Повний текст джерелаIn this thesis, we tried to know the relationship between the variability of exchange rates, trade flows and economic growth in Madagascar. In other words, we have studied the effects of volatility and misalignment of the exchange rate on exports, imports, and economic growth. To conduct this study, we used annual data from the 1971-2012 period for global exports and imports, and the 1990-2011 period for exports and imports by sector. We measured the volatility using two methods, and we got the volatility by moving standard deviation and volatility calculated by the GARCH. The method of cointegration was used to study the variables. With NATREX model, the misalignment was calculated as the difference between REER at time t and REER equilibrium. On the last part of this work and to resolve our problem, we use the method SUR (Seemingly Unrelated Regression). This method allowed us to estimate our model with two equations for export volumes and import volumes.Finally, the results show that for the case of Madagascar, considering exports, misalignment has a significant positive impact on overall export whatever the definition of volatility, indeed over-evaluation increases export. Then, volatility has a significant positive impact on overall export only with the inclusion of VOLGARCHTCEN. Moreover considering imports, misalignment has a significant positive impact on the overall import with the inclusion of VOLMASDTCER, and VOLMASDTCEN, over-evaluation increases import. The volatility has a significant positive impact on the import in the case of : VOLMASDTCEN, VOLGARCHTCER, VOLGARCHTCEN. With the global export or import, misalignment has no significant impact on the growth rate, however volatility has a significant negative impact on growth rates considering VOLMASDTCER, and VOLMASDTCEN

Повний текст джерелаRecognizing the importance of the exchange rate system for open economies, we study the macroeconomic effects of exchange rate regimes. In the first chapter, we define the exchange rate regime and discuss the official or de jure classification of exchange regimes by the International Monetary Fund (IMF) as well as de factoclassifications developed by Levy Yeyati and Sturzenegger (2005) and by Reinhart and Rogoff (2003). We subsequently discuss the question of which classification(s) of regimes to use. In the second chapter, the impact of exchange rate regimes on growth volatility is investigated. Building on the literature on the relationships between the exchange rate arrangement and volatility and the literature on the determinants of growth volatility, the objective is to know whether the exchange rate system affects growth volatility once the determinants of volatility identified by the existing literature are controlled for. The chapter also assesses the channels through which the exchange rate regime affects volatility. In particular, we ask whether the contribution of terms of trade instability to growth volatility is influenced by the exchange rate arrangement. Is the impact of the exchange rate regime on volatility affected by financial and economic development ? Volatility or instability is measured from a trend which process is obtained from panel unit root tests. By using de jure exchange rate regimes along with de facto ones as classified by Reinhart et Rogoff (2003), we are able to assess the sensitivity of the results to the classification of exchange regimes. In the third chapter, the analysis is taken a step further by investigating whether the relation between growth and volatility is modified by the exchange rate system. Does the exchange rate regime modify the direct impact of volatility on growth ? In other words, does a given level of volatility reduces output growth identically under fixed and flexible regimes ? Moreover, are the indirect effects of volatility on the growth rate of per capita real output modified by the exchange rate system ? To answer the latter question, the channels of investment, human capital, trade and financial development are considered. Another objective of the chapter is to verify whether the effects of exchange rate regimes and volatility on output growth are heterogeneous or not according to the very quantiles of output growth. To pursue this avenue, we use the technique of regression quantiles with instrumental variables. In the fourth chapter, the impact of the exchange rate arrangement on the economy's adjustment is analyzed. Does the adjustment of the economy – measured by real exchange rate misalignment – depend on the exchange rate regime ? Is the impact of the exchange rate system on misalignment explained by its effects on real overvaluation and undervaluation episodes ? What do de jure and de facto exchange rate regimes, and deviations of announced from observed exchange rate policies reveal ? To answer these questions, we follow two steps. In the first one, a cointegration relation between the real exchange rate and its real and nominal determinants is estimated using non stationary panel techniques (Pedroni, 1996, 2000 and 2004) in the samples of low income, middle income and high income countries. Misalignment is then obtained as the deviation of the actual real exchange rate from its equilibrium value, the latter being determined by the equilibrium values of the fundamentals. In the second step, the impact of the exchange rate regime on the economy's adjustment is assessed using the measure of real exchange rate misalignment computed in the first step

