Unit root tests with double trend breaks and the 1990s recession in Japan

This paper applies to Japanese macroeconomic series unit root tests that allow for the possibility of up to two endogenous break points. The presence of a single structural break around the first oil price shock in 1973 turns out to be very sensitive to the amplitude of the data sample and, in particular, it disappears when one extends the sample to the observations of the 1990s. This may indicate the presence of a second structural break, the existence of which is tested with a unit root test with a two-break alternative hypothesis for which we compute finite sample critical values. Interestingly enough, the hypothesis of the absence of a second break occurring in the 1990s can be rejected. Such results seem to indicate that the deep recession of the 1990s in Japan may not be the reflection of a negative output-gap, but that of a fall in the growth trend of output as a consequence of a huge productivity shock.

A worldwide analysis of trend in crop yields and yield variability: Evidence from FAO data

The trend in crop yields and yield variability affects food security and impact agricultural and food policies. Recent studies in this area have either focused only on one country or performed global analysis on a handful of crops. We provide the first worldwide analysis of trend and variability for 8088 country-crop yield series taken from the FAO database, employing a robust estimator to cope with the adverse statistical effects of outliers. More than half of the series display a slowdown in yield growth due to a closing of the gap between realised and attainable yields as well as to agricultural policies promoting more sustainable agricultural practices. Around one fourth of the series show also an increase in yield variability as a consequence of climate change and changes in farm management practices. Yield variability is highest in Eastern Europe, Central Asia and Middle East and North Africa, where food security may be threatened.     

影响人民币实际汇率长期趋势的因素研究

本文对人民币实际汇率的长期变动趋势进行了实证研究。通过协整模型构建了实际汇率与劳动生产率、政府消费和贸易条件之间长期的均衡关系，并通过误差修正模型考察了实际汇率短期内的动态调整过程。结果表明，无论在短期还是长期，生产率的变动对人民币实际汇率的变动都起着最重要的作用，但是对实际汇率的变动方向与巴一萨效应预测的相反。这可能是因为中国的经济发展阶段不适用其假设，劳动力的无限供给、政府消费和贸易条件等其他因素亦影响着人民币实际汇率的变动趋势，说明即使是在长期内，巴一萨效应的假设也不能成立。政府能够通过财政支出来影响实际汇率短期波动和长期变动趋势，从而影响我国产品在国际上的价格竞争优势。
