The construction of asymptotically distribution free time series model specification tests using as statistics the estimated residual autocorrelations is considered from a general view point. We focus our attention on Box-Pierce type tests based on the sum of squares of a few estimated residual...

We analyze the evolution on the design of a policy measure promoted by the Spanish Government: the Ramón y Cajal Program. In the first calls of the Program, an eligibility requirement for a researcher was a preacceptance from at least one Spanish research institution. This requirement was...

This paper analyses the power properties, under fixed alternatives, of a Wald-type test, i.e., the (Efficient) Fractional Dickey-Fuller (EFDF) test of I(1) against I(d), d1, relative to LM tests. Further, it extends the implementation of the EFDF test to the presence of deterministic trending...

Objectives. To estimate the healthcare resources spent by diabetic patients in Spain during the year 2002. Methods. The present work is a cost-of-illness study. Direct healthcare costs were estimated using rates of DM, based on primary and secondary sources of information. A range of prevalence...

We study the properties of mechanisms for deciding upon the provision of public goods when the feasible set is exogenously given (by financial and/or technological constraints), and individuals' preferences are represented by continuous, increasing and concave utility functions, and we establish...

Non-existence of a pure strategy equilibrium in a Bertrand-Edgeworth duopoly model is analyzed. The standard model is modified to include a list pricing stage and a subsequent price discounting stage. Both firms first simultaneously choose a maximum list price and then decide to lower the price,...

In this paper a consistent estimator for the Binomial distribution in the presence of incidental parameters, or fixed effects, when the underlying probability is a logistic function is derived. The consistent estimator is obtained from the maximization of a conditional likelihood function in...

The substance abuse treatment literature has basically dealt with four important questions: 1) Is treatment effective? 2) Are all programs equally effective? 3) why do programs differ in their effectiveness? and 4) which treatments are most cost-effective?. This paper reviews the substance abuse...

The purpose of this paper is to test for the presence of habit formation in consumption decisions using household panel data. We use the test proposed by Meghir and Weber (1996) and estimate the within -period marginal rate of substitution between commodities, which is robust to the presence of...

In this paper we present a model of war between two rational and completely informed players. We show that in the absence of binding agreements war can be avoided in many cases by one player transferring money to the other player. In most cases, the "rich" country transfers part of her money to...
