What happens when a previously uncovered labour market is regulated? We exploit the introduction of a minimum wage in South Africa and variation in the intensity of this law to identify increases in wages for domestic workers and find no statistically significant effects on the intensive or...

This paper presents theory and evidence on the determinants of the size of the informal sector. We propose a simple theoretical model in which it is positively related to income inequality, more so under weak institutions, and is negatively related to the economy's wealth. These predictions are...

In middle-income countries, the informal sector often accounts for a substantial fraction of urban employment. We develop a general equilibrium model with matching frictions in the urban labour market, the possibility of self-employment in the informal sector, and scope for rural-urban...

A stylized prediction of the development economics discourse is that informality will disappear with development. And yet in the last twenty years conventional measures of informality, far from declining, have either remained stagnant or have actually increased. What exactly is informality and...

This Paper studies the relationship between trade liberalization and informality. It is often claimed that increased foreign competition in developing countries leads to an expansion of the informal sector, defined as the sector that does not comply with labour market legislation. Using data...

This paper investigates how enforcement of labour regulation affects the firm's use of informal labour, firm size and firm performance. Using firm level data on employment, capita, and output, census data on informal employment at the city level, and administrative data on enforcement of...

A firm's productivity depends on how production is organized given the level of demand for its product. To capture this mechanism, we develop a theory of an economy where firms with heterogeneous demands use labor and knowledge to produce. Entrepreneurs decide the number of layers of management...

Many new exporters give up exporting very shortly, despite substantial entry costs; others shoot up foreign sales and expand to new destinations. We develop a model based on experimentation to rationalize these and other dynamic patterns of exporting firms. We posit that individual export...

This paper empirically tests the link between trade openness and enterprise restructuring in Bulgaria. It belongs to a recent line of work in the empirical trade literature that investigates the effects of trade policy on firm behaviour. The trade liberalization following the 1991 economic...

We examine interaction between goods trade and market power in domestic trade and distribution sectors. Theory suggests a linkage between service-sector competition and goods trade, one supported by econometrics involving imports of 22 OECD countries vis-à-vis 69 exporters. This points to...
