We explore the costs and benefits of informality associated with the informal sector lying outside the tax regime in a two-sector New Keynesian model. The informal sector is more labour intensive, has a lower labour productivity, is untaxed and has a classical labour market. The formal sector bears all the taxation costs, produces all the governmen...

How does informality in emerging economies affect the conduct of monetary policy? To answer this question we construct a two-sector, formal-informal new Keynesian closed-economy. The informal sector is more labour intensive, is untaxed, has a classical labour market, faces high credit constraints in financing investment and is less visible in terms...

How does informality in emerging economies affect the conduct of monetary and fiscal policy? To answer this question we construct a two-sector, formal-informal new Keynesian closed-economy. The informal sector is more labour intensive, is untaxed, has a classical labour market, faces high credit constraints in financing investment and is less visib...

Using a two-bloc endogenous growth model calibrated to two generic sending and receiving countries of equal size, we assess the growth and welfare impact of world migration flows of different skill compositions. The sending country (East) has a lower total factor productivity and a lower endowment of skilled labour. Migration can induce two growth-...

The UK, with its relatively liberal immigration policies following recent enlarge- ments, has been one of the main recipients of migrants from new EU member states. This paper poses the questions: what is the effect of immigration on a receiving econ- omy such as the UK? Is the effect beneficial or adverse for growth? Does emigration have brain dra...

The safety of patients is an important responsibility of health care providers, and significant compensation costs may arise if providers are negligent. A widely debated option involves liability for such compensation being placed with the hospital rather than the individual clinician, a system known as “enterprise liability.” In the United States,...

This paper reviews the literature on the informal economy, focusing first on empirical findings and then on existing approaches to modeling informality within both partial and general equilibrium environments. We concentrate on labour and credit markets, since these tend to be most affected by informality. The phenomenon is particularly important i...

The UK, with its relatively liberal immigration policies following recent enlargements, has been one of the main recipients of migrants from new EU member states. This paper poses the questions: what is the effect of immigration on a receiving economy such as the UK? Is the effect beneficial or adverse for growth? How differently would skilled (or...

We revisit the influential work of Borjas (1995) on the economic gain to the host population from immigration-"the immigration surplus." We develop his analysis by using a general equilibrium endogenous growth model with endogenous capital and several sectors, including an R&D sector driving growth. Skilled immigration leads to a bigger R&D sector...

Using a calibrated two-bloc endogenous growth model of the European economy, we assess the growth and welfare impact of East-West European migration of different skill compositions. The East has a lower total factor productivity and a lower endowment of skilled labour. Migration can induce two growth-enhancing effects: an efficiency effect from the...

This paper investigates the impact of international migration on technical efficiency, resource allocation and income from agricultural production of family farming in Albania. The results suggest that migration is used by rural households as a pathway out of agriculture: migration is negatively associated with both labour and non-labour input allo...

p> In this thesis we study the determinants and the economic effects of labour mobility in economic environments characterised by trading frictions, entry costs and credit constraints. People move to a different sector, or to a different geographical area, to improve their socioeconomic conditions. The focus is on the impact of mobility on inequali...

This survey reviews both theoretical and empirical papers that examine the economic effects of labour mobility with a particular reference to intra-European migration. We address three broad sets of issues: Firstly, the effect that immigration has on the host country's labour market. Although the possible adverse effects that immigration can have o...

Abstract This paper explores the costs and benefits of informalization of the economy in a New Keynesian two-sector closed economy. The informal sector is more labour intensive, is untaxed and has a classical labour market. We consider the case where it is also a ‘hidden’ unobserved sector. The more capital intensive formal sector bears all the tax...
