The purpose of this thesis is to shed more light in the FX market microstructure by examining the determinants of bid-ask spread for three currencies pairs, the US dollar/Japanese yen, the British pound/US dollar and the Euro/US dollar in different time zones. I examine the commonality in liquidity with the elaboration of FX market microstructure variables in financial centres across the world (New York, London, Tokyo) based on the quotes of three exchange rate currency pairs over a ten-year period. I use GARCH (1,1) specifications, ICSS algorithm, and vector autoregression analysis to examine the effect of trading activity, exchange rate volatility and inventory holding costs on both quoted and relative spreads. ICSS algorithm results show that intraday spread series are much less volatile compared to the intraday exchange rate series as the number of change points obtained from ICSS algorithm is considerably lower. GARCH (1,1) estimation results of daily and intraday bid-ask spreads, show that the explanatory variables work better when I use higher frequency data (intraday results) however, their explanatory power is significantly lower compared to the results based on the daily sample. This suggests that although daily spreads and intraday spreads have some common determinants there are other factors that determine the behaviour of spreads at high frequencies. VAR results show that there are some differences in the behaviour of the variables at high frequencies compared to the results from the daily sample. A shock in the number of quote revisions has more effect on the spread when short term trading intervals are considered (intra-day) compared to its own shocks. When longer trading intervals are considered (daily) then the shocks in the spread have more effect on the future spread. In other words, trading activity is more informative about the future spread when intra-day trading is considered while past spread is more informative about the future spread when daily trading is considered

The literature on bond markets and interest rates has focused largely on the term structure of interest rates, specifically, on the so-called expectations hypothesis. At the same time, little is known about the nature of the spread of the interest rates in the money market beyond the fact that such spreads are generally unstable. However, with the evolution of complex financial instruments, it has become imperative to identify the time series process that can help one accurately forecast such spreads into the future. This article explores the nature of the time series process underlying the spread between three-month and one-year US rates, and concludes that the movements in this spread over time is best captured by a GARCH(1,1) process. It also suggests the use of a relatively long term measure of interest rate volatility as an explanatory variable. This exercise has gained added importance in view of the revelation that GARCH based estimates of option prices consistently outperform the corresponding estimates based on the stylized Black-Scholes algorithm.

We uncover high persistence in credit spread series that can obscure the relationship between the theoretical determinants of credit risk and observed credit spreads. We use a Markovswitching model, which also captures the stability (low frequency changes) of credit ratings, to show why credit spreads may continue to respond to past levels of credit risk, even though the state of the economy has changed. A bivariate model of credit spreads and either macroeconomic activity or equity market volatility detects large and significant correlations that are consistent with theory but have not been observed in previous studies. © 2010 Nova Science Publishers, Inc.

Az államoknak nyújtott hitelekre gyakran gondolunk biztonságos befektetésként, lehetetlen vagy legalábbis valószerűtlen kimenetelként kezelve az államcsőd lehetőségét. Pedig államcsődök azóta vannak, amióta szuverén államok hitelt vesznek fel, és még csak nem is ritka eseményekről van szó. Amikor egy-egy válság vagy csődesemény felhívja erre a figyelmünket, a leggyakrabban elhangzó kérdés az, hogy miért következett be a csőd. Ebben a tanulmányban a szerző ennél furcsább kérdésre hívja fel a figyelmet: mi késztet egy hitelt felvevő államot arra, hogy visszafizesse hiteleit, vagyis miért nem megy csődbe? Ez rögtön felvet egy további, talán még meglepőbb problémát: miért kap egyáltalán egy szuverén állam hitelt? Ezekre a kérdésekre már régóta tudni véljük a választ: azért, mert az államcsődnek költségei vannak. A lehetséges költségek és a hozzájuk kapcsolódó empirikus kutatások értelmezésével és rendszerezésével, az ellentmondások feltárásával azonban a szerző felhívja a figyelmet arra, hogy bár elképzeléseink vannak és lehetnek, valójában nem ismerjük a törlesztést kikényszerítő és így az államadósságok létezését biztosító mechanizmusokat. Talán éppen azért nem, mert az államcsőd lehetséges politikai, gazdasági következményei - azaz költségei - idővel legalább annyira változnak, mint öltözködési, étkezési és közlekedési szokásaink. ____ Loans to sovereign states are often referred to as safe investments, treating default as an impossible or at least improbable event. Yet sovereign defaults have been arising ever since countries borrowed money. They are not rare at all. When a debt crisis or default event draws attention to the problem, the commonest question put is why defaults occur. This paper stresses the need to ask a less common question as well: why sovereign states repay loans, why they do not default. Consequent on that is why rational lenders give money to countries. The answer to these questions seems to be because defaults are costly. The paper reviews and systematizes possible cost types and explores inconsistencies in the related literature, to show that the mechanisms supporting the existence of sovereign debts are not precisely known. One reason why costs of defaults are challenging to study may be that the possible political and economic consequences of defaults change over time.
