Estimation risk is known to have a huge impact on mean/variance (MV) optimized portfolios, which is one of the primary reasons to make standard Markowitz optimization unfeasible in practice. Several approaches to incorporate estimation risk into portfolio selection are suggested in the earlier...

This study contributes to the valuation of employee stock options (ESO) in two ways: First, a new pricing model is presented, admitting a major part of calculations to be solved in closed form. Designed with a focus on good replication of empirics, the model fits with publicly observable...

The aim of this paper is to explore the patterns of trade duration across regions and to identify its determinants. Using an extended Cox model, we evaluate the effects of country and product characteristics, as well as of trade cost variables on the duration of trade relationships from 96...

This paper analyzes the spatial interdependence of Free Trade Agreements (FTAs) in a cross-section framework using the Contagion Index proposed by Baldwin and Jaimovich (2010). A Bayesian heteroskedastic probit model is estimated, where a spatial lag is built based on the Contagion Index,...

In this paper we combine the tariff evasion analysis of Fisman and Wei (2004) with Rauch and Trindade's (2002) study of Chinese trade networks. Chinese networks are known to act as trade catalysts by enforcing contracts and providing market information. As tariff evasion occurs outside the law,...

This paper investigates whether preferential trade agreements (PTA) promote exports to third nations through the expansion of the extensive margin (i.e. larger number of export goods). The analysis covers 11 South-South and South-North PTAs involving 36 countries that exported to 118 different...

This paper looks into aid allocation in the response to multiple crises, focusing more specifically on the cases of concomitance between so-called 'natural' hazard/disaster and conflict situations. Over 150 natural disasters have occurred alongside complex political crises in the past seven...

A traditional argument in favor of flexible exchange rates is that they insulate output better from real shocks, because the exchange rate can adjust and stabilize demand for domestic goods through expenditure switching. This argument is weakened in a model with high foreign currency debt and...
