This paper presents an overview of the procedures that are involved in prediction with machine learning models with special emphasis on deep learning. We study suitable objective functions for prediction in high-dimensional settings and discuss the role of regularization methods in order to...

How do exporters expand their product scope and geographical presence? We argue that new exporters are uncertain about their profitability in different countries and products, but learn it as they start to export. As a consequence, exporters add products and countries sequentially, in an...

How do exporters enter and expand their product scope and geographical presence? We show that exporters add products and countries sequentially, in an interdependent process. This process can be explained by a mechanism where new exporters are uncertain about the profitability of their products...

Thus, it is the possibility of profitable expansion at both the intensive and extensive margins what makes incurring the sunk costs to enter a single foreign market worthwhile despite the high failure rates. Using a census of Argentinean firm-level manufacturing exports from 2002 to 2007, we...

Many countries are looking to their export sectors as a source of future growth, but how do domestic companies make a success of selling their output abroad? Research by Emanuel Ornelas and colleagues finds evidence of 'sequential exporting' - firms experimenting in nearby foreign markets before...