Повний текст джерелаThis thesis examines whether or not it is beneficial for least developed countries to engage more in the process of financial globalization in pursuit of their economic growth, and if this process influences the effects of financial and monetary instability on the latter. This thesis is divided into three parts. Before examining the theoretical framework of financial globalization, the first part sketches its genesis on a background of the research for an answer to the problem of its regulation. The second part focuses on the literature on the impact of financial globalization on growth. This is done in order to draw lessons for the establishment of a study covering 72 low-income developing countries over the period 1972-2011. The third part centers on the impact on economic growth of financial globalization and the two aforementioned types of instability, discussed both separately and in conjunction. Evidence is provided by two empirical studies based on the same spatio-temporal framework as the previous one. These studies are preceded by a review of the literature on the relationship between financial globalization, financial and then monetary instability and growth, in addition to a theoretical analysis of financial instability. This illustrates that financial and monetary instability have negative effects on growth, while financial globalization and in particular investment-globalization, unlike indebtedness-globalization, promotes the benefits of macroeconomic policies and international trade. This can be find in addition to its direct positive effect on growth, even in the presence of the two instabilities of which it reduces the negative effects

Повний текст джерелаThis dissertation presents new theoretical and empirical evidence on the properties of firms' and industry dynamics and international trade. In particular, this thesis aims at answering a series research questions linked to the explanation of firms' heterogeneity in the context of the most recent findings related to both firms' learning and imperfect selection.First, we provide a survey of the main mechanisms of market selection used in economics. We gather them in three theoretical paradigms, that we try to reconcile in terms of underlying laws of selection. We show that the three paradigms have been converging to selection mechanisms focussing on firm heterogeneity and increasing returns, that are however fostered by theories which differ in terms of sources of increasing returns, generating mechanisms of firm heterogeneity, firm rationality and emphasis on equilibrium states vis-á-vis out-of-equilibrium dynamics. Our discussion suggests that the convergence between the theoretical paradigms is taking place in the direction of research, which is aimed at the replication of empirical patterns related to firm heterogeneity, rather than in the theory underlying selection mechanisms.Second, we build a simple international trade two-country model of competition among heterogeneous firms to study the effects that firm learning and imperfect market selection exert on export flows, market shares and firm productivities. Market selection in each country is driven by a finite pairwise Pólya urn process, which embodies dynamic increasing returns at the firm level. In presence of a static distribution of firm productivity, the market selection process leads to a monopoly. When firm learning is included in the model, markets converge to non-monopolistic structures, whose degree of competition depends on trade openness and selection intensity. Finally, we show that our simple stochastic model with firm learning and imperfect selection is able to jointly reproduce a wide ensemble of stylized facts concerning intra-industry trade, industry and firm dynamics. In addition, we show that trade activities increase concentration and volatility.Third, we investigate the firm growth rates volatility-size relation and its determinants in a comprehensive dataset of French manufacturing firms between 1993 and 2009. Differently from previous contributions, we study the relation using sales data for firms at both the aggregate and sectoral level. First, we show that the relation deviates from the linear approximation found in previous studies. It is indeed J-shaped, very steep for small firms and flat for large ones. Second, we explain this new empirical finding via a tractable model of imperfect selection encompassing firms competing on the basis of both size and productivity. Our contribution suggests that large firms are Gibrat's and that the empirical shape of the firms' growth rates variance-size relation can be explained by imperfect selection mechanisms whose outcomes are mediated by both the strength of shares reallocation and firms' joint heterogeneity in size and productivity.Finally, we investigate the characteristics of firms using Artificial Intelligence (AI) and the link between AI use and productivity in a comprehensive database of French firms in 2018. We find that AI users tend to be larger and younger than non-users. AI use is positively related to several complementary assets, including digital infrastructure, complementary digital technologies, and human capital. Focussing on the AI-productivity nexus, we show that the largest AI users are more productive, but that this premium is related to their selection into AI use. When we consider either all AI users or AI buyers, no average relationship between AI and productivity growth could be retrieved. However, we find a positive AI-productivity link for AI developers, especially when productivity growth over a sufficiently long time period is considered

