| Thanks to its empirical success, the gravity approach is widely used to explain trade patterns between countries. In this article we question the simple application of this approach to product/sector-level trade on two grounds. First, we demonstrate that the traditional Armington version of gravity must be altered to properly account for the fact that sector expenditures are not strictly equal to sector productions because some trade costs are incurred outside the sector of interest. Secondly, we show empirically that collecting/using good data on sector-level trade and expenditure is extremely crucial for the quality of econometric estimations. Above all one should strictly adhere to the requirements of the theoretical frameworks in order to obtain... |

| La agricultura, la ganader??a, la manufactura textil y el comercio, como las principales actividades econ??micas de la provincia de Imbabura, han adoptado a trav??s de los per??odos hist??ricos, diferentes formas de producci??n. Esta transformaci??n, muestra pr??cticas comunitarias y formas solidarias de intercambio y relacionamiento como el trueque, esto es, el intercambio de bienes y productos en donde no interviene el dinero. Este art??culo pretende evidenciar como esta pr??ctica utilizada hace mucho tiempo atr??s, todav??a subsiste en algunos lugares de la provincia de Imbabura, especialmente en el cant??n Pimampiro. |

| Although transport costs are a key-ingredient of New Economic Geography, the transport sector is usually abstracted away from the analysis. Put differently, freight rates are taken as parametric and are not set by the market. This paper studies the relationships between transport costs, industry location, and welfare when freight rates are set by profit-maximizing carriers. We show that the demand for transport services becomes less elastic as the degree of spatial agglomeration rises, which increases carriers' market power and allows them to charge higher markups. Once it is recognized that firms and consumers are free to relocate in response to changes in transport costs, an increasing number of carriers, falling fixed or marginal costs in... |
