Entrepreneurship has been characterised as one of the most intriguing but equally elusive concepts in economics. This critical review first surveys its major intellectual roots and then proposes a modular concept of entrepreneurship that preserves its essentially distinctive behavioural,...

The paper extends the Shapiro-Stiglitz (1987) efficiency wage model by endogenising the probability of worker displacement as a function of the change in the firm's employment. This creates counter-cyclical variation in the wage mark-up and thereby generates real wage persistence. A New...

The paper modifies a standard NAIRU model by implementing "pricing-to-market" as the basic assumption for the price setting behaviour of firms in an open economy. This entirely changes the outcomes of the model: First, inflation in equilibrium is stable at any rate of unemployment; the long-run...

This paper deals with the total CO2 impact of households in a simple dynamic E3 model (economy/energy/environment), comprising a model block of private consumption and an input-output model. The consumption model describes the demand for different durables and nondurables, derived from...

With seasonal adjustment one has to decide whether to seasonal adjust an aggregate like GDP directly or to sum up its seasonally adjusted components. This choice is usually driven by subjective motives or practical convenience. In the case of seasonal adjustment with chain-linked data one might...

We raise fundamental questions about macroeconomics relevant to escaping the financial and economic crisis and shifting to a sustainable economy. First, the feasibility of decoupling environmental pressure from aggregate income is considered. Decoupling as a single environmental strategy is...

Comprehensive modelling of the impact of taxes and tax policy options requires data on the impact at micro-level of both direct and indirect taxes. There are, however, limits on the amount of data that can be gathered by any one survey. With some exceptions, most notably the Living Costs and...

We study contracting between a consumer and an expert. The expert can invest in diagnosis to obtain a noisy signal about whether a low-cost service is sufficient or whether a high-cost treatment is required to solve the consumer's problem. This involves moral hazard because diagnosis effort and...

We propose a method for conducting inference on impulse responses in structural vector autoregressions (SVARs) when the impulse response is not point identified because the number of equality restrictions one can credibly impose is not sufficient for point identification and/or one imposes sign...

In diesem Papier wird eine Konjunkturbereinigung des öffentlichen Haushaltssaldos für Deutschland vorgestellt. In den bisher am meisten verbreiteten Ansätzen wird der Konjunktureinfluss über die Abweichung des Bruttoinlandsprodukts vom Trend oder von der Normalauslastung der Wirtschaft...
