Conflict,Participative Decision‐Making,and Generational Ownership Dispersion: A Multilevel Analysis*

This study examines how participative decision‐making and generational ownership dispersion affect conflict in a sample of privately held U.S. family firms. Our study utilizes a hierarchical linear model approach to investigate “cross‐level” effects between variables from different levels of analysis. Participative decision‐making among family members was found to be associated with cognitive and relationship conflict. Furthermore, the relationship between participative decision‐making and conflict as individual‐level variables was moderated by generational ownership dispersion, a firm‐level variable. When ownership was dispersed through multiple generations, participative decision‐making was found to be positively related to cognitive and relationship conflict; however, in one‐ and two‐generation ownership firms participative decision‐making was found to be negatively related to cognitive and relationship conflict.     

Economic growth, skill-biased technical change and wage inequality: A model and estimations for the US and Europe

In recent literature skill-biased technical change has been viewed as a major cause for wage inequality. Some modelling and presentation of stylized facts have been undertaken for US time series data. A preliminary study of wage inequality in a model with knowledge as input in an aggregate production function has been presented by Riddell and Romer [General Purpose Technologies and Economic Growth, 1998, MIT Press]. Although some important forces determining wage inequality are widely accepted we know little about the quantitative impact of each source and differences across countries. We present a growth model of the Romer type with innovation-based technical change and two skill groups where the growth of knowledge, the relative supply of the two skill groups, externalities and substitution effects among the two groups are the driving forces for wage inequality. We undertake estimates for US time series data and contrast those estimates with results from some European countries. In particular, we compare parameter estimations for US and German time series data. The paper concludes that there is less wage inequality across skills in Europe in contrast to the US on the macroeconomic level. But, considering disaggregated data we observe some increases in inequality for Germany, too. Although our model reveals important variables for the explanation of wage inequality there may, however, also be other factors, such as trade unions, which have impacted the wage spread.     

On the optimal exploitation of interacting resources

The paper demonstrates — partly analytically and partly numerically — that traditional results in resource economics obtained from the study of only one resource do not carry over to ecologically interacting resources. As in the traditional approach, we also employ dynamic optimization. The limiting behavior of the trajectories is first studied analytically by letting the discount rate approach infinity. A numerical study is then undertaken by means of a dynamic programming algorithm in order to explore the fate of the resources for various finite discount rates. The relation of our results to results in optimal growth theory is also discussed.
