We examine the importance of world real interest rate shocks in explaining business-cycle fluctuations in open economies using a stochastic dynamic model of a small open economy. We argue that a good proxy of the world real interest rate is not available. Moreover, the world interest rate...

I consider a method using loop variables that can limit the size of the of a rational-expectations model and hopefully speed up the process of solving it. We can generally write such a model using a "Blanchard-Kahn" specification f_t(y_t, y_{t-1}, y_{t+1}, x_t) = 0 , where y is endogenous, x is...

Recent studies of aggregate job flows in the US economy indicate that (i) specific sectoral shocks are important to account for aggregate job flows dynamics and (ii) aggregate creation and destruction dynamics display significant non-linearities. This paper aims to study whether a simple...

A reaction function, an interest rate adjustment policy, is identified that might have improved price stability and reduced economic oscillations over the past several decades. The dynamic relationship between the Federal funds rate, the CPI, and a vector of macroeconomic variables is estimated....

This paper elucidates hysteresis using a simple model of market entry and exit. A procedure for calculating hysteresis indices for economic time series is outlined. Some preliminary results assess the explanatory power of hysteresis variables in determining the equilibrium rate of unemployment...

This paper uses qualitative and quantitative methods to develop a mathematical framework for the analysis of strategic entry deterrence. Through a case study analysis, qualitative research is integrated with a pre-existing model based on game theory to gain a greater understanding of an entry...

This paper contributes to the recent literature exploring linkages between international trade, environmental degradation, and growth by bringing to the fore the dynamic gaming aspects of these issues. We use genetic algorithms (GA) to search for optimal policies in the presence of knowledge...

This paper explores the extent to which the lack of rationality of economic agents has affected the economic fluctuations and the social welfare of the U.S. hog market. A group of articles has ascribed the business cycles of the hog market, observed by economists as early as the last century,...

There is a trend in investment banking to unify pricing tools in a framework of partial differential equations. The Black-Scholes equation and its extensions are solved numerically with pde-based techniques (instead of rather heuristic techniques like Monte Carlo or Trees). The predominant...

A computational approach towards economics potentially enriches economic science beyond increasing available mathematical techniques. Computational economics (CE) can foster a viable and rich institutional economics that encourages both mathematical rigor and historical relevance while avoiding...
