THE RELATIONSHIP BETWEEN DEBT LEVEL AND FISCAL SUSTAINABILITY IN ORGANIZATION FOR ECONOMIC COOPERATION AND DEVELOPMENT COUNTRIES

In this article we unify the traditional approaches to testing for fiscal sustainability considering the stock‐flow system that fiscal variables configure. Our approach encompasses previous ways of testing for sustainability. The results obtained for a group of 17 Organization for Economic Cooperation and Development (OECD) countries point to weak fiscal sustainability, as well as to the existence of cointegration between deficit and debt, confirming the relevance of the stock‐flow approach. Allowing for structural breaks and multicointegration turns out to be of critical importance to assess whether the fiscal authorities apply their policies looking for sustainability and whether, simultaneously, they try to stabilize real debt target levels.

FACSGen: A Tool to Synthesize Emotional Facial Expressions Through Systematic Manipulation of Facial Action Units

To investigate the perception of emotional facial expressions, researchers rely on shared sets of photos or videos, most often generated by actor portrayals. The drawback of such standardized material is a lack of flexibility and controllability, as it does not allow the systematic parametric manipulation of specific features of facial expressions on the one hand, and of more general properties of the facial identity (age, ethnicity, gender) on the other. To remedy this problem, we developed FACSGen: a novel tool that allows the creation of realistic synthetic 3D facial stimuli, both static and dynamic, based on the Facial Action Coding System. FACSGen provides researchers with total control over facial action units, and corresponding informational cues in 3D synthetic faces. We present four studies validating both the software and the general methodology of systematically generating controlled facial expression patterns for stimulus presentation.     

Nonverbal Auditory Cues Allow Relationship Quality to be Inferred During Conversations

Differences in wage determination in the Eurozone: A challenge to the resilience of the common currency

Different developments in wages and unit labor costs across countries can reduce the synchronization of business cycles within a currency area and therefore be a potential source of asymmetric shocks and/or asymmetric response to a common shock. In this paper, we use novel econometric methods to identify differences and similarities in wage determination across Eurozone countries. Results show that wages have different determinants across euro area countries, among which two relatively distinct groups can be identified. In particular, wages in Germany, Austria, Belgium, Luxembourg, the Netherlands and Finland behave more similarly, are less sticky and respond more to macroeconomic conditions than those in the group composed of Italy, Spain, Portugal, France and Ireland. Moreover, the equilibrium wage has been affected by a structural change contemporaneous to the international financial crisis. Finally, structural reforms since the euro crisis have contributed to make labor market structures in Eurozone countries more similar, which contributed to improve the resilience of the Eurozone, but the job is not completed yet.     

Microfinance institutions and efficiency

Microfinance Institutions (MFIs) are special financial institutions. They have both a social nature and a for-profit nature. Their performance has been traditionally measured by means of financial ratios. The paper goes beyond simple financial ratios using a data envelopment analysis (DEA) approach to measure the efficiency of MFIs.
