Maintaining maintenance: The real effects of financial reporting for infrastructure

We use the adoption of General Accounting Standards Board Statement No. 34 (GASB 34) to examine whether disclosing information in states' financial reports influences their investment decisions. GASB 34 requires governments to report on general infrastructure assets and permits either the standard depreciation approach or the modified approach. The modified approach requires additional disclosures, a step which we argue promotes greater transparency about a government's infrastructure and can potentially facilitate infrastructure investment decisions. We find a robust positive association between the modified approach and investment in infrastructure maintenance. Additional evidence demonstrates a more pronounced effect when external monitoring is likely higher and government officials are likely better informed as a result of the increased disclosure. We further find that states using the modified approach are less likely to cut or divert funds intended for infrastructure maintenance. Our study suggests that disclosing information in governments' financial reports can have real effects, such as mitigating underinvestment in infrastructure maintenance, which governments often defer to future periods in violation of the interperiod equity principle and to the detriment of society.
