Large panels of variables are used by policy makers in deciding on policy actions. Therefore it is desirable to include large information sets in models for economic analysis. In this survey methods are reviewed for accounting for the information in large sets of variables in vector autoregressive (VAR) models. This can be done by aggregating the variables or by reducing the parameter space to a manageable ...

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 ...

Are capital controls and macroprudential measures successful in achieving their objectives? Assessing their effectiveness is complicated by selection bias and endogeneity; countries which change their capital-flow management measures (CFMs) often share specific characteristics and are responding to changes in variables that the CFMs are intended to influence. This paper addresses these challenges by ...

The paper analyses the global spillovers of the Federal Reserve's unconventional monetary policy measures. First, we find that Fed measures in the early phase of the crisis (QE1), but not since 2010 (QE2), were highly effective in lowering sovereign yields and raising equity markets in the US and globally across 65 countries. Yet Fed policies functioned in a procyclical manner for capital flows to ...

This paper takes a financial market perspective in examining the relationship between oil prices, the US dollar and asset prices, and it exploits the heteroskedasticity for the identification of causality in a multifactor model. It finds a bidirectional causality between the US dollar and oil prices since the early 2000s. Moreover, both oil prices and the US dollar are significantly affected by changes ...

In vector autoregressive analysis confidence intervals for individual impulse responses are typically reported to indicate the sampling uncertainty in the estimation results. A range of methods are reviewed and a new proposal is made for constructing joint confidence bands, given a prespecified coverage level, for the impulse responses at all horizons considered simultaneously. The methods are compared ...

This paper provides an empirical test of the scapegoat theory of exchange rates (Bacchetta and van Wincoop 2004, 2011). This theory suggests that market participants may at times attach significantly more weight to individual economic fundamentals to rationalize the pricing of currencies, which are partly driven by unobservable shocks. Using novel survey data which directly measure foreign exchange ...

The GARCH(1,1) model and its extensions have become a standard econometric tool for modeling volatility dynamics of financial returns and port-folio risk. In this paper, we propose an adjustment of GARCH implied conditional value-at-risk and expected shortfall forecasts that exploits the predictive content of uncorrelated, yet dependent model innovations. The adjustment is motivated by non-Gaussian ...

We investigate whether people become more willingly self-employed during boom periods or in recessions and to what extent it is the business cycle or the employment status influencing entry rates into entrepreneurship. Our analysis for Germany reveals that start-up activities are positively influenced by unemployment rates and that the cyclical component of real GDP has a negative effect. This implies ...

This paper studies the long-term impact of societal socialization on values using the example of doping behavior in sports. We apply the German Reunification Approach to the microcosm of Berlin and exploit its 40-year long division into a capitalist and a communist sector. We deliberately chose attitudes toward doping to test the impact of ideology on values since (i) post-1989 disappointed economic ...
