Summary Mirror data are observations of bilateral variables such as trade from one country to another, reported by both countries. The efficient estimation of a bilateral variable from its mirror data, for example when compiling consistent international trade statistics, requires information...

This paper studies the model equation YT = [lambda]YT - 1 + [alpha]0XT + [alpha]1XT - 1 and its error-correction equivalent as a temporal aggregate of an underlying true equation in continuous time. Given a stylized fact about [alpha]0 / [alpha]1 we find that...

Simultaneouseconometric models may contain pairs of complementary inequalities. It is discussed how to reformulate such models and solve them with econometric software which can handle only equalities. Two approaches are applied: the normal map representation and the Fischer-Burmeister NCP...
