The chapter examines the dynamics of policy responses and their ultimate effectiveness. It identifies typical sequences of policy failures, caused by the misfit between new problems and existing policy legacies, which may generate processes of policy learning that ultimately produce effective solutions; but it also points to instances in which policy learning is blocked by conflicts of interest or by divergent cognitive orientations in multi‐actor institutional settings. Of equal importance are sequences of lateral spillovers, where the solutions to problems in one policy area generate new problems that subsequently must be dealt with in adjacent policy areas. In the 1970s and 1980s, these spillovers were most important in countries where the rise of open unemployment was mitigated by resort to early retirement and disability pensions. In analysing these sequences of policy failure, learning, and problem displacement, the chapter also compares and assesses the greater or lesser effectiveness of the policy responses actually adopted and identifies successful countries that were able to adjust to the challenges of the open economy without abandoning their welfare‐state goals.Less

This chapter discusses a variational formulation of boundary value problems in small deformation solid mechanics. It begins by introducing the important principle of virtual power, and shows that it encapsulates Cauchy’s traction law, and the local form of the basic balance of forces (equation of equilibrium), and the local from of the balance of moments (symmetry of the stress). Since the principle of virtual power encapsulates both the equation of equilibrium and the Cauchy relation for tractions, it can be used to formulate and solve boundary-value problems in solid mechanics in a variational or weak sense. Specifically, it is shown how the displacement problem of linear elastostatics may be formulated variationally using the principle of virtual power.Less
