Labour market is a complicated social and economic system, which requires the necessity to consider a number of characteristic properties (stochasticity,nonlinearity,inertance,nonstationarity) for investigation and modelling labor market processes and phenomena. In this article the problem of optimum control of a labour market is mathematically formalized. This allows for regional system of a labor market to reach desirable indicators, namely the set unemployment rate.

Construction lending risks define a special operations procedure for lender. The most important measure to construction lending risk minimization are the covenants (information and financial). The information covenants are used for minimization the hidden information (pre-contractual opportunism), and financial covenants (positive and negative) – for minimization the hidden action (post-contractual opportunism). Institutionalization of covenants as a relevant control and supervision procedure allow to reduce information asymmetry and make the construction lending process less risky and more predictable for concerned parties (agent and principal).
