Повний текст джерелаThis thesis contributes to the literature on the impact of weather shocks on migration and food security in Sub-Saharan Africa. The first chapter analyses whether Tanzanian rural households engage in internal migration as a response to weather-related shocks using an iv probit model. The findings confirm that for an average household, a 1 per cent reduction in agricultural income induced by weather shock increases the probability of migration by 13 percentage points on average within the following year. The second chapter paper attempts to establish if weather acts as the determinant of destination choice in the case of rural-to-rural migration. Employing the alternative-specific conditional logit model, this paper shows that an increase in the expected income differentials between origin and destination by 10,000 Tanzanian shillings, attributable to differences in weather, increases the probability of choosing a given destination by 2 percentage points. The third chapter analyses the food access dimension of food security, and models the link between weather shocks and food security that acts specifically through food prices. Employing an instrumental variable model where household dietary diversity is determined by food prices instrumented with weather shock, this chapter shows that a 1 per cent increase in local food prices induced by a weather shock decreases the number of food items consumed by households by around 2.5 per cent
Bourgeon, Pauline. "Essays on the impact of shocks on international flows and productivity." Thesis, Paris 1, 2017. http://www.theses.fr/2017PA01E023.
Повний текст джерелаThis thesis covers various issues in international economics and macroeconomics.It studies the role of several types of shocks on international migration, firms’ export strategies and sectoral productivity growth. The three chapters exploit different sources of data and use recent econometrics approaches to deal with these issues.Chapter one contributes to the literature on international migration by looking at the role of short-run fluctuations as determinants of the location choice of the migrants. We find evidence that business cycles and employment rates at destination affect the intensity of gross bilateral flows.Chapter two investigates how financial frictions impact firms’ foreign sales, especially for firms that export to long distance export markets. We find that firmsfacing financial frictions export from 4 to 10% less than the ones without anyfinancial constraints. Our results also suggest that amongst exporters facing financial difficulties, those who export to faraway destinations reduce their exportsales more.Chapter three investigates how financial frictions affect the efficiency with which labor allocates across firms within a sector. Results suggest that an increase intangibility decreases the productivity growth rate of an industry located in highly financially developed country and this lower productivity growth rate is largely explained by the reallocation of labour across firms within the sector
Safir, Abla. "The Impact of Income Shocks on Migration in Developing Countries." Paris, EHESS, 2009. http://www.theses.fr/2009EHES0057.
Повний текст джерелаThis dissertation examines the impact of income shocks on migration. Chapter 2 uses fixed-effect and instrumental variable estimates to measure the impact of farm income shocks on temporary migration of rural households in India. Chapter 3 examines migration throughout the period spanning 1993-2000 to understand migration decisions before and after the Indonesian 1997/1998 financial crisis. In chapter 4, I examine the impact of income shocks in 2004 or 2005 as mentioned by the interviewed households on migration m 2005 or 2006 and on transfers in 2006. Temporary migration in rural households in India and permanent migration in Senegal seem to be coping mechanisms in a classic model of labor migration, with an increase in departures in reponse to negative shocks. In India, a small positive impact of positive idiosyncratic shocks hints towards response to negative shocks. In India, a small positive impact of positive idiosyncratic shocks hints towards possible limitation of migration due to liquidity constraints. However, these constraints seem very weak when compared with the impact of the aggregate shock of low rainfall which increases migration. In Senegal, we also find some hints towards a larger understanding of migration as a means to manage shocks, with dependents joining households who have experiences positive shocks. In Indonesia however, we do not find that migration has increased in the case of individuals particularly affected by the crisis. The pervasive nature of the shock, even though it was heterogeneous, may have made individuals less willing to take risks through migration

