We show that the weak Pareto law, as used to characterize the tail behaviour of income distributions, implies regularly varying tail probabilities, but that the reverse implication does not hold. We also establish implications among other versions of the weak Pareto law.

I develop an open economy portfolio model to study how leveraged investors' wholesale funding affects the international transmission of shocks. Under binding borrowing limits, there is a link between the international investment positions of integrated economies as investors diversify the asset...

Equity home bias is one of the most enduring puzzles in international finance. In this paper, I start out by documenting a novel stylized fact about home bias: countries with weaker domestic institutions hold fewer foreign assets. I then explore a macroeconomic mechanism by which the presence of...

The present paper extends the literature on central bank transparency that relies on information heterogeneity among private agents in four directions. First, it adds the interest rate to the list of signals that the central bank can reveal. Second, it allows for more than one economic...

We develop a theoretical model of international trade pricing in which individual exporters and importers bargain over the transaction price and exposure to exchange rate fluctuations. We find that the choice of price and invoicing currency reflects the full market structure, including the...

This paper develops a simple model with credit rationing and endogenous default risk in which the expectation of a bailout may lead to a financial sector which is too large with respect to the the social optimum. The paper concludes with a short discussion of how this model could be used as a...

Geographical Indications (GIs) for products (Basmati rice, Champagne sparkling wine, Antigua coffee, etc.) were regulated at the international level in 1995 (WTO TRIPS Agreement, Part II, Section 3). This paper sets a general framework of analysis for GI-labeled goods, based on the modeling of a...

There has been a long debate about whether speculators are stabilizing or not. We consider a model where speculators have a stabilizing role in normal times, but may also provoke large risk panics. The very feature that makes arbitrageurs liquidity providers in normal times, namely their...

This paper constitutes an attempt to reframe and eventually deflate the ongoing 'compliance-vs.-rebalancing' debate which has permeated WTO scholarship for the last 10 years. Our main criticism concerns the substance of the entire debate. We find that scholars on both sides of the...

This paper focuses on the observed empirical relationship between fiscal rules and budget deficits, and examines whether this correlation is driven by an omitted variable, namely voter preferences. We make use of two different estimation methods to capture voter preferences in a panel of Swiss...
