Capital Markets and Foreign Ownership Restrictions: An Empirical Analysis of Emerging Stock Markets

In the 1990s, the hot issue in international finance was the growing interest of portfolio managers in the emerging stock markets. The interest in the emerging markets gained rapid attention, which is evident from the global trends, towards the opening up of economies and financial markets, free capital flow and the privatisation of financial institutions. Earlier the emerging markets were isolated due to several factors that had posed serious problems for international investors. These markets lacked the depth, regulatory framework, and structural safeguards that had characterised the equity markets in the developed world. Capital markets are called integrated, if assets with perfectly correlated rates of returns have the same price regardless of the location in which they are traded. Alternatively, capital market are called segmented, if financial assets traded in different markets “with identical risk characteristics” have different returns due to different investment restrictions.1 Segmentation may be due to individuals’ attitudes, government restrictions over capital movements or irrationality. In the past twenty-five years, modern finance theory has proved to be a major development in finance, which comprises of portfolio theory, capital market theory and efficient market theory. These modern developments can be traced back to the work of Markowitz (1959); Sharpe (1964); Solnik (1974) etc., which assumes that security prices fully reflect all publicly available information. Due to this information, potential investors can gain benefits through international diversification. The major attraction of forming international portfolios lies in the potential for risk reduction through diversification of unsystematic risk.

Fermions Tunneling from Charged Accelerating and Rotating Black Holes with NUT Parameter

This paper is devoted to the study of Hawking radiation as a tunneling of charged fermions through event horizons of a pair of charged accelerating and rotating black holes with NUT parameter. We evaluate tunneling probabilities of outgoing charged particles by using the semiclassical WKB approximation to the general covariant Dirac equation. The Hawking temperature corresponding to this pair of black holes is also investigated. For the zero NUT parameter, we find results consistent with those already available in the literature.Comment: 21 pages, no figur

Quantum Corrections for a Bardeen Regular Black Hole

In this paper, we study the quantum corrections to the thermodynamical quantities (temperature and entropy) for a Bardeen charged regular black hole by using a quantum tunneling approach over semiclassical approximations. Taking into account the quantum effects, the semiclassical Bekenstein-Hawking temperature and the area law are obtained, which are then used in the first law of thermodynamics to evaluate corrections to these quantities. It is interesting to mention here that these corrections reduce to the corresponding corrections for the Schwarzschild black hole when the charge $e=0$.Comment: 14 pages, accepted for publication in J.

The Role of Small and Medium-size Enterprises (SMEs) in the Socio-economic Stability of Karachi.

The purpose of this study is to identify the core constraints in financing of SMEs in Karachi that impede their growth and even undermine their liquidity and financial position. Literature review: The problems and constraints are faced by small and medium-size enterprises (SMEs) in Karachi with regard to access to financing. Along with Karachi, the other cities and areas in Pakistan are facing alike problems. Methods: This study is exploratory in nature and includes quantitative and qualitative data. Data was collected through well designed questionnaire from a sample group of 500 respondents of SMEs in Karachi. In addition, one-on-one formal and informal interviews were also taken from various businessmen and bankers. Conceptual Model: A conceptual model/ framework were devised to test and ascertain the statistical validity of the study. It includes dependent variable SME financing, and independent variables, financing constraints, functional/ internal barriers, government support and incentives, and SMEs growth and development. Findings: The findings revealed that most people/ SMEs feel reluctant to borrow from banks and financial institutes because of stringent collateral requirements, high mark up, lengthy and convoluted documentary process, and to some extent malpractices at banks and financial institutions. The preference of the lending institutions is to finance the large-scale corporate sector. The results of the data analysis confirmed profound relation of dependent and independent variables and accepted the hypotheses. Conclusion: A substantial portion of SMEs possesses great potential of growth. There exists unending opportunities to tap, while banking and financial system in Karachi and Pakistan enjoys enough liquidity but SMEs are unable to enjoy financial leverage because of various financial constraints, lack of support by government institutions and policy makers, and internal weaknesses and flaws of SMEs in managing their businesses. Finally recommendations were lodged.Small and Medium enterprise; constraints in financing; Socio-economic Sustainability