Повний текст джерелаThis PhD thesis is devoted to the study of an Affine Term Structure Model where we use Wishart-like processes to model the stochastic variance-covariance of interest rates. This work was initially motivated by some thoughts on calibration and model risk in hedging interest rates derivatives. The ambition of our work is to build a model which reduces as much as possible the noise coming from daily re-calibration of the model to the market. It is standard market practice to hedge interest rates derivatives using models with parameters that are calibrated on a daily basis to fit the market prices of a set of well chosen instruments (typically the instrument that will be used to hedge the derivative). The model assumes that the parameters are constant, and the model price is based on this assumption; however since these parameters are re-calibrated, they become in fact stochastic. Therefore, calibration introduces some additional terms in the price dynamics (precisely in the drift term of the dynamics) which can lead to poor P&L explain, and mishedging. The initial idea of our research work is to replace the parameters by factors, and assume a dynamics for these factors, and assume that all the parameters involved in the model are constant. Instead of calibrating the parameters to the market, we fit the value of the factors to the observed market prices. A large part of this work has been devoted to the development of an efficient numerical framework to implement the model. We study second order discretization schemes for Monte Carlo simulation of the model. We also study efficient methods for pricing vanilla instruments such as swaptions and caplets. In particular, we investigate expansion techniques for prices and volatility of caplets and swaptions. The arguments that we use to obtain the expansion rely on an expansion of the infinitesimal generator with respect to a perturbation factor. Finally we have studied the calibration problem. As mentioned before, the idea of the model we study in this thesis is to keep the parameters of the model constant, and calibrate the values of the factors to fit the market. In particular, we need to calibrate the initial values (or the variations) of the Wishart-like process to fit the market, which introduces a positive semidefinite constraint in the optimization problem. Semidefinite programming (SDP) gives a natural framework to handle this constraint

Повний текст джерелаThis thesis questions both conventional macroeconomic theory and economic policy doctrines about their ability to inform and address fiscal policy issues since the 2008 crisis. The introductory chapter proposes a descriptive analysis. After a long period of increasing public debt, budgetary deficits plunge during the recession, but interest rates continue to fall except in a few countries, whose governments were facing serious fiscal troubles. Inflation stabilizes at a low level, but interest rates turn negative. Potential growth continue to slowdown and the hypothesis of secular stagnation becomes plausible. The second chapter discusses the role of rating agencies and their real or perceived power. Rating agencies have been accused of increasing default risk by degrading the rating of troubled countries, causing interest rate hikes. We conduct an empirical study on the recent budgetary crisis that affected the GIIPS (Greece, Ireland, Italy, Portugal and Spain) within the euro area. The causal relationships between the ratings of the three main agencies (Moody’s, Standard and Poor’s and Fitch Ratings) and the five sovereign spreads are systematically tested. These tests suggest that it is rather the risk premium who causes a variation of the note, and not the opposite. The rating agency provides information that has already been anticipated by the financial markets. This result must be nuanced because a causal relationship of the warnings of degradation (outlook) is detected. The third chapter deals with the explanatory factors of real interest rates. The standard model (AS-AD) states that the equilibrium interest rate must increase following a fiscal expansion or as a result of a slowing of potential growth, regardless of the regime (classic, Keynesian or intermediate). Extensions of the model allow us to consider external influences, sovereign risk premiums, potential growth and expectations. This does not reverse the predictions of the model and the theory is reconciled with the facts only when the Keynesian hypothesis of propensity to consume is questioned. The introduction of intertemporal consumption behavior (permanent income) provides a plausible explanation for the combination of slow growth and low interest rates. We estimate an econometric relationship on annual data for a panel of 19 OECD countries. These tests confirm the influence of the factors suggested by the theoretical models, in particular the link between lowering interest rates and economic slowdown. The fourth chapter develops a reflection on the risk of sovereign default. Doubts about debt sustainability in some developed countries resurfaced after the 2008 crisis. Debt restructuring in the form of a conditional loan has emerged as a multilateral solution to fight the occurrence of defaults. Another way is to mutualize the debts of the governments of a same zone. We build a static model which can represent these three alternative notions (default, restructuring and mutualization). A situation is described in which two governments may decide to default or repay their debts. A calibrated numerical application on Greece’s default in 2012 allows us to categorize its defaults as strategic and to note that the restructuring has tipped its decision, making the repayment beneficial. The upstream existence of a Eurobond with a common interest rate of less than 3.5% would also have prevented the implementation of the Greek default and avoided an expensive debt restructuring

