In this contribution, at first, we introduce a basic network framework to study pyramidal structures and wedges between ownership and control of companies. Then, we apply it to a dataset of 53.5 million of companies operating in 208 countries. Among others, we detect a strong concentration of...

The objective of this paper is to demonstrate how the boosting approach can be used to define a data-driven board balanced scorecard (BSC) with applications to S&P 500 companies. Using Adaboost, we can generate alternating decision trees (ADTs) that explain the relationship between corporate...

The aim of the research is to create a model of motivation of the top management of government agencies of regions, which will allow to make non-financial motivation of top managers dependent upon the achieved strategic potential of the region and their financial incentives. For this purpose,...

Practitioners and regulators increasingly rely on economic theory to measure bank efficiency and liken institutes with each other. These studies lean first on several methods that could be either stochastic or deterministic and second the input-output definition is based on a production or...

We propose a new approach based on bootstrapping to compare complex networks. This is an important task when we wish to compare the effect of a (policy) shock on the structure of a network. The bootstrap test compares two values of the Gini index, and the test is performed on the difference...

This study examines changes in block ownership for a large sample of listed and non-listed German firms. The frequency of block trading is similar to other countries, and the vast majority of block trades leads to changes in ultimate ownership (control transfers). Such changes are more likely...

This study provides new stylized facts on the determinants of corporate failure and acquisition in Germany. It also offers important lessons for the design of empirical studies. We show that firms experiencing failure or acquisition are significantly different from surviving firms on a number of...

This study investigates the determinants of changes in corporate ownership and firm failure, taking into account different types of sellers and buyers of control blocks. For a large panel of German corporations we find that firms are more likely to fail or to be sold when performance is poor,...

We investigate the role of ownership structure and investor protection in postprivatization corporate governance. We find that the government relinquishes control over time, mainly to the benefit of local institutions and foreign investors. We also show that private ownership tends to...

The current literature on firm ownership around the world shows that concentrated ownership with only one or a few controlling owners is common, especially in many European and Asian countries. The dispersed ownership has proven to be uncommon and even countries with supposed dispersed ownership...
