social sphere with the efficiency of a market economy
(Ludz, 1977).
2 MATERIALS AND METHODS
This study is focused on the economic development
of the countries of the German world which
comprises German-speaking countries and countries
are exposed to the German institutions and culture.
The study does not include the American countries of
German migration, in which the influence of the
culture and institutions of their former metropolises is
more significant, and the former German colonies,
which practically did not inherit the institutions of the
German Empire and gained independence from other
countries, and data for the colonial period of their
relations with Germany have not been found.
The features of the policy of economic
development and their results in the historical
retrospective of 1850-2020 are under study.
A feature of the research methodology is the use
for assessing economic development, besides the
usual indicators of economic growth (growth rates of
real GDP), also indicators of stability (risks) of this
development - the standard deviations (here and after
SD) of the growth rates of real GDP. The risk
assessment period is defined as the economic cycle
from the first year of the start (or acceleration) of
economic growth to the last year of the recession (or
slowdown) in Germany. This approach allows us to
assess the quality of economic decisions and their
implementation within the specific culture of the
German world.
For the purposes of analysis, economic cycles are
combined into four historical periods:
imperial period - 7 cycles - until 1919;
period of the Weimar Republic and the Third
Reich - 3 cycles - until 1946;
the period of division into two states (FRG and
GDR) - 5 cycles - until 1990;
the period of united Germany - 3 cycles - until
2020.
Within this approach, the policy of economic
development is considered to be as progressive when
the subsequent period, in comparison with the
previous one, has a higher rate of growth of
macroeconomic indicators and a lower rate of risk
(SD). On the contrary, decreasing in growth and
increasing in risks are associated with the regressive
policy of economic development. A mutual decline in
growth rates and risks is the indicator of the
conservative policy of economic development, and in
the case of growth, it is aggressive.
The index of coincidence of the development
policies of Germany with the countries of the German
world is calculated by the formula (1).
IC M O N 100
⁄
%,
(1)
where:
IC is an index of coincidence of development
policies, for convenience on the percentage,
N is the total number of studied periods (economic
cycles),
M is the number of coincidences of development
policies,
O is the number of opposite development policies.
This approach is theoretically substantiated in
earlier studies by the authors, which shows the
correlation between culture and institutional models,
which is confirmed by econometric studies of
economic development (Savelyev, 2015; Savelyev,
2020; Savelyev et al., 2020a, 2020b; Savelyev et al.,
2021a, 2021b, 2021c, 2021d). Data sources were
works (Maddison, 2008; Bolt, van Zanden, 2014;
World Bank, 2019; TED, 2020).
Information base for the analysis of data on the
Russian Empire – Nominal GDP historical series
(Dincecco, 2013). This source contains data on
nominal GDP. For correct comparison for the period
1900-1913 according to (Maddison, 2008), the
average annual inflation index was evaluated and the
values of nominal GDP reduced by this index were
obtained. This indicator can be considered the closest
analogue of real GDP. Actual inflation by years may
differ significantly, but for the purposes of this work,
longer periods than a year are studied, and deviations
of real GDP from the calculated one due to the
deviation of the actual annual inflation index from the
average annual level are leveled, which allows us to
calculate growth data reduced by the average annual
inflation nominal GDP comparable to real growth.
3 RESULTS AND DISCUSSION
The evaluation of the development policy during the
periods of certain economic cycles in the studied
countries is presented in Table 1. Analysis of the
evaluation of the coincidences of policies and
opposite policies in these periods is made in Table 2.
