FAMILY OWNERSHIP AND CONTROL IN LARGE FIRMS: THE GOOD, THE BAD, THE IRRELEVANT -- AND WHY

There is a major debate regarding the role of concentrated family ownership and control in large firms, with three positions suggesting that such concentration is (1) good, (2) bad, or (3) irrelevant for firm performance. This article reports two studies to shed further light on this debate. Study 1 uses 744 publicly listed large firms in eight Asian countries to test competing hypotheses on the impact of the combination of family ownership and control on firm performance. On a country-by-country basis, our findings support all three positions. On an aggregate, pooled sample basis, the results support the “irrelevant” position. Study 2, based on a sample of 688 firms from the same eight Asian countries, endeavors to answer why Study 1 obtains different results for different countries. We theorize and document that Study 1 findings may be systematically associated with the level of shareholder protection embodied in legal and regulatory institutions. Study 2 thus sketches the contours of a cross-country, institution-based theory of corporate governance. Overall, our two studies lead to a finer-grained and more cumulative understanding of the crucial debate on family ownership and control in large firms.http://deepblue.lib.umich.edu/bitstream/2027.42/57220/1/wp840 .pd

Towards the physical vacuum of cosmic inflation

There have been long debates about the initial condition of inflationary perturbations. In this work we explicitly show the decay of excited states during inflation via interactions. For this purpose, we note that the folded shape non-Gaussianity can be interpreted as the decay of the non-Bunch-Davies initial condition. The one loop diagrams with non-Bunch-Davies propagators are calculated to uncover the decay of such excited states. The observed smallness of non-Gaussianity keeps the window open for probing inflationary initial conditions and trans-Planckian physics
