Abstract
We study the impact of firms’ abnormal business operations on their future crash risk in stock prices. Computed based on real earnings management (REM) models, firms’ deviation in real operations (DROs) from industry norms is shown to be positively associated with their future crash risk. This association is incremental to that between discretionary accruals (DAs) and crash risk found by prior studies. Moreover, after Sarbanes–Oxley Act (SOX) of 2002, DRO’s predictive power for crash risk strengthens substantially, while DA’s predictive power essentially dissipates. These results are consistent with the prior finding that managers shift from accrual earnings management to REM after SOX. We further develop a suspect-firm approach to capture firms’ use of DRO for REM purposes. This analysis shows that REM-firms experience a significant increase in crash risk in the following year. These findings suggest that the impact of DRO on crash risk is at least partially through REM.

A Weighty Issue Revisited: The Dynamic Effect of Body Weight on Earnings and Satisfaction in Germany
Frieder Kropfhäußer, Marco Sunder
Applied Economics,
No. 41,
2015
Abstract
We estimate the relationship between changes in the body mass index (bmi) and wages or satisfaction, respectively, in a panel of German employees. In contrast to previous findings, our dynamic models indicate an inverse u-shaped association between bmi and wages. As the implied maximum occurs in the ‘overweight’ category, the positive trend in weight may not yet constitute a major limitation to productivity. Further investigation points out a stronger association among young workers and workers with jobs that are less protected. Work satisfaction of young workers is associated with bmi beyond the effect of earnings.

Returns to Skills around the World: Evidence from PIAAC

European Economic Review,
January
2015
Abstract
Existing estimates of the labor-market returns to human capital give a distorted picture of the role of skills across different economies. International comparisons of earnings analyses rely almost exclusively on school attainment measures of human capital, and evidence incorporating direct measures of cognitive skills is mostly restricted to early-career workers in the United States. Analysis of the new PIAAC survey of adult skills over the full lifecycle in 23 countries shows that the focus on early-career earnings leads to underestimating the lifetime returns to skills by about one quarter. On average, a one-standard-deviation increase in numeracy skills is associated with an 18 percent wage increase among prime-age workers. But this masks considerable heterogeneity across countries. Eight countries, including all Nordic countries, have returns between 12 and 15 percent, while six are above 21 percent with the largest return being 28 percent in the United States. Estimates are remarkably robust to different earnings and skill measures, additional controls, and various subgroups. Instrumental-variable models that use skill variation stemming from school attainment, parental education, or compulsory-schooling laws provide even higher estimates. Intriguingly, returns to skills are systematically lower in countries with higher union density, stricter employment protection, and larger public-sector shares.

How Can Skill Mismatch be Measured? New Approaches with PIAAC

No. 2,
2014
Abstract
Measuring skill mismatch is problematic, because objective data on an individual skill level are often not available. Recently published data from the Program for the International Assessment of Adult Competencies (PIAAC) provide a unique opportunity for gauging the importance of skill mismatch in modern labor markets. This paper systematically compares existing measures of skill mismatch in terms of their implications for labor market outcomes. We also provide a new measure that addresses an important limitation of existing measures, namely, assigning a single competency score to individuals. We find that the importance of skill mismatch for individual earnings differs greatly, depending on the measure of mismatch used.

A Weighty Issue Revisited: The Dynamic Effect of Body Weight on Earnings and Satisfaction in Germany
Frieder Kropfhäußer, Marco Sunder
Abstract
We estimate the relationship between changes in the body mass index (bmi) and wages or satisfaction, respectively, in a panel of German employees. In contrast to previous literature, the dynamic models indicate that there is an inverse u-shaped association between bmi and wages among young workers. Among young male workers, work satisfaction is affected beyond the effect on earnings. Our finding of an implied optimum bmi in the overweight range could indicate that the recent rise in weight does not yet constitute a major limitation to productivity.

The Tradeoff Between Redistribution and Effort: Evidence from the Field and from the Lab

No. 10,

Abstract
We use survey and experimental data to explore how effort choices and preferences for redistribution are linked. Under standard preferences, redistribution would reduce effort. This is different with social preferences. Using data from the World Value Survey, we find that respondents with stronger preferences for redistribution tend to have weaker incentives to engage in effort, but that the reverse does not hold true. Using a lab experiment, we show that redistribution choices even increase in imposed effort. Those with higher ability are willing to help the needy if earning income becomes more difficult for everybody.

