A Study Of Chit Finance In Kerala With Special Emphasis On Kerala State Financial Enterprises Ltd.

Chit funds contribute to the value of financial markets in India particularly in Kerala. Chit finances with its unique features are of great significance especially as a savings cum borrowing avenue. The present study entitled “A Study of chit Finance in Kerala with special emphasis on Kerala State Financial Enterprises Ltd.” examines the socio-economic aspects of Chit schemes run by the private Chit Funds, KSFE, co-operatives, and informal Chit Funds. The study is an attempt to find the reasons for the growing popularity of Chit Funds as savings cum borrowings avenues even in the presence of various other avenues of savings and borrowings and also to understand how the Chit subscribers utilize the funds. The objectives of the present study are to examine the trends and pattern of growth of Chit Funds in the formal sector in Kerala, performance of KSFE as the only public sector Chit Fund company in India, preference for joining Chit Funds, estimate the cost and return on Chit Funds etc. is an indigenous financial instrument is complementary to modern financial techniques of savings and borrowings. KSFE is the dominant foremen in the chit business in Kerala, its weaknesses result in the non-attainment of certain objectives. Driven by the growing trend of privatization, KSFE needs to be innovative and competitive. It is also necessary that KSFE continue its leadership role by being more effective in being the harbinger of more efficiency, professionalism and good governance in the Chit Fund Industry. The growth and development of chit business by protecting the interests of both the subscribers and the foremen will therefore be most beneficial for any growing economy.

Análisis del impacto del tamaño de los activos en la cuenta de resultados mediante la utilización de espacios de fase y análisis de recurrencia

Los resultados financieros de las organizaciones son objeto de estudio y análisis permanente, predecir sus comportamientos es una tarea permanente de empresarios, inversionistas, analistas y académicos. En el presente trabajo se explora el impacto del tamaño de los activos (valor total de los activos) en la cuenta de resultados operativos y netos, analizando inicialmente la relación entre dichas variables con indicadores tradicionales del análisis financiero como es el caso de la rentabilidad operativa y neta y con elementos de estadística descriptiva que permiten calificar los datos utilizados como lineales o no lineales. Descubriendo posteriormente que los resultados financieros de las empresas vigiladas por la Superintendencia de Sociedades para el año 2012, tienen un comportamiento no lineal, de esta manera se procede a analizar la relación de los activos y los resultados con la utilización de espacios de fase y análisis de recurrencia, herramientas útiles para sistemas caóticos y complejos. Para el desarrollo de la investigación y la revisión de la relación entre las variables de activos y resultados financieros se tomó como fuente de información los reportes financieros del cierre del año 2012 de la Superintendencia de Sociedades (Superintendencia de Sociedades, 2012).

Utilización de los conceptos de caos y complejidad en empresas del sector financiero

Este proyecto busca determinar que utilización se hace de los conceptos de caos y complejidad en las empresas del sector financiero colombiano, para así encontrar la relación entre estos conceptos y la ocurrencia de eventos en la economía actual. Se adoptó un método descriptivo, donde se tomará como unidad de análisis una empresa representativa del sector financiero de Colombia. La compañía escogida para el análisis fue Bancolombia, la cual debido a su larga trayectoria dentro de la economía colombiana, ha demostrado un buen desempeño y el logro de sus objetivos a nivel nacional e internacional. El análisis realizado permitió tener una visión amplia y representativa del significado que el caos y la complejidad tienen para el sector financiero; y como sus respectivos conceptos se aplican a la hora de enfrentar condiciones extremas en la industria o la economía. Pero también como el comportamiento de variables pertenecientes a otras industrias, tienen la capacidad de afectar e influir en el normal comportamiento de la compañía. Se concluyó además que Bancolombia en épocas de crisis logra ser mucho más realista al afrontar los momentos. Las crisis se muestran como caos dentro de un sistema simple y organizado que afecta a sus diferentes variables no lineales, y que puede llegar a una interacción entre otros sistemas, produciendo así comportamientos críticos y complicados. Se muestra también que la complejidad dentro de un sistema financiero es una creación de interacciones simples que muestran un parámetro claro, casi deducible, que al interactuar entre todas se convierte en complejidad para las organizaciones como Bancolombia.

International financial centres, office market rents and volatility

Despite continuing developments in information technology and the growing economic significance of the emerging Eastern European, South American and Asian economies, international financial activity remains strongly concentrated in a relatively small number of international financial centres. That concentration of financial activity requires a critical mass of office occupation and creates demand for high specification, high cost space. The demand for that space is increasingly linked to the fortunes of global capital markets. That linkage has been emphasised by developments in real estate markets, notably the development of global real estate investment, innovation in property investment vehicles and the growth of debt securitisation. The resultant interlinking of occupier, asset, debt and development markets within and across global financial centres is a source of potential volatility and risk. The paper sets out a broad conceptual model of the linkages and their implications for systemic market risk and presents preliminary empirical results that provide support for the model proposed.

The impact of 9/11 on US REIT returns: fundamental or financial?

Following the attack on the World Trade Center on 9/11 volatility of daily returns of the US stock market rose sharply. This increase in volatility may reflect fundamental changes in the economic determinants of prices such as expected earnings, interest rates, real growth and inflation. Alternatively, the increase in volatility may simply reflect the effects of increased uncertainty in the financial markets. This study therefore sets out to determine if the effects of the attack on the World Trade Center on 9/11 had a fundamental or purely financial impact on US real estate returns. In order to do this we compare pre- and post-9/11 crisis returns for a number of US REIT indexes using an approach suggested by French and Roll (1986), as extended by Tuluca et al (2003). In general we find no evidence that the effects of 9/11 had a fundamental effect on REIT returns. In other words, we find that the effect of the attack on the World Trade Center on 9/11 had only a financial effect on REIT returns and therefore was transitory.

