I recently heard someone mention an arbitrage strategy involving selling freshly issued bonds and buying the "old batch" as it has shown that the liquidity in the fresh batch motivates/drives up these prices though everything else is equal. It was supposedly used extensively by Long-term Capital Management (LTCM) in the 90ies with extreme leverage and is common knowledge in the industry.
What is the phenomena called and where can I read more about it? Papers with examples and data are highly appreciated.
