Estimating The Income Loss Of Disabled Individuals: The Case Of Spain, Maria Cervini-Plá, José I. Silva, Judit Vall Sep 2016

Estimating The Income Loss Of Disabled Individuals: The Case Of Spain, Maria Cervini-Plá, José I. Silva, Judit Vall

José Ignacio Silva

In this paper we present a theoretical model along with an empirical model to identify the effects of disability on wages. From the theoretical model we derive the hypothesis that only the temporary component of the wage gap, which is due to assimilation costs, will diminish over time, whereas the permanent element, which is due to the productivity loss after the disabling condition, will in fact persist. We test this theoretical hypothesis using an exogenous disability shock (accident) and combine propensity score matching with a difference-in-differences method to account for observed and unobserved time-constant differences. In all our specifications we …

Contract Structure For Joint Production: Risk And Ambiguity Under Compensatory Damages, Michael D. Ryall, Rachelle C. Sampson Jul 2016

Contract Structure For Joint Production: Risk And Ambiguity Under Compensatory Damages, Michael D. Ryall, Rachelle C. Sampson

Michael D Ryall

We develop a model in which the parties to a joint production project have a choice of specifying contractual performance in terms of actions or deliverables. Penalties for noncompliance are not specified; rather, they are left to the courts under the legal doctrine of compensatory damages. We analyze three scenarios of increasing uncertainty: Full Knowledge - where implications of partner actions are known; Risk - where implications can be probabilistically quantified; and, Ambiguity - where implications cannot be so quantified. Under Full Knowledge, action requirements dominate: they always induce the maximum economic value. This dominance vanishes in the Risk scenario. …

Optimal Task Assignments, Felipe Balmaceda Assoc Prof. Jul 2016

Optimal Task Assignments, Felipe Balmaceda Assoc Prof.

Felipe Balmaceda

This paper studies optimal task assignments in a risk neutral principal-agent model in which agents are compensated according to an aggregated performance measure. The main trade-off involved is one in which specialization allows the implementation of any possible effort profile, while multitasking constraint the set of implementable effort profiles. Yet, the implementation of any effort profile in this set is less expensive than that under specialization. The principal prefers multitasking to specialization except when tasks are complements and the output after success is small enough so that it is not second-best optimal to implement high effort in each task. This …

Lodging The Sustainable Development Goals In The International Trade Regime: From Trade Rhetoric To Trade Plethoric, Nasser A. Alreshaid Jun 2016

Lodging The Sustainable Development Goals In The International Trade Regime: From Trade Rhetoric To Trade Plethoric, Nasser A. Alreshaid

Nasser A Alreshaid

While the international community is stimulated by the new sustainable development goals’ impetus, the global trade regime lives through its 40’s mid-life crisis and anticipates what it does not know. Views of the multilateral trading system being stalled by a proliferation of other preferential trade agreements, signal a deep inquiry into this policy trend. What this paper intends to highlight though, is that if lessons are drawn from the new sustainable development goals, these global trade challenges could be mere air turbulence. By introducing the needs of states and their constituents through these goals, an inclusive and more representative international …

A Theory Of Political Entrenchment, Gilles Saint-Paul, Davide Ticchi, Andrea Vindigni Jun 2016

A Theory Of Political Entrenchment, Gilles Saint-Paul, Davide Ticchi, Andrea Vindigni

Davide Ticchi

We develop a theory of endogenous political entrenchment in a simple two-party dynamic model of income redistribution with probabilistic voting. A partially self-interested left-wing party may implement (entrenchment) policies reducing the income of its own constituency, the lower class, in order to consolidate its future political power. Such policies increase the net gain that low-skill agents obtain from income redistribution, which only the Left (but not the Right) can credibly commit to provide, and therefore may help offsetting a potential future aggregate ideological shock averse to the left-wing party. We demonstrate that political entrenchment by the Left occurs only if …

Testing Homogeneity In Semiparametric Mixture Case-Control Models, C Z. Di, G Kc Chan, C Zheng, Ky Liang Jun 2016

