This paper examines the impact of a change in the German child benefit system in 1996, which led to a large increase in lump sum transfers to families with children. We analyze the impact on the labor force participation of family members as well as on household consumption directed to children. Comparing behavioral changes of adults with children with behavioral changes of adults without child...

This paper examines Ricardian equivalence in a world in which taxes are not lump sum, but are levied on risky labor income. It shows that the marginal propensity to consume out of a tax cut, coupled with a future income tax increase, can be substantial under plausible assumptions. Indeed, the MPC out of a tax cut can be closer to the Keynesian value that ignores the future tax liabilities than ...

I undertake a quantitative investigation into the short run effects of changes in the timing of taxes for model economies in which heterogeneous households face a borrowing constraint. A combination of the distortionary effects of non-lump-sum taxation and the liquidity effects arising from the asset market structure are found to imply large real effects from tax changes. For example, a tempora...

An equivalent circuit, made of the chain connection of a number of T-type two-port networks, is proposed for the very accurate representation of the frequency-domain behavior of radially inhomogeneous solitary cylindrical structures, the individual two-port networks being made of frequency-independent R, L and C lumped elements. The accuracy of the model is dictated by the number of two-port ne...

This paper presents a new approach to identify distributed parameters of a lumped-element model for a power transformer. A simplified circuit of a lumped-element model is developed to calculate frequency responses of transformer windings in a wide range of frequency domain. In order to seek optimal parameters of the simplified circuit of the transformer, an intelligent learning technique, based...

In this paper we present two models for joint stock replenishment and shipment consolidation decisions which arise in the context of vendor managed inventory. Stock replenishment from suppliers or shipment to customers each incurs a lump-sum cost to the vendor. We assume the vendor uses the reorder point, lot-size policy to replenish stock and one of two schemes to dispatch shipment: the time-b...

Three-dimensional solitary waves or lump solitons are known to be solutions to the Kadomtsev–Petviashvili I equation, which models small-amplitude shallow-water waves when the Bond number is greater than 1 3 . Recently, Pego and Quintero presented a proof of the existence of such waves for the Benney–Luke equation with surface tension. Here we establish an explicit connection between the lump s...

Low-energy dynamics in the unit-charge sector of the CP 1 model on spherical space (space-time S 2 × R) is treated in the approximation of geodesic motion on the moduli space of static solutions, a six-dimensional manifold with non-trivial topology and metric. The structure of the induced metric is restricted by consideration of the isometry group inherited from global symmetries of the full fi...

We develop a model of education where individuals face educational risk. Successful graduation depends on individual effort to study and public resources. After realization of risk, they either work as skilled or as unskilled worker. We show that an optimal public policy consists of tuition fees combined with skill-contingent loans, lump-sum transfers/taxes, and public funding of the educationa...
