Unfortunately there are quite a few problems in the report:
1. it measures productivity by GDP, which itself is not a great measure
2. it compares Greece vs Germany, and fails to mention that they rely on completely different industries; Greek - agriculture, Germany - manufacturing
But what we are talking about here specifically is the software development industry, where quantity does not always mean quality. So herein lies the problem that potentially a lot of our beliefs that "more hours worked means diminished return" could just be based on bad data analysis.
