Experimental Tests of Self-Selection and Screening in Insurance Decisions

A major characteristic of insurance markets is information asymmetry that may lead to phenomena such as adverse selection and moral hazard. Another aspect of markets with asymmetric information is self-selection, which refers to the pattern of choices that individuals with different personal characteristics make when facing a menu of contracts or options. To combat problems of asymmetric information, insurance firms can use screening. That is, they can offer the clients a menu of choices and infer their characteristics from their choices.This article reports the results of several studies that examined the degree to which people behave according to the notions of self-selection and screening. Subjects played the role of either insurance buyers or sellers. The results of these studies provide partial support for the hypothesis that subjects use self-selection and screening in insurance markets. Our study also points at the importance of learning in experimental studies. In one-stage experiments where subjects did not get feedback, screening was not detected. When multistage experiments were conducted, and the subjects learned from experience and were also taught the relevant theories, their decisions were more aligned with screening.     

Pathways from discovery to commercialisation: using web sources to track small and medium-sized enterprise strategies in emerging nanotechnologies

This paper presents results from a pilot study of small and medium-sized enterprises (SMEs) based on a web-scraping and content analysis of current and archived nanotechnology enterprise websites. We use this approach to explore nanotechnology SMEs transitions from discovery to commercialisation and understand how transitions vary by SME characteristics, technology and market sectors. Our findings suggest that although the idealised linear innovation model is present, important instances of divergence exist. Cluster analysis uncovered sectoral differences but even more distinctions based on the age, funding source, and research intensity.     

Entering new markets: The effect of performance feedback near aspiration and well below and above it

Research summary : This study draws on the resource‐based view and the behavioral theory of the firm to gain new insights about the effect of performance relative to aspiration level (i.e., performance feedback) on the decision to enter new markets. Results show an inverted U‐shaped relationship between performance both below and above aspiration level, and the probability of firms to enter new markets. That is, when firms are well below or well above their aspiration level, they significantly change their behavior. This article develops a theoretical framework to clarify and organize these findings. Managerial summary : This study examines the effect of performance feedback, and particularly, large discrepancies between firm performance and aspiration level on the decision to enter new markets. It provides support to the role of performance feedback in affecting the decision to enter new markets, a factor that has received relatively little attention in the extensive literature that has examined the inducements of such moves. Results show that, as performance falls below or rises above aspiration, a firm's probability of entering new markets increases up to a certain point after which this relationship decreases. This shows that the tendency to enter new markets is different for firms that are in the neighborhood of aspiration level compared to those that are well below or above it.

COMPETITIVENESS AND STRESS

This study explores the relationship between competitiveness and stress. In Experiment 1, we observe a higher response of cortisol—the primary stress hormone—to the computation task coupled with tournament than to the computation task with piece rate. Moreover, more competitive subjects exhibit higher stress responses than their less competitive counterparts in the computation tasks under both tournament and piece rate. In Experiment 2, we find that exogenously induced stress does not significantly affect competitiveness. Overall, our findings reveal an important trade‐off between tournament and piece rate in terms of stress response with implications on the design of incentive contracts.     

Building an Entrepreneurial Economy: The Case of Korea 1998–2005

Abstract

This paper examines how entrepreneurship takes place in an economy where traditional structural settings are not favorable to entrepreneurial activities. Specifically, it investigates the case of Korea during 1998–2005, when the national economy experienced fairly dramatic upsurge of start-ups and related changes. The paper argues that a national economy may achieve significant structural changes when diverse conditions are in place, including not only intentional efforts, e.g. governmental policies, but factors of serendipity triggering potential disruption to the economy, e.g. an external shock such as the Asian financial crisis in 1997. During the observation period, Korea went through notable changes in terms of entrepreneurship. Although limited, the Korean economy looks at possibilities of having small and medium-sized companies co-evolve with large ones such as chaebols.     

HOW BELIEFS ABOUT HIV STATUS AFFECT RISKY BEHAVIORS: EVIDENCE FROM MALAWI

This paper examines how beliefs about own HIV status affect decisions to engage in risky sexual behavior, as measured by having extramarital sex and/or multiple sex partners. The empirical analysis is based on a panel survey of males from the 2006 and 2008 rounds of the Malawi Diffusion and Ideational Change Project (MDICP). The paper develops a behavioral model of the belief‐risky behavior relationship and estimates the causal effect of beliefs on risky behavior using the Arellano and Carrasco (2003) semiparametric panel data estimator, which accommodates both unobserved heterogeneity and belief endogeneity arising from a possible dependence of current beliefs on past risky behavior. Results show that downward revisions in the belief assigned to being HIV positive increase risky behavior and upward revisions decrease it. For example, based on a linear specification, a decrease in the perceived probability of being HIV positive from 10 to 0 percentage points increases the probability of engaging in risky behavior (extramarital affairs) from 8.3 to 14.1 percentage points. We also develop and implement a modified version of the Arellano and Carrasco (2003) estimator to allow for misreporting of risky behavior and find estimates to be robust to a range of plausible misreporting levels. © 2013 The Authors.

Confounding changes in averages with marginal effects: How anchoring can destroy economic value in strategic investment assessments

Profit maximization requires that decision makers assess marginal profits. We demonstrate that decision makers often confound marginal profits with changes in average profits (e.g., changes in return‐on‐investment). This results in systematic deviations from profit maximization where decision makers forgo profit‐enhancing investments that reduce average profits or engage in loss‐enhancing investments that decrease average losses. In other words, average profit becomes an anchor by which new investments are assessed. We conduct two decision‐making experiments that show this bias and demonstrate it is pronounced when average profit data are accessible or task‐relevant. Moreover, we find within‐subject effects across experiments, which helps demonstrate the mechanism that invokes the bias. Copyright © 2013 John Wiley & Sons, Ltd.     

Here it comes: defined contribution health care

The Patient Protection and Affordable Care Act includes provisions to make the individual health insurance marketplace one where all Americans, including those with preexisting health conditions, can obtain affordable coverage. At the same time, the act has failed to address, in any significant way, many of the underlying flaws in the current U.S. health care system that have caused costs to spiral out of control. The combination of persistent U.S. health care cost increases and a viable individual health insurance marketplace will cause a sea change in employer-sponsored health care offerings that is similar to that seen among employer-sponsored retirement benefit plans: movement away from defined benefit approaches and toward defined contribution designs. Although the authors show parallels between the evolution of employers' health care and retirement offerings, they explain why certain key developments will need to occur before defined contribution approaches become as prevalent in employer-sponsored health care plans as they are in today's employer-sponsored retirement plans.