Повний текст джерелаLn this Thesis we study volatility issues across three broad economic fields, namely international trade, the banking sector, and monetary policy. They share the common feature of having the volatility of one variable to be a key ingredient of the econometric model. Indeed, in the second Chapter of this thesis, we study the impact of real exchange rate volatility on exports in Argentina since the 1980s. The empirics of this topic are discussed in view of the twofold dimension of trade relations: the impact of intra-regional (with Brazil) and extra regional (with the rest of the world) real exchange rate volatility, on both intra and extra-regional exports. In Chapter 3, we move to the issue of the impact of foreign bank presence on credit volatility, focusing in a panel of eight Latin American countries over the period 1995-2001. In the forth Chapter, instead of focusing on how volatility affects one variable, or how one variable may affect volatility, we look at the presence of volatility spillovers between interest rates and expected ination in Brazil, Chile, Colombia and Mexico, four countries that have implemented ination targeting regimes at the end of the 1990s. In Chapter 5, we study the long term dynamics of the Argentinean current count. Finally, we conclude with a summary of the main findings of this thesis we offer some venues for further research

Повний текст джерелаFaced with the success of Southeast Asian economies, fueled by an export-led growth strategy, an important literature developed around the question of the growth effects of exchange rate misalignments. This work provides further insights on this question, by focusing on the particular case of Sub-Saharan African countries, whose growth has picked up since the beginning of the 21st century. In this perspective, we first determine the equilibrium exchange rate as this value provides a benchmark for the computation of misalignments. This step allows us to tackle the importance of the exchange rate regime in limiting misalignments. It seems that the exchange rate regime has an ambiguous effect on limiting misalignments. Subsequent to this analysis, we assess the impact of misalignments on growth in 16 Sub-Saharan African countries. The results of this assessment are in favor of the thesis that the overvaluation acts negatively on growth. However, the under-valuation of the exchange rate does not have a positive effect, irrespective of the institutional framework considered. Therefore, it seems that countries' exit from the Franc Zone cannot be justified by the expectation that the manipulation of the exchange rate would offer countries more policy flexibility

Повний текст джерелаThis thesis attempts to shed new light on the link hotly debated and contested between exchange rates fluctuations and economic growth. We sought to report under various empirical exercises the impact of misalignments on economic growth in many developed, emerging and developing countries since the 1980s until the most recent period. The four empirical applications of this thesis and all intended to answer this question, but from different angles of view. Three main contributions come from our thesis. The first on is to identify the impact of exchange rate misalignments on economic growth, and its evolution accross time. We have shown that misalignments are harmful for growth throughout the following period (1980-2010) and the gradual reduction of their magnitude is accompanied by a reduction of their impact on economic growth in the major economies G7. The second contribution of this thesis lies in the search for a possible non-linearity in the misalignment-growth nexus. Using a threshold model, we have highlighted the existence of non-linearities in the relationship between misalignments and growth. The third contribution of this thesis lies in the analysis of the international transmission of currency misalignments on economic growth for both developed and emerging markets. Thus, using a GVAR model, we investigate the effects of overvaluation and undervaluation of the dollar, the euro and the renminbi on their own growth, but also that of their partners. The results highlight the leadership of the U.S. economy in global growth, but it also appears that the reduction of global imbalances is not linked to an adjustment of the dollar

