The present article suggests a holistic framework for defining, evaluating and improving the governance of agroecosystem services in Bulgaria. The interdisciplinary Theory of Ecosystem Services and the New Institutional Economy are adapted, and an attempt made to define the governance of agroecosystem services, to identify its agents, forms and mechanisms, to formulate an adequate criterion for evaluating its efficiency, and to characterize the stages for its analysis and improvement. The proposed new approach is based on the building up of a hierarchy of agroecosystems and services related to its different levels, as well as an assessment of the system of governance that corresponds to each level of provision of agroecosystem services.

This research aims to visualize the "impossible trilemma", i. e. the impossibility of simultaneously having a fixed exchange rate, free movement of capital and an independent monetary policy, for every economy through the application ofartificial intelligence software. The advantages of visualization techniques are revealed. The explored countries are divided into the following panels: theEurozone countries, the developed European countries (DEC), the developed non-European countries (DNEC), the BRICS countries (Brazil, Russia, India, China and South Africa), the developing European countries and the Organizationof the Petroleum Exporting Countries (OPEC). The results of the research show a great level of confirmation of the trilemma for the developing economies and the developed non-European countries. This implies that there is a compromise between exchange rate stability, monetary independence, and free capital mobility.

The goal of this research is to find out what determines monetary conditions in Bulgaria under a currency board arrangement – the automatic adjustment mechanism of the orthodox currency boards or discretionary policies of the government and the central bank. A time series vector autoregression for the period 1998-2018 is employed in order to investigate the impact of the fiscal reserve and the minimum required reserves of the commercial banks on the monetary base, the interbank interest rate, the money supply and the inflation rate. The empirical results indicate that the automatic adjustment mechanism does not function under the Bulgarian currency board but the policies of the government and the central bank have a discretionary effect on monetary conditions in the country.
