Explaining the decline of the US saving rate: The role of health expenditure. Yi Chen, Maurizio Mazzocco, Béla Személy. International Economic Review, April 17 2019. https://doi.org/10.1111/iere.12405
Abstract: The U.S. saving rate declined by 8 percent between 1980 and 2009. We document that the decline can be explained by rising health expenditures. Using exogenous variation in medical expenses generated by FDA drug approvals, we document that a 1 percentage point increase in health expenditure generated a decline in saving rate of 0.9 percentage points. We then estimate a model of household decisions to evaluate the mechanisms behind the decline. We find that the rise in health expenses and drop in saving rate are driven by progress in health technology, reduction in co‐payment rates, and improvements in income processes.

Greater exposure to “high-achieving” boys decreases the likelihood that girls go on to complete a bachelor's degree, affects negatively their math & science grades, decreases labor force participation
Girls, Boys, and High Achievers. Angela Cools, Raquel Fernández, Eleonora Patacchini.
NBER Working Paper No. 25763, April 2019. https://www.nber.org/papers/w25763
Abstract: This paper studies the effect of exposure to female and male “high-achievers” in high school on the long-run educational outcomes of their peers. Using data from a recent cohort of students in the United States, we identify a causal effect by exploiting quasi-random variation in the exposure of students to peers with highly educated parents across cohorts within a school. We find that greater exposure to “high-achieving” boys, as proxied by their parents' education, decreases the likelihood that girls go on to complete a bachelor's degree, substituting the latter with junior college degrees. It also affects negatively their math and science grades and, in the long term, decreases labor force participation and increases fertility. We explore possible mechanisms and find that greater exposure leads to lower self-confidence and aspirations and to more risky behavior (including having a child before age 18). The girls most strongly affected are those in the bottom half of the ability distribution (as measured by the Peabody Picture Vocabulary Test), those with at least one college-educated parent, and those attending a school in the upper half of the socioeconomic distribution. The effects are quantitatively important: an increase of one standard deviation in the percent of “high-achieving” boys decreases the probability of obtaining a bachelor's degree from 2.2-4.5 percentage points, depending on the group. Greater exposure to “high-achieving” girls, on the other hand, increases bachelor's degree attainment for girls in the lower half of the ability distribution, those without a college-educated parent, and those attending a school in the upper half of the socio-economic distribution. The effect of “high-achievers” on male outcomes is markedly different: boys are unaffected by “high-achievers” of either gender.

Homosexual orientation is associated with higher odds of erectile dysfunction and lower odds of premature ejaculation compared with heterosexual orientation
Barbonetti A, D’Andrea S, Cavallo F, et al. Erectile Dysfunction and Premature Ejaculation in Homosexual and Heterosexual Men: A Systematic Review and Meta-Analysis of Comparative Studies. J Sex Med 2019;16:624–632. https://doi.org/10.1016/j.jsxm.2019.02.014
Abstract
Introduction: Comparative studies on differences in sexual function outcomes between homosexual and heterosexual men are sparse and inconclusive.
Aim: To systematically evaluate whether, and to what extent, a statistically significant difference exists in the odds of erectile dysfunction (ED) and premature ejaculation (PE) between homosexual and heterosexual men.
Methods: A thorough search of Medline, SCOPUS, CINAHL, and Web of Science databases was carried out to identify case-control studies comparing the prevalence of ED and PE in homosexual and heterosexual men. Methodological quality of the included studies was assessed using the Newcastle-Ottawa Scale. Odds ratios (ORs) of reporting ED and PE were combined using random effect models. The Cochrane Q and I2 tests were carried out to analyze the between-studies heterogeneity. Funnel plots and trim-and-fill analysis were used to assess publication bias.
Main Outcome Measures: The relationship between sexual orientation and odds of ED and PE was assessed by calculating pooled ORs with a 95% CI.
Results: 4 studies included in the quantitative analysis collectively provided information on 1,807 homosexual and 4,055 heterosexual men. The pooled ORs indicated that homosexual orientation was associated with 1.5-fold higher odds of reporting ED (OR = 1.49, 95% CI = 1.03–2.16; P = .04) and 28.0% lower odds of reporting PE in comparison to the heterosexual orientation (OR = 0.72, 95% CI = 0.52–1.00; P = .05). However, a significant heterogeneity among the studies was observed. Funnel plots revealed a possible publication bias only for the ED analysis, where the trim-and-fill test detected a putative missing study. Nevertheless, even when the pooled estimate was adjusted for publication bias, there was a significantly higher risk of ED in the homosexual group (adjusted OR = 1.60, 95% CI = 1.10–2.30; P = .01).
Clinical Implications: These findings can drive future studies on sexual needs and concerns of homosexual men, which might not exactly match those of heterosexual individuals.
Strength & Limitations: This is the first meta-analysis exploring the differences in the prevalence of ED and PE between homosexual and heterosexual men. However, the results should be interpreted with caution, because their generalization could be hindered by the non-probabilistic nature of the samples, and a measurement bias could result from the use of different non-standardized indicators of sexual dysfunctions.
Conclusion: Homosexual orientation is associated with higher odds of ED and lower odds of PE compared with heterosexual orientation. Further studies are warranted to elucidate the clinical significance of these findings and whether they reflect differences in patterns of sexual lifestyle.

