We model strategic competition in a market with asymmetric information as a noncooperative game in which each seller competes for a buyer of unknown type by offering the buyer a catalog of products and prices. We call this game a catalog game. Our main objective is to show that catalog games have Nash equilibria. The Nash existence problem for catalog games is particularly contentious due to pa...

Background A doctor’s competence and professionalism is often judged on the basis of attire. Our Lady of Lourdes (OLOL) is a leading Irish hospital in the implementation of Bare Below the Elbows (BBTE) policy, however surgical attire is not standardised and there is great variability in attire worn on wards. We aimed to evaluate patients attitude towards surgeons attire in OLOL.   Methods A pro...

While most advocate that foreign firms should utilize managerial ties to conduct business in China, recent literature cautions that such ties may offer only conditional value. This study examines three sources of heterogeneity that may condition the value of ties: firm ownership (foreign vs. domestic), competition, and structural uncertainty. Results from a survey of 280 firms in China indicate...

This paper examines if interpersonal networks help explain two widely documented empirical patterns of knowledge diffusion: (1) geographic localization of knowledge flows, and (2) easier transmission of knowledge within firms than between firms. A regression framework based on choice-based sampling is used to estimate the probability of micro-level knowledge flow between inventors of U.S. paten...

Although Knowledge has grown to occupy a major role in the discussion on firm performance, we currently know little about the micro-processes involved in search and transfer of knowledge. Drawing on extensive fieldwork in a large, multinational professional service firm, we identify a frequent phenomenon in which employees successfully extend ties to unacquainted others, bypassing direct and in...

Abstract In this paper, we examine to what extent the firm’s propensity be embedded in a network with advantageous structural attributes is driven by its capabilities for management. Specifically, discern management practices on two organizational levels (relationship (RM) and portfolio (PM)) explore their effects three dimensions of local structure (network centrality (NC), knowledge complemen...

The effect of magnetic field on the liquid-liquid equilibrium of two ternary systems (water + acetic acid + butyl acetate and water + acetic acid + dimethyl succinate) at 298.15 K under atmospheric pressure was investigated. The results obtained show that the strength of the magnetic field (0.02 T) affects the solubility of acetic acid in the used organic solvents. Distribution coefficients and...

Liquid-Liquid equilibrium data for the (water + Lactic acid + 2-ethy-1-hexanol) ternary system in T=298.2K and P=1atm were determined and tie- lines related to equilibrium data has been drawn in the phases diagram . The reliability of the experimental tie-line data for this system was as confirmed by using the Hand and Othmer –Tobias correlations. The tie-line data were correlated by means of t...
