After watching a colleague struggle with the care of his mother when she was affected by fecal incontinence, the Consure Medical team began investigating this problem as a potential need to address. They completed an extensive needs finding…

We raise four sets of issues relating to the definition and measurement of first mover advantage. We begin by posing questions about the basic definition of FMA and whether advantage should be measured in terms of profit, market share or…

We study a dynamic market with asymmetric information that creates the lemons problem. We compare efficiency of the market under different assumptions about the timing of trade. We identify positive and negative aspects of dynamic trading,…

To help address the issue of unplanned pregnancy and maternal mortality in the developing world, researchers at the University of Georgetown’s Institute for Reproductive Health (IRH) recognized the need for an intuitive, natural contraception…

Dropout and other feature noising schemes control overfitting by artificially corrupting the training data. For generalized linear models, dropout performs a form of adaptive regularization. Using this viewpoint, we show that the dropout…

An accounting-based earnings manipulation detection model has strong out-of-sample power to predict cross-sectional returns. Companies with a higher probability of manipulation (M-score) earn lower returns on every decile portfolio sorted by size…

This chapter describes the mechanisms through which the experience of processing ease, or fluency, can influence attitudes and persuasion. In particular, we argue that ease can impact attitude change not only by serving as a peripheral cue (e.g…

Because employment is simultaneously an economic and a social relationship, one cannot profitably study it as one or the other in isolation. To understand employment relationships requires taking into account both economic and social-…

This paper aims to understand the impact of temporal spacing between ad exposures on the likelihood of a consumer purchasing the advertised product. I create an individual-level data set with exogenous variation in the spacing and intensity of…

Game theory is the natural tool when analyzing the strategic use of natural resources. This article presents a sequence of related simple two-stage games to illustrate a range of problems, generating a large number of lessons. It explores…

This article develops a new family of Gaussian macro-dynamic term structure models (MTSMs) in which bond yields follow a low-dimensional factor structure and the historical distribution of bond yields and macroeconomic variables is…

Random graph generation is an important tool for studying large complex networks and recently has been extensively used by biologists, computer scientists, economists, electrical engineers, and mathematical sociologists. Despite many remarkable…

Across six field and laboratory experiments, participants given a concretely-framed prosocial goal (e.g., making someone smile, increasing recycling) felt happier after performing a goal-directed act of kindness than did those who were assigned a…

In this article, we outline a model of how organizations can effectively shape employees’ affective reactions to failure. We do not suggest that organizations eliminate the experience of negative affect following performance failures—instead, we…

People tend to lack the self-control to undergo an unpleasant service that would generate future benefits. This paper derives a tractable quasi-hyperbolic discounting model of that behavioral tendency (for a queueing system in which service time…

Globally, pneumonia kills more children than any other illness. In developed countries, pneumonia and other acute respiratory conditions are treated via mechanical ventilators. In resource-constrained settings, however, ventilators are often not…

 Using an earnings management model in which managers manipulate information when the firm s control system fails, I introduce a measure of earnings quality ; based on the notion of integral precision, that has solid theoretical foundations…