We first peruse the Dutch disease transmission mechanism. Then, based on theoretical frameworks developed for equilibrium exchanges rate estimation and adapted to the needs of our work, and using cointegrated VAR modeling techniques associated with impulse response functions, we analyze inter-relations between real exchange rate, aid, growth, investment and other key variables for sixteen countries in West and Central Africa. The main finding of the study is that in general, aid does not cause Dutch disease in these countries

Повний текст джерелаThis study aims to evaluate, on the one hand, the role of the inflation differential in the exchange rate volatility and, on the other hand, the impact of this volatility in explaining inflation and in implementation of monetary policy in a small open economy such as Haiti, a net importing country with the United States as its main trading partner. To determine the impact of the inflation differential on the volatility of the exchange rate, we estimate a GARCH model. The results of the estimation of the variance equation showed that a 1% increase in the inflation differential between the two (2) countries causes a 0.02% increase in exchange rate volatility. In addition, the volatility of the exchange rate has a positive impact on inflation. Following the estimation of the determinants of inflation by a VAR (1) model, the impulse response function revealed that after a shock, the pass-through of the exchange rate on consumer prices is more than complete after six months with shock transmission at over 100%. The effect increases gradually to 110% after two quarters then to 165% and 184% in the third and fourth quarters. In the case of pass-through on imported inflation, a shock of the exchange rate give rise to 2.7% on imported prices after two quarters and 3.6% in the third quarter. These results suggest that, unexpectedly, a shock on import prices does not have an immediate and significant impact on inflation, since its impact is estimated at 33% in the second quarter. Moreover, after one quarter, the variance of the forecast error of inflation is due to its own innovations. And after two quarters, the contribution of each variable to the variance of the forecast error becomes more precise. In this sense, about 5.61% of the variance of the inflation error is explained by the volatility of the exchange rate, 3.84% by the growth of the money supply M2 and 0.51% and 0, 02% by the variation of the import prices and the interest rate respectively. Given the dominant role of the nominal exchange rate in explaining inflation, does the Bank of the Republic of Haiti take into account the exchange rate in the orientation of its monetary policy by following a Ball rule? The results confirm that the Bank of the Republic of Haiti, rather than a traditional Taylor rule, follows a Ball rule by modifying its key interest rate according to the variation of the exchange rate (0, 65%). Similarly, the Haitian monetary authorities adopt a smoothing behavior since the introduction of the delayed interest rate has a coefficient of 0.81, which is significant. The dominance of the interest rate and the exchange rate, in the evolution of inflation and in the implementation of monetary policy, justifies the relevance of calculating an indicator of monetary conditions (ICM) by combining the two aforementioned variables. Two models were estimated: an equation of aggregate demand and one of inflation. The calculated relative weights indicate a larger weight of the certain exchange rate (-0.08) on inflation compared to that of the nominal interest rate (-0.005). These coefficients were used to calculate the real and nominal monetary Conditions Index (MCI). The coefficient of correlation between the nominal MCI and inflation was greater (54.62%) compared to that between the real MCI and inflation (-8.1%). Indeed, after an increase of inflation, the monetary authorities are forced to harden the nominal monetary conditions

