This paper employs the standard gravity model to identify the quality of governance of China's African trade partners. As a benchmark, we perform the same analysis on other major African trade partners: France, Germany, UK, and USA. Data from 53 African countries in 1996-2009 show that only China is consistently willing to import more from African countries with a lower governance standing. By doing so; China fills a gap left open by the other major world economies, and might even play a key role in the future development of Africa.

We study the impact of diverse beliefs on conduct of monetary policy. Individual belief is modeled by a state variable that defines an individual's perceived laws of motion. We use a New Keynesian Model that is solved with a quadratic approximation hence individual decisions are quadratic functions. Aggregation renders the belief distribution an aggregate state variable. Although the model has standard technology and policy shocks, diverse expectations change materially standard results about a smooth trade-off between inflation volatility and output volatility. Our main results are summed up as follows: (i) The policy space contains a curve of singularity which is a collection of policy parameters that divides the space into two sub-regions. Some trade-off between output and inflation volatilities exists within each region and some across regions. (ii) The singularity causes volatility of variables to be non monotone in policy parameters. Policymakers cannot assume a more aggressive policy will change outcomes in a predictable manner. (iii) When beliefs are diverse a central bank must also consider the volatility of individual consumption and the related volatility of financial markets. We show aggressive anti-inflation policy increases consumption volatility and aggressive output stabilization policy entails rising inflation volatility. Efficient central bank policy must therefore be moderate. (iv) High optimism about the future typically lowers aggregate output and increases inflation. This "stagflation" effect is stronger the stickier prices are. Policy response is muted since the effects of higher inflation and lower output on interest rates partially cancel each other. Effective policy requires targeting exuberance directly or its effects in asset markets. Central banks already do so with short term interventions. (v) The observed high serial correlation of 0.80 in policy shocks contributes greatly to market volatility and we show that a reduction in persistence of central bank's deviations from a fixed rule will contribute to stability. (vi) Belief dispersion is measured by cross sectional standard deviation of individual beliefs. An increased belief diversity is found to make policy coordination harder and results in lower aggregate output and lower rate of inflation. Bank policy can lower belief dispersion by being more transparent.

This article investigates the gap-filling explanation for corporate debt maturity choices in a multi-country setting. We argue that companies adjust their debt maturity in response to shocks in government debt maturity both at home and abroad; the difference between the two effects depends on the markets’ relative size and level of integration. Focusing on the European case and treating the Economic and Monetary Union as a shock in market integration, we find strong empirical support for our predictions. Our results have relevant implications for the opportunity for individual governments to use their debt maturity structure as a policy tool.
