in preparedness and response. Rather than blaming individual actors or assuming better leadership would have prevented disaster, I examine how standard political incentives—myopic voters, bureaucratic gridlock, and […]

Associate Health Minister Casey Costello wrote to interim chief executive Dr Dale Bramley on 27 March, telling the agency to use “clear language”. “Recent documents that have reached my office from the […]

From Refineries to Fiefdoms: Is Newsom Orchestrating a State Takeover of California’s Oil Industry?

California’s refining capacity is collapsing—not because demand has disappeared, but because it is being deliberately dismantled by regulatory fiat. The recent announcement that Valero Energy will idle or shutter its Benicia refinery by 2026 isn’t just a business decision. It’s the calculated result of a hostile policy environment designed to punish traditional energy producers until they either leave the state or fall into government hands.
