This book evaluates formally the theory of rational bubbles. A general procedure for deriving rational bubbles is provided in the first part of the book. All bubble processes discussed in literature so far could be obtained by the procedure presented. Furthermore, the set of bubble processes has...

The book offers an explanation of unemployment based on a model of wage bargaining between a trade union and an employers' association. The theoretical model emphasizes the importance of distributional fairness in wage negotiations, especially with regard to factor taxation. This is achieved by...

These notes draw from the Theory of Cointegration in order to test the monetary model of exchange rate determination. Previous evidence shows that the monetary model does not capture the short run dynamics of the exchange rate, specially when assessed in terms of forecasting accuracy. Even...

The recent labour-market performance varies greatly between the United States and continental Europe on the one hand, and between the low- and high-skilled on the other. This book starts by presenting up-to-date empirical evidence on these stylised facts and on the importance of the intensity of...

This book is about the joint dynamics of stock returns and trading volume. We propose a dynamic equilibrium model in which agents have rational expectations and are heterogeneous in their investment opportunity. The dynamics of stock returns and trading volume implied by the model can explain...

This book is motivated by the disagreement among Monetarist, Keynesian, and New Classical economists about the short-term determinants of output, unemployment, and inflation. It exposes the reader to a synthesis modeling approach which allows the derivation of the opposing theories as special...
