The two models of international trade with developed factor markets -- Heckscher-Ohlin and Specific Factors -- both suffer significant defects. For example, their predictions about the patterns of domestic production and international trade are for the most part either indeterminate or uselessly...

Each worker brings a bundle of skills to the workplace, for example, quantitative and communication skills. Since employers must take this bundle as a package deal, they choose workers with just the right mix of skills. We show that international differences in the distribution of worker skill...

The Canada-U.S. Free Trade Agreement (FTA) provides a unique window on the effects of trade liberalization. It was an unusually clean trade policy exercise in that it was not bundled into a larger package of macroeconomic or market reforms. This paper uses the 1989-96 Canadian FTA experience to...

This paper makes three observations about international trade and immigration. (i)" Borjas has argued that immigration may yield a net social benefit even though it hurts those less-skilled workers who directly compete with immigrants. I show that this closed-economy" argument unravels when...

Artificial Intelligence is a powerful new technology that will likely have large impacts on the size, direction and composition of international trade flows. Yet almost nothing is known empirically about this. One AI-enabled set of services that can be tracked resides in the palm of our hands:...

Products often bundle together many functions e.g., smartphones. The firm develops the big idea (which functions to bundle) and then chooses one supplier per function. We develop a model featuring holdup in which the firm's bargaining power declines in the number of suppliers. Greater scope as...

To illustrate how small the effects are, suppose that over the next nine years all of inshoring and offshore outsourcing grew at rates experienced during 1996-2005 in business, professional and technical services i.e., in segments where China and India have been particularly strong. Then workers...

We weigh into the debate about whether rising productivity is ever a consequence rather than a cause of exporting. Exporting and investing to raise productivity are complimentary activities. For lower-productivity firms, incurring the fixed costs of such investments is justifiable only if...
