A Dynamic Model Of Competitive Entry Response, Matthew Selove Dec 2013

A Dynamic Model Of Competitive Entry Response, Matthew Selove

Business Faculty Articles and Research

I develop a dynamic investment game with a “memoryless” research and development process in which an incumbent and an entrant can invest in a new technology, and the entrant can also invest in the old technology. I show that an increase in the probability of successfully implementing a technology can cause the incumbent to reduce its investment. Under certain conditions, if the success probability is high, the incumbent allows the entrant to win the new technology so that firms reach an equilibrium in which they use different technologies, and threats of retaliation prevent attacks; but if the success probability is …


How Do Firms Become Different? A Dynamic Model, Matthew Selove Oct 2013

How Do Firms Become Different? A Dynamic Model, Matthew Selove

Business Faculty Articles and Research

This paper presents a dynamic investment game in which firms that are initially identical develop assets that are specialized to different market segments. The model assumes that there are increasing returns to investment in a segment, for example, as a result of word-of-mouth or learning curve effects. I derive three key results: (1) Under certain conditions there is a unique equilibrium in which firms that are only slightly different focus all of their investment in different segments, causing small random differences to expand into large permanent differences. (2) If, on the other hand, sufficiently large random shocks are possible, firms …


Voice Without Say: Why Capital-Managed Firms Aren’T (Genuinely) Participatory, Justin Schwartz Aug 2013

Voice Without Say: Why Capital-Managed Firms Aren’T (Genuinely) Participatory, Justin Schwartz

Justin Schwartz

Why are most capitalist enterprises of any size organized as authoritarian bureaucracies rather than incorporating genuine employee participation that would give the workers real authority? Even firms with employee participation programs leave virtually all decision-making power in the hands of management. The standard answer is that hierarchy is more economically efficient than any sort of genuine participation, so that participatory firms would be less productive and lose out to more traditional competitors. This answer is indefensible. After surveying the history, legal status, and varieties of employee participation, I examine and reject as question-begging the argument that the rarity of genuine …


A Theory Without A Movement, A Hope Without A Name: The Future Of Marxism In A Post-Marxist World, Justin Schwartz Jun 2013

A Theory Without A Movement, A Hope Without A Name: The Future Of Marxism In A Post-Marxist World, Justin Schwartz

Justin Schwartz

Just as Marx's insights into capitalism have been most strikingly vindicated by the rise of neoliberalism and the near-collapse of the world economy, Marxism as social movement has become bereft of support. Is there any point in people who find Marx's analysis useful in clinging to the term "Marxism" - which Marx himself rejected -- at time when self-identified Marxist organizations and societies have collapsed or renounced the identification, and Marxism own working class constituency rejects the term? I set aside bad reasons to give on "Marxism," such as that the theory is purportedly refuted, that its adoption leads necessarily …
