Countervailing Power and Chain Stores

The countervailing power of large buyers subdues the market power of sellers, but price concessions won by large buyers in upstream markets may or may not translate into lower prices downstream as Galbraith (American capitalism: The concept of countervailing power. Houghton Mifflin, Boston, 1952, Am Econ Rev 44:1–6, 1954) once contended. This paper presents a model that formalizes certain previously neglected elements of Galbraith’s argument, and shows that upstream price concessions may lead to lower downstream prices. In this model, a large retail chain store with countervailing power plays one large supplier off against another to win lower prices. An indirect effect of these interactions is that small retailers also pay lower prices, although not as low as the chain. Finally, competition among the retailers drives retail prices lower. The retail-price-restraining effect of the chain is stronger than the effect that is produced by the entry of an additional supplier.     

The dynamics of emerging economy MNEs: How the internationalization process model can guide future research

The rapid emergence of multinational enterprises (MNEs) from emerging economies calls for a re-assessment of established theories of the MNE. We assess the usefulness of the internationalization process model (IPM), also known as the Uppsala model, to explain the recent strategies of emerging economy MNEs. We argue that popular stages models derived from the IPM are not helpful, but the underlying process of experiential learning driving steps of increased commitment is an important element in explaining the evolution of these MNEs over time. Focusing on the role of acquisitions within internationalization processes, we illustrate our arguments with six case studies of Thai MNEs. On this basis, we discuss how the IPM can inform future research on emerging economy MNEs. Specifically, the IPM suggests focusing on the internal and external factors that may induce firms to accelerate their cycle of international learning and commitment, in particular the roles of networks, acquisitions, human resources, big step commitments, the home country institutional environment, and possible managerial biases.

The linear growth credibility model

Abstract

The investigation of evolutionary models, i.e. models allowing the risk parameter to change in time, has been one of the main topics of research in credibility theory in the last few years. In the present paper a very special (but rather practicable) evolutionary model is defined and recursions for the credibility estimator are stated.     

Capitalizing on Catastrophe: Short Selling Insurance Stocks Around Hurricanes Katrina and Rita

We develop several hypotheses regarding short‐selling activity around Hurricanes Katrina and Rita. We find that abnormal short selling does not increase until 2 trading days after the landfall of Katrina and that short‐selling activity is much more significant around Rita. We find a substantial increase in short‐selling activity in the trading days prior to the landfall of Rita and relatively less short‐selling activity in the trading days after landfall. There is little evidence that suggests that traders short insurance stocks with more potential exposure in the Gulf region than other insurance stocks in the days before landfall.
