Persistent shifts in equilibria are likely to arise in oligopolistic markets and may be detrimental to the measurement of conduct, related markups and intensity of competition. We develop a cointegrated VAR (vector autoregression) based approach to detect long-run changes in conduct when data...

This paper analyzes the dynamic behavior of day-ahead spot prices in the German electricity spot market due to positive structural shocks in wind and solar power. It uses a dynamic structural vector autoregressive model to estimate the related structural impulse response functions. The estimates...

We develop a global vector autoregressive model to study the transmission of information between currency spot markets. Our model accounts for both simultaneous and dynamic interactions between exchange rates and order flows using historical data from the Reuters Dealing 2000 – 1 platform for...

This paper provides some test cases, called circuits, for the evaluation of Gaussian likelihood maximization algorithms of the cointegrated vector autoregressive model. Both I(1) and I(2) models are considered. The performance of algorithms is compared first in terms of effectiveness, defined as...

Intertemporal shifts in conduct, such as a transition from competitive to anticompetitive behavior, induce shifts in the firms' equilibrium price configurations. Such shifts generate non-stationary price dynamics in addition to those which originate from exogenous fundamentals. We exploit this...

The Financial Instability Hypothesis associated with Hyman Minsky has profound implications for the conduct of monetary policy in modern capitalist economies. At its core is the proposition that the central bank may contribute to the financial fragility of leveraged firms in its pursuit of...

The price puzzle is the association in a structural vector autoregression (SVAR) of a contractionary shock to monetary policy with persistent increases in the price level. Various explanations have been investigated separately in the framework of small SVARs without any common set of variables...
