Global Value Chain Participation and Firms'Responses to Exchange Rate Fluctuations

Greater participation in global value chains(GVCs)has highlighted the impact of exchange rate shocks on international trade.This paper examines how such participation influences firms'responses to exchange rate movements,focusing on the relationship between firms'pricing and value-added in exports.This study,using detailed Chinese firm-level data,demonstrates that firms with a high degree of GVC participation reacted to currency appreciation by lowering their export prices more substantially and reducing their export volumes less.This is mainly attributable to the"cost-hedging effect"within the marginal cost channel and the"pricing inhibition effect"within the markup channel.By categorizing export firms by trade models and product types,this study further demonstrates that processing trade firms at the low end of the value chain and those with low product differentiation were more inclined to absorb exchange rate shocks.This study adds to the existing theoretical framework and provides strong evidence for China in deepening GVC integration and supporting the development of high-quality export firms.

Exchange Rate Volatility： Effect on Turkish Tourism Incomes

The Turkish economy has been facing account deficit problems in recent years and tourism revenues play an important role in financing this deficit. Tourism revenues are affected by exchange rate volatility and the effects of exchange rate volatility on tourism revenues need to be researched. The purpose of this study is to examine the effects of exchange rate volatility on tourism revenues. These effects were analyzed by using multivariate co-integration model and monthly data from January 2003 to December 2011. Findings suggest that exchange rate volatility has a negative effect on tourism revenues. Additionally, a weak relationship was detected in the long term between exchange rate and tourism revenues.

Fluctuation relations for heat exchange in the generalized Gibbs ensemble

In this work, we investigate the heat exchange between two quantum systems whose initial equilibrium states are described by the generalized Gibbs ensemble. First, we generalize the fluctuation relations for heat exchange discovered by Jarzynski and Wojcik to quantum systems prepared in the equilibrium states described by the generalized Gibbs ensemble at various generalized temperatures. Secondly, we extend the connections between heat exchange and the Renyi divergences to quantum systems under generic initial conditions. These relations are applicable for quantum systems with conserved quantities and universally valid for quantum systems in the integrable and chaotic regimes.

On China’s Exchange Rate Flexibility and Stability: The More Flexible against the U.S. Dollar, the More Stable in Effective Terms

The Chinese authorities have often emphasized the importance of maintaining the renminbi＇s stable exchange rate without stating explicitly how this stability should be measured. This paper argues that the relevant concept for this stability should be in terms of the rnminbi＇s effective exchange rate, rather than its rate against any particular currency, such as the U. S. dollar. Under the current circumstances where key currencies＇ exchange rates fluctuate freely, if the authorities wish to maintain the stability of the renmnibi＇s effective exchange rate, they would want to let the renminbi＇s exchange rate fluctuate much more against the U. S. dollar than in the past because such fluctuations would greatly reduce the magnitude of the renminbi＇s fluctuations against other key currencies and thus its effective exchange rate. This point has been demonstrated by illustrative figures and by comparing the renminbi＇s hypothetical, greater exchange rate fluctuations with its actual fluctuations.
