The paper ‘S-time-distance perspective: providing new insights of the current crisis from BTS
and GDP data’ prepared by P. Sicherl, J. Cirjaković, M. Remec was presented in the session
New Methods at the 30th CIRET Conference, New York, October 2010. The time distance
methodology deals here with the description of the current economic crisis with selected
indicators from the Business Tendency Surveys and GDP for EU and selected countries. This
makes it possible to analyse the severity of the crisis in the two dimensions: decrease in
the static index from the peak in 2008 and the S-time-distance lag indicating how many
years earlier the same levels of GDP were already achieved in the past.
The latter indicates that e.g. for EU27 this would amount to 3.3 years for 2009, 3.9 years
for 2010 and to 4.4 years for 2011. Alternatively, this means that the forecast level for 2011
would be lower than that achieved in 2007. On the other hand, S-time-distance measure
clearly shows how debt crisis has weakened the possibility of higher growth rate in the near
future. In 2011 the investment rate for EU27 would still be around 10% below 2008 value and
about at the level attained 14 years ago (about 1997 level). For the USA the investment rate in
2011 is expected to be about 13% below the 2008 value at a level before 1994 resulting in S-
time-distance of about 17 years. For investment rate Triad countries are expected to fall
back to the levels in past century which could not be perceived by looking only at the static
indexes.
Comparing maximum and minimum values of ESI and GDP in the period 2007-2009 shows
different development in the declining and recovery phases. ESI for EU27 started to decline
after June 2007, while GDP started to decline after first quarter of 2008, this means
8 months later than ESI. In the declining phase ESI offered a leading warning of about 8
months, showed a fall of about 21 months from the maximum in June 2007 to the minimum
levels in March 2009, while the fall in quarterly GDP from first quarter of 2008 lasted about
15 months. In the current crisis ESI showed much higher volatility than GDP. As mentioned
before, this may indicate that much greater decline of ESI than of GDP might be a sign
that the economic sentiment goes considerably beyond GDP and include also problems
related to the decrease in the investment rate, employment and other conditions.
The examples show that more attention needs to be paid to levels and time, which means
that S-time-distance can bring about additional information for a more thorough analysis and
understanding of the situation. An obvious extension would be to repeat such analysis for
the ESI components and also on types of indicators like OECD composite leading indicators.
There are lessons that can be learned with the new methodology from comparisons
across indicators and countries and lessons from a more detailed analysis within a given
country.