Adopting new technology need learning, either in the form of knowledge or by working with the adopted technology. While the role of learning in the decision to adopt is widely investigated in the literature, its role in knowing how to best use technology and the speed of learning is not. In the first chapter, we investigate the adoption of the use of groundwater technology. When farmers adopt groundwater extraction technology, they need to learn about how to best use the technology to maximize their profit in the short and long run. We use five sets of data from Iran to show the existence of learning in the use of groundwater technology. Our findings improve the discussion on the regulation of firms in using common resources. This paper also provides new insights for optimizing climate change scenarios, in light of the importance of the learning lag in using new technologies. In chapter two, we discuss the effects of precipitation shocks on the rural labor market and migration. Weather shocks affect the welfare of workers in rural areas. This paper examines the impact of precipitation shocks on labor supply and out-migration in rural Iran. We use individual-level and station-based precipitation data at the rural-agglomeration level to study the effects of precipitation shocks on employment. Our results indicate different types of responses to positive and negative shocks. We find that workers in agriculture and industry sectors increase their hours of work in response to positive shocks and negative shocks reduce the labor market participation of women. We also show that the labor market is a channel through which precipitation shocks affect migratory decisions. In the final chapter, we investigate parents' investment in the quality of their children. While school enrollment at the primary level has been rising in developing countries, international measures of education quality, especially in basic knowledge of reading and math, do not exhibit a parallel improvement. Since parents' expenditure is an important determinant of children's school performance, we investigate parents' investments in the quality of their children's education, measured by their spending on books and other school materials. We develop a model, in which we consider families' expenditure as an input to their children's human capital. We hypothesize that families consider better school performance to be a reliable predictor of future return. Empirically, we test our hypothesis, and it is accepted using data for Ghanaian primary school students in rural areas.

Повний текст джерелаThe three essays composing this thesis make contributions to the literature on the consequences of migration and private transfers on the economic development of the countries of origin of sub-Saharan Africa.The first essay evaluates the distributive impact of international and domestic transfersin Senegal. The results show that private transfers reduce income inequality in Senegal. This equalizing effect is mainly driven bydomestic transfers. The second essay examines the insurance function of migration in Mali. We find that migration acts as an insurance mechanism when the household suffers an idiosyncratic shock during the year. The third essay examines the link between the human capital of Senegalese migrants and their integration into the destination labor market. The results suggest that the probability of being in skilled employment given the level of education is lower in migration compared to Senegal. Although a priori distinct, the three essays have in common an approach that mobilizes household surveys and various microeconometric techniques to deal with the complexity of migration in order to improve the understanding of the consequences of migration on the economies of origines

Повний текст джерелаThis PhD research proposes to study the relationship between informal risk-coping strategies and the nature of land allocation. Informal risk-coping mechanisms are studied here as one potential factor in the failure of land market reforms and the persistence of `non-market' exchange -gifts or free loans. In particular, we show that the bipolar view of land tenure, which opposes `customary' to `market' transfers, does not adequately approach informal risk-coping motivations in land transfers. Two hypotheses are analysed: first, in the absence of insurance markets and public social protection, land has a `safety net' function and households do not sell land but prefer other types of transfers (which retain part of the land's `safety net' function). Secondly, informal risk-coping leads households to participate to hybrid forms of transfers (neither market nor non-market) allowing to combine risk-coping motives with other types of economic necessities. Those two hypotheses are then looked at empirically in two case studies: in Vietnam, where households sell their land only if they are economically stable or have suffered income shocks (distress sales); and in Thailand, where a survey has been done among permanent rural-urban migrants. This surveyconfirms that informal risk-coping slows down land sale markets and sustains transfers such as free-loans. Finally, the Thai data identify traditional risk-sharing institutions in the allocation of land, especially through intra-family free-loans or `disguised rentals'. As a main conclusion, insurance and public protection policies could have a key role in the evaluation of land allocation systems in Thailand and Vietnam

Abstract Hepatocyte growth factor (HGF) and its receptor c-Met were frequently deregulated in hepatocellular carcinoma (HCC). Signaling pathways activated by HGF-c-Met are promising targets for preventing HCC progression. HGF can induce the reactive oxygen species (ROS) signaling for cell adhesion, migration and invasion of tumors including HCC. On the other hand, extracellular signal-regulated kinases (ERK), member of mitogen activated kinase, can be activated by ROS for a lot of cellular processes. As expected, HGF-induced phosphorylation of ERK and progression of HCC cell HepG2 were suppressed by ROS scavengers. By N-(biotinoyl)- N′-(iodoacetyl)-ethylenediamine (BIAM) labeling method, a lot of cysteine (-SH)- containing proteins with M.W. 50–75 kD were decreased in HepG2 treated with HGF or two other ROS generators, 12-O-tetradecanoyl-phorbol-13-acetate (TPA) and phenazine methosulfate(PMS). These redox sensitive proteins were identified by matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry. Among them, two chaperones, heat shock protein 60 (HSP60) and protein disulfide isomerase (PDI), were found to be the most common redox sensitive proteins in responding to all three agonists. Affinity blot of BIAM-labeled, immunoprecipitated HSP60 and PDI verified that HGF can decrease the cysteine (-SH) containing HSP60 and PDI. On the other hand, HGF and TPA increased cysteinyl glutathione-containing HSP60, consistent with the decrease of cysteine (-SH)-containing HSP60. Moreover, depletion of HSP60 and PDI or expression of dominant negative mutant of HSP60 with alteration of Cys, effectively prevented HGF-induced ERK phosphorylation and HepG2 migration. In conclusion, the redox sensitive HSP60 and PDI are required for HGF-induced ROS signaling and potential targets for preventing HCC progressions. Keywords: Hepatocyte growth factor; hepatocellular carcinoma; reactive oxygen species; extracellular signal-regulated kinases; heat shock protein 60; protein disulfide isomerase.

