Entrepreneurship development represents one of the very important factors in the development of economies in transition. Bearing in mind that most of these economies still have a significant share of agricultural products in the structure of production and exports, special attention should be paid to the development of entrepreneurship in the field of agriculture. The research results in this paper indicate that the share of entrepreneurs in this business activity in the total number of entrepreneurs is extremely low, as well as that their share in employment in state subventions is also low, and it can be concluded that entrepreneurship in agriculture is still not sufficiently developed. By using PROMETHEE and the entropy method, a comparative analysis of the performance of entrepreneurs in this sector and entrepreneurs in other business activities within the real sector of the economy was performed and it was concluded that the key limitations in the business operations of these entrepreneurs are inefficient funds management and high indebtedness.

Shadow economy is a collection of economic activities which do not contribute to one country's GDP, which the state does not have control over and which are beyond the limits of legality. In this paper, we will show the causes, manifestations, consequences and representation of the shadow economy in Serbia. Likewise, we shall talk about the problem of assessing the shadow economy, about the factors causing it and about the systematization of its advantages and disadvantages. The shadow economy is still a big problem for the domestic economy even though Serbia has decided to fight it with different measures.
