and this is a problem when estimating log-linear gravity equations. This has caused many researchers to either ignore the zero trade flows or to replace the zero with a small positive number. Both of these actions bias the resulting parameter estimates of the gravity equation. In this study we...

In the mid-2000’s, Goldman Sachs identified two groups of emerging economies known as the BRICs and the Next-11. Primarily selected on the basis of having large populations, these countries were heralded as the growth centres of the future with the potential to stimulate increased demand for a...

Until two years ago, most citizens of Canada, the United States and Mexico experienced terrorism as a distant reality viewed from the safety of their living rooms. Today, North Americans encounter constant reminders of the aggravation and economic costs imposed on them by the now real threat of...

When analyzing bilateral trade flow data, zero trade flows are quite common and problematic when a gravity equation is estimated with a log-linear functional form. This has caused many researchers to either ignore the zero trade flows or to replace zero with a small positive number. Both of...
