We present a non-linear solution method of saddlepoint dynamics in discrete time optimization problems. It is based on the backward attractivity of the stable manifold and is very easy to implement. After an introduction to the general method we present two applications. First we consider the...

This paper explores the determinants of alternative monetary aggregates in Euroland. A sample consisting of quarterly data covering the 1980:1-1998:4 period is considered. We are interested whether a conventionally defined money demand equation is stable in some aggregates as opposed to others....

For the sake of credibility the ECB has to commit to a clear policy strategy - a direct inflation target or an intermediate monetary target. We offer some information on the scale of control and indicator problems associated with both strategies. We estimate the links between monetary policy...

We set up an endogenous growth model with physical capital, human capital and blueprints for intermediate goods. The model can generate steady-state growth or stagnation. Along the adjustment path for a developing economy we can distinguish different stages of development. The first stage is...

This paper investigates monetary policy transmission at the microeconometric level. The credit rationing literature suggests that monetary policy has a larger effects on firms which are credit constrained. I use a large panel of German industrial firms to investigate whether this is empirically...

The purpose of this paper is to evaluate the efficiency of the East German economy at the firm level using an unbalanced panel over the transition period 1994 to 1998. We adopt a translog stochastic frontier model to estimate technical efficiency in eastern and western Germany. The results...

Corsetti, Pesetti & Roubini (1999) present a model of the Asian crisis focussed on moral hazard as a source of overinvestment. In this comment, we show that the model as stated by them does not necessarily imply moral hazard. We provide and discuss an additional assumption, which is necessary...

We analyse empirically the effect of uncertainty on the investment decisions of a sample of quoted German firms. The uncertainty measures are constructed by employing two procedures: the conventional formula of standard deviation, and the GARCH methodology. In the econometric estimates the...

Does product variety matter for export performance? This has been suggested by the new trade theory. In the present paper, we investigate empirically whether increasing export variety has contributed to the export growth of ten East Asian countries. In the paper we calculate direct measures of...