Повний текст джерелаThis thesis is part of the guideline of works seeking to discuss / explain the determinants of exchange rates in a flexible regime context. In particular, it focuses on examining the behavior of the Euro-US dollar exchange rate by referring in particular to fundamentals and order flows, in connection with monetarist and microstructural approaches. Two aspects of exchange rate behavior are explored: its dynamics and volatility. For these purposes, this study places particular emphasis on the fact that the new concept of order flow is a reliable approximation of unobservable and / or unquantifiable macroeconomic fundamentals. The results show that the initial depreciation of the Euro against the US Dollar stems mainly from a strong monetary expansion in Europe and a massive capital outflow to the United States. Moreover, this study shows that the instabilities of the empirically detected monetary models are the result of an inappropriate specification of the determinants of the exchange rate and that the level of stability of the long-term relationship goes hand in hand with the degree of disaggregation of the flows. order. As for the study of the macroeconomic determinants of exchange rate volatility, this thesis revisits, on a theoretical level, the GARCH-MIDAS approach of Engle, GhysEls and Sohn (2006,2013). Then, on an empirical level, this study compared the estimates and forecasts provided by the two approaches (classical and reinforced), where it highlighted the superiority, in terms of forecast quality, of GARCH-MIDAS augmented by a random walk

Повний текст джерелаThis dissertation contains three essays on different issues on mergers and acquisitions, left unexplored or unresolved by the existing literature. The first study examine the relationship between Islamic finance development and economic growth in a panel of 15 MENA and Sout-est-asia countries over the 2000-2009 period, using a variety of econometric methods and four standard measures of Islamic financial development. The study identifies two sets of findings. First, fixed effects estimation, panel-data-instrument variables regressions and GMM-difference estimator reveal that the relationship between Islamic financial development and economic growth is positive. The semiparametric panel model shows that there is evidence of nonlinearity in the data. The second study, assess empirically the effect of the 2007-2008 subprime financial crisis on Islamic banks using a sample of 27 Islamic banks and 43 conventional banks during the period from 2005 to 2009. Using the Z-score as indicator of bank stability the results of our regression analysis show that there is no difference in terms of the effect of the financial crisis on the soundness of Islamic bank and their conventional counterparts. The third study aims to examine the volatility of Islamic stock index compared to their conventional counterparts. Five major Islamic stock indexes have been the subject of our third study as well as their conventional counterparts. Covering a time period from 12/02/2009 to 12/02/2014. The application of Granger causality tests detected different causalities during the period, between the returns series under study. Employing Generalized Autoregressive Conditional Heteroskedastic (GARCH), our results indicate that, four among five Islamic stock indexes were less volatile than their conventional counterparts. But, one Islamic index are more volatile than their conventional counterpart

Повний текст джерелаThe purpose of this thesis is the analysis of the variability of the real effective exchange rate (REER) on foreign trade total and sectoral of Tunisia over the period 1975-2009. Variability REER means volatility and misalignment. Volatility is measured by the mobile standard deviation (ETM) and the GARCH (1, 1). However, the misalignment of REER is measured by the deviation from the equilibrium rate given by three theories of exchange rate equilibrium namely the Edwards model, BEER and NATREX. Using estimates of exports and imports models with / without breaks, the results showed that the effects of volatility on trade are not very relevant in the long term. But the effects of the exchange rate misalignment appear very relevant mainly when the sectoral trade flows are used

Повний текст джерелаNumerical simulation is today a usual practice for the design of industrial pieces and structures. In this context, the description of the damage of metals represents a new challenge. But damage models have to face a major difficulty: an abusive mesh dependency of the results which is called localization. In order to solve this problem, a damage model whose rate is limited, also called delayed damage model, was developed. Recent studies showed its aptitudes in dynamic to prevent localization. Its use in dynamic finite element codes implies however new problems to which an answer is proposed. An analytical expression of the size of the fully damaged zone, also called characteristic length, is given initially. This allows to evaluate a priori the adequate mesh size. Coupled to an original convergence analysis of the model, it should allow in the future to reduce considerably computation cost by using appropriate numerical techniques as remeshing, multi-grips methods or domain decomposition. For an industrial application, the length of the calculation remains too large. Furthermore, two ways of identification of the two delayed damage parameters using plates impact experiment are proposed. These two protocols are then applied successively for the first time to an aluminium alloy on the one hand and to an titanium ally on the other. Lastly, the implementation of the model was achieved in the fast dynamic finite element code Europlexus, some simulations are proposed. In the mean time, they allow the application and the validation of the various developments carried out previously

