Ordering Infinite Utility Streams: Efficiency, Continuity, And No Impatience, José Carlos R. Alcantud, Ram Dubey
Ordering Infinite Utility Streams: Efficiency, Continuity, And No Impatience, José Carlos R. Alcantud, Ram Dubey
Department of Economics Faculty Scholarship and Creative Works
We study two related versions of the no-impatience postulate in the context of transitive and reflexive relations on infinite utility streams which are not necessarily complete. Both are excluded by the traditional (weak) anonymity axiom. We show explicit social welfare relations satisfying Strong Pareto and the weaker version of no-impatience that are compatible with continuity in all the traditional topologies in this field. However the stronger version of no-impatience is violated by all lower semi-continuous (in the sup or Campbell topologies) social welfare relations satisfying the Weak Pareto axiom.
Open Source Software: Competition With A Public Good, Vidya Atal, Kameshwari Shankar
Open Source Software: Competition With A Public Good, Vidya Atal, Kameshwari Shankar

This paper looks at price and quality competition in software markets under two different forms of competition—one where two proprietary firms first choose quality and then engage in price competition, and second where a proprietary firm faces competition from an open source software (OSS) firm that allows its users to determine quality level and provides the software at zero price. We find that OSS competition never improves quality for consumers who value quality highly. However, it may provide greater quality to users with a low valuation for quality. In addition, we find that although OSS has a zero market price, …

Arizona’s vulnerable populations are struggling on a daily basis but usually do so in silence, undetected by traditional radar and rankings, often unaware themselves of their high risk for being pushed or pulled into a full crisis. Ineligible for financial assistance under strict eligibility guidelines, they don’t qualify as poor because vulnerable populations are not yet in full crisis. To be clear, this report is not about the “poor,” at least not in the limited sense of the word. It is about our underemployed wage earners, our single-parent households, our deployed or returning military members, our under-educated and unskilled workforce, …
Affirmative Action And Empowerment: Friends Or Foes?, Vidya Atal, Ram Dubey
Affirmative Action And Empowerment: Friends Or Foes?, Vidya Atal, Ram Dubey
Department of Economics Faculty Scholarship and Creative Works
We consider effects of quota or "affirmative action" for women at work-places on the societal outcomes. A simple model of household decision making with production and endogenously determined female power is studied. We show that even under standard economic modeling specifications, as a result of affirmative action, it could turn out to be the case that female labor force participation and social welfare rise but at the cost of diminished female power and wider male-female wage-gap.
Combining Monotonicity And Strong Equity: Construction And Representation Of Orders On Infinite Utility Streams, Ram Dubey, Tapan Mitra
Combining Monotonicity And Strong Equity: Construction And Representation Of Orders On Infinite Utility Streams, Ram Dubey, Tapan Mitra
Department of Economics Faculty Scholarship and Creative Works
This paper studies the nature of social welfare orders (SWO) on infinite utility streams, satisfying the efficiency principle known as monotonicity and the consequentialist equity principle known as strong equity. It provides a complete characterization of domain sets for which there exists such a SWO which is in addition representable by a real valued function. It then shows that for those domain sets for which there is no such SWO which is representable, the existence of such a SWO necessarily entails the existence of a non-Ramsey set, a non-constructive object.
Do All Constructive Strongly Monotone Inter-Temporal Orders Exhibit Impatience?, Kuntal Banerjee, Ram Dubey
Do All Constructive Strongly Monotone Inter-Temporal Orders Exhibit Impatience?, Kuntal Banerjee, Ram Dubey
Department of Economics Faculty Scholarship and Creative Works
In this paper we show that if a strongly monotone inter-temporal order exhibits no preference towards the advancement of timing of future utility on any infinite utility stream, then the existence of such an order must involve some non-constructive device.
Patent Quality And A Two-Tiered Patent System, Vidya Atal, Talia Bar
Patent Quality And A Two-Tiered Patent System, Vidya Atal, Talia Bar
Department of Economics Faculty Scholarship and Creative Works
In this paper, we study the determinants of patent quality and volume of patent applications when inventors care about perceived patent quality. We analyze the effects of various policy reforms, specifically, a proposal to establish a two-tiered patent system. In the two-tiered system, applicants can choose between a regular patent and a more costly, possibly more thoroughly examined, 'gold-plate' patent. Introducing a second patent-tier can reduce patent applications, reduce the incidence of bad patents, and sometimes increase social welfare. The gold-plate tier attracts inventors with high ex-ante probability of validity, but not necessarily applicants with innovations of high economic value.
On Ramsey Equilibrium: Capital Ownership Pattern And Inefficiency, Robert A. Becker, Ram Dubey, Tapan Mitra
On Ramsey Equilibrium: Capital Ownership Pattern And Inefficiency, Robert A. Becker, Ram Dubey, Tapan Mitra
Department of Economics Faculty Scholarship and Creative Works
We provide a sufficient condition on the production function under which eventually the most patient household owns the entire capital stock in every Ramsey equilibrium, called the turnpike property. This generalizes the result in the literature which establishes the turnpike property using the capital income monotonicity condition. We then provide an example of a Ramsey equilibrium in which the most patient household reaches a no capital position infinitely often. This is a strong refutation of the turnpike property on Ramsey equilibria. We also show that the constructed Ramsey equilibrium is inefficient in terms of the aggregate consumption stream that it …
On Construction Of Equitable Social Welfare Orders On Infinite Utility Streams, Ram Dubey, Tapan Mitra
On Construction Of Equitable Social Welfare Orders On Infinite Utility Streams, Ram Dubey, Tapan Mitra
Department of Economics Faculty Scholarship and Creative Works
This paper studies the nature of social welfare orders on infinite utility streams, satisfying the consequentialist equity principles known as Hammond Equity and the Pigou-Dalton transfer principle. The first result shows that every social welfare order satisfying Hammond Equity and the Strong Pareto axioms is non-constructive in nature for all non-trivial domains, Y. The second result shows that, when the domain set is Y = [0, 1], every social welfare order satisfying the Pigou-Dalton transfer principle is non-constructive in nature. Specifically, in both results, we show that the existence of the appropriate social welfare order entails the existence of a …
