ESTIMATION ISSUES IN SINGLE COMMODITY GRAVITY TRADE MODELS
Prehn, Soren; Brummer, Bernhard - 2011
Recently gravity trade models are applied to disaggregated trade data. Here many zeros arecharacteristic. In the presence of excess zeros usual Poisson Pseudo Maximum Likelihood(PPML) is still consistent, the variance covariance matrix however is invalid. Correcteconomic interpretation however...
