Efficiency of Microfinance Institutions: A Data Envelopment Analysis

This study examines the cost efficiency of 39 microfinance institutions across Africa, Asia and the Latin America using non-parametric data envelopment analysis. Our findings show non-governmental microfinance institutions particularly; under production approach, are the most efficient and this result is consistent with their fulfillment of dual objectives: alleviating poverty and simultaneously achieving financial sustainability. However, bank-microfinance institutions also outperform in the measure of efficiency under intermediation approach. This result reflects that banks are the financial intermediaries and have access to local capital market. It may be possible that bank-microfinance institutions may outperform the non-governmental microfinance institutions in the long run.     

Loan Market Competition and Bank Risk-Taking

Recent literature (Boyd and De Nicoló, J Finance 60:1329–1343, 2005) has argued that competition in the loan market lowers bank risk by reducing the risk-taking incentives of borrowers. Using a model where competition arises from falling switching costs for entrepreneurs, we show that the impact of loan market competition on banks is reversed if banks can adjust their loan portfolios. The reason is that when borrowers become safer, banks want to offset the effect on their balance sheet and switch to higher-risk lending. They even overcompensate the effect of safer borrowers because loan market competition erodes their franchise values and thus increases their risk-taking incentives.     

Irreversible investment and discounting: an arbitrage pricing approach

This paper presents a unified approach to valuing investment projects under uncertainty, based on stochastic discount factors, by linking optimal stopping theory to the no-arbitrage principle in asset pricing. An investment threshold for the case where the discount factor and the project’s cash-flow both follow a geometric Brownian motion is derived. Comparative statics of the investment trigger are obtained adding to and clarifying on the uncertainty–investment debate. Finally, two different ways to obtain discount factors are illustrated: spanning assets and representative agent analysis. The link between the characteristics of these different approaches and the optimal investment policy is clarified.     

Constructing the Economy: The Role of Construction Sector in India’s Growth

On empirically examining the importance of construction sector in propelling economic growth rate in India, the study has found that in the presence of the dominant influence of capital stock, the impact of the construction sector gets blurred or neutralized. Once capital stock is dropped from the model, the construction sector emerges as a significant determinant of economic growth, while other financial variables such as interest rate and non-food bank credit including the financial liberalization dummy do not play significant roles in economic growth. However, from an investigation of the impact of the construction sector on economic growth through the channel of employment, it is seen that the construction sector might be impacting the growth rate through increasing employment and thereby increasing the aggregate output in the economy.     

Determinants of heterogeneity in European credit ratings

In this study, we empirically analyze the determinants of heterogeneity in rating assessments across different segments of the European loan market. We conduct a benchmarking analysis using rating information on European corporate obligors from nine major Austrian banks that have a large share of foreign lending, particularly in the Central and Eastern European region. We provide evidence that, generally, overall heterogeneity among rating outcomes for foreign markets is higher than for domestic markets. Furthermore, we show that heterogeneity increases in transition economies and those markets where Austrian bank involvement is relatively low. Our evidence supports the hypothesis that heterogeneity in the assessment of credit risk is determined not only by the objective quality of information, which is deemed to be lower in transition economies, but also by the subjective access to information about obligors measured by the level of domestic bank involvement in the respective foreign market. Furthermore, we quantify potential effects on regulatory capital requirements.     

Dancing in the dark: post-trade anonymity,liquidity and informed trading

We analyze the impact of post-trade anonymity on liquidity and informed trading in an order driven stock market. The German stock market introduced the Central Counterparty (CCP) in March 2003 for German equities traded on its anonymous electronic trading platform Xetra leading to a major change in its existing transparency regime. Before the introduction trader IDs were revealed to the counterparties of a trade, with the introduction of the CCP even after the transaction the traders remain anonymous. Previous theoretical and empirical research documents that pre-trade anonymity results in increased liquidity, while results on post-trade anonymity are mixed. We find a significant increase in liquidity measured through a reduction of 25% in implicit transaction costs. We also document that the arrival rate of informed traders is reduced in the anonymous setting. Following recent findings of Bloomfield et al. (J Finan Econ 75:165–199, 2005) that informed traders take on the role of liquidity providers we interpret our findings as indication that informed traders change their behavior in providing liquidity more aggressively in an anonymous environment.     

Beliefs regarding fundamental value and optimal investing

Standard optimal portfolio selection models take no account of the special information that active investors believe they possess. For example, active investors who believe they can place bounds on the price of a security will want to use that information when assessing risk and expected return in order to construct an optimal portfolio. In this paper, we use two continuous-time models to analyze how placing boundaries on the price of a stock affects assessed risk, expected returns, and the optimal holdings of an active investor, and how those vary as a function of the relation between the stock price and the boundaries. In particular, the optimal strategy takes significant long/short positions as the price nears its lower/upper boundary.     

With or without you: market quality of floor trading when screen trading closes early

Most stock markets are characterized by a number of parallel operating trading systems which interact intensively with each other. Usually, smaller trading platforms take the leading domestic main market as a benchmark in the price discovery process and for closing open trading positions. But what happens if the smaller trading systems suddenly have to act without this benchmark platform? We examine the effects of the reduction of the daily business hours of a screen based main trading system while a parallel floor based trading system keeps on operating. We provide evidence that liquidity improves while informed trading and informational efficiency of prices decrease at the floor based trading system as a result of the no longer operating main market. While prior research on parallel trading focuses on changes due to a growing number of trading venues, we present the first evidence on market effects when the main trading platform reduces trading hours.     

Wie man durch Moral ins „Geschäft“ kommt: Ein ordonomischer Beitrag zum betrieblichen Risikomanagement

Through an analysis of Alfred Krupp’s 19th-century social welfare program, this paper develops an ordonomic contribution to corporate risk management. The paper argues that companies can employ ‘morality as a factor of production’ by a differentiated business strategy of moral commitments. In this way, companies can not only considerably reduce their exposure to the undesirable risks of losing core business relationships with important stakeholders. But at the same time, businesses may increase their readiness to take desirable innovation risks that are pivotal for long-term value creation. Ultimately, the paper develops an argument for how companies can better live up to the role of being an agent of societal value creation, often articulated by concepts such as “corporate social responsibility” or “corporate citizenship”.
