Summary/Abstract A newly emerging area in international economics looks at the cross-correlation coefficient between past and future values of the trade balance and movement in the current exchange rate as a way of analyzing the response of the trade balance to exchange rate changes. Since the cross-correlation function follows a symmetric pattern, it comes under the heading of the S-Curve. Previous studies have considered the experience of developed and developing countries with the S-Curve, excluding China. In this paper we consider the Chinese experience. We show that when aggregate trade data between China and the U.S. are considered, there is no evidence of the S-Curve. However, when the data are disaggregated by commodity, the S-Curve is supported in almost 50% of the close to 100 industries considered. Furthermore, it appears that commodity types do not have any influence in determining the existence of an S-Curve pattern.

Twin deficits or distant cousins? evidence from India / Ratha, Artatrana   Journal Article
Ratha, Artatrana Journal Article

Summary/Abstract The twin-deficits theory has intrigued economists and policy-makers alike for the past few decades. In a Keynesian economy, budget deficit increases the absorption of the economy, causes import expansions, and thereby, worsens the trade deficit. It also causes domestic interest rates to rise, domestic currency to appreciate, and thereby, contributes to trade deficits. However, according to the Ricardian Equivalence Hypothesis (REH), rising budget deficits imply higher future tax liabilities so people would save more and consume less. As a result, an inter-temporal shift between taxes and budget deficits would have no impact on the real interest, or the trade deficit. Thus, the issue of whether the twin-deficits phenomenon holds becomes more of an empirical question, and the recent fiscal expansions to curb recession makes it timely to revisit the phenomenon, especially for the developing countries confronting both the deficits on a chronic basis. To this end, we make a case study of India, using the bounds- testing approach to cointegration and error-correction modelling on monthly and quarterly data over 1998-2009. Our results suggest that the twin-deficits theory holds for India in the short-run (validating the Keynesian channel) but not in the long-run (validating the REH).
