I would like to come back to the much discussed
issue of internal devaluation. As in every debate there two sides here and each
one of them is very much sure of their arguments.
Internal devaluation has more chances to
succeed, the bigger the tradable sector (and the more export-oriented it is) of
the affected country is and the smaller the country’s dependence on domestic
demand. This is based on the fact that internal devaluation (i.e. among others,
the slashing of wages to improve competitiveness) adversely affects domestic
demand, hence the affected country’s chance of having a “soft” (or “relatively softer”
if you prefer) landng is higher the larger its external sector is.
The sample of countries that have enacted an
internal devaluation strategy is limited (or maybe the number of those that I’m
aware of is) so I don’t know if what I’ve tried to do in this post is
statistically proper. The countries that comprise my sample are Estonia,
Greece, Ireland, Latvia and Lithuania. I’ve left out Germany since it is a
large economy and large economies tend to have lower export ratios (as % of
GDP), Hungary because in this case the strategy was halted abruptly and Portugal
since they joined the “internal devaluation club” much later than the rest, in
the middle of 2011 and a full year has not yet lapsed. Greece entered an
agreement with IMF and the EU on May 2010, while Ireland did so on November
2010. The Baltic countries started their internal devaluation adjustments in
2009. Running regressions with 5 observations is without doubt not
statistically proper but my intention is just to try to showcase the
relationship between the two variables.
I used average real GDP growth for the years following
the initiation of an internal devaluation strategy irrespectively for when
IMF/EU programs were terminated (except of course if they were unilaterally terminated
like in the case of Hungary) or for the cases where a country initiated such a strategy
on its own accord.
My intention is to have a go at showing which
fundamental characteristics of an economy may increase the chances of success
of the internal devaluation strategy.
There are some inconsistencies in my
methodology but these are due to a sheer lack of data. For example, I used the
World Bank Ease of Doing Business Index for 2010 and 2011 even though I refer
to real GDP growth for the 2009-2011 interval. I had some data for the said
index dating back to 2009 but since these cannot be found anymore in the World Bank
website I guess that this means that they are no longer valid. I would be
grateful, if someone that knows differently said so in the comments section. As
a reminder this index is actually a rank so a value closer to 1 means a better
ranking.
To control for the economies’ fundamentals I
used Domestic Demand for year 2008 (right before the global recession acquired
full force status) and Exports for year 2008. This way I want to highlight the
importance of a country’s fundamentals, before they embarked on their
respective internal devaluations and before the current depression.
Enough with the intro then, I should let the
charts roll in.
As a legend, I should say that the light blue
dot is for Estonia, the dark blue dot is for Greece, the green dot is for
Ireland, the dark red dot is for Latvia and the yellow dot is for Lithuania.

As you can see the cumulative decrease in real
GDP tends to be smaller in countries where domestic demand accounts for a
smaller chunk of GDP.

It seems to
me that indeed, countries with a larger external sector experienced a smallest
overall decrease in real GDP from their pre-recession levels.
source: Eurostat, World Bank, own calculations |
It seems
that there is a positive relationship between the Ease of Doing Business
rankings and real GDP growth.
I next want
us to have a look at the interaction between changes in employment after the
internal devaluation strategies were initiated and the countries’ rankings in
the Ease of Doing Business survey.
source: Eurostat, World Bank, own calculations |
The scatter
plot shows that there is a positive relationship between the perceived business
environment and changes in employment. Now let’s have a look at unemployment.
source: Eurostat, World Bank, own calculations |
It seems that
changes in unemployment exhibit a negative relationship with the countries’
rankings in the Ease of Doing Business survey (or actually a positive survey if
we take rankings literally but since a higher ranking number is negative I
think it’s best to say that they exhibit a negative relationship).
Since averages
may well hide sizeable divergences among values comprising the samples (if one is
so charitable to call what I’ve used here as samples) I would like to finish
the post with some charts showing actual values for the figures used in the
regressions above.
Here’s real
GDP growth.
source: Eurostat |
Here’s employment.
source: Eurostat |
And this is
unemployment.
source: Eurostat |
Here are
exports as a % of GDP.
source: Eurostat |
And here is
Domestic Demand.
source: Eurostat |
Finally,
here are the World Bank Ease of Doing Business Index rankings.

Let me wrap this up. Since this is a highly
politicized issue I wouldn’t like to make any further comments, I’ll let you
draw your own conclusions from the charts. I hope that you’ve got this far and
the ridiculous amount of charts didn’t put you off.
really nice charts
ReplyDeleteenjoyed domestic demand, unemployment (where greece goes sky high)
waiting for more comments
Thank you for reading this and I'm glad that you liked the charts..I think it's more than obvious that I too take a particular liking in 'em...;-)

update and add PS+Italy in unempl.15-64
i would like to check domestic demand over eurozone
