Abstract: We study how US manufacturing firms' investment responds to tariff reductions in supplier industries. Our estimates, based on tariff reductions following multinational trade agreements, suggest that a hypothetical 10% reduction of all upstream tariffs would increase downstream investment by 4% to 6%. This estimate is not explained by decreasing uncertainty and stems from tariff reductions for homogeneous and low-R&D inputs, consistent with the investment response resulting from cost reductions rather than superior foreign technology embodied in imported inputs. Evidence from an instrumental variable estimation using the sudden increase in Chinese import penetration suggests that import competition also increases downstream investment.

Abstract: Using data on the registration of clinical trials and the disclosure of trial results, we examine how firms respond to peer disclosures. We find that firms are less likely to disclose their own trial results if the results of a larger number of closely related trials are disclosed by their peers. This relation is stronger if the firms face higher competition (as measured by the number of competing trials). It is weaker if the firms are further along in their research than the peers (as measured by the trials’ phase) and if the peers’ disclosures convey more negative news (as measured by the firms’ stock price reaction). We also find that firms are more likely to abandon ongoing trials if a larger number of peers disclose the results of closely related trials. Additional tests suggest that this real effects channel does not drive the impact on the firms’ disclosure decisions.

Abstract: There is a discrepancy between CAPM-implied and realized returns. Using the CAPM in capital budgeting -- as recommended in textbooks -- should thus have real effects. For instance, low beta projects should be valued more by CAPM-users than by the market. We test this hypothesis using M&A data and show that bids for low-beta private targets entail lower bidder returns. We provide further support by testing several ancillary predictions. Our analyses suggest that using the CAPM when valuing targets leads to valuation errors (relative to the market's view) corresponding on average to 12% to 33% of the deal values.

The Accounting Review Vol. 96, No. 1 (2021), 377-400
Abstract: We examine the relation between accounting quality and debt concentration in corporate capital structures (i.e., firms’ tendency to rely predominantly on only a few types of debt). Motivated by theoretical and empirical research that supports a strong link between debt concentration and creditors’ coordination costs and the importance of accounting quality in reducing these costs, we hypothesize that firms with higher accounting quality have less concentrated debt structures. Measuring accounting quality with a comprehensive index based on the occurrence of material internal control weaknesses, accounting restatements, SEC AAERs, and firms’ reliance on small auditors, we find that higher accounting quality is indeed associated with less concentrated debt structures. This relation is stronger for firms with higher default risk, as the probability that creditors need to coordinate is higher, and for firms with lower liquidation values, as creditor coordination to avoid liquidation is more important.

Abstract: Coordination failure among owners of heterogeneous debt types increases distress costs. Covenants reduce expected distress costs by lowering the probability of liquidity shortages, increasing liquidation values, and incentivizing creditor monitoring. We predict and find that new debt contracts include more covenants when borrowers' existing debt structures are more heterogeneous. Our findings suggest that covenants are not only used to address creditor-shareholder conflicts but also to reduce the expected costs of coordination failure among creditors. Further, our results indicate a dynamic component missing from static debt structure models: Debt heterogeneity entails additional covenants (i.e., constraints) when raising future debt.

Abstract: We examine how mark-to-market accounting affects the investment decisions of managers with reputation concerns. Reporting the current market value of a firm's assets can help mitigate agency problems because it provides outsiders (e.g., shareholders) with new information against which the management's decisions can be evaluated. However, the fact that the assets' market value is informative can also have a negative side effect: Managers may shy away from investments that indicate conflicting private information and would damage their reputation. This effect can lead to inefficient investment decisions and make marking to market less desirable when market prices are more informative.

Abstract: I study the effect of chief executive officer (CEO) optimism on CEO compensation. Using data on compensation in US firms, I provide evidence that CEOs whose option exercise behavior and earnings forecasts are indicative of optimistic beliefs receive smaller stock option grants, fewer bonus payments, and less total compensation than their peers. These findings add to our understanding of the interplay between managerial biases and remuneration and show how sophisticated principals can take advantage of optimistic agents by appropriately adjusting their compensation contracts.

Abstract: The Sarbanes-Oxley Act (SOX) was passed in the wake of several scandals that rocked corporate America in 2001 and 2002. The objective behind SOX was to improve corporate governance by improving accounting disclosures. Compliance with Section 404 is considered by many to be the most costly requirement of SOX and has been argued to be a disproportionate burden for small firms. Consequently, firms with a public float below $75 million were granted several exemptions from compliance. We document an unintended effect of these exemptions: a weakening of corporate governance through a weakening of the market for corporate control.
A New Approach to the Measurement of Polarization for Grouped Data
(with Eckart Bomsdorf)
AStA Advances in Statistical Analysis Vol. 91 (2007), 181-196
Abstract: In this paper, we develop a measure of polarization for discrete distributions of non-negative grouped data. The measure takes into account the relative sizes and homogeneities of individual groups as well as the heterogeneities between all pairs of groups. It is based on the assumption that the total polarization within the distribution can be understood as a function of the polarizations between all pairs of groups. The measure allows information on existing groups within a population to be used directly to determine the degree of polarization. Thus, the impact of various classifications on the degree of polarization can be analysed. The treatment of the distribution's total polarization as a function of pairwise polarizations allows statements concerning the effect of an individual pair or an individual group on the total polarization.
