Value versus Glamour

The fragility of the CAPM has led to a resurgence of research that frequently uses trading strategies based on sorting procedures to uncover relations between firm characteristics (such as “value” or “glamour”) and equity returns. We examine the propensity of these strategies to generate statistically and economically significant profits due to our familiarity with the data. Under plausible assumptions, data snooping can account for up to 50 percent of the in‐sample relations between firm characteristics and returns uncovered using single (one‐way) sorts. The biases can be much larger if we simultaneously condition returns on two (or more) characteristics.     

Technological acquisitions and the innovation performance of acquiring firms: a longitudinal study

This paper examines the impact of acquisitions on the subsequent innovation performance of acquiring firms in the chemicals industry. We distinguish between technological acquisitions, acquisitions in which technology is a component of the acquired firm's assets, and nontechnological acquisitions: acquisitions that do not involve a technological component. We develop a framework relating acquisitions to firm innovation performance and develop a set of measures for quantifying the technological inputs a firm obtains through acquisitions. We find that within technological acquisitions absolute size of the acquired knowledge base enhances innovation performance, while relative size of the acquired knowledge base reduces innovation output. The relatedness of acquired and acquiring knowledge bases has a nonlinear impact on innovation output. Nontechnological acquisitions do not have a significant effect on subsequent innovation output.

Quantifying equilibrium network externalities in the ACH banking industry

We seek to determine the causes and magnitudes of network externalities for the automated clearing house (ACH) electronic payments system. We construct an equilibrium model of customer and bank adoption of ACH. We structurally estimate the parameters of the model using an indirect inference procedure and panel data. The parameters are identified from exogenous variation in the adoption decisions of banks based outside the network and other factors. We find that most of the impediment to ACH adoption is from large customer fixed costs of adoption. Policies to provide moderate subsidies to customers and larger subsidies to banks for ACH adoption could increase welfare significantly.     

Cost of hospital care for elderly at risk of falling

The variables that relate to cost of hospital care for a large sample of elderly patients at risk for falling are examined. The chief predictors of cost of hospitalization were medical, pharmacy, and nursing interventions. Use of nursing interventions, on average, raised the median hospital cost less than use of medical or pharmacy interventions. Using a standardized nursing language with the hospital's information system can provide nurses with information that demonstrates the cost effectiveness of their interventions.     

Mean-Reversion in REITs Discount to NAV &; Risk Premium

REITs discount to NAV is a puzzling regularity. The sharp increase in volatility of REITs prices over the past few years has spurred a relatively new concern amongst academics, managers and investors about the consequences of, and causes of, property risk premium on discount to NAV. The two interrelated questions arising from the recent increase in volatility of REITs prices are: Is the increased volatility responsible for the observed widening in discount to NAV? What does the observed private and public risk premium tell us about discount to NAV? We attempt to address these questions by analysing risk premiums in private and public real estate markets. The analysis is conducted in the most recent years of high stock price volatility. Our analysis reveals two major results: a tendency for discount to NAV to revert to the long term mean value of 20% and, more significantly, a lower risk premium in equivalent yields in private market than in public market. These results suggest that investors in public market have a different conception of property risk and complexity of lease options than what is conveyed by private property valuation.     

Keeping up with the Vaishyas? Caste and relative standing in India

People care about relative, and not only absolute, income. Thispaper investigates the importance of relative income withinand between castes in the Indian caste system, using a choiceexperimental approach. The results indicate that slightly morethan half of the marginal utility of income comes from somekind of relative income effects, on average. This is comparableto the results from previous studies in other countries. Belongingto a low caste and having a low family income are associatedwith higher concern for relative income. Moreover, an increasein the mean income of the caste to which the individual belongs,everything else held constant, reduces utility for the individual.Thus, the negative welfare effect of having a reduced relativeincome compared to the own caste average income dominates thepositive welfare effect due to increased relative income ofthe own caste compared to the income of other castes.     

Technology transfer, licensing and the speed of endogenous technological change

As licensing contracts usually require the licensee firm to purchase tied inputs from the seller of the technology, the licensee firm has an incentive to embark on an R&D program for development of substitutes for the tied inputs. This paper characterizes the licensee firm's optimal speed of R&D and the optimal expected date of switch-over to the substitute inputs in an infinite-horizon model under uncertainty about the timing of success of the R&D program. The effects of different government subsidies or taxes, changes in input prices and other parameters on the optimal speed of R&D and on the expected date of switchover to the substitute are also investigated. It is also shown that strategic behavior by the seller of the technology may delay the development of the substitute by the licensee firm.     

The Migration of Young Adults from Non-Metropolitan Counties

This article examines young adult migration from non-metropolitan counties to either different non-metropolitan counties or to metropolitan areas. The results show that expected gains in initial earnings provide young entrants to the labor force with a marked incentive to migrate from their non-metropolitan counties of origin. Initial earnings gains stem, in part, from higher returns to schooling in both metropolitan areas and other non-metropolitan counties. The propensity to migrate is also sensitive to the costs of migration, which, in turn, are correlated with paternal education and the local presence of extended family.     

Asset Maturity, Debt Covenants, and Debt Maturity Choice

The existing research on debt‐maturity under asymmetric information has focused on the impact of differential information regarding asset quality on the debt maturity decision. This research has generally indicated the optimality of short‐term debt financing as a vehicle of mitigating the adverse selection problem. In this paper, I consider the impact of information asymmetry regarding the maturity structure of cash flows on the debt maturity decision. In this context, long‐term debt is generally the form of debt financing most effective in alleviating the adverse selection problem. I also show that costs of adverse selection may induce some mismatching of debt maturity and asset maturity in the presence of significant transaction costs.
