COST-VOLUME-PROFIT ANALYSIS UNDER UNCERTAINTY WHEN THE FIRM HAS PRODUCTION FLEXIBILITY

This study examines the behavior of the firm which faces uncertainty in demand but can adjust its output once the uncertainty is resolved, using contingentclaims analysis. The paper finds that (i) the optimal output of the firm with ex post adjustment capability is less than that of the firm without production flexibility; (ii) the optimal ex ante output increases with the higher interest rate; (iii) the greater the marginal cost associated with the expost adjustment and/or salvage value, the greater the optimal ex ante output; and (iv) the effect of demand volatility and production lead time on the optimal ex ante output could be either positive or negative. Based upon the study's findings, some important managerial decision implications are discussed.     

THE USE OF MULTIPLE INSTRUMENTS FOR MEASUREMENT OF EARNINGS FORECAST ERRORS, FIRM SIZE EFFECT AND THE QUALITY OF ANALYSTS'FORECAST ERRORS

This paper develops an instrumental variables framework to form a better proxy for earnings forecast errors. The key aspect of the approach is to extract information from alternative proxies for the same underlying variable, namely a portion of realized earnings signals unexpected by the market. We use signs of various proxies for earnings forecast errors obtained from different time-series forecasting models as multiple instruments. The results show that the instrumental variables approach is effective for reducing measurement errors inherent in various proxies for earnings forecast errors. It produces not only a smaller magnitude but also a narrower dispersion of earnings forecast errors. The paper provides evidence that the instrumental variables approach performs better for small-firm samples than for large-firm samples. Finally, we observe that analysts' forecast errors seasoned with the signs of various time-series forecast errors (as well as the signs of their own forecast errors) outperform those without seasoning. This indicates that analysts' forecast errors can still be improved by employing the instrumental variables technique.     

Managerial legal liability coverage and earnings conservatism

This paper examines the effect of managerial legal liability coverage on earnings conservatism. Using directors’ and officers’ (D&O) liability insurance coverage and cash for indemnification as a proxy for managerial legal liability coverage, we find that the higher the managerial liability coverage, which reduces the expected legal liability of managers, the less conservative the firm's earnings. We also find that managerial legal liability coverage has a stronger influence on earnings conservatism in a legal regime with higher litigation risk. Our results are consistent with the threat of litigation conditioning managers to practice conservative accounting.     

Investor protection, adverse selection, and the probability of informed trading

The purpose of this study is to investigate the relation between investor protection, adverse selection, and the probability of informed trading. Previous research has established a direct relation between investor protection and firm liquidity, measured by bid-ask spreads and depths. In this study, we test the hypothesis that adverse selection is the mechanism through which poor investor protection leads to higher costs of liquidity. The Hong Kong equity market provides a unique opportunity to compare adverse selection differences across distinct investor protection environments, holding constant the trading platform and currency. Using various bid-ask spread decomposition models and probability of informed trading estimates, we confirm the hypothesized relation between investor protection quality and adverse selection costs. These findings contribute to the literature by establishing one of the links in the chain connecting investor protection to firm valuation.

Institutional Investor Trading in a Short Investment Horizon: Evidence from the Korean Stock Market

We examine the weekly trading activities of institutional investors in the Korean stock market. First, we find that average net trades by institutional investors this week are negatively related to one-week lagged returns, suggesting that they could be contrarian traders. Second, our finding shows that institutional investors’ net trades this week are positively related to the net trades next week, consistent with persistent trading and/or herding behavior. Third, we find that institutional net trades are positively related to the post one-week returns. Finally, our findings are most pronounced in the group of short-term institutional investors.     

When Do Employees Cyberloaf? An Interactionist Perspective Examining Personality,Justice, and Empowerment

Cyberloafing—using the Internet for non‐work‐related activities—is a prevalent counterproductive work behavior in the workplace, but researchers have not yet paid sufficient attention to this issue, especially related to the role of personality in cyberloafing. Recognizing such a research gap, and using a trait activation theory framework, this study examines whether conscientiousness and emotional stability negatively relate to cyberloafing. We further investigate how organizational justice perceptions and psychological empowerment moderate the negative relationship between these personality traits and cyberloafing. Based on a sample of 247 employees, we find that those high in conscientiousness cyberloaf less when they perceive greater levels of organizational justice. In addition, highly conscientious individuals cyberloaf less when they have low, rather than high, levels of psychological empowerment. Implications for research and practice as well as future research directions are discussed. © 2015 Wiley Periodicals, Inc.     

Wage Discrimination Against Workers with Sensory Disabilities

We link information on occupation‐specific job demands to data from the Survey of Income and Program Participation to provide first‐ever estimates of wage discrimination against workers with sensory disabilities. Estimates are derived from wage models that control for job demands related to sensory abilities, and interactions between job demands and workers' sensory limitations. Results indicate approximately one third (one tenth) of the male (female) disability‐related wage differential is potentially attributed to discrimination. The results differ from estimates of discrimination against workers with physical disabilities obtained with similar methods, underscoring the importance of accounting for heterogeneity of the disabled population in discrimination studies.     

Location strategies for agglomeration economies

Because agglomeration economies may create competitive advantage and each location has a unique array of agglomeration economies, where should firms locate? We combine fundamental economic and strategy concepts to: (1) determine when firms must locate proximately to access factor pools; (2) show that factor pools controlled by fewer firms are less useful to new entrants; and (3) demonstrate that certain firms risk aiding competitors when contributing to efficient factor pools. We find support for our predictions with a test on new U.S. manufacturing entrants from 1985 to 1994, using an empirical specification that separates agglomeration levels from agglomeration economies.

Uncertainty,market structure,and liquidity

In this study we show that market uncertainty [measured by the Chicago Board Options Exchange Market Volatility Index (VIX)] exerts a large market-wide impact on liquidity, which gives rise to co-movements in individual asset liquidity. The effect of VIX on stock liquidity is greater than the combined effects of all other common determinants of stock liquidity. We show that the uncertainty elasticity of liquidity (UEL: percent change in liquidity given a 1% change in VIX) has increased around regulatory changes in the US markets that increased the role of public traders in liquidity provision, reduced the minimum allowable price variation, weakened the affirmative obligation of NASDAQ dealers, and abolished the specialist system on the NYSE.     

The determinants of interest margins and their effect on bank diversification: Evidence from Asian banks

An endogenous switching regression model is employed for this study, categorizing the banks into regimes of high and low degrees of diversification, with our results indicating that net interest margins can be less sensitive to fluctuations in bank risk factors for functionally diversified banks as compared to more specialized banks. In turn, this implies that by diversifying their income sources, these banks can reduce the shocks to net interest margins arising from idiosyncratic risk. Our results show that prior findings can hold when the banks are located in a regime with a low degree of diversification.
