Sub-Saharan Africa ranks among the top regions in terms of growth in the number of mobile phone users. The success of mobile telephony is attributed to the opening of markets for private players and lenient regulatory policy.

There is some research on personal reasons for saving money in the economic sciences. However, not much is known about the age differences of saving motives. In this vein, the future time perspective (FTP) is known to play a critical role for motivation across the life span. In this study, we introduce a new Saving Motive Inventory (SMI), which also covers saving goals after retirement. Furthermore, ...

This paper explores welfare dynamics among households in rural Mozambique. Using household panel data, we test whether an asset-based poverty trap exists. Findings indicate that all rural households converge to one stable equilibrium in the medium term, which is close to the poverty line. This may indicate that households in rural Mozambique are collectively trapped in generalized underdevelopment. ...

By conducting Explanatory and Confirmatory Factor Analysis of data from 1996 to 2009, we find that although the MCA purports to measure seven distinct dimensions of governance, only two discrete underlying dimensions, the perceived "participatory ...

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 ...

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 ...
