Lumped element models for the frequency dependence of substrate parasitics in integrated circuits are evaluated. The frequency ranges for which these models are applicable have been identified. Two new models that are suitable for very high frequencies are also presented.

We analyze the investment decision of a ...rm that may complete a project either in one lump or in smaller parts at distinct points in time. The ...rm faces a trade-o¤ between the cost savings that arise when the project is completed in one go and the additional ‡exibility that arises when the ...rm is able to respond to resolving uncertainty by choosing optimal timing individually for each sta...

This paper proposes a general equilibrium model that aims at quantifying the distributive effects of anticipated inflation in an incomplete market economy with heterogeneous agents. Based on empirical evidence, this paper assumes a fixed cost to participate in financial markets, which in equilibrium generates a theory of money. Money is a return dominated asset, but also a costless mean to smoo...

This paper reconsiders the welfare costs of in‡ation and the welfare gains from …nancial intermediation in a heterogeneous-agent economy where money is held as a store of value (as in Bewley, 1980). Because of heterogeneous liquidity demand, transitory lump-sum money injections can have persistent expansionary e¤ects despite ‡exible prices, and such e¤ects can be greatly ampli…ed by the banking...

We re-examine optimal monetary policy when lump-sum taxes are unavailable. Under commitment, we show that, with alternative utility functions to that considered in Nicolini’s related analysis, the direction of the incentive to cheat may depend on the initial level of government debt, with low debt creating an incentive towards surprise deflation, but high debt the reverse. Under discretion, we ...

This paper studies an overlapping generations model with selfish agents, natural resources and human capital externalities. The initial result is to quantify the economic effects of intergenerational transfers by comparing a complete markets allocation with transfers to an allocation without transfers due to incomplete markets. The core contribution is then to show that a higher resource regene...

We consider the 2 + 1 Toda system 1 4 ∆qn = e qn−1−qn − eqn−qn+1 in R, n ∈ Z. It has a traveling wave type solution {Qn} satisfying Qn+1(x, y) = Qn(x + 1 2 √ 2 , y), and is explicitly given by Qn (x, y) = ln 1 4 + ( n− 1 + 2 √ 2x )2 + 4y2 1 4 + ( n+ 2 √ 2x )2 + 4y2 . In this paper we prove that {Qn} is nondegenerate.

This paper studies majority voting over the size and location of a public good when voters di¤er both in income and in their preferences for the public good location. Public good provision is …nanced either by a lump sum tax or by a proportional income tax. We analyze both the simultaneous and the sequential determinations of the public good’s size and location. We show that, while the choice o...

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...