Testing Homogeneity In Semiparametric Mixture Case-Control Models, C Z. Di, G Kc Chan, C Zheng, Ky Liang

Chongzhi Di

Recently, Qin and Liang (Biometrics, 2011) considered a semiparametric mixture case-control model and proposed a score test for homogeneity. The mixture model is semiparametric in the sense that the density ratio of two distributions is assumed to be of exponential form, while the baseline density is unspecified. In a family of parametric admixture models, Di and Liang (Biometrics, 2011) showed that the likelihood ratio test statistics, which is equivalent to a supremum statistics, could improve power over score tests. We generalize the likelihood ratio or supremum statistics to the semiparametric mixture model and demonstrate the power gain over the score …

Single-Firm Event Studies, Securities Fraud, And Financial Crisis: Problems Of Inference, Andrew Baker May 2016

Single-Firm Event Studies, Securities Fraud, And Financial Crisis: Problems Of Inference, Andrew Baker

Andrew Baker

Lawsuits brought pursuant to section 10(b) of the Securities and Exchange Actdepend on the reliability of a statistical tool called an event study to adjudicate issues ofreliance, materiality, loss causation, and damages. Although judicial acceptance of theevent study technique is pervasive, there has been little empirical analysis of the ability ofevent studies to produce reliable results when applied to a single company’s security.
Using data from the recent financial crisis, this Note demonstrates that the standardmodelevent study used in most court proceedings can lead to biased inferences sanctionedthrough the Daubert standard of admissibility for expert testimony. In particular, in thepresence …

3d Printing And Healthcare: Will Laws, Lawyers, And Companies Stand In The Way Of Patient Care?, Evan R. Youngstrom Apr 2016

3d Printing And Healthcare: Will Laws, Lawyers, And Companies Stand In The Way Of Patient Care?, Evan R. Youngstrom

Evan R. Youngstrom

Today, our society is on a precipice of significant advancement in healthcare because 3D printing will usher in the next generation of medicine. The next generation will be driven by customization, which will allow doctors to replace limbs and individualize drugs. However, the next generation will be without large pharmaceutical companies and their justifications for strong intellectual property rights. However, the current patent system (which is underpinned by a social tradeoff made from property incentives) is not flexible enough to cope with 3D printing’s rapid development. Very soon, the social tradeoff will no longer benefit society, so it must be …

The Bidder's Curse: Comment, Henry S. Schneider Apr 2016

The Bidder's Curse: Comment, Henry S. Schneider

Henry S Schneider

The prices of auctions on eBay often exceed eBay’s fixed-price “Buy-It-Now” prices. I investigate the causes of this overbidding, focusing on the interpretation in Malmendier and Lee (2011) that the observed overbidding cannot be explained “without allowing for nonstandard preferences or beliefs” and that the “strongest direct evidence points to limited attention.” Using data from their study and new data from eBay, I provide evidence that a key condition for identifying nonstandard behavior may not have been met, and that the observed overbidding is not inconsistent with standard behavior once we allow for the likely presence of search costs.

James Wilson And The Moral Foundations Of Popular Sovereignty, Ian C. Bartrum Apr 2016

James Wilson And The Moral Foundations Of Popular Sovereignty, Ian C. Bartrum

Ian C Bartrum

This paper explores the moral philosophy underlying the constitutional doctrine of popular sovereignty. In particular, it focuses on the Scottish sentimentalism that informed James Wilson’s understanding of that doctrine. Wilson, a transplanted Scotsman, was perhaps the nation’s preeminent lawyer in the middle 1780s. He was one of the most important delegates to the Constitutional Convention, one of the nation’s first law professors, and served as Associate Justice on the first Supreme Court. In these capacities, he developed the most sophisticated and coherent account of popular sovereignty among the founding generation. My initial effort is to enrich our understanding of Wilson’s …