SALVATORE, VALENTINO. "Strombolian explosions: relationships between the conduit system and the resulting explosive activity at the vents." Doctoral thesis, 2019. http://hdl.handle.net/11573/1231295.
Повний текст джерелаPersistent, open-vent volcanoes frequently host Strombolian explosions. This style of activity is characterized by frequent (intervals of seconds to minutes) and impulsive (seconds- long) releases of pyroclasts and gases, due to the rise and burst of large gas bubbles (i.e., slugs) near the surface of the magma column. Over time, such volcanoes can show continuous changes in the evolution and migration of their active vents, from which also a highly variable behavior of the activity can be observed. The sources of such variability need being investigated at variable spatial and temporal scales. On a scale of years/hundred of meters, direct observation of space-time vent migration at multi-vent volcanoes is still limited, and the relationship between this variable activity and the shallow conduit system remains to be understood. On a scale of seconds/meters, many authors are focused on the dynamics of gas release and modes of pyroclasts formation, so far largely neglecting the ascent dynamics of pyroclasts from their release depth, where slugs burst, to their ejection from the vent. The aim of my study is the definition of the relationships between the physical parameters inside the volcanic conduit and their influence on the modes of pyroclast ejection in Strombolian explosions, accounting for the two scales abovementioned. To achieve this aim, I considered two separate yet complementary methodologies. The first one requires the characterization of Strombolian eruptions in nature investigating temporal changes in vent position at the crater terrace of Stromboli and explosion parameters (jet duration and geometry) using infrared surveillance camera videos collected between 2005 and 2009. Results by this first methodology provide a detailed database of normal Strombolian activity at different time-scales, as well as allowing one to outline a hierarchy of depths at which the shallow conduit system controls the explosive activity within the three main vent areas (i.e., south-west, central, and north-east) at Stromboli. At the shallowest depth, where slugs burst, vent shape and slug size control local explosion parameters, while shallower conduit branching determines the evolution of simultaneous or alternating twin vents. Below the depth of the slug burst, the conduit system feeding each vent area controls which specific vent will host the explosions and also some more general explosion features within a vent area. A link between the central and south-west vent areas is supposed at this depth, as supported by several observations. At the deepest level, the conduit system is common to all vent areas and sets the overall explosion rate of the volcano, balancing it between the north-east and the joint south-west and central vent areas. This kind of analysis may be performed also in other persistent multi-vent systems worldwide, providing basic inferences on geometry and dynamics of their conduit systems and on the hazard assessment. The second methodology is addressed on gas-particle jet simulations by means of scaled analogue experiments using a transparent shock-tube. This approach focuses on the effect of the initial source conditions (i.e., gas pressure and volume, sample position, size and amount of particles, vent geometry) both on the acceleration of the particles within the conduit and on the resulting ejection from the vent. Results show that maximum particle velocity has a strong positive correlation with initial energy and a weaker, negative correlation with both sample depth from the vent and particle size. Moreover, the experiments show trends of particle acceleration-deceleration in the shock-tube that variably depend on some initial conditions (i.e., initial energy, sample depth, and particle size) and influence particle maximum velocity recorded at the exit. When compared to processes occurring during low-scale explosive eruptions, these results open the way for potential, new inferences on the processes controlling the dynamics of pyroclasts. The acceleration-deceleration trends inside the conduits impact current models relating pyroclast ejection velocity with their source depth in the volcanic conduit. I show that, for a lower initial energy and a deeper sample, the model assumptions do not hold true anymore. Therefore, a model revision taking into account these trends is necessary before applying it to real eruptions. These results open the way to numerous future scenarios. Further experiments may, for instance, clarify, the effects of particle-gas coupling, analyze the role of other source parameters on pyroclast ejection (e.g., conduit diameter) and study other aspects (e.g., the volcanic plumes using very fine particles, or particle-particle and particle-wall collisions in the conduit).
