We study medical practice variations for nine hospital treatments in the Netherlands. Our panel data estimations include various control factors and physician’s role to explain hospital treatments in about 3,000 Dutch zip code regions over the period 2006–2009. In particular, we exploit the physicians’ remuneration difference—fee-for-service (FFS) versus salary—to explain the effect of financial incentives on medical production. We find that utilization rates are higher in geographical areas where more patients are treated by physicians that are paid FFS. This effect is strong for supply sensitive treatments, such as cataracts and tonsillectomies, while we do not find an effect for non-supply sensitive treatments, such as hip fractures.
The value of implicit guarantees has declined from its peak at the height of the financial crisis, which is consistent with progress made regarding the bank regulatory reform agenda, as one would expect that many of the reform measures imply a more limited value of implicit guarantees for bank debt. Implicit guarantees persist however and their value continues to be significant, estimated here to be equivalent to EUR 50 billion of annual funding costs savings for a sample of more than 100 large European banks. This estimated funding cost advantage is a conservative estimate as it only focuses on one type of debt that can be measured in "real-time", that is as data on credit ratings, debt issuance and prices of debt become available. In any case, bank debt continues to be considered "special" by market participants and this observation implies that the substantial economic distortions, including distortions to risk-taking incentives and competition, arising from this situation also persist.
We estimate the size of the annual funding advantage for a sample of 151 large European banks over the period 1-1-2008 until 15-6-2012 using rating agencies" assessment of banks" creditworthiness with and without external support. We find that the size of the funding advantage is large and fluctuates substantially over time. For most countries it rises from 0.1% of GDP in the first half of 2008 to more than 1% of GDP mid 2011. Our results are comparable to findings in previous studies. We find that larger banks enjoy on average higher rating uplifts, but the effect of size does not increase anymore for banks with total assets above 1,000 billion Euro compared to banks with assets between 250 and 1,000 billion Euro. In addition, a higher sovereign rating of a bank"s home country leads on average to a higher rating uplift for that bank.
