  • Amenities, affordability, and housing vouchers 

    Bieri, D.S.; Dawkins, C.J. (Blackwell Publishing Inc., 2018-06-19)
    Against the background of an emerging rental affordability crisis, we examine how the standard rule that households should not spend more than 30% of their income on housing expenditures leads to inefficiencies in the ...
  • Frustration and Anger in Games 

    Battigalli, Pierpaolo; Dufwenberg, Martin; Smith, Alec (Virginia Tech, 2015-08-24)
    Frustration, anger, and aggression have important consequences for economic and social behavior, concerning for example monopoly pricing, contracting, bargaining, traffic safety, violence, and politics. Drawing on insights ...
  • Subset-Continuous-Updating GMM Estimators for Dynamic Panel Data Models 

    Ashley, Richard A.; Sun, Xiaojin (MDPI, 2016-11-30)
    The two-step GMM estimators of Arellano and Bond (1991) and Blundell and Bond (1998) for dynamic panel data models have been widely used in empirical work; however, neither of them performs well in small samples with weak ...
  • Cloud-Sourcing: Using an Online Labor Force to Detect Clouds and Cloud Shadows in Landsat Images 

    Yu, Ling; Ball, Sheryl B.; Blinn, Christine E.; Moeltner, Klaus; Peery, Seth; Thomas, Valerie A.; Wynne, Randolph H. (MDPI, 2015-02-26)
    We recruit an online labor force through’s Mechanical Turk platform to identify clouds and cloud shadows in Landsat satellite images. We find that a large group of workers can be mobilized quickly and relatively ...
  • Credible Granger-Causality Inference with Modest Sample Lengths: A Cross-Sample Validation Approach 

    Ashley, Richard A.; Tsang, Kwok Ping (MDPI, 2014-03-25)
    Credible Granger-causality analysis appears to require post-sample inference, as it is well-known that in-sample fit can be a poor guide to actual forecasting effectiveness. However, post-sample model testing requires an ...
  • Revisiting Simpson's Paradox: a statistical misspecification perspective 

    Spanos, A
    The primary objective of this paper is to revisit Simpson's paradox using a statistical misspecification perspective. It is argued that the reversal of statistical associations is sometimes spurious, stemming from invalid ...
  • Revisiting the Neyman-Scott model: an Inconsistent MLE or an Ill-defined Model? 

    Spanos, A
    The Neyman and Scott (1948) model is widely used to demonstrate a serious weakness of the Maximum Likelihood (ML) method: it can give rise to inconsistent estimators. The primary objective of this paper is to revisit this ...
  • Where do statistical models come from? Revisiting the problem of specification 

    Spanos, A
    R. A. Fisher founded modern statistical inference in 1922 and identified its fundamental problems to be: specification, estimation and distribution. Since then the problem of statistical model specification has received ...
  • The Two Envelope Problem: a Paradox or Fallacious Reasoning? 

    Spanos, A
    The primary objective of this note is to revisit the two envelope problem and propose a simple resolution. It is argued that the paradox arises from the ambiguity associated with the money content $x of the chosen envelope. ...
  • Why the Decision Theoretic Perspective Misrepresents Frequentist Inference: 'Nuts and Bolts' vs. Learning from Data 

    Spanos, A
    The primary objective of this paper is to revisit and make a case for the merits of R.A. Fisher's objections to the decision-theoretic framing of frequentist inference. It is argued that this framing is congruent with the ...
  • Asset Prices with Random Investor Types 

    Tsang, KP; Tserenjigmid, G
  • Bearing estimation using a perturbed linear array 

    Hinich, Melvin J. (Acoustical Society of America, 1977-06)
    A linear hydrophone array which is towed in the ocean is subject to snakelike bending. If the array is processed as if it was truly linear, the author has shown that the bending causes a deflection of the measured bearing ...
  • Estimating bearing when the source is endfire to an array 

    Hinich, Melvin J. (Acoustical Society of America, 1979-03)
    Consider the problem of estimating the direction of arrival of a plane wave using a linear array of length L with M sensors. Let 0 denote the direction with respect to the array axis. Assume that we know that 0 >0. The ...
  • On errors in some papers on array processing 

    Hinich, Melvin J. (Acoustical Society of America, 1979-02)
    Some errors in the literature are noted concerning the calculation of the maximum-likelihood estimator.
  • Statistical approach to passive target tracking 

    Hinich, Melvin J.; Bloom, Michael C. (Acoustical Society of America, 1981-03)
    The paper presents a method for passively tracking a moving target using a sequence of bearings from a surveillance platform. The key assumption for the method is that the target is moving at a constant speed on a fixed ...
  • Maximum likelihood estimation of the position of a radiating source in a waveguide 

    Hinich, Melvin J. (Acoustical Society of America, 1979-09)
    An array of sensors is receiving radiation from a source of interest. The source and the array are in a one-or two-dimensional waveguide. The maximum-likelihood estimators of the coordinates of the source are analysed under ...
  • Beamforming when the sound velocity is not precisely known 

    Hinich, Melvin J. (Acoustical Society of America, 1980-08)
    Beamforming is an integral part of most signal processingsystems in active or passive sonars. The delays used to generate a beam are functions of the sound velocity, which depends on temperature, salinity, and pressure. ...
  • Passive range estimation using subarray parallax 

    Hinich, Melvin J. (Acoustical Society of America, 1979-05)
    Consider a large aperture linear array which is detecting coherent radiation from a source. Suppose that the array is processed as a string of subarrays consisting of adjacent sensors. Assume that the signal is a plane ...
  • Bearing estimation using a large towed array 

    Hinich, Melvin J.; Rule, William (Acoustical Society of America, 1975)
    When a towed array of hydrophones is significantly nonlinear due to bending, ordinary linear array beamforming gives a biased estimate of the true source bearing. By processing the array as a sequence of smaller aperture ...
  • Estimating signal and noise using a random array 

    Hinich, Melvin J. (Acoustical Society of America, 1982-01)
    This paper presents approximations for the rms error of the maximum likelihood estimator of the direction of a plane wave incident on a random array. The sensor locations are assumed to be realizations of independent, ...
