Conclusions for Research 
I have been asked to draw some conclusions from the contributions 
for possible lines of research. Since the problem of 
unemployment involves a great part of economic theory the 
fMd is so wide that my choice will be of necessity 
subjective, but I hope not arbitrary. I shall not try to 
summarize which would be presumptive in view of the wealth 
of ideas presented. Instead I shall take my cue from various 
contributions and possibly relate them to each other. 
Some papers are general and abstract, others deal with 
the problems of our time directly. The mixture is all to the 
good. We can’t do without theory even if, as Georgescu-Roegan 
has reminded us, our concepts cannot possibly have the same 
precision as those of the physicists whom economists have 
unfortunately often tried to emulate. We might rather turn 
to Myrdal who once defined the function of theory as 
"putting questions to the empirical material". It is like 
a map which tells us where to look and what for. Without it 
we are disoriented. 
I refer first to Kregels paper on wages and unemployment 
where, following Weintraub, he uses a sophisticated non- 
neoclassical equilibrium model to deal with this problem. 
An important feature of it is that prices and quantities 
are both inclused as endogenous variables in the system. 
We are immediately reminded of Roncaglia's paper where 
we are told that the classics always dealt with the two 
sets of variables one at a time. Now as far as I know most 
applied economists when they deal with concrete problems of 
economic policy or analyse actual events follow the strategy
