A Unified Growth Model for Independent Chile
This article analyzes long-term patterns of growth of the Chilean economy. Examining 200 years of data, it shows evidence in favor of using a neoclassical growth model to conduct the empirical analysis. It presents a formal analysis of structural breaks in the Chilean growth process, finding structural changes in 1929 and 1971/1981. A further analysis of the country’s economic history indicates that fiscal policy, external shocks and trade policy are plausible explanations for these breaks. When these variables are included in the empirical model, the hypothesis of no breaks during these 200 years cannot be rejected.Chile, structural breaks, growth, fiscal policies, external shocks
Bounds on Correlation Functions of Quantum Rotators
We derive a McBryan-Spencer bound to the correlation function of a
one-dimensional array of quantum rotators in the Villain approximation of the
cosine interaction. We obtain the partition function of the system in the gas
representation and establish a lower bound on the external charge correlation
function. We also discuss the possible existence of a Kosterlitz-Thouless phase
for the quantum rotator in the Villain approximation.Comment: Latex 7 page
