We present and test a model relating a firm's idiosyncratic cost, its exporting status, and the volatilities of its domestic and export sales. In prior models of trade, supply costs for domestic and exports were linear and thus additively separable. We introduce a nonlinear cost function in...

In this paper, we examine an innovative postal export regime that involves both a streamlining of export procedures and provision of intermediation services to investigate how firms' react to changing trade costs and whether and how these firms learn. In so doing, we use a unique dataset that...

We examine transaction-level Peruvian import data to show that firms are subject to significant costs of port-of-entry delays. At the transaction level, we observe the time it takes a shipment to clear each step in the entry process. Our theory shows conditions under which observed entry times...

Trade facilitation policies intend to simplify administrative processes and accelerate the handling of shipments across borders. Recent research shows that these policies have substantial effects on trade flows. In this chapter, we discuss what the existing evidence for trade implies for the...

Trade facilitation policy focuses on accelerated and transparent shipment processing to reduce trade costs. A common measure to evaluate processing frictions is the time it takes to import. In this paper we translate import processing times to costs. Our theory considers that shipment processing...

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 slow but cheap ocean...
