We study a series of sustained growth models in which households' preferences are affected by the consumption of other households as summarized by average consumption. In endogenous growth models, the equilibrium paths involve lower savings and lower growth than the corresponding efficient...

This paper is a first attempt to provide a quantitative evaluation of the welfare gains resulting from the introduction of flat income taxation in Bulgaria in 2008. Using a calibrated micro-founded endogenous growth model with physical and human capital accumulation to Bulgarian data, a...

We show that in a exogenous growth model with non-market ("home") sector calibrated to Bulgarian data under the progressive taxation regime (1993-2007), the economy exhibits equilibrium indeterminacy due to the presence of non-market production. These results are in line with the findings in...

The purpose of this study is to investigate the impact of internal and external R&D on SMEs innovation performance. Micro level data was obtained from Enterprise Survey. For analysis, bivariate models have been used. The results show that internal and external R&D positively affects the product...

We conduct an event study to (1) analyze whether investors revise their expectations about a music album’s success when new chart information is published and (2) estimate how these revised expectations affect the value of a music label. We find that expectations about the success of an album...

Public agencies provide subsidies for small and medium sized businesses (SMEs) to foster their development in terms of employment and sales. Although input and output additionality have been researched intensively little is known about the actual long-term effects of subsidies on SME growth....

Few will argue with the claim that shortages are socially harmful. Shortages, by definition, imply a lack of something – not enough stuff to go around. A shortage of food implies hunger; a shortage of electricity implies darkness. But are shortages harmful to everyone equally? And if they are...

Theoretical and empirical work on innovation and firm survival has produced varied and often conflicting findings. In this paper, we draw on Schumpeterian models of competition and innovation and stochastic models of firm dynamics to demonstrate that the conflicting findings may be due to linear...

Broadband infrastructure facilitates the generation and distribution of decentralised information and ideas in a knowledge economy comprising of markets that rely on information as an input. This paper analyses the effect of broadband penetration on output per capita by estimating a static fixed...

We show that in a endogenous growth model with human accumulation calibrated to Bulgarian data under the progressive taxation regime (1993-2007), the artificial economy exhibits equilibrium indeterminacy. These results are in line with the recent findings in Chen and Guo (2015) in the context of...