A Unified Model Of Adaptive Learning In Normal Form Games, Naoki Funai Feb 2016

A Unified Model Of Adaptive Learning In Normal Form Games, Naoki Funai

Naoki Funai

We investigate an adaptive learning model which nests several existing learning models such as payoff assessment learning, valuation learning, stochastic fictitious play learning, experience-weighted attraction learning and delta learning with indirect payoff information in normal form games. In this paper, we consider adaptive players each of whom (i) assigns payoff assessments to his own actions, (ii) chooses an action which has the highest assessment with some perturbations, and (iii) updates the assessments using observed payoffs, which may include payoffs from unchosen actions, in each period. Utilising the asynchronous stochastic approximation method introduced by Tsitsiklis (1994), we provide conditions under which …

Comparing The Effects Of Direct And Indirect Learning Strategies On Iranian Efl Learners' Vocabulary Learning, Ali Taghinezhad Feb 2016

Comparing The Effects Of Direct And Indirect Learning Strategies On Iranian Efl Learners' Vocabulary Learning, Ali Taghinezhad

Ali Taghinezhad

Vocabulary is vital to English language teaching since without a sufficient knowledge ofvocabulary students are not able to understand others or to express their ideas. Therefore,several indirect and direct strategies have been proposed to improve vocabulary learning.Whether indirect or direct strategies can contribute more to vocabulary learning has been asignificant issue. Therefore, this study aimed at investigating the influence of indirect anddirect learning strategies on the vocabulary learning of Iranian EFL learners. To this end,ninety upper-intermediate students were selected from two English language institutes inShiraz, Iran. Students were divided into two experimental groups. One experimental group(A) received vocabulary instruction using …

Technical Problem Based E-Language Instruction For Vocational Students, Eleni Papantoniou, Thanasis Hadzilacos Jan 2016

Technical Problem Based E-Language Instruction For Vocational Students, Eleni Papantoniou, Thanasis Hadzilacos

Eleni Papantoniou

We discuss an intervention in mother language instruction in a Greek Vocational Lyceum combining Web 2.0 tools with electronic writing pedagogy. During a full school year (2012-13), forty six 11th grade students with typically low literacy skills participated, randomly separated in control and experimental group. The latter systematically dealt with Technical Problem Solving and completed online (Edmodo) increasingly complex writing tasks. Encouraged to reflect on and solve technical problems, they activated language skills for communicating their solutions through the synthesis of technical text-genres. Meanwhile the control group followed the conventional teaching method using the usual literary texts. Pre and post-test …

Allotment In First-Price Auctions: An Experimental Investigation, Luca Corazzini, Stefano Galavotti, Paola Valbonesi, Rupert Sausgruber Jan 2016

Allotment In First-Price Auctions: An Experimental Investigation, Luca Corazzini, Stefano Galavotti, Paola Valbonesi, Rupert Sausgruber

Paola Valbonesi

We experimentally study the effects of allotment - the division of an item into homogeneousunits - in independent private value auctions. We compare a bundling first-priceauction with two equivalent treatments where allotment is implemented: a two-unit discriminatoryauction and two simultaneous single-unit first-price auctions. We find thatallotment in the form of a discriminatory auction generates a loss of efficiency with respectto bundling. In the allotment treatments, we observe large and persistent bid spread, andthe discriminatory auction is less efficient than simultaneous auctions. We provide a unified interpretation of our results that is based on both a non-equilibrium response to thecoordination problem …

Fabrication Of Micro-Meltblown Filtration Media Using Parallel Plate Die Design, Mohammad A. Hassan Jan 2016

Fabrication Of Micro-Meltblown Filtration Media Using Parallel Plate Die Design, Mohammad A. Hassan

Mohammad Abouelreesh Hassan

Meltblown fibers are typically produced using a die technology based on the slot concept, an extension of the sheet die technology with a series of holes substituting the center rectangular slot of the sheet die. While this prevalent technology has met with considerable success, an economical, facile design would be desirable. In this study a new parallel plate die concept to fabricate micro-meltblown fibers that offers simplicity, ease of use, and low cost was examined. The new die concept had parallel plates forming channels for polymer melt to flow through with a set of air holes surrounding them. This die …

