Die politische Ökonomie wachsender Ungleichverteilung der Einkommen

In dealing with growing income inequality, economists and social scientists have ignored the interdependencies between economic performance, voter turnout and people’s psychological damages and social deprivations. This article emphasises the role of demography for the bargaining power of trade unions and employer associations. It demonstrates the concomitance of full employment and shrinking income inequality and, correspondingly high unemployment and growing income inequality. Due to the decrease in the size of the labour force in Germany since 2005, the gap between higher and lower incomes will soon become smaller, and many economic and social problems can be solved.     

Das Rentenpaket 2014 — eine ökonomische Beurteilung

The 2014 pension reform has three main components. First disability pensions have been increased by about two earnings points, an average monthly gain of 40 euros. In addition low wages in the four years preceding disability-related retirement will now be disregarded. However, since these new rules only apply to retirement after July 2014 they fail to fight poverty among current disability-related retirees. Second an additional credit for all births before 1992 (“mothers’ pension”) is extremely costly and unnecessary. Poverty prevention is weak due to a strict income test in the welfare system for the elderly. Third early retirement at age 63 without actuarial adjustment has been reintroduced This is a costly measure with negative effects on both equality and efficiency. The additional child credit and early retirement provisions reduce the financial and social sustainability of the German public pension system.     

Utilizing the firm's resources: How TMT heterogeneity and resulting faultlines affect TMT tasks

While theory and evidence show that firms' competitive actions mediate the resource‐performance relationship, details of top managements' roles in shaping resource utilization choices have been underemphasized. We address this oversight by integrating top management team heterogeneity and any resulting faultline strength with the resource‐action‐performance model to investigate how TMT composition differentially affects the model's two linkages. Specifically, we argue that TMT heterogeneity positively affects the resource‐action linkage, yet negatively affects the action‐performance linkage. Moreover, when heterogeneity begets strong faultlines, all such positive effect is lost. Supportive evidence from the in‐vitro medical diagnostic substance manufacturing industry allows us to discuss how our findings contribute to upper echelons theory, as well as the emerging stream on resource utilization.

Cost effectiveness of a 92-gene assay for the diagnosis of metastatic cancer

Objectives:

To estimate the clinical and economic trade-offs involved in using a molecular assay (92-gene assay, CancerTYPE ID) to aid in identifying the primary site of difficult-to-diagnose metastatic cancers and to explore whether the 92-gene assay can be used to standardize the diagnostic process and costs for clinicians, patients, and payers.

Methods:

Four decision-analytic models were developed to project the lifetime clinical and economic impact of incorporating the 92-gene assay compared with standard care alone. For each model, total and incremental costs, life-years, quality-adjusted life-years (QALYs), incremental cost–effectiveness ratios (ICERs), and the proportion of patients treated correctly versus incorrectly were projected from the payer perspective. Model inputs were based on published literature, analyses of SEER (Surveillance Epidemiology and End Results) data, publicly available data, and interviews with clinical experts.

Results:

In all four models, the 92-gene assay increased the proportion of patients treated correctly, decreased the proportion of patients treated with empiric therapy, and increased quality-adjusted survival. In the primary model, the ICER was $50,273/QALY; thus, the 92-gene assay is therefore cost effective when considering a societal willingness-to-pay threshold of $100,000/QALY. These findings were robust across sensitivity analyses.

Conclusions:

Use of the 92-gene assay for diagnosing metastatic tumors of uncertain origin is associated with reduced misdiagnoses, increased survival, and improved quality of life. Incorporating the assay into current practice is a cost-effective approach to standardizing diagnostic methods while improving patient care. Limitations of this analysis are the lack of data availability and resulting modeling simplifications, although sensitivity analyses showed these to not be key drivers of results.     

Agriculture and climate change in global scenarios: why don't the models agree

Agriculture is unique among economic sectors in the nature of impacts from climate change. The production activity that transforms inputs into agricultural outputs involves direct use of weather inputs (temperature, solar radiation available to the plant, and precipitation). Previous studies of the impacts of climate change on agriculture have reported substantial differences in outcomes such as prices, production, and trade arising from differences in model inputs and model specification. This article presents climate change results and underlying determinants from a model comparison exercise with 10 of the leading global economic models that include significant representation of agriculture. By harmonizing key drivers that include climate change effects, differences in model outcomes were reduced. The particular choice of climate change drivers for this comparison activity results in large and negative productivity effects. All models respond with higher prices. Producer behavior differs by model with some emphasizing area response and others yield response. Demand response is least important. The differences reflect both differences in model specification and perspectives on the future. The results from this study highlight the need to more fully compare the deep model parameters, to generate a call for a combination of econometric and validation studies to narrow the degree of uncertainty and variability in these parameters and to move to Monte Carlo type simulations to better map the contours of economic uncertainty.

Convergence in the EU

The EU has long viewed economic and institutional convergence as important goals, but the results thus far have been decidedly mixed, and there remain several open questions: How exactly should convergence be defined? How much convergence is necessary? What steps can be taken to improve convergence in the EU, and how can success be defined? Finally, how much convergence can be achieved by improving the economic performance in underperforming regions, and how can convergence in the form of harmonisation towards lower welfare levels be avoided?     

On the Determinants of Mandatory Works Councils in Germany

German works councils are often thought of as operating in all firms that exceed the basic size threshold (of five permanent employees) established under law. Drawing on a new large-scale, representative German data set, we report that only one-fifth of firms in our sample have works councils even if such firms do account for almost three-fourths of employment. The principal factors behind works council presence emerge as fairly conventional: firm size, firm age, branch plant status, the gender composition of the work force, and certain working arrangements. There are also signs of a close relation between workplace union density and council presence. However, some controversial causal links suggested in an earlier econometric literature receive little support.     

Trade Unions and Productivity: The German Evidence

This paper provides a brief review of the empirical evidence on union productivity effects in Germany. The influence of trade unions on productivity is the net effect of conflicting forces which can lead to higher or lower productivity. Although the German dual system of workers' representation via unions and works councils is quite favourable to the existence of productivity-enhancing 'voice' effects, various empirical studies have not been able to detect significant positive net effects of these institutions on productivity.
