In this paper an analytical framework using robust control was developed for the one-state and one-control variable model to examine the response of the control to changes in the "free" parameter. However, in contrast to Gonzalez and Rodriguez (2003), the sign of the ``free" parameter in the...

Numerical methods are increasingly used in graduate student research. I will discuss the problems of how to teach the necessary skills and the challenges of incorporating such teaching into a graduate program

Many models of monetary policy predict a trade-off between inflation and output variance despite compelling evidence that the Federal Reserve has become more aggressive in fighting inflation and there has been a resulting decline in both inflation and output variance. We address this apparent...

This paper comparatively evaluates performances of widely-used filters employed to separate the trend of a given non-stationary time series from its cyclical components, against a Chebyshev polynomial-based filter designed for this purpose. The performances of detrending techniques under...

This paper analyses the sectoral specialisation mechanisms and their effects on growth rate differences providing an alternative approach to endogenous growth processes. The framework developed relies on a Kaldorian growth model with evolutionary micro-founded technical change. The paper...

Monetary policy is sometimes formulated in terms of a target level of inflation, a fixed time horizon and a constant interest rate that is anticipated to achieve the target at the specified horizon. These requirements lead to constant interest rate (CIR) instrument rules. Using the standard New...

Firms mainly distribute cash flows to shareholders in the form of dividends or stock repurchases. Stock repurchase has become an important method of distributing cash flows to shareholders. Firms repurchase stock for the following reasons: to distribute cash flow; to announce that firms'...

The paper investigates how the interplay between business cycles and long-run growth shapes the dynamics of economies characterized by financial market imperfections. Most of standard economic literature has centered the analysis of decentralized economies on the representative agent hypothesis...

In this paper we investigate whether macroeconomic uncertainty could distort allocation of loanable funds. To provide a road--map for our empirical investigation, we present a simple framework which demonstrates that an increase in macroeconomic uncertainty will lead to more homogeneous behavior...

We investigate the predictability of both volatility and volume for a large sample of Japanese stocks. The particular emphasis of this paper is an assessment of the performance of long memory time series models in comparison to their short-memory counterparts. Since long memory models should...
