Resumo O objetivo deste artigo é analisar a dinâmica das migrações internacionais sul-sul a partir do estudo de caso da recente imigração de zimbabweanos para a província de Tete, Moçambique, historicamente uma região de emigração. Nesse sentido, examinamos as características sociodemográficas desses novos imigrantes, assim como as condições e motivações individuais, familiares e estruturais subjacentes ao fluxo migratório. Para tanto, combinamos dados quantitativos provenientes do Censo moçambicano de 2007 e dos registros de trabalhadores imigrantes da Direção Provincial de Trabalho, Emprego e Segurança Social, com entrevistas semiestruturadas junto aos imigrantes zimbabweanos em Tete. Os resultados indicam uma multiplicidade de fatores que contribuíram para a recente onda de imigração em Tete, com destaque, além das motivações econômicas e de subsistência familiares, para aspectos sociais e culturais relacionados à longa tradição da mobilidade intrarregional na África Austral, facilitada por fronteiras relativamente porosas e fortes laços culturais, linguísticos e de parentesco. Discutimos, também, como a instalação de megaprojetos de mineração com capital brasileiro, em Tete, contribuiu para torná-la atrativa como destino migratório, num contexto em que se assistiam violentas ondas de xenofobia contra imigrantes na África do Sul, principal destino das migrações na região. Abstract This article analyses the dynamics of international South-South migration through the case study of the recent immigration of Zimbabweans to the province of Tete, Mozambique, historically a region of emigration. We examine immigrants’ socio-demographic characteristics, as well as the individual, family and structural conditions and motivations underlying this new migration flow. The analysis combines quantitative data from the 2007 Mozambican Census and administrative records for immigrant workers from the Provincial Directorate of Labour, Employment and Social Security, with semi-structured interviews with Zimbabwean immigrants in Tete. The results indicate a multiplicity of factors that contributed to the recent wave of immigration in Tete. In addition to economic and subsistence motivations, social and cultural aspects related to the long tradition of intra-regional mobility in Southern Africa, facilitated by relatively porous borders and strong cultural, linguistic and kinship ties, seem to be important. We also discussed how the installation of mining megaprojects with Brazilian capital in Tete, contributed to its appeal as a migrant destination, in a context in which violent waves of xenophobia against immigrants were occurring in South Africa, the main destination for migrants in the region. Resumen El objetivo de este artículo es analizar la dinámica de la migración internacional sur-sur a partir del estudio de caso de la reciente inmigración de zimbabuenses a la provincia de Tete, Mozambique, históricamente una región de emigración. En este sentido, examinamos las características sociodemográficas de estos nuevos inmigrantes, así como las condiciones y motivaciones individuales, familiares y estructurales inherentes a este flujo migratorio. Para este fin, combinamos datos cuantitativos del censo de Mozambique de 2007 y registros de trabajadores inmigrantes de la Dirección Provincial de Trabajo, Empleo y Seguridad Social, con entrevistas semiestructuradas con inmigrantes zimbabuenses en Tete. Los resultados indican una multiplicidad de factores que contribuyeron a la reciente ola de inmigración en Tete, entre los que se destacan, además de las motivaciones económicas y de subsistencia familiar, aspectos sociales y culturales relacionados con la larga tradición de movilidad intrarregional en el sur de África, facilitada por fronteras relativamente porosas y por fuertes lazos culturales, lingüísticos y de parentesco. También discutimos cómo la instalación de megaproyectos mineros con capital brasileño en Tete contribuyó con su atractivo como destino migratorio, en un contexto en el que se asistía a violentas oleadas de xenofobia contra inmigrantes en Sudáfrica, el principal destino de las migraciones en la región.

"Over four million Colombians (around 10% of Colombia’s population) reside abroad and the UK is their second most favoured destination in Europe. Approximately 150,000 Colombians live and work in London and the UK is the fourth biggest source of remittances to Colombia. In recent years, the Colombian Government has toed the line of the migration-fordevelopment discourse emanating from the international development and aid agencies and has introduced policies to make their citizens abroad an integral part of a reconstituted definition of the Colombian nation. Under the umbrella of the ‘ColombiaNosUne’ programme, the government has sought to channel remittances towards mortgage-financed housing by promoting the "Mi casa con Remesas" programme and property fairs for Colombian migrants in their main cities of destination in the global north. Based on empirical data collected at both ends of the migration network, London and the Coffee Region of Colombia, this paper argues that the Colombian government’s conception of migrants as agents of development -and hence as financial subjects abroad- is tightly linked to wider attempts at the institutionalisation of migrants' practices in the transnational social field. These attempts are embedded in ideologically-driven neoliberal discourses of citizenship that privilege the financial market as the medium for individuals' and households' socioeconomic reproduction. Furthermore, they displace the responsibility for economic development from the state to its citizens and bring to the fore investment as the preferred mechanism for the "proper" use of remittances and through which migrant households’ connection to broader circuits of capital and finance can be exploited. Yet, although housing is a growing component of remittances expenditure, for the most part, Colombians in London are not embracing their newly-assigned financial subjectivities but are instead using alternative channels for housing acquisition and financing."

The study of the income velocity of money is important since monetary factors play a causal role in output fluctuations. The issue of the stability of money demand is critical in assessing the monetary aggregates, M1/M3, usefulness for the formulation of monetary policy. In Colombia, the M1 income velocity of money has been very volatile whereas the M3 velocity has been pretty stable over the last 20 years. Contrary to the assumption underlying the Quantity Theory of Money, the evidence here indicates that the income velocity of money is not constant in Colombia for the 1982 – 2001 period. The statistical results show that there is a positive relationship between the Colombian inflation rate and the M1 and M3 income velocities of money. A higher rate of inflation will translate into a higher nominal interest rate. The higher the interest rates the higher the opportunity cost of holding money and so the greater the income velocity.
