Template talk:Inflation

GDP deflator for other countries

So what do we do for capital expenses that aren't US/UK? Just can't use the template? It seems like converting cost from back then -> USD -> inflate with US-GDP -> convert back to target currency is going to introduce a lot of inaccuracy. Or does the ballpark figure nature of all these estimates mean the inaccuracy is acceptable as long as you round to thousands/millions/etc.? 47.155.41.201 (talk) 22:20, 27 June 2023 (UTC)

Seems to me (WP:OR is allowed in talk, though I didn't actually do any R) that for some things prices are global. When we hear about the price of oil, that is on the world market, and so such conversions should work. Then there is the Big Mac Index for comparing different countries. But many items are not globally traded, or have other reasons not to keep price parity. Gah4 (talk) 21:42, 13 December 2023 (UTC)

Generate footnote automatically?

Is there a way to do the equivalent of

({{Inflation|index=US|value=x|start_year=y}}{{Inflation/fn|US|group=note}}

without having to explicitly invoke both templates? Something like

({{Inflation|index=US|value=x|start_year=y|group=note}}

would be simpler. Is that possible? RoySmith (talk) 16:13, 29 November 2023 (UTC)

also...

Since I'm here, is there a nicer way to do this:

$1 million (equivalent to ${{format price|{{inflation|US|1000000|1908}}}} in {{Inflation/year|US}}),{{Inflation/fn|US|group=note}}

which is a mouthful. RoySmith (talk) 15:43, 30 November 2023 (UTC)

• RoySmith, I think I've got a similar issue—I want my inflation equivalency to be in a note (|group=note}}) rather than a ref. Have you already achieved that or have I misunderstood the issue you raise here? Happy noo year! ——Serial 20:07, 2 January 2024 (UTC)

  You can pass |group=note to {{Inflation/fn}}. RoySmith already did that above. There's no way of doing what RoySmith listed above in one template call that I can see right now. * Pppery * _{it has begun...} 00:02, 3 January 2024 (UTC)

Feature request: automatic r=

The documentation for this template says inflation is not accurate to better than 1% or so. The output ought to be automatically rounded off to 2 or 3 significant figures if the r= parameter is not provided.

Note there is no value of r= that means "2 significant figures". You have to look at the inflated output and calculate the right r= value. {{Convert}} has more useful controls. Vox Sciurorum (talk) 19:33, 13 December 2023 (UTC)

Default Output of Inflation Template

Moved from help desk

The Inflation Template returns an error if the date is out of range.

Can this be avoided, such that it returns the input value as if inflation was 0 (or another reasonable value)?

edit: This is a problem in this page (in the section for Hulu). It would be easier for editors if it just showed the real value until the data is eventually added (or if it got edited autmatically).

Garvey 96 (talk) 13:33, 7 January 2024 (UTC)

@Garvey 96: Hi there! When having an issue with a template, I suggest posting on the template's talk page first, preferably with an example. Thanks! GoingBatty (talk) 21:58, 7 January 2024 (UTC)

Returning an error seems like the right approach. Returning a value makes it seem like the input, and therefore the output, is valid when it is not. Mathglot (talk) 04:59, 8 January 2024 (UTC)

I think that errors should only be shown to editors and not to viewers of the page. Garvey 96 (talk) 09:34, 10 January 2024 (UTC)

Showing an error message to our readers may be ugly, but showing them erroneous information and pretending it's real is far worse. RoySmith (talk) 15:23, 10 January 2024 (UTC)

This looks like an functional error in the template to me. To take an example:

• {{Inflation|US|8,610,000,000|2021|fmt=c|r=-6}} results in 9,681,000,000
• {{Inflation|US|8,610,000,000|2022|fmt=c|r=-6}} results in 8,964,000,000
• {{Inflation|US|8,610,000,000|2023|fmt=c|r=-6}} results in 8,610,000,000
• {{Inflation|US|8,610,000,000|2024|fmt=c|r=-6}} results in 8,610,000,000

The template should not be producing an error for 2023, and editors shouldn't be expected to work around this. The 2021 and 2022 indeces work, but only inflate to 2022. The 2024 index is the only that would read as correct to the reader, signifying that there has been no inflation between 2024 and 2024. There is no reason to make 2023 return an error value, because the problem will be fixed once the inflation figures are released for 2023. The problem only occurs because there is a bit of a lag in the data. What you are going to get is editors introducing hacks by adding unadjusted figures to lists and tables to avoid getting an error message, meaning that the numbers won't update through the years.

Szmenderowiecki, entirely up to you if you want to do this, but since you're updating Russian inflation statistics and are a Russian speaker, if you have the time it would be quite helpful if you could add the data in this document, which I can't read, to the template if it provides anything useful (it also seems more reliable than the current National Economy of Russia source). Zoozaz1 (talk) 00:32, 3 March 2024 (UTC)

Absolutely, will look into that. Szmenderowiecki (talk) 15:48, 4 March 2024 (UTC)

Zoozaz1 Here I found a downloadable and better searchable version of this paper, but even though the scope of work is admirable, each of the components is assessed separately (so prices on grains, clothing, metals, salt etc.). There is no one CPI measure in this work, and calculating it ourselves will definitely be verboten.

