Why are female entrepreneurs so rare? In Germany, women exhibit both a lower entry rate into and higher exit rate from self-employment. To explain this gender gap, this study estimates a structural microeconometric model of transition rates that includes a standard risk aversion parameter. Inputs into the model are the expected value and variance of earnings from self-employment and dependent employment, ...

Interest in the effects of sleeping behavior on health and performance is continuously increasing - both in research and with the general public. Ecologically valid investigations of this research topic necessitate the measurement of sleep within people's natural living contexts. We present evidence that a new approach for ambulatory accelerometry data offers a convenient, reliable, and valid measurement ...

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. ...

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 ...

This paper provides formulas for optimal top marginal tax rates when couples are taxed according to income splitting between spouses, consumption is taxed, and the skill distribution is unbounded. Optimal top marginal income tax rates are computed for Germany using a dataset that includes the tax returns of all German top taxpayers. We find that the optimal top marginal tax rate converges to about ...

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. The ...

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 ...

It is still unclear to what extent time allocation retrospectively reported in questionnaires reflects people's actual behavior. Addressing this research gap, we analyze the congruence oftime use information assessed through retrospective questionnaires and through experience sampling methodology. Participants completed standard survey questions on time allocation. In addition, a mobile-phone-based ...

This paper assesses the validity of the perception-based governance indicators used by the US Millennium Challenge Account (MCA) for aid allocation decisions. 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 ...
