Book Description
Univariate studies of the hypothesis of unit roots in real exchange rates have yielded consensus point estimates of the half-life of deviations from purchasing power parity of between three to five years. However, least squares-based estimates of half-lives are biased downward. Accordingly, we follow Andrews (1993) and use median-unbiased estimators of the half-life of deviations from parity as a preferred measure of the persistence of real exchange rate shocks. We study this issue using real effective exchange rate (REER) data for 22 industrial countries in the post-Bretton Woods period. Three methods of bias correction are implemented, which yield cross-country averages of half-lives of deviations from parity ranging between 4 to 15 years, with the REER of several countries displaying permanent deviations from parity.

Book Description
The term Purchasing Power Parity may date from the early twentieth century, when it was coined by the Swedish economist Gustav Cassel, but the underlying concept had been enjoying varying degrees of success since its development in sixteenth century Spain. Even towards the end of the twentieth century, and especially since the breakdown of the Bretton Woods system of fixed exchange rates, PPP and the stability of real exchange rates continued to be the subject of academic debate. This volume brings together essays covering aspects of current thinking on Purchasing Power Parity, from the various ways in which to test for its existence, to its appearance in different economies around the world, to examinations of the explanations given when PPP does not appear to hold This book was published as a special issue of Applied Financial Economics. The academic editor of this journal is Mark P. Taylor.

Book Description
We show the importance of a dynamic aggregation bias in accounting for the PPP puzzle. We prove that established time-series and panel methods substantially exaggerate the persistence of real exchange rates because of heterogeneity in the dynamics of disaggregated relative prices. When heterogeneity is properly taken into account, estimates of the real exchange rate half-life fall dramatically, to little more than one year, or significantly below Rogoff's "consensus view" of three to five years. We show that corrected estimates are consistent with plausible nominal rigidities, thus, arguably, solving the PPP puzzle.

Book Description
"Recently, Imbs et. al. (2002) have claimed that much of the purchasing power parity puzzle can be explained by 'aggregation bias'. This paper re-examines aggregation bias. First, it clarifies the meaning of aggregation bias and its applicability to the PPP puzzle. Second, the size of the 'bias' is shown to be much smaller than the simulations in Imbs et. al. (2002) suggest, if we rule out explosive roots in the simulations. Third, we show that the presence of non-persistent measurement error especially in the Imbs et. al. (2002) data can make price series appear less persistent than they really are. Finally, it is now standard to recognize that small-sample bias plagues estimates of speeds of convergence of PPP. After correcting small sample bias by methods proposed by Kilian (1998) and by So and Shin (1999), the half-life estimates indicate that heterogeneity and aggregation bias do not help to solve the PPP puzzle"--NBER website

Book Description
Between 1990 and 2001 the Argentine peso appreciated by 80 percent in real terms, and its overvaluation has been singled out as one of the main suspects in the debate on the causes of the Argentina collapse of late 2001. This paper assesses the degree of real misalignment in Argentina over the Convertibility period using a model in which the equilibrium real exchange rate is defined as the value consistent with (i) a balance of payments position where any current account imbalance is financed by a sustainable flow of international capital (external equilibrium), and (ii) traded/nontraded sector productivity differentials (internal equilibrium). Empirical implementation of the model suggests that the initial real appreciation of the peso, between 1990 and 1993, was consistent with the productivity increases that Argentina enjoyed following the stabilization of the economy after the hyperinflation of the late 1980s. But after 1996 a widening gap opened between the observed real exchange rate and that consistent with a sustainable net foreign asset position. Our estimates indicate that in 2001 the peso was overvalued by over 50 percent. The model allows us to assess how much of the overvaluation resulted from Argentina's inadequate choice of anchor currency and how much from a divergence of fundamentals between the U.S. and Argentina, ultimately due to the maintenance of policies inconsistent with the peg. We find that both factors played a role in the overvaluation accumulated between 1977 and 2001 that preceded the collapse of the Convertibility regime.

Book Description
This September 2003 issue of the Global Financial Stability Report highlights that since March 2003, further progress has been made in addressing the lingering effects of the bursting of the equity price bubble. Household and corporate balance sheets have continued to improve gradually and corporate default levels have declined. Companies in mature markets have cut costs, enhancing their ability to cope with slower growth and other potential difficulties. Corporations—particularly in the United States—have made good progress in their financial consolidation efforts and are in a better financial position to increase investment spending.

Book Description
Summarizes the for ward-looking analytical work program on macroeconomic issues related to the Poverty Reduction Strategy Paper approach. The program is evolving through a process that began with a technical workshop; participants from low-income countries, donors, academia, and civil society drafted guidance on selected issues and identified priority research topics. Partners, policymakers, and economic scholars are encouraged to share their perspectives and findings through respective team leaders, whose e-mail addresses are provided. The publication also summarizes IMF analytical work, and contains a bibliography of nearly 1,000 papers.

Book Description
There is a strong view that economics is the academic discipline that best represents the claim of positive science among social sciences. Economics has undergone significant transformations after its emergence as a science. Despite all these transformations, the feature containing positive and normative elements has not changed. While economists from the political economy tradition focus on qualitative studies that relate to other social sciences, especially political science and history, a group of economists adopt the qualitative methods of natural sciences to analyze economic problems. There is a debate among economists on how to understand social reality and what kind of science the economy should be. Business is a discipline that has declared its relative independence from economics over time. Business is a research field that encompasses a wide range of areas ranging from organizational behavior of individuals to the firm’s production and marketing strategies. This book contains articles on essential topics related to these disciplines, which have an in- separable relationship between them. Academicians contributing to the book have produced works on current topics of discussion as well as key subjects that remain important in economics and management.
