traditionally seen only in terms of trade costs, many aspects of economic integration are more naturally viewed as lowering the cost of trading information rather than goods, i.e. as reducing the extent to which learning externalities are localised. Raising learning spillovers is stabilising, so...

Most trade-and-growth studies focus on the growth effects of autarky-to-free-trade changes, rather than those of incremental liberalizations. This paper characterizes how the strength and sign of openness-and-growth links depend upon the nature and level of trade barriers. For most types of...

The new' economic geography focuses on the footloose-labor and the vertically-linked-industries models. Both are complex since they feature demand-linked and cost-linked agglomeration forces. I present a simpler model where agglomeration stems from demand-linked forces arising from endogenous...

This paper takes a step towards formalizing the theoretical interconnections among four post-Industrial Revolution phenomena - the industrialization and growth take-off of rich northern' nations, massive global income divergence, and rapid trade expansion. Specifically, we present a...

This paper has two purposes. It introduces a direct approach to policy analysis in endogenous growth models - the q-theory approach - and uses this to illustrate several new openness-and-growth links that appear when we enrich the economic content of the early trade and growth models. The...

John Ford and Alfred Hitchcock were experimental filmmakers: both believed images were more important to movies than words, and considered movies a form of entertainment. Their styles developed gradually over long careers, and both made the films that are generally considered their greatest...

Frank Lloyd Wright, Le Corbusier, and Frank Gehry were experimental architects: all worked visually, and arrived at their designs by discovering forms as they sketched. Their styles evolved gradually over long periods, and all three produced the buildings that are generally considered their...

Psychologists have not considered wisdom and creativity to be closely associated. This reflects their failure to recognize that creativity is not exclusively the result of bold discoveries by young conceptual innovators. Important advances can equally be made by older, experimental innovators....

In 1958, the French philosopher Etienne Gilson observed that "painters are related to manual laborers by a deep-rooted affinity that nothing can eliminate," because painting was the one art in which the person who conceives the work is also necessarily the person who executes it. Conceptual...
