Is There a Credit Crunch in the Czech Republic?
Lucie Režňáková, Svatopluk Kapounek
Acta Univ. Agric. Silvic. Mendelianae Brun. 2015, 63(3), 995-1003 | DOI: 10.11118/actaun201563030995
We apply a disequilibrium model of credit demand and supply to test the credit crunch hypothesis. We suppose that firms face credit rationing and a realised outstanding loan will be the minimum desired level of commercial bank loans and bank limit for the firm. We adopted the disequilibrium model which consists of credit supply and credit demand equations. We suggest that actual observed credit growth rate at time t lies on the supply curve (excess demand), or on the demand curve (excess supply), or on both (equilibrium). Our model is estimated by the full-information maximum likelihood approach with a numerical maximization of the likelihood function....

Acta Univ. Agric. Silvic. Mendelianae Brun. 2015, 63(3), 1023-1030 | DOI: 10.11118/actaun201563031023
Lump sum expense has special role within the Czech tax system. As the percentages of the lump sum expense used in the Czech Republic are high compared to other EU countries, they are often criticized as distortive and government searches for ways to limit their use. On the other side, the long-standing role of the lump sum expense in the Czech tax system hinders its decrease. Based on the data from the personal income tax returns of self-employed we analyze the use of the lump sum expense in the Czech Republic over the years 2004 to 2012. Using the same data and controlling for other variables, we estimate the impact of the lump sum expenses' rates...
