Trust is heritable, whereas distrust is not

Trust is heritable, whereas distrust is not. By Martin Reimann, Oliver Schilke & Karen Cook
Proceedings of the National Academy of Sciences, http://www.pnas.org/content/114/27/7007.abstract

Significance: Social scientists have devoted much attention to studying the sources and consequences of the disposition to trust but have only recently begun to investigate the disposition to distrust. An increasing consensus is emerging that distrust is not merely the opposite of trust. This article provides initial empirical evidence indicating that the sources of the dispositions to trust and distrust indeed do differ in important ways. Notably, although both trust and distrust are strongly influenced by the individual’s unique environment, interestingly, trust shows significant genetic influences, whereas distrust does not. Rather, distrust appears to be primarily socialized, including influences within the family. These findings provide new support for the bidimensionality of trust and distrust by demonstrating their distinct antecedents.

Abstract: Why do people distrust others in social exchange? To what degree, if at all, is distrust subject to genetic influences, and thus possibly heritable, and to what degree is it nurtured by families and immediate peers who encourage young people to be vigilant and suspicious of others? Answering these questions could provide fundamental clues about the sources of individual differences in the disposition to distrust, including how they may differ from the sources of individual differences in the disposition to trust. In this article, we report the results of a study of monozygotic and dizygotic female twins who were asked to decide either how much of a counterpart player's monetary endowment they wanted to take from their counterpart (i.e., distrust) or how much of their own monetary endowment they wanted to send to their counterpart (i.e., trust). Our results demonstrate that although the disposition to trust is explained to some extent by heritability but not by shared socialization, the disposition to distrust is explained by shared socialization but not by heritability. The sources of distrust are therefore distinct from the sources of trust in many ways.

Body-Weight and Women's Hours of Work: More Evidence that Marriage Markets Matter

Body-Weight and Women's Hours of Work: More Evidence that Marriage Markets Matter. By Shoshana Amyra Grossbard & Sankar Mukhopadhyay
San Diego State University Working Paper, May 2017, https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2979921

Abstract: Higher body-weight (BMI) can affect labor supply via its effects on outcomes in both labor markets and marriage markets. To the extent that it is associated with lower prospects of being in couple and obtaining intra-couple transfers, we expect that higher BMI will increase willingness to supply labor in labor markets, especially for women. We use US panel data from the NLSY79 and NLSY97 to examine whether body weight influences hours of work in the labor market. We use sibling BMI as an instrument for own BMI to address potential endogeneity of BMI in hours worked. We find that White women with higher BMI work more. This is true for both single and married White women. Results for other groups of women and men produce mixed results. The extended analysis suggests that what drives the relationship between BMI and hours worked is not lower market wages earned by high-BMI women, but rather lower spousal transfers to married women or lower expected intra-marriage transfers to single women.

Stimulus selectivity of drug purchase tasks: A preliminary study evaluating alcohol and cigarette demand

Stimulus selectivity of drug purchase tasks: A preliminary study evaluating alcohol and cigarette demand. By Strickland, Justin C.; Stoops, William W. Experimental and Clinical Psychopharmacology, Vol 25(3), Jun 2017, 198-207. http://dx.doi.org/10.1037/pha0000123

Abstract: The use of drug purchase tasks to measure drug demand in human behavioral pharmacology and addiction research has proliferated in recent years. Few studies have systematically evaluated the stimulus selectivity of drug purchase tasks to demonstrate that demand metrics are specific to valuation of or demand for the commodity under study. Stimulus selectivity is broadly defined for this purpose as a condition under which a specific stimulus input or target (e.g., alcohol, cigarettes) is the primary determinant of behavior (e.g., demand). The overall goal of the present study was to evaluate the stimulus selectivity of drug purchase tasks. Participants were sampled from the Amazon.com’s crowdsourcing platform Mechanical Turk. Participants completed either alcohol and soda purchase tasks (Experiment 1; N = 139) or cigarette and chocolate purchase tasks (Experiment 2; N = 46), and demand metrics were compared to self-reported use behaviors. Demand metrics for alcohol and soda were closely associated with commodity-similar (e.g., alcohol demand and weekly alcohol use) but not commodity-different (e.g., alcohol demand and weekly soda use) variables. A similar pattern was observed for cigarette and chocolate demand, but selectivity was not as consistent as for alcohol and soda. Collectively, we observed robust selectivity for alcohol and soda purchase tasks and modest selectivity for cigarette and chocolate purchase tasks. These preliminary outcomes suggest that demand metrics adequately reflect the specific commodity under study and support the continued use of purchase tasks in substance use research

