Recycling waste from used goods can substitute for scarce raw materials and reduce resource dependence. This paper presents a model of waste collection, recycling and final goods production using raw and recycled materials. Non-recycled waste must be safely stored by landfill to avoid...

This paper suggests a quantifiable multi-sector-multi-country economic model of goods and services production and consumption. It calibrates overall (variable and fixed) costs to market-specific sales by sector and decomposes these costs into observable and unobservable components. In an...

This paper shows that market concentration is positively related to outsourcing activities in a framework of Cournot competition with strategic outsourcing in a first stage. The theoretical priors are confirmed by rank correlation coefficients between the intermediate goods import intensity and...

The overwhelming importance of multinational activities as well as the coexistence of exporters and multinationals within the developed countries demand for theoretical models which provide a convincing explanation of simultaneous two-way trade and horizontal multinational activities. We present...

This paper assesses whether the sensitivity of bilateral trade volumes to various trade cost factors is constant or varies across countries. It utilizes a random coeffcients model and analyses a cross-sectional sample of bilateral trade data for 96 countries in 2005. We expect the elasticity of...

We set up a trade model with heterogeneous firms and a worker population that is heterogeneous in two dimensions: workers are either skilled or unskilled, and within each skill category there is a continuum of abilities. Workers with high abilities, both skilled and unskilled, are matched to...

We use firm-level data for 15 countries and 13 manufacturing sectors to estimate firm-level productivity parameters and to establish representative country-sector-specific empirical productivity distributions. We use these distributions against the backdrop of multi-sector versions of the models...

This paper assesses the role of a larger degree of common language use between the populations of two countries on the so-called extensive product margin of trade. We focus on the overlap of products exported or imported between any pair of countries. The results suggest that the effect of...

Since the revival of the gravity literature in the early nineties most work has been done with cross-section data. Just a few more recent contributions made use of panel data. So far that research left open the question whether to treat time and country effects as random or fixed. This note...
