Abstract In portfolio risk minimization, the inverse covariance matrix prescribes the hedge trades in which a stock is hedged by all the other stocks in the portfolio. In practice with finite samples, however, multicollinearity makes the hedge trades too unstable and unreliable. By shrinking trade sizes and reducing the number of stocks in each hedge trade, we propose a “sparse” estimator of the inverse covariance matrix. Comparing favorably with other methods (equal weighting, shrunk covariance matrix, industry factor model, nonnegativity constraints), a portfolio formed on the proposed estimator achieves significant out-of-sample risk reduction and improves certainty equivalent returns after transaction costs.

We pose good markets frictions on top of an otherwise standard two-country international real business cycle (IRBC) model. Shopping for goods takes effort, which prevents perfect matching between customers and producers. An increase in search effort implies increased measured productivity. Demand shocks increase expenditures and search effort simultaneously increasing output, consumption, productivity, and the trade deficit and appreciating the real exchange rate. Thus we solve the Backus-Smith puzzle and we show that the cross country correlation of consumption is higher than that of output. Standard IRBC models cannot account for these puzzles along with movements in TFP.

Abstract We examine the ability of three groups of informed market participants to anticipate the 2007–2008 financial crisis. Institutional investors and financial analysts exhibit some awareness of the impending crisis in their preference for nonfinancial stocks over financial stocks. In contrast, corporate insiders of financial firms appear to be completely unaware of the timing and extent of the financial crisis. Net purchases by managers of financial firms exceed those by managers of nonfinancial firms over the entire 2006–2008 period. Our results add considerable weight to the argument that the financial crisis was more a case of flawed judgment than flawed incentives.

We investigate the relative importance of various bankruptcy predictors commonly used in the existing literature by applying a variable selection technique, the least absolute shrinkage and selection operator (LASSO), to a comprehensive bankruptcy database. Over the 1980–2009 period, LASSO admits the majority of Campbell et al. (2008) predictive variables into the bankruptcy forecast model. Interestingly, by contrast with recent studies, some financial ratios constructed from only accounting data also contain significant incremental information about future default risk, and their importance relative to that of market-based variables in bankruptcy forecasts increases with prediction horizons. Moreover, LASSO-selected variables have superior out-of-sample predictive power and outperform (1) those advocated by Campbell et al. (2008) and (2) the distance to default from Merton’s (1974) structural model.

With superior information about their customers’ prospects, suppliers extend trade credit to capture future profitable business. We show that this information advantage generates significant return predictability. After controlling for major firm characteristics, firms that rely more on trade credit relative to debt financing have higher subsequent stock returns. The return predictability by trade credit is stronger among firms with lower borrowing capacity or profitability, and is more significant for firms with a higher degree of information asymmetry. Our findings suggest that trade credit extension reveals suppliers’ information that diffuses gradually across the investing public.

Abstract In this study, we examine how norms about the use of negotiation strategies by different parties in an auditor–client negotiation influence the relative efficacies of these negotiation strategies. We conduct an experiment with experienced auditors/financial managers as participants, who enter into a negotiation on an income‐decreasing audit adjustment with a hypothetical client/auditor who uses a strategy where the same concessions are given either at the start, gradually, or the end of the negotiation. We find that the concession‐end strategy is more effective than the concession‐start strategy when used by auditors; however, the reverse is true when these same strategies are used by financial managers. The concession‐gradual strategy leads to superior outcomes when used by either auditors or clients. We also provide evidence that auditors’ and financial managers’ perceptions of the norms relating to the use of these strategies correspond to what we propose in our theory.

We find that cash holdings are more valuable for firms disclosing material weaknesses in the Sarbanes–Oxley (SOX) 404 internal control assessments. We estimate that the value spread for firms with weak controls vs. effective controls is about $0.25 for an extra dollar of cash. Our results are not driven by account-level weaknesses but by more severe, company-level weaknesses in internal control over financial reporting (ICFR). Further, the economic consequences of cash resources significantly decrease with the remediation of previously reported material weaknesses. These results suggest that the favorable (precautionary) impact induced by weak ICFR appears to more than offset the adverse (agency) effect entailed by ineffective ICFR. Overall, our results survive alternative variable specifications, sample splits, matched sample analyses, and a variety of controls.
