Convexity has long had an important role in economic theory, but some recent developments have featured it all the more in problems of equilibrium. Here the tools of convex analysis are applied to a basic model of incomplete financial markets in which assets are traded and money can be lent or borrowed between the present and future. The existence of an equilibrium is established with technique...

In the unidirectional conversion problem an on line player is given the task of converting dollars to yen over some period of time Each day a new exchange rate is announced and the player must decide how many dollars to convert His goal is to minimize the competitive ratio de ned as supE POPT E PX E where E ranges over exchange rate sequences POPT E is the number of yen obtained by an optimal o...

We have as input two portfolio of stocks managed by ING bank (North Holland). Each portfolio and each stock is described by several variables every open day of a week and during eight weeks. A portfolio is characterised by variables as its value, its performance, a stock is characterised by variable as its value, its number in the portfolio and its performance. In this paper, we study a symboli...

This paper surveys the field of financial analysis using news data, and also our own considerable work regarding movie gross analysis to show the predictive power of news data. Since the 1990s, linguistic sources such as news have been continuously proved to carry extra and meaningful information beyond traditional quantitative finance data, and thus they can be used as predictive indicators in...

Analysis of algorithms with complete knowledge of its inputs is sometimes not up to our expectations. Many times we are surrounded with such scenarios where inputs are generated without any prior knowledge. Online Algorithms have found their applicability in broad areas of computer engineering. Among these, an online financial algorithm is one of the most important areas where lots of efforts h...

Massive datasets arise in a broad spectrum of scienti$c, engineering and commercial applications. In many practically important cases, a massive dataset can be represented as a very large graph with certain attributes associated with its vertices and edges. Studying the structure of this graph is essential for understanding the structural properties of the application it represents. Well-known ...

The purpose of this paper is to analyse a fast-developing collection economic research on financial literacy. We begin with review theoretical that portrays knowledge as sort human capital investment. Indigenizing information has significant ramifications for welfare and programmes aimed at improving literacy in the general population. Then, using data from recent surveys, we determine how much...
