This paper discusses the type of trajectory a country's public debt path follows. In particular, a Markov switching ADF model is used to assess the sustainability of public debt by testing whether a government's present value borrowing constraint holds. Building on the work of Raybaudi et al....

We evaluate a recently proposed method for constructing prediction intervals, which utilizes the concept of quantile regression (QR) and a pool of point forecasts of different time series models.We find that in terms of interval forecasting of Nord Pool day-ahead prices the new QR-based approach...

En este documento se discuten los distintos factores estructurales que podrían explicar la persistencia de la inflación y se evalúan formas alternativas de calcularla. Con base en las mejores" metodologías se presenta la evolución de la persistencia tanto para el nivel como para la brecha...

En este documento se estima un modelo economé¬trico que descompone la serie de inflación trimestral anualizada entre un componente transitorio y otro permanente; este último inducido probablemente por las variaciones en la meta del Banco Central. Se concluye que la persistencia inflacionaria...

In this paper we investigate the use of forecast averaging for electricity spot prices. While there is an increasing body of literature on the use of forecast combinations, there is only a small number of applications of these techniques in the area of electricity markets. In this comprehensive...

We examine possible accuracy gains from forecast averaging in the context of interval forecasts of electricity spot prices. First, we test whether constructing empirical prediction intervals (PI) from combined electricity spot price forecasts leads to better forecasts than those obtained from...

I study the diffusion process of permanent disinflationary shocks in the Mexican economy using disaggregated price data for 283 goods across 46 cities in the period 1995-2012. I first show that the distribution of shocks shows considerable heterogeneity, with more than 80% of all cases having...

The French wholesale market is set to expand in the next few years under European pressure and national decisions. In this paper, we assess the forecasting ability of several classes of time series models for electricity wholesale spot prices at a day-ahead horizon in France. Electricity spot...

The empirical evidence behind the dynamics of high frequency based measures of volatility is that they exhibit persistence and at times abrupt changes in the average level by subperiods. In the past ten years this pattern has a clear interpretation in reference to the dot com bubble, the quiet...

Realized volatility of financial time series generally shows a slow–moving average level from the early 2000s to recent times, with alternating periods of turmoil and quiet. Modeling such a pattern has been variously tackled in the literature with solutions spanning from long–memory, Markov...
