While much of the recent debate has focused on the question of how the substantive use of knowledge can improve the quality of policy choices, our understanding of the political use of knowledge and its effects in the policy process has remained deficient in key respects. A revised conceptualization of the political use of knowledge is introduced that emphasizes how conflicting knowledge can be used to contest given structures of policy authority. This allows the analysis to differentiate between knowledge creep and knowledge shifts as two distinct types of knowledge effects in the policy process. While knowledge creep is associated with incremental policy change within existing policy structures, knowledge shifts are linked to more fundamental policy change in situations when the structures of policy authority undergo some level of transformation.

We characterize growth equilibria and find that a balanced growth path not necessarily exists if households are subject to ad hoc borrowing constraints. Growth, inequality, and risk are positively related in our model, but we also identify a hump-shaped relationship between welfare and risk, indicating a tradeoff relationship between risk-pooling and growth in the determination of welfare. The growth rate responds to changes in the wealth distribution and displays transitional dynamics towards the balanced growth path. (C) 2015 Elsevier Inc.

Beside activating inactive women, one possible solution is to support the re-integration of unemployed women. Due to female-specific labor market constraints (preferences for flexible working hours, discrimination), this is a difficult task, and the question arises whether active labor market policies (ALMP) are an appropriate tool to help. It has been shown that the effectiveness of traditional (ALMP) programs-which focus on the integration in dependent (potentially inflexible) employment-is positive but limited. At the same time, recent evidence for Austria shows that these programs reduce fertility which might be judged unfavorable from a societal perspective. Promoting self-employment among unemployed women might therefore be a promising alternative. Starting their own business might give women more independence and flexibility to reconcile work and family and increase labor market participation. Based on long-term informative data, we find that start-up programs persistently integrate former unemployed women into the labor market, and the impact on fertility is less detrimental than for traditional ALMP programs.}, language = {en} } @article{CaliendoHogenackerKuennetal.2015, author = {Caliendo, Marco and Hogenacker, Jens and Kuenn, Steffen and Wiessner, Frank}, title = {Subsidized start-ups out of unemployment: a comparison to regular business start-ups}, series = {Small business economics : an international journal}, volume = {45}, journal = {Small business economics : an international journal}, number = {1}, publisher = {Springer}, address = {Dordrecht}, issn = {0921-898X}, doi = {10.1007/s11187-015-9646-0}, pages = {165 -- 190}, year = {2015}, abstract = {Offering unemployed individuals a subsidy to become self-employed is a widespread active labor market policy strategy.

Using a new dataset based on a survey allows us to compare subsidized start-ups out of unemployment with regular business founders, with respect to not only personal characteristics but also business outcomes. The results indicate that previously unemployed entrepreneurs face disadvantages in variables correlated with entrepreneurial ability and access to capital. Nineteen months after start-up, the subsidized businesses experience higher survival, but lag behind regular business founders in terms of income, business growth and innovation.

We then estimate the spatial interdependence of public debt among German municipalities using a panel on municipalities in the two largest German states from 1999 to 2006.