On the Economic Architecture of the Workplace: Repercussions of Social Comparisons among Heterogeneous Workers
Oded Stark, Walter Hyll
Journal of Labor Economics,
No. 2,
2011
Abstract
We analyze the impact on a firm’s profits and optimal wage rates, and on the distribution of workers’ earnings, when workers compare their earnings with those of co-workers. We consider a low-productivity worker who receives lower wage earnings than a high-productivity worker. When the low-productivity worker derives (dis)utility not only from his own effort but also from comparing his earnings with those of the high-productivity worker, his response to the sensing of relative deprivation is to increase the optimal level of effort. Consequently, the firm’s profits are higher, its wage rates remain unchanged, and the distribution of earnings is compressed.

Ageing and Labour Markets: An Analysis on the effect of worker’s age on productivity, innovation and mobility
Lutz Schneider
Technische Universität Dresden. Dissertation,
2011
Abstract
The present study analyses the labour market effect of workers’ ageing. Explicitly, the impact of age on productivity and wages, on innovation as well as on mobility is explored empirically. The econometric analyses are based on firm and employment data from the Institute for Employment Research (IAB) and, thus, refer to the labour market of Germany. Regarding the productivity and wage effects of age the econometric results confirm a positive correlation between firm productivity and the share of middle-aged employees (41-50 years old) within the manufacturing sector. Hence, the results provide evidence of an inverted u-shaped age-productivity profile in this sector also found for other countries. Furthermore, age-wage and age-productivity profiles seem to follow unequal patterns. Compared to the group of the 15-30 and the 51 and above years old workers the group of middle-aged employees earn less than a productivity based wage scheme would require. In terms of age effects on innovativeness the micro-econometric analysis again reveals an inverted u-shaped profile. Workers aged around 40 years seem to act as key driver for innovation activities within firms. An additional finding concerns the impact of age diversity on innovation. The expected positive effect of a heterogeneous age structure is not confirmed by the data. With respect to labour market mobility results are in favour of a negative correlation between age and job mobility either in terms of changing professions or firms. The estimation of a multi equation model verifies that expected wages of older workers do not or only marginally increase due to job mobility, so, financial incentives to change jobs are very low. Yet, even after controlling the absent wage incentive older employees still remain more immobile than younger workers. Altogether, these results should not only be of academic interest but also informative for actors on the firm and the governmental level. Both sides are asked to cope with the challenges of demographic change. Only by maintaining productivity and innovativeness until old ages the necessary resources can be generated to preserve an economy’s prosperity even if the share of non-active population is increasing by demographic developments. Secondly, enhancing productivity is essential to ensure employability of older persons and to sustain the size of workforce even in the circumstances of an ageing economy.

Human Capital in a regional Comparison of East and West Germany: Catching up of the New Laender

Wirtschaft im Wandel,
No. 7,
2010
Abstract
The endowment with human capital is not only a factor that strongly influences the region’s current economical potential, but also has a considerable effect on its future economical potential, i.o.w. economic growth. Human capital describes the employable peoples’ skills and their personal knowledge, which can be used in the production of goods and services as well as in the further development of them.
The public debate about East Germany’s economic development is referring to this crucial relation when exposing the problems of the medium-term development of the supply of professionals or the firm’s research- and development intensity. For a better assessment of the situation on the aggregation level of the New Laender this article attempts to estimate the human capital endowment and its evolution over time in comparison to West Germany.
The average human capital of the employed persons and the labour force potential is estimated by means of the earned income for East and West Germany separately. As a result the average human capital of the employed persons can be shown to have risen slightly from 1995 to 2004 in East Germany while there is nearly no increase in West Germany. This may be considered as a catching-up process, without already having led to equalization.

Economic Effects of the Halle Institute for Economic Research
Ulrich Blum
Wirtschaft im Wandel,
No. 10,
2008
Abstract
The most important approach to assess the scholarly performance of an institute is to evaluate its academic output. Economic research institutes such as the Halle Institute for Economic Research (IWH) furthermore are targeted at providing policy advice to public authorities. This adds an additional criterion, the ability to impact policy discussions in Germany and beyond.
A rarely discussed issue is the effect of an institute on the local economy. The IWH is located in a region of East Germany that is still catching up economically. Transformation problems are still very visible. In such an economic environment, the expenditures of an institute play an important role in stabilizing local demand. The analysis shows, by using input-output-methods, that the most important factor for the local economy is the demand stemming from wages earned by the employees of the institute. Especially the local area, where most of the staff lives, heavily benefits from this effect. Expenditures of about 4.6 million Euros which include the salaries of the staff of about 70 persons generates sufficient demand in the area to guarantee employment for another 35 persons. In addition, as crowding out of activities by additional demand is presently not an issue in East Germany, the taxes generated account for a considerable part of the budget.
