Sparse Signals in the Cross‐Section of Returns

This paper applies the Least Absolute Shrinkage and Selection Operator (LASSO) to make rolling one‐minute‐ahead return forecasts using the entire cross‐section of lagged returns as candidate predictors. The LASSO increases both out‐of‐sample fit and forecast‐implied Sharpe ratios. This out‐of‐sample success comes from identifying predictors that are unexpected, short‐lived, and sparse. Although the LASSO uses a statistical rule rather than economic intuition to identify predictors, the predictors it identifies are nevertheless associated with economically meaningful events: the LASSO tends to identify as predictors stocks with news about fundamentals.     

Do External Auditors Perform a Corporate Governance Role in Emerging Markets? Evidence from East Asia

In emerging markets, the agency conflicts between controlling owners and the minority shareholders are difficult to mitigate through conventional corporate control mechanisms such as boards of directors and takeovers. We examine whether external independent auditors are employed as monitors or as bonding mechanisms, or both, to alleviate the agency problems. Using a broad sample from eight East Asian economies, we document that firms with agency problems embedded in the ownership structures are more likely to employ Big 5 auditors. This relation is evident among firms that raise equity capital frequently. Consistently, firms hiring Big 5 auditors receive smaller share price discounts associated with the agency conflicts. Also, we find that Big 5 auditors take into consideration their clients' agency problems when making audit fee and audit report decisions. Taken together, these results suggest that Big 5 auditors do have a corporate governance role in emerging markets.     

CUSTOMER POWER,STRATEGIC INVESTMENT,AND THE FAILURE OF LEADING FIRMS

Why might firms be regarded as astutely managed at one point, yet subsequently lose their positions of industry leadership when faced with technological change? We present a model, grounded in a study of the world disk drive industry, that charts the process through which the demands of a firm's customers shape the allocation of resources in technological innovation—a model that links theories of resource dependence and resource allocation. We show that established firms led the industry in developing technologies of every sort—even radical ones—whenever the technologies addressed existing customers' needs. The same firms failed to develop simpler technologies that initially were only useful in emerging markets, because impetus coalesces behind, and resources are allocated to, programs targeting powerful customers. Projects targeted at technologies for which no customers yet exist languish for lack of impetus and resources. Because the rate of technical progress can exceed the performance demanded in a market, technologies which initially can only be used in emerging markets later can invade mainstream ones, carrying entrant firms to victory over established companies.     

Financial Planner or Financial Counselor: The Differences are Significant

The authors argue that financial counseling and financial planning are significantly different professional fields when examined from both a theoretical and an applied perspective. The authors distinguish between these two professions with respect to the types of client problems presented, the criteria clients use for self-evaluation, and the services provided. As a consequence the authors recommend that a similar distinction be made with regard to the education and training programs associated with these professions.
