We propose a novel approach to model serially dependent positive-valued variables which realize a non-trivial proportion of zero outcomes. This is a typical phenomenon in financial time series observed on high frequencies, such as cumulated trading volumes or the time between potentially...

The purpose in this letter is first to review briefly the empirical results on the relationship between real interest rates and real exchange rates; this empirical literature provides little support for the hypothesis of Roll that expected real interest rates are equal in general. Our second aim...

This paper develops a method to improve the estimation of jump variation using high frequency data with the existence of market microstructure noises. Accurate estimation of jump variation is in high demand, as it is an important component of volatility in finance for portfolio allocation,...

In this paper, we used the GARCH (1,1) and GARCH-M (1,1) models to investigate volatility and persistence at daily frequency for European and US financial markets. In the study we included fourteen stock indices (twelve Europeans and two Americans), during March 2013 - January 2017. The results...

The growth of peer-to-peer exchanges and the blockchain technology has led to a proliferation of cryptocurrencies and to a massive increase in the number of investors who actually negotiate digital money. Cryptocurrencies trade at prices which is mainly driven by investor sentiment, becoming a...

We elaborate on a new distributional scheme resulting from the generalized Pearson distribution with application to financial modelling. As case studies we consider the major historical indices daily returns, DJIA, NASDAQ composite, FTSE100, CAC40, DAX and S&P500, as well as, high-frequency...

The purpose of this study was to investigate direct effects of capital inflow, financial deepe- ning on economic growth in Nigeria due to diverse contentions it stirred among researchers from 1981 to 2018 using the Autoregressive Dis- tributive Lag (ARDL) co-integration approach. The findings...

This study looks at the interrelationship between fiscal policy and safe assets as there is surprisingly little analysis about this beyond fleeting references. The study argues that from a certain point more public debt will not "buy" more safety: countries face a kind of "safe-assets Laffer...

This paper explores the link between default risk and fiscal procyclicality. We show that countries with higher sovereign risk have a more procyclical fiscal expenditure policy, which is driven mostly by transfers. We build a small open economy model with income inequality, social transfers, and...
