Every exhibit.
Each table and chart from the journal, in one place. Every one downloads as a PNG from the essay it belongs to — with its title, its source line and its attribution already in the image.
Files are named to a fixed pattern so they stay identifiable years from now: author, year, essay, number. If you have a downloaded file and want to find where it came from, search for its filename.

Every published depreciation rate, and what it was measured on
From Every growth budget is a gross number

The same asset, left alone, at three published rates
From Every growth budget is a gross number
Source Curves computed as (1 − d) raised to the power t, from the published rates in Table 1: 2.5% a year (Bronnenberg, Dubé & Gentzkow 2012), 20% (the assumed organisational-capital rate, Ewens, Peters & Wang 2024), 55% (Corrado et al. 2016 via Bronnenberg, Dubé & Syverson 2022). A disclosed model, not measured data.

From Every growth budget is a gross number
Source Simulation, 20,000 runs per design. An AR(1) quarterly series, persistence 0.3, standard deviation 15% of level, with a true depreciation rate of exactly zero; twelve quarters before the stop and eight after. Script: instrument-test-decay.py, filed with the claim ledger.

How much of a change in spending has reached the asset
From Every growth budget is a gross number
Source Author’s calculation from the capital accumulation identity: the share of a permanent change in the maintaining flow that has arrived in the stock after t years is 1 − (1 − d) raised to the power t, where d is the annual rate. Rates as in Table 1.

Almost nobody goes looking for a price
Monthly search volume for the category term itself, against the searches that explicitly ask what it costs.
From Pricing is a positioning decision.
Source Author's analysis of DataForSEO Google Ads search volume, 12-month average to June 2026, pulled 25 July 2026. Google Ads reports volume in rounded bands, so ratios are approximate; near-duplicate keywords are counted once.

How much of the deliberate searching is about price
Of the searches in each cell that are either price-shaped or comparison-shaped, the share that is price-shaped. The highest is one in six; four of the six are under six per cent. The German volumes sit inside Google’s coarsest rounding band and should be read as small rather than as exact.
From Pricing is a positioning decision.
Source Author’s analysis of DataForSEO Google Ads search volume, 12-month average to June 2026, pulled 25 July 2026. The denominator is a price- and comparison-shaped term set fixed before the pull and listed in the dataset note — not all searching in the category. Rows in the order the set was specified. The German and English modifier sets are not exact translations, and the German volumes fall in Google’s coarsest reported band.
