The stability of the financial system at higher loss levels is either characterized by asymptotic dependence or asymptotic independence. If asymptotically independent, the dependency, when present, eventually dies out completely at the more extreme quantiles, as in case of the multivariate...

There are various importance sampling schemes to estimate rare event probabilities in Markovian systems such as Markovian reliability models and Jackson networks. In this work, we present a general state dependent importance sampling method which partitions the state space and applies the...

This paper surveys work on dynamic heterogeneous agent models (HAMs) in economics and finance. Emphasis is given to simple models that, at least to some extent, are tractable by analytic methods in combination with computational tools. Most of these models are behavioral models with boundedly...

These notes review two simple heterogeneous agent models in economics and finance. The first is a cobweb model with rational versus naive agents introduced in Brock and Hommes (1997). The second is an asset pricing model with fundamentalists versus technical traders introduced in Brock and...

We develop a Heckscher-Ohlin-Ramsey model, combining dual techniques with classic geometric techniques fromtrade theory. This framework is used to explore the long-run generalequilibrium effects of regional integration (preferential trade agreements). Emphasis is placed on positivemechanics...

Today’s global world is characterized not only by a high volume ofinternational trade and foreign investment relativeto national income, but also by a changed composition of that tradetowards a greater fraction of trade in inputs andcapital goods and outsourcing of production.. Emphasized is...

Using a comprehensive international trade data set we investigate empirical regularities (known as Zipf’s Law or the rank-size rule) for the distribution of the interaction between countries as measured by revealed comparative advantage. Using the recently developed estimator by Gabaix and...

Most of the large tariff reductions achieved in multilateral tradenegotiations have involved tariff-cutting formulas such as the Swissformula. However, wide variations in initial tariff rates between activeparticipants call for new approaches under the Doha Development Agenda.This paper surveys...

In a world with increasingly integrated global supply chains, trade policy targeting upstream products has unintended consequences on their downstream industries. In this paper, we examine whether protection granted to intermediate manufacturers leads to petition for protection by their...
