The analysis provides a new explanation for two widespread problems concerning European unemployment policy: the disappointingly small effect of many past reform measures on unemployment, and the political difficulties in implementing more extensive reform programs. We argue that the heart of...

The industrial organization approach to banking is applied to analyze theeffects of the introduction of joint credit and interbank rate risk on the optimaldecisions on deposits and loans of a competitive bank. It is found that dueto the introduction of both sources of risk there appear direct...

A growing body of empirical evidence shows that there exists a long-run positive tradeoff between inflation and real macroeconomic activity. Within a New Keynesian framewok, we examine how increasing returns generate a positive long-run relation between inflation and output.

A major criticism against staggered nominal contracts is that they give rise to the so called persistency puzzle - although they generate price inertia, they cannot account for the stylised fact of inflation persistence. It is thus commonly asserted that, in the context of the new Phillips curve...

High-frequency financial data are characterized by a set of ubiquitous statistical properties that prevail with surprising uniformity. While these 'stylized facts' have been well-known for decades, attempts at their behavioral explanation have remained scarce. However, recently a new branch of...

Krugman's verdict that competitiveness of countries is a largely meaningless concept is a serious misjudgement of the economics profession. Countries compete for the mobile factors of production, most importantly for capital and technology. The exit-option of these factors and of firms changes...

In this paper we consider daily financial data from various sources (stock market indices, foreign exchange rates and bonds) and analyze their multi-scaling properties by estimating the parameters of a Markov-switching multifractal model (MSM) with Lognormal volatility components. In order to...
