An MLE of the unknown parameters of co integrating vectors is presented for systems in which some variables exhibit higher orders of integration, in which there might be deterministic components, and in which the co integrating vector itself might involve variables of differing orders of...

The main econometric issue in testing the Lucas hypothesis (1973) in a times series context is the estimation of the variance conditional on past information. The ARCH model, proposed by Engle (1982), is one way of specifying the conditional variance. But the assumption underlying the ARCH...

We present a monetary model in the presence of segmented asset markets that implies a persistent fall in interest rates after a once and for all increase in liquidity. The gradual propagation mechanism produced by our model is novel in the literature. We provide an analytical characterization of...

This paper presents an equilibrium model for the demand and supply of liquidity and its impact on asset prices and welfare. We show that when constant market presence is costly, purely idiosyncratic shocks lead to endogenous demand of liquidity and large price deviations from fundamentals....

In this paper we argue that the relevant decision for the majority of US households is not the fraction of assets to be held in interest bearing form, but whether to hold any of such assets at all (we call this `the decision to adopt' the financial technology). We show that the key variable...

One of the current questions in the literature on the demand for money is whether the adjustment of actual to desired money holdings is in nominal or real terms. This paper describes a simple procedure than can be used to test the nominal against the real hypothesis. The test is carried out for...

The performance of empirical money demand equations over the past decade raises serious questions about money demand predictability. A variety of specifications were presented to explain past episodes of apparent money demand instability, but their success in predicting future money demand is...

Oil prices, commodity prices and American monetary policy, the last operating through a variety of channels, have all figures prominently in explanations of the international inflation process in the last 1960s and early '70s. Our major purpose in this paper is to test these various hypotheses....
