Audit Firm Tenure,Bank Complexity,and Financial Reporting Quality

Theory from organizations and economics research posits that in an inter‐organizational relationship, both parties invest in relationship‐specific knowledge, which in turn facilitates the effectiveness of the relationship while strengthening the attachment between the parties. In complex settings where there are more opportunities for knowledge creation, the investments will be larger and the attachment stronger. Because banks are complex institutions that present unique challenges to auditors, we suggest that effective audits critically depend on the accumulation of significant investments in client‐specific expertise through a long association with the client. We find a positive association between audit firm tenure and financial reporting quality, and this association is particularly strong in banks that are more complex. Also, contrary to recent research we find that benefits of audit firm tenure for complex banks accrue even for long tenure and are not limited to medium tenure. Our findings largely support the notion that a long relationship with the client reflects the underlying demand for expertise, which is critical for high‐quality audits of complex organizations. Imposing short‐term limits on audit firms would adversely affect the investments in client‐specific expertise especially in the cases where this expertise is needed the most. Our findings do not support calls for mandatory audit firm rotation for large complex institutions.     

Technological progress and regress in pre-industrial times

This paper offers micro-foundations for the dynamic relationship between technology and population in the pre-industrial world, accounting for both technological progress and the hitherto neglected but common phenomenon of technological regress. A positive feedback between population and the adoption of new techniques that increase the division of labor explains technological progress. A transient shock to productivity or population induces the neglect of some techniques rendered temporarily unprofitable, which are therefore not transmitted to the next generation. Productivity remains constrained by the smaller stock of knowledge and technology has thereby regressed. A slow process of rediscovery is required for the economy to reach its previous level of technological sophistication and population size. The model is employed to analyze specific historical examples of technological regress.
