We study identification in a class of three-equation monetary models. We argue that these models are typically not identified. For any given exactly identified model, we provide an algorithm that generates a class of equivalent models that have the same reduced form. We use our algorithm to...

The authors study the prediction of latent variables in a finite mixture of linear structural equation models. The latent variables can be viewed as well-defined variables measured with error or as theoretical constructs that cannot be measured objectively, but for which proxies are observed....

We propose a continuum model for the description of buyer and seller dynamics in an Internet market. The relevant variables are the research effort of buyers and the sellers' reputation building process. We show that, if a commercial website gives consumers the possibility to rate credibly...

In this paper, the treasury rates and the credit migrations are jointly modeled by multi-dimensional affine processes. In order to capture the entire information, including credit migrations and default events, we construct non-conservative regular affine processes to model credit migrations and...

We develop a general and efficient method for valuating credit derivatives based on multiple entities in an affine framework. This includes interdependence of market and credit risk, joint credit migration and counterparty default risk of multiple firms. As an application we provide closed form...

Issues on service quality are crucial for water utility management and regulation. Omitting these aspects can lead to possible bias in estimating the efficiency of services. We integrate in a Translog cost function variables proxying this multi-dimensionality. Empirical results show that taking...

The present article intend to verify the presence of speculative rational bubbles, starting from the identification of switching regime of the returns generation process in the brazilian market exchange, BOVESPA, for the Plano Real period (July of 1994 to March of 2004). In order to achieve this...

In this paper, the interrelations between PPP and UIP are modified and tested for South Asian economies using multivariate cointegration approach. The study uses monthly data and sample period varies cross-country according to floating exchange rate regime. The results obtained are highly...

This paper addresses the place of sleep duration - objectively and subjectively - in the lives of employed men and women in Canada, based on data in Statistics Canada's 2010 General Social Survey no. 24, with an emphasis on time use. It addresses the mystery of how public opinion reflects a view...
