Some results on simultaneous confidence intervals for monotone contrasts in one-way anova model

The one-way ANOVA model with common variance is considered. Simultaneous confidence Intervals (SCI) for monotone contrasts in the means are derived and compared to alternative intervals gene¬rated by Williams (1977)     

Twofold optimality of the relative utilitarian bargaining solution

Given a bargaining problem, the relative utilitarian (RU) solution maximizes the sum total of the bargainer’s utilities, after having first renormalized each utility function to range from zero to one. We show that RU is “optimal” in two very different senses. First, RU is the maximal element (over the set of all bargaining solutions) under any partial ordering which satisfies certain axioms of fairness and consistency; this result is closely analogous to the result of Segal (J Polit Econ 108(3):569–589, 2000). Second, RU offers each person the maximum expected utility amongst all rescaling-invariant solutions, when it is applied to a random sequence of future bargaining problems generated using a certain class of distributions; this is recalls the results of Harsanyi (J Polit Econ 61:434–435, 1953) and Karni (Econometrica 66(6):1405–1415, 1998).     

Energy in Eurasia: the Dependency Game

Russia, Europe, and a number of transit countries are involved in a high-stake game about energy which is characterized by a high degree of interdependency and security. The dependencies go in all directions, but what makes the game particularly interesting is that it is neither economically rational nor static. It should lie in all parties' interest to recognize the strong element of interdependency and transform some of the energy security politics into energy economics.     

A tow-stage procedure for testing homogeneity of means against ordered alternatives in analysis of variance with unequal variances

In this paper we present a two-stage sampling procedure for testing the equality of normal means against ordered alternatives in one-way analysis of variance with unequal unknown variances. A table of approximated percentiles needed for implementation is provided. Some Monte Carlo results for estimating the power of the proposed test statistic are presented.     

The labour share of income: heterogeneous causes for parallel movements?

The distribution of factor incomes from a macroeconomic perspective is an increasingly popular research topic—be it for its implications for the personal income distribution or the apparent mistake in previous research declaring it to be constant over time. The labour share has been decreasing across OECD countries since the 1980s, sparking a renewed interest in what is behind this trend. The aim of this paper is to take a systematic approach to estimating the coefficients of factors explaining these movements across countries. In particular, we focus on proper dynamic model specification and test the validity of the homogeneity assumption of slope coefficients frequently implied in previous studies. We employ fixed effect estimators as well as pooled mean group and mean group estimators, the latter in a dynamic heterogeneous panel framework. We find support for a dynamic estimation setup and derive statements regarding the homogeneity assumption with respect to the three most prominent explanatory variables in the literature: the capital-output ratio, total factor productivity and trade openness. We find the first two variables to decrease the labour share, to be better captured by dynamic estimators and to be better identified in more recent time periods. With regard to trade, we see it depressing the labour share since 1980 only. We furthermore provide evidence on increased cross-country homogeneity over time for all of the analysed driving forces of the labour share.
