Exchange Rate Regimes, Trade, and the Wage Comovements
The introduction of exchange rate regimes into the standard Ricardian model of trade implies stronger positive nominal wage comovements between trading countries that fix their bilateral exchange rates. Panel regression results based on data from OECD countries from 1973 to 2010 suggest that countries in the European Monetary Union (EMU) experienced stronger positive wage comovements with their main trade partners. In comparison, the positive wage comovements between countries engaged in non-currency-union pegs were weaker. When we restrict the regression to the subsample of the EMU countries, we find a significant increase in wage comovements after these countries joined the EMU in 1999 compared to the pre-euro era.
Exchange Rate Regimes and Nominal Wage Comovements in a Dynamic Ricardian Model
We construct a dynamic Ricardian model of trade with money and nominal exchange rate. The model implies that the nominal wages of the trading countries are more likely to exhibit stronger positive comovements when the countries fix their bilateral exchange rates. Panel regression results based on data from OECD countries from 1973 to 2012 suggest that countries in the European Monetary Union (EMU) experienced stronger positive wage comovements with their main trade partners. When we restrict the regression to the subsample of the EMU countries, we find a significant increase in wage comovements after these countries joined the EMU in 1999 compared to the pre-euro era. In comparison, when the sample is restricted to the non-EMU countries, we find no evidence that non-currency union pegs affected the wage comovements
Are Financial Development and Corruption Control Substitutes in Promoting Growth?
While financial development and corruption control have been studied extensively, their interaction has not. We develop a simple model in which low corruption and financial development both facilitate the undertaking of productive projects, but act as substitutes in doing so. The substitutability arises because corruption raises the need for liquidity and thus makes financial improvements more potent; conversely, financial underdevelopment makes increased corruption more onerous and thus raises the gains from reducing it. We test this substitutability by predicting growth, of countries and industries, using measures of financial development, lack of corruption, and a key interaction term. Both approaches point to positive effects from improving either factor, as well as to a substitutability between them. The growth gain associated with moving from the 25th to the 75th percentile in one factor is 0.63-1.68 percentage points higher if the second factor is at the 25th percentile rather than the 75th. The results show robustness to different measures of corruption and financial development and do not appear to be driven by outliers, omitted variables, or other theories of growth and convergence.Financial development, growth, complementarity, corruption

Financial markets, financial dependence, and the allocation of capital
We explore one specific channel through which finance promotes growth: the allocation of capital. Using international industrial data, we find that countries with developed financial markets invest more in growing industries, and pull out more funds of declining ones. Most interestingly, this pattern is more eminent for those industries more dependent on external financing. Various robustness checks show that the results are not driven by reverse causality, omitted variables, specific countries or industries.Capital allocation Financial development Financial dependence Investment
Prussian Blue Analogue with Fast Kinetics Through Electronic Coupling for Sodium Ion Batteries
Alternative
battery systems based on the chemistry of sodium are being considered
to offer sustainability and cost-effectiveness. Herein, a simple and
new method is demonstrated to enable nickel hexacyanoferrate (NiHCF)
Prussian blue analogues (PBA) nanocrystals to be an excellent host
for sodium ion storage by functionalization with redox guest molecule.
The method is achieved by using NiHCF PBA powders infiltrated with
the 7,7,8,8-tetracyanoquinododimethane (TCNQ) solution. Experimental
and ab initio calculations results suggest that TCNQ molecule bridging
with Fe atoms in NiHCF Prussian blue analogue leads to electronic
coupling between TCNQ molecules and NiHCF open-framework, which functions
as an electrical highway for electron motion and conductivity enhancement.
Combining the merits including high electronic conductivity, open
framework structure, nanocrystal, and interconnected mesopores, the
NiHCF/TCNQ shows high specific capacity, fast kinetics and good cycling
stability, delivering a high specific capacity of 35 mAh g<sup>–1</sup> after 2000 cycles, corresponding a capacity loss of 0.035% decay
