The macroeconomics of near zero growth of GDP in a world of geopolitical risks and conflicts.

This paper offers an analysis of the macroeconomic conditions for near zero economic growth based on a demand-led growth model, and their implications in terms of paid employment, government finances, and the rate of profit. The main finding of the paper is that a level of net investment compatible with near zero growth would lead to a lower level of paid employment in terms of total hours worked. The effects on the distribution of work and the unemployment level would depend on changes to working time, whether in terms of average hours worked per annum, ages of entry into, and exit from, the work force.

Physiological characteristics of America's Cup sailors.

The aim of this study was to assess the physiological profile of America's Cup grinders and mastmen, by measuring energy expenditure during sailing and assessing their aerobic and anaerobic fitness. The study focused on estimating the energy used during grinding activity, by measuring oxygen uptake (VO(2)) during sail setting in real sailing conditions. In the laboratory, using an arm-cranking ergometer, we measured VO(2peak) during an incremental maximal exercise test and total energy expended during the effort and recovery phases of an all-out test that simulated grinding activity, in six grinders and mastmen and ten sailors of the same crew.
