The paper presents univariate and panel unit root tests for gasoline and oil price convergence over the last decade. We test for the absolute versus relative version of the law of one price (LOOP) and estimate the speed of convergence as well as its development over time. Our results show that...

We empirically analyze convergence of European producer and consumer prices for diesel fuel and investigate the role of excise taxation. By comparing the speed of convergence of prices and taxes we find a surprisingly fast speed of convergence for consumer prices. While this can in part be...

In this paper, we revisit the association between happiness and inequality. We argue that the perceived fairness of the income generation process affects this association. Building on a two-period model of individual life-time utility maximization, we predict that persons with higher perceived...

Using a new dataset for 41 German non-governmental organizations (NGOs), we analyze the allocation of NGO aid across recipient countries in a Tobit regression framework. By identifying for each NGO the degree of public refinancing, we address the largely unresolved issue of whether financial...

Major DAC donors are widely criticized for weak targeting of aid, selfish aid motives and insufficient coordination. The emergence of an increasing number of new donors may further complicate the coordination of international aid efforts. On the other hand, new donors (many of which were aid...

We examine whether and under which circumstances World Bank projects and IMF programs affect the likelihood of major government crises. Using a sample of more than 90 developing countries over the period 1970-2002, we find that crises are on average more likely as a consequence of Bank and Fund...

The paper develops a theoretical model showing a mutual relationship between corruption and capital account restrictions. According to the model, higher corruption induces stricter restrictions and vice versa. We test the model using panel data for 112 countries over the period 1984-2002 and...

We investigate whether temporary members of the UN Security Council receive favorable treatment from the World Bank, using panel data for 157 countries over the period 1970-2004. Our results indicate a robust positive relationship between temporary UN Security Council membership and the number...

The paper analyzes the impact of decentralization on governance employing four indicators of governance and five measures of decentralization. Depending on data availability, crosssections for a maximum of 129 countries are estimated. Results for a panel of about 70 countries over the period...

We investigate whether temporary members of the UN Security Council receive favorable treatment from the IMF, using panel data for 191 countries over the period 1951 to 2004. Our results indicate a robust positive relationship between temporary UN Security Council membership and participation in...
