Developing countries exhibit a more uncertain economic environment than developed countries. Argentina, Brazil and Uruguay in particular, display high levels of real exchange rate uncertainty. Moreover, a succession of trade agreements among them, culminating in the creation of Mercosur in 1991 have increased intra-regional trade. This paper examines empirically the impact of real-effective-exc...

Background: Validation studies of existing health literacy or numeracy tools among racial/ethnic minorities are limited. Objective: This study assessed the validity of the Subjective Numeracy Scale (SNS), the Diabetes Numeracy Test (DNT-5), the Brief Health Literacy Screen (BHLS), and the Short Test of Functional Health Literacy in Adults (S-TOFHLA) by trait (health literacy or numeracy) and by...

O ne of the goals of macroeconomics is to explain the aggregate sources of changes in goods' prices. If there was a single consumption good in the world, as is often assumed in models, describing the price changes of consumption would be a trivial matter. But, in reality, there are many goods and prices, and there is an important distinction between price changes that are equiproportional acros...

We discuss the relation between the absolute neutrino mass scale, the effective mass measured in neutrinoless double beta decay, and the Majorana CP phases. Emphasis is placed on estimating the upper bound on the nuclear matrix element entering calculations of the double beta decay half life. Consequently, one of the Majorana CP phases can be constrained when combining the claimed evidence for ...

During prenatal development of the cat's retinogeniculate projection, inputs from the ganglion cell axons of the two eyes are initially intermixed with each other within the lateral geniculate nucleus (LGN). As development proceeds, the inputs sort out to give rise to the eye-specific layers characteristic of the adult. During this sorting out process, individual axons undergo a stereotyped seq...

This paper presents a theory of how factor shares are determined. I first develop microfoundations for a unified aggregate production function that incorporates a frictional process of matching workers and firms. Firms with productivities drawn from a Pareto distribution hire capital and compete for workers. Wages are determined by Bertrand competition. In contrast with Houthakker’s classic res...

A number of explanations for the observed decline in GDP volatility since the mid‐1980s have been offered. Valerie Ramey and Daniel Vine (2003a, 2003b) in a couple of recent papers offer the hypothesis that a decline in the persistence of sales is an explanation for the decline in GDP volatility. Their models show that a decrease in sales persistence leads to a decline in the variance of prod...

EDITOR—Classical citrullinaemia (CTLN1) is a rare metabolic disease caused by the deficiency of argininosuccinate synthetase (ASS, E.C.6.3.4.5), which usually has its onset in neonates or young infants. These patients may present with acute onset of disturbance of consciousness and hyperammonaemia. ASS activity is very low in all tissues tested and over 30 mutations of the ASS gene have been id...
