This article builds on the intellectual legacy of Jan Tinbergen by extending his analysis welfare and security into a framework involving strategic interaction. I first incorporate in terms interstate tensions single utility or payoff function. An uncertain world is characterized states that are more peaceful, others where nations hostile to each other. Both conflictual peaceful outcomes lie al...

The expansion of welfare-state arrangements is seen as the result of dynamic interaction between market behaviour and political behaviour, often with considerable time lags, sometimes generating either virtuous or vicious circles.

Could computing service providers have to ensure that the service applications, cloud software, and the physical location of the cloud are secure. Furthermore, providers need to ensure that the service is secure on the client’s side of the system. To examine the client side security level we build economic models that consider the tradeoffs between system usability and client side security rest...

This paper shows the macroeconomic and welfare implications of an aging population in the United States, using a heterogeneous-agent overlapping-generations model with uninsurable idiosyncratic working ability shocks and mortality shocks. The model uses three population projections in Social Security Administration (2003), and generates economies as equilibrium transition paths from 1961 to 220...

This paper studies the long-run aggregate and welfare effects of eliminating Social Security in a quantitative dynamic general equilibrium life-cycle model where parents and their children are linked by voluntary and accidental bequests. Social security in this model with impure altruism has a smaller effect on capital accumulation than in a pure life-cycle model, a bigger effect than in a mode...
