Expectations play a central role in modern macroeconomics. The econometric learning approach, in line with the cognitive consistency principle, models agents as forming expectations by estimating and updating subjective forecasting models in real time. This approach provides a stability test for...

This paper demonstrates that the adaptive learning approach to modelling private sector expectations can be used as an equilibrium selection mechanism in a natural-rate monetary model with unemployment persistence. In particular, it is shown that only one of the two rational expectations...

I introduce Expectational Business Cycles where aggregate activity fluctuates due to learning, heterogeneous updating rules and random changes in the social norm predictor. Agents use one of two updating rules to learn the equilibrium values while heterogeneity is dictated via an evolutionary...

We embed an expectations-based optimal policy rule into a DSGE model for a small open economy that is augmented with trend extrapolation or chartism, which is a form of technical trading, in currency trade to examine the prerequisites for monetary policy. We find that a unique REE that is...

It is demonstrated in this paper that adaptive learning in least squares sense may be incapable to reduce, in a satisfactory way, the number of attainable equilibria in a rational expectations model. The model inves-tigated, as an illustration, is the monetary approach to exchange rate...

We embed different instrument rules into a New Keynesian model for a small open economy that is augmented with technical trading in currency trade to examine the prerequisites for monetary policy. Specifically, this paper focuses on conditions for a determinate, least-squares learnable rational...

We study how exploration versus exploitation innovations impact economic growth through a tractable endogenous growth framework that contains multiple innovation sizes, multi-product firms, and entry/exit. Firms invest in exploration R&D to acquire new product lines and exploitation R&D to...

The paper analyses the benefits of earmarking the environmental tax revenues in a second-best world with asymmetry of information between government and taxpayers. Taxpayers are assumed to have taste differences over consumption of an environmentally harmful activity. The government, which...

We study the interaction between private and public funding of innovative projects in the presence of adverse-selection based financing constraints. Government programmes allocating direct subsidies are based on ex-ante screening of the subsidy applications. This selection scheme may yield...

This paper uses a union bargaining framework, where the wage rate is negotiated between the representatives of employees and employers and firms unilaterally determine employment, to discuss the relationship between labour taxation and employment. In imperfectly competitive labour markets higher...
