Increasing-returns-to-scale imperfect competition trade models predict a more than proportionate relationship between the larger country's share in world endowments and its share in producing firms: the so called home market effect (HME). While this result plays a key role in empirical testing,...

The Hodrick-Prescott (HP) method is a popular smoothing method for economic time series to get a smooth or long-term component of stationary series like growth rates. We show that the HP smoother can be viewed as a Bayesian linear model with a strong prior using differencing matrices for the...

In the two-country Melitz (2003) model, unilateral trade liberalization is often cast as a reduction of iceberg transportation costs and wages are determined by a linear outside sector. We show that welfare results reverse when wages adjust and trade frictions are revenue-generating tariffs. --...

Growth rate data that are collected incompletely in cross-sections is a quite frequent problem. Chow and Lin (1971) have developed a method for predicting unobserved disaggregated time series and we propose an extension of the procedure for completing cross-sectional growth rates similar to the...

Estimators of spatial autoregressive (SAR) models depend in a highly non-linear way on the spatial correlation parameter and least squares (LS) estimators cannot be computed in closed form. We first compare two simple LS estimators by distance and covariance properties and then we study the...

In this paper, we develop a theoretical model that provides an additional explanation for the forest transition based on a trade liberalisation scenario. Furthermore, in contrast with most explanations, in which the forest transition can only take place at a local level at the expense of other...

Arkolakis, Costinot and Rodriguez-Clare (ACR, 2012) prove that, conditional on the change in openness, the welfare gains from foreign trade reforms are quantitatively identical across single-sector trade models with radically different micro-foundations. We generalize this result to domestic and...
