The public platform includes dashboards on AI exposure in the labor market, macroeconomic signals, and generative AI use by workers and firms. Stanford Digital Economy Lab has launched AI Economic Indicators, a public platform tracking how AI is affecting jobs, productivity, adoption, and the wider economy The Stanford Digital Economy Lab has launched AI Economic Indicators, a public platform tra…

Ask a freelancer about cash-flow problems and they'll tell you about late-paying clients. Real problem. But there's a quieter, more expensive one almost nobody tracks: the work you finished and never invoiced. The extra revision you did on Friday. The "quick favor" that took two hours. The milestone you completed but forgot to bill because you were already deep in the next project. None of it is …

Your Telegram bot is live. Users are sending Stars. You check your creator dashboard and see 847 Stars sitting there. The question that follows is always the same: what does that actually mean in real money? The answer is more complicated than Telegram's UI suggests — and if you're building a bot or mini app that monetizes with Stars, you need to understand the gap before you publish your pricing…

Exclusive: devolving tax is part of plans to give local areas more power in areas including justice, health and education Ministers are considering handing over billions of pounds raised by business rates to regional mayors as part of one of the biggest shake-ups of the English tax system in recent years. Steve Reed, the local government secretary, said the government was working on plans to devo…

A year ago it was the hot topic, but business owners have seen there’s a limit to the president’s royal decrees In two weeks, I’m speaking to a group of companies in the packaging industry about issues affecting their businesses this year. I’m going to discuss the economy, navigating higher costs, leveraging new tax legislation, AI and what companies are doing to find and retain workers in a vola…

I built a free paycheck calculator because the existing ones annoyed me. Half of them are buried under ad units, and the other half want your email before they will show you a single number. All I wanted was "I make X in this state, what actually lands in my bank account." So I built my own, and then I made the mistake of trying to support all 50 states. Here is what that actually involved. The l…

President Donald Trump says a secret mission moved 100 million barrels of oil through the blocked Strait of Hormuz. That number is impossible to verify.

Tonopah has boomed and mostly busted since it's heyday more than a century ago. Trump has raised expectations for renewed prosperity and one local businessman is sprucing up his motel in anticipation of better times.

As income inequality is reaching serf-lord levels, hating the rich seems easy and reasonable. But maybe we should make sure our outrage is working for us, not against us.

There is an inconvenient truth the artificial intelligence industry prefers to whisper rather than proclaim: the real cost of putting an LLM into production almost never matches the API invoice . It's like buying a car and discovering that the dealership price didn't include the wheels, the insurance, or the fuel. The label says "$0.15 per million input tokens." What it doesn't say is how many mi…

Forecasters were wrong about an immediate recession but right that we would be worse off outside the EU As the 10th anniversary of the Brexit vote approaches, the verdict on Britain’s economic performance is clear: voting to leave has resulted in severe costs for households and businesses. The immediate recession predicted in the Treasury forecasts ordered by George Osborne – dubbed “ project fea…

This article studies estimation and inference in the autoregressive (AR) models with unspecified and heavy-tailed heteroskedastic noises. A piece-wise locally stationary structure of the noise is constructed to capture various forms of heterogeneity, without imposing any restrictions on the tail index. The new nonstationary AR model allows for not only time-varying conditional features but also u…

This article considers a general class of varying coefficient models defined by a set of moment equalities and/or inequalities, where unknown functional parameters are not necessarily point-identified. We propose an inferential procedure for a subvector of the varying parameters and establish the asymptotic validity of the resulting confidence sets uniformly over a broad family of data-generating…

We study minimax regret treatment rules under matched treatment assignment in a setup where a policymaker, informed by a sample of size N , needs to decide between T different treatments for a . Randomized rules are allowed for. We show that the generalization of the minimax regret rule derived in Schlag (2006, ELEVEN—Tests needed for a recommendation , EUI working paper) and Stoye (2009, Journal…

This article extends the validity of the conditional likelihood ratio (CLR) test developed by Moreira (2003, Econometrica 71(4), 1027-–1048) to instrumental variable regression models with unknown homoskedastic error variance and many weak instruments. We argue that the conventional CLR test with estimated error variance loses exact similarity and is asymptotically invalid in this setting. We pro…

How it Works Quadratic funding democratizes allocation by rewarding projects that have broad community support. Collective Intelligence drives match funds For example, four projects raise $400 each. QF allocates funding based on the quantity of donors, not the total amount of money. Cooperative transparency Cooperative transparency Every donation is verified. Public chains (Bitcoin, Ethereum) con…

Token economics is not only about token price. It is about designing the rules, incentives, and long-term logic of a Web3 ecosystem. When people start building a Web3 project, they usually focus on the visible parts first. They think about the smart contract, the frontend, the wallet connection, the token launch, the whitepaper, and maybe the community. All of those are important. But there is on…
