This paper estimates the relationship between the choice of website and the characteristics of the individual making this choice. What explain consumer website choice and is this consumer loyal to the same website? This paper approaches this question by modelling individual’s website...

This paper describes a way of recording information on discrete states by means of a technique called key transformation. This involves recognising that, where N discrete states of a variable are observed T groups or periods, any particular combination of states and periods can be uniquely...

I use the automated search algorithm to address practical issues that arise in estimating income and price elasticities for U.S. trade in services: specification of dynamics, specification of the search strategy, simultaneity biases, and aggregation biases. Specifically, starting from a general,...

For univariate time series we suggest a new variant of efficient score tests against fractional alternatives. This test has three important merits. First, by means of simulations we observe that it is superior in terms of size and power in some situations of practical interest. Second, it is...

In this paper we attempt to provide evidence on the structure of technology in the three industrial branches of French economy, when capital is treated as quasi-fixed input. However instead of choosing a single functional form as an approximation to the variable cost function, modified versions...

We present a multivariate generalization of the simple markov-switching model. We allow for the introduction of several latent processes that have a simple parametric distribution. The matrix-variate bernoulli distribution yields a flexible yet parsimonious pattern of dependence between the...
