Layoff tax and employment of the elderly

In 1996 Austria introduced a tax for the layoff of older workers, which was tightened in 2000. The regulation requires employers to pay a tax of up to 170% of the gross monthly income when they give notice to employees aged 50 or more. We use data from Austrian social security records to investigate if such layoff taxes lead to less firing of older workers. We compare a control group of workers aged nearly 50 with the treatment group above 50. We apply a difference-in-difference approach to analyze the difference in the displacement probability of all prime aged workers. Results show substantial reductions in layoff behavior for workers aged 50 and above after the tightening of the tax.     

Non-tariff barriers and the Uruguay Round

The use of non-tariff barriers to trade, which began to be important in the 1970s, has continued to increase throughout the 1980s. Notwithstanding the difficulties and limitations it faces, the Uruguay Round probably presents the only present opportunity of coming to grips with many existing exemptions to, and distortions of, GATT rules.     

Lags and Leads in Life Satisfaction in Korea: When Gender Matters

Using detailed longitudinal data from the Korean Labor and Income Panel Study (KLIPS) from 1998 to 2008, this paper finds significant gender differences in impacts as well as adaptation patterns to major life and labor market events in Korea. Men remain on a higher happiness level throughout marriage, while women return to their baseline happiness within only two years. Consequently, men suffer more from divorce and the death of a spouse. This marital gender happiness gap is equivalent to a (husband only) increase of annual per capita household income of approximately US$17,800. The study further finds that men suffer more from unemployment. Results are robust to the inclusion of multiple simultaneous events and the use of different estimators.     

Strategic Manipulation of Preference Information in Multi-Criteria Group Decision Methods

When group decisions involve the allocation of resources to group members, the members might have an incentive to strategically distort any information they provide in order to increase their share of resources. The paper compares several multi-criteria group decision methods with respect to this problem. We show, using a computational model, that strategic manipulation of preference information is possible in all of the methods considered, although to a different extent. Furthermore, when the solution a method generates under correct information is not Pareto-optimal, manipulation attempts might even improve the efficiency of outcomes.     

Preference Structures of Negotiators and Negotiation Outcomes

Using a database collected during about 3,000 negotiation experiments, this paper analyzes how specific features of utility functions of negotiators, like attribute weights, monotonicity and convexity of marginal utility functions, are reflected in the outcomes of negotiations. We find that compromise values are to a considerable extent influenced by the utility functions. There are also significant impacts on the likelihood of achieving a compromise, but the model fit is considerably less than for compromise values.     

Vor der Europawahl: Wie lässt sich die demokratische Legitimität verbessern?

The EU suffers from a democratic deficit that arises not first and foremost from a lack of institutional competencies, but rather from the double weakness of politics vis-à-vis economics and law at the European level. This “functional democratic deficit” renders the existing mechanisms of democratic control increasingly ineffective. Especially for its citizens, a politically integrated Europen Union might be difficult to grasp, and it may only be reached gradually through a continuous process of dynamic development; however, “United in Diversity” seems to be the better alternative, and not only for historical reasons. The direct elections for the European Parliament, although not denying deficits of democratic legitimacy and participation at the Union level, should not be underestimated in their legitimising influence for the Union as an associated structure of members without obvious hierarchies.     

Orthogonalized factors and systematic risk decomposition

In the context of linear multi-factor models, this study proposes an egalitarian, optimal and unique procedure to find orthogonalized factors, which also facilitates the decomposition of the coefficient of determination. Importantly, the new risk factors may diverge significantly from the original ones. The decomposition of risk allows one to explicitly examine the impact of individual factors on the return variation of risky assets, which provides discriminative power for factor selection. The procedure is experimentally robust even for small samples. Empirically we find that even though, on average, approximately eighty (sixty-five) percent of style (industry) portfolios’ volatility is explained by the market and size factors, other factors such as value, momentum and contrarian still play an important role for certain portfolios. The components of systematic risk, while dynamic over time, generally exhibit negative correlation between market, on one side, and size, value, momentum and contrarian, on the other side.
