Alianza del pacífico; análisis de la contribución de los acuerdos en el sector agropecuario y el subsector agrícola en Colombia

Colombia es un país que ha logrado atraer la atención de diferentes países a nivel mundial debido al comportamiento económico que ha presentado en los últimos años. Gracias a estos resultados, es reconocida como mercado emergente debido a su rápido crecimiento interno en temas comerciales e industriales, y a sus notables y crecientes relaciones con otros países, entre otras características. En América Latina nos encontramos con varios países con características e iniciativas comerciales similares a las nuestras; países como Perú, Chile y México cuentan con infraestructuras de mercado de tamaño significativo y gran potencial, además de la cercanía geográfica (a excepción de México) y una gran similitud entre sus culturas, en 2011 surgió una iniciativa de integración regional para desarrollar progresivamente una libre circulación económica, de bienes, servicios, y personas. Con miras a convertirse en una plataforma política, económica y comercial a nivel mundial, enfocándose en la región Asia-Pacífico. Esta iniciativa se conoce como Alianza del Pacífico (AP) Uno de los subsectores más sensibles para los países miembros de la AP es el subsector agrícola. Debido a la baja diferenciación de productos y a la amenaza progresiva de un ingreso masivo de productos extranjeros a menor precio, pudiendo esto conseguir desestabilizar el mercado y afectando la producción interna o de los demás socios comerciales.

El papel de los principios en las fallas de los regímenes internacionales: el Fondo Monetario Internacional en la crisis económica argentina de 2001

Este trabajo de grado busca analizar el papel que juegan los principios en las fallas del Régimen Internacional de Pagos a la hora de responder a situaciones de crisis, específicamente, en la actuación del Fondo Monetario Internacional durante la crisis económica argentina de 2001. El Régimen, atado al cumplimiento de sus principios, actuó de manera tal que produjo unas fallas que terminaron exacerbando la crisis. Mediante el análisis de fuentes primarias y secundarias, y con métodos tanto cualitativos como cuantitativos se busca demostrar que efectivamente, los principios en los que se fundamentan las actuaciones de los regímenes, que son creencias, tienden a tornarse dogmáticos, por lo tanto, se hacen resistentes al cambio y no permiten a las instituciones obrar de manera que se ajuste a la realidad. Es así que los principios llegan agravar las crisis que debían solucionar, tal y como sucedió en Argentina en 2001.

Efectos de las reformas del fondo monetario internacional en la conformación de movimientos alterglobalización en el ecuador. Caso de análisis: movimiento de unidad plurinacional Pachakutik

El objetivo de la presente monografía de grado es explicar cómo las reformas del FMI implementadas en el Ecuador desde 1984 generaron una reestructuración de la economía que permitió la articulación organizativa e ideológica del Movimiento de Unidad Plurinacional Pachakutik (MUPP). Se analiza y explica el impacto de las reformas del FMI en la organización del MUPP y su accionar político en el Ecuador, desde la perspectiva de la teoría del neogramscianismo de Robert Cox, para entender el papel que las primeras tuvieron en la conformación y configuración del segundo. Se efectúa una revisión de textos académicos y programáticos del MUPP, entrevistas realizadas por terceros a los dirigentes del movimiento así como entrevistas realizadas por la autora.

Network externalities across financial institutions

We propose and estimate a financial distress model that explicitly accounts for the interactions or spill-over effects between financial institutions, through the use of a spatial continuity matrix that is build from financial network data of inter bank transactions. Such setup of the financial distress model allows for the empirical validation of the importance of network externalities in determining financial distress, in addition to institution specific and macroeconomic covariates. The relevance of such specification is that it incorporates simultaneously micro-prudential factors (Basel 2) as well as macro-prudential and systemic factors (Basel 3) as determinants of financial distress. Results indicate network externalities are an important determinant of financial health of a financial institutions. The parameter that measures the effect of network externalities is both economically and statistical significant and its inclusion as a risk factor reduces the importance of the firm specific variables such as the size or degree of leverage of the financial institution. In addition we analyze the policy implications of the network factor model for capital requirements and deposit insurance pricing.

