2021 Nobel Prize winner list has economic prize honor to Canadian David Card, American Joshua D. Angrist and Guido W. Imbens. The reason for Royal Society of Swiss Social Academy to their contribution in labor economy, immigration occupation and their income, and education root-cause theory of how it affect post-university income. If minimum wage does not affect the unemployment rate, then immigration select to return to labor market that increase the income by continuous work and learn. What is cause of less hiring in labor market, what is the reason that immigration could select more diversely based on their skill level from original country, and David Card uses his systematic theories to consolidate his finding. He also has all his empirical contribution to labor economic. As I have been a observing of labor market, I start realize that not easy to find a fit job if you are not receive education in Canada, especially if you are an immigration from other country. However, policy from labor market also provide continuous training and education service to those immigration. Among those immigration, many of them have a family who also increase their acceptance of one job as long as the payment is from minimum to somewhere above that. David Card has found that increase minimum wage do not cause to less hiring. Minimum wage actually meet with higher demand of job for immigration, such increasing from 11 dollar per hour to 15 dollar per hour provide more payment for works to pay for their consumer goods, such as medicine, mortgage, vehicle, therefore they are able to have saved money for their children to select a higher reputation primary school.
Nobel physics prize has been given to three scientist, Syukono Manebe, Klauss Hasalman for their work on moving the global warming forecasting of the past twenty years. He has also worked on the earth complex system with quantitative modulated model. The reason for them to receive the prize is also come from theory that they brought up from atomic to fixed star. In their interplay of disorder and fluctuation disorder in physical system from the perspective of scale changing from atomic to planetary scale. Such contribution has strongly encourage more questions about how does atomic scale disorder impact atoms energy tunnel to raise up level in the following study. What is the main cause of global warming? It is from the burning of fossil energy such as coals that result in large emission of carbon dioxide accumulating in urban area.
