The question of the main determinants of persistent responses due to nominal shocks captures, at least since Chari et al. (2000), a major part of the recent macroeconomic debate. However, the question whether sticky wages and/or sticky prices are sufficient for persistent reactions of key...

This paper develops a market microstructure model with asymmetric information in order to quantify the influence which practical decision rules have on asset process. The users of practical decision rules have incomplete information at their disposal and trade in a market with both fully...

This paper analyzes the link between growth and public policy when the latter depends on economically important fundamentals. When policy is endogenous the measured effects of policy on growth will generally be biased. Using a widely quoted theoretical model, the signs of the biases are derived....

Many theoretical models show that redistribution causes low growth or capital outflows even though empirically redistribution and growth are often found to be positively associated across countries. This paper argues that tax competition and the danger of capital outflows leads optimizing...

We examine the impact of corporate currency hedging on economic stability by introducing hedging activity in a Mundell-Fleming-Tobin framework for analyzing currency and financial crises. The ratio between hedged and unhedged firms is modelled depending on firm size as well as hedging costs. The...

This paper complements research on how love of wealth bears on key variables in a Ramsey-Cass-Koopmans growth framework. It is shown that for an optimum the social planner cannot have an excessive love of wealth. If the planner has the "right" love of wealth an optimum exists and implies higher...

In this paper we present a new approach to evaluate the environmental efficiency of decision making units. We propose a model that describes a two-stage process consisting of a production and an end-of-pipe abatement stage with the environmental efficiency being determined by the efficiency of...

This study explores the reduction potential of greenhouse gases for major pollution emitting countries of the world using nonparametric productivity measurement methods and directional distance functions. In contrast to the existing literature we apply optimization methods to endogenously...
