We show that asymmetric persistence induces ARCH effects, but the LM-ARCH test has power against it. On the other hand, the test for asymmetric dynamics proposed by Koenker and Xiao (2004) has correct size under the presence of ARCH errors. These results suggest that the LM-ARCH and the...

The presence of deterministic or stochastic trend in US GDP has been a continuing debate in the literature of macroeconomics. Ben-David and Papell (1995) found evidence in favour of trend stationarity using the secular sample of Maddison (1991). More recently, Murray and Nelson (2000) correctly...

This paper investigates the role of Regional Trade Agreements (RTAs) on bilateral international migration. By increasing the information on the potential destination country, RTAs may favour bilateral migration flows among member countries. Building on the gravity model for migration by Anderson...

This article develops nonparametric tests of independence between two stochastic processes satisfying β-mixing conditions. The testing strategy boils down to gauging the closeness between the joint and the product of the marginal stationary densities. For that purpose, we take advantage of a...
