This paper demonstrates the existence of a finite set of equilibria in the case of the indeterminacy of linear rational expectations models. The number of equilibria corresponds to the number of ways to select n eigenvectors among a larger set of eigenvectors related to stable eigenvalues. A...

This note explores the problem of aggregation with non-convex labor supply decisions in an economy with both straight time and overtime. In contrast to Hansen and Sargent (1988), the paper models this as a sequential decision. Instead of changing from one to infinity, with a sequential...

This paper estimates the contribution of Foreign Direct Investment (FDI) to the Total Factor Productivity (TFP) of Bulgaria for the period 2004-2013. Since TFP captures the joint efficiency of capital and labor, it is likely to be influenced by investments from abroad. As predicted by theory, a...

The EU is one of the three largest economies in the world. But its economy, which is still suffering from the cCOVID-19 pandemic and the negative effects of the Russian war in Ukraine, faces a bleak outlook. Inflation, or even stagflation, is a major concern as it reflects cost pressures from...

Artificial Intelligence (AI) has been embraced enthusiastically by Africans as a new resource for African development. AI could improve well-being by enabling innovation in business, education, health, ecology, urban planning, industry, etc. However, the high expectations could be little more...

Boris Johnson’s populist policy against immigrants and asylum seekers, dumped in detention camps in Rwanda, may not succeed because of legal constraints. Yet, his political agenda will probably work nevertheless, given the growing xenophobia among his electorate. Against expert advice, Home...

The uniqueness of human labour is at question in times of smart technologies. The 250 years-old discussion on technological unemployment reawakens. Frey and Osborne (2013) estimate that half of US employment will be automated by algorithms within the next 20 years. Other follow-up studies...

This paper investigates for the presence of a New Keynesian Phillips (NKPC) curve in Hungary in the period 1981:3-2006:2, following the methodology proposed by Gali and Gertler (1999). They claim that a potential source of inflation may be the sluggish adjustment of real marginal costs to...
