In this paper we develop a model for the conditional inflated multivariate density of integer count variables with domain Zn. Our modelling framework is based on a copula approach and can be used for a broad set of applications where the primary characteristics of the data are: (i) discrete...

In this paper we propose a model for the conditional multivariate density of integer count variables defined on the set Zn. Applying the concept of copula functions, we allow for a general form of dependence between the marginal processes which is able to pick up the complex nonlinear dynamics...

Much of the trading activity in Equity markets is directed to brokerage houses. In exchange they provide so-called quot;soft dollarsquot; which basically are amounts spent in quot;researchquot; for identifying profitable trading opportunities. Soft dollars represent about USD 1 out of every USD...

One of the main results of the literature on the effects of uncertainty on trade states that uncertainty should not matter in the presence of well developed forward markets. Empirical studies, however, do not support this result. We derive the demand for forward cover in a small open economy...

There is a huge literature on the effects of uncertainty on trade levels. One very strong result of that literature is that uncertainty should not matter, as long as well developed forward markets exist. The empirical implications of this result, however, are hard to find in the data. We model...

In this paper, we examine the reaction of stock market returns and volatility in a diverse group of six emerging markets to a set of IMF events. In particular, we test within a panel framework whether there was an “investor panic” causing a significant drop in stock market returns on the...
