"In December 1928, Ohlin discussed Johan �kerman�s analysis of the economic situation under the headline �Business cycle prophecies�. �kerman, who characterized the economic situation in the US as very unstable, pointed at violent speculation on the US stock market and warned against a serious crisis. Ohlin waved these fears aside: �First of all, as concerns the prospects in the US, there seems to me to be little or no reason to expect a depressive development in the year of 1929. ... It is certainly true that a minor drawback within production and trade can follow from a collapse of the stock exchange; as far as I am concerned, however, I do not think that the effects will be very profound.�"

"At the end of September 1929, Ohlin still had no feeling for the coming crisis. �There are some signs that a business cycle turning point, although possibly a very minor one, will affect America next year.� Two months later, after the great collapse of the stock exchange, he was still an optimist. The stock exchange crisis might be connected to a general business cycle downturn."

"�Our industry must expect a difficult winter, even if there is reason to expect the beginnings of a change for the better already in the spring. Even in this favorable case, a considerable part of 1931 will be characterized by a certain depression.� The question now was what kind of action the Government and the municipal authorities should take to check unemployment. Ohlin argued: �It is most likely that a more extensive public economic activity during the first stages of a recession can have a beneficial effect on production and on the labor market, even if unemployment will not be reduced to the same extent - the private sector will probably be somewhat reduced - as the increase in the number of workers in public works.�"
