Hay esbozos según los cuales las probabilidades se cuentan como la fundación de la teoría matemática de las estadísticas. Mas la significación física de las probabilidades matemáticas son oscuros, muy poco entendidos. Parecíera mejor que las probabilidades físicas se fundaran en las...

We propose a novel method for the analytical approximation in local volatility models with Lèvy jumps. In the case of Gaussian jumps, we provide an explicit approximation of the transition density of the underlying process by a heat kernel expansion: the approximation is derived in two ways,...

We proposed a continuous time ARMA known as CARMA(p,q) model for modeling the interest rate dynamics. CARMA(p,q) models have an advantage over their discrete time counterparts that they allow using Ito formulas and provide closed-form solutions for bond and bond option prices. We demonstrate the...

This paper shows that the structural breaks are an important characteristic of the monthly labor force participation rate (LFPR) series of Australia, Canada and the USA. Therefore we allow for endogenously determined multiple structural breaks in the empirical specifications of fractionally...

The present paper updates the question: the study revolves to analyze the exchange rates of CNY with its major trading partners including USD, JPY, EUR, and GBP. It was assumed that CNY have a major relation with USD and in order to find out such impact, a set of observations of 2060 have been...

We show that the use of the real effective exchange rate to test for purchasing power parity, as in Astorga (2012) and other studies, introduces a bias against finding evidence of PPP. The bias is illustrated using unit root tests applied to bilateral real rates.

The present study estimates the long run private investment function for the period from 1972 to 2011 by using Johansen cointegration approach. The results suggest debt servicing, inflation and private investment to be negatively associated. The study concludes positive impact of GDP growth...

We study the phenomenon of spurious regression between two random variables,when the generating mechanism of individual series is assumed to follow a stationary process around a trend with (possibly) multiple breaks in the level and slope of trend. We develop the relevant asymptotic theory and...

In this paper, we consider some identification, estimation and specification problems in a class of semi-linear time series models. Existing studies for the stationary time series case have been reviewed and discussed. We also establish some new results for the integrated time series case. In...
