This article provides an axiomatic characterization of quasi-hyperbolic discounting and a more general class of semi-hyperbolic preferences. We impose consistency restrictions directly on the intertemporal trade-offs by relying on what we call ''annuity compensations.'' Our axiomatization leads naturally to an experimental design that disentangles(More)
The endogenous opioid receptor-like1 (ORL1) ligand, nociceptin/orphanin FQ (FGGFTGARKSARKLANQ), a heptadecapeptide structurally resembling dynorphin A, has recently been identified. The wide distribution of ORL1 mRNA and nociceptin/orphanin FQ precursor in the CNS, particularly in the limbic system regions and in several areas known to be involved in pain(More)
Betaglycan is an accessory receptor of members of the transforming growth factor-beta (TGF-beta) superfamily, which regulates their actions through ligand-dependent interactions with type II receptors. A natural soluble form of betaglycan is found in serum and extracellular matrices. Soluble betaglycan, prepared as a recombinant protein using the(More)
We have demonstrated previously that ectopic expression of a soluble betaglycan, also known as transforming growth factor (TGF) beta type III receptor, can suppress the malignant properties of human carcinoma cells by antagonizing the tumor-promoting activity of TGF-beta (A. Bandyopadhyay et al., Cancer Res., 59: 5041-5046, 1999). In the current study, we(More)
In this paper, the problem of estimating from a finite set of measurements of the radar remotely sensed complex data signals, the power spatial spectrum pattern (SSP) of the wavefield sources distributed in the environment is cast in the framework of Bayesian minimum risk (MR) paradigm unified with the experiment design (ED) regularization technique. The(More)
The Newey and West (1987) estimator has become the standard way to estimate a het-eroskedasticity and autocorrelation consistent (HAC) covariance matrix, but it does not immediately apply to time series with missing observations. We demonstrate that the intuitive approach to estimate the true spectrum of the underlying process using only the observed data(More)
In this paper, a general framework is proposed for the use of (quasi-) experimental data when choosing policies such as tax rates or the level of inputs in a production process. The data are used to update expectations about social welfare as a function of policy, and the policy is chosen to maximize expected social welfare. We characterize the properties(More)
This paper presents theoretical results and a computational algorithm that allows a practitioner to conduct hypothesis tests in nonstandard contexts under which the null hypothesis is characterized by a finite number of inequalities on a vector of parameters. The algorithm allows one to obtain a test with uniformly correct asymptotic size, while directing(More)
