In this paper, we develop an analytical framework for the estimation of potential output and output gaps for the euro area combining multivariate filtering techniques with the production function approach. The advantage of this methodology lies in the fact that it combines a model based approach...

This paper shows how to use optimal control theory to derive time-consistent optimal government policies in nonlinear dynamic general equilibrium models. It extends the insight of Cohen and Michel (1988), who showed that in _linear_ models time-consistent policies can be found by imposing a...

This paper aims at quantifying the economic value of knowledge spillovers by exploring information contained in patent citations. I estimate a market valuation equation for semiconductor firms during the 1980s and early 1990s, and find an average value in the amount of $0.6 to 1.2 million...

I argue that an aggregate model in which the generation of knowledge is an important factor of economic growth can be reconciled with several otherwise puzzling empirical findings on this link if knowledge affects output through investment-specific technical change. In the model, there may be a...

Artificial intelligence decision support system is always a popular topic in providing the human with an optimized decision recommendation when operating under uncertainty in complex environments. The particular focus of our discussion is to compare different methods of artificial intelligence...

Computational laboratories (CLs) are computational frameworks that facilitate the study of complex system behaviors by means of controlled and replicable experiments. CLs permit students to engage in open-ended creative research, to explore interesting questions of their own devising for which...

We study the phenomenon of spurious regression between two random variables when the generating mechanism for individual series follows a stationary process around a trend with (possibly) multiple breaks in its level and slope. We develop relevant asymptotic theory and show that spurious...

Johansen and Sornette proposes that the crash has fundamentally an endogenous origin and exogenous shocks only serve as triggering factors. This endogenous force is shown in price as power law log-periodicity (PLLP) signature prior to a crash. We estimate the highly nonlinear model developed by...

This paper examines theoretically, using a two-country real-business-cycle model, the effects of capital-market liberalization when there is limited participation in national financial markets. It is assumed that workers cannot smooth consumption as well as do stockholders, and therefore,...

This paper estimates simple regime-switching rules for monetary policy and tax policy over the post-war period in the United States and imposes the estimated policy process on a standard dynamic stochastic general equilibrium model with nominal rigidities. The estimated joint policy process...
