In such wide range of social fields as natural-energy utilization and measures against natural hazard, various services may be created through investigation of correlations between various in-situ data and those obtained through meteorological turbulence simulation with horizontal resolution higher than 2km. However, most data on observation and economic movement obtained by local governments, universities, and private enterprises have not been widely distributed yet. We summarized not only hindrance factors against in-situ data distribution on both sides of providers and users but also consensus-building items to facilitate the distribution.

  The aim of the present paper is to demonstrate the establishment of the Kalecki Revolution (die Kaleckianische Wende), or Kalecki's Copernican Revolution in Kalecki (1933b), which shows that investments determine savings. This is an about face from his first theoretical study, Kalecki (1929b), which illustrates that investments are determined by savings. In the Kalecki Revolution, savings are equalized by investments in relation to income. This argument is perfectly different from that of the 'Classical' economics, in which Say's law functions and investments are equalized by savings in relation to interest rates. In this sense, the Kalecki Revolution in Kalecki (1933b), apart from Kalecki (1929b), provides the foundation for the principle of effective demand for the birth of macroeconomics, which is significant for the history of economic theory.

Using a model in which consumers’ utility is determined by consumption and savings, we show that the balanced budget multiplier is 1 even under monopolistic competition. In the second half, under the same model, we prove the existence of involuntary unemployment when government expenditure is insufficient and that involuntary unemployment is not eliminated and full employment is not automatically achieved even if the nominal wage rate and prices are flexible.
