Identification through heteroskedasticity
WebIdentification through heteroskedasticity. Time-varying variances characterize many (macroeconomic) time series and likewise may be used to identify underlying structural shocks (see, e.g., Rigobon, 2003; Sentana & Fiorentini, 2001, for discussions of this theoretical result). Web1 nov. 2003 · This paper develops a method for solving the identification problem that arises in simultaneous-equation models. It is based on the heteroskedasticity of the structural shocks. For simplicity, I consider heteroskedasticity that can be described as a two …
Identification through heteroskedasticity
Did you know?
WebIdentification through heteroskedasticity in heteroskedastic simultaneous equations models (HSEMs) is considered. The possibility that heteroskedasticity identifies the structural parameters only partially is explicitly allowed for. The asymptoticproperties of the identified parameters are derived. WebWhen interpreting the results, the inclusion of the proxy is a key advantage over traditional identification through heteroskedasticity, where a main challenge is the economic interpretation of the statistically identified shocks (Herwartz and Lütkepohl ). The restrictions on β pin-down the monetary shock in the first column of D.
Web1 jan. 2000 · In this paper, I develop a new identification method to solve the problem of simultaneous equations, based on heteroskedasticity of the structural shocks. I show that if the heteroskedasticity can be described as a two-regime process, then the system is just identified under relatively weak conditions. Identification is also discussed under more … Web30 mrt. 2000 · I show that if the heteroskedasticity can be described as a two-regime process, then the system is just identified under relatively weak conditions. …
Web15 jul. 2010 · We discuss general conditions for identification and one of the results shows that an adequate number of different levels of heteroskedasticity is sufficient to identify … Webis, therefore, to identify the two-way causal relationship in a panel of countries using “identification through heteroskedasticity” (Rigobon, 2003). There is a widespread belief in the literature and in policy circles that many countries have difficulties letting their exchange rate float and that many countries that claim to be floaters
WebThe method works by exploiting model heteroscedasticity to construct instruments using the available regressors. Some authors have considered the method in empirical applications where an endogenous regressor is binary (e.g., endogenous Diff-in-Diff or endogenous binary treatment models).
