This paper develops a general equilibrium model with Dixit-Stiglitz preferences, monopolistic competition and rational inattention on the side of both households and firms. We show how to solve a general equilibrium model with rational inattention. We use the model to study how rational...

The area that has probably received most applications of qualitative dynamical systems is the study of business cycles and economic fluctuations. The majority of applications have employed the standard theory of bifurcations which deals with dynamical systems defined on open sets. In particular,...

Maximum likelihood estimation of structural models is regarded as computationally difficult by many who want to apply the Nested Fixed-Point approach. We present a direct optimization approach to the problem and show that it is significantly faster than the NFXP approach when applied to the...

This paper considers the nominal and real determinacy of equilibria under an exogenously specified path of interest rates in an economy in which taxation is either lump-sum or distortionary. Under lump-sum taxation, we confirm the well-known finding that equilibria display nominal...

This paper develops a general method for conducting exact small-sample inference in models which allow the estimator of the (scalar) parameter of interest to be expressed as the root of an estimating function, and which is particularly simple to implement for linear models with a covariance...

Commodity futures market efficiency has commonly been investigated in the standard I(1)-I(0) cointegration framework and it has provided inconclusive and conflicting results. However, recent empirical studies have found that the spot-futures basis is a fractionally integrated or long memory...

In this paper, we develop a modelling and computational framework that allows for the determination of optimal carbon taxes applied to electric power plants in the context of electric power supply chain (generation/distribution/consumption) networks. The adoption of carbon/pollution taxes both...

Scientists and epistemologists agree that a scientific law must be relatively simple and not contradicted by the available evidence. We propose and test one such law pertaining to international economics, the triple-parity law. It integrates three well-known equilibrium conditions, which are...

Recent tendency in academic work and at central banks is to develop and estimate large DSGE models for policy analysis and forecasting. These models typically have many shocks (e.g. Smets and Wouters, 2003 and Adolfson, Laseen, Linde and Villani, 2005). On the other hand, empirical studies...

The lion’s share of hidden Markov models (HMMs) /Markov regime switching models considered in economic research incorporates a comparably small number of states. The popularity of models with mostly two or three states principally results from their good interpretability: often regime...
