Recent research on contingent claims valuation has assumed increasingly general models of the behavior of cash securities. Relatively few attempts have been made to implement and evaluate such models empirically, however. In this paper we apply a multi-factor, continuous time pricing model to...

We consider a simple two-country model, where each country produces a consumption good from a single input. Production takes time, and the model is considered over two consecutive periods. There are three categories of economic agents, namely factor owners, entrepreneurs, and financial...

The paper discusses the dynamics of inflation and money growth in a stochastic framework, allowing for double unit roots in the nominal variables. It gives some examples of typical I(2) ’symptoms’ in empirical I(1) models and provides both a nontechnical and a technical discussion of the...

The long-run foreign transmission effects are analyzed in a multivariate time-series model of Danish and German prices, exchange rates and interest rates. The analysis of the likelihood function reveals that the vector process is I(2), but that a linear transformation of the prices and the...

The persistent movements away from long-run benchmark values in real exchange rates, dubbed the PPP puzzle, observed in many real exchange rates during periods of currency float have been subject to much empirical research without resolving the puzzle. The paper demonstrates how the cointegrated...

Some recent developments in the macroeconometric analysis of time series are discussed in the light of Haavelmo (1944). Experimental design in econometrics is discussed and related to the case of passive observation. The general ideas are illustrated with an analysis of the long-run and...

In this paper we apply the encompassing principle to test whether a model that has been estimated with seasonally adjusted data (SA) can encompass a model that is based on non-seasonllay adjusted (NSA) data. Building upon and extending the work på Ericsson, Hendry and Tran (1994) who analyze...

In this paper, we investigate the buy and sell arrival process in a limit order book market. Using an intensity framework allows to estimate the simultaneous buy and sell intensity and to derive a continuous-time measure for the buy-sell pressure in the market. Based on limit order book data...

Consistency and asymptotic normality are established for the maximum likelihood estimators in the nonstationary ARCH and GARCH models with general t-distributed innovations. The results hold for joint estimation of (G)ARCH effects and the degrees of freedom parameter parametrizing the...

Theories of economic growth hypothesize that the transition from pre-industrial stagnation to sustained growth is associated with a post-Malthusian phase in which technological progress raises income and spurs population growth while offsetting diminishing returns to labor. Evidence suggests...
