Baumol's (1967) model of 'unbalanced growth' yields a supply-side explanation for the 'cost explosion' in health care. Applying a testing strategy suggested by Hartwig (2008), a sprawling literature affirms that the 'Baumol effect' has both a statistically and economically significant impact on...

Gold is a globally traded asset and held in large quantities by investors and central banks. Since there is no established model to assess if the price of gold is overvalued or undervalued, we propose a relative valuation framework based on gold price ratios and focus on potential drivers of...

This study adopts a copula wavelet approach to analyze dynamics of the gold price against bonds, stocks and exchange rates based on disaggregation of the underlying relationships across different frequencies. We also examine whether gold prices are directly affected by changes in uncertainty....

The objective of this paper is to provide an axiomatic foundation to the concept of ecological footprint indices. For this purpose, we propose five axioms representing general properties which any ecological footprint measure should fulfill. It can be shown that there exists a unique index which...
