    Nonlinear Intermediary Pricing in the Oil Futures Market

    We study the state-dependent trading behavior of financial intermediaries in the oil futures market, using structural vector autoregressions with Markov switching in heteroskedasticity. We decompose changes in futures price volatility into changes in the slopes of traders' demand curves and in the variability of their demand shocks. We find that the downward-sloping demand curve of intermediaries steepens ...

    The State Dependent Impact of Bank Exposure on Sovereign Risk

    The theoretical literature remains inconclusive on whether changes in bank exposure towards the domestic sovereign have an adverse effect on the sovereign risk position via a diabolic loop in the sovereign-bank nexus or reduce perceived default risk by acting as a disciplinary device for the sovereign. In this paper we empirically analyze the impact of exogenous changes in bank exposure on the risk ...

    Are There Bubbles in Stock Prices? Testing for Fundamental Shocks

    This paper investigates whether there are bubbles in stock prices. We do this using a previously studied structural vector autoregressive (SVAR) model claiming to distinguish fundamental and non-fundamental shocks to real stock prices. TheSVAR model relies on an identification restriction in order to correctly label the shocks. We test this restriction by means of a Markov switching-SVAR (MS-SVAR) ...

    Assessing the Sustainability of Government Debt: On the Different States of the Debt/GDP Process

    This paper discusses the type of trajectory a country's public debt path follows. In particular, a Markov switching ADF model is used to assess the sustainability of public debt by testing whether a government's present value borrowing constraint holds. Building on the work of Raybaudi et al. (2004) and Chen (2011), the model in this paper generalizes their methodology. The number of lags and states ...

    Structural Vector Autoregressions: Checking Identifying Long-Run Restrictions via Heteroskedasticity

    Long-run restrictions have been used extensively for identifying structural shocks in vector autoregressive (VAR) analysis. Such restrictions are typically just-identifying but can be checked by utilizing changes in volatility. This paper reviews and contrasts the volatility models that have been used for this purpose. Three main approaches have been used, exogenously generated changes in the unconditional ...

    Can Stock Price Fundamentals Properly be Captured? Using Markov Switching in Heteroskedasticity Models to Test Identification Schemes

    Structural identification schemes are of essential importance to vector autoregressive (VAR) analysis. This paper tests a commonly used structural parameter identification scheme to assess whether it can properly capture fundamental and non-fundamental shocks to stock prices. In particular, five related structural models, which are widely used in the literature on assessing stock price determinants ...

    On Using Markov Switching Time Series Models to Verify Structural Identifying Restrictions and to Assess Public Debt Sustainability: Thesis

    The first paper in this thesis deals with the issue of whether there are bubble components in stock prices. This is joint research with Wenjuan Chen (Free Universtiy Berlin). We investigate existing bivariate structural vector autoregressive (SVAR) models and test their identifying restriction by means of a Markov switching (MS) in heteroskedasticity model. We use data from six different countries ...

    The State-Dependent Trading Behavior of Banks in the Oil Futures Market

    We study the state-dependent trading behavior of financial institutions in the oil futures market, using structural vector autoregressions with Markov switching in heteroskedasticity. We consider two states of the world: tranquil and turbulent. We decompose the observable time-varying price volatility during the period 2006M6–2016M5 into changes in the slopes of traders’ demand curves and into changes ...

    On the Importance of Testing Structural Identification Schemes and the Potential Consequences of Incorrectly Identified Models

    Identification schemes are of essential importance in structural analysis. This paper focuseson testing a commonly used long-run structural parameter identification scheme claiming to identifyfundamental and non-fundamental shocks to stock prices. Five related widely used structural modelson assessing stock price determinants are considered. All models are either specified in vector errorcorrection ...
