Inference on ordinary unit roots, seasonal unit roots, seasonality and business cycles are fundamental issues in time series econometrics. This paper proposes a novel approach to inference on these features by focusing directly on the roots of the autoregressive polynomial rather than taking the...

The paper analyzes the transmission mechanisms of fiscal shocks in a two-country general equilibrium model with sticky prices in line with the new open economy macroeconomics (NOEM) approach. Specifically, the model allows for both market segmentation and asymmetric preferences. We introduce...

This study examines the dynamics associated with an economy implementing an Exchange Rate Based Stabilization (ERBS) programs when they are subject to sudden restrictions in international capital flows. In the context of a simple theoretical model, we describe the pressures on a country's...

In spite of the concerns about "twin deficits" (fiscal and current account deficits) for the U.S., empirical evidence suggests that “twin divergence” is a more regular feature of the data: when the fiscal accounts worsen, the current account improves and vice versa. We thus study empirically...

This paper examines the intensity of financial crises during the 1990s with a view to informing crisis prevention and mitigation policies. We compare the performance of a full Bayesian and an information-theoretic approach in addressing the econometric problems posed by the lack of a unifying...

In this paper we review the main features of the Chilean-Style of capital controls during the nineties. In particular, we analyze empirically the effectiveness of the unremunerated reserve requirement (URR) in three key areas: its capacity to open space for monetary policy, its influence on the...

Empirical evidence against both risk-sharing across countries and the uncovered interest rate parity (UIP) condition have been extensively documented. This paper investigates the empirical implications of imperfectly integrated financial markets resulting from these two issues. Under this asset...

This paper investigates the determining factors in private capital flow, differentiating foreign direct investment (FDI) from other flows and emphasizing the role of financial liberalization and. Two reasons brought about this examination. The first is the substantial increase in private capital...

Today?s level of financial integration and development of international capital markets is often compared to the pre-World War I Gold Standard. However, the propensity to currency crises seems higher today than in the past. Furthermore, the dynamics of crises has changed: In the most recent...

This paper proposes a model encompassing alternative views of contagion by highlighting the different channels of transmission of financial crises in an unifying framework. We study investor behaviour when they are affected by external habit formation. It is shown how international portfolio...