Economic shocks and crime: evidence from the crash of ponzi schemes

In November 2008, Colombian authorities dismantled a network of Ponzi schemes, making hundreds of thousands of investors lose tens of millions of dollars throughout the country. Using original data on the geographical incidence of the Ponzi schemes, this paper estimates the impact of their break down on crime. We find that the crash of Ponzi schemes differentially exacerbated crime in affected districts. Confirming the intuition of the standard economic model of crime, this effect is only present in places with relatively weak judicial and law enforcement institutions, and with little access to consumption smoothing mechanisms such as microcredit. In addition, we show that, with the exception of economically-motivated felonies such as robbery, violent crime is not affected by the negative shock.

Desarrollo de un Modelo de Gestión de Riesgo de Crédito para instituciones de microfinanzas del Ecuador

La cartera vencida en el segmento de microcrédito evidenció una tendencia creciente desde el año 2011 hasta la actualidad. Cabe señalar que factores internos y externos han contribuido en el crecimiento de dicha cartera. Adicionalmente, el crecimiento de la cartera vencida tendrá una importante afectación en la IMF en los próximos años de mantenerse dicha tendencia creciente. Esta afectación se evidenciará en el crecimiento de las provisiones y el deterioro de los indicadores de liquidez y solvencia. El alcance del presente estudio comprende la estructuración del modelo de gestión de riesgo de crédito para instituciones de microfinanzas, el cual se basa en la adopción de técnicas estadísticas discriminantes en el proceso de concesión de microcréditos. La hipótesis señala que el modelo de gestión de riesgo de crédito para IMF, el cual comprende la estructuración del scoring de crédito de comportamiento como herramienta que segmenta el mercado objetivo; la adopción de controles internos en las etapas del proceso de concesión de microcréditos (promoción, verificación y evaluación); y la adopción de la Unidad Centralizada de Aprobación permitirán administrar el riesgo de crédito en la IMF en el Ecuador. El objetivo principal es estructurar el modelo de gestión de riesgo de crédito para IMF, mismo que se adapte al contexto del mercado financiero ecuatoriano. Los objetivos secundarios se detallan a continuación: Analizar la evolución de la cartera de microcrédito en el Ecuador. Estructurar el modelo de scoring de crédito de comportamiento. Analizar debilidades en la metodología tradicional de microcrédito con el fin de implementar controles internos. Estructurar un modelo integral en la concesión de microcréditos. La metodología es un estudio bibliográfico de las mejores prácticas adoptadas en la gestión de riesgo de crédito. Adicionalmente, es una recopilación de buenas prácticas implementadas en la concesión de microcréditos en las Instituciones Financieras del Ecuador.

Transpolar voltage and polar cap flux during the substorm cycle and steady convection events

Transpolar voltages observed during traversals of the polar cap by the Defense Meteorological Satellite Program (DMSP) F-13 spacecraft during 2001 are analyzed using the expanding-contracting polar cap model of ionospheric convection. Each of the 10,216 passes is classified by its substorm phase or as a steady convection event (SCE) by inspection of the AE indices. For all phases, we detect a contribution to the transpolar voltage by reconnection in both the dayside magnetopause and in the crosstail current sheet. Detection of the IMF influence is 97% certain during quiet intervals and >99% certain during substorm/SCE growth phases but falls to 75% in substorm expansion phases: It is only 27% during SCEs. Detection of the influence of the nightside voltage is only 19% certain during growth phases, rising during expansion phases to a peak of 96% in recovery phases: During SCEs, it is >99%. The voltage during SCEs is dominated by the nightside, not the dayside, reconnection. On average, substorm expansion phases halt the growth phase rise in polar cap flux rather than reversing it. The main destruction of the excess open flux takes place during the 6- to 10-hour interval after the recovery phase (as seen in AE) and at a rate which is relatively independent of polar cap flux because the NENL has by then retreated to the far tail. The best estimate of the voltage associated with viscous-like transfer of closed field lines into the tail is around 10 kV.

