I am a Ph.D. Candidate in Economics of the Quantitative Economics Doctorate (QED) at the University of Alicante (Spain).
My research is focused on the empirical analysis of real and nominal
exchange rates. In my dissertation I applied modern time series
econometric techniques to explain and forecast the behavior of exchange
rates, both in developed and underdeveloped economies. Recently, I am
studying also themes in empirical finance, specifically I am trying to
understand the recent stock market crisis in the US.
I expect to obtain my Ph.D. by June 2009. My Ph.D. Thesis is titled
"Three Econometric Essays on Exchange Rates", and my advisor is Prof. Gabriel Pérez-Quirós, currently at the Research Divission of the Bank of Spain.
My teaching interest are in macroeconomics, international finance, and
econometrics. However, I can also teach courses in other fields if
needed. | |

Argentinean Real Exchange Rate 1900-2006:
Testing Purchasing Power Parity Theory, Estudios de Economia, Vol. 35, No. 1, June, pp. 33-64
Abstract This
paper tests the Purchasing Power Parity Theory of Exchange Rates
dealing with Argentinean data for the period 1900-2006. Since most
works study developed countries or developing countries but with short
span data, this paper aims to fill a gap in the wide PPP literature by
studding a developing country with a long-run approach. This country is
particularly interesting since during 20th century "Argentine economic
performance tells a story of decline unparalleled in modern times"
(Taylor 1992). The downfall of this once developed country has probably
affected the behavior of its RER and the validity of PPP. To check
this, we use a wide set of econometric techniques and found that the
PPP theory is not verified in Argentina, since its RER appears as a
non-stationary variable, and there is no evidence of cointegration
between the nominal exchange rate and the relative prices. In
particular, the Argentinean RER appears to be trend-stationary under
structural breaks with a continuous real depreciation of the
Argentinean currency, especially in the first half of XX century, which
is consistent with theories that relate the secular impoverishment of a
country with the depreciation of its RER, as the Balassa-Samuelson
effect.

Short-Run Forecasting of the Euro-Dollar Exchange Rate with Economic Fundamentals (with Maximo Camacho and Gabriel Pérez-Quirós)
Abstract An
extensive literature has shown the difficulty in explaining and
forecasting short-run exchange rate changes using economic
fundamentals. While in-sample results are sometimes good, out-of-sample
researchers usually cannot beat a simple random walk model. We propose
here a fundamentals-based econometric model for the weekly changes in
the Euro-Dollar rate with the distinctive feature of mixing variables
quoted at different frequencies. We show that our model obtains good
in-sample results, but, more importantly, out-of-sample we obtain a
slight improvement upon the simple random walk model using traditional
statistical measures of forecasting error, and a great improvement with
the direction of change measure, which has much more economic
importance. With this metric, our model performs much better than the
random walk at all forecasting horizons, being these improvements
statistically significant.

Latin American Real Exchange Rate Misalignments Under Regime Shifts: What Drives the Changes in States?, master thesis paper
Abstract This
study analyzes for Argentina, Brazil and Mexico whether the
misalignments from the Equilibrium Real Exchange Rate are subject to
changes in regime and what drives these changes, using the Markov
Regime Switching model with Time-Varying Transition Probabilities. This
work is motivated by the experience of Latin American countries that
alternate periods of appreciated RER, as when the exchange rate is used
as the nominal anchor to reduce inflation, and periods of depreciated
RER, as when exchange rate policies are pursued to improve the
country's competitiveness; as documented in several case-studies that
ad-hoc recognizes these episodes and relate them to stabilization plans
or other factors. Our aim is to find a statistical method that
endogenously identifies the regimes and allow us to study why they
occur and change in those countries to test the findings of the
case-study works. Results confirm the existence of two persistent
states in the mean of those countries' real misalignments associated
with appreciation and depreciation situations. The variables that
explain the changes in the transition probabilities are local such as
inflation rate, and international like US interest rate. Hence, some
conclusions on the determinants of appreciations and depreciations are
obtained.
