This paper considers optimal investment behaviour when investment options evolve deterministically or stochastically over time and investments are irreversible and indivisible. It extends the standard investment-under-uncertainty set-up with a single investment option to the case of repeated...

This paper considers off-farm labour activities by agricultural households in Nicaragua. It compares the role of: i) comparative advantages of households and individuals; and ii) agricultural conditions and market imperfections, in shaping off-farm labour supply. An econometric specification is...

We consider the economic implications of a compressed wage structure which is exogenously determined by institutions. An important feature of our analysis is that human capital is endogenous and can be achieved either as formal education or as informal training within firms after entering the...

While most countries welcome (and some even subsidise) high-skilled immigrants, there is very limited evidence of their importance for domestic firms. To guide our empirical analysis, we first set up a simple theoretical model to show how foreign experts may impact on the productivity and wages...

Many developed countries have recently experienced a significant inflow of immigrants in the agricultural sector. At the same time, the sector is still in a process of structural transformation resulting in fewer but bigger and presumably more efficient farms. In this paper, we exploit detailed...

In this paper, we propose and test a novel effect of immigration on the wages of native workers. Existing studies have focused on the wage effects that result from changes in the aggregate labour supply in a competitive labour market. We argue that if labour markets are not fully competitive,...

In this paper, we focus on the short-run adjustments taking place at the workplace level when immigrants are employed. Specifically, we analyse whether individual native workers are replaced or displaced by the employment of immigrants within the same narrowly defined occupations at the...

In this paper, we re-examine the role of economic self-interest in shaping people's attitudes towards immigration, using data from the European Social Survey 2002/2003. Compared to the existing literature, there are two main contributions of the present paper. First, we develop a more powerful...
