We address two questions about the impact of the UBS-SBC merger: (i) How will the concentration in the Swiss retail banking market change, and (ii) what are the expected consequences for the consumers. The answer to the first question is based on a comparison of Herfindahl and C3-indices in 1997...

This paper introduces a framework for analyzing the role of financial factors as a source of stability in small open economies. Our basic model is a dynamic open economy with a tradeable good produced with capital and a country-specific factor. We also assume that firms face credit constraints,...

This paper introduces a framework for analyzing the role of financial factors as a source of instability in small open economies. Our basic model is a dynamic open economy model with one tradeable and one non-tradeable good with the non-tradeable being an input to the production of the...

We analyze the effect of changes in fertility and longevity on taxes, the composition of government spending, and productivity. To that purpose, we introduce politics in an OLG economy with endogenous growth due to human and physical capital accumulation. Population ageing shifts political power...

In this paper, I investigate to what extent the cross-country variation in nominal interest rates can be explained as being due to governments' optimal response to economic conditions such as tax collection costs, tax evasion and government consumption needs. In particular, I study the effects...

This paper analyzes the influence of market discipline on the risk-taking incentives of banks. It is shown that market discipline reduces risk if banks can credibly commit to a given level of risk before the interest rate on deposits is set. If, however, the bank can readjust the level of risk...

Insuffucient monitoring by depositors, and thus a lack of market discipline, are often seen as a typical feature of banks. We show that the opposite may be the case. Banks, defined as firms that borrow from a large number of partially uninformed investors, have a tendency to be excessively...

Recent time-series evidence has re-confirmed the forecasting ability of Swiss broad money. The same money demand studies and others, however, find that the income elasticity is greater than one. Such parameter estimates are difficult to reconcile with transactions demand theory. This study...

On the eve of a major change in the world monetary system, the adoption of a single currency in Europe, our theoretical understanding of the implications of the exchange rate regime for trade and capital flows is still limited. We argue that two key model ingredients are essential to address...

This paper presents a simple model of currency crises which is driven by the interplay between the credit constraints of private domestic firms and the existence of nominal price rigidities. The possibility of multiple equilibria, including a 'currency crisis' equilibrium with low output and a...