Using Appellate Decisions to Evaluate the Impact of Judicial Elections

Using Appellate Decisions to Evaluate the Impact of Judicial Elections. By Gregory DeAngelo & Bryan McCannon
West Virginia University Working Paper, June 2017, https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2973369

Abstract: We investigate judicial election's impact on criminal case handling. Data from appeals of felony convictions in New York state are used to measure the accuracy of lower court outcomes. We also account for judicial election pressures and career paths. A theoretical model is developed where to guide the empirical analysis judges face a trade-off between exerting time and effort in criminal and civil cases. We show that during a re-election campaign, when the importance of good decision making in both types of cases is heightened, if the civil case outcomes are sufficiently more important, then error rates in criminal cases can increase. This effect is reversed for those who have a greater intrinsic interest in criminal justice. Results from the empirical analysis conform to the hypotheses derived from the theoretical model. Convictions that occur during the judge's re-election campaign are less likely to be upheld if appealed. The effect is concentrated in those who did not previously work in a prosecutor's office. In fact, judges who are former prosecutors experience higher affirmation rates with an additional escalation in success when up for re-election. We also differentiate judges who handle more civil cases and show that re-election distortions are greater. Finally, we also consider those who receive greater campaign support from special interest groups. Those who receive financial support have reduced accuracy. These additional results are consistent with the theory that it is the trade-off between criminal and civil cases that is driving decision making. Our results suggest that the criminal justice system is impacted by the interaction between a judge's characteristics and re-election incentives.

Effects of alcohol, initial gambling outcomes, impulsivity, and gambling cognitions on gambling behavior using a video poker task

Effects of alcohol, initial gambling outcomes, impulsivity, and gambling cognitions on gambling behavior using a video poker task. By Corbin, William R.; Cronce, Jessica M.
Experimental and Clinical Psychopharmacology, Vol 25(3), Jun 2017, 175-185. http://dx.doi.org/10.1037/pha0000125

Abstract: Drinking and gambling frequently co-occur, and concurrent gambling and drinking may lead to greater negative consequences than either behavior alone. Building on prior research on the effects of alcohol, initial gambling outcomes, impulsivity, and gambling cognitions on gambling behaviors using a chance-based (nonstrategic) slot-machine task, the current study explored the impact of these factors on a skill-based (strategic) video poker task. We anticipated larger average bets and greater gambling persistence under alcohol relative to placebo, and expected alcohol effects to be moderated by initial gambling outcomes, impulsivity, and gambling cognitions. Participants (N = 162; 25.9% female) were randomly assigned to alcohol (target BrAC = .08g%) or placebo and were given $10 to wager on a simulated video poker task, which was programmed to produce 1 of 3 initial outcomes (win, breakeven, or lose) before beginning a progressive loss schedule. Despite evidence for validity of the video poker task and alcohol administration paradigm, primary hypotheses were not supported. Individuals who received alcohol placed smaller wagers than participants in the placebo condition, though this effect was not statistically significant, and the direction of effects was reversed in at-risk gamblers (n = 41). These findings contradict prior research and suggest that alcohol effects on gambling behavior may differ by gambling type (nonstrategic vs. strategic games). Interventions that suggest alcohol is universally disinhibiting may be at odds with young adults’ lived experience and thus be less effective than those that recognize the greater complexity of alcohol effects.

