A COMPARISON OF CONDITIONAL AND UNCONDITIONAL APPROACHES IN VALUE‐AT‐RISK ESTIMATION*

In this paper, we attempt to find the most important factor causing the differences in the performance of Value‐at‐Risk (VaR) estimation by comparing the performances of conditional and unconditional approaches. For each approach, we use various methods and models with different degrees of flexibility in their distributions including S_U‐normal distribution, which is one of the most flexible distribution functions. Our empirical results underscore the importance of the flexibility‐of‐distribution function in VaR estimation models. Even though it seems to be unclear which approach is better between conditional and unconditional approaches, it seems to be clear that the more flexible distribution we use, the better the performance, regardless of which approach we use.     

Learning about Mutual Fund Managers

We study capital allocations to managers with two mutual funds, and show that investors learn about managers from their performance records. Flows into a fund are predicted by the manager's performance in his other fund, especially when he outperforms and when signals from the other fund are more useful. In equilibrium, capital should be allocated such that there is no cross‐fund predictability. However, we find positive predictability, particularly among underperforming funds. Our results are consistent with incomplete learning: while investors move capital in the right direction, they do not withdraw enough capital when the manager underperforms in his other fund.     

Your Privacy Is Sealed: Effects of Web Privacy Seals on Trust and Personal Disclosures

Online privacy is an issue of increasing national importance, and voluntary privacy seals provided by third‐party organizations such as TRUSTe and BBBOnline have been proposed as a means of assuring consumer privacy. Few studies have examined privacy seal effects. This study presents results of an online experiment that evaluated consumer response to privacy seals in a naturalistic exposure setting. Findings suggest that privacy seals enhance trust in the Web site and expectations that the site would inform the user of its information practices. While concern for privacy‐threatening information practices had no influence, privacy self‐efficacy, confidence in ability to protect one's privacy, moderated seal effects. Implications for the continued role of privacy seals are discussed.     

REGULATORY FORBEARANCE AND DEPOSITOR MARKET DISCIPLINE: EVIDENCE FROM SAVINGS BANKS IN KOREA

This paper investigates whether regulatory forbearance for savings banks in Korea affects the market discipline of depositors using data from 2000 to 2010, which are characterized by a series of exits of savings banks. We find that depositors' sensitivity to the savings banks' asset quality decreases when there is regulatory forbearance for failing savings banks. This forbearance effect is also observed in the behavior of the depositors of the neighboring savings banks in the same business area. These results suggest that regulatory forbearance may cause depositors to misjudge bank risks, increasing the expected costs of bank failure. (JEL G21, G28)     

What Matters to Individual Investors? Evidence from the Horse's Mouth

We survey a representative sample of U.S. individuals about how well leading academic theories describe their financial beliefs and decisions. We find substantial support for many factors hypothesized to affect portfolio equity share, particularly background risk, investment horizon, rare disasters, transactional factors, and fixed costs of stock market participation. Individuals tend to believe that past mutual fund performance is a good signal of stock-picking skill, actively managed funds do not suffer from diseconomies of scale, value stocks are safer and do not have higher expected returns, and high-momentum stocks are riskier and do have higher expected returns.     

The Riskiness of Large Audit Firm Client Portfolios and Changes in Audit Liability Regimes: Evidence from the U.S. Audit Market*

We investigate whether the financial riskiness of large U.S. audit firm clienteles varied with the changing audit litigation liability environment during the period 1975‐99. Partitioning the period of study into four distinct periods (a benchmark period (1975‐84), a period of increasing concerns about litigation liability (1985‐89), a period of lobbying for reform (1990‐94), and a post‐relief period (1995‐99)), we find some evidence of risk decreases during 1985‐89, strong evidence of risk decreases during 1990‐94, and strong evidence of risk increases during 1995‐99. However, we also find that over the period of our study, a time during which Big 6 market shares grew appreciably, the proportion of litigious‐industry clients in Big 6 client portfolios grew at about the same rate as the proportion of such clients in the population. Moreover, the Big 6 share of the financially riskiest clients in the economy did not grow as fast as the overall Big 6 market share. In sum, although our evidence is consistent with the hypothesis that the riskiness of Big 6 client portfolios responded to changes in the audit litigation liability environment, we find no systematic evidence of a "race to the bottom" or "bottom fishing" by these firms in a bid to increase their market shares.     

The Effect of Providing Peer Information on Retirement Savings Decisions

Using a field experiment in a 401(k) plan, we measure the effect of disseminating information about peer behavior on savings. Low‐saving employees received simplified plan enrollment or contribution increase forms. A randomized subset of forms stated the fraction of age‐matched coworkers participating in the plan or age‐matched participants contributing at least 6% of pay to the plan. We document an oppositional reaction: the presence of peer information decreased the savings of nonparticipants who were ineligible for 401(k) automatic enrollment, and higher observed peer savings rates also decreased savings. Discouragement from upward social comparisons seems to drive this reaction.     

Precautionary Saving of Chinese and U.S. Households

We employ a model of precautionary saving to study why household saving rates are high in China and low in the United States. The use of recursive preferences gives a convenient decomposition of saving into precautionary and nonprecautionary components. Over 80% of China's saving rate and nearly all U.S. saving arises from the precautionary motive. The difference between U.S. and Chinese household income growth rates is vastly more important than income risk for explaining the saving rates. The key mechanism is that precautionary savers have target wealth‐to‐income ratios, and rapid income growth necessitates high saving rates to maintain the ratio.     

Cross‐Border Bank M&As and Risk: Evidence from the Bond Market

The impact of cross‐border bank M&As on bank risk remains an open question. Though geographically diversifying bank M&As have the potential to reduce the risk of bank insolvency, they also have the potential to increase that risk due to the increase in risk‐taking incentives by bank managers and stockholders following these transactions. This paper empirically investigates whether cross‐border bank M&As increase or decrease the risk of acquiring banks as captured by changes in acquirers' yield spreads. This paper also investigates how differences in the institutional environments between bidder and target countries affect changes in yield spreads following M&A announcements. The study finds that bondholders, in general, perceive cross‐border bank M&As as risk‐increasing activities, unlike domestic bank mergers. Specifically, on average, yield spreads increase by 4.13 basis points following the announcement of cross‐border M&As. This study also finds that these yield spreads are significantly affected by the differences in investor‐protection and deposit insurance environments between the transacting countries. However, the study does not find that the regulatory and supervisory environment in the home countries of the transacting parties significantly affects the changes in yield spreads. The overall evidence suggests that regulators should judge the relative environment in both the home and the host countries in evaluating the associated risks of an active multinational financial institution and in setting the sufficiency of the banks' reserve positions.
