Antitrust, Innovation, and Uncertain Property Rights: Some Practical Considerations

The intersection of antitrust and intellectual property circumscribes two century-long debates. The first pertains to questions about how antitrust law and intellectual property law interact, and the second pertains to questions about how parties can exploit property rights, including intellectual property rights, to exclude competitors. This iBrief finesses these questions and turns to practical considerations about how innovation and intellectual property can impinge antitrust enforcement. This iBrief develops two propositions. First, although collaborative research and development has often been and remains unwittingly misunderstood, what is understood about it is consistent with the long- standing observation that antitrust has rarely interfered with collaborative ventures. Second, shifting focus from “intellectual property rights” to “uncertain property rights” makes it easier to understand what innovation and intellectual property imply for enforcement processes. Both intellectual property and tangible assets imply the same processes, but the boundaries of intellectual properties may be uncertain and may, in turn, allow parties to game enforcement processes in ways that would not be feasible in antitrust matters that principally feature tangible assets. Even so, uncertain property rights might not frustrate enforcement processes as the antitrust authorities may yet be able to factor parties’ strategic behaviors into the design of antitrust remedies

Organization, Control and the Single Entity Defense in Antitrust

Since at least the 1930's economists have puzzled over how to delineate the boundaries of the firm. With the advent of antitrust legislation in 1890, courts have been pressed to consider what constitute conspiracies between corporate entities to restrain commerce. By the 1940's, courts started to characterize conspiracies by sorting out what they are not — specifically, by extending the status of "single entity" to certain types of business arrangements. Both efforts in economics and in the law to sort out what constitutes a "firm" or "single entity" have focused on "control." A difficulty is that neither the law nor economics offer an operationally significant concept of control. Even so, both law and economics contribute concepts other than control that provide a way of understanding economic organization. These concepts — control rights, adaptation, delegation, and renegotiation — suggests how one can subsume the sometimes confusing array of single entity tests proposed in the case law within a two-stage sequence of tests.

Robot docking using mixtures of Gaussians

This paper applies the Mixture of Gaussians probabilistic model, combined with Expectation Maximization optimization to the task of summarizing three dimensionals range data for the mobile robot. This provides a flexible way of dealing with uncertainties in sensor information, and allows the introduction of prior knowledge into low-level perception modules. Problems with the basic approach were solved in several ways: the mixture of Gaussians was reparameterized to reflect the types of objects expected in the scene, and priors on model parameters were included in the optimization process. Both approaches force the optimization to find 'interesting' objects, given the sensor and object characteristics. A higher level classifier was used to interpret the results provided by the model, and to reject spurious solutions

Seeing the music in their hands: How conductors' depictions shape the music

Depiction is a way of ‘showing’ meaning through certain gestures or demonstrations. Conductors often use depiction, including multimodal depiction, as well as descriptive talk, to convey meaning to their choirs. This paper considers four short extracts from choir rehearsals with different conductors, to show how they combine description and depiction, including vocal models, facial expressions, metaphoric and iconic gestures and body language to communicate about music, specifically here as part of the activity of modelling

Genomic homogeneity in fibrolamellar carcinomas

Background-Fibrolamellar carcinoma (FLC) is a variant of hepatocellular carcinoma (HCC) with distinctive clinical and histological features. To date there have been few studies on the genotypic aspects of FLC and no previous attempts have been made to use the arbitrarily primed-polymerase chain reaction (AF-FCR) technique to detect genetic alterations in this disease.Aim-The aim of this study was to assess the degree of genomic heterogeneity of FEC using the AP-PCR technique. Methods-A fetal of 50 tissue samples of primary and metastatic FLCs from seven patients were microdissected. AP-PCR amplification of each genomic DNA sample was carried out using two arbitrary primers.Results-DNA fingerprints of the primary FLCs and all their metastatic lesions (both synchronous and metachronous disease) were identical in an individual patient. The fingerprints were different between tumours of different patients. No evidence of intratumour heterogeneity was observed.Conclusions-Such genomic homogeneity in FLCs may explain their indolent growth. The absence of clonal evolution, which is present in other tumours (particularly HCCs), may explain the distinct behaviour in this tumour. The tumorigenic pathway and degree of somatic genomic changes in this disease may be less complex than in HCC

Investment Incentives and Market Power: An Experimental Analysis

We examine investment incentives and market power in an experimental market. We characterize market power as the strategic interdependence of subjects' investment decisions and output decisions. The market is designed so that investment and output decisions can be jointly characterized as strategies within a game. A Nash-Cournot equilibrium of the game provides a way of characterizing how investment incentives and market power interact. Subjects could invest in two different production technologies and could produce output to serve as many as two different demand conditions. The technologies were analogous to "baseload" capacity and "peaking" capacity in wholesale electricity markets. The Nash-Cournot benchmark constituted a good indicator of subjects' output decisions in that output cycled around the Cournot benchmark. Thus, on average, consumers extracted the surplus available to them in the equilibrium. While we do not observe Edgeworth Cycles in prices or outputs, we do see them in the producer surplus series. Producers dissipated some of the surplus they could have extracted in the equilibrium by overinvesting in peaking capacity and underinvesting in baseload capacity. Inefficient investment diminished total system efficiency, but producers' investments in total production capacity tracked the Nash-Cournot benchmark. In contrast, monopoly explanations such as collusion do not characterize the data.capacity investment, Cournot, supply function equilibrium, Edgeworth Cycles, market power, electricity markets, investment incentives

Composite Geometric Phase for Multipartite Entangled States

When an entangled state evolves under local unitaries, the entanglement in the state remains fixed. Here we show the dynamical phase acquired by an entangled state in such a scenario can always be understood as the sum of the dynamical phases of its subsystems. In contrast, the equivalent statement for the geometric phase is not generally true unless the state is separable. For an entangled state an additional term is present, the mutual geometric phase, that measures the change the additional correlations present in the entangled state make to the geometry of the state space. For $N$ qubit states we find this change can be explained solely by classical correlations for states with a Schmidt decomposition and solely by quantum correlations for W states.Comment: 4 pages, 1 figure, improved presentation, results and conclusions unchanged from v1.

Development of a flash, bang, and smoke simulation of a shell burst

A large number of experiments (cue test firings) were performed in the definition of the cue concepts and packaging configurations. A total of 344 of these experiments were recorded with instrumentation photography to allow a quantitative analysis of the smoke cloud to be made as a function of time. These analyses were predominantly made using a short test site. Supplementary long range visibility tests were conducted to insure the required 3 kilometer visibility of the smoke signature
