In this research, we seek to advance the understanding of heterogeneity in entrant survival rates. We suggest that the innovative environment at the time of entry can explain the variation in likelihood of survival for entrants. We conceptualize innovative environment in terms of two dimensions: the technological regime operating in a specific industry at the time of entry, and the technology i...

In this article, I investigate the capacity investment cost conditions where a multiproduct market leader may respond to a focus strategy entrant by using different strategies such as changing the product mix, production volumes, quality levels, and/or by investing in more capacity. The products offered in the market are quality differentiated and customers are heterogeneous in their willingnes...

This paper shows that differences in brand image and product quality (horizontal and vertical differentiation) can govern the market-entry decisions of firms facing a market already served by an incumbent. The entrant might sell under its own brand, become a supplier to the incumbent (called an OEM arrangement), or both. Findings reveal that when firms are vertically but not horizontally differ...

BACKGROUND In patients with atrioventricular nodal re-entrant tachycardia, modifications of the antegrade atrioventricular nodal function curve caused by catheter ablation of the so-called slow pathway are heterogeneous, but have not yet been systematically evaluated. AIM To test the hypothesis that successful treatment is independent of specific electrophysiological modifications of atrioven...

Focusing on a femtocell communications market, we study the entrant network service provider’s (NSP’s) longterm decision: whether to enter the market and which spectrum sharing technology to select to maximize its profit. This long-term decision is closely related to the entrant’s pricing strategy and the users’ aggregate demand, which we model as medium-term and short-term decisions, respectiv...

We consider in this paper the two-machine no-wait flowshop problem in which each machine may have an unavailable interval. We present 3 2 -approximation algorithms for the problem when the unavailable interval is imposed on only one machine, or the unavailable intervals on the two machines overlap. These algorithms improve on existing results.

OBJECTIVE To compare the outcome of cryothermal and radiofrequency energy transcatheter ablation of atrioventricular junctional re-entrant tachycardia in children and adolescents. DESIGN Case series with internal comparison. SETTING Two hospitals in Hong Kong. PATIENTS Consecutive transcatheter ablation procedures for atrioventricular junctional re-entrant tachycardia in children and adol...

The paper explores the role of R&D investments reducing fixed production costs in entry deterrence. An incumbent monopolist performs R&D to reduce its fixed production costs. There is a potential entrant, which can also perform R&D for the same purpose. There are bidirectional technological spillovers between the incumbent and the potential entrant. It is shown that deterrence, which takes the ...

We analyze the incentives of a vertically integrated firm, which is a regulated monopolist in the wholesale market and competes with an entrant in the retail market, to invest and to give access to a new wholesale technology. The new technology is unregulated and produces retail products of a higher quality than the old technology. If the innovation is non-drastic, the vertically integrated fir...
