Whether labour ethic has close relationship to economic growth. I feel this issues concerns any stage of the labour life cycle and organization life cycles, it includes the link between the design of economic theory and labour individual morality and job behaviour and performance. In fact, we need to suppose all research questions and labour economy is as mapping to particular stages of an individual's life cycle to labour economy ought be related to the accumulation of human ( labour) capital, labour market entry and labour supply choices, behaviour within firms and household decision making. Prior years some researchers had been carrying on observing experiments to the women and men labour work and in whose nature environment for weeks, and then used various treatments, including manipulating the environment in such a way to increase and decrease rest periods. They got result long time working hours and not rest time, it will reduce labours( workers) of productivity. So, it implies the overall productivity and individual productivity will be reduced. Although, the employers have enough workers to work in the natural working environment at the same time, but due to who have no enough rest time to provide to them, then their workers' working performance and efficiency will be fallen. Nowadays, industrialized countries had began to consider how to plan similar welfare reforms, researching the economic reasons and consequences to labour economic issue, such as United States, the United King, Sweden and Germany, it seems economic growth and law ethic has close relationship. However, labour economy includes how to measure labour's emotion to raise productivity, as well as how technological change, education, employment and wages which can assist labour to raise productivity. Due to good labour emotion and labour ethic can raise productivity, then raising productivity can also raise economic growth finally. So, I believe which have close cause and effect relationship. However, many economists have long been pessimistic that an experimental approach could offer such illustrations of labour ethic and economic growth of cause and effect relationship in their field. Who feel labour bad emotion or bad labour ethic has no any influence to economic growth. In fact, the economic world is extremely complicated, so human needs to have economic laws is set by controlled experiment to measure or judge whether labour ethic and economic growth which has or has no any close relationship. If economists have no such test, economic laws, who can't perform such as the controlled experiments of chemists or biologists very well because who can't easily control other important factors to observe why labour emotion or ethic has reason to influence overall economic growth to any country if they neglect to carry on researching experiment between the relationship of ethic and productivity and economic growth. So I recommend economists need have participants in the natural field experiment to carry on researching to any labour emotion or ethic issue to gather statistic information of population to get prediction more accurately if who want to measure whether labour emotion or ethic and productivity which has close relationship to any country's economic growth for long term.