Also, this work only covers the XVI century. There's a lot of economic literature listed here that may be useful for the XVII century but I will have to read it when I have time. Szmenderowiecki (talk) 17:14, 4 March 2024 (UTC)

Update requested for US 2023 data

Template is not yet showing US data adjusted to 2023. See the examples on Template:Inflation/doc that are like {{Inflation|US|...|fmt=eq|...}} which are still rendering as "in 2022" rather than "in 2023". I see that Template:Inflation/US/dataset has been updated with 2023 data, but I think that also Template:Inflation/year still needs to be updated for 2023? Thanks. netjeff (talk) 19:30, 10 March 2024 (UTC)

SWinxy made two edits in responding to this edit request: one to Template:Inflation/US/dataset to add the 2023 figure (per edit req) and one to Template:Inflation/fn to Update US access-date. A comment on Template:Inflation/US/dataset says:

<!-- *** When changing this, also update the reference in Template:Inflation/fn and the latest year in Template:Inflation/year! *** --> – wbm1058 (talk) 14:08, 29 March 2024 (UTC)

Clearly Template:Inflation § Developer documentation leaves something to be desired, as we have issues with drive-by template editors responding to edit requests here.

All pages with titles beginning with Template:Inflation/US shows that there are two US inflation datasets:

• {{Inflation/USD}}, which redirects to {{Inflation/US}}, {{Inflation/US/dataset}}, {{Inflation/US/startyear}}
• {{Inflation/US-CAP}}, which redirects to {{Inflation/US-GDP}}, {{Inflation/US-GDP/dataset}}, {{Inflation/US-GDP/startyear}}

Sdkb edited Template:Inflation/year @ 02:13, 28 March 2024, to Update US cap on behalf of User:SWinxy (note the hidden comment next to the edit here).

But SWinxy edited {{Inflation/US/dataset}}, not {{Inflation/US-GDP/dataset}}. We need to be clear on what the difference is between these, and make sure that we're updating the correct one. – wbm1058 (talk) 15:19, 29 March 2024 (UTC)

Asking for updates in multiple places (especially with something as complicated as this) is always going to cause issues, no matter how strong the hidden comment warning. Could we design it so that e.g. {{Inflation/year}} automatically reads the other templates and derives the most recent year from them? Sdkb ^talk 15:25, 29 March 2024 (UTC)

Aw, shoot. Sorry for messing this up. While I erroneously missed editing Inflation/year, the edit request was to Inflation/US/dataset. Does Inflation/US-GDP/dataset need to be updated as well? SWinxy (talk) 17:52, 29 March 2024 (UTC)

OK, getting myself up to speed. The source for {{Inflation/US/dataset}} is the Federal Reserve Bank of Minneapolis, and right, that's what you got in the previous edit request.

The source for {{Inflation/US-GDP/dataset}} is Samuel Willamson's MeasuringWorth website, per the template documentation. That was last updated by Titan877 at 07:15, 30 November 2023, and I see that Titan877 was responsible for a couple of 30 November 2023 edit requests above, which were done by Paine Ellsworth. Those updated the year from 2021 → 2022, and came from http://www.measuringworth.com/datasets/usgdp/

On that page, you use the form in the grey box on the upper right of the page. Check the box for "US GDP Deflator", enter initial year 1790, ending year 2023, then click Retrieve, and...

Voila, we have a number for the year 2023, 122.27 – so, yes, we can update that from 2022 → 2023 now. Apparently that was done months late, last year, since it wasn't done until the end of November. – wbm1058 (talk) 19:20, 29 March 2024 (UTC)

Suggestion: Use a more up-to-date inflation metric

The United States has two common inflation metrics: the CPI and the PCEPI (Personal Consumption Expenditure PI). The CPI and its variants are designed for cost-of-living adjustments to wages in negotiated contracts. As a result, the CPI excludes many common goods (such as health insurance) provided as fringe benefits rather than being paid for out-of-pocket. The PCEPI gives a more complete picture by including all consumption goods and services. The CPI is also methodologically awkward in that it uses a right-chained basket (right-hand sum) to approximate inflation, which is strictly less accurate than the PCEPI's use of the trapezoid rule. (The bad approximation has stuck with us for what are essentially political reasons.)

The PCEPI is the metric recommended by the Federal Reserve, and the metric it pays attention to when it decides monetary policy; as a result, I suggest replacing CPI with PCEPI in this template. Does this sound reasonable? –Sincerely, A Lime 18:25, 15 May 2024 (UTC)

A Lime, yes, though I would perhaps suggest adding another template rather than replacing the current one, for two reasons. Firstly, I assume CPI data goes back further and might be necessary for obtaining data from certain years, secondly there may be cases where one methodology is more appropriate than the other. Zoozaz1 (talk) 21:12, 18 May 2024 (UTC)

I know the PCEPI has been reconstructed going back to at least 1929, which is roughly the same point as where CPI figures become reliable enough to be usable. –Sincerely, A Lime 21:50, 18 May 2024 (UTC)

Cents > dollars
