This paper decomposes the overall market beta of common stocks into four parts reflecting uncertainty related to the long-run dynamics of stock- specific and market-wide cash flows and discount rates. We employ a discrete time version of Merton�s Intertemporal CAPM to test whether these four...

We test whether momentum-based strategies remain profitable after considering market frictions induced by trading. Intra-day data are used to estimate alternative measures of proportional (spread) and non- proportional (price impact) trading costs. A cross-sectional model of the relation between...

Closed-end country funds trade in New York at their price. Their Net Asset Value (NAV) represent the value of the underlying assets, usually traded in each particular country. If the holders of the underlying assets have more information about local assets than the country fund holders, changes...

In this paper we present a continuous time dynamical model of heterogeneous agents interacting in a financial market where transactions are cleared by a market maker. The market is composed of fundamentalist, trend following and contrarian agents who process information from the market with...

This paper studies the time-variant interactions among US stocks, emerging market bonds and US low-grade corporate bonds. All of these assets are characterized by a similar average return, but returns are far from being perfectly correlated. Therefore, investing in these different assets...

In this paper we provide a Random-Utility based derivation of the Dirichlet-Multinomial regression and posit it as a convenient alternative for dealing with overdispersed multinomial data. We show that this model is a natural extension of McFadden's conditional logit for grouped data and show...

Good health is a crucial part of well-being but spending on health can be justified on economic grounds. The goal of reducing poverty provides a different but equally powerful case for health investments. However, if policymakers are to accelerate the substantial health gains of recent decades,...

This paper examines how demand for prescription drugs is influenced by different types of insurance. In order to understand demand characteristics and the competitiveness of pharmaceutical markets, both intermolecular (therapeutic) and intramolecular (generic) substitutions are studied in the...

The importance of the physician-patient relationship for the health care market is beyond controversy. Most theoretical work is done in a principal-agent framework, dealing with moral hazard problems. Recent work emphasizes a two-sided asymmetric information relationship between physician and...
