We build a small open-economy model with partial financial dollarization--households hold wealth in domestic currency and a foreign currency; firms also have a balance sheet mismatch as in Gertler, Gilchrist and Natalucci (2001). The degree of dollarization is endogenous to the extent of...

VAR modelling is a frequent technique in econometrics for assumed linear processes. VAR modelling offers some desirable features such as relatively simple procedures for model specification and the possibility of making a quick and non-iterative maximum likelihood estimation of the system...

The Efficient Market Hypothesis (EMH) states that the current market price fully reflects all available information. The weak form of the EMH considers only past price data and rules out predictions based on the price data only. The prices follow a random walk, where successive changes have zero...

The paper investigates the impact of retailer's myopic behavior on the strategies and outcomes of channel members. Myopia means that the retailer disregards the evolution of the state of the system when optimizing her payoff. The channel is formed of a single manufacturer selling her product...

In applied microeconometric panel data analyses, time-constant random effects and first-order Markov chains are the most prevalent structures to account for intertemporal correlations in limited dependent variable models. An example from health economics shows that the addition of a simple...

We argue that the equation commonly used in the estimation of the wealth effect on consumption might be unsuitable for that purpose. In particular, if the usual assumptions are employed, the derivation of the equation implies that the wealth effect is indeterminate. Furthermore, it implies that...

The inability of standard intertemporal economic models under resonable values of the key parameters to generate the observed equity premium is termed as the equity premium puzzle. In order to resolve the puzzle, we propose a new approach based on worst-case analysis where agents make decisions...

This paper presents an alternative approach to understand the role of insurer in an economy with incomplete market. Based in a simple Stokey-Lucas framework. I construct a model with microstructure in the treasury bond markets with heterogenous bidders. The quantities and prices of the treasury...

A distributed system model is studied, where individual agents engage in repeated play against each other and can change their strategies based upon previous play. Similar to Dorofeenko and Shorish (2005), it is shown how to model this environment in terms of continuous population densities...

For good reasons, it is standard practice to remove trends before linearizing a growth model. This paper explores an alternative strategy that consists in computing local approximations around successive points in the state space. Obviously this is terribly inefficiant it trend removal is...