Simultaneous observations of reconnection pulses at Cluster and their effects on the cusp aurora seen at Chinese Yellow River Station

While the Cluster spacecraft were located near the high-latitude magnetopause, between 10:10 and 10:40 UT on 16 January 2004, three typical flux transfer event (FTE) signatures were observed. During this interval, simultaneous and conjugated all-sky camera measurements, recorded at Yellow River Station, Svalbard, are available at 630.0 and 557.7nm that show poleward-moving auroral forms (PMAFs), consistent with magnetic reconnection at dayside magnetopause. Simultaneous FTEs seen at the magnetopause mainly move northward, but having duskward (eastward) and tailward velocity components, roughly consistent with the observed direction of motion of the PMAFs in all-sky images. Between the PMAFs meridional keograms, extracted from the all-sky images, show intervals of lower intensity aurora which migrate equatorward just before the PMAFs intensify. This is strong evidence for an equatorward eroding and poleward moving open-closed boundary (OCB) associated with a variable magnetopause reconnection rate under variable IMF conditions. From the durations of the PMAFs we infer that the evolution time of FTEs is 5-11 minutes from its origin on magnetopause to its addition to the polar cap.

Centennial changes in the heliospheric magnetic field and open solar flux: the consensus view from geomagnetic data and cosmogenic isotopes and its implications

Svalgaard and Cliver (2010) recently reported a consensus between the various reconstructions of the heliospheric field over recent centuries. This is a significant development because, individually, each has uncertainties introduced by instrument calibration drifts, limited numbers of observatories, and the strength of the correlations employed. However, taken collectively, a consistent picture is emerging. We here show that this consensus extends to more data sets and methods than reported by Svalgaard and Cliver, including that used by Lockwood et al. (1999), when their algorithm is used to predict the heliospheric field rather than the open solar flux. One area where there is still some debate relates to the existence and meaning of a floor value to the heliospheric field. From cosmogenic isotope abundances, Steinhilber et al. (2010) have recently deduced that the near-Earth IMF at the end of the Maunder minimum was 1.80 ± 0.59 nT which is considerably lower than the revised floor of 4nT proposed by Svalgaard and Cliver. We here combine cosmogenic and geomagnetic reconstructions and modern observations (with allowance for the effect of solar wind speed and structure on the near-Earth data) to derive an estimate for the open solar flux of (0.48 ± 0.29) × 1014 Wb at the end of the Maunder minimum. By way of comparison, the largest and smallest annual means recorded by instruments in space between 1965 and 2010 are 5.75 × 1014 Wb and 1.37 × 1014 Wb, respectively, set in 1982 and 2009, and the maximum of the 11 year running means was 4.38 × 1014 Wb in 1986. Hence the average open solar flux during the Maunder minimum is found to have been 11% of its peak value during the recent grand solar maximum.

Simultaneous observations of reconnection pulses at Cluster and their effects on the cusp aurora observed at the Chinese Yellow River station

While the Cluster spacecraft were located near the high-latitude magnetopause, between 1010 and 1040 UT on 16 January 2004, three typical flux transfer event (FTE) signatures were observed. During this interval, simultaneous and conjugated all‐sky camera measurements, recorded at Yellow River Station, Svalbard, are available at 630.0 and 557.7 nm that show poleward‐moving auroral forms (PMAFs), consistent with magnetic reconnection at the dayside magnetopause. Simultaneous FTEs seen at the magnetopause mainly move northward, but having duskward (eastward) and tailward velocity components, roughly consistent with the observed direction of motion of the PMAFs in all‐sky images. Between the PMAFs meridional keograms, extracted from the all‐sky images, show intervals of lower intensity aurora which migrate equatorward just before the PMAFs intensify. This is strong evidence for an equatorward eroding and poleward moving open‐closed boundary associated with a variable magnetopause reconnection rate under variable IMF conditions. From the durations of the PMAFs, we infer that the evolution time of FTEs is 5–11 minutes from its origin on the magnetopause to its addition to the polar cap.

