This paper builds a model of high-frequency equity returns by separately modeling the dynamics of trade-time returns and trade arrivals. Our main contributions are threefold. First, we characterize the distributional behavior of high-frequency asset returns both in ordinary clock time and in...

Der diesjährige Nobelpreis für Wirtschaftswissenschaften ist an drei Forscher "für ihre empirische Analyse von Vermögenspreisen" verliehen worden. Zwei der Laureaten haben ganz unterschiedliche Sichtweisen auf die Funktionsfähigkeit von Finanzmärkten: Während Fama die...

In our paper we present the most important characteristics of the forint interest rate swap market, as well as examine the determinants and the information content of the forint interest rate swap spreads. The turnover of the forint interest rate swap market has grown dynamically in recent...

In our paper we present how the Hungarian credit default swap (CDS) market functions, and indicate its position in the global credit derivatives markets. Our primary goals are to glean some information from the CDS spreads about Hungary's credit risk, and to determine the role of the Hungarian...

This paper is an empirical investigation into the role of credit history in determining the spread on sovereign bank loans. It employs an error-in-variables approach used in rational-expectations-macro-econometrics to set up a structural model that links sovereign loan spreads to realized...

The purpose of this paper is to model differential rates over residual information sets, so as to shape transactional algebras into operational grounds. Firstly, simple differential rates over residual information sets are introduced by taking advantage of finite algebras of sets. Secondly,...

Although the standard trading arbitrage model provides with simple settings and adjustment mechanisms so as to take profit whenever an arbitrage opportunity comes up, empirical evidence has been piling up showing that this point of view suffers from many downsides, leaving distinctive issues...

We investigate expectation formation in a controlled experimental en-vironment. Subjects are asked to predict the price in a standard asset pricingmodel. They do not have knowledge of the underlying market equilibrium equa-tions, but they know all past realized prices and their own predictions....

A number of recent theoretical studies have explored trading in fragmented markets, e.g. Biais etal. (2000), a phenomenon increasingly witnessed in modern markets. The key assumptiongenerating the results is that there is at least one liquidity demander exploiting access to allmarkets by...

Most stock exchange regulators around the world reacted to the 2007-2009 crisis byimposing bans or regulatory constraints on short-selling. Short-selling restrictions wereimposed and lifted at different dates in different countries, often applied to different sets ofstocks and featured different...
