Climate change in game theory

The study provides an overview of the application possibilities of game theory to climate change. The characteristics of games are adapted to the topics of climate and carbon. The importance of uncertainty, probability, marginal value of adaptation, common pool resources, etc. are tailored to the context of international relations and the challenge of global warming.

Monetáris hatásosság közösségi szinten (The community level efficiency of monetary policy)

A monetáris integráció központi szereplője a Közösség jegybankja. A közös valuta értékállóságának közvetlenül fő meghatározója a jegybank. Mozgásterét azonban több tényező alakítja. E tanulmány az intézményi és stratégiai, a tagállami (decentralizált fiskális) és a pénzpiaci környezet függvényében vizsgálja az Európai Központi Bank (ECB) lehetőségeit és monetáris politikájának hatásosságát. / === / The efficiency of the European Economic and Monetary Union is a big dilemma of European applied economics. The first part introduces the monetary policy made by ECB. Rates and objectives are the framework of efficiency analysis. The second part details the common pool resource problem in the community of EMU countries, and describes the prisoner's dilemma of indebting in a currency community. The EMU practice shows free riding behavior of many member states what generally causes higher default risks. The increasing indebtedness shows dysfunction too, as the ECB must adjust the interest rate to the higher default risk which means cost premiums for fiscally disciplined countries as well. The third part analyses the efficiency of the ECB through the standards of monetary transmission. The updated criteria can explain any success or failure of the ECB in a not perfectly homogeneous community. The measures of transmission used in the study are the way of financing (banks vs. market), terms of financing, structure of the banking sector, private sector indebtedness, structure of savings and wealth, price elasticity, interest rate elasticity, wage elasticity. They show that the single monetary policy can create tension in the community not only because of the fiscal differences but also due to money market discrepancies.
