Abstract:
We augment the standard business cycle model with cash and credit goods a la Lucas and Stokey (1983, 1987), plus a modified cash-in-advance (CIA) considerations. In particular, the cash-in-advance constraint is extended to include private investment and government purchases. This specification is then calibrated to Bulgaria over the 1999-2020 period. The presence of cash and credit goods give a role to money in accentuating economic fluctuations. In particular, the two types of goods and the modified CIA constraint produce a more sophisticated propagation mechanism, with novel trade-offs faced by the household. The model generates too volatile consumption, and counter-cyclical investment, which are at serious odds with data. Overall, the model with cash and credit goods, and physical capital accumulation, does not provide a good framework to study business cycle fluctuations in Bulgaria.
