## Intro

This vignette documents now to identify the countries with max `gdppc` for each year, extract from that the major technology leaders, and plot them with annotations.

The Netherlands led the world in `gdppc` for 97 percent of the years between 1349 and 1807. Other major technology leaders since then have been England / Great Britain / the United Kingdom (`GBR`) and `USA` – and maybe others like Singapore. Let’s redo this starting from 1349 and excluding petrostates Qatar (`QAT`), Kuwait (`KWT`), and United Arab Emirates (`ARE`), plus Norway (`NOR`), which owes a substantial portion of their wealth to democratic management of North Sea oil.

Singapore (`SGP`) has replaced Norway as the current leader, according to the Maddison project data. The Wikipedia article on “List of countries by GDP (PPP) per capita” notes that data from the US Central Intelligence Agency report `gdppc` number for Monaco (`MCO`) and Liechtenstein (`LIE`) higher than Singapore and Norway. However, they are tiny countries with populations roughly 40,000 each without broad-based economies and are not included in `MaddisonData`. Luxembourg (`LUX`) has a population under a million. Let’s redo this analysis without `LUX`.

First, however, lets check on the early years for which data on Holland are available.

    NLDdat <- subset(MaddisonData, ISO=='NLD')
    head(NLDdat)

    ## # A tibble: 6 × 4
    ##   ISO    year gdppc   pop
    ##   <chr> <dbl> <dbl> <dbl>
    ## 1 NLD       1   NA    200
    ## 2 NLD    1000   NA    300
    ## 3 NLD    1348 1405.    NA
    ## 4 NLD    1349 1460.    NA
    ## 5 NLD    1350 1631.    NA
    ## 6 NLD    1351 1714.    NA

`MaddisonData` on Holland starts with year 1, then skips to 1000, then to 1348 before Holland becomes the leader in 1349.

Now let’s refine the analysis of `GDPpc` leaders, as indicated above.

    MadDat1349a <- subset(MaddisonData, (year > 1348) &
                           !(ISO %in% c('QAT', 'KWT', 'ARE', 'NOR', 'LUX') ))
    MadLdrs1349a <- MaddisonLeaders(data=MadDat1349a)
    (MadLdrsSum1349a <- summary(MadLdrs1349a, 'yearBegin'))

    ##     ISO yearBegin yearEnd   n          p
    ## NLD NLD      1349    1807 447 0.97385621

    ## AUS AUS      1853    1891  17 0.43589744
    ## NZL NZL      1873    1874   2 1.00000000
    ## USA USA      1882    2005 107 0.86290323
    ## CHE CHE      1931    2009   9 0.11392405
    ## SGP SGP      2010    2022  13 1.00000000

The Netherlands (`NLD`) was the leader for 97 percent of the years between 1349 and 1807, according to `MaddisonData`. Then England / Great Britain / the United Kingdom (`GBR`) led for 74 percent of the years between 1808 and 1898. Then `USA` led for 84 percent of the years between 1882 and 1990 with Australia (`AUS`), New Zealand (`NZL`) and Switzerland (`CHE`) leading for the remaining 16 percent of those years. Luxembourg (`LUX`) led between 1991 and 2008, then Switzerland (`CHE`) led for 2009, then Singapore (`SGP`) between 2008 and 2022.

How much did `gdppc` fall for `NLD` between 1807 and 1808?

    (NLD1808 <- subset(NLDdat, year %in% 1807:1808))

    ## # A tibble: 2 × 4
    ##   ISO    year gdppc   pop
    ##   <chr> <dbl> <dbl> <dbl>
    ## 1 NLD    1807 3863.    NA
    ## 2 NLD    1808 2632     NA

    (dNLD1808 <- diff(log(NLD1808$gdppc)))

    ## [1] -0.3836341

    expm1(dNLD1808)

    ## [1] -0.3186193

For simplicity, we focus on `NLD`, `GBR`, `USA`, and `SGP`. A few other countries (`AUS`, `NZL`, `CHE`, and `LUX`) led for so few years in this period that including them in this plot would likely add more complexity than information and make it harder to understand the big picture.

    NLD_SGP <- subset(MadDat1349, ISO %in% c('NLD', 'GBR', 'USA', 'SGP'))
    NLD_SGPsum <- MaddisonLeaders(data=NLD_SGP)
    summary(NLD_SGPsum, 'yearBegin')

    ##     ISO yearBegin yearEnd   n         p
    ## NLD NLD      1349    1807 459 1.0000000
    ## GBR GBR      1808    1934  80 0.6299213
    ## USA USA      1880    2006 119 0.9370079
    ## SGP SGP      2007    2022  16 1.0000000

    (NLD_SGP0 <- ggplotPath(y='gdppc', group='ISO', data=NLD_SGP, scaley=1000))

The line for the Netherlands shows a dramatic decline between 1807 and 1808. Before speculating further, let’s check the data sources used by `MaddisonData`:

    NLDrefs <- getMaddisonSources('NLD')

The prior to 1808 these data are for Holland [Van Zanden and van Leeuwen (2012)]. The more recent data are for the Netherlands [Smits et al. (2000)], of which Holland is only a part. That transition was during the Napoleonic wars, and the Netherlands became part of France for part of those times.

We want multiple annotations on this plot: - The `NLD` line as “Holland” (at `ggppc` = roughly $5K in 1600) and “Netherlands” (at `gdppc` = roughly $4K in 1900). - ‘English Civil War’, 1642-1652, during which King Charles I was decapitated (in 1649), after which `gdppc` for `GBR` began to increase; we could see that more clearly in a separate plot zooming in on that particular time.
- Queen Ann (1702-1714), who reigned over substantial turbulence in `gdppc` and was followed by slower but still impressive growth on `gdppc` relative to the economic stagnation before Charles I lost his head. - War of 1812 (1812-1815). - American Civil War (1861-1865). - `WW1` (1914-1918). - Herbert Hoover (1929-1933). - Franklin Roosevelt (1933-1945). - `WW2` (1939-1945). - Ronald Reagan. - The first presidency of Donald Trump. - Joe Biden.
