Why does global macro economic environment become worse, it will bring many countries' unemployment rates raise as well as it can cause crime rate number rises in possible? I believe that they have case and effect relationship. In most countries, unemployment is higher today than it was in the 1960s. Why are these such large variations in unemployment, it brings more crime after 1960s? I shall indicate the reasons as below: (1)Hiring costs raise unemployment as firms become more anxious to keep the workers they have, which puts upward pressure on wages. So, when the global societies employers feel any costs are increasing after 1960s, e.g. manufacturing cost, rent cost, office and/or office electricity cost, goods transportation cost, even wage cots etc. hen, many employers will choose to dismiss many workers and unemployment rate will be raised. When many workers lose jobs for long time. Social crime number will increase, in special, the low educational and low skillful workers. Their crime mind and crime behaviors will be caused by long term unemployment.(2)Generous unemployment benefits may make workers more selective in their job search and raise unemployment. IN fact, after 1960s, global macro economic environment had been improving from manufacturing industry to service, than high technological industries development both. It will cause the developing countries, such as Africa, China, Hong Kong, Korea etc., their low education and low skillful workers lose jobs suddenly, due to their manufacturing skills won't be popular needed to employers. For example, old cloth drwssing machines will be replaced from new high technological cloth dressing machines, old car manufacturing factory method will be replaced by high technological artificial intelligent car manufacturing method. When the low manufacturing skillful workers can not find any manufacturing jobs to match their manufactury skills in their job search process. Then, in long term unemployment situation, the high technolobical development factor will cause the low manufacturing skillful workers have crime or anti-social psychological mind to cause crime behaviors easily.(3)Mismatch between worker skills and labor demand means that unemployed workers have differenties competing for jobs which will raise the level of unemployment. Similiar, due to global macro economic environment changes, e.g. many high technological skillful workers number increases, but the supply of high technological skillful workers number can not grow rapidly. So, it brings the shortage of high technological skillful labor supply. Otherwise, in global societies, many low technological skillful workers, they do not continue to learn any kinds of high technological knowledge to prepare to find any high technological jobs easily. So, global societies bring the mismatch between worker skills and labor demand. Consequently, it many bring many low technological skillful workers still lose jobs for long time, Then, their crime behaviors will also be influenced to raise in possible.(4)Lacking a well-functioning education system and active labor market policy could potentialy raise mismatch and unemployed. The reason is easy to understand. For Hong Kong example, HK crime rate is increasing after 1960s. although, HK's manufacturing industry is replaced by monetary, service industries maninly nowadays. HK lacks a well functioning education system to educate the low educational level and low skillful youngers to be trained their skills to prepare to do further high technological development industry. So, HK's social weakness is a lack of high technological jobs well-functioning education system. It can train many youngers to do high technological jobs in active labor market.
