Dramatic changes are occurring in the nature of international trade. Production processes
increasingly involve a sequential, vertical trading chain stretching across many countries,
with each country specializing in particular stages of a good's production sequence. We ...
Not surprisingly, big countries trade more than small countries. In this paper we use data on
shipments by 110 exporters to 59 importers in 5,000 product categories to ask: how? Do big
countries trade larger quantities of a common set of goods (the intensive margin), a larger ...
Abstract: What are the barriers that separate nations; While recent work provides intriguing
clues, we have remarkably little concrete evidence as to the nature, size, and shape of
barriers. This paper offers direct and indirect evidence on trade barriers, moving us toward ...
A large and growing share of international trade is carried on airplanes. Air cargo is many
times more expensive than maritime transport but arrives in destination markets much faster.
We model firms' choice between exporting goods using fast but expensive air cargo and ...

Abstract We test some propositions about international trade flows that are derived from
models of monopolistic competition developed by Elhanan Helpman and Paul Krugman. We
investigate whether the volume of trade between OECD countries is consistent with the ...

Abstract: A major feature of globalization has been the enormous increase in international
flows of goods and services: countries are now trading much more with each other. In this
article, the authors demonstrate the greater role vertical specialization is playing in these ...

Abstract: While the precise causes of post-war trade growth are not well understood,
declines in transport costs top the lists of usual suspects. However, there is remarkably little
systematic evidence documenting the decline. This paper provides a detailed accounting ...

Abstract: While the precise causes of postwar trade growth are not well understood, declines
in transport costs top the lists of usual suspects. However, there is remarkably little
systematic evidence documenting the decline. This paper brings to bear an eclectic mix of ...
We model demand for quality differentiated goods to derive a relationship between trade
costs and the quality composition of trade. Detailed data on traded goods' prices, quantities
and shipping costs for many importers and exporters are used to test these predictions. ...

Abstract. We examine why the gravity equation works and the implications for its use. First,
we demonstrate that the gravity equation as a statistical relationship can be generated from
a model with incomplete specialization and trade costs. Second, we analyse the ...
R Hillberry… - European Economic Review, 2008 - Elsevier
A large literature has shown that geographic frictions reduce trade, but has not clarified
precisely why. In this paper, we provide some insight into why such frictions matter by
examining what parts of trade these frictions reduce most. Using data that track ...
D Hummels, V Lugovskyy… - Journal of Development Economics, 2009 - Elsevier
Developing countries pay substantially higher transportation costs than developed nations,
which leads to less trade and perhaps lower incomes. This paper investigates price
discrimination in the shipping industry and the role it plays in determining transportation ...

Wolf demonstrates that trade within the United States appears substantially impeded by
state borders. We revisit this finding with improved data. We show that much intranational
home bias can be explained by wholesaling activity. Shipments by wholesalers are much ...
D Hummels… - The American Economic Review, 1993 - JSTOR
Countries with similar factor endowments appear to trade a great deal with one another.
Furthermore, much of this trade is in goods that are produced by the same industry. This
phenomenon, termed intraindustry trade, has motivated substantial bodies of empirical ...

We show that'home bias' in trade patterns will arise endogenously due to the co-location
decisions of intermediate and final goods producers. Our model identifies four implications
of home bias arising out of specialized industrial demands. Regions absorb different ...
Models with constant-elasticity of substitution (CES) preferences are commonly employed in
the international trade literature because they provide a tractable way to handle product
differentiation in general equilibrium. However this tractability comes at the cost of ...

SUMMARY In this paper we raise questions regarding the appropriateness of the traditional
gravity model for evaluating the existence of trade creation and trade diversion in the context
of regional trade arrangements. We demonstrate that existing methods fail to separate ...
We examine a generalized version of Flam and Helpman’ s (1987) model of vertical
differentiation that maps cross-country differences in income distributions to variations in
import variety and price distributions. The theoretical predictions are examined and ...

It is common when analyzing the effects of trade liberalization to take other trade frictions as
given. This is consistent with a modeling strategy that focuses on how and where goods are
produced, but ignores the manner in which they are shipped from location to location. But ...
