Purpose: In order to improve the energy utilization and achieve sustainable development, this paper integrates energy efficiency into condition-based maintenance(CBM) decision-making for two-component parallel systems. The objective is to obtain the optimal maintenance policy by minimizing total...

The influence of heterogeneous expectations on monetary policy performance has gained a lot of attention in the recent years. It proved to be an important factor that, under some circumstances, may even destabilize the economy (Massaro, 2012). This paper investigates the phenomenon of...

We create a network of bilateral correlations of changes in sovereign bond yields and individual bank equity price changes since 2000. We extract some stylized facts from this network of asset price correlations and document the clear differences in asset price correlations between safe havens...

We propose a new methodology of assessing the effects of individual institution's risk on the others and on the system as a whole. We build upon the Conditional Value-at-Risk approach, however, we introduce the explicit Granger causal linkages and we account for possible nonlinearities in the...

We study the relationship between net trade credit and firms' investment levels, focusing on financially distressed firms. First, we introduce a theoretical model to predict the role played by net trade credit as a coordination device differentiating firms by their degree of financial distress....

We develop a sovereign default risk index using natural language processing techniques and 10 million news articles covering over 100 countries. The index is a high-frequency measure of countries' default risk, particularly for those lacking market-based measures: it correlates with sovereign...
