Abstract
We examine how institutional saving mechanisms influence retirement saving decisions under bounded rationality and income risk. Using a life-cycle experiment with habit formation and loss aversion, we test mandatory and voluntary binding savings under deterministic and stochastic income. Voluntary commitment improves saving performance only when income is predictable; under uncertainty, it fails to improve performance. Mandatory savings do not raise total saving, as participants reduce voluntary contributions. These results emphasize the role of income smoothing in enabling behavioral interventions to improve long-term financial outcomes.

Tax Authority Attention and Financial Reporting

Abstract
We study the effects of Tax Authority (IRS) attention on a firm’s financial reporting. We explore whether firms institute a higher degree of accounting conservatism in response to IRS monitoring. Using data on IRS acquisition of public firms’ 10-K financial disclosures to proxy for IRS attention, we find that when firms are under IRS attention, they tend to initiate higher levels of unconditional and, to some extent, conditional accounting conservatism. We alleviate some of the endogeneity concerns by using pre- and post-IRS attention environments between the treated group (firms with IRS attention) and a propensity score that matches the control group of firms (no IRS attention). These results withstand several robustness tests and subsample analyses.

Private ownership boosts hospital performance
New research by the Halle Institute for Economic Research (IWH) and ESMT Berlin shows that private equity (PE) acquisitions lead to substantial operational efficiency gains in hospitals, challenging common public concerns. The study reveals that hospitals acquired by PE firms significantly reduce costs and administrative staff without increasing closure rates or harming patient care.
