The effect of public investment on economic growth is a crucial public policy issue. Empirical research into this question was stimulated by Aschauer (1989), who suggested that public capital has a powerful impact on the productivity of private capital.Aschauer's results were controversial and...

A large body of evidence suggests that poor countries tend to invest less (have lower PPP - adjusted investment rates) and to face higher relative prices of investment goods. It has been suggested that this happens either because these countries have lower TFP in the investment - good producing...

Central to the scientific debate about the 'informal sector' and the validity of the concept used to be a twofold challenge. The crux laid not only in the objective to explain the widely visible persistence of the informal economy in developing countries, but also in the identification of its...

Recent studies have found that resource-rich low-income countries are better off investing their resource revenues domestically rather than saving them abroad in a sovereign wealth fund (SWF). This paper finds an optimal rule-based policy of accumulating public capital and its associated public...

The main objective of this paper is to contribute to in-depth literature on the relationship between growth and the informal sector in the presence of corruption. The impact of the interaction between growth and corruption on economic performance (increase or decrease of the informal sector)...

The informal sector (IS) plays a significant role in developing countries viz. the provision of employment, income and supplying ignored markets. However, working and employment conditions within the sector are still poor. Its expansion and changing structures have thus drawn the attention of...

Two stylized representations are often found in the academic and policy literature on informality and formality in developing countries. The first is that the informal (or unregulated) sector is more competitive than the formal (or regulated) sector. The second is that contract enforcement is...

The main goal of this study is two-fold: (1) to provide a general overview of thecontributions to the literature on the informal sector, with a special focus on the PublicChoice approach; and (2) to compare these contributions across two institutionallydifferent types of countries: developed and...

A number of theoretical studies have tended to trace the nature of globalization process' impacts (mostly characterised by trade opening) on informality, while relevant empirical literature has been not well developed. The paper aims to fill this knowledge gap by shedding further light on the...
