Carbon price is a key variable in management and risk decisions in activities related to the burning of fossil fuels. Using innovative multivariate wavelet analysis, we study the link between carbon prices and primary and final energy prices in the time and frequency dimensions, particularly in...

We assess U.S. monetary policy across time and frequencies in the framework of the Taylor Rule (TR). First, we portray the deviations between policy interest rates and the TR-prescribed rates with a set of continuous wavelet tools, comprising the coherency, phase-diference and gain. Then, using...

We uncover evidence that the oil-macroeconomy relation changed in the past decades. We show that after the Euro adoption some countries became more similar with respect to how...

We study the effects of a hospital merger using a spatial competition framework with semialtruistic hospitals that invest in quality and expend cost-containment effort facing regulated prices. We find that the merging hospitals always reduce quality, whereas non-merging hospitals respond by...

Using a panel of 62 countries for 1973-2005, we assess the impact of financial reforms on income inequality. We find that removal of policies towards directed credit and excessively high reserve requirements, and improvements in the securities market reduce inequality.

We examine how changes in the information environment can affect real investment decisions. Using the events surrounding mandatory adoption of IFRS as exogenous shocks in information asymmetry, we find a significant increase in firms’ investment-to-price sensitivity following IFRS adoption...
