Strategies for Technological Innovation with Learning and Adaptation Costs

This paper attacks the problem of developing strategies for a firm to deal with technological change. We show that the product market strategies of the firm—including pricing, product positioning, and rent preemption strategies—can play a role in the efficient search for technology-related information when information search is costly and there are adaptation costs due to the presence of agency. We utilize a dynamic model of spatial competition with uncertain technological innovations in which firms can learn from each other about technological developments. Private information and agency conflicts are shown to increase the effective information search costs of incumbents, who then use interfirm learning to their advantage in equilibrium. This viewpoint also allows us to see the role of mergers and acquisitions, subsidiary formation, and internal R&D labs in a new light. The more general point is that organizational structures and, in particular, the differential distribution of information within the organization impose constraints on the information-search and adaptation strategies of the firm, and the formulation of product-market and R&D strategies serves to relax these constraints.     

Nonprofit boards: Size,performance and managerial incentives

We examine relations between board size, managerial incentives and enterprise performance in nonprofit organizations. We posit that a nonprofit's demand for directors increases in the number of programs it pursues, resulting in a positive association between program diversity and board size. Consequently, we predict that board size is inversely related to managerial pay-performance incentives and positively with overall organization performance. We find empirical evidence consistent with our hypotheses. The number of programs is positively related to board size. Board size is associated negatively with managerial incentives, positively with program spending and fundraising performance, and negatively with commercial revenue, in levels and changes.     

Equity market integration in the NAFTA region: Evidence from unit root and cointegration tests

This study examines integration of the three participating equity markets before and after the 1993 passage of NAFTA based on daily, weekly, and monthly data. As expected, unit root tests for the overall period 1988-2001 and the two subperiods, 1988-1993 (pre-NAFTA) and 1994-2001 (post-NAFTA), indicate that stock prices are non-stationary but stock returns are generally stationary for all three markets for all three periods. However, daily, weekly, and monthly equity prices in the three NAFTA countries are cointegrated only for the post-NAFTA period. Similarly, US stock prices are more integrated with both Canadian and Mexican stock prices after the passage of NAFTA. This evidence of increased financial integration and co-movement in NAFTA equity markets after the passage of NAFTA has important implications for policymakers and managers.     

Psychological barriers in gold prices?

This paper examines for the first time the existence of psychological barriers in a variety of daily and intra-day gold price series. This paper uses a number of statistical procedures and presents evidence of psychological barriers in gold prices. We document that prices in round numbers act as barriers with important effects on the conditional mean and variance of the gold price series around psychological barriers.     

Currency risk exposure of Chinese corporations

In spite of the rise of China and its currency, the currency risk of Chinese firms has not been studied adequately. In this paper we document for the first time that the stock returns of Chinese firms are significantly exposed to currency risks with many firms benefiting from the rise of the Yuan. Further, the magnitudes of the currency risk coefficients for Chinese companies (<10%) are smaller than those previously documented for other countries (20-40%). However, our results also indicate that Chinese export firms are exposed to significant risk related to the ASEAN currency index. Yuan appreciation also impacts exporters to India, Australia and Russia in some industries. The results documented in this study should be of much interest to managers, scholars, and policy-makers.     

Corporate fraud and investment distortions in efficient capital markets

Inefficient investment allocation induced by corporate fraud, where informed insiders strategically manipulate outside investors' beliefs, has been endemic historically and has recently attracted much attention. We reconcile corporate fraud and investment distortions with efficient capital markets, building on shareholder‐manager agency conflicts and investment renegotiation in active takeover markets. Because investments that are ex post inefficient are not renegotiation proof, the optimal renegotiation‐proof contract induces overstatements by managers, accompanied by overinvestment in low return states and underinvestment in high return states by rational investors. Our framework also helps explain why easy access to external capital appears to facilitate corporate fraud.     

Stabilization Activities by Underwriters after Initial Public Offerings

Prior research has assumed that underwriters post a stabilizing bid in the aftermarket. We find instead that aftermarket activities are less transparent and include stimulating demand through short covering and restricting supply by penalizing the flipping of shares. In more than half of IPOs, a short position of an average 10.75 percent of shares offered is covered in 22 transactions over 16.6 days in the aftermarket, resulting in a loss of 3.61 percent of underwriting fees. Underwriters manage price support activities by using a combination of aftermarket short covering, penalty bids, and the selective use of the overallotment option.     

Innovations in Retail Pricing and Promotions

Retailers confront a seemingly impossible dual competitive challenge: grow the top line while also preserving their bottom line. Innovations in pricing and promotion provide considerable opportunities to target customers effectively both offline and online. Retailers also have gained enhanced abilities to measure and improve the effectiveness of their promotions. This article synthesizes recent advances in pricing and promotions findings as they pertain to enhanced targeting, new price and promotion models, and improved effectiveness. It also highlights the role of new enabling technologies and suggests important avenues for further research.
