Conditions Ensuring the Decomposition of Asset Demand for All Risk-Averse Investors

Abstract

The paper explores how the demand for a risky asset can be decomposed into an investment effect and a hedging effect by all risk-averse investors. This question has been shown to be complex when considered outside of the mean-variance framework. Dependence among returns on the risky assets is restricted to quadrant dependence and it is found that the demand for one risky asset can be decomposed into an investment component based on the risk premium offered by the asset and a hedging component used against the fluctuations in the return on the other risky asset. The paper also discusses how the class of quadrant-dependent distributions is related to that of two-fund separating distributions. This contribution opens up the search for broader distributional hypotheses suitable to asset demand models. Examples are discussed.     

The dynamics of privatization, the legal environment and stock market development

In this paper, we examine under which conditions privatization is an effective means to develop local stock markets for a panel of 61 countries over the last twenty four years. By addressing the endogeneity between privatization and stock market development, we show for the 1980-98 period that the initial legal environment is a significant contemporary determinant of stock market development, while privatization is not. When we examine the dynamics of privatization in interaction with the legal environment, we find that privatization has a two-year-lagged effect on stock market development in emerging markets, and a one-year-lagged effect in developed countries. Results for the 1999-2003 period seem to be largely affected by the global crash that followed the Asian crisis.     

Consequential creativity

Creativity is an original cognitive ability and problem solving process which enables individuals to use their intelligence in a way that is unique and directed toward coming up with a product. Architectural education is one of the fields in which human creativity has been exhibited; because, it can be defined as a design study that correlates with other disciplines: social sciences, management, history, operational research, philosophy, graphic design, math and etc. These features which distinguish architecture from other disciplines ascribe different kind of responsibilities for architectural education; since beside technical and professional skills, an architect must have imagination and to be creative at many levels. Thus, this research aims at proving that students can be trained in creative thinking via acquiring specific skills and systematic techniques, which directly acts on design product. The study methodology depends on the concept of experimental research that targets at exposing students to creative problem solving experience via carrying out a creative training course that concerns “Consequential Creativity”. That experiment examined the potentiality of enhancing the students’ ability of viewing problems in non-traditional perspectives that counts on the systematic procedures of problem solving. Tools for assessment before and after training have been implemented. The Experiment findings proved that the students’ creative thinking skill has been clearly improved after attending the course. Therefore, training in creative thinking can be considered as independent courses or within specific architectural curricula.     

Small- and medium-sized enterprise internationalization: Towards the knowledge-based model

Firm internationalization research has grown throughout the last 50 years resulting in a number of theories and models. Although each theory and model enables us to see some parts of the picture, a holistic approach is needed to provide us a full picture. The so-called knowledge-based models proposed so far drew upon the transaction cost theory, the social capital theory, and the knowledge management models. This paper reviews previous research and builds a more comprehensive knowledge-based model of small- and medium-sized enterprises internationalization. The model includes “knowledge factors”, which we identified from internationalization literature. These include the market knowledge and the experiential knowledge composed of network knowledge, cultural knowledge, and entrepreneurial knowledge. Acquisition as well as utilization of each kind of knowledge during the different phases of internationalization is presented. The model is a step towards deeper understanding of the role of knowledge in SME internationalization.     

Foreign Direct Investment,Financial Development and Their Impact on the GDP Growth in Low-income Countries

ABSTRACT

This essay empirically studies the effects and causal links between foreign direct investment (FDI), financial development (FD) and economic growth. The sample consists of the main economies of low-income countries and the study covers the period 1990–2015. The results of the estimate show that, under certain specific economic conditions, FDI affects positively the level of long-term economic growth; it thus makes it possible to improve the economic situation of these countries. Using Johansen’s cointegration technique, the results find that FD; FDI and GDP growth are cointegrated, that shows the pursuit of the long-term equilibrium relationship between them. The error correction model confirms the existence of a double causal relationship between FDI and GDP growth, and between FD and FDI and between GDP growth and FD.     

The impact of the dimensions of social performance on firm risk

This paper examines the impact of the individual dimensions of social performance (SP) on firm risk (total and idiosyncratic) using 16,599 firm-year observations over the period 1991–2007. We find that firm risk for S&P500 members is positively affected by Employee, Diversity, and Corporate Governance concerns. On the other hand, Community (Diversity) strengths negatively (positively) affect their risk. As to non-S&P500 members, firm risk is positively affected by Employee concerns and Diversity strengths. However, firm risk of non-S&P500 members is negatively affected by Environment strengths. The direction of causation between firm risk and SP depends on the dimension examined.     

ISLAMIC BANKING,COSTLY RELIGIOSITY,AND COMPETITION

In this article we explain how Islamic banks (IBs) maximize profitability in the presence of costly religiosity. Because of strong competition between IBs and conventional banks (CBs), a unique equilibrium emerges that affects the IB pricing structure. We propose a new model that identifies the optimal rate on the asset and liability sides of IBs. It shows that the financial products offered by IBs are not an exogenous function of religiosity; instead, they are endogenously determined by the nature of market forces in which IBs are operating. We show that in the presence of costly religiosity and competition, the rates of both converge. Moreover, the competitive pricing mechanism induces IBs to structure their asset- and liability-side financial products (particularly Murabaha) with a risk profile similar to that of the CB loan system. This article empirically supports the theoretical propositions by using data from 17 Muslim majority countries where both IBs and CBs coexist from 2000 to 2015. We find that, holding other factors of bank returns constant, competition significantly affects IB asset- and liability-side returns. The analysis also reveals that because of increasing competition between IBs and CBs, the market power of IBs has significantly declined over time.     

Dynamic portfolio optimization with liquidity cost and market impact: a simulation-and-regression approach

We present a simulation-and-regression method for solving dynamic portfolio optimization problems in the presence of general transaction costs, liquidity costs and market impact. This method extends the classical least squares Monte Carlo algorithm to incorporate switching costs, corresponding to transaction costs and transient liquidity costs, as well as multiple endogenous state variables, namely the portfolio value and the asset prices subject to permanent market impact. To handle endogenous state variables, we adapt a control randomization approach to portfolio optimization problems and further improve the numerical accuracy of this technique for the case of discrete controls. We validate our modified numerical method by solving a realistic cash-and-stock portfolio with a power-law liquidity model. We identify the certainty equivalent losses associated with ignoring liquidity effects, and illustrate how our dynamic optimization method protects the investor's capital under illiquid market conditions. Lastly, we analyze, under different liquidity conditions, the sensitivities of certainty equivalent returns and optimal allocations with respect to trading volume, stock price volatility, initial investment amount, risk aversion level and investment horizon.     

The (home) bias of European central bankers: new evidence based on speeches

Speeches are an important vehicle for central bankers to convey individual views on the preferred policy stance. In this article, we employ an automated text linguistic approach to create an indicator that measures the tone of the 1,618 speeches delivered by members of the Governing Council (GC) during the period 1999M1–2014M4. We then relate this variable to euro area and national macroeconomic forecasts. Our key findings are as follows. First, inflation and growth expectations have a positive and significant impact on the hawkishness of a speech. Second, different growth expectations across the euro area and different preferences significantly explain discrepancies across speakers. Third, the voiced preferences of presidents of the national central banks (NCBs) largely coincide with the level of independence their central banks had at the time of the Maastricht Treaty. However, in general, there are not much differences between members of the Executive Board and the NCB presidents. Fourth, we find some evidence that central bankers adjust the gist of their speeches depending on whether they talk at home or abroad and before or after a GC meeting. Finally, differences in central banker preferences are the key source of variation in their speeches before the financial crisis.
