We propose a Bayesian methodology that enables banks to improve their credit scoring models by imposing prior information. As prior information, we use coefficients from credit scoring models estimated on other data sets. Through simulations, we explore the default prediction power of three...

In this paper we consider bayesian semiparametric regression within the generalized linear model framework. Specifically, we study a class of autoregressive time series where the time trend is incorporated in a nonparametrically way. Estimation and inference where performed through Markov Chain...

This paper extends the analogy previously established by Leamer (1978a), between a Bayesian inference problem and an economics allocation problem, and shows that posterior modes can be interpreted as optimal outcomes of a bargaining game. This bargaining game, over a parameter value, is played...

This paper identifies a subset of emerging markets that have higher than average expected returns and studies risk properties of this subset by investment simulations. It is found that: (1) the portfolio of "value" emerging markets generates superior returns, and (2) statistical measures of its...

The study examines the reasons for financial crises in 31 emerging market countries during 1980-2001. It estimates a probit model using 23 macroeconomic and financial sector variables. Traditional variables such as unemployment and inflation, as well as several indicators of indebtedness such as...

This paper develops and estimates an unobserved components model for purposes of monetary policy analysis and inflation targeting in a small open economy. Cyclical components are modeled as a multivariate linear rational expectations model of the monetary transmission mechanism, while trend...

Upon winning the 2002 presidential elections, event that considerably increased the Brazilian country risk levels and volatility, Lula celebrated by declaring: “hope has beaten fear”. Extending Une and Portugal (2004), the aim of this paper is twofold: to empirically test the interrelations...

In this paper we extend the macroeconometric model developed in Bagnai (2004) by linking it to a submodel for the Japanese economy, and we utilize this extended model to investigate several hypotheses of reduction in the US twin deficits. The Japanese submodel is specified and estimated along...

An important factor that helps distinquish between alternative balance of payments theories is the assumed causal relationship between the domestic credit and reserve components of a country's monetary base. This paper reports test results of this causal relationship in Austrailia, Belgium,...

Indicators of financial crisis generally do not have a good track record. This paper presents an early warning system (EWS) for six countries in Asia in which indicators do work. Our binary choice model, which has been estimated for the period 1970:01–2001.12, has the following features. We...
