The author shows with pooled OLS estimations based on transport margins from international social accounting data that investments in improved road infrastructure have the potential to significantly reduce transport costs. However, this result can only be clearly confirmed for industrial...

We show with the aid of pooled OLS estimations that investments in improved road infrastructure have the potential to signi cantly reduce transport costs. However, this result can only be clearly con rmed for industrial countries and is of primary importance for production and transportation of...

Over the last two decades the share of national income which accrues to labour has followed a marked downward trend across a host of industrialised countries. This paper attempts to assess the importance of several potential causes of this phenomenon. We investigate compositional effects, the...

This study examines the relevance of Brazilian domestic transportation and logistics processes for agricultural bulk exports in terms of costs and CO2 emissions between farm gate and seaport, using the example of soybeans. To estimate the impact of logistics and transportation on the...

This paper examines if international trade can reduce total welfare in an international oligopoly with differentiated goods. We show that welfare is a U-shaped function in the transport cost as long as trade occurs in equilibrium. With a Cournot duopoly trade can reduce welfare compared to...

Recent empirical evidence suggests that prices for some goods and services are higher in larger markets. This paper provides a demand-side explanation for this phenomenon when firms can choose how much to differentiate their products in a model of monopolistic competition with horizontal product...

The literature on trade facilitation has mostly focused on implications for trade volumes. However, recent theoretical contributions have emphasized that trade costs - such as transaction costs related to cross-border trade procedures - affect both the traded volumes of "old" goods (the...
