Malleable Conjoint Partworths: How the Breadth of Response Scales Alters Price Sensitivity

Format
Journal Article
Journal
Journal of Consumer Psychology

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.

Managerial Decision Making in Customer Management: Adaptive, Fast and Frugal?

Journal of the Academy of Marketing Science

While customer management has become a top priority for practitioners and academics, little is known about how managers actually make customer management decisions. Our study addresses this gap and uses the adaptive decision maker as well as the fast and frugal heuristics frameworks to gain a better understanding of managerial decision making. Using the process-tracing tool MouselabWEB, we presented sales managers in retail banking with three typical customer management prediction tasks.

Pre-Disclosure Accumulations by Activist Investors: Evidence and Policy

The Journal of Corporation Law

The SEC is currently considering a rulemaking petition requesting that the Commission shorten the ten-day window, established by Section 13(d) of the Williams Act, within which investors must publicly disclose purchases of a 5% or greater stake in public companies. In this Article, we provide the first systematic empirical evidence on these disclosures and find that several of the petition's factual premises are not consistent with the evidence.

Investment, Liquidity, and Financing under Uncertainty

Working Paper

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.

Liability-Driven Investment with Downside Risk

Authors
Bingxu Chen and M. Suresh Sundaresan
Date

Format
Journal Article
Journal
Journal of Portfolio Management

We develop a liability driven investment framework that incorporates downside risk penalties for not meeting liabilities. The shortfall between the asset and liabilities can be valued as an option which swaps the value of the endogenously determined optimal portfolio for the value of the liabilities. The optimal portfolio selection exhibits endogenous risk aversion and as the funding ratio deviates from the fully funded case in both directions, effective risk aversion decreases.

Does Time Fly When You're Counting Down? The Effect of Counting Direction on Subjective Time Judgments

Authors

Format
Journal Article
Journal
Journal of Consumer Psychology

We show that counting downward while performing a task shortens the perceived duration of the task compared to counting upward. People perceive that less time has elapsed when they were counting downward versus upward while using a product (Studies 1 and 3) or watching geometrical shapes (Study 2). The counting direction effect is obtained using both prospective and retrospective time judgments (Study 3), but only when the count range begins with the number “1” (Study 2).

Dynamic agency and the <i>q</i> theory of investment

Authors
Peter DeMarzo, Mike Fishman, Zhiguo He, and Neng Wang
Date
December 1, 2012
Format
Journal Article
Journal
Journal of Finance

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.

Industry Self-Regulation as a Solution of Reputation Commons: A Case of the Commercial Bank Clearinghouse

Authors
Lori Yue and Paul Ingram
Date

Format
Chapter
Book
Oxford Handbook of Reputation Commons

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.
