Earlier the first author built an oligopolistic model of the American automobile firms, demonstrating the possibility of econometric model building at the firm level. In the present paper, on the basis of detailed corporate data, we advance this effort further using a more elaborate behavioral...

The analysis of Tobit model with non-normal error distribution is extended to the case of asymmetric Laplace distribution (ALD). Since the ALD probability density function is known to be continuous but not differentiable, the usual mode-finding algorithms such as maximum likelihood can be...

From July 1978 to April 1989 Taiwan adopted a snake system by allowing the foreign exchange rate to fluctuate within a narrow band of the centered rate. Using monthly data on the Taiwan dollar/U.S. dollar exchange rate, we show that inference on the purchasing power parity hypothesis is...

We develop a new Markov Chain Monte Carlo procedure for a time series regression model truncated by upper and lower bounds. The regression error term is assumed to follow an ARMA--GARCH process. We use a convergence diagnostics with a simultaneous test of mean and covariance stationarity and...

Advertising expenditures may well be regarded as a form of investment. Using this concept, Nerlove and Arrow examined an optimal advertising policy for the firm which maximizes present valued cash flow. In this paper the Nerlove-Arrow model is applied by use of the usual stock adjustment formula...
