Measurement of merger gains using post-merger data is sifficult and highly conjectural. Thus, it is difficult to test merger theories and to estimate merger gains using such data. The approach in the current paper is to use pre-merger data in an economic model, in order to test the managerial...

The choice of model of normal returns in event studies has been widely discussed in the literature. While researchers frequently continue to use an array of alternatives, there is currently some tendency to favour cruder but simpler mean- or market-adjusted returns models. This paper presents a...

Long run persistence in company profits is analyzed for 156 US companies over a fifty-year period using AR1 and structural time series tests. A statistically significant degree of consitstency is found between them in identifying firms persistently above or below the competitive norm. However,...

A measure of market share mobility is derived from an hypothesized model of underlying market share behavior. Explicit linkage of the two exposes some properties of the index and its implied behavioral assumptions and informs empirical work. Results for the U.K. newspaper industry offer some...

It has long been recognised that one of the most important features of a production technology lies in its implications for managerial control over the production process. Amongst early writers, Charles Babbage observed : "One great advantage which we may derive from machinery is from the check...

West Germany's recovery and growth to a position of economic leadership over most other industrialized nations appears to have been achieved without the aid of widespread merger activity, at least up to the late nineteen-sixties. Although the official statistics understate the true number of...

Merger activity in West Germany remained at a low level in comparison with most industrialized countries until the late nineteen-sixties, but has increased very rapidly since then. Mergers notified to the Federal Cartel Office under section 23 of the 1958 Act Against Restraint of Competition...
