Marketers are currently focused on proper budget allocation to maximize ROI from online advertising. They use conversion attribution models assessing the impact of specific media channels (display, search engine ads, social media, etc.). Marketers use the data gathered from paid, owned, and...

The Philippine government has historically underinvested in transport infrastructure until a few decades ago when the country was in a relatively more favorable financial position. The immense need to fast-track transport infrastructure investments is driven mainly by two pressure points: 1) the...

We investigate the effects of the Indonesian decentralization and democratization process on budget allocation at the sub-national level. Based on panel data for 271 Indonesian districts for the years of 1994 to 2009, we address the determinants of local investment expenditures in public...

We analyse whether there is a relationship between EU Commissioners’ national origin and political outcomes. For this purpose, we argue that examining the Commissioner for Agriculture allows the most precise empirical identification: there is a specific budget for agriculture which accounts...

We analyze optimal control problems for two-phase Navier-Stokes equations with surface tension. Based on Lp-maximal regularity of the underlying linear problem and recent well-posedness results of the problem for sufficiently small data we show the differentiability of the solution with respect...

We are concerned with the simulation and optimization of large-scale gas pipeline systems in an error-controlled environment. The gas flow dynamics is locally approximated by sufficiently accurate physical models taken from a hierarchy of decreasing complexity and varying over time. Feasible...

Hammerstein–Wiener models constitute a significant class of block-structured dynamic models, as they approximate process nonlinearities on the basis of input–output data without requiring identification of a full nonlinear process model. Optimization problems with Hammerstein–Wiener models...

This paper presents a unified theory of human capital with both health capital and, what we term, skill capital endogenously determined within the model. By considering joint investment in health capital and in skill capital, the model highlights similarities and differences in these two...

We study semigroups of convex monotone operators on spaces of continuous functions and their behaviour with respect to Γ-convergence. In contrast to the linear theory, the domain of the generator is, in general, not invariant under the semigroup. To overcome this issue, we consider different...
