In this paper we analyze theoretically and empirically the impact of an increase in income inequality on the current account balance. We develop a model with consumption externalities and heterogeneous agents which explains how an increase in income inequality can affect negatively or positively...

In this paper we analyze transitions in the stock markets of the US, the UK, and Germany. For all this markets we find that while the markets were focused on stocks from the IT and technology sector around the year 2000, this focus has vanished and the markets have mostly moved towards a focus...

We analyze the stock prices of the S&P market from 1987 to 2012 with the covariance matrix of the firm returns determined in time windows of several years. The eigenvector belonging to the leading eigenvalue (market) exhibits in its long term time dependence a phase transition with an order...

After the conferences in Bonn and Marrakech it is likely that international emissions trading will be realized in the near future. Major influences on the permit market are the institutional detail, the participation structure and the treatment of hot-air. Different scenarios do not only differ...

Marginal abatement cost curves (MACCs) are a favorite instrument to analyze international emissions trading. This paper focusses on the question of how to define MACCs in a general equilibrium context where the global abatement level influences energy prices and in turn national MACCs. We...

Unlike in Asia, the manufacturing sector has not (yet) become a driver of structural change in Africa. One common explanation is that the natural resource-focus of many African economies leads to Dutch disease effects. To test this argument for the case of newly found oil in Ghana we develop a...

The DART model is a multi-sectoral, multi-regional dynamic computable general equilibrium model of the world developed for the analysis of international climate policies. Since the first version of DART was developed at the Kiel Institute for World Economics in 1998, the model has undergone a...

Since the study of Ellerman and Decaux (1998) marginal abatement cost curves (MACCs) have become one of the favorite instruments to analyze the impacts of the implementation of the Kyoto Protocol and emission trading. This paper shows that the MACC in one country depends - via the link of world...

Most dynamic trade models assume steady state or balanced growth. This paper argues while this can be done in a single region model or a model without trade, the steady state assumption is problematic in a multi-regional setting with trade interactions. This paper shows the consequences of...
