The failure of declining trade-related costs to be reflected in estimates of the standard gravity model of bilateral trade might be called the quot;missing globalization puzzle.quot; This puzzle is most apparent in the estimated distance coefficients found in the literature, which show no...

This study analyzes the stability of the distance coefficient values over time in the generalized gravity equation of Bergstrand (1989) using both aggregate and disaggregated trade flows among 22 OECD countries recorded for the sample period covering 1970 until 2000. We estimate the gravity...
