An extensive literature relating patients’ expectations to treatment outcomes has not addressed the determinants of these expectations. We argue that treatment history is part of a reference point that influences patients’ expectations of how effective further treatment might be, thus...

This article proposes a general class of joint and marginal diagnostic tests for parametric conditional mean and variance models of possibly nonlinear non-Markovian time series sequences. The use of joint and marginal tests is motivated from the fact that marginal tests for the conditional...

In the analysis of tax reform, when equity is traded off against efficiency, the measurement of the latter requires us to know how tax- induced price changes affect quantities supplied and demanded. In this paper, we present various econometric procedures for estimating how taxes affect demand.

We consider the problem of testing whether the observations X1, ..., Xn of a time series are independent with unspecified (possibly nonidentical) distributions symmetric about a common known median. Various bounds on the distributions of serial correlation coefficients are proposed: exponential...

McCausland (2004a) describes a new theory of random consumer demand. Theoretically consistent random demand can be represented by a "regular" "L-utility" function on the consumption set X. The present paper is about Bayesian inference for regular L-utility functions. We express prior and...

We estimate the average treatment effect (ATE) parameter and treatment on the treated (TT) for those students effectively choosing a private voucher school. With detailed individual data for both the school and the family of the student we are able to con

The modeling of the term structure of interest rates has been the focus of attention of several studies in the fields of applied and theoretical finance. Numerous models, which can be broadly classified as equilibrium models and no-arbitrage models, have

We propose a multivariate realised kernel to estimate the ex-post covariation of log-prices. We show this new consistent estimator is guaranteed to be positive semi-definite and is robust to measurement noise of certain types and can also handle non-synchronous trading. It is the first estimator...

It is known that unit root test statistics may not have the usual asymptotic properties when the variance of innovations is unstable. In particular, persistent changes in volatility can cause the size of unit root tests to differ from the nominal level. In this paper we propose a class of...
