Abstract In recent decades, citizenship policies in Europe have changed significantly: some governments have introduced restrictive new requirements for citizenship, while others have made citizenship more accessible. What explains this variation? Despite a burgeoning literature on both comparative citizenship and spatial competition among parties, scholarship on this question remains in its infancy and primarily focused on the influence of the far right. Expanding on this growing research, this article argues that citizenship policy change results from electoral competition on both sides of the political spectrum, in conjunction with governments’ ideological orientation. Using new data on citizenship policies across sixteen European countries from 1975 to 2014, the author demonstrates that left-of-center governments facing increasing levels of left party competition are associated with more accessible policy changes, while increasing levels of party competition from the far right yield more restrictive policy changes under not only right-of-center governments, but also centrist and left-of-center governments as well.

Abstract Asylum policies are interdependent across countries: policy choices in one country can affect refugee flows into neighbouring countries and may provoke policy changes there, in an a priori unknown direction. We formulate a dynamic model of refugees’ location choices and of the strategic interaction among destinations that we fit to Syrian refugee migration to Europe. We find that south and southeastern European countries view recognition rates as strategic substitutes, whereas the same policies can be strategic complements in northern Europe. Our findings imply that regression frameworks which use cross-country variation to estimate the effects of recognition rates on immigration underestimate (overestimate) the effect if this policy is a strategic substitute (complement).

This paper contributes to the debate on anti-doping policies not by evaluating the policy itself but by evaluating the announcement of (new) policy measures. We develop a dynamic model for analyzing the effects of two different types of news shocks: (1) the preannouncement of improved drug testing technological opportunities and (2) the preannouncement of future increases in financial sanctions. We find that the anticipation of policy changes affects the behavior of potentially delinquent athletes. In both scenarios, our simulations show immediately reduced drug abuse among athletes. We conclude that authorities may consider news shocks as an anti-doping strategy.

Volume is a highly regulated property of cells, because it critically affects intracellular concentration. In the present chapter, we focus on the short-term volume regulation in yeast as a consequence of a shift in extracellular osmotic conditions. We review a basic thermodynamic framework to model volume and solute flows. In addition, we try to select a model for turgor, which is an important hydrodynamic property, especially in walled cells. Finally, we demonstrate the validity of the presented approach by fitting the dynamic model to a time course of volume change upon osmotic shock in yeast.
