An extensive empirical literature in strategy and finance studies the performance implications of corporate diversification. Two core debates in the literature concern the existence of a diversification discount and the relative importance of industry relatedness and market structure for the...

We investigate the relationship between product diversification and performance in the Dutch property-liability (P&L) insurance industry for the period 2007-2018. We employ a two-step approach: we first investigate the drivers of diversification and, as a second step, we investigate the impact...

Procurement within the NHS is attracting increasing research and policy interest. However, most of the emphasis has been on the buyer (the NHS), with less attention paid to the behaviour of suppliers (often pharmaceutical companies). For medical devices very little is publicly documented about...

In this short research note we investigate the role of diversification in the firm growth process. We build on Penrose's (1959) Theory of the Growth of the Firm to formulate hypotheses about growth of employment, assets, and sales in the years before, during and after a new product introduction....

Product scope adjustment is a key mechanism through which multi-product firms achieve efficient resource allocations. In this paper, we take a novel perspective to study firms' product scope adjustment behavior through the lens of asset pricing. Using a unique panel scanner data set containing...

Recent research questions the existence of a conglomerate discount. This study addresses two of the most important explanations for the conglomerate discount and finds evidence in support of an economically and statistically significant discount. The first explanation is that the risk-reducing...

Over the period 1980-2007 multinational firms' investment grew four times faster than worldwide GDP. Yet the evidence on whether global diversification is valuable is inconclusive. This paper uses detailed FDI data for 251 UK multinational firms and 4,676 subsidiaries to show that multinational...

We propose and test a view of corporate diversification as a strategy that exploits internal information markets, by bringing together information that is scattered across the economy. First, we construct an inter-industry network using input-output data, to proxy for the economy's information...
