We propose a new approach to estimating and testing asset pricing models in the context of a bilinear paradigm introduced by Kruskal 18 . This approach is both simple and at the same time quite general. As an illustration we apply it to the special case of the arbitrage pricing model where the number of factors is pre-specified. The data appear to be generally in conflict with a five or seven factor representation of the model used by Roll and Ross 30 . When we consider the number of replications of our test and the large number of observations on which it is performed, the frequency with which we reject the three factor APM does not lead us to conclude that this model is unrepresentative of security returns. Further, the rejection of the five and seven factor versions is to be expected if the three factor version is correct. The paradigm gives insight into the appropriate specification of the model and suggests that there may be a small number of economy wide factors that affect security returns. 相似文献

Financial Reporting and Supplemental Voluntary Disclosures 总被引:1,自引:0,他引:1
A standard result in the voluntary disclosure literature is that when the manager's private information is a signal correlated with the firm's liquidation value, mandatory disclosures substitute for voluntary disclosures. In this paper, we assume that the manager's private information complements the mandatory disclosure and show that the content and likelihood of a voluntary disclosure depend on whether the mandatory reports contain good or bad news. This different information asymmetry produces new, testable implications regarding the probability of and market reaction to voluntary disclosures. We also show that changes in mandatory disclosure regulations can have unintended consequences due to their effects on the manager's willingness to voluntarily provide supplemental disclosures. 相似文献

We generalize the unobserved components (UC) model to allow the permanent component to have different dynamics than the transitory components when decomposing U.S. economic activity using a multivariate UC model of (log) output, consumption, and investment. We find that these proposed dynamics in the permanent component are statistically significant and distinct from those of the transitory components. Our approach provides an alternative explanation for the growth cycles identified by Comin and Gertler ( 2006 ) that is related to the cyclical movements in technology, in a framework consistent with the Beveridge and Nelson ( 1981 ) decomposition. 相似文献

Why do negative credit events lead to long‐term borrowing constraints? Exploiting banking regulations in Peru and utilizing currency movements, we show that consumers who face a credit rating downgrade due to bad luck experience a three‐year reduction in financing. Consumers respond to the shock by paying down their most troubled loans, but nonetheless end up more likely to exit the credit market. For a set of borrowers who experience severe delinquency, we find that the associated credit reporting downgrade itself accounts for 25% to 65% of their observed decline in borrowing at various horizons over the following several years. 相似文献

The Fundamental Review of the Trading Book (FRTB) is the promised overhaul of bankmarket risk regulation. FRTB retains the authorized use of proprietary risk models, however, it introduces two additional criteria: (i) P&L attribution (PLA) tests and (ii) desk-level backtests. We examine empirically whether these additional criteria influence risk management and portfolio management practice, specifically portfolio construction and choice of risk model. We find that the PLA tests demand significant alignment with risk factors, however, the backtests do not incentivize use of superior risk models. This has important implications for the efficacy of the capital-based regulatory system. 相似文献

Maintaining sufficient liquidity in the financial system is vital for its stability. However, since returns on liquid assets are typically low, individual financial institutions may seek to hold fewer such assets, especially if they believe they can rely on other institutions for liquidity support. We examine whether state banks in the early 1900s took advantage of relatively high cash balances maintained by national banks, due to reserve requirements, to hold less cash themselves. We find that state banks did hold less cash in places where both state legal requirements were lower and national banks were more prevalent. 相似文献
