Do people really adapt to marriage?

Although cross-sectional studies have shown a reliable association between marital status and subjective well-being, a recent longitudinal study (Lucas, Clark, Georgellis, & Diener, 2003) found no support for the idea that happiness increases after marriage. Instead, participants who got married reported short-term increases followed by complete adaptation back to baseline levels of well-being. However, researchers have criticized this study on two grounds. First, these results contradict cohort-based analyses from a nationally representative sample. Second, these analyses do not control for pre-marriage cohabitation, which could potentially inflate baseline levels of well-being. The original data (plus four additional waves) are reanalyzed to address these concerns. Results confirm that individuals do not get a lasting boost in life satisfaction following marriage.life satisfaction anticipation ; habituation ; marriage ; cohabitation

Lags and Leads in Life Satisfaction: A Test of the Baseline Hypothesis

We use fourteen waves of the German panel data to ask whether individuals, after life and labour market events, return to some baseline wellbeing level. Although the strongest life satisfaction effect is often at the time of the event, significant lag and lead effects are present. Men are more affected by labour market events (unemployment and layoffs) and women by life events (marriage and divorce). Anticipation is an important component of individual wellbeing. Last, we show that happiness does not provide insurance against hard knocks: those with high baseline satisfaction are most adversely affected by negative events.Life Satisfaction; Anticipation; Habituation; Baseline Satisfaction; Labour Market and Family Events

Lags and Leads in Life Satisfaction: A Test of the Baseline Hypothesis

We look for evidence of habituation in twenty waves of German panel data: do individuals, after life and labour market events, tend to return to some baseline level of well-being? Although the strongest life satisfaction effect is often at the time of the event, we find significant lag and lead effects. We cannot reject the hypothesis of complete adaptation to marriage, divorce, widowhood, birth of child, and layoff. However, there is little evidence of adaptation to unemployment. Men are somewhat more affected by labour market events (unemployment and layoffs) than are women, but in general the patterns of anticipation and adaptation are remarkably similar by sex.life satisfaction, anticipation, adaptation, baseline satisfaction, labour market and lifeevents

Rodent Populations and Crop Damage in Minimum Tillage Corn Fields

No-till and disked cornfields were examined in southwest Iowa to determine small mammal population densities, movements, and impacts of rodent depredations on corn seedlings. Two replicates of the treatments corn planted into. corn stubble, corn planted into chemically treated sod, and corn planted into spring-disked fields were studied during the 1982 and 1983 growing seasons. Grids of 100 Sherman live traps were established at the edge and middle of each field to determine rodent densities and document possible encroachment of small mammals from nearby habitats. Trapping experiments were conducted for 6 consecutive days during May, August, and November. To assess crop damage, 5 164 ft. (50 m) transects were established in the edge and middle of each field. Corn seedlings were examined every other day for the first 10 days post-emergence

The Compositional Structure of the Asteroid Belt

The past decade has brought major improvements in large-scale asteroid discovery and characterization with over half a million known asteroids and over 100,000 with some measurement of physical characterization. This explosion of data has allowed us to create a new global picture of the Main Asteroid Belt. Put in context with meteorite measurements and dynamical models, a new and more complete picture of Solar System evolution has emerged. The question has changed from "What was the original compositional gradient of the Asteroid Belt?" to "What was the original compositional gradient of small bodies across the entire Solar System?" No longer is the leading theory that two belts of planetesimals are primordial, but instead those belts were formed and sculpted through evolutionary processes after Solar System formation. This article reviews the advancements on the fronts of asteroid compositional characterization, meteorite measurements, and dynamical theories in the context of the heliocentric distribution of asteroid compositions seen in the Main Belt today. This chapter also reviews the major outstanding questions relating to asteroid compositions and distributions and summarizes the progress and current state of understanding of these questions to form the big picture of the formation and evolution of asteroids in the Main Belt. Finally, we briefly review the relevance of asteroids and their compositions in their greater context within our Solar System and beyond.Comment: Accepted chapter in Asteroids IV in the Space Science Series to be published Fall 201

Do wages underestimate the inequality in workers' rewards? The joint distribution of job quality and wages across occupations

Information on both wages and job quality is needed in order to understand the occupational dispersion of wellbeing. We analyse subjective wellbeing in a large UK sample to construct a measure of ‘overall reward’, the sum of wages and the value of job quality, in 90 different occupations. If only wages are included, then labour market inequality is underestimated: the dispersion of overall rewards is one-third larger than the dispersion of wages. Our findings are similar, and stronger, in data on US workers. We find a positive correlation between job quality and wages in all specifications, both between individuals in the cross-section and within individuals in panel data. The gender and ethnic gaps in the labour market are larger than those in wages alone, and the overall rewards to education on the labour market are underestimated by earnings differentials alone

Beyond income inequality: factoring in non-monetary rewards

While many researchers, policy makers, and interest groups are concerned with income inequality and its impact on society, much of the debate has focused on inequality in wages. In contrast, relatively little work has addressed the job rewards that are not monetary. But, as Andrew Clark, Maria Cotofan, and Richard Layard write, we need to look beyond wages to fully capture labour market inequality
