We analyze exchange rate volatility in the Visegrad Four countries in the course of their abandoning tight regimes for more flexible ones. We account for path dependence, asymmetric shocks, movements in interest rates, and allow for generalized error distribution. The overall findings are that...

Exchange rate stability was defined as one of the prerequisites for monetary integration in Europe. In this paper, we analyze recent developments in the volatility of exchange rates of the Central European countries (the Visegrad Group) and a selected group of European Union countries (the...

En este estudio investigamos los determinantes de las emisiones denominadas en dólares de deuda a largo plazo por parte de la banca europea. Para ello empleamos una base de datos que permite explorar los factores que, según la literatura, explican las emisiones en moneda extranjera. Incluimos...

The lognormal distribution is useful in modeling continuous random variables which are greater than or equal to zero. Example scenarios in which the lognormal distribution is used include, among many others: in medicine, latent periods of infectious diseases; in environmental science, the...

The beta distribution is useful in modeling continuous random variables that lie between 0 and 1, such as proportions and percentages. The beta distribution takes on many different shapes and may be described by two shape parameters, alpha and beta, that can be difficult to estimate. Maximum...

This dissertation consists of three essays on modeling and parameter estimation for covariance non-stationary processes. The first essay considers the non-linear deformation of time scale for G(lambda)-stationary processes developed by Jiang, Gray and Woodward [2006]. After the appropriate...

As networks improve and new services emerge, questions arise that affect service deployments and network choices. The Internet is arguably a successful example of a network shared by many services. However, combining heterogeneous services on the same network need not always be the right answer,...

This dissertation contains three essays that can be read independently. The first chapter examines how a debt crisis can occur and persist as a result of unanticipated, transitory, real interest rate and commodity price shocks. Using an optimal stopping framework, the debtor country's optimal...

This study is an empirical analysis of household expenditure behavior using the Linear and Quadratic Expenditure Systems. The expenditure systems are estimated using data collected in 1972 by the Departmento Administrativo Nacional de Estadisticas (DANE) of Bogota, Colombia. The Linear...
