Privacy In Location Aware Computing Environments, Denise Anthony, Tristan Henderson, David Kotz
Privacy In Location Aware Computing Environments, Denise Anthony, Tristan Henderson, David Kotz
Dartmouth Scholarship
As location-aware and pervasive computing technologies become more prevalent, privacy concerns are becoming increasingly more important. User preferences about location privacy may depend on place, not only in terms of their physical location but also in terms of their social context: how they define where they are, what they are doing, and whom they are with at the time. Using the experience sampling method, the authors explored the privacy preferences of 25 users during one week. They found that participants were more willing to share location information when at home or alone than when at other locations or with friends. …
Individual Consumption Risk And The Welfare Cost Of Business Cycles, Massimiliano De Santis
Individual Consumption Risk And The Welfare Cost Of Business Cycles, Massimiliano De Santis
Dartmouth Scholarship
This paper measures the welfare gain from removing aggregate consumption fluctuations starting from an economy in which each individual faces both aggregate and idiosyncratic income shocks, and incomplete consumption insurance. We show that, because this welfare gain is a convex function of the overall consumption risk — aggregate plus idiosyncratic — each individual faces, to gauge the magnitude of the gain, it is important to match individuals’ overall risk prior to any policy. We also show that the convexity of the welfare gain function increases substantially if individual consumption risk contains a realistic random walk component. While being agnostic about …
The Shift From Defined Benefit Pensions To 401(K) Plans And The Pension Assets Of The Baby Boom Cohort, James Poterba, Steven Venti, David A. Wise
The Shift From Defined Benefit Pensions To 401(K) Plans And The Pension Assets Of The Baby Boom Cohort, James Poterba, Steven Venti, David A. Wise
Dartmouth Scholarship
The rise of 401(k) plans and the decline of defined benefit plans will have an important effect on the wealth of future retirees. Changing demographic structure also will affect the aggregate stock of retirement wealth. We project the stock of assets held in retirement plans and the average retirement saving of retirees through 2040. Our projections show large increases in wealth at retirement, especially if the returns on corporate equities are comparable with historical returns. Retirement wealth will grow, however, even if equity returns fall substantially below their historical level.
The Identity Of The Generator In The Problem Of Social Cost, Rohan Pitchford, Christopher M. Snyder
The Identity Of The Generator In The Problem Of Social Cost, Rohan Pitchford, Christopher M. Snyder
Dartmouth Scholarship
One of Coase's central insights is that distinguishing between the generator and recipient of an externality is of limited value because externality problems are reciprocal. We reconsider the relevance of the identity of the generator in a model with non-contractible investment ex ante but frictionless bargaining over the externality ex post. In this framework, a party may distort its investment to worsen the other's threat point in bargaining. We demonstrate that the presence of this distortion depends, among other factors, on whether the investing party is a generator. Social efficiency can sometimes be improved by conditioning property rights on the …
Detecting Agency From The Biological Motion Of Veridical Vs Animated Agents, Raymond A. Mar, William M. Kelley, Todd F. Heatherton, C. Neil Macrae
Detecting Agency From The Biological Motion Of Veridical Vs Animated Agents, Raymond A. Mar, William M. Kelley, Todd F. Heatherton, C. Neil Macrae
Dartmouth Scholarship
The ability to detect agency is fundamental for understanding the social world. Underlying this capacity are neural circuits that respond to patterns of intentional biological motion in the superior temporal sulcus and temporoparietal junction. Here we show that the brain's blood oxygenation level dependent (BOLD) response to such motion is modulated by the representation of the actor. Dynamic social interactions were portrayed by either live-action agents or computer-animated agents, enacting the exact same patterns of biological motion. Using an event-related design, we found that the BOLD response associated with the perception and interpretation of agency was greater when identical physical …
Changes In Nitrogen Cycling During The Past Century In A Northern Hardwood Forest, Kendra K. Mclauchlan, Joseph M. Craine, W. Wyatt Oswald, Peter R. Leavitt, Gene E. Likens
Changes In Nitrogen Cycling During The Past Century In A Northern Hardwood Forest, Kendra K. Mclauchlan, Joseph M. Craine, W. Wyatt Oswald, Peter R. Leavitt, Gene E. Likens
Dartmouth Scholarship
Nitrogen (N) availability, defined here as the supply of N to terrestrial plants and soil microorganisms relative to their N demands, limits the productivity of many temperate zone forests and in part determines ecosystem carbon (C) content. Despite multidecadal monitoring of N in streams, the long-term record of N availability in forests of the northeastern United States is largely unknown. Therefore, although these forests have been receiving anthropogenic N deposition for the past few decades, it is still uncertain whether terrestrial N availability has changed during this time and, subsequently, whether forest ecosystems have responded to increased N deposition. Here, …
Academic Journal Prices In A Digital Age: A Two-Sided-Market Model, Mark J. Mccabe, Christopher M. Snyder
Academic Journal Prices In A Digital Age: A Two-Sided-Market Model, Mark J. Mccabe, Christopher M. Snyder
Dartmouth Scholarship
Digital-age technologies promise to revolutionize the market for academic journals as they have other media. We model journals as intermediaries linking authors with readers in a two-sided market. We use the model to study the division of fees between authors and readers under various market structures, ranging from monopoly to free entry. The results help explain why print journals traditionally obtained most of their revenue from subscription fees. The results raise the possibility that digitization may lead to a proliferation of online journals targeting various author types. The paper contributes to the literature on two-sided markets in its analysis of …
Are You Sure You're Saving Enough For Retirement?, Jonathan Skinner
Are You Sure You're Saving Enough For Retirement?, Jonathan Skinner
Dartmouth Scholarship
Many view the soon-to-retire Baby Boomers as woefully unprepared for their golden years, while other economists have taken a more sanguine view of American levels of saving. And if Americans are failures at saving enough for retirement, why are some retirees so happy? The seemingly simple question of "Am I saving enough for retirement?" is apparently not so simple at all. Instead, it touches on a variety of deeper issues in economics, psychology, and health policy. I use the program ESPlanner to present life-cycle retirement wealth targets for a range of incomes and situations typical of American Economic Association members. …