Повний текст джерелаTwo major facts hold place to explain the interest of the variability of Real exchange rate (RER) in emergent countries. First, the International Financial integration (IFI), corollary of the abandonment of Bretton-Woods's system, and the proliferation of floating exchange rate regimes, amplified partially fluctuations and disequilibria of RER, notably in emergent countries. Then, the frequent exchange rate fluctuations, called volatility of RER, and the recurrent distortion, called misalignment of RER, build generally a matrix of crises and lower economic performance. These considerations drove economists to reconsider the question of the variability of RER, its determinants and its induced effects on the economic growth in emergent countries. Also, this question occupies a crucial position in research articulating macroeconomic and international finance. Our thesis appears in such a perspective of research; it is a reflection on the characterization of the nature and the extent of the mediation between RER variability and economic growth in the context of International Financial Integration The empirical validation of such a characterization took support on a widened sample constituted of heterogeneous emergent countries, on the one hand, and on an intensive recourse to econometric tools, on the other one. In addition, it has been question of empiric estimation articulating relatively recent econometric techniques, as the GMM in dynamic panel, panel co-integration and the method of Dynamics of Least Squared (DOLS). To the term of this empirical effort, we are allowed to note that the RER variability is an explanatory element of the economic decrease in emergent countries, decrease amplified by the IFI that intensifies this variability

Повний текст джерелаBizerte lagoon, which supports intensive fishery activities and several aquaculture farms, is experiencing increasing anthropogenic pollutants loading from expanding urban, agricultural and industrial development along its shores. The focus of this thesis was to study the trophic structure and interactions within the planktonic food web in the lagoon, to assess the trophic status of the lagoon and the fate of biogenic carbon under different anthropogenic impacts. Four stations were investigated in summer 2004 (MA : impacted by urban discharge, MB : influenced by industrial activity, MJ : located in proximity of a shellfish farming sector, and R : in the lagoon central area). Station MJ was designed for a seasonal investigation. The sampling was carried out at three depths at each station for dissolved organic carbon (DOC), particulate organic carbon (POC), abundance, biomass and composition of phytoplankton, micro- and mesozooplankton. Dilution method was used to estimate growth of the three phytoplanktonic fractions and bacteria and their grazing by micrograzers. The sedimentation of carbon particles was also assessed (POC, phytoplankton, faecal pellets, and detrital matter). Primary and bacterial productions were determined in spring for MJ. Planktonic trophic food web of each station and season was modelled using the inverse method. The pattern of the estimated fluxes was characterized by network analysis

Повний текст джерелаThis thesis presents the results of a chemical and radiochemical study of numerous polymetallic nodules from the Peru basin (South Eastern Pacific) and associated sediments. Three types of formation processes have been uncovered, each with its own characteristic accretion rate yielding nodules of different chemical composition. The elements responsible for the formation of the nodules come from three sources: 1) iron from the sea water (hydrogenous); 2) nickel and copper from the oxidizing sea water-sediment interface through early diagenesis; 3) manganese from the reducing diagenesis within the first few centimeters of the sediment. The nature of the sedimentary environment is directly responsible for the relative contribution of the three sources to the formation of the nodules. Two key factors: sedimentation rate and the amount of organic materiel in the sediments, determine the development of sedimentary surface diagenesis and the growth of diagenetic nodules. Within the Peru basin, two distinct zones of nodules are recognizable : zone 1, starting 6° South, has nodules resulting from reducing diagenesis; zone 2, South of 9°S, contains a mixture of nodules formed by early diagenesis in an oxidizing environment and by water transport, in proportions determined by the bottom topography and water currents. The results have made it possible to define more precisely the chemical composition of the three components. The results have been compared with those published for North Pacific and they agree well. The lateral zones are symmetrical with respect to the equator, confirming thus the key role of the organic matter in the growth of nodules