Frozen Goals (neither actively working to achieve the goal nor abandon it): 92% reported having at least one frozen goal in their life, thereby demonstrating that frozen goals are not attributable to individual differences
Davydenko, M., Werner, K. M., & Milyavskaya, M. (2019). Frozen Goals: Identifying and Defining a New Type of Goal. Collabra: Psychology, 5(1), 17. DOI: http://doi.org/10.1525/collabra.194
Abstract: Goals pursuit involves multiple stages from setting the goal to actively pursuing the goal to finally achieving or abandoning the goal. Sometimes, however, individuals may set a goal and take some steps towards achieving it, but after some time they are neither actively working to achieve the goal nor abandon the goal. We describe such goals as ‘frozen goals’: personally important goals that individuals remain committed to (and so are not abandoned), yet no steps are actively taken towards attaining the goal. Across three studies we demonstrate the prevalence of frozen goals (Study 1) and examine differences between frozen goals and current goals that are actively pursued (Study 2) and between current frozen goals and past frozen goals (Study 3). In Study 1 we find that 92% of the sample reported having at least one frozen goal in their life, thereby demonstrating that frozen goals are not attributable to individual differences. In Study 2, we found that participants randomly assigned to describe a frozen goal reported making less progress, were less committed to, and considered the frozen goals less important than current goals. However, frozen goal commitment and importance was significantly greater than the scale midpoint, suggesting that frozen goals are nonetheless important. Across the studies, we found that frozen goals are common and are maintained for many years with very little progress, but that shifts from frozen to active or abandoned goals are possible. This research opens many avenues for new questions and new perspectives on goal pursuit and goal setting.

In certain aspects, frozen goals seem like nothing more than fantasies of what people want to achieve. However, although some elements of frozen goals and fantasies may overlap (e.g., lack of effort, progress), frozen goals are more than merely fantasies (i.e., images of future experiences of desired events, independent of reality; Oettingen et al., 2001). Unlike fantasies, frozen goals are considered important to both have and to achieve (Study 1–3). If people approached their frozen goals as they do fantasies, there would be no need for achievement because a fantasy does not need to be achieved. By definition, fantasies are independent of the likelihood that they will actually occur (Oettingen et al., 2001). All present studies demonstrated that frozen goals are not limited to certain types of aspirational goals that are beyond the realm of achievement; the types of frozen goals people have (e.g., lose weight, buy a house) are indeed achievable goals. Not only are frozen goals attainable in principle, individuals also report believing they will attain the goal at some point in the future, thereby distinguishing them from fantasies or from irrevocable goals (Miceli, & Castelfranchi, 2017). Furthermore, we found no differences in positive or negative affect when individuals thought about the frozen goals they achieved, abandoned, or are currently maintaining, suggesting that, unlike irrevocable goals, frozen goals do not impact one’s emotional well-being.

State-owned enterprises concentration in a given sector has a statistically significant negative effect on private fixed capital formation; the impact is stronger in those industries in which SOEs have a more dominant presence
You Are Suffocating Me! Firm-Level Evidence on Crowding Out. Serhan Cevik. IBM Working Paper No. 19/80, April 24, 2019. https://www.imf.org/en/Publications/WP/Issues/2019/04/24/You-Are-Suffocating-Me-Firm-Level-Evidence-on-Crowding-Out-46720
Summary: Literature on whether government spending crowds out or crowds in the private sector is large, but still without an unambiguous conclusion. Using firm-level data from Ukraine, this paper provides a granular empirical investigation to disentangle the impact of state-owned enterprises (SOEs) on private firm investment in Ukraine—a large transition economy. Controlling for firm characteristics and systematic differences across sectors, the results indicate that the SOE concentration in a given sector has a statistically significant negative effect on private fixed capital formation, and that the impact of SOEs is stronger in those industries in which SOEs have a more dominant presence. These findings imply that private firms operating in sectors with a high level of SOE concentration invest systematically less than businesses that are not competing directly with SOEs.