Inglorious revolution : sovereign debt, tropical credibility, and financial underdevelopment in imperial Brazil

In 1824 the creation of institutions that constrained the monarch’s ability to unilaterally tax, spend, and debase the currency put Brazil on a path toward a revolution in public finance, roughly analogous to the financial consequences of England’s Glorious Revolution. This credible commitment to honor sovereign debt resulted in successful long-term funded borrowing at home and abroad from the 1820s through the 1880s that was unrivalled in Latin America. Some domestic bonds, denominated in the home currency and bearing exchange clauses, eventually circulated in European financial markets. The share of total debt accounted for by long-term funded issues grew, and domestic debt came to dominate foreign debt. Sovereign debt yields fell over time in London and Rio de Janeiro, and the cost of new borrowing declined on average. The market’s assessment of the probability of default tended to decrease. Imperial Brazil enjoyed favorable conditions for borrowing, and escaped the strong form of “original sin” stressed by recent work on sovereign debt. The development of vibrant private financial markets did not, however, follow from the enhanced credibility of government debt. Private finance in Imperial Brazil suffered from politicized market interventions that undermined the development of domestic capital markets. Private interest rates remained high, entry into commercial banking was heavily restricted, and limited-liability joint-stock companies were tightly controlled. The Brazilian case provides a powerful counterexample to the general proposition of North and Weingast that institutional changes that credibly commit the government to honor its obligations necessarily promote the development of private finance. The very institutions that enhanced the credibility of sovereign debt permitted the systematic repression of private financial development. In terms of its consequences for domestic capital markets, the liberal Constitution of 1824 represented an “inglorious” revolution.

A Generic Model of Financial Repression

The paper develops a growth model in an overlapping generations framework of a financially repressed small open economy, and analyzes the effects of financial liberalization. The following observations are made: An increase (decrease) of interest rate (reserve requirements) reduces (increases) the steady-state stock of capital and the trade balance, but improves (deteriorates) the level of foreign exchange reserves. However, financial liberalization, in any form, is always welfare-improving. The paper, thus, advocates financial liberalization policies to be oriented towards reduction of reserve requirements rather than interest rate deregulation, if foreign reserve holding is not in a critical position.

Asymmetric Information, Tax Evasion and Alternative Instruments of Government Revenue

Using a pure-exchange overlapping generations model, characterized with tax evasion and information asymmetry between the government (the social planner) and the financial intermediaries, we try and seek for the optimal tax and seigniorage plans, derived from the welfare maximizing objective of the social planner. We show that irrespective of whether the economy is characterized by tax evasion, or asymmetric information, a benevolent social planner, maximizing welfare and simultaneously financing the budget constraint, should optimally rely on explicit rather than implicit taxation.

Dynamic Effects of Currency Depreciation on Stock Market Returns during the Asian Financial Crisis

The current international integration of financial markets provides a channel for currency depreciation to affect stock prices. Moreover, the recent financial crisis in Asia with its accompanying exchange rate volatility affords a case study to examine that channel. This paper applies a bivariate GARCH-M model of the reduced form of stock market returns to investigate empirically the effects of daily currency depreciation on stock market returns for five newly emerging East Asian stock markets during the Asian financial crisis. The evidence shows that the conditional variances of stock market returns and depreciation rates exhibit time-varying characteristics for all countries. Domestic currency depreciation and its uncertainty adversely affects stock market returns across countries. The significant effects of foreign exchange market events on stock market returns suggest that international fund managers who invest in the newly emerging East Asian stock markets must evaluate the value and stability of the domestic currency as a part of their stock market investment decisions.

An econometric analysis of ETF and ETF futures in financial and energy markets using generated regressors

It is well known that that there is an intrinsic link between the financial and energy sectors, which can be analyzed through their spillover effects, which are measures of how the shocks to returns in different assets affect each other’s subsequent volatility in both spot and futures markets. Financial derivatives, which are not only highly representative of the underlying indices but can also be traded on both the spot and futures markets, include Exchange Traded Funds (ETFs), which is a tradable spot index whose aim is to replicate the return of an underlying benchmark index. When ETF futures are not available to examine spillover effects, “generated regressors” may be used to construct both Financial ETF futures and Energy ETF futures. The purpose of the paper is to investigate the covolatility spillovers within and across the US energy and financial sectors in both spot and futures markets, by using “generated regressors” and a multivariate conditional volatility model, namely Diagonal BEKK. The daily data used are from 1998/12/23 to 2016/4/22. The data set is analyzed in its entirety, and also subdivided into three subset time periods. The empirical results show there is a significant relationship between the Financial ETF and Energy ETF in the spot and futures markets. Therefore, financial and energy ETFs are suitable for constructing a financial portfolio from an optimal risk management perspective, and also for dynamic hedging purposes.

Do we need a resolution fund paid for by financial institutions? EuropEos Commentary No. 2, 17 May 2010

In this EuropEos Commentary, Stefano Micossi reviews recent efforts to build a stronger and more coherent regulatory system for financial markets and finds the idea of a resolution fund at best a distraction, and at worst a harbinger of renewed financial instability.
