The thermodynamic stability of structural isomers of C24, C26, C28 and C32, including fullerenes, is studied using density functional and quantum Monte Carlo methods. The energetic ordering of the different isomers depends sensitively on the treatment of electron correlation. Fixed-node diffusion quantum Monte Carlo calculations predict that a C24 isomer is the smallest stable graphitic fragmen...

We estimate and test the conditional version of an International Capital Asset Pricing Model using a parsimonious multivariate GARCH process. Since our approach is fully parametric, we can recover any quantity that is a function of the first two conditional moments. Our findings strongly support a model which includes both market and foreign exchange risk. However, both sources of risk are only...

We implement novel tests of general relative purchasing power parity (PPP), defined as a long-run unit elasticity of the nominal exchange rate with respect to relative national prices, allowing for potentially permanent real exchange rate shocks. The finite-sample properties of the estimators used are analyzed through Monte Carlo analysis, allowing for country heterogeneity, cross-sectional dep...

A structural vector autoregressive (SVAR) model of real equity prices in Australia is specified to contain common shocks in international equity markets and domestic shocks in Australian financial and goods markets. Common shocks are identified through the long-run comovements of international equity markets, resulting in the model being characterized as having more shocks than variables. The e...

Kamu borçlarında meydana gelen artışlar, büyüme, bütçe açığı, enflasyon gibi pek çok ekonomik değişken üzerinde olumsuz etkilere yol açabilmektedir. Özellikle ortaya çıkan belirsizliklerle birlikte borçlanmanın çıkaracağı artan maliyet, faiz oranlarının yükselmesine açmaktadır. Öte yandan oranları yatırım oranlarını azaltarak büyüme azalmasına Bu nedenle kamu borcu, uzun dönem kanalıyla ülkeler...

The link between US labor cost and price inflation has weakened notably over the past three decades. In this paper we document decline analyse potential contributing factors. We consider four important trends that have shaped economy of late: (i) improved anchoring expectations; (ii) changing constellation shocks hitting economy; (iii) increased trade integration (iv) rising firm market power. ...
