Interest rate (in)sensitivity of emerging market corporate debt : economic analysis based on 2002-2015 empirical evidence

Interest rate sensitivity assessment framework based on fixed income yield indexes is developed and applied to two types of emerging market corporate debt: investment grade and high yield exposures. Our research advances beyond the correlation analyses focused on co- movements in yields and/or spreads of risky and risk-free assets. We show that correlation- based analyses of interest rate sensitivity could appear rather inconclusive and, hence, we investigate the bottom line profit and loss of a hypothetical model portfolio of corporates. We consider historical data covering the period 2002 – 2015, which enable us to assess interest rate sensitivity of assets during the development, the apogee, and the aftermath of the global financial crisis. Based on empirical evidence, both for investment and speculative grades securities, we find that the emerging market corporates exhibit two different regimes of sensitivity to interest rate changes. We observe switching from a positive sensitivity under the normal market conditions to a negative one during distressed phases of business cycles. This research sheds light on how financial institutions may approach interest rate risk management, evidencing that even plain vanilla portfolios of emerging market corporates, which on average could appear rather insensitive to the interest rate risk in fact present a binary behavior of their interest rate sensitivities. Our findings allow banks and financial institutions for optimizing economic capital under Basel III regulatory capital rules.

LA CRISIS FINANCIERA: ¿ESTAFA, MALA GESTIÓN EMPRESARIAL, MAL MANEJO MACROECONÓMICO O UNA FALTA DE REGULACIONES? DE NUEVO LAS ENSEÑANZAS

Resumen La intensificación de la crisis a nivel global, luego de la bancarrota de Lehman Brothers en septiembre del 2008, ha provocado que el actual entorno económico y financiero sea complicado para la economía mundial, el sector financiero a nivel global y para los bancos centrales. La actual crisis deriva de muchas causas; no obstante las principales son tres: primero, aspectos macroeconómicos; segundo, la inadecuada regulación de los entes encargados, y tercero, los reguladores estimularon el rápido crecimiento de los derivados en el mercado OTC. Abstract The amplification of the global financial crisis, following the bankruptcy of Lehman Brothers in September 2008, has made the present economic and financial environment a not easy time for the world economy, the global financial system and for central banks. There are many causes from the recent financial crisis. Main could be three. First, there were macroeconomic components. Second, the inadequate oversight/regulation provided by financial market regulators. And third, federal regulators have actively encouraged the rapid growth of over-the-counter (OTC) derivatives and securities by all types of financial institutions.

Hybridity in contemporary commercial organizations: implications for employee trust

This study advances the concept of organizational hybridity (OH). By doing so, it takes into account the individual level of analysis often neglected in organizational theory. More specifically, it aims to understand the implications of organizational hybridity for employees’ trust in contemporary commercial organizations. Informed and guided by current literature, this study argues that the current literature on organizational hybridity fails to adequately address the consequences of hybridity for employees' behaviour. The empirical study was conducted in 2014 using data collected via semi-structured interviews and document analysis. The study was based on a comparison of two case studies in Nigeria: Alter Securities Limited and Barak Petroleum Limited. A total of forty (40) interviews were conducted; twenty (20) from each organization. The data were analysed using thematic analysis. The main findings are that organizational hybridity in this study produced tensions that resulted in negative behavioural responses and employees’ distrust in the commercial hybrid organizations. However, employees’ identification with non-market orientated institutional logics such as family, philanthropic and religious logics is seen to facilitate their commitment, honesty, and trust in the organizations. Nevertheless, caution is required here as religious logics may also lead to an acceptance of unethical behaviour by employees. Overall, this study contributes to the literature on organizational hybridity by extending on Battilana and Lee’s (2014) framework, which highlights governance, leadership, organizational culture and intra-organizational relationships as core organizational attributes in the context of which issues may arise in commercial hybrid organizations. Furthermore, it addresses a gap in Besharov and Smith’s (2014) hybrid typology framework by providing an alternative line of argument focused on understanding how tensions manifest within commercial hybrid organizations. The key recommendations of this research underscore the need for commercial hybrid organizations to invest in mechanisms for improving employees’ trust so as to reap the benefits associated with trust. This could be achieved by involving employees in the decision-making process and clearly communicating the organizations’ values, so as to minimise the misinterpretation of the embodied institutional logics by employees.

Synthetic portfolio for event studies: Estimating the effects of volatility call auctions

We propose a method denoted as synthetic portfolio for event studies in market microstructure that is particularly interesting to use with high frequency data and thinly traded markets. The method is based on Synthetic Control Method and provides a robust data driven method to build a counterfactual for evaluating the effects of the volatility call auctions. We find that SMC could be used if the loss function is defined as the difference between the returns of the asset and the returns of a synthetic portfolio. We apply SCM to test the performance of the volatility call auction as a circuit breaker in the context of an event study. We find that for Colombian Stock Market securities, the asynchronicity of intraday data reduces the analysis to a selected group of stocks, however it is possible to build a tracking portfolio. The realized volatility increases after the auction, indicating that the mechanism is not enhancing the price discovery process.
