This paper seeks to understand the interplay between banks, bank regulation, sovereign default risk and central bank guarantees in a monetary union. I assume that banks can use sovereign bonds for repurchase agreements with a common central bank, and that their sovereign partially backs up any...

We build a tractable stylized model of external sovereign debt and endogenous international interest rates. In corrupt economies with rent-seeking groups stealing public resources, a politico-economic equilibrium is characterized by permanent fiscal impatience which leads to excessive issuing of...

The theory of optimal currency areas states that a currency union may succeed if the participating countries have complementary industry structures. If this is not the case a currency union does not, inevitably, have to fail because market forces will induce adjustments of the industry...

The stylized facts suggest a negative relationship between tax progressivity and the skill premium from the early 1960s until the early 1990s, and a positive one thereafter. They also generally imply rising tax progressivity, except for the 1980s. In this paper, we ask whether optimal tax policy...

While the financial protection measures enacted by the ECB and the community of Eurozone members have calmed financial markets, they have left the competitiveness problem of the Eurozone’s southern countries and France unresolved. The paper compares price inflation before the crisis with the...

This paper analyses the dynamic effects of fiscal imbalances in a given EMU member state on the borrowing costs of other countries in the euro area. The estimation of a multivariate, multi-country time series model (specifically a Global VAR, or GVAR) using quarterly data for the EMU period...

We extend “economic equivalence” results, like the Ricardian equivalence proposition, to the political sphere where policy is chosen sequentially. We derive conditions under which a policy regime (summarizing admissible policy choices in every period) and a state are “politico-economically...

We study the environmental and economic effects of public abatement in the presence of multiple stable steady-state ecological equilibria. Under shallow-lake dynamics (SLD), the isocline for the stock of pollution features two stable branches, a good and a bad one. Assuming that the ecology is...

We consider an economy where competing political parties alternate in office. Due to rent-seeking motives, incumbents have an incentive to set public expenditures above the socially optimum level. Parties cannot commit to future policies, but they can forge a political compromise where each...

We investigate the political determinants of risk premiums which sub-national governments in Switzerland have to pay for their sovereign bond emissions. For this purpose we analyse financial market data from 288 tradable cantonal bonds in the period from 1981 to 2007. Our main focus is on two...
