Abstract
The focus is on cross-sectional dependence in panel trade flow models. We propose alternative specifications for modeling time-invariant factors such as sociocultural indicator variables, e.g., common language and currency. These are typically treated as a source of heterogeneity that is eliminated using fixed effects transformations, but we find evidence of cross-sectional dependence after eliminating country-specific and time-specific effects. These findings suggest use of alternative simultaneous dependence model specifications that accommodate cross-sectional dependence, which we set forth along with Bayesian estimation methods. Ignoring cross-sectional dependence implies biased estimates from panel trade flow models that rely on fixed effects.

Notes
We deal only with the case where the number of importing and exporting countries is the same.
We exclude exports from country i to itself, which would be on the main diagonal of the trade flow matrix, since we have no information on intra-country flows, resulting in \(N-1\).
We do not introduce an intercept vector and associated parameter since use of the within transformation to eliminate fixed effects precludes an intercept.
A value of −1 is often used in practice as this ensures that the matrix inverse \((I_{(N-1)T} - \rho (I_T \otimes W_c))^{-1}\) exists. This has the advantage that we do not have to calculate the minimum eigenvalue of \(W_c\) which changes as a function of the values taken by \(\gamma\).
In the case of maximum likelihood estimation, parameters (say 1000) are drawn from a normal distribution using the mean estimates and estimated covariance matrix based on a numerical or analytical Hessian.
Note also that we pre-compute My prior to MCMC sampling.
See Debarsy and LeSage (2018) for a discussion of the reversible jump nature of this procedure.
Specifically, \(T_1 = y' M' My\), \(T_2 = y' M' Z\), \(T_3 = Z' M y\), \(T_4 =Z' Z\) can be calculated since they consist of known quantities (sample data), so the quadratic forms are: \(e'e = \omega (\Gamma )' T_1 \omega (\Gamma ) - \omega (\Gamma )' T_2 \delta - \delta ' T_3 \omega (\Gamma ) + \delta ' T_4 \delta\). As noted, \(\omega (\Gamma )\) indicates that \(\omega (\Gamma )' = \left( \begin{array}{ccccc} 1&-\rho \gamma _1&-\rho \gamma _2&\cdots&-\rho \gamma _L \end{array} \right)\), where the parameter \(\rho\) is conditioned on (fixed).
In addition, we eliminated countries from our sample that had one or more zero rows in any of the five weight matrices. As noted earlier, this is necessary to ensure that the matrix \(W_c\) does not contain zero rows, when we allow individual \(\gamma _{\ell }, \ell = 1,\ldots ,L\) parameters to take values of zero. This resulted in a few countries such as South Korea and Japan for which data were available to be excluded from our sample.
Technically, although we allow for the open interval \((0< \gamma < 1)\), we consider a lower 0.05 value above 0.01 for the MCMC draws to be nonzero.
