    Implications of Mandatory Registration of Mobile Phone Users in Africa

    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. However, markets may be increasingly saturated and new regulations introduced across Africa could also have a negative impact on future growth. Since 2006, the majority of countries ...

    Liquidity Constraints and the Permanent Income Hypothesis: Pseudo Panel Estimation with German Consumption Survey Data

    This paper empirically investigates the relevance of liquidity constraints and excess sensitivity in intertemporal household consumption. Using a pseudo panel that has been constructed on rich German consumption survey data, we estimate the consumption responses to permanent and transitory income shocks, as well as the presence of excess sensitivity to anticipated income changes. A switching regression ...

    Does Consumption Decline at Retirement? Evidence from Repeated Cross-Section Data for Germany

    The life-cycle hypothesis implies that consumption would not decline at retirement. However, several studies found relevant declines in food consumption after retirement for the United States. Others concluded that this contradiction of the life-cycle hypothesis is solved by allowing for broader measures of consumption than food. Using repeated cross-section data for Germany, this paper analyzes the ...

    Income Distribution: An Important Factor for Economic Forecasts

    The development of private consumption is a crucial factor in compiling macroeconomic projections as part of national accounts. Household savings also play an important role as an explanatory variable for consumer development, since private households must decide whether to spend their incomes on consumption or saving. The estimated savings rate in DIW Berlin's economic projections can be improved ...

    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 ...

    Unemployment and Portfolio Choice: Does Persistence Matter?

    Households can rely on private savings or on public unemployment insurance to hedge against the risk of becoming unemployed. These hedging mechanisms are used differently across countries. In this paper, we use a life cycle model to study the effects of unemployment on the portfolio choice of households in the US and in Germany. We distinguish short- and long-term unemployment and find that, in case ...
