Purpose – The aim of this paper is to describe, analyze and explain the level of compliance of accounting practices with legislation and generally accepted accounting principles (GAAP) within the Swedish water and sewerage sector. Design/methodology/approach – The empirical data are based on a document study of the annual full cost accounting reports for the financial year 2010. We obtained complete data from 250 of Sweden's 290 municipalities. The data are analyzed by statistical methods. The explanations are based on an institutional theory. Findings – Most of the organizations surveyed in this study had taken measures in line with the new regulations, but none of them had adapted fully to the new requirements. Thus, we suggest that the industry has responded to the new regulation by compromise and avoidance. The statistical analyses show that compliance with legislation and GAAP is associated with legal form, minority governance, fee, tax base, population growth and audit firm. Research limitations/implications – This paper provides insight into the factors that explain compliance with accounting regulation. Future research would benefit from researching the decision process when organizations choose to comply or not to comply with specific accounting regulations in the public sector. Originality/value – Few prior studies focus on the actual compliance of accounting practices at the municipal level in relation to accounting regulation and the factors that explain the level of compliance. Knowledge of the factors that explain compliance to accounting regulation will benefit from future policy decisions on regulation and auditing of public sector accounting.

With the purpose of explaining professional audit costs in Swedish municipalities, we hypothesised that audit costs are partly driven by various signalling and monitoring incentives in order to manage stakeholder relationships. Our model of the determinants of audit costs was tested on data from Swedish municipalities, thus extending the study of audit costs to political organisations in a Scandinavian institutional context. The test supported to some extent the traditional propositions of organisational complexity, risk and market determinants, as well as the proposition of the political environment. Our results indicate that audit costs are used to signal accountability, thereby suggesting that audit as a signal could be managed without managing professional auditors.

Previous research on the private sector shows that auditors and auditing firms are important actors in ensuring high-quality reporting based on accrual accounting. The aim of this study is to explore whether audit firms and audit costs/fees influence municipalities' probability of applying earnings management in their annual accounts. The empirical data, which covered the financial years 2011-2013, were handpicked from annual reports or retrieved from other sources. In general, our study shows that the probability of earnings management increased if audit costs/fees increased. However, there were differences regarding the probability of earnings management relating to which audit firm that was engaged. This implies that audit quality is a factor that affects the probability of earnings management in Swedish municipalities. The study also indicates that different audit firms make different trade-offs between professional versus commercial logics, and that this is reflected in the clients' propensity to engage in earnings management.

In this paper, renewal costs for railway tracks are investigated using survival analysis. The purpose is to derive the effect from increased traffic volumes on rail renewal cycle lengths and to calculate associated marginal costs. A flow sample of censored data containing almost 1 300 observations on the Swedish main railway network is used. We specify Weibull accelerated failure time regression models, and estimate deterioration elasticities for total tonnage as well as for passenger and freight tonnages separately. Marginal costs are calculated as a change in present values of renewal costs from premature renewal following increased traffic volumes. The marginal cost for aggregate freight and passenger tonnage is estimated to approximately SEK 0.002 per gross ton kilometre.
