State of the tech job market halfway through 2025? Still stagnant, still not much better than the last 2.5 yrs.
Tech employment has dropped modestly from its Dec 2022 peak, falling 1.9%, or 76,000 jobs, with no improvement in 2025, despite the hype around AI + data center investment.

What is behind tax elasticities? Often we think firms move when taxes increase. Asked directly, they indeed complain but experimental evidence shows they will not act. Instead tax cuts attract investments. Tax policy works like a ratchet due to home bias: dx.doi.org/10.2139/ssrn...
