This paper examines whether exporting activity matters for firm's price cost margins. The recent literature on exporting and productivity shows that exporters on average are more efficient than nonexporters. If that is the case we may also expect them to have different mark-ups. We investigate...

This paper focuses on nominal exchange rates, specifically the US dollar rate vis-à-vis the Euro and the Japanese Yen at a daily frequency. We model both absolute values of returns and squared returns using long-memory techniques, being particularly interested in volatility modelling and...

In this study we have addressed the relationship between the stock market, the measure of real economic activity (represented by the real GDP), the economic sentiment indicator, and real interest rate for the five European countries: Germany, France, Italy, the Netherlands, and the UK. We find...

This paper analyses the long-memory properties of US and European stock indices, as well as their linkages, using fractional integration and fractional cointegration techniques. These methods are more general and have higher power than the standard ones usually employed in the literature. The...

Modern OCA theory has developed different conclusions on when forming a currency union is beneficial. An important pragmatic question in this context is: Did delegating monetary policy to the ECB increase stress in the individual euro area countries? An SVAR analysis reveals that monetary stress...

In this paper, we develop a market screening model to detect inconstancies in price changes. Although there is a long history of industrial organization research of collusion, price setting behavior, and conduct - a robust model to detect structural changes in market structure was missing so...

Empirical work on price-cost margins often treats costs as exogenous. Allowing for endogenous costs when estimating price-cost margins is the topic of this paper. Methodologically, the endogenous cost model we propose leads to an additional equation that allows for the simultaneity in price...
