Credibility and Credulity: How Beliefs about Beliefs Affect Entry Incentives

In this note we investigate the infringement (entry) decision for a firm facing an incumbent patent holder with uncertain patent rights. The entrant risks a dispute by entering, resulting in either a settlement (licensing) or litigation and trial. Using the litigation model described by Priest and Klein, we investigate the expected dispute resolution and its impacts on the entrant's pre-dispute behavior. The primary contribution is to show that the entrant's expectations about the patent holder's beliefs about patent enforceability are a driving factor behind the entry decision. We develop a simple taxonomy of entrant and incumbent types to explain the entry decision.

The Economic Consequences of the Doha Round for Ireland

This paper provides a quantitative study of the economic effects of a stylised simulation of trade liberalisation for Ireland using the GTAP model. The experiment incorporates the liberalisation of agricultural, manufacturing and services trade as well as measures to improve trade facilitation. The simulation is implemented against a baseline projection of the Irish and world economy over the next decade. Overall, Ireland’s welfare will increase as a result of further trade liberalisation, with particularly strong gains from services liberalisation. The industrial liberalisation scenario also generates positive gains to Ireland, while agricultural liberalisation has a slightly negative effect on the overall economy.

The Doha Development Agenda: Mixed Prospects for Developing Countries

This paper uses the GTAP computable general equilibrium model to assess the impact of a Doha Development Agenda agreement on agricultural trade liberalisation. In particular, we examine the consequences for developing countries. The simulation incorporates further liberalisation in the areas of market access, export competition and domestic support. Most developing regions can expect strong positive results from this liberalisation, however some suffer a decrease in welfare. The magnitude of the welfare effect for these countries depends on measures to be taken by developing countries themselves, and whether they will materialise must be uncertain. The results highlight the importance of the impact of further liberalisation of the erosion of preferential trading arrangements enjoyed by developing regions.Agricultural trade liberalisation, GTAP, developing countries

Building Abstractions

The use of abstraction has been largely informal. As a consequence, it has often been difficult to see how or why a particular abstraction works. This paper attempts to help correct this trend by presenting a formal theory of abstraction. We use this theory to characterise the different types of abstraction that can be built; the different classes of abstractions we identify capture the majority of abstractions of which we are aware. We end by proposing a method for automatically building one very common type of abstraction, that used in Abstrips; our proposal is motivated by consideration of the various formal properties that such a method should possess

Agent based cooperative theory formation in pure mathematics

The HR program, Colton et al. (1999), performs theory formation in domains of pure mathematics. Given only minimal information about a domain, it invents concepts, make conjectures, proves theorems and finds counterexamples to false conjectures. We present here a multi-agent version of HR which may provide a model for how individual mathematicians perform separate investigations but communicate their results to the mathematical community, learning from others as they do. We detail the exhaustive categorisation problem to which we have applied a multi-agent approach.

HR: A System for Machine Discovery in Finite Algebras

We describe the HR concept formation program which invents mathematical definitions and conjectures in finite algebras such as group theory and ring theory. We give the methods behind and the reasons for the concept formation in HR, an evaluation of its performance in its training domain, group theory, and a look at HR in domains other than group theory

Implications of Domestic Support Disciplines for Further Agricultural Trade Liberalization

This paper employs the GTAP computable general equilibrium model and dataset to analyse the implications of domestic support reductions in the context of agricultural trade liberalisation. Three specific issues are addressed: overhang in domestic support, the accurate distinction of the boxes in the GTAP dataset and the treatment of market price support in the amber box. An extensive domestic support database is used to calculate the change in applied domestic support rates from a specified cut in bound rates, and to identify the impact on the different domestic support boxes and the required reductions in each support category. The GTAP model is extended to incorporate an explicit representation of the market price support element of the AMS. The results from these extensions of the standard database and model support the view that the impact of an agreement to reduce domestic support will be limited and lower than conventionally estimated. Results of simulations combining domestic support cuts with market access and export competition disciplines show that the effect of import tariff reductions dominate the gains from domestic support cuts once full account is taken of the issues addressed in this paper.WTO agricultural negotiations, domestic support, agricultural protection, Aggregate Measure of Support

Bargaining in the shadow of precedent: the surprising irrelevance of asymmetric stakes

We develop a model of bargaining and litigation in the context of patent licensing (or any contractual setting). Following Priest and Klein (1984) we developed a model that explicitly allows for (1) multiple parties (leading to asymmetry of stakes), (2) binding precedent, and (3) pre-dispute bargaining done in the “shadow” of precedent-setting courts. The pre-dispute bargaining creates an endogenous opportunity cost of litigation for both plaintiff and defendant; i.e., the harm is endogenous. We show that the effects of asymmetric stakes on the litigation rate and plaintiff win rate are offset by opportunity costs (forgone licensing). That is, the degree of asymmetry does not appear to substantially impact the rate of litigation or the observed win rate of plaintiffs at trial. This result is in stark contrast to the previous theoretical literature, and has implications for interpreting the empirical literature.
