Sunspots and Cycles: A Test of Causation

Are causal relationships sensitive to causality tests?

“…Similarly, the results indicate the absence of causal flow between SC and A P and between SC and PI. This is contrary to the recent findings of Sheehan and Grieves (1982). Using a Granger test, they have found a causal flow from both GNP and prices to the sunspot cycles.…”

“…The data sources are similar to those used in Sheehan and Grieves (1982) although the sample period is different. Annual data on real US G N P ( Y ) and value of agricultural production (AP) are obtained from Kendrick …”

“…Hence the argument of causal flow from sunspots to business cycles does not logically follow. In a recent article, Sheehan and Grieves (1982) used Grangercausality test to investigate empirically the causal relationship between these two variables. Their evidence suggests that the US economy has a significant impact on the sun but that sunspots have no influence on the economy.…”

Corruption in Transition Economies: Cause or Effect?

“…While the methodology suggested by Granger (1969) establishes causality in the broadest sense of the term, the application of the methodology has ranged from causality of sun spots and economic growth (where Sheehan and Grieves (1982) show that economic growth Granger cause sun spots) to the timeless question of which came fi rst the chicken or the egg? (Thurman and Fisher (1988) show that it was the egg).…”

Análisis De La Dinámica Del Rendimiento De Precios Del Platino Mediante Modelos De Series De Tiempo

“…De acuerdo con Sheehan & Grieves (1982) la teoría económica propone que existen fuerzas que originan que dos series de tiempo de interés mantenga una relación de equilibrio donde un modelo de correlación permite obtener evidencia de la presencia de dicha relación y la interpretación de la teoría de interés relacionada, permite abstraer la dirección y el significado de la relación.…”
