The Federal Student Loan Program: Quantitative implications for college enrollment and default rates

I quantify the effects of alternative student loan policies on college enrollment, borrowing behavior, and default rates in a heterogeneous model of life-cycle earnings and human capital accumulation. I find that the combination of learning ability and initial stock of human capital drives the decision to enroll in college, while parental wealth has minimal effects on enrollment. Repayment flexibility increases enrollment significantly, whereas relaxation of eligibility requirements has little effect on enrollment or default rates. The former policy benefits low-income households, while the latter has negligible effects on these households.     

Development and validation of a firm-level vertical and horizontal internationalization metric

The lack of valid and reliable measures of firm-level vertical and horizontal internationalization is impeding the development and testing of hypothesized relationships between these respective dimensions of internationalization and a range of important MNE characteristics, actions, and effects. Through a series of qualitative and quantitative studies using data collected from senior MNE executives (total N?=?3,146), we develop and validate a scale to measure both vertical and horizontal firm-level internationalization. Subscales for each type of internationalization prove to be unidimensional, reliable, temporally stable, and to have predictive, cross-cultural, cross-sectoral, and discriminant validity.     

Risk and Return: A Revisit Using Expected Returns

This paper uses direct estimates of expected returns to examine the link between standard measures of financial risk and investor return requirements. The results show that systematic risk commands a significant positive risk premium, much larger than found using historical returns as proxies for expectations. Furthermore, there are nonlinearities in the relationship between risk and return. Finally, we show that expected returns and risk premiums in the equity markets change over time and that these changes are related to changes in interest rates on U.S. government obligations.     

Does sustainable intensification of maize production enhance child nutrition? Evidence from rural Tanzania

Food insecurity, child malnutrition, and land degradation remain persistent problems in sub‐Saharan Africa. Agricultural sustainable intensification (SI) has been proposed as a possible solution to simultaneously address these challenges. Yet there is little empirical evidence on if agricultural management practices and inputs that contribute to SI from an environmental standpoint do indeed improve food security or child nutrition. We use three waves of data from the nationally‐representative Tanzania National Panel Survey to analyze the child nutrition effects of rural households’ adoption of farming practices that can contribute to the SI of maize production. We group households into four categories based on their use of three soil fertility management practices on their maize plots: “Nonadoption”; “Intensification” (use of inorganic fertilizer only); “Sustainable” (use of organic fertilizer, maize–legume intercropping, or both); and “SI” (joint use of inorganic fertilizer with organic fertilizer and/or maize–legume intercropping). The results from multinomial endogenous treatment effects models with the Mundlak–Chamberlain device suggest that use of practices in the “SI” category is associated with improvements in children's height‐for‐age and weight‐for‐age z‐scores relative to “Nonadoption,” particularly for children aged 25–59 months. These effects appear to come through improvements in both crop income and productivity.     

Delivering a superior customer experience in solutions delivery processes: Seven factors for success

In marketing complex solutions to customers, business-to-business firms face significant challenges in managing the customer experience effectively in solutions delivery processes—due primarily to the use of ad hoc teams. To learn more about these challenges, we interviewed executives from a Fortune 100 high-technology company. We identify seven factors ad hoc teams can employ to address this problem, focusing on delivery team composition, delivery processes, and organization-level changes that can be made to optimize the success of the team. In solutions selling, the delivery phase is particularly critical to success. The factors identified enable firms to better manage the customer experience and enhance performance.     

Differences in Information and Common Stock Returns: Estimation Risk or Unequal Distribution of Information?

Information can be differential or “incomplete” in two different ways: as a result of the quality of information itself or as a result of the manner in which information is distributed to investors. The effect on capital market equilibrium under either scenario is that higher returns will be required for low information securities. Prior empirical studies documenting a relationship between low information firms and positive abnormal returns have generally attributed such results to the quality of information; the current research tests the possibility that these results are instead due to the manner in which information is distributed to investors.
