This paper explores the association between the informal economy and the adoption of central bank digital currency (CBDC) by end users, namely households and businesses. Our findings suggest that CBDC may not be widely accepted by end users in the presence of a sizable informal economy in which cash is the primary method of payment. CBDC can decrease informality, but this effect becomes weaker in countries with larger informal economies. Tax reduction and CBDC interest rates can be useful tools to promote the adoption and effectiveness of CBDC, leading to a reallocation effect between formal and informal sectors.

This paper examines the absorption of foreign aid in the presence of formal and informal production. Calibrating a two‐sector open economy model to 67 aid‐recipient countries for 1990–2019, we show that an increase in foreign aid drives resources into the informal sector, and away from the formal sector. With untied aid, the expansion of the informal sector can lead to an economic contraction through the Dutch Disease effect. An economic expansion with an increase in the share of formal production can be attained by re‐allocating existing aid to public investment rather than an increase in the aggregate level of aid.

The standard view suggests that removing barriers to entry and improving judicial enforcement reduces informality and boosts investment and growth. However, a general equilibrium approach shows that this conclusion may hold to a lesser extent in countries with a constrained supply of funds because of, for example, a more concentrated banking sector or lower financial openness. When the formal sector grows larger in those countries, more entrepreneurs become creditworthy, but the higher pressure on the credit market limits further capital accumulation. We show empirical evidence consistent with these predictions. ( JEL O16, O43, E26) [ABSTRACT FROM AUTHOR]

Controlling for a more comprehensive set of economic structure variables and using system generalized method of moment ( GMM) dynamic panel estimation, we consider the determinants of seigniorage. While we confirm some results found in previous literature, including an inverse relationship of financial development and exchange rate management to seigniorage, we find little evidence that political instability and polarization lead to greater reliance on seigniorage. We also find robust evidence that the size of the shadow economy and natural resource rents are directly related to seigniorage, the latter result likely a result of exchange rate management. Thus, an effective strategy to reduce reliance on seigniorage is to lower the incentives to operate in the shadow economy, while exchange rate management may be counter-productive in countries with considerable natural resource rents.

This study examines whether informal sector jobs are a source of training for young less-educated workers. Controlling for worker and job characteristics, it is found that, in the early years of workers' careers in Mexico, wage growth in the informal sector is higher than in the formal sector. This result is consistent with general human capital investment on-the-job if the informal labor market is more competitive than the formal labor market due to frictions generated by labor regulations.
