Modelling nonlinearities in European money demand : an application of threshold cointegration model

Korucu Gümüşoğlu, Nebile
The money demand function has been regarded as a fundamental building block in macroeconomic modelling, as it represents the link between the monetary policy and rest of the economy. The extensive literature on money demand function is concerned with the existence of a stable money demand function, which ensures adequate prediction of impact of a given change in money supply on other economic variables such as, inflation, interest rates, national income, private investment and other policy variables. This thesis employs both linear and nonlinear estimation methods to investigate the relationship between money demand, GDP, inflation and interest rates for the Euro Area over the period 1980-2010. The aim of this thesis is to compare the European money demand in linear and nonlinear framework. First a vector autoregression (VAR) model has been estimated. Then a threshold cointegration model has been employed and nonlinearity properties of the money demand relationship has been investigated. In contrast to the existing empirical literature, linear VEC model can find evidence of stability, however it has some conflicting results which can be explained by the nonlinearity of the model. Empirical results of MTAR type threshold cointegration specification verifies the nonlinearity in European money demand. The adjustment coefficient of lower regime suggests faster adjustment towards long run equilibrium compared to upper regime in nonlinear model. Moreover, the nonlinear model presents better fit to economic literature than linear model for European money demand.


The Assessment of macroeconomic variability and monetary transmission mechanisms in Turkey with VAR esrimates
Baştan, Emine Meltem; Gaygısız Lajunen, Esma; Department of Economics (2012)
This thesis investigates the nature of macroeconomic changes by focussing on the monetary policy changes in Turkey between 1990Q1-2011Q4 and assesses the variability of the economy via impulse response functions obtained from VAR analyses. The period of the analyses is characterized with changes of the definitions of monetary aggregates in 2002 and 2007. In order to have consistent monetary series, the new and old series are constructed according to new and old definitions and then analyses are carried out ...
Analysis of the monetary stance of Turkey between 2011 and 2018 with a new monetary conditions index: the roles of government bond yields and the exchange rate
Kaptan, Savaş; Gaygısız Lajunen, Esma; Department of Economics (2019)
Measuring the monetary policy stance of central banks is a much-debated issue in the literature. The changing economic dynamics over the time and different structures of economies have made impossible to use only short term interest rates, monetary aggregates or money market rates for analyzing the monetary stance. Accordingly, comprehensive monetary conditions indexes have been discovered and some central banks have started to use them as an operational target. In line with these developments, the main aim...
Modeling co-movements among financial markets: applications of multivariate autoregressive conditional heteroscedasticity with smooth transitions in conditional correlations
Öztek, Mehmet Fatih; Öcal, Nadir; Department of Economics (2013)
The main purpose of this thesis is to assess the potential of emerging stock markets and commodity markets in attracting the attention of international investors who utilize various portfolio diversification strategies to reduce the cumulative risk of their portfolio. A successful portfolio diversification strategy requires low correlation among financial markets. However, it is now well documented that the correlations among financial markets in developed countries are very high and hence the benefits of i...
Optimal monetary policy and the timing of asset trade in open economies
Senay, Ozge; Sutherland, Alan (2007-05-01)
This paper analyses the timing of asset trade and its implications for monetary policy and welfare in open economies. Optimal policy is shown to differ significantly depending on whether asset trade takes place before or after policy decisions are made.
An Investigation on the nature of the idiosyncratic risk of stock portfolios
Kocaarslan, Barış; Soytaş, Uğur; Department of Business Administration (2018)
In this study, based on sound economic theories, two economic transmission channels are identified to investigate the impacts of changes in funding liquidity conditions in interbank loan markets and the reserve currency (US dollar) value on the idiosyncratic portfolio-level risks. Controlling for business cycles, we find that a deterioration in funding liquidity conditions increases the idiosyncratic risk of high-risk portfolios more than that of less risky portfolios. This increase is stronger when the idi...
