Spain Economy Watch is a weblog - run by Edward Hugh - which is dedicated to following the day to day progress of the Spanish economy as part of the eurozone system. The Weblog arose out of my curiosity concerning how the system operated in connection with the evident demographic patterns which are to be found among the various member states of the zone. The roots of the particular mix of economic problems which some of these economies now seem to be facing, in particular in association with the ending of the construction boom, about what can be done to address these problems, and about what might be learnt from studying the situation as it evolves.Spanish society shares in common with the other Southern European zone members a historically unprecedented combination of structural problems stemming from a very rapid decline in fertility and increase in life expectancy - both of which tend towards a situation of rapid population ageing. One consequence of the fertility decline is that there is often now insufficient insufficient domestic labour supply to meet the growth needs of these societies, needs which are only reinforced by the weight of the pensions liabilities which are now imminently pending. The impact of this has been a considerable migration inflow which has both been fueled by and in turn has fueled a construction boom.Needless to say none of these problems were ever really contemplated when the present generation of economic textbooks was written. Dealing with this whole problem set has become a most pressing concern, both theoretically and practically.A great deal more background and information about the theoretical perspective which informs this blog may be found over at the Demography Matters blog.
