From Natalia Emanuel, Valentin Bolotnyy, and Pim Welle: The involuntary hospitalization of people experiencing a mental health crisis is a widespread practice, as common in the US as incarceration in state and federal prisons and 2.4 times as common as death from cancer. The intent of involuntary hospitalization is to prevent individuals from harming themselves…

These people are saying it is there too. Though I am not quite sure what they (or anyone, for that matter) mean by AI: First, we argue that AI can already be seen in productivity statistics for the United States. The production and use effects of software and software R&D (alone) contributed (a) 50 percent…

Congressional leadership is corrupt

Using transaction-level data on US congressional stock trades, we find that lawmakers who later ascend to leadership positions perform similarly to matched peers beforehand but outperform them by 47 percentage points annually after ascension. Leaders’ superior performance arises through two mechanisms. The political influence channel is reflected in higher returns when their party controls the…

In a post last week I included this chart of the latest annual OECD data on labour productivity, expressed in PPP terms. It was grim, in a familiar sort of way. New Zealand’s overall economic performance has long been poor (the halcyon days when New Zealand was in the top 3 in the world relegated […]

From a forthcoming paper by Thomas Drechsel: This paper combines new data and a narrative approach to identify variation in political pressure on the Federal Reserve. From archival records, I build a data set of personal interactions between U.S. Presidents and Fed officials between 1933 and 2016. Since personal interactions do not necessarily reflect political…

Andrew Leigh on big data vs. randomised controlled trials
20 Nov 2025 Leave a comment
in econometerics, history of economic thought
‘Big data’ has become the catchcry of many data scientists and researchers in recent years. It’s also become increasingly used in economics. However, by itself the analysis of big data doesn’t provide anything but big data correlations. Even when big datasets are available, there is still a place for randomised controlled trials (RCTs). That is…

50 years of economic progress – but are New Zealand households better off?

Wayne Jackson writes – The 50th anniversary of New Zealand’s Household Economic Survey (HES) provides a unique vantage point to assess how far households have come in terms of income, expenditure, and wealth accumulation. Comparing 1974 with 2024 reveals a story of rising prosperity, shifting household structures, and widening disparities. From dual‑income households to skyrocketing […]

A new critique of RCTs
02 Nov 2025 Leave a comment
in econometerics, history of economic thought
Randomized Controlled Trials (RCTs) are the gold standard for evaluating the effects of interventions because they rely on simple assumptions. Their validity also depends on an implicit assumption: that the research process itself—including how participants are assigned—does not affect outcomes. In this paper, I challenge this assumption by showing that outcomes can depend on the […]

In a great paper, The Impact of Jury Race in Criminal Trials, Shamena Anwar, Patrick Bayer and Randi Hjalmarsson exploit random variation in the jury pool to estimate the effect of race on criminal trials. The authors have data from nearly 800 trials in two Florida counties. On any given day, a jury pool is randomly […]

In my ECONS102 class, we cover economic explanations for media bias. Drawing on past research from Matthew Gentzkow and others, we demonstrate that there are demand-side explanations (media bias arises because of a bias in the preferences of the news-consuming public) and supply-side explanations (media bias arises because media firms segment the market, and focus…

From 1990 to 2010, rising numbers of H-1B holders caused 30–50 percent of all productivity growth in the US economy. This means that the jobs and wages of most Americans depend in some measure on these workers. The specialized workers who enter on this visa fuel high-tech, high-growth sectors of the 21st century economy with skills like computer […]

Effective tax rates increase from 2% for the bottom quintile of income to 45% for the top hundredth of one percent. But rates may be lower among those with the highest wealth.

I’ve written several articles about the failure of Cuban socialism (2024, 2022, 2021, 2019, and 2016). My leftist friends almost always respond by claiming that U.S.-imposed trade restrictions are the primary reason for Cuba’s terrible economy. Since I like free trade, I certainly agree that trade restrictions are bad for growth (a lesson I wish […]
