We introduce a new point process, the dynamic contagion process, by generalizing the Hawkes process and the Cox process with shot noise intensity. Our process includes both self-excited and externally excited jumps, which could be used to model the dynamic contagion impact from endogenous and...

What is the origin of Strategic Management leading towards national Welfare planning, development and optimisation all over the World? This question opens a "Pandora's Box". It is significant that it is a key question to open up the knowledge of a world of ignorance, with some believing that...

We investigate the arbitrage-free property of stock price models where the local martingale component is based on an ergodic diffusion with a specified stationary distribution. These models are particularly useful for insurer asset-liability management as they allow the modelling of long term...

This paper develops an adjustment and projection method for input-output tables based on mathematical programming techniques. One of its main advantages is the flexibility and ability to include information relative to the elements of the table. The information considered in the adjustment...

This paper explores the ability of some popular income distributions to model observed skewness and kurtosis. We present the generalized beta type 1 (GB1) and type 2 (GB2) distributions' skewness–kurtosis spaces and clarify and expand on previously known results on other distributions'...

This paper takes a new empirical look at the longstanding question of the effect of exchange rate volatility on international trade flows by studying the case of Taiwan's exports to the United States from 1989-1998. In particular, we employ sectoral level, monthly data and an innovative rational...

Convergence of a sequence of bivariate Archimedean copulas to another Archimedean copula or to the comonotone copula is shown to be equivalent with convergence of the corresponding sequence of Kendall distribution functions. No extra differentiability conditions on the generators are needed

This study aims to analyze the series of daily prices of soybeans in the North of Parana, which includes the timeline of the years 2000 (from January) to 2011 (until October) and describe their behavior with short-term forecasts. That is, verify if the temporal dynamics of the variable is better...
