Globalisation, has intensified the demand preference for quality labour, that embodies more knowledge and competency/skill to maximise the production in one hand, and it has also changed the life style and consumption behavior of the society on the other. As a consequence, this has led to...

We analyze the spatial interaction among regions in North America and in Western Europe. We use a gravity model extended by a spatial correlation structures where data allows to evaluate the level of impact and the length of the spatial tail. This allows us to address to effects external to the...

This paper studies an intermediated market operated by middlemen with high inventory holdings. I present a directed search model in which middlemen are less likely to experience a stockout because they have the advantage of inventory capacity, relative to other sellers. The model explains why...

This paper utilizes a unique trade database that includes all provincial, state and cross-border trade in North America. The analysis shows that the border effect, although present, is not as strong as once thought and appears to be largely related to tariff and non-tariff based barriers to...

Does national market size matter for industrial structure? This has been suggested by theoretical work on quot;home marketquot;effects, as in Krugman (1980, 1995). In this paper, I show that what previously was regarded as an assumption of convenience transport costs only for the differentiated...

This paper estimates the agglomeration benefits that arise from vertical linkages between firms. The analysis is based on international trade and economic geography theory developed by Krugman and Venables (1995). We identify the agglomeration benefits off the spatial variation in firm-level...

We use detailed information from U.S. consumers' credit card purchases to provide the first large scale description of the geography of consumption. We find that consumers' mobility is quite limited and document significant heterogeneity in the importance of gravity across sectors. We develop a...

In the late 1990s, as economists looked back the development period in Africa since 1970s, they put forward the notion “African growth tragedy” , meaning that Africa's poor growth and resulting low income is associated with low schooling, political instability, underdeveloped financial...

Drawing on insights of current and past editors of top economics and finance journals, we provide guidelines for reviewers in preparing referee reports and cover letters for journals. Peer review is fundamental to the progress of science and we believe that fundamental changes in reviewing...

Using data on academic citations, career and educational histories of mathematicians, and disaggregated distance data for the world's top 1000 math departments, we study how geography and ties affect knowledge flows among scholars. The ties we consider are coauthorship, past colocation,...
