This paper studies an economy in which firms can operate either a mature or a new technology and lenders acquire information on the productive assets of the borrowing firms that are eligible as collateral. We demonstrate that when contracts are imperfectly enforceable informed lenders offer inexpensive funding for the mature technology but may choose not to finance the new one, seeking to preserve the value of their information on the mature assets. Using firm-level data from Italy, we find that banks that establish long-term relationships with firms promote technological progress on average. However, we find that relationship banks inhibit innovations that entail a large depreciation of existing technology-specific information such as radical innovations.
