Measuring Inefficiency Via Potential Improvements

In a recent paper Bogetoft and Hougaard (1999) suggest the use of a new potential improvements approach to efficiency evaluation which has the advantage of separating the issue of benchmark selection from the issue of efficiency measurement. In the present paper the potential improvements inefficiency index is reexamined and a DEA-like approach for its determination is suggested. The approach is called Multi-directional Efficiency Analysis (MEA). An empirical example on Danish dairy farms is used for illustrative purposes and comparisons with various versions of DEA.     

Foreign ownership and long‐term survival

We study the relative survival of foreign‐ and domestically owned companies in Denmark over more than a century (1895–2005). Contrary to previous studies that have emphasized the liability of foreignness, we find evidence of a significant survival premium for foreign‐owned companies; however, the premium declines over time and disappears entirely in the last decade leading up to 2005. Further evidence indicates that the foreign survival premium is negatively influenced by new foreign entry, and that the long‐run decline is caused by increasing competition between foreign subsidiaries.