Far from fairness: Prejudice, skin color, and psychological functioning in Asian Americans

Far from fairness: Prejudice, skin color, and psychological functioning in Asian Americans. By Tran, Alisia G. T. T.; Cheng, Hsiu-Lan; Netland, Jason D.; Miyake, Elisa R.
Cultural Diversity and Ethnic Minority Psychology, Vol 23(3), Jul 2017, 407-415.
http://dx.doi.org/10.1037/cdp0000128

Abstract

Objectives: We explored the moderating role of observed skin color in the association between prejudice and concurrent and lagged psychological functioning (i.e., depression, ingroup/outgroup psychological connectedness). We further aimed to understand gender differences in these processes.

Method: Data from 821 Asian American undergraduate students (57.5% female and 42.5% male) were drawn from the National Longitudinal Survey of Freshman. Cross-sectional and longitudinal regression-based moderation models were conducted with PROCESS 2.13 for SPSS.

Results: Lighter skin color nullified the association between prejudice and recent depression for Asian American females. This moderating effect did not hold over time with regards to depression symptoms 1 year later. Additionally, prejudice predicted psychological distance to other Asian students 1 year later among females rated as lighter in skin color, whereas prejudice was tied to psychological closeness for females with darker skin ratings.

Conclusions: Results highlight skin color as a pertinent factor relevant to the short-term and long-term mental health and social experiences of Asian American women in particular.

County governing boards: Where are all the women?

County governing boards: Where are all the women? By Leander Kellogg et al.
Politics, Groups, and Identities, http://www.tandfonline.com/doi/abs/10.1080/21565503.2017.1304223?journalCode=rpgi20

Abstract: This research seeks to explore the extent of women representation on county governing boards and tests several hypotheses to explain variation in representation. This study evaluates a random sample of 394 of the more than 3000 counties in the United States. Half of the counties did not have any women serving on their county governing boards. A two-stage analysis using first a logit model sought to explain when counties have women commissioners and then a truncated regression analysis evaluated the percentage of women serving on county boards. Size of governing boards, size of government, religious adherence, and two election formats had significant effects in explaining when a county had women commissioners. Three variables (religious adherence, level of support for President Obama, and size of governing boards) were significant in explaining the percentage of women serving on county governing boards with size of the boards operating opposite of the hypothesized direction.

Does the Stock Market Boost Firm Innovation? Evidence from Chinese Firms

Does the Stock Market Boost Firm Innovation? Evidence from Chinese Firms. By Hui He, Hanya Li, Jinfan Zhang. IMF Working Paper No. 17/147, http://www.imf.org/en/Publications/WP/Issues/2017/06/29/Does-the-Stock-Market-Boost-Firm-Innovation-Evidence-from-Chinese-Firms-44983?cid=em-COM-123-35527

Summary: The paper analyses the effect of the stock market on firm innovation through the lens of initial public offering (IPO) using uniquely matched Chinese firm-level data. We find that IPOs lead to an increase in both the quantity and quality of firm innovation activity. In addition, IPOs expand a firm’s scope of innovation beyond its core business. The impact of IPOs on firm innovation varies across financial constraints, corporate governance, and ownership structures. Our results further illustrate that IPOs induce a firm to increase the number of inventors and enable better retention of existing inventors after the IPO. Finally, we show that the enhanced innovation activity resulting from IPOs increases a firm’s Tobin’s Q in the long run.

More politicians, more corruption: Evidence from Swedish municipalities

More politicians, more corruption: Evidence from Swedish municipalities. By Andreas Bergh, Günther Fink & Richard Öhrvall. Public Choice (2017), https://link.springer.com/article/10.1007/s11127-017-0458-4

Abstract: In the literature on political economy and public choice, it is typically assumed that government size correlates positively with public corruption. The empirical literature, however, is inconclusive, owing to both measurement problems and endogeneity. This paper creates a corruption index based on original data from a survey covering top politicians and civil servants in all Swedish municipalities. The effect of more politicians on corruption problems is analyzed using discontinuities in the required minimum size of local councils. Despite the fact that Sweden consistently has been ranked among the least corrupt countries in the world, the survey suggest that non-trivial corruption problems are present in Sweden. Municipalities with more local council seats have more reported corruption problems, and the regression discontinuity design suggests that the effect is causal.
