The Marginal Propensity to Spend on Adult Children

We examine how much of an extra dollar of parental lifetime resources will ultimately be passed on to adult children in the form of inter vivos transfers and bequests. We infer bequests from the stock of wealth late in life. We use mortality rates and age specific estimates of the response of transfers and wealth to permanent income to compute the expected present discounted values of these responses to permanent income. Our estimates imply that parents pass on between 2 and 3 cents out of an extra dollar of expected lifetime resources in bequests and about 2 cents in transfers. The estimates increase with parental income and are smaller for nonwhites. They imply that about 15 percent of the effect of parental income on lifetime resources of adult children is through transfers and bequests and about 85 percent is through the intergenerational correlation in earnings, although these estimates are sensitive to assumptions about the intergenerational earnings correlation, taxes, and the number of children. We compare our estimates to the implications of alternative computable benchmark models of savings behavior in order to assess the likely importance of intended bequests for the wealth/income relationship.

Fast on-wafer electrical, mechanical, and electromechanical characterization of piezoresistive cantilever force sensors

Validation of a technological process requires an intensive characterization of the performance of the resulting devices, circuits, or systems. The technology for the fabrication of micro and nanoelectromechanical systems (MEMS and NEMS) is evolving rapidly, with new kind of device concepts for applications like sensing or harvesting are being proposed and demonstrated. However, the characterization tools and methods for these new devices are still not fully developed. Here, we present an on-wafer, highly precise, and rapid characterization method to measure the mechanical, electrical, and electromechanical properties of piezoresistive cantilevers. The setup is based on a combination of probe-card and atomic force microscopy technology, it allows accessing many devices across a wafer and it can be applied to a broad range of MEMS and NEMS. Using this setup we have characterized the performance of multiple submicron thick piezoresistive cantilever force sensors. For the best design we have obtained a force sensitivity ℜ_F = 158μV/nN, a noise of 5.8 μV (1 Hz–1 kHz) and a minimum detectable force of 37 pN with a relative standard deviation of σ_r ≈ 8%. This small value of σr, together with a high fabrication yield >95%, validates our fabrication technology. These devices are intended to be used as bio-molecular detectors for the measurement of intermolecular forces between ligand and receptor molecule pairs

The Impact of Fiscal Restraint on Budgetary Allocations for Women's Programs

How did the fiscal restraints exercised during the time of fiscal difficulties in 1997-2003 affect the gender/women-targeted programs of the Philippine government? What does a close scrutiny of the government budget reveal regarding the implicit gender implications of such restraints? Manasan and Villanueva disclose some of their findings.budget analysis, gender analysis, women's programs

Looking Closely on Who Benefits from Public Subsidies in Health Care: a Gender Perspective

Do men benefit more than women from government expenditures in health care? Or do women have the upper hand? Using a sex-differentiated incidence analysis of the various Department of Health program expenditures, this Notes' authors assess who indeed benefits from such expenditures in terms of gender. And why.gender, benefit incidence analysis, gender analysis, public spending in health, sex-differentiated incidence analysis

Why Civil Society Cannot Battle it All Alone: The Roles of Civil Society Environment, Transparent Laws and Quality of Public Administration in Political Corruption Mitigation

Utilizing a large-N data that covers about 20000 observations from about 200 countries from 1789 to 2018 from the Varieties of Democracy (V-Dem) project, and anchored on institutionalism as an overarching theory, and the nascent literature on civil-society corruption nexus, the paper looks at the predictive capacity of civil society environment, transparency of laws and predictability of enforcement, and rigorousness and impartiality of public administration in political corruption. Using a four-step hierarchical multiple regression, results show that while civil society and its structure is a significant determinant of the level of political corruption, the introduction of transparency of laws and predictability of enforcement, rigorousness, and impartiality of public administration, and civil society environment in the regression model accounted for additional variance in political corruption. Practical and theoretical implications, particularly on civil society-corruption nexus and the broader corruption-democracy linkage, are discussed

Stress-Induced Variations in the Stiffness of Micro- and Nanocantilever Beams

The effect of surface stress on the stiffness of cantilever beams remains an outstanding problem in the physical sciences. While numerous experimental studies report significant stiffness change due to surface stress, theoretical predictions are unable to rigorously and quantitatively reconcile these observations. In this Letter, we present the first controlled measurements of stress-induced change in cantilever stiffness with commensurate theoretical quantification. Simultaneous measurements are also performed on equivalent clamped-clamped beams. All experimental results are quantitatively and accurately predicted using elasticity theory. We also present conclusive experimental evidence for invalidity of the longstanding and unphysical axial force model, which has been widely applied to interpret measurements using cantilever beams. Our findings will be of value in the development of micro- and nanoscale resonant mechanical sensors

Special cantilever geometry for the access of higher oscillation modes in atomic force microscopy

Employing higher oscillation modes of microcantilevers promises higher sensitivity when applied as sensors, for example, for mass detection or in atomic force microscopy. Introducing a special cantilever geometry, we show that the relation between the resonance frequencies of the first and second resonance modes can be modified to separate them further or to bring them closer together. In atomic force microscopy the latter is of special interest as the photodiode of the beam deflection detection limits the accessible frequency range. Using finite element simulations, we optimized the design of the modified cantilever geometry for a maximum reduction of the frequency of the second oscillation mode with respect to the first mode. Cantilevers were fabricated by silicon micromachining and subsequently utilized in an ultrahigh vacuum Kelvin probe force microscope imaging the surface potential of C60 on graphit
