What is the Men's Underwear Index?

Men defer boring purchases when worried about money. When underwear sales dip, consumer confidence has already cracked — Alan Greenspan cited this as a leading indicator of economic sentiment.

What is the Cardboard Box Index?

Every shipment needs a box. Cardboard box production is a surprisingly clean leading indicator for real economic activity, often moving a quarter before GDP catches up.

What is the Big Mac Index?

The Economist invented the Big Mac Index in 1986 as a lighthearted measure of purchasing power parity. Same burger, same process everywhere — the price tells you exactly how far your dollar goes relative to other currencies.

What is the Temp Staffing Index?

Employers hire temporary workers before committing to permanent staff — and cut them first when conditions worsen. The Temp Staffing Index consistently leads total payroll employment by 2–3 months, making it one of the cleanest early warning signals in the labor market.

What is the Lipstick Index?

Estée Lauder's Leonard Lauder noticed lipstick sales jumped as the 2001 recession hit. The theory: when consumers cut big luxuries, they substitute small affordable ones. Lipstick sales rising in a downturn has held up across multiple recessions as a reliable consumer sentiment signal.

What is the Used Car Price Index?

Used car prices are hyper-sensitive to credit conditions and supply chain shocks. In 2021, used vehicle prices alone were responsible for roughly a third of U.S. CPI inflation — a single line item moving the headline number economists use to set monetary policy.

What are leading economic indicators?

Leading economic indicators are data points that tend to change before the broader economy shifts. Unlike GDP — which is reported months after the fact and revised repeatedly — leading indicators like temp staffing, cardboard box shipments, and credit card delinquency rates give an early read on where the economy is heading.

Why are alternative economic indicators more accurate than GDP?

Official GDP figures are released with a significant lag, revised multiple times, and subject to methodological smoothing. Alternative indicators like temp staffing employment, cardboard box shipments, and Big Mac prices update faster, are harder to manipulate, and reflect what real people are actually doing with their money.

Are we in a recession right now?

GDPv2's real-time recession probability score aggregates leading alternative indicators — temp staffing, credit card delinquency, cardboard box shipments, and consumer sentiment — into a 0–100 score updated daily. Official GDP lags by months. Alternative indicators lead by quarters. The dashboard shows the current score and the signals driving it.

What is recession probability and how is it measured?

Recession probability is an estimate of the likelihood that the U.S. economy is in or entering a recession, based on leading indicators. GDPv2 calculates it by weighting temp staffing trends, credit card delinquency rates, cardboard box production, and S&P 500 direction — all of which historically lead official recession declarations by one to three quarters.

Are we in a recession right now?

GDPv2's real-time recession probability score provides a current read based on leading alternative indicators — temp staffing, credit card delinquency, cardboard box shipments, and the Men's Underwear Index. Official NBER recession declarations lag by 6–18 months. GDPv2's score updates daily using data that historically leads those declarations by one to three quarters.

What is the GDPv2 recession probability score?

The GDPv2 recession probability score is a 0–100 composite index that blends traditional indicators (unemployment, S&P 500, temp staffing, consumer sentiment, credit card delinquency) with alternative leading indicators (cardboard box shipments, Big Mac Index, Men's Underwear Index). Scores above 60 indicate elevated recession risk. The score updates daily and is designed to signal stress before official GDP figures confirm it.

Why Cardboard?

Nearly every physical good shipped in the U.S. — from Amazon packages to auto parts to grocery store inventory — requires a corrugated box. Box demand is upstream of everything. When businesses order fewer, they're planning to ship less. That decision shows up in box production data before it shows up anywhere in official GDP.

The Lead Time

Supply chains commit to packaging before goods are produced. A manufacturer cutting box orders 20% this month isn't shipping 20% less yet — but they're planning to. That forward-looking quality gives the series a consistent one-to-two quarter lead on industrial production and GDP growth. Most economists ignore the PPI sub-index. That's why it still works.

2022–2023: When the Signal Got Loud

The post-pandemic inventory glut is the cleanest recent example. Box demand cratered in 2022 as retailers worked through excess stock — months before the official goods recession showed up in headline GDP. The cardboard market knew first.