Quantile Regression With Nonadditive Fixed Effects, David Powell Jan 2016

Quantile Regression With Nonadditive Fixed Effects, David Powell

David Powell

This paper introduces a quantile regression estimator for panel data (QRPD) with nonadditive fixed effects, maintaining the nonseparable disturbance term commonly associated with quantile estimation. QRPD estimates the impact of exogenous or endogenous treatment variables on the outcome distribution using ``within" variation in the treatment variables or instruments for identification purposes. Most quantile panel data estimators include additive fixed effects which separates the disturbance term and assumes the parameters vary based only on the time-varying components of the disturbance term. QRPD is consistent for small T and straightforward to implement. The nonadditive fixed effects are never estimated or even specified. …

Optimal Health Insurance And The Distortionary Effects Of The Tax Subsidy, David Powell Jan 2016

Optimal Health Insurance And The Distortionary Effects Of The Tax Subsidy, David Powell

David Powell

The tax exclusion of health insurance premiums represents the largest source of tax expenditures in the United States while reducing the after-tax price of insurance for the majority of households. This paper develops a model of optimal health insurance in the presence of a tax-deductible premium as well as considering the implications of the Affordable Care Act's ``Cadillac tax." While there is a long literature discussing the possible consequences of subsidizing health insurance through the tax code, we have little evidence about how the tax subsidy distorts the optimal cost-sharing schedule for a household. This paper provides theoretical and empirical …

Complexity Theory For A New Managerial Paradigm: A Research Framework, Gandolfo Dominici, Vasja Roblek

Vasja Roblek

In this work, we have outlined a research framework for a new management paradigm, attempting trying to link the main concepts of complexity theory, change management, knowledge management, sustainable development and, cybernetics. We discussed the transition from the industrial era to the post industrial age. In the development process, nothing is fixed in advance; we can say that it is opportunistic, and adapts to the challenges of the environment, as well as to their effects for and within organizations and society. We saw how the processes of organizational change have occurred as a result of the move to adapt to …

Crashing Into The Unknown: An Examination Of Crash Optimization Algorithms Through The Two Lanes Of Ethics And Law, Jeffrey K. Gurney Jan 2016

Crashing Into The Unknown: An Examination Of Crash Optimization Algorithms Through The Two Lanes Of Ethics And Law, Jeffrey K. Gurney

Jeffrey K Gurney

Autonomous vehicles will encounter situations where an accident is truly unavoidable, requiring the vehicle to decide whom or what to hit. In such situations, the vehicle will make difficult ethical decisions based upon its programming — more specifically, how its crash-optimization algorithm is programmed.This Article examines crash-optimization algorithms from an ethical and legal standpoint through the lenses of six moral dilemmas. Ethically, the Article focuses specifically on utilitarian and Kantian ethics. Legally, the Article considers the tort and criminal law implications of crash-optimization algorithms.In addition, the Article discusses whether autonomous vehicles should even make ethical decisions. Concluding that they should …

The Myth Of The Trade Secret Troll: Why We Need A Federal Civil Claim For Trade Secret Misappropriation, James Pooley Jan 2016

The Myth Of The Trade Secret Troll: Why We Need A Federal Civil Claim For Trade Secret Misappropriation, James Pooley

James Pooley

Trade secret theft is a federal crime, but civil cases must be brought in state court. Because commerce is now global and most assets are information-based, misappropriation is easier, faster and quicker. State court processes are insufficient for interstate or international disputes. The proposed Defend Trade Secrets Act of 2015 would address the problem by adding a civil claim to the Economic Espionage Act. Arguments against it tend to be based on incorrect assumptions or speculation. The legislation provides sufficient safeguards against abuse, and would not inhibit labor mobility or lead to the appearance of "trade secret trolls."
