Bricolage in organizations

Cunha, Miguel Pina e - Faculdade de Economia, Universidade Nova de Lisboa - 2005

Theories of management and organization have traditionally overlooked the concept of bricolage. Focused on the rationality of resource allocation, scholars have missed the relevance of the skill of “inventing” resources from available materials. Changes in the nature of competition are,...

Fixed-Mobile Integration

Hoernig, Steffen - 2014

Often, fi xed-line incumbents also own the largest mobile network. We consider the effect of this joint ownership on market outcomes. Our model predicts that while fixed-to-mobile call prices to the integrated mobile network are more efficient than under separation, those to rival mobile...

Price Distortion Under Fixed-Mobile Substitution

Bourreau, Marc - 2015

This paper analyses the impact of substitution between fixed and mobile telephony on call prices. We develop a model where consumers differ in the benefits of mobility and firms price discriminate between on-net and off-net calls. We find that call prices are distorted downwards due to...

Three Equivalent Salop Models and Their Normative Representative Consumer

Hoernig, Steffen - 2015

We show that three location models on the Salop circle, involving linear or quadratic transport cost, and asymmetric locations or fixed benefits, are equivalent: they lead to the same demand functions and consumer surplus. The only exception is the case of asymmetric locations with an even...
