Using data from a major mortgage bank, we examine the predictive power of mortgage delinquency models as an aggregate measure of the quality of information recorded at loan origination. We measure model predictive power using an out-of-sample prediction criterion and compare predictive power of delinquency models over time and across loans of different documentation levels and origination channels.
In one laboratory study and one field study conducted with a large, representative sample of respondents, we show that seemingly innocuous questions that precede a conjoint task, such as demographic and usage-related screening questions can alter the price sensitivities recovered from the main conjoint task. The findings demonstrate that whether these prior questions use broad response categories (i.e., few scale points) or narrow response categories (i.e., many scale points) systematically influences consumers' price sensitivity in a CBC (Choice Based Conjoint) study.
This paper considers a model of (irreversible) investment under uncertainty for a firm facing external financing costs. Such a firm prefers to fund its investment through internal funds, so that thefirm's optimal investment policy and value now depend on the size of its retained earnings. We show that the standard real options results are significantly modified when there are external financing costs.
We develop an analytically-tractable model integrating the dynamic theory of investment with dynamic optimal incentive contracting, thereby endogenizing financing constraints. Incentive contracting generates a history-dependent wedge between marginal and average q, and both vary over time as good (bad) performance relaxes (tightens) financing constraints. Financial slack, not cash flow, is the appropriate proxy for financing constraints.
The performance of organizations depends partly on the reputations of their industries. Such reputations are “intangible commons.” Interest in protecting mutual welfare motivates members of an industry to engage in self-regulation. However, the current literature tends to have a pessimistic view of the efficacy of self-regulation in solving the problem of reputational commons. We argue that the obstacles forecasted by such pessimistic reasoning are context-bound and can be overcome if industry self-regulation includes effective sanctions and exclusion strategies.
The modal scientific approach in consumer research is to deduce hypotheses from existing theory about relationships between theoretic constructs, test those relationships experimentally, and then show “process” evidence via moderation and mediation. This approach has its advantages, but other styles of research also have much to offer. We distinguish among alternative research styles in terms of their philosophical orientation (theory-driven vs. phenomenon-driven) and their intended contribution (understanding a substantive phenomenon vs. building or expanding theory).
In this report, the authors quantify the strategic relationship between brand management (brand equity) and customer management (the components of CLV), and demonstrate the role that marketing activities play in this relationship. They examine a unique database from the U.S. automobile market, comprised of 10 years of survey-based brand equity measures as well as acquisition rates, retention rates, and customer profitability.
This paper extends the contextual perspective of network evolution to account for a more complete process of network evolution by showing that the impacts of fads and fashions on the formation and dissolution of interorganizational networks are asymmetric. Building on contact theory, this paper proposes that direct contact affords a flow of knowledge that counters tendencies to social conformity. Network dissolution differs from network formation in that partners have already obtained direct information.