On the importance of interplanetary magnetic field (By)on polar cap patch formation

A number of poleward moving events were observed between 1130 and 1300 UT on 11 February 2004, during periods of southward interplanetary magnetic field (IMF), while the steerable antenna of the European Incoherent Scatter (EISCAT) Svalbard radar (ESR)and the Tromsø VHF radar pointed nearly northward at low elevation. In this interval, simultaneous SuperDARN CUTLASS Finland radar measurements showed poleward moving radar aurora forms (PMRAFs) which appeared very similar to the density enhancements observed by the ESR northward pointing antenna. These events appeared quasiperiodically with a period of about 10 min. Comparing the observations from the above three radars, it is inferred that there is an almost one‐to‐one correspondence between the poleward moving plasma concentration enhancements (PMPCEs) observed by the ESR and the VHF radar and the PMRAFs measured by the CUTLASS Finland radar. These observations are consistent with the interpretation that the polar cap patch material was generated by photoionization at subauroral latitudes and that the plasma was structured by bursts of magnetopause reconnection giving access to the polar cap. There is clear evidence that plasma structuring into patches was dependent on the variability in IMF |By|. The duration of these events implies that the average evolution time of the newly opened flux tubes from the subauroral region to the polar cap was about 33 min.

Predicting space climate change

The recent decline in the open magnetic flux of the Sun heralds the end of the Grand Solar Maximum (GSM) that has persisted throughout the space age, during which the largest‐fluence Solar Energetic Particle (SEP) events have been rare and Galactic Cosmic Ray (GCR) fluxes have been relatively low. In the absence of a predictive model of the solar dynamo, we here make analogue forecasts by studying past variations of solar activity in order to evaluate how long‐term change in space climate may influence the hazardous energetic particle environment of the Earth in the future. We predict the probable future variations in GCR flux, near‐Earth interplanetary magnetic field (IMF), sunspot number, and the probability of large SEP events, all deduced from cosmogenic isotope abundance changes following 24 GSMs in a 9300‐year record.

Inner plasma structure of the low-latitude reconnection layer

We report a clear transition through a reconnection layer at the low-latitude magnetopause which shows a complete traversal across all reconnected field lines during northwestward interplanetary magnetic field (IMF) conditions. The associated plasma populations confirm details of the electron and ion mixing and the time history and acceleration through the current layer. This case has low magnetic shear with a strong guide field and the reconnection layer contains a single density depletion layer on the magnetosheath side which we suggest results from nearly field-aligned magnetosheath flows. Within the reconnection boundary layer, there are two plasma boundaries, close to the inferred separatrices on the magnetosphere and magnetosheath sides (Ssp and Ssh) and two boundaries associated with the Alfvén waves (or Rotational Discontinuities, RDsp and RDsh). The data are consistent with these being launched from the reconnection site and the plasma distributions are well ordered and suggestive of the time elapsed since reconnection of the field lines observed. In each sub-layer between the boundaries the plasma distribution is different and is centered around the current sheet, responsible for magnetosheath acceleration. We show evidence for a velocity dispersion effect in the electron anisotropy that is consistent with the time elapsed since reconnection. In addition, new evidence is presented for the occurrence of partial reflection of magnetosheath electrons at the magnetopause current layer.

Comparison of the open-closed separatrix in a global magnetospheric simulation with observations: the role of the ring current

The development of global magnetospheric models, such as Space Weather Modeling Framework (SWMF), which can accurately reproduce and track space weather processes has high practical utility. We present an interval on 5 June 1998, where the location of the polar cap boundary, or open-closed field line boundary (OCB), can be determined in the ionosphere using a combination of instruments during a period encompassing a sharp northward to southward interplanetary field turning. We present both point- and time-varying comparisons of the observed and simulated boundaries in the ionosphere and find that when using solely the coupled ideal magnetohydrodynamic magnetosphere-ionosphere model, the rate of change of the OCB to a southward turning of the interplanetary field is significantly faster than that computed from the observational data. However, when the inner magnetospheric module is incorporated, the modeling framework both qualitatively, and often quantitatively, reproduces many elements of the studied interval prior to an observed substorm onset. This result demonstrates that the physics of the inner magnetosphere is critical in shaping the boundary between open and closed field lines during periods of southward interplanetary magnetic field (IMF) and provides significant insight into the 3-D time-dependent behavior of the Earth's magnetosphere in response to a northward-southward IMF turning. We assert that during periods that do not include the tens of minutes surrounding substorm expansion phase onset, the coupled SWMF model may provide a valuable and reliable tool for estimating both the OCB and magnetic field topology over a wide range of latitudes and local times.
