The Strategic Use of Private Quality Standards in Food Supply Chains

We explore the strategic role of private quality standards in food supply chains. Considering two symmetric retailers that are exclusively supplied by a finite number of producers and endogenizing the suppliers' delivery choice, we show that there exist two asymmetric equilibria in the retailers' quality requirements. Our results reveal that the retailers use private quality standards to improve their ...

Sovereign Risk Premiums in the European Government Bond Market

This paper provides a study of bond yield differentials among EU government bonds on the basis of a unique data set of issue spreads in the US and DM (Euro) bond market between 1993 and 2009. Interest differentials between bonds issued by EU countries and Germany or the USA contain risk premiums which increase with fiscal imbalances and depend negatively on the issuer's relative bond market size.

Angst und Ärger: zur Relevanz emotionaler Dimensionen sozialer Ungleichheit

Soziologische Theorien postulieren seit langem Zusammenhänge zwischen sozialer Ungleichheit. - und dem Empfinden von Emotionen. Der Vielfalt theoretischer Arbeiten steht jedoch ein Mangel an empirischen Studien gegenüber, insbesondere mit Blick auf die präzise Erfassung von Emotionen. Aus diesem Grund prüfen wir empirisch die Zusammenhänge zwischen Indikatoren sozialer Ungleichheit und der Häufigkeit ...

Who Gives Aid to Whom and When? Aid Accelerations, Shocks and Policies

We address the pitfalls of averaging by exploiting the longitudinal variation in aid to identify sudden and sharp increases in aid flows. Focusing on specific events, we testif aid accelerations correspond to policies and shocks in the recipient country. We find that positive regime changes and wars are significant predictors of aid accelerations. The results also suggest the presence of aid spill-overs, ...

Assessing the Real-Time Informational Content of Macroeconomic Data Releases for Now-/Forecasting GDP: Evidence for Switzerland

This study utilizes the dynamic factor model of Giannone et al. (2008) in order to make now-/ forecasts of GDP quarter-on-quarter growth rate in Switzerland. It also assesses the informational content of macroeconomic data releases for forecasting of the Swiss GDP. We find that the factor model offers a substantial improvement in forecast accuracy of GDP growth rate compared to a benchmark naive constant-growth ...

A Household Study of Self-Regulation in Children: Intergenerational Links and Maternal Antecedents

Delay of gratification (DoG) and delay discounting (DD) are behavioral measures of self-regulation and impulsivity. Whereas DoG refers to the postponement of gratification, DD involves the devaluation of a reward over time. Previous studies have demonstrated associations between paternal self-control, paternal personality traits, parenting styles, maternal intelligence, and children's self-regulation. ...

Crude Oil Market Power: A Shift in Recent Years?

We investigate the exertion of market power in the global crude oil market over the past years. Recognizing the difficulty of identifying market power in the crude oil market by empirical studies, we propose a numerical partial equilibrium model formulated as a mixed complementarity problem. Our approach allows for strategic behavior in a Nash-Cournot market, a Stackelberg leader-follower game, an ...
