This second volume of the two-volume set presents several different approaches to modeling the effects of the outcome of the Doha negotiations, and investigates why these (and other) modeling efforts produce such divergent results. By comparing and contrasting these approaches, it helps readers develop a clearer understanding of the mechanics and implications of modeling techniques, and also guides them in interpreting the relevance and accuracy of the plethora of news reports on different models.

English New Zealand research into social work experience with immigrants, refugees and asylum seekers supports international claims that a new field of practice is emerging. Migration across frontiers for social, political and economic reasons brings local social workers into contact with clients from all over the world as they struggle to settle into their new communities. Social workers in this field need to be skilled in work at all levels, micro, meso and macro. French Les recherches conduites en Nouvelle Zélande portant sur les expériences de travail social auprès des immigrants, des réfugiés et des demandeurs d'asile supportent les affirmations internationales à savoir qu'un nouveau champ de pratique est en émergence. Les migrations par-delà les frontières nationales pour des raisons sociales, politiques et économiques entraînent des contacts entre des travailleurs sociaux locaux et des clients en provenance du monde entier lorsque ceux-ci tentent de s'établir dans leurs nouvelles communautés. Les travailleurs sociaux dans ce champ de pratique doivent Átre outillés pour travailler à tous les niveaux car les cas qu'ils auront à traiter impliquent du travail à niveaux micro, méso et macro. Spanish La investigación en Nueva Zelanda sobre la experiencia del trabajo social con inmigrantes, refugiados y solicitantes de asilo apoya la creencia internacional que éste es un nuevo campo de práctica. Los movimientos migratorios por razones sociales, políticas, y económicas ponen a los trabajadores sociales locales en contacto con clientes provenientes de todo el mundo mientras éstos luchan por asentarse en sus nuevas comunidades. Los trabajadores sociales en este campo necesitan destrezas en todos los niveles, puesto que los casos frecuentemente necesitarán intervenciones en niveles micro, meso y macro.

"We present a neural network methodology for learning game-playing rules in general. Existing research suggests learning to find a Nash equilibrium in a new game is too difficult a task for a neural network, but says little about what it will do instead. We observe that a neural network trained to find Nash equilibria in a known subset of games will use self-taught rules developed endogenously when facing new games. These rules are close to payoff dominance and its best response. Our findings are consistent with existing experimental results, both in terms of subject's methodology and success rates."

We report here a summary of our recent research on the effect that the race issue, in the United States, and the immigration issue in European countries, is having on the degree of redistribution and the size of the public sector that is implemented through political competition. We model political competition as taking place on a two dimensional policy space, where the first issue is the tax rate, or the size of the public sector, and the second issue is the race or immigration issue. Our substantive conclusion is that the conservative economic agenda has been given new life in many countries because of racist and xenophobic views of polities. JEL Categories: D3, D7, H2

The CNN exit polls after the 2004 election rated 'moral values' the most important issue; next came 'jobs and the economy.' Eighty percent of the voters who rated moral values the most important issue voted for Bush while eighty percent of the voters who rated jobs and the economy the most important voted for Kerry. We study the extent to which the distribution of voter opinion on moral values influences the positions that parties take on the economic issue, which we take to be the size of the public sector, through political competition. There are at least two distinct ways this influence might occur. First, because the Republican Party is identified with a traditionalist stance on moral values, some voters who desire a large public sector may nevertheless vote Republican because traditionalist morality is important for them. This we call the policy bundle effect. Second, it may be the case that those who subscribe to a traditionalist morality take economic conservatism to be part of that view, in the sense that they view the state as, for instance, usurping the role of the individual and/or family. We call this effect the moral Puritanism effect. Thus economic conservatism in the US may be politically strengthened by moral traditionalism because the Republican Party links the two issues (policy bundle) or because moral traditionalists in the US are anti-statist (in the Puritan sense). Our analysis will enable us to predict how equilibrium policies proposed by Democratic and Republican Parties would change if all voters had the same view on the moral-values issue, and we will decompose these changes into the aforementioned two effects.

Abstract In theoretical literature it is common to make the assumption that in a multi‐country, multi‐good world, the direction of trade (import and export by commodity) is predetermined and fixed for each good for each country. We consider a simple three‐country, three‐good, pure‐exchange model with CES preferences. We compute free trade competitive equilibria, three‐country non‐cooperative Nash equilibria, and customs union equilibria for randomised parameterizations, and find that trade pattern changes between free trade and customs union equilibria in around 35% of cases.
