This study examines the nature of competition between the two leading brands of a national small size market by estimating shortand long-term competitive reactions via a Structural VAR (SVAR) model. The primary findings indicate how the two competitors react, which marketing instruments are used, and when competitive reactions affect crossand own-sales. The empirical results suggest that compet...

Under specific parametric assumptions, an n−variable structural vector auto-regression (SVAR) can be identified (up to n! shock orderings) via heteroskedasticity of the structural shocks (Rigobon, 2003, Sentana & Fiorentini, 2001). I show that misspecification of the heteroskedasticity process can bias results derived from these identification schemes. I propose a different method that identifi...

This paper investigates changes in the conduct of U.S. monetary policy. Monetary policy is modeled in the context of the Bernanke-Mihov (1998) structural VAR (SVAR) extended to allow explicitly for the Fed’s forward looking behavior. This is achieved by including its realtime forecasts on in‡ation and unemployment (the “Greenbook” forecasts). Stability tests that exploit the SVAR identifying re...

The monotypic genera Epiplagiops Blanchard, 1943 and Tetragrapha Brauer and Bergenstamm, 1891 are revised. Both are invalidated and synonymized with Chetogena Rondani, 1856. Their type-species, Epiplagiops littoralis Blanchard, 1943 and Tetragrapha tessellata Brauer and Bergenstamm, 1891, are studied, redescribed, illustrated, and transferred to Chetogena. A lectotype is designated for T. tesse...

Pilobalia (Pimeliinae: Nycteliini) is an endemic genus of the Andean region South America, distributed in Peru, Bolivia, Chile and Argentina. The objective this work was to update knowledge Peruvian territory, providing updated checklist species new distribution records. From examination around 580 specimens, a total 26 two subspecies are recorded for incorporating that were not previously reco...
