We address the estimation of stochastic volatility demand systems. In particular, we relax the homoscedasticity assumption and instead assume that the covariance matrix of the errors of demand systems is time-varying. Since most economic and fiÂ…nancial time series are nonlinear, we achieve...

The paper explores a suitability of higher education quality measurement from student’s point of view, and analyses results of interviewing of students from engineering specialties in Perm universities. Nonlinear Principal Components Analysis (NLPCA) in interpretation of Gifi system was used...

In this paper we test for deterministic chaos in seven East European black market exchange rates, using Koedjik and Kool's (1992) monthly data from January 1955 through May 1990.

This paper considers a nonborrowed monetary base VAR and a target and instrument framework favored by the monetarists to resolve the puzzle thrownup by monetary VAR studies.

In this paper we test for deterministic chaos(i.e., nonlinear deterministic processes which look random) in seven Mont Belview, Texas hydrocarbon markets, using monthly data from 1985:1 to 1996:12 -- the markets are those of ethane, propane, normal butane, iso-butane, naphta, crude oil, and...

In this paper two types of tests are employed in investigating the convergence trends of real per capita government spending in Canadian provinces. Some signs of simple convergence were detected, with the growth of federal spending being larger in por than in rich provinces, and with Quebec...

The authors use the Backus and Kehoe (1992) long, low frequency data on real GNP/GDP and money for Australia, Canada, Denmark, Germany, Italy, Japan, Norway, Sweden, the United Kingdom, and the United States to examine the long-run neutrality and superneutrality of money propositions. In doing...

In this paper the authors estimate the degree of substitutability among the services of money, checkable deposits, savings deposits, and time deposits in a quasi-homothetic translog utility framework for Canada. The four composites mentioned are formed by aggregating more basic assets such as...
