Maximum residue levels (MRLs) regulations in plant products can create unnecessary trade barriers on one hand and enhance demand via risk mitigation or quality assurance on the other. We stipulate a generalized gravity equation model to disentangle the effects of MRLs on the import demand and...

We provide an ex-post econometric examination of the harmonization and tightening of the EU Maximum Residues Limit (MRL) on aflatoxins in 2002 and its impact on African exports of groundnut products. We show that the MRL set by the EU has no significant trade impact on groundnut exports from...

Domestic technical measures such as SPS and TBTs can enhance import demand via information disclosure and quality improvement, or hamper foreign export supply via imposing sizeable compliance costs, or both. The traditional gravity equation model estimates the net effect of these measures on...

We provide an ex post econometric examination of the harmonisation and tightening of the EU maximum residue limit (MRL) on aflatoxins in 2002, and its impact on African exports of groundnut products. We find no evidence of the EU MRL having a significant negative trade impact on these groundnut...

Replaced with revised version of paper 07/02/10.

This study revisits the well-known finding in the finance literature that trading is hazardous. Our analysis of data from China shows that stock trading in general hurts investment return, but it reduces the risk (volatility) of the investment. Furthermore, trading has an inverted u-shape impact...
