The purpose of this paper is to present a framework for the empirical analysis of price and quality choice by a multiproduct monopolist. We do so by demonstrating that well-known techniques from the optimal screening literature used in the theoretical analysis of nonlinear pricing map naturally to the empirical analysis of di erentiated product markets. We then apply a generalized one-dimension...

This paper considers the evaluation of forecasts of a given statistical functional, such as a mean, quantile, or distribution. Recent work has emphasized the importance of evaluating such forecasts using a loss function that is consistent for the functional of interest, of which there are an in…nite number. If forecasters all use correctly speci…ed models, and if the information sets of the com...

In this paper, we analyze application of amorphous Indium– Gallium–Zinc–Oxide thin film transistors (a-InGaZnO TFTs) to voltage-driven pixel electrode circuit that could be used for 4.3in. wide video graphics array (WVGA) full color active-matrix organic light-emitting displays (AM-OLEDs). Simulation results, based on a-InGaZnO TFT and OLED experimental data, show that both device sizes and ope...

Previous research has shown that the reasons for lapsation have important implications regarding the effects of the emerging life settlement market on consumer welfare. We present and empirically implement a dynamic discrete choice model of life insurance decisions to assess the importance of various factors in explaining life insurance lapsations. In order to explain some key features in the d...

The work of Kanter and Sompolinsky [S] on associative memories gives rise to the following question. Let the vectors vl, . . . . v, be chosen randomly from { f 11” (the + 1 vectors of length n). What is the probability that the subspace spanned by v, , . . . . v, over the reals contains a f 1 vector different from fv,, . . . . f v,? (The reals can be replaced by any field of characteristic zero...

Exploiting a rich data set of new vehicle registrations in 22 U.S. Metropolitan Statistical Areas from 1999 to 2006, we analyze the determinants in the demand for hybrid vehicles and examine government programs that aim to promote the adoption of hybrid vehicles. We find that both the recent run-up in gasoline prices from 1999 and federal income tax incentives are important in the diffusion of ...

The aims of this study were to: (1) evaluate the perceptual speech dimensions, speech intelligibility and dys arthria severity of a group of individuals diagnosed with Friedreich’s ataxia (FRDA); (2) determine the presence of subgroups within FRDA dysarthria; (3) investigate the relationship between the speech outcome and the clinical factors of disease progression. The study included 38 indivi...

Objective: To systematically review randomized controlled trials that evaluate the effects of repetitive transcranial magnetic stimulation (rTMS) on rehabilitation aspects related to communication and swallowing functions. Methods: A search was conducted on PubMed, Clinical Trials, Cochrane Library, and ASHA electronic databases. Studies were judged according to the eligibility criteria and ana...

I develop a new method to assess the rational expectations assumption using subjective expectations data. This approach allows the researcher to identify the distributions of the true underlying objective expectations and the expectation bias with respect to unobserved private information. I incorporate subjective longevity expectations into a structural dynamic discrete choice model to explain...

Hepatocellular carcinoma (HCC) is the 6th most common cancer in the world, but the second most common cause of cancer death. There is no universally accepted consensus practice guidelines for HCC owing to rapid developments in new treatment modalities, the heterogeneous epidemiology and clinical presentation of HCC worldwide. However, a number of regional and national guidelines currently exist...
